2024 Chevrolet Silverado Complaint Log

It was down pouring, I needed to pull over. The electronic buttons below the big display which included the HAZARD LIGHTS FAILED to respond. A symptom was the fan speed on the display would also not disappear. The dealership said maybe it was in the middle of an update. After she rebooted it worked again.

Complaint Description On Tuesday October 28th, 2025 while driving to work, my 2024 Chevy Silverado LTZ suddenly went into limp mode during normal driving. The truck would not go into reverse at all. I had to use OnStar to call a tow from my residence because the vehicle was not safe or able to be operated. The truck has been at the Chevrolet dealership since that day and as of today (November 7th) it still has not been repaired. The service department confirmed it is a failed transmission valve body. Research shows this is a recurring and known issue on many GM trucks and GM does not appear to have a permanent fix yet. Component/System that failed: Transmission Valve Body failure. Component is currently located at the GM dealership and is available for inspection. Safety Risk: This failure caused sudden limp mode, loss of power, and inability to reverse while in active traffic. This put my safety and potentially other drivers at risk due to sudden unexpected deceleration and inability to maneuver safely. Problem Confirmed: Yes. Confirmed by GM dealership service technicians. Inspection: The vehicle is currently at the GM dealership. No manufacturer field rep, insurance, or police inspection has occurred yet. Warnings / Codes Present: The failure occurred without prior early signs that morning. When it failed, OnStar diagnostics reported: P2732: Transmission System — “Engine and Transmission System not performing as expected.” P0700: Transmission Control Module requested Malfunction Indicator Lamp illumination. Emissions related DTC set in the Transmission Control Module. Both codes triggered at the time limp mode activated. Best Assessment: This appears to be an ongoing recurring GM transmission valve body issue affecting newer GM trucks. The failure caused a sudden loss of drive capability and is a safety hazard that requires NHTSA investigation.

The car seat anchor system is very poorly designed and extremely difficult to use. I just spent an hour trying to ensure the seats for our grandchildren are installed correctly. The upper anchors are poorly placed, difficult to access and do not inspire confidence the seats will be secure in the event of an accident. This is after I had to take the truck in for a warranty claim because the lower car seat anchor on the back seat passenger side was covered by factory upholstery and could not be used at all. It’s very frustrating when one attempts to comply with safety regulations but poor design inhibits the proper installation of car seats.

We have had four previously documented issues with the electrical, brake and engine in our truck. Today, we were advised by the dealer that the truck had been fixed, and a new ECM had been installed. They advised they drove the truck for 100 miles and there were no issues. We picked the truck up and on the way home, while on the highway, the truck went into low power mode, the brakes went out, the check engine light and slip light came on. The dash began flashing detection warning lights (see attached photos): Brake system failure 62 MPH top speed, Service steering column lock, Reduced Acceleration drive with care, Service ESC, Service traction control. We immediately turned around and went back to the dealership and showed them what was going on. They took photographs and had the technician come out to look at the vehicle. He looked at the lights and codes and admitted he does not know what is going on. The service manager said that the company representative was coming tomorrow (10/21/25) and that he was going to speak with him and recommend a buyback. We left the truck with the dealer and were given a loaner car. This is the 5th incident with the same issues.

8 Speed Transmission without any warning, started shaking and clunking and slipping while doing 55mph in traffic causing sudden loss of momentum. 8 speed transmission failure. Dealership says bad transmission control module and won’t inspect internal components. Chevy is still playing games with people with their defective 8 speed transmissions. They have not fixed all of their previous problems

2024 Chvrolet 3.0 Diesel is losing oil at 3k miles on every oil change. DTC P06DD , dealership did an oil consumption test, they have determined there is signifcant oil loss after every oil change after 3k miles. Truck is at 71k miles. Engine power loss while driving, check engine light on, drove straight to the dealership.

Truck did not have reverse. Service engine came on after going forward and possible loud shudder like going over a pot hole. Not sure if it was a pot hole or transmission. Dealer fixed the valve body in Transmission after 1 week.

For the first time I purchased a brand new vehicle off a dealership lot…What a mistake. While the dealership itself was an awful experience I thought it was worth it for a Chevy Silverado. After all my previous one was so reliable. WRONG. The first issue I found was I was unable to shift into reverse to back out of the driveway of a fire station I volunteer at. After driving forward a couple times and shutting the vehicle off and shifting multiple times I had to be towed out in reverse. I was able to drive home but the transmissions slipped once and the vehicle slowed abruptly. The check engine light was now on. I dropped the vehicle off at the dealership over the weekend and on Monday they called and informed me the 2024 Silverado misfired once and nothing was wrong with the transmission. There was nothing they could do. About two months later I was driving to work as a career firefighter/paramedic when my vehicles check engine light came on and a message informed me that I was in “reduced acceleration mode”. I slowly and carefully made my way to work and brought the truck to the dealership after my shift. The check engine light was now on again. They informed me later that day that I had a faulty valve body in my transmission. They “unfortunately” could not give me a completion date on my repair as they had no ETA for the replacement part. It appears the part is in high demand. This makes sense as a quick google search shows this is a widely known issue with the 10 speed transmission. So far I have been unable to get a rental vehicle between the dealership and GM. Aside from my house my 2024 Silverado is the largest purchase of my life. And at 15,000 miles I am without it for the foreseeable future. As a first responder the communities I serve depend on me to respond from home at any hour. My family and I are living in a DIY renovation while also starting a farm business. I need a dependable vehicle and regret spending $53,000 on a new vehicle. I have more to say.

I have a 2024 Silverado 1500 Z71. I purchased new, within the first month I started experiencing issues related to the fuel. Stalling, dying, missing at idle and failing to start. I’ve reported it to the dealerships, with the same response unable to duplicate. Sept 22, 2025 I was driving alone rounding a curve in the road when my vehicle lost complete power causing me to loose control crashing into trees. I was unharmed physically, but mentally this hurt. To know this all could have been avoided had Chevy customer service or the dealerships listen and looked at the dtc that were clearly shown. P3187 fuel pump pressure performance low pressure. Stated failed since last cleared. Dealership did not acknowledge or discuss with me this dtc. Instead they gave me a multi point inspection stating unable to duplicate. There negligence caused me to wreck

07/28/2025 10:35am, We had just pulled onto an Interstate ramp and the engine powered down and the dashboard began flashing errors, service engine soon light came on. The following errors were displayed: Reduce speed to 62 mph, brake system failure, Service traction control, Service ESC, Service steering column lock, Trailer brakes disabled service required. I had no brakes and had to pump them to get stopped. I was able to pull to the side of the road and shut off the engine. I called dealer and reported issue as this occurred last Tuesday. They advised to bring the vehicle in at 0800 tomorrow. I restarted the vehicle and system reset and I was able to continue. At 12:58pm, I pulled off the interstate ramp onto a county road and the engine powered down again and displayed the same errors. The brakes did not fail this time and I was able to get home.

On Tuesday we pulled out into traffic and the truck shuddered and I heard a pop. The air conditioner went out and then a plethora of warnings along with the service engine light popped up on the dash. The brakes stopped working and the truck went into a low idle almost causing the vehicle behind us to rear end us. Error messages were as follows: Brake failure do not go above 62mph, trailer brake failure, steering column needs serviced, service ecs and several others. I was able to get the vehicle back home and called for service at Green Chevy in Peoria, IL I was able to shut the vehicle off and restart it and all error codes were gone. I spoke with the dealer and took it to them. They advised it was a module issue and would reprogram it. It took 2 days and my vehicle is back.

Vehicle: 2024 Chevrolet Silverado 1500 High Country Engine: 6.2L L87 V8 Recall: N252494001 – L87 Engine Loss of Propulsion I am submitting this complaint to report a serious safety defect involving my 2024 Chevrolet Silverado 1500 High Country related to NHTSA Safety Recall N252494001 (L87 Engine – Loss of Propulsion). My vehicle experienced a sudden engine failure consistent with the conditions described in the recall, resulting in loss of propulsion. Due to this failure, General Motors authorized a full engine replacement at an authorized GMC dealership. After the engine replacement was completed, the replacement engine also failed in the same manner as the original engine, again resulting in loss of propulsion. This second failure occurred despite the vehicle being repaired according to General Motors’ recall procedures and specifications. Loss of propulsion creates a significant safety risk, especially while driving at highway speeds or in traffic, as it can lead to sudden power loss without warning and increases the risk of a crash. Despite the replacement engine failing in the same way as the original recalled engine, General Motors is now refusing to replace the second failed engine or provide a permanent remedy. As a result, my vehicle remains unsafe to operate and unresolved under the existing safety recall. I am concerned that the recall remedy is inadequate and that replacement engines may also contain the same defect, creating an ongoing safety hazard. I am requesting that NHTSA review this matter to determine whether the recall repair is effective and whether additional corrective action is necessary to protect vehicle owners.

Experience hard shifting into park from a stopped position a week or more prior to incident. While driving, several hard shifts were experienced which resulted in the vehicle unable to surpass 30 MPH. CEL illuminated displaying codes: P0747 and P0700. Suspected transmission Valve Body issue. Vehicle was towed to dealership that it was purchased from.

DEF System will count miles down saying it is going to put you into limp mode while towing, when there is 3/4 plus DEF fluid in the tank. This caused me several times speed slow downs under 65 to try to make it to a safe place to add under 2 gallons to fill a 5 plus gallon tank on 70 to 80 mph highways a few times at dusk and night with limited off off travel lane access! This is telling you it will put your vehicle in limp mode! Again causing a dangerous situation! I very much feared for my well-being along a dark road with cars going 70 plus while I was trying to add DEF to a 3/4 full tank only taking around 2 gallons!!

There is no sound from the entertainment system, this happens randomly about once a week. The Safty concern is that when this happens there is no sound for anything including directionals, other warnings and this can cause a Safty issue. The only way to have the system work again is to shut the vehicle off for ten minutes and restart. My vehicle has had the software updated at the dealership about every three months since I purchased it, and to no avail.

We took our vehicle to Weber Chevrolet in Granite City, Il on June 26 for an oil change. My husband and I purchased the vehicle on [XXX] from this dealership. We asked if they could put a heavier oil in the vehicle due to this being as one of the remedial fixes for the recall. The service department manager informed us that they would not be able to do this due to it voiding our warranty. They could not give a general answer as to when they will address the recall. My husband and I have safety concerns about taking this vehicle cross country for a family vacation at the end of July. We have decided to trade the vehicle in for a different model due to the uncertainty of the recall. Appallingly, no dealership, including the Chevy dealership we bought it from , is willing to take our 9 month old truck as a trade. We were informed by three separate dealerships that the car is basically worthless and they are not willing to have it sit on their lots depreciating until the recall is complete. It is completely unacceptable that we, as consumers, are stuck with a vehicle that has a potential safety risk. The car has already depreciated by $10,000 according to Kelly Blue Book. We have filed a complaint with the BBB, Illinois States Attorney Office, and with General Motors. General Motors informed me on July 2 that they will not address the recall until an issue occurs. If an issue occurs then they will address it at that time. Furthermore , they are not willing to buy the vehicle back, attempt to see if the engine is fine, nor willing to allow us to trade for another GMC vehicle. We are at a loss as far as our safety, loss of investment, and lack of any help from General Motors. I am adding screen shots of my communication with the general manager from Weber Chevrolet, jimmy Mckechan. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Component/System Failed: Power Train – specifically, the #6 lifter failed and is available for inspection upon request. Safety Risk: The failure caused noticeable engine misfiring, loss of power, and abnormal ticking sounds, which could potentially lead to engine stalling while driving. This creates a serious safety risk, especially during highway driving or merging situations. Confirmation of Problem: The issue was confirmed by a certified GM dealership technician, who diagnosed the failure of the #6 lifter. They advised that the lifter and potentially the camshaft need replacement. Inspection: The vehicle has been inspected by the dealership service department. No inspection has been conducted by police or insurance at this time. Warning Signs: Prior to failure, there were no warning lamps. However, the vehicle began exhibiting a noticeable ticking noise followed by rough idling and reduced performance approximately 71,000 miles.

6.2 L engine around 7500 miles engine light came on, it was slow to startup, would shutter during idel. Driving home on the highway the truck turned off cruise control and front impact warning then it came back on about 5 miles down the road. At the same time the truck was shaking and shuttering. Took it into the shop the next day and so far is having at least one maybe 2 cylinders misfiring. Also, since I bought it the axle locks keep saying to service them, take the truck to the dealership and they can't find anything wrong with them. The only way to get the indicator to stop dinging incessantly is to active the axle locks and deactivate them and that will make it stop dinging for about a week.

On 7 or 8 occasions while navigating parking lots/driveway turnaround, i bumped the resume switch on the steering wheel and the truck took off accelerating rapidly from 2-4 mph speed until I disengaged with the brake. Someone with slower reactions or unaware of what is going on is going to get hurt by this. I believe it's tied to collision avoidance system and the adaptive cruise control mode. This system will allow cruise to stay engaged even as it slows you to a halt in, e.g. a rush hour slowdown, but if it slows you to some speed just greater than zero, and the traffic ahead speeds up, it will speed back up to the cruise setting. Similarly, when cruise is disengaged by brake action, but there is still a stored value in cruise control, if you accidentally hit resume at slow speeds the logic is treating it like a traffic situation. So the old 20 or 25mph minimum engagement speed no longer applies. As for why I inadvertently hit resume, it has to do with the raised momentary rocker switch at the 9 oclock position on the steering wheel. If you make a turn with your palm against steering wheel. For example, on a left turn, if the wheel is turning counterclockwise and your left palm is in the 9 o'clock position, it can rub against the raised cruise control rocker triggering the resume function, and off she will go! A flush or recessed button/switch would have been a better choice here. At this point, a software change would be the best solution to ignore the resume function below a certain speed.

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, there was an abnormal burning odor entering the cabin of the vehicle, and the rear windshield shattered, with white smoke entering the vehicle. The transmission and engine warning lights were illuminated. In addition, several unknown messages were displayed on the instrument panel. The contact pulled over to the shoulder of the road and the vehicle was towed to a local dealer for further investigation. Prior to the failure, the vehicle was taken to the same local dealer where the OS Sensor was replaced. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 23,000.

Engine was making noise and ultimately stopped responding when I would push the gas, leaving me stranded on the side of the road. Luckily, I was able to get the vehicle off the road in time to not cause an accident. The vehicle could have stalled and seized up in the middle of the highway. This problem has been confirmed by the dealer in the attached work order invoices. It has not been inspected by anyone other than the Mountain Chevrolet dealership, to my knowledge. The dealership has the vehicle running again, but is not able to confirm if the 'new' engine in my vehicle is the one address the recall issue, reference number N252494000. Additionally, this vehicle broke down again two months later for a related issue per the additional service invoice attached. For all of these, GM has not been willing to pay for the full value of the rentals for each service, totaling over 60 days without my vehicle. I've requested this through the GM Customer Care to no avail. I would also like to receive confirmation that the 'repaired' engine in my vehicle resolves this open recall concern. I've been stranded on the side of the road twice now with this newer vehicle and would love some assurance from them. At a minimum I want GM to pay for the full value of the rental cars. For the record, I also requested GM buy-back the vehicle which they have rejected my request. Any help you can provide is appreciated. Thank you.

I purchased the Curt Triflex Next Trailer Brake Controller GM Part # 19435732 ( Although may be sold through several part #s) from Jim Norton Chevrolet as this is a GM recommended part through the GM parts catalog and is plug and play with included wiring harness making simple no wire splicing connection. The brake controller we need to tow or travel trailer it worked great for about a month maybe two , then I went to hook up our trailer and the brake controller would not function. So I had a electrician trouble shoot the power and all that checked out good. I contacted CURT for a warranty claim and they stated this is a known issue and they are sending me a new one and I did respond that's spooky what if I was towing and it stops controlling. this could lead to a serious safety issue. I unplugged and it and plugged back in and it started working then stopped again before the next weekend to pull my trailer. again Curt stated via email this is a known issue and sending me a new one when they are in stock , but I had not heard this until I contacted them for warranty claim and still have not received a replacement.

There is a safety recall on my truck and dealer wont take it in to address the issue. I have been trying for months and they say that they are waiting for guidance from GM. We don't feel safe driving the truck. Asked for GM to buy it back and they denied, told me to find another GM service center. I tried another and they said the same thing. I'm running in circles and shouldn't be forced to drive an unsafe truck that is ~1 year old.

When in Normal Drive mode, an unexpected or accidental bump of the Transmission T-Handle shifter between the seats towards rear of vehicle while at a stop sign or parking lot, etc. will "Lock The Transmission in Low Gear 1 out of 10 available gears". If one pulls out into traffic without noticing this event, the engine will approach redline without shifting into the next gear until the situation is acknowledged and the T-Handle is one again pulled back to reset it into automatic drive mode. This is frustrating and potentially dangerous if the situation is not recognized quickly. I suppose engine damage could be at risk. There is "No save the engine by automatically selecting the next gear if this condition happens. There is also no lockout requiring the T-Handle Shift Button on the side requiring to be pushed to acknowledge the desire to set this mode". I tested similar settings on Honda Pilot and it DOES UPSHIFT even if in this manual mode to protect engine and occupants from this difficult situation. I personally will no longer allow any others to drive my truck until this situation is remedied. It appears to be dangerous to me and my truck for those who have no idea this can occur. Please try it for yourself. Vehicle must be similar to 2024 Silverado High Country w T-Handle shifter between the seats. My hope is an over the air update can remedy this situation.

Valve body needs to be replaced. The truck is still under warranty. I have taken it to the dealership, they ordered the part and told me it was safe to drive in limp mode. I've since been waiting a month for the part to come in without a replacement vehicle. I can't drive to work and am losing quite a bit of business. There is a valve body in stock 97 miles away and GM will not ship it to my local dealer or help me in any way. The truck will not make it 97 miles for the repair. The check engine light stays on for a few days and goes off. I can only drive about 10 miles before it goes into limp mode and the dash will tell me I have reduced acceleration and to drive safely. As far as the safety of me and others UNKNOWN. The dealer has confirmed there is an issue but insists I continue to drive it even though I'm damaging the transmission.

Driving home, vehicle jolted, came to stop. Engine making metallic noise and would not start. Had to have vehicle towed to dealership. Dealership confirmed engine blew due to internal failure.

My Silverado has what seems to be a known issue with recent model Silverados which is a broken/blown valve body at the transmission. The week of the failure, my truck began having rough shifting from first to second gear first thing in the morning, but would be fine after that. Two days later this progressed to all of the gears and nearly stranded me and my kids on the interstate due to not being able to maintain speed. I got the truck to the dealership where they looked up diagnosis code and told me it was the valve body and it would require replacing. Unfortunately, the part is on national backorder with unknown delivery time. Looking online, it seems this is a known issue and parts seems to be months (6+) behind. I am stuck paying for a rental car that GM says I will get reimbursed for, but we will see. To complete the questions above, I did not notice any warning lights or notices until it failed.

Pulled into parking lot and went into a store. Upon leaving I noticed the vehicle would not back up when placed into reverse gear. The engine would rev but, no movement. I pushed the vehicle backwards and then restarted it. The vehicle would move forward. I stopped and attempted to try the reverse gear a few more times with no luck. As I started driving on the main roadway toward the GM dealership, the vehicle upshifted once and then displayed a warning along with e check engine light. Once at the dealership, they scanned the vehicle and confirmed a transmission issue. The vehicle never showed any symptoms prior to the failure.
