CHEVROLET Complaints

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at approximately 40 MPH, the vehicle shuddered and downshifted independently. No warning lights illuminated. Additionally, an OBD2 diagnostic scan retrieved diagnostic trouble codes: U0146, U0101, and U0100. A local dealer was contacted; however, the vehicle was not diagnosed or repaired because the VIN was not included in any recall. Additionally, the contact related the failure to NHTSA Campaign Number: 24V797000 (Power Train). The manufacturer was not made aware of the failure. The failure mileage was approximately 84,000.

On my way to work the car overheated causing me to be stranded in the middle of no where without cell service. When it got to the dealership to repaire the car, they stated that it was a cylinder head. The dearship had my car a little over a month for repairs, the dealership did finally give me a loaner for the last week of the repairs but I lost work and a client due to not having transportation. A week after receiving the car back I still had problems with a check engine light coming on occasionally with loss of power and it would go away. I did not trust the car at all.

While driving 40-45 mph on a curvy mountain highway, the power steering suddenly stopped working. There was no warning message prior. Once the power steering ceased, a warning message displayed, "Service Stabilitrak". I was left in a situation which was challenging to steer the vehicle, and much more difficult to maneuver at slower speeds and turns. Soon after, I parked the vehicle and shut it off overnight. The next morning the vehicle started with the same warning message "Service Stabilitrak", but the power steering worked fine. I brought the vehicle into Chevrolet dealership service for inspection and diagnosis. Results are attached. The vehicle has not yet been repaired, and is available for inspection. Thank you.

When the vehicle is shifted into Park and the ignition button is pressed, the vehicle fails to shut down. The dashboard displays a "Shift to Park" warning message, indicating the vehicle does not recognize that the gear selector is physically in the Park position.To shut the engine off, the driver must repeatedly wiggle, slam, or cycle the gear shifter back and forth into Park until the electrical sensor finally registers the connection. This creates a severe safety hazard, as the vehicle can roll away if left unsecured, drains the car battery, and prevents the doors from locking properly.Crucially, this defect traps drivers inside an operational vehicle for extended periods while they repeatedly struggle to force it to shut down. This poses an immediate risk of heat-related illness or death (hyperthermia), especially in high-temperature environments, during heatwaves, or for vulnerable occupants like children and the elderly who cannot exit the vehicle safely until it is off.

Most of the time, the car will not unlock when the unlock button is pressed on the key fobs. Most of the time, when the key fob is on the console and the start button is depressed, the car will not start. It can take multiple minutes and attempts before the car will finally start. Changing the batteries in the key fob did not resolve this issue. When we took it to the dealership, they say that the Body Control Module is the cause of the issue. When we google that, we see that there is an existing GM-issued service bulletin for certain units of the same year, make and model of our car. We therefore would like it to be investigated to have this service bulletin expanded to include our vehicle. It is unacceptable for a three-year old car not to unlock, lock, or start reliably and isn't normal wear and tear and there have not been any accidents.

Front passenger tire was losing air, on the way to bring it to tire shop dashboard displayed tire pressure sensor, power steering system, TCM notification, Electronic brake control. Got it to the tire shop bought a new tire and they did a diagnostic test it showed TCM passed and failed, lost communication with power steering passed and failed, lost communication with inflatable restraint passed and failed. Once tire was replaced vehicle was jerking with TCM notification coming on and off like the vehicle was sliding.

I work from home, so I drive my car maybe once a week and only on flat highways. One day, I heard a loud booming crack and then suddenly the vehicle was making a grinding noise and pulling strangely. I drove directly to a mechanic and had them looked at the vehicle since it was highly concerning to me. They said that the rear differential had split suddenly and that it was actually extremely dangerous that I had been driving still. They said if it had fully cracked it might have ended in my death! Again, this car is very underworked and not driving over so crazy terrain or anything to cause damage. The mechanic also mentioned that they've seen this problem in this vehicle make a lot, stating, "it's very common". I had to drop 3 grand to fix this. Given the danger and that it's a common problem I'm surprised this isn't already a recall.

Brand new car just purchased the end of March 2026. Went through car wash multiple times with no issues until one day the shark fin antenna came off and broke the plastic anchors. Now the circuit board is exposed to weather hazards. I read online multiple times this is an ongoing issue with this specific make and model and still GM declines to cover this under warranty.
