2024 Cadillac Lyriq Complaint Log

Rear right light not working, then works, then it randomly stops working, complained to Cadillac but they keep saying nothing is wrong. I feel unsafe so to my light constantly going off especially dangerous driving at night or changing lanes on the road.

While driving northbound on [XXX], south of Oklahoma City, at normal highway speed, at night, in the rain (on [XXX]), this EV lost all power to the wheels and the regenerative braking ceased to function. It appears that all flow of electrons from the batteries to the drive motors, and from the regenerative brakes to the batteries stopped. I still had dashboard lights, steering, and conventional brakes. I was able to safely coast to a stop on the highway shoulder. I set the parking brakes, put the “transmission” into “park”, and turned off the power button. I then restarted the car, and all was normal again. I continued my drive from Austin, TX, to Evergreen, CO with no additional incidents, arriving on [XXX]. This is reminiscent of the “blue screen of death” in old Microsoft desktop computers — fixed the problem by cycling the ON / OFF switch. Unfortunately, doing this when driving at 75 mph is less than ideal, and is a real potential safety problem.

I am writing to report an issue with the windshield durability on my 2024 Cadillac LYRIQ. Over the past three weeks, I’ve experienced three separate instances where small rocks struck the windshield while I was driving, each impact resulting in a crack or chip. In my experience with previous vehicles, similar impacts would rarely, if ever, result in such immediate damage, which raises concerns about the material or design of this particular windshield. This frequent damage has quickly become costly and frustrating. Windshields should withstand small impacts to a reasonable extent, and this does not seem to be the case here. I am also reaching out to Cadillac to address my concerns, but I wanted to report this issue to NHTSA in case other drivers are experiencing similar problems. Please let me know if there is further information I can provide. Thank you for looking into this matter.

The bigger issue is the car will prematurely dim the display and dusk/dawn - making it very hard to see at those times - even with max dimmer setting. Took it to the dealer multiple times they say it’s working as expected but it’s a known issue for all lyriq owners that GM ignores

Lyriq display not bright enough prematurely dim the display and dusk/dawn - making it very hard to see at those times - even with max dimmer setting

Ref: NHTSA ID# 24V589/ GM Recall N242453471 Record shows that the above recall was completed on August 27, 2024. Yesterday while I was reversing my 2024 LYRIQ out of my garage I experienced multiple false automatic braking. Braking was so frequent that, I thought, driving that car at that time was unsafe and pulled it back into the garage and took my other car. It was raining at that time. False braking has happened in the past but not to a point where driving is nearly impossible.

While driving through Wisconsin on [XXX] with Super Cruise activated in 70MPH traffic the car provided me with driver's side collision warning failure notice and then a forward collision warning failure notice, but the car continued to be operating normally. A short time later a brakes overheating warning came on while the car still seemed to be operating normally and maintaining speed. I immediately disengaged the cruise control to check out the situation and the car instantly locked on the brakes, and we could see smoke and smell the burning brakes. I pulled to car to the side of the road, and we exited the car concerned there might be a fire coming from one of the 4 smoking wheels. The rotors were red hot. We remained a safe distance from the car until the brakes stopped smoking. After it appeared safe, I reentered the car and determined the brakes (parking brakes) were fully engaged and the car would not move. We contacted OnStar for assistance and waited. After a significant time (it seemed like quite a while) I suddenly heard the sound of the parking brakes electrically releasing. Shortly after that I started and tested the car again and it would move so we slowly drove it off the busy interstate to the next exit a short distance away and continued working with OnStar to obtain a tow to a Cadillac dealership. After working with OnStar for several hours and determining that there would most likely be no tow truck coming, we decided to test drive the car around the area now that the brakes had cooled off. We ended up renting a 'safety' car that my wife would drive, and I would try to drive the car back to Minnesota to our dealer. The car operated normally for the drive home, but we did not use any cruise control just in case. It was my belief that a system communication issue told the brakes to engage and that since the Super Cruise was engage the motors just added more power to over-come the drag on the brakes until they over heated.

Each time it rains and the car is in reverse, the emergency braking system kicks in repeatedly, and a red light flashes on the screen. The car believes there is an object or person behind the car; I would imagine because the rear camera can see the rain. It is difficult to even move the car at all, and is a major safety concern. The last time this occurred, I was backing out of my driveway at a slow speed. This also occurred backing out of a parking spot at a slow speed. I hesitate to drive this car in rain because of the issue. In speaking with the dealership's repair personnel, this occurs on every Lyriq. In fact, there was another Lyriq in for that complaint at the same time. I cannot attach photos or a video, as doing so would be unsafe. However, it can be easily re-created in any Lyriq.

AC compressor severe noise like a chopper.

Continuing problem with both front and rear emergency braking. Primarily when it is raining and vehicle is put in reverse violent and unexpected emergency braking will occur for no apparent reason. This will happen several times. Also, when backing out of driveway on a slant, rear emergency braking seems to sense the street and brakes are applied violently. This situation has also happened going into driveway on a slant for front emergency braking. Have informed the dealer several times of this problem and they say that Cadillac has not fix. Very distressing and dangerous for whip lash of adults and children.

We leased a Cadillac Lyriq on [XXX] for our Daughter [XXX] old) on [XXX] with my Son [XXX] ) while driving on [XXX] the car accelerator failed and my daughter pulled over. My wife received a text message from Onstar which said service the drive train immediately. My daughter pulled over and called me and said the car wasnt working and it was smoking. I told her to get out and call 911. This was a two day old car which during the course of normal driving stopped working and began to smoke, then a few minutes later was on fire. Thank God the doors were able to be opened and my kids got out safely. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have had two incidents with the automatic braking system occur in a short period of time. The Lyriq is not a car that I drive very often so when the incidents occurred in the last 2 of the 3 times of driving the car it makes me scared to drive the car again. The first incident occurred while driving at approximately 35 mph. The road I was on had 4 lanes with a turn lane in the middle dividing the 4 lanes with 2 lanes on each side of the turn lane. The road carries moderately heavy traffic as it has many businesses (fast food restaurants, strip malls, etc.) I was driving in the left lane when a truck in the on coming traffic entered the middle turn lane and a vehicle ahead of me entered the lane to the right of me. Neither vehicle crossed the line of the lane I was in. This is normal traffic for the type of road I was on. I know there have been reports of rain interfering with sensors in the past, but this day was clear. My vehicle flashed a red collision warning and engaged the automatic braking system. This was scary as heck. It was very jarring to me and my passenger. Next incident I was parking along a curb. So this time I was driving under 10 mph. I was backing up and there was a hand rail along on a walkway on the curb. There was no way I would hit the railing as it was several feet from the roadway. There was no warning in my car when it engaged the automatic braking system. Even though I wasn’t traveling very fast it was very jarring and my neck was still hurting from the last incident when it engaged the automatic braking. When the car engages the automatic braking system it sounds as though it has hit something or someone has hit you. It’s very confusing. I reported previous incidents to my dealer and they said that the sensors were sensitive and they supposedly did some sort of fix, but frankly I’m concerned what could happen as these incidents have quite seriously been a pain in the neck for me.

Cruising at 65mph in moderate mixed traffic when vehicle began maximum braking with no action from me and no forward obstacles. Several following vehicles had to take drastic evasive action to avoid collision. Very lucky this resulted in no injury or damage. Could have been much, much worse.

Right rear taillight and brake light fail to light intermittently. This is a known defect on many other Lyriqs. When this failure occurs, the vehicle is not compliant with state laws regarding having working taillights and brake lights, and could result in a moving violation ticket. Cadillac should be required to recall and repair/replace these lights.

See attached document for complaint.

The contact owns a 2024 Cadillac Lyriq. The contact stated that while driving under 35 MPH on several occasions, the brakes were independently activated. The TPMS warning light was illuminated intermittently. Additionally, the front passenger’s side tire was flat. The vehicle was taken to a dealer where it was diagnosed and determined that an undisclosed system software needed to be updated. The vehicle was repaired but the failure persisted. The manufacturer was notified of the failure. The failure mileage was approximately 7,000.

I was driving the vehicle and it stopped in the middle of the freeway. Another incident happened while Kane changing and another while exiting . All three incidents caused a extremely hard braking which felt like a collision.

Vehicle engage emergency stop in forward direction for no apparent reason. Leaving dead stop 2nd car at traffic signal. Huge problem as may cause rear end collision. I have disengaged all auto brake features. Had previously already disabled reverse auto braking feature. I was at a residential intersection. Single lane each direction with left turn lane. I was the 2nd vehicle in line. There was a crosswalk however there were no pedestrians, bicycles, etc. in the crosswalk or on any sidewalks of roadways. The left turn green arrow illuminated and the vehicle in front began turning. I began to follow and reached no more than 5-10 mph when "bang", the emergency stop engaged. I actually thought I hit a pole or object. Terrifying for my wife in the passenger seat also. The vehicle behind us was able to stop in time, this time. However, drivers do not expect the vehicle in front of them to begin moving the emergency brake for no reason. This is a dangerous defect which must be addressed.

It happened two times to me I was driving and I lost acceleration power. I put the car on Park and back to drive and it still didn't help the only way to get it to drive is to restart the car

Driving my car on the highway at speeds of about 65, and the charging port door suddenly opens. When I slow down then the door closes on it own. Seems like the housing for the door isnt made tight enough to stay closed during highway driving.

I purchased a brand new Cadillac Lyriq on July 1, 2024, and have encountered several severe issues that compromise the safety and reliability of the vehicle: 1.Display Failure: The display frequently flickers, flashes, and sometimes completely blacks out, causing the loss of critical information such as speed, backup camera, navigation, and other vital systems. This makes the vehicle unsafe to drive, as it is impossible to monitor speed and other essential functions necessary for safe operation. 2.Battery Overheating During DC Fast Charging: The vehicle’s battery consistently overheats during DC fast charging sessions, causing the charge rate to drop significantly (from ~190 kW down to 14-20 kW). This overheating issue not only drastically extends charging times but also raises serious safety concerns, particularly during long road trips in hot weather. The vehicle has repeatedly experienced these issues, making it unreliable for long-distance travel. 3.Charger Overheating and Instability During Home AC Charging: The home AC charger provided with the vehicle becomes excessively hot while charging the Lyriq. Additionally, the charging rate fluctuates erratically between 0-3 kW, further complicating the charging process. This overheating of the charger at home raises concerns about the safety of parking or charging the vehicle in my garage, as it may pose a fire risk. These issues have been reported to my dealership, who have attempted repairs without success. The problems persist, and the vehicle remains unsafe and unreliable for my family’s needs. I am deeply concerned about the potential for these issues to lead to more severe safety incidents if not addressed promptly.

When approaching a red light at 5-10mph, I engaged the brakes, but the brakes did not work and the automatic breaking didn't work either, leading me to rear end the car in front of me. There were no prior warnings lights or notices, and the breaks were working properly before and after the accident. The car was towed to the dealership for inspection, but they could not find anything wrong and have contacted GM for further inspection.

Car has a automatic back up braking system. The car will brake hard to stop vehicle if there is an object behind it. In this case, the car was braking when there was no object behind it. This happen continously while I was trying to back out of a parking space. I could only drive forward. Finally, after a few attempts to back out of the parking space, I was able to drive in reverse. After I was able to drive forward, I tested the the car drove to a location where there wasn't anything behind me. I put the car in reverse and it did it again automatically hard braked and stopped the vehicle. I waited then tried it again and I didn't have the problem anymore. I took the car to the Cadillac Dealer. I was told there have been others who have had this same issue. Furthermore, I was told they can't fix it. Perhaps the feature can be turned off I was told. I don't see where it can be turned off. The feature is a good safety feature if works when it should. Meaning, when there is truly an object behind the car. That's my complaint This was a scary episode.

The steering wheels sometimes don’t control the wheel and it is wobble.

I was driving the car on the turnpike and out of nowhere the rear collision system went offline and the automatic breaking was triggered while I was going 70 mph in rush hour. The brakes started to smoke and smell and the the warning of ‘breaks overheating. do not drive. call service’ happened. I proceeded to narrowly avoid many cars on the road by having to cross three lanes of traffic over to the shoulder and the car was fully smoking, I quickly turned it off I got out and stepped away. After some time when I felt safe returning to the vehicle I turned it back on and was still showing breaks were overheated message and then was forced to get the car towed and take an Uber home. The vehicle is only 2 months old with ~3300 miles on it. The vehicle is currently sitting at the closest dealership to the event and they are unable to work on it due to a lack of EV service provided there and they told me they are unable to have it moved to the dealership I purchased it at.

The back up lights when in reverse at night are inadequate to safely back the vehicle up. This is true whether one is using the rear window and rearview mirrors or one is using the back up camera. No more than 10 feet of area behind the vehicle can be seen by using these lights.

As I approached a stop sign and hit the brake the car did not stop. I pounded on the brake but there was no response at all; it just coasted forward. The car continued to move and hit the car in front of me stopped at the stop sign. That car, a Nissan Rogue, had no damage. I was barely moving but the plastic sheet in the front of the Lyriq was cracked.

The contact owns a 2024 Cadillac Lyriq. The contact stated while driving at approximately 3 MPH as she was entering her garage to park the vehicle, she depressed the brake pedal, however, the vehicle continued forward and crashed into a tool chest located at the back of the garage wall. The contact stated that the front of the grill and the front bumper were damaged and had to be replaced. The contact stated no warning light was illuminated. The contact stated that failure reoccurred when she was parking the vehicle in a parking lot. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the ABS system had failed and caused a loss of braking ability. The contact was advised by the dealer that the failure was related to NHTSA Campaign Number: 24V589000 (Service Brakes, Hydraulic). The contact had the recall completed at that time. The manufacturer was informed of the failure. The failure mileage was 3,000.

There was “Brake System Failure” message on the EV’s digital display. It happened 3 times in less than a month. When it happened, I had to apply the break very hard. Otherwise, the car would not stop completely and would not hit the car in front. Top speed is limited 43 mph so I could not drive it on freeway.

The automatic collision system braking is engaging when the vehicle is in reverse and while it is raining. This occurs multiple times while trying to back the vehicle up during rain. This is dangerous for the passengers since they are abruptly thrown backwards without warning. The vehicle must be placed in "park" and then "reverse" multiple times until the collision braking stops malfunctioning.

The contact owns a 2024 Cadillac Lyric. The contact stated that the brakes erroneously activated while attempting to reverse. The contact stated that the failure occurred only while it was raining. There were no warning lights illuminated. The vehicle was taken to the dealer, and it was suggested to deactivate the Back Over Prevention and Cross Traffic Alerts while attempting to reverse. The vehicle had not been diagnosed or repaired. The manufacturer was made aware of the failure by the dealer. The failure mileage was 145.

While driving at night, my headlights will randomly aim down. Can’t see the road ahead. When high beams are activated, they blast the front of the car. Cannot see anything down the road.

The vehicle initially had a windshield manufacturing defect according to Cadillac Service Center which allowed plenty of water to go inside the vehicle during heavy rain. After the vehicle was serviced weeks later I was driving and the digital dashboard when completely yellow and red. At the same time the automatic brakes activated and I almost got rear ended. They serviced the car again after being tow trucked and “couldn’t” determine the cause of the dashboard incident shown on the pictures.

The auto leveling lights drift during driving. On staff up, the headlights will point up and down, then self level. However, for the past week, the right headlight drifts down towards the road and the left headlight will drift upwards after about 20-30 minutes of driving. The downward drifting headlight only illuminates about 1 car length ahead while the upward drifting headlight will point towards overhead street signs. This causes reduced visibility with increased flare and reduced headlight throw at the same time. It also is dangerous to incoming traffic since the left headlight ends up drifting upward to produce a throw similar to a high beam, even though the high beams are off. The only way to get the lights to re-level is to shut off the vehicle and restart. Even after this, the lights will only be at the correct level for about 20-30 minutes as they start to drift in opposite vertical directions while driving. There have been multiple reports of similar cases on forums discussing the Cadillac Lyriq. Since the problem only occurs noticeably after 20-30 of night driving, the dealer has stated they can not reproduce it while in their possession. There are no warning messages or codes displayed.

Within two month the Lithium ion battery failed twice. and the car was not derivable. It had to bet towed to the dealer.

Without warning and while driving this vehicle on expressway, I've received the following notifications several times: "Brake Failure" (car brakes on its own); "Service Stability and Auto Hold"; and "High Voltage" and Battery. Brakes, speed, steering, parking systems and camera do not work properly. Car's capacity to drive vehicle safely is reduced significantly - speed to drive car is immediately reduced and is limited without warning. Car shakes passengers violently (whiplash) when it believes there are people or objects in its path when there is nothing there and does not work properly when pedestrians are around the vehicle. During the incidents both my safety and other drivers safety are at risk - I am afraid to drive this vehicle although the dealership has indicated they have corrected the errors.Vehicle purchased 23 Oct - problems began around 2300 miles and have continued thru 4200 miles.

When approaching sunset, or when travelling under bridges, the dash dims excessively and is barely readable. I have to take my eyes off the road for extended periods of time to be able to see the information. The excessive dim does not reset itself, when the ambient lighting returns to normal, for a prolonged period of time. Complaints to the dealer service department, GM EV Concierge, and OnStar have not had any effect on resolving this. Tnis is an ongoing problem since delivery of the vehicle.

There is a problem with the dashboard lighting. It is very dim and hard to read the dash to choose and view options and screen in general. I noticed this the day I picked up the new car. The dealer said there was nothing he could do. I contacted Cadillac and was told to go back to dealer and have him make a TAC call with GM for adjustment. They did this and said it met there specs. This is a very dangerous safety issue as when you are driving you spend to much time trying to see dashboard for adjustments and you can’t keep your eye on the road. I filed a complaint with Cadillac Customer Assistance, case # [XXX] and nothing is getting done about the problem. I’ve talked with several Lyric owners with the same problem and I see online a lot of customers complaining. I’m hoping you can get involved and get Cadillac to resolve this problem for myself and many other owners. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The car has 7300 Miles on it and it has an electrical Battery error that it can not start Also multiple soft ware errors the screen turns off while driving and assist control errors

Unable to see behind the vehicle in the dark. There is no backup camera image at night, screen remains black.

The contact owns a 2024 Cadillac Lyriq. The contact stated that while reversing from the driveway, the brake pedal was applied without driver input. The contact stated that the vehicle detected an unknown object, causing the brakes to be applied, but the contact determined that there was no object behind the vehicle. While driving at 50–60 MPH, the brakes were applied without application. There were unknown warning lights illuminated. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure. The computer was reset. The vehicle was not repaired. The manufacturer was contacted, but further assistance was not provided. The failure mileage was approximately 100.

Backup camera is black with lines when shifting in reverse. Unable to see to backup and almost hit someone walking behind me

The instrument cluster display is too dim to see, making it unsafe to drive

After dark, the rear camera is inactive. Also after dark, sometimes the backup lights do not come on in reverse. According to [XXX] , this is due to a defect with the rear electrical harness because an active license plate light circuit interferes with the camera and backup lights circuits.

The headlamps in the Cadillac Lyriq are supposed to be self leveling, maintaining a consistent throw throughout a drive. My left headlamp droops significantly after 10-15 minutes of driving, failing to throw its beam more than 15 feet ahead. This poses a a safety risk because it decreases my ability to see pedestrians or road hazards. This has not been reviewed by a Cadillac dealer yet because it is a known issue to which GM had no current solution. There are no warning signals that appears in the car’s screen. The two pictures below show the headlamps at start up and after 15 minutes of driving. The droop in the left lamp is noticeable. The pictures were taken from the same spot and at the same angle.

While driving the 12V battery system failed as well as the high voltage charging system. The vehicle lost traction control in the rain and was slipping on the road. The forward collision detection also intermittently goes out. If you are in one pedal driving mode and using adaptive cruise control when the forward collision detection goes out it will deactivate adaptive cruise control and apply enough regenerative breaking to rapidly slow the car. If the driver does not have their foot on the accelerator when this happens and you are in traffic it could cause an accident. The vehicle is not saving any diagnostic information regarding these failures and dealerships will not work the failures without diagnostic codes.

Headlights start dropping as car is driven. Every 10 to 15 miles must pull car over and restart as you can not see further than a car’s length in front of you. Cycle car off and then back on the headlights return to normal for another 10 miles. Also seems that some of the individual lamps start pointing upward blinding oncoming drives even with most of the lamps are pointing down in front of the less than a cars length. Seems the headlights are making adjustments be are not correct until you do a power cycle.

What component or system failed or malfunctioned, and is it available for inspection upon request? Multiple components of our driver assistance software have failed, beyond what we can check in the fields above. Most recently, we have experienced two major failures. The first failure occurred when the car triggered the emergency parking brake on its own while we were driving in traffic at 30 mph. We narrowly avoided being rear ended. This is the incident I've detailed in the fields below. The second failure occurred when the adaptive cruise control failed to brake as we approached gridlock traffic. We again narrowly avoided collision on multiple fronts. We were going approximately 45 mph with roughly 2000 miles on the car. We have the service records, but the selling dealer and Cadillac engineering claim these issues are now fixed. How was your safety or the safety of others put at risk? We were well within less than a car length of collision in both of the situations described above. This car is a large SUV, it would presumably cause significant damage to cars it hit. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. They verified failures and out-of-date software in our vehicle in this last service visit. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? This vehicle has been directly inspected by Cadillac engineering through our selling dealer. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? The warning lights we experienced included the warnings that the system had engaged and "service driver assist system." There was no warning when the adaptive cruise control failed.

Headlights on vehicle “droop” after driving 20 minutes or more. They start off okay and then become non existent l, pointing directly down toward the pavement in front of the vehicle and you can’t see more than 1 car length in front of you. You must turn the vehicle off and then back on to reset the headlights to drive. This is a huge safety issue for driving at night.

We encountered consistent loss of or erratic headlight operation. The behavior was that lighting would simply fail on one or both sides of the car, often along two-lane roads with curves in the road where it is critical to judge distance to oncoming traffic. Other times the lights would dim and wash out the ability to clearly see the road ahead. The dealer has replaced the headlights three times already. An associated lighting module was also replaced more than once. Note that this issue is still present so we are unable to use the vehicle now after dark.
