Noticed when pressing tailgate release button manually it would not open but would if fob used. However tailgate opens continuously on its own.

- Minocqua, WI, USA

The tailgate randomly opens and closes during driving causing contents to fall out of the tailgate and creating a hazard for other motorists and damaging personal property. The tailgate now will not open and there is no manual override to open the tailgate. Certainly a design flaw and now not allowing access to the tailgate. I've contacted 5 local gm/chevrolet dealer service departments and they cannot offer any guidance on how to manually or power open the tailgate. I have a tonneau cover on the tailgate which makes it pretty much unable to access. I'm a firefighter and put my gear in the tailgate and need access asap. Please advise on how I can get GM/Chevy to assist with this issue. A police officer was behind me when the contents fell out of the tailgate on 6/9/25. This has happened several times since and most recently on 1/17/26. This needs addressed asap. Thanks!

Vehicle: 2021 Chevrolet Silverado Issue: Infotainment system failure after GM-?'pushed OTA update Description of Problem: On 10/31/2025, my vehicle-??s infotainment system attempted an over-?'the-?'air software update. The update failed and the screen has been locked ever since, displaying only the message: -??Update Failed -?" Return to Dealer.-?? As a result: - I cannot access any settings (clock, preferences, system menus). - All warning chimes and signal sounds (turn signal click, seatbelt reminder, back seat reminder, etc.) are disabled. - The backup camera still functions, but no other infotainment features are usable. - The system is completely unresponsive to reset attempts. I brought the vehicle to a Chevrolet dealer, who verified that it was the OTA update that caused the failure, they attempted a reflash but was unsuccessful. They now claim the entire infotainment unit must be replaced at my expense, even though the failure was caused by GM-??s own update which I neither approved, initiated, or requested. My vehicle is out of warranty, but this was not a wear-?'and-?'tear issue -?" it was introduced by GM-??s software. Safety Concern: The loss of audible warnings and chimes poses a safety risk. Drivers rely on these alerts for seatbelt reminders, turn signal confirmation, and other critical notifications. A manufacturer-?'pushed update disabled these among other functions including radio, navigation, and all vehicle settings. Resolution Attempts: - Dealer attempted reprogramming on 11/6 (charged $295) but failed and state I need a new infotainment system. - GM Customer Assistance refused to provide goodwill coverage. - Vehicle remains stuck in failed update state as pictured. Request: I am submitting this complaint because GM-??s OTA update disabled core safety features of my vehicle along with other basic features such as radio. I believe this is a manufacturer defect that should be investigated and addressed, regardless of warranty status.

The air conditioning only blows HOT air. The vehicle was inspected by my mechanic and states that the compressor and belt have failed and needs to be replaced. I realize that my 2020 Silverado is out of warranty, but after looking into this situation, I have found that GM has had known air conditioning issues with certain Silverado models, especially 2019-2021. I believe this is a widespread defect and should be covered and repaired through a goodwill program. I am bringing the Silverado for repairs to my mechanic on 10/31/25 as I live in South Florida and cannot continue driving this vehicle without air conditioning.

The following is a list of persistent electrical failures in my vehicle, several of which present a significant safety risk. I have attempted to resolve the issues: -??Emergency OnStar Button Failure: My vehicle's emergency OnStar buttons consistently fail to function when the ignition is off. This is a critical safety defect, as the system is designed to work on a backup battery during an emergency, such as a crash. The system only operates when the ignition is on. -?? Excessive and Dangerous Floor Hump Heat: Following a service visit on October 2, 2025, the front floor hump became excessively hot, melting personal items and posing a fire and burn risk. -??Fabricated Safety Warnings: The vehicle's computer system repeatedly displays false and misleading messages. Examples include an incorrect "new brake pads detected" prompt and a "taking your eyes off the road" warning that does not apply to this vehicle. These phantom messages are distracting and can cause driver confusion. -??Persistent Connectivity Failures: The vehicle experiences frequent and consistent failures with its Wi-Fi and GPS systems, indicating a potential electrical or software malfunction. Numerous resets attempted by the manufacturer's technical support have not resolved the issue. -?? Computer Display Anomaly: the Chevrolet symbol appeared in red on the computer screen when the truck was started. The vehicle has repeatedly experienced spontaneous changes to the radio station and the air conditioning switching from cold to hot without driver input. -??Unusual Decompressing Sound: When the vehicle has been sitting for an extended period, an unusual decompressing sound can be heard coming from the rear underside whenever a door is opened. Date: Software updates on January 27, 2025 and October 2, 2025. Diagnostic Test performed on October 2, 2025 that failed to resolve the issues. The OnStar buttons only works when the vehicle is turned on. I do have photos and videos available to support your claim.

I am filing a formal complaint regarding a serious safety concern with my 2021 CHEVROLET SILVERADO, following the completion of recall N252494001 performed by Galleria Chevrolet in Dallas, TX. Prior to this recall work and related inspections, my vehicle operated without any abnormal engine noise. After the recall inspection and a subsequent fuel injector repair performed by the dealer, my vehicle began producing a bottom-end engine noise that had never been present before, and ultimately we have catastrophic engine failure. What is highly concerning is that the dealership staff previously documented the situation in writing as follows: -??We performed the recall inspection and the truck passed. After performing an injector repair now there is a bottom-end noise when it's running. Did the failed injector possibly affect the validity of the test" That may be the case. We know that the truck did not experience the noise before the inspection; is it possible that the steps we took affected the truck in a way that got the noise to show itself" That-??s what we need to determine.-?? Despite this acknowledgment, the dealership is now denying any responsibility, classifying the damage as unrelated -??wear and tear-??. This reversal appears highly suspicious, as it contradicts their own observations and written notes. It suggests that the dealership and GM may be refusing to fulfill their obligations under the recall and repair warranty, leaving me with a vehicle that has a blown engine and a significant safety risk. Given the timing of the noise, occurring directly after recall work and injector repair, and the internal documentation from the dealership itself, I request NHTSA investigate whether: This issue is part of a broader trend affecting other vehicles under the same recall. GM and its dealers are properly honoring their obligations to fully repair vehicles impacted by recalls. Consequential damage resulting from recall work is being systematically denied coverage.

I purchased this truck 3/20/2025. I have since realized it wasn't me doing something wrong. The truck hesitates and shakes during shifting upon acceleration from a stop and when putting it in park and attempting to turn the truck off it has a message on the display saying "shift to park" and it will not turn off until you repeatedly restart it and play woth the gear shift to get it to register that it's in park. I have made an appointment to take it to the dealership to be looked at. The truck has 75,000 miles on it.

Around May 20th, 2022, I was driving the pickup when it suddenly the engine turned off on me. I was travelling at approximately 40 mph on city streets and was able to control the vehicle and park the vehicle and restart it. That same week, I took the vehicle to Chevrolet on the city of Orange, where it was inspected. According to the mechanic, no issues were located. Nothing else was done to the vehicle and as a result, I fear the same issue will happen again in the future.

Transmission isssues hard shifting and no shifting at times. I informed the dealership about the recall on this issue and they are saying it doesn-??t fall under the recall which isn-??t true because my vehicles is showing all of the symptoms under the recall #N242454440.

When I am driving my vehicle and I pull in to park, I put the gear shift into park and shut the vehichle off and a light comes on in the dash and says shift to park. And the vehichle will not shut down for several minutes after this light comes on. It also feels like there is a hesitation in the transmission at times after I start the vehicle and start driving.

Diesel engine continues to overheat, even after the oil temperature sensor failure dealership repair. Truck is very well maintained. However, common and trending issue amongst 1500 Silverado diesel owners is overheating which causes engine to loose power while driving and even get so hot it can catch fire. Warning lights appear only when problem is at engine failure point. Also, we lost power or reduced power on freeway which almost caused an accident and engine was smoking. We had it towed to Epic Chevrolet in Sacramento, CA. Within one week of dealership repair covered under powertrain warranty, dealership said overheating engine is due to a -??new-?? code for coolant pump. In short, fire and driving safety hazard that can cost lives if not addressed by NHTSA.

I had my windshield replaced and the installer said when he removed the old glass, the bottom of the glass didn't have the rubber strip accross the bottom. Our rear sliding window has had a small leak, so we asked him to check it out too. He noticed that the window also does not have the rubber weather seal.
