Had a vehicle update for my 2023 Chevrolet silverado and now my onstar module is toast and no longer under warranty bc I have 37,000 miles. Many reports of this happening to 2023 models but no recalls for this. Why should I have to pay $1000. 00 for a part that is failing in many vehicles of the same year.

The rear park assist will randomly turn itself off. It happens while just driving down the road and also at times when backing up. This has been an ongoing issue since I took the truck in to get the chips installed for it to work.

The micro switch that tells the truck that it is in park is not working. So when the truck is put in park the display says vehicle not in park and dings. This started at only 48,000 miles intermittently but is doing so constantly now at 53,500 miles and I’m having to buy a part to replace it.

While driving at approximately 45 mph, the steering system suddenly failed without any warning. The steering wheel became extremely stiff and nearly impossible to turn, resulting in a sudden loss of control of the vehicle. I was unable to safely steer, especially when attempting to turn right, which nearly caused a crash. There were no warning lights, alerts, or prior symptoms before this failure. The issue occurred abruptly and without any indication, creating a serious and unexpected safety hazard. Due to the severity of the problem, the vehicle had to be towed and is unsafe to drive. This appears to be a failure of the electronic power steering (eps) system. A sudden loss of steering assist at driving speed presents a significant risk of injury or death to the driver, passengers, and others on the road. This is a critical safety issue that should be investigated immediately.

In 2024 there was a recall for the tailgate locking mechanism - we did not receive that recall - but the part went bad causing the battery to drain - and it had to be repaired. We had to pay for the service $500. 00 - we I asked the dealership about this recall they said it did not include my vehicle. But it was indeed that part that went bad. I lease the truck - I had every intention of purchasing after the lease - I am over the miles and was told it was out of warranty. I certainly would not complain about paying for it - but there was a recall last year for said part. Could some please reach out to me regarding this - thank you.

The contact owns a 2019 Chevrolet silverado. The contact stated while driving at an undisclosed speed, the steering wheel failed to steer in the intended direction. The service power steering warning light illuminated. The contact stated that, fortunately, the failure occurred while the contact was driving in the contact's residential driveway. The vehicle was taken to the dealer where it was diagnosed with a failed electrical ground strap. The contact was informed that the electrical ground strap needed to be replaced. The vehicle was repaired. The contact referenced a customer satisfaction program n25251590, however the contact was informed that the repair was not covered under the program. The manufacturer was made aware of the failure but provided no assistance. The contact was advised to contact the NHTSA hotline and report the failure. The failure mileage was approximately 60,000.

On 04/16/2026, while driving, vehicle received and completed a software/firmware ota update. A second update completion prompt was received while still in motion. Shortly after, while stopped at a traffic light, the auto-start/stop system re-engaged and the vehicle appeared to restart normally. Upon stopping to refuel, remote key fob auto-start failed to respond. Vehicle was started manually and driven to the next location. On arrival, remote key fob auto-start failed again. Used interior push-to-start — vehicle started but displayed an active check engine light. Connected vehicle app diagnostic scan of the engine and transmission system returned two warning flags requiring service: - transmission system — schedule service now - engine electrical system including charging and starting system — schedule service now all other scanned systems (air induction, fuel management, engine cooling, throttle control, ignition, variable valve timing, 4wd, displacement on demand) returned ok. Both faults appeared immediately following the ota update. Remote start failure at two consecutive locations and the check engine light activation are directly correlated in timing with the update applied on 04/16/2026. No fault codes have been pulled yet — dealership service appointment pending. This is not the first instance of an issue after updates are applied, between the infotainment system blacking out, rear camera or adas not functioning as well as sporadic crackling sound almost like electricity arcing in the engine compartment near the steering column.

I purchased a 2026 gm chevy silverado. At 500 miles all dash warning lights came on while driving, radio played static. I disconnected battery in order to reset the computer. At 1400 miles in the heat of south florida the air condition stopped working. After completing my drive 60 miles away with no ac I disconnected the battery to reset the computer. The ac started to work after this reset. I went to the dealer and they wanted me to leave the truck. They could not provide a loaner and the fact that this is my only vehicle I could not leave it. At 2000 miles the computer screen stated that there was an update. The computer would not update when I pressed start update. The screen then said unable to update conditions not met go to the dealer. I went back to the dealer and they said there is no update and they reset the computer. This is going to kill someone when they pull over on the highway because the christmass tree on the dash caused them to pull off the highway and a semi is going to kill their entire family when they are stoped on the side of the highway because gm cannot make a vehicle that works correctly. Please go after gm the company that stole your tax dollars when they went bankrupt.

Two grounding straps failed on my 2021 silverado trail boss lt. Gm has a recall for this exact problem under n252515590, model years 2019-2024. Apparently my VIN number is not associated with this recall, yet my dealer just did the recall repair. They said my truck did not qualify for the gm recall and I was forced to pay for the repair. The failing grounding straps caused my power steering to go out and my brake system and safety traffic sensors to fail as well. This was very dangerous as it would fail randomly while driving the truck. There were no warning signs or lights on the the truck to indicate any problems.

The contact owns a 2015 Chevrolet Silverado 1500. The contact remote started the vehicle and left the vehicle unattended for several minutes. When returning to the vehicle, the vehicle was on fire, and the window was shattered. The fire was coming from the rear window behind the driver's side, which melted all the plastic around the shattered glass. The contact notified the dealer. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 142,000.

My 2019 truck with 50k miles on it, broke down and nearly caused an accident. The safety recall for the wiring harness chafing was not assigned to my VIN. I had vehicle towed to find out my loss of power and 17 error codes were due to the wires rubbing due to improperly installed by the dealer per this NHTSA. I called the 1800 number for chevy and they told me my VIN wasn’t “picked” to be part of this recall. I asked why, my vehicle did exactly what recall said. They said sorry we can’t do anything. I could have died the way the truck acted. I need a complaint filed and assistance having the dealer add my VIN to this recall. Any assistance will be appreciated.

Telematics module failure. Causing loss of onstar, self driving feature, compass, navigation.

Vehicle power steering went out while driving as I almost crashed through the corner. My anti-skid light came on on the dash along with a message saying service power steering drive with care and a message saying service esc. Upon further investigation, it appears the ground strap connecting the frame to the passenger side wheel well is corroded camming electrical problems with the power steering, etc. Apparently my VIN number does not qualify for replacement on my 2019 truck even though it’s still in their warranty chevy should replace these straps for free. The dealer wants to charge $300 for a diagnostic fee in around $300 for another repair. However mine is under warranty, but I feel like I should not have to pay a diagnostic fee. It should be covered as a recall. I have attached pictures of the codes from the dealership computer.

I am submitting a formal safety complaint regarding an electrical system failure on my 2021 Chevrolet silverado with approximately 61,000 miles. I brought the vehicle to taylor grubaugh Chevrolet of waynesville after the check engine light illuminated. The dealership diagnosed a premature wiring harness failure caused by chafing. They also stated that this issue is known to affect multiple gm vehicles and is documented in technical service bulletin 21 na 149. Wiring harness failure presents a significant safety concern. A compromised harness can lead to erratic electrical behavior, reduced engine performance, stalling, or sudden loss of power while driving. With that the concern a possible vehicle malfunction or losing power in traffic came to light. The dealerships service department confirmed the problem, verified the wiring harness failure, & referenced the applicable gm technical bulletin. The vehicle was inspected by the authorized Chevrolet dealership. Gm declined to cover the repair. No police, insurance, or other third party inspections have been conducted. Despite acknowledging that this is a documented & recurring issue across gm models, the gm informed me that the repair would not be covered under warranty or recall. At only 61,000 miles, a wiring harness failure due to chafing is not consistent with normal wear & tear & instead suggests a premature defect. Given that this is a known and documented defect, I believe it should be recalled. After further research, I discovered that this issue is far from isolated. There are more than 1,500 complaints filed with the better business bureau and approximately 800 complaints submitted to NHTSA reporting the same or similar wiring harness failures across gm vehicles. The volume of complaints strongly suggests a widespread defect that may pose ongoing safety risks to consumers.

The contact owns a 2021 Chevrolet silverado1500. The contact stated while driving the vehicle he felt shuttering and noticed his automatic start does not start. The contact also experienced engine reduced power issues, preceded by a warning sign on the dashboard stating "engine power is reduced" while driving. Additionally, the contact noticed a significant loss of mileage per gallon and a loss of oil. The contact noticed a check engine light on, which had codes that had a crankshaft and cam shaft sensors that are not operating properly, which the vehicle cannot be inspected due to the failure. The vehicle was taken to a dealer where it was diagnosed to need a new timing chain to control on the cams and crankshaft. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 110,000.

The contact owns a 2022 Chevrolet Silverado 1500. The contact stated that while driving at 45 mph, the tailgate unintendedly opened unintentionally while there were items stored in the trunk. Upon coming to a stop at the red light, another driver alerted the contact that the tailgate was open. The contact pulled over to the side of the road, and the tailgate was closed. The vehicle was driven to the residence and was parked and turned off; however, the contact became aware that the tailgate had opened while the vehicle was turned off. The contact disconnected the tailgate switch to prevent the battery from draining. The vehicle was taken to the dealer, where it was diagnosed, and determined that the tailgate switch had failed and needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not included in gm campaign number: n232426400. The failure mileage was approximately 63,000.

I am writing to report a serious safety concern involving my 2024 Chevrolet silverado that resulted in a child being locked inside the vehicle with the key fob present inside the car. On March 25 2026, after parking and turning off the vehicle, I exited the driver’s seat with my key fob inside my purse, which remained in the front of the vehicle. I then walked around to remove my daughter from the back seat. During that time, she climbed into the front seat and pressed the interior door lock button, locking all doors. My daughter has autism and is not able to follow instructions or unlock the vehicle on command. As a result, she was locked inside the vehicle with the key fob present inside, and I was unable to gain access from the outside. The vehicle did not prevent the lock from engaging, nor did it allow me to open the door despite the key being inside the vehicle. This situation required emergency assistance (911) to safely remove her from the vehicle. I understand that many vehicles have “lockout prevention” features; however, in this case, the system did not account for a vulnerable occupant inside the vehicle. Allowing the vehicle to be locked from the interior while the key fob is inside—and without any external override—creates a significant child safety risk. I am requesting that Chevrolet review this design behavior as a potential safety issue, specifically: - why the vehicle allows interior locking when a key fob is detected inside - why there is no external override to unlock the vehicle when the key is present - whether a software update or safety feature enhancement can address this risk this is not just a convenience issue—it is a safety hazard that can lead to dangerous outcomes, especially for children or individuals with disabilities. Please confirm receipt of this concern and advise whether this issue has been previously identified or is under review.

The electronics freeze up and sometimes the stereo turns off and won't come back on. The transmission perks and then revs up then hits gear and kicks real hard. The transmission feels like it's going to vibrate out from under the truck going down the road at certain speeds!.

The vehicle experienced a sudden loss of 4wd capability and transmission communication while driving. The dealership diagnosed a defective battery ground cable. Gm has issued customer satisfaction program n252515590 for this exact issue, but they are refusing to cover my specific VIN despite the truck exhibiting the exact failure described. This defect causes the vehicle to lose critical powertrain functions, posing a safety risk on the road.

Tailgate opens on its own after parking truck. No buttons inside or on the key fob are pressed and the tailgate randomly opens. Caused the battery to drain as well.

Oil cooler lines are leaking oil. A known gm issue with many owner complaints online. Transmission issues. Motor issues. Electrical issues. Brake issues. These particular trucks have many issues and nobody is taking responsibility for the issues.

Tailgate unexpectedly opened when driving. Switch on and off when parked and drained battery.

I’d like to report a serious, ongoing safety concern with my 2019 Chevrolet silverado (5. 3 v8 53,028 mi) since Dec 2025. Over the last 4 months, I have experienced at least 20 engine failures/loss of power, with no engine light illuminated after restarting truck. These failures result in a complete loss of power, including steering and braking, posing a significant risk of a crash. Chevy said it would be hard to diagnose with no engine warning light on. Feb 24th, engine failure, warning light stayed on and towed truck to chevy. Truck on standby, repaired Mar 10th, replacing 2 oxygen sensors per diagnostics. Picked it up on March 11th, but engine shutdown again the same day and 4 additional failures while driving in my neighborhood, making the truck undrivable. I reached out to chevy service supervisor, juliana, but have received no response for the last 10 days. I urge NHTSA to investigate this defect as it poses a severe safety risk. Thank you for your urgent attention.

The tailgate is clicking continuously and dropping at random moments when I’m stationary as well as driving. It is draining the battery and leaving me stranded with zero power or resources for help.

Truck will shut off then on rapidly when turning left. Alert messages on sensors come on and off as lights flicker on and off. Radio screen will go black randomly or not turn on. Ac shuts off and on randomly as well. Very dangerous while driving and you are about to turn left if truck shuts down. This happens at least once a week.

While driving with my trailer my tailgate opened by itself and hit my trailer when backing up. There is a open recall for a faulty switch that may allow the tailgate to open unexpectedly. I called my dealer and said they could only replace the faulty switch and not my damaged tailgate. It was due to the faulty switch that led to my tailgate getting damaged. I believe this switch and my tailgate need to replaced.

My vehicle frequently loses all cabin sound, including the radio, audible turn signal, and forward/rear collision and lane departure warnings. When this occurs, the cabin is completely silent. The loss of radio audio is an inconvenience, but the loss of safety feature alerts is a clear hazard. My dealership has suggested this may be related to a recent software update; however, there is no apparent correlation between the updates and when the issue occurs.

Component involved: visibility/backup device, electrical system, forward collision avoidance ?description of incident: the android 12-based infotainment system in this vehicle is suffering from a progressive hardware/software failure that creates a severe, multi-layered safety hazard. ?critical driver distraction: the system has become largely non-responsive, requiring me to repeatedly press on-screen buttons to perform basic functions. This forces me to divert my eyes and manual attention away from the road for periods far exceeding 2 seconds. This "visual-manual distraction" is a direct result of the system's inability to process commands, making safe operation impossible while attempting to use vehicle controls. ?visibility failure (fmvss 111): the failure impacts the digital rearview mirror and the safety camera feeds. These cameras frequently glitch, lag, or freeze, depriving me of necessary rear and surround visibility while moving. This is a violation of federal safety standards for rearview visibility. ?systemic electrical failure: this "slowly dying" system is also interfering with the vehicle's communication bus, causing the power door locks to malfunction. This creates an entrapment or security risk. ?I have reported these issues to general motors/onstar. Despite their awareness of these "electrical gremlins" and the existence of limited service updates (like program #n242435631), no permanent fix has been provided. This is a systemic safety defect that requires a mandatory recall to prevent accidents caused by driver distraction and visibility loss. The system needs updating to android 14. It is android 12 now. This is the fix. Gm want me to pay $250 for a hour for a macanic to update it. Gm was updating over the air, but it was causing the battery on the vehicle's to prematurely die under warranty. It was affecting their bottom line.

Battery keeps going dead 4 batteries in 4 months think it is caused by power tailgate release.

When entering traffic vehicle wheels locked up and engine stopped, when restarted vehicle was in limp or reduced power mode, check engine light is on, message on screen and in app identifies transmission and electrical problem. Anti slip was engaged automatically upon restart.
