2023 Chevrolet Suburban Complaint Log

While driving on interstate XXX on 4/17/2026 my vehicle lost power I had to pull over on the shoulder thankfully I was able to do so. Restarted the vehicle for just a short bit and it said loss of engine oil pressure and died. would not restart. Ultimately had to be towed to a GM dealership Lynch Chevrolet in [XXX] . Was told the engine was shot and was covered under the safety recall. There was a recall on the motor I had brought it in to get rectified sept 2025.a heavier weight oil was added and filler cap replaced with 40 weight oil identification. . I just had an oil change the day before the incident on 4/16. What is concerning I'm worried about the long wait plus plus online blogs that indicate the engine failed numerous times even after replacement. I was told from the dealership that the engine was on back order and they cannot give me a time on when it's going to be available. But again I'm worried about this vehicle in general in moving forward or trying to anyway. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The sound in the vehicle goes silent and I'm not able to verify audibly that my turn signals are working or not. Which has led to a couple of near misses while in traffic. Power has been cycled and the call hang up botton has been depressed to soft reset the system and it still isn't working.

Vehicle mileage is approximately 45,000 miles. While driving in the rain the front windshield wipers stopped moving and were stuck in the down position. They would not activated with auto, manual, or wash commands. Rear wiper still functioned. This happened while driving down the interstate which resulted in having to slow my speed in heavy traffic and go out of driver position to see through a clear spot in the windshield, took exit 1 mile later and tried to find gas station, approximately 1 mile after exiting the wipers started to work again. This also happened at approximately 35,000 miles on the vehicle and the wipers did not work for multiple days, even with vehicle turned off for 12 hr period. Took to dealership and by that time they were working again and the dealership could not find anything wrong. Both instances happened on weekends so could not take directly to dealership while issue was present.

Car entertainment screen shot down, next day car completely dead, had to get a booster, now the engine sign is on, and car has only 33,000 miles on it

I purchased a 2023 Suburban on March 6, 2026 with 52,980 miles. I drove it home to my house and parked it. On March 7, 2026 about 6pm, I started the vehicle and heard a loud engine noise. I called the dealership and let them know about the noise. On March 9, 2026 I towed it back to the dealership. The vehicle has been in service since then and was told it needs an engine. Metal spun threw the engine block and has to replaced. I just purchased this vehicle and drove it one day.

The contact owns a 2023 Chevrolet Suburban. The contact stated that the engine and oil warning lights were displayed. The vehicle was taken to the local dealer, and the vehicle was diagnosed with engine failure. The vehicle was not repaired. The manufacturer was contacted and referred the contact to the NHTSA Hotline. The failure mileage was approximately 100,000.

Regarding a catastrophic engine failure involving my 2023 Chevrolet Suburban equipped with the 6.2L L87 engine. There is an active GM service bulletin that we never received from either Crabtree or GM. Vehicle details: • Purchased in North Carolina in 2024 • Approximately 4,000 miles at purchase (used, still under factory warranty) • Currently at approximately 60,000 miles • Within the 5yr/60k powertrain warranty at the time of failure Incident details: On Friday 2/20, the engine experienced a confirmed catastrophic failure while my wife was driving on the interstate at highway speed. The vehicle abruptly lost power, creating a significant safety hazard. She was able to maneuver to safety, but the situation presented a serious risk of injury. GM has since towed the vehicle and confirmed catastrophic engine failure. We have been provided a rental vehicle - not a comparable one either (they refuse to address that also). Given the safety exposure and warranty status, I am evaluating potential potential claims including breach of warranty, implied warranty of merchantability, and any product liability considerations. I am also interested in understanding leverage for buyback, diminished value, risk of serious injury to my wife, or extended warranty resolution. I have preserved documentation, service records, and a written account of the incident.

Sun Roof has leaked. The Sun roof leaked a considerable amount of water and it came through the head liner around the ceiling mounted control panel as well as the back of the car. This is the second time it has happened and I have been told it is not covered under warranty. Through online blogs and forums I have found that this is a common issue with 2021 and newer tahoes and suburbans. And that is a reoccurring problem that is commonly not fixed properly by the dealers This causes a safety and health issue as well as an unacceptable vehicle defect. 1.) From a safety standpoint, if I am driving down the highway and a large amount of water starts pouring out of the headliner on the driver it causes a major distraction that could lead to high speed accident. 2.) From a health issue, regular water leaks could lead to vehicle mold and water damage. I have children, if they become susceptible to the mold it could cause health issues for me or my children. 3.) The water that pours out of the ceiling lands on the dash electronics which could lead to more vehicle issues by damaging electronic controls. It is my opinion that this is a major vehicle defect and something should be done by the manufacturer to correct it. I have made a complaint to the Chevy Customer service under reference #890 780 85

Transmission, got a message stating the service transmission or won’t be able to shift. Took it in to the dealership was advised that car can shut down at any moment. As that what they have been seeing.

Engine rattles and noisy, now auto light and message board states "Add Engine Oil)

The lights flash high beam, low beam, high beam, low beam, while I’m driving. Nothing seems to keep them from doing that.

Sun roof exploded while driving. Temps were not extreme, there were no significant pressure changes. Sun roof had no prior damage. Looking online multiple people reported the sun roof exploding on 2023 tahoes and suburbans.

My 2023 Chevy Suburban High Country had the L87 Engine Loss of Propulsion (Related field action: See Special Coverage N252494003) recall performed on it and completed on August 15, 2025. Higher viscosity oil was put in. This was at approximately 55,000 miles. While driving on the highway at 60mph on December 29, 2025 the vehicle twice lost propulsion and indicated the vehicle needed to be restarted. I took it to a Chevy dealer to have looked at in early January 2026 and they could find no issues or codes. On January 31, 2026 while driving on the hwy at 75 miles per hour the vehicle started to rattle and it lost propulsion. The DIC indicatd "System Failure" and I had to pull off to the shoulder of the highway. The DIC repeated "System Failure" and that the vehicle needed to be restarted. The vehicle would not restart when attempting to press the brake and restart. This happened on a busy interstate and the safety and well being of my family inside was put at a risk that could have been avoided, likely if the engine would have been replaced in August of 2025. The temperature outside was in the single digits and there was no air pushing through the vehicle while we waited for a tow truck and another family member to pick us up off the highway. There was no warning lights or messages prior to this happening. The vehicle is currenlty undergoing diagnostic testing at a Chevy dealership. This happened at 69,000 miles. This is highly concerning that this could happen in a 95,000 dollar vehicle. This is absolutely a saftey risk. I'm lucky I was able to merge on the interstate in a vehicle that could not maintain the speed with traffic and pull off to the shoulder.

The drivers side, female end, of the seatbelt comes undone when cold. This is reproduced every single time it is cold for approximately 5 minutes of driving until the inside of the vehicle warms up. This happens with both primary divers of the vehicle. We took it to the dealership we bought it from but because there is not a current recall and they cannot reproduce the issue since our current temperature is in the 40s, they won’t replace it under warranty. No warning systems go on when this happens while driving.

OEM Running boards, non powered. It is available for inspection. The running boards are slippery evetime they are wet. Does not matter what shoes you have. I have slipped 4 times since owned the vehicle and even broke the interior panel of my driver side door in 2023 which lead to a$500 repair bill. My wife and I both slipped today (1/26/26) and bruised pretty bad. Kids have also slipped in the past. No, it was not inspected or reproduced but dealer did say its a common problem they see with the OEM running boards. No, it was not inspected by the dealer. No warning lamps since it is a non powered part.

The code that originally came up was P0300 a (Engine Misfire). I had this truck for one year and it says my fuel injector went bad so I’m getting the whole Tune Up done. I have the My Chevrolet app connected to my vehicle and it’s saying: the Engine/Transmission system needs service and the Emissions system! Mind you I e only had this vehicle for one year i bought it in February 2024 and it’s a 2023! I bought it from Lindsay Ford in Wheaton MD. I feel as though all this should not be happening in a matter of one year l believe I was sold a defective truck.

After just getting our vehicle back on 12/11/25 from our incident on 11/9/25 when my wife was driving at 70 MPH on the highway when the engine blew the first time. Approximately 1300 miles later and 15 days after we picked up the vehicle when I was merging onto the highway the vehicle had a sudden power loss and a smell that filled the cabin. We were able to drive to the next exit and while the vehicle was idling it sounded awful. The check engine light started to flash along with the TCS light and the collision warning lights. After getting to a parking lot when called OnStar to tow our vehicle to the closest dealer. I have not received any updates yet but it is very similar to what happened the first time when the engine needed replaced.

Following extensive research & uncovering the fact that there are several class action lawsuits underway calling out GM for not issuing a formal recall when they should have from the start, we've been forced to personally absorb significant costs tied to replacing our 2023 Suburban's Valve Body around the mid-December FY'25 timeframe. It's also been publicly stated that GM opted to "not release" an official recall for the 1500 series Suburban when they've already issued an official recall for the larger 2500 series equivalent, according to our local dealership. We've already filed an official "full credit request" with GM's complaints organization, but we're sensing our voice will likely remain unaddressed at this point unless proven otherwise. Additionally, this is the second purchased Suburban with a YukonXL, being our original purchase from many years back, but in short, we're going to transition away from GM vehicles long-term, assuming our "full credit request" remains ignored. In short & our local dealership totally agrees with our current stance, critical transmission components should not be failing at this point & especially with a newer Fy'23 Suburban, when behind the scenes GM opts to "not recall" saving the company north of 600M from many months back. Just terrible from so many perspectives, as disgruntled end-clients like myself suffer from forced irresponsible cost requirements.

I was driving to work last Wednesday, and I live on a hill. As I was driving, a "Brake failure" alert came over my dash and I lost all control of my brakes!!! I live right off of Main Street, and my options were only to go straight and into a house, or to turn onto Main Street and hope no one hits me or that I don't hit another vehicle. I turned and thankfully no one was coming. At the end of that street I was able to coast into an closed down gas station and park the vehicle. I called the dealership I had purchased this vehicle from 10 months prior, and they told me I had to use OnStar to have it towed to them. I did that, and they towed it to the dealership. The next day the dealership told me the cause of losing my brakes was due to a SOFTWARE UPDATE that was needed!!!!! They charged me $800 for the update & a battery that they said was not holding the charge, which I've never had an issue with. I had purchased an extended warranty with this vehicle and I was told it would be a bumper to bumper warranty AS IF I had purchased it new (it was 2 years old). The dealership said this was not a critical software update and was not covered under any warranty. I could have been KILLED or seriously injured or killed or hurt someone else due to my brakes going out due to a SOFTWARE UPDATE that was needed!! This is insane!

The contact owns a 2023 Chevrolet Suburban. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed with a failed coolant control valve. The contact was informed that the coolant control valve needed to be replaced. The vehicle was not repaired. In addition, the contact referenced a Special Coverage Program: N252508341, however the VIN was not included. The manufacturer was made aware of the failure but provided no assistance. The contact was advised to contact the NHTSA Hotline to report the failure. In addition, the contact was informed that the NHTSA could add the VIN to the special Coverage Program. The failure mileage was approximately 134,943.

Car shows ESC error message not detecting brake pads, and locking the wheel.

While driving a 2023 Chevrolet Suburban (VIN: [XXX] ), my [XXX] son was seated in the second-row center seat and was properly buckled in with the factory shoulder/lap belt. He turned around briefly to grab something from the back of the vehicle, and during that movement the seatbelt fully extended and then locked in the automatic locking mode. The retractor would not release tension afterward. The belt continued tightening around his torso, and no amount of slack could be pulled back out. The belt became so tight that he was unable to breathe comfortably or free himself, and the locking mechanism would not disengage even after the vehicle was stopped and turned off. The seatbelt remained fully cinched and would not retract or loosen under any circumstances. Because the belt created a serious entrapment hazard and my child could not safely be removed, I was forced to cut the seatbelt to free him. This appears to be a dangerous malfunction of the seatbelt retractor/locking system and presents a significant safety risk, especially for children who may shift or turn in their seats during normal use.

Since purchasing the car in March 2023, the battery has died 5-7 times. We contacted our dealer and they claimed nothing wrong and the battery was fine. We have contacted them about this issue and there is no fix. They performed an update in June 2025 which was supposed to fix it but it didn’t. The latest it has died is November 25. There was nothing left on for the battery to die. I have 4 children and it’s starting to get very cold outside. I live in a rural area with poor cell reception. I am worried I’ll be stranded somewhere with a new baby and 3 younger children.

My 2023 Chevrolet Suburban High Country (VIN: [XXX] ) suffered a sudden and dangerous engine failure while my wife was driving 70 mph on the interstate returning from our child’s sled hockey tournament in Ohio. The vehicle gave no warning lights, alerts, or diagnostic messages before the failure. While driving in the right lane, the vehicle began losing power and making a loud noise. My wife exited the highway and contacted OnStar, who told her the tow would take over an hour and only cover three miles to closest dealer, leaving her stranded in an unsafe area. She attempted to carefully reach a nearby dealership. During this attempt, the vehicle completely shut off and she lost all engine power. The vehicle lost all power making the final turn into the dealership coming to rest in the middle of oncoming traffic of a four lane road. The Suburban would not restart. A tow truck arrived and transported the vehicle to a dealership. When they arrived, the tow driver noticed smoke and a strong burning odor coming from the engine compartment and told her to move away from the vehicle because it could potentially catch fire. The vehicle was left in the lot with the hood open and positioned away from the building for safety. The dealership has determined the engine suffered a catastrophic failure and requires complete replacement. Multiple related components may also be affected. This occurred on a vehicle with only 54,000 miles that was purchased three months earlier. This incident created a serious safety risk for my wife, who was nearly stranded on an interstate and had to maneuver a powerless vehicle across several lanes of traffic. I am reporting this to NHTSA due to the sudden failure at highway speed, lack of warning, and potential fire hazard.

I was driving the vehicle and without warning it just stopped shut off and immediately shot an error code that there was a critical issue with the engine and that the oil pressure was low, and the vehicle would not start and was not drivable. It had to be towed to a dealership.

I went to get in my 2023 suburban this morning to travel to the gym. It started but it would not shift out of park. I looked down and noticed the check engine light was on, the ABS light was on, and the park brake light was on with a lock and wrench. I had no issues since I purchased it used in March 2025 and yesterday it was driving fine.

The contact owns a 2023 Chevrolet Suburban. The contact stated that while driving at 10 MPH, there was an abnormal rumbling sound coming from the engine, with the check engine and traction control warning lights illuminated. Due to the failure, the contact restarted the vehicle and drove to an independent mechanic. The mechanic performed a diagnostic test on the vehicle and discovered a misfire in cylinder #3. The mechanic replaced the cylinder #3 ignition coil; however, the failure persisted. The contact then had another independent mechanic at the same shop inspect the vehicle, and the mechanic diagnosed the vehicle with engine failure. Neither the dealer nor the manufacturer was notified of the failure. The vehicle was not repaired. The failure mileage was approximately 52,000.

2023 Chevy Suburban transmission control valve failures causing wheel lockup or deceleration causing the vehicle to be unsafe to operate. Chevrolet refuses to acknowledge.

When driving making a left or right hand turn my 2023 Suburban loose power and turns off and it is thrown in N and state to press start to restart my SUV. No codes are given to determine the issue. This has happen a handful of times. It has been taken into Chevy and they are unable to diagnose the problem. During the one visit they stated it was the battery and replace it and it has done it again. This is a very unsafe to drive the SUV as I'm afraid someone will rear end me and hurt me or someone else.

On star Telematics Control Module is not working.

Onstar module not working, 53000 miles on 23 Suburban. Will be taking it to the dealership this next week. No other issues except for that.

Transmission malfunction. This has appeared several times at highway speeds and low speeds. We have dad to limp along in the slow lane to exit ramp and take back roads to the nearest dealership. The current problem has been confirmed with error codes P0747. The dealership has scanned this vehicle and detected error codes in the past on two different occasions and found P176C in TCM on 08/01/23 and P17D6 on 10/24/24. Check engine light comes on with a screen prompt “Reduced Acceleration Drive with Care”. The transmission valve body has already been addressed once because of triggering limp mode.

I am driving a 2023 Suburban Z71, continually on and of of the engine light and "reduction in acceleration, drive with care" this truck has the same issue and same engine as the recall, but is not included. Yesterday i was almost t boned at an intersection because the vehicle would not develop enough power to get across a street at a stop sign. one of the scariest and near disastrous occurrences of my life. this truck is deadly

After restarting the vehicle, the vehicle operated normally. The contact stated that the failure had occurred on several occasions. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was not yet contacted.

What component or system failed or malfunctioned, and is it available for inspection upon request? - Initially, the vehicle began making loud 'clanking' sounds from the engine, which immediately affected the ability to drive the vehicle. Upon further inspection by a third-party mechanic, it was determined that the Crank Shaft had malfunctioned. This is a known recall for our vehicle type (model, year, engine), however, no recall notice has been received at this time. How was your safety or the safety of others put at risk? - The vehicle was slowing abruptly while in drive mode, potentially causing a vehicular accident. Has the problem been reproduced or confirmed by a dealer or independent service center? - Yes, we did not deliver the vehicle to a dealer, as no assistance was initially offered when we made an attempt to call and inquire. However, a third-party mechanic was able to determine the issue. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? - Not at this time, as the dealer we initially inquired with did not seem inclined to assist. We consulted with a third party. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? -No. Failure messages or icons came on after the engine failure began

Not sure the exact cause yet. But another big leak of coolant from the car. This is the 4th big problem with the same issue. I have been dealing with engine/radiator/coolant problems with this car since April 2024. It has been in the shop 2 separate times for 9 weeks total. With other visits in between. There is something wrong with this car.

Our Chevrolet suburban has 57,000 miles on it. We have started getting a check engine light and I’m getting code P1098 for the cooling control valve. This is a very common issue on these vehicles I’m noticing now. From what I’m reading in February of this year (2025) gm gave this issue an e code so these valves would no longer be covered pay the powertrain and they would now fall under emissions for a much shorter warranty coverage. This has been and ongoing issue since 2020. These valves are also commonly found to be on national back order causing long lead times and driving of the vehicles without properly functioning. GM knows these are and issue and shortening the warranty is not the fix. These vehicles weren’t bought with a short warranty and shouldn’t be able to be reduced to a short warranty.

Dealer attempting to sell 2023 Chevrolet Suburban with 6.2L engine and no corrective action under N252494000.

Its been over a month and the dealership is unable to remedy this defect. I also called GM and they said the recall in incomplete and its in the preliminary stage. We are concerned that this is a serious safety recall and GM will not offer alternative solutions in a reasonable time.

The contact owns a 2023 Chevrolet Suburban. The contact received notification of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was made aware of the issue and confirmed that parts were not yet available. The manufacturer was made aware of the issue and confirmed that parts were not yet available. The contact was dissatisfied with the manufacturer’s remedy for vehicles that pass the engine inspection. The contact had not experienced a failure. VIN tool confirms parts not available.

The contact owns a 2023 Chevrolet Suburban. The contact stated that while coming to a stop, the vehicle vibrated abnormally. Additionally, the contact stated that while driving at an undisclosed speed, the vehicle stalled with several unknown warning lights illuminated. The vehicle was able to be restarted. The vehicle was taken to the dealer, where it was diagnosed and determined that the cylinders and injectors had failed and needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 33,190.

I was driving down the road at roughly 30 mph when my fuel tank dropped. The front fuel tank strap fell off and the bolt was gone. The fuel tank drug on the road, which prompted me to stop driving. There are scrapes on the front of the fuel tank and the strap was bent. This is a huge safety concern because had the fuel tank cracked or fell off completely this could have caused a fire. Had we been traveling at higher speeds, this could have been a very serious accident. The potential for gasoline or diesel to ignite was absolutely present. It could cause a fire or even an explosion, potentially injuring occupants and causing damage to the vehicle. I was travelling with my kids and mom, so the risk of injury to multiple people was present. The manufacturers only response so far is that it was not an open recall issue so it is not covered. No warning lights came on when this happened.

Coolant control valve failed. Reduced engine power, and engine fan on high.

Coolant control valve went out and causing car to get hot and lose power. Service department said it’s on back order and it’s fine to drive it.

Check engine light came on Then : message saying power reduced. Then: Service transmission, unable to shift soon. While driving on the highway. Vehicle has been at dealership for a month with no idea on when parts will be available. They say they have no idea on when a valve body part will be available.

This vehicle shifts hard and was identified to have a transmission valve issue. It should be under the same recall that other Chevrolet vehicles have with same issue. On top of this, Chevrolet cannot keep up with demand for this part making only 500 per week. I’ve been told it may be 2 months before I have my vehicle back.

Engine need replaced because the common lifters problem in 5.3L engine. It happens at 41k and now at 100,00k. Dealer don’t want to admit this safety issue and need to be investigated this is not acceptable.

Lifters failed again for the second time. First time was at 41k miles fixed by dealer under warranty, it happened again today 05/02/2025 with 100k miles on the engine with ticking and cranking noises and being told it need an new engine. 5.3L suvs need to be investigated and be recalled for engine failure it is a common issue please help.

I’m filing this complaint regarding a serious safety concern with my 2023 Chevrolet Suburban. The vehicle is affected by NHTSA Recall 25V274 related to a potential defect in the crankshaft or connecting rods. GM has confirmed the recall, but there is currently no fix available, and dealerships are not equipped to inspect the engine to determine if it’s defective. This leaves us driving a vehicle with a known risk of sudden engine failure, especially at highway speeds or while towing. In addition, my vehicle is also experiencing a transmission issues and is expected to be in the shop for up to three months for repairs. The combination of an unresolved engine recall and a failing transmission makes this vehicle unsafe and unreliable. We are a family of six with four small children (two in car seats, two in boosters). We purchased this Suburban specifically for safety, towing capacity, and long-distance driving. Right now, we are left without a safe or functional vehicle. GM refuses to provide a comparable rental and has offered only $44/day, which doesn’t cover anything close to what we need. We’ve attempted to work through GM and our local dealership to resolve the issue, but we’ve been passed back and forth with no solution. I’m concerned that GM is knowingly allowing vehicles with unresolved safety defects to remain on the road with families inside them. I’m asking NHTSA to investigate the handling of this recall and the delays in the transmission repair that are putting families like mine at risk.
