ELECTRICAL SYSTEM, ENGINE, STEERING
I am filing a formal safety complaint regarding a persistent and unacceptable failure with my 2021 Chevrolet Silverado Trail Boss. The vehicle intermittently fails to start due to a recurring “Service Steering Column Lock” error. While the key fob still locks, unlocks, and remote starts the truck, the push-to-start system becomes entirely non-functional once inside the vehicle. This defect is not only frustrating — it’s dangerous. My wife has already been stranded twice, once in below-freezing temperatures in January, and again in May, causing her to be late for work and left alone at night in unsafe conditions. A truck purchased for over $60,000, marketed as rugged and dependable, should not be experiencing a critical failure like this at just 48,000 miles. What’s more concerning is that this appears to be a known issue within the GM community, with no official recall despite Technical Service Bulletins (TSBs) acknowledging the problem. Customers are being left with unreliable transportation and no consistent fix. This failure is both a mechanical and safety issue, leaving drivers vulnerable without warning. I urge NHTSA to investigate this defect, pressure GM for a formal recall, and ensure corrective action is taken before someone is injured due to being stranded or the failure progressing to more critical steering or ignition malfunctions.

STRUCTURE:BODY
The tailgate opens by randomly. I was in a CVS parking lot walking towards my car and saw the tailgate open without any commands. A young kid running towards his mother's car was just able to avoid running into it and getting 'clotheslined'. Another vehicle found it necessary to drive around the tailgate protruding from the parking spot. I have been finding the tailgate down multiple times, and thought I may have left it open even when I was sure I didn't. I also shut my tailgate recently and noticed I have a large dent in the tailgate itself when I closed it. It may have opened on another vehicle, or it was open when I was backing up assuming it was closed. After reading online I came across many owners having the exact same problems with the exact same truck. GM has told me the problem is VIN specific, and my VIN was not listed; therefore, no recall notice ever sent out to me.

Driving to work my engine failure light came on….the engine immediately sputtered. I immediately drove inside the bay at Ozark Chevrolet. As soon as I pulled in….the technician told me to turn it off and that I wouldn’t be driving it anymore. See my statement for $3,429.15. I have to carry my grandkids in this vehicle. I traded it in on Tundra. And now I find out about the recall. It was the 8cyl engine currently under recall.

Driving the truck at 45 mph, the engine stalled and the dash had all the lights on showing codes. Had it towed home and called the dealership the next business day. I was told it was the drive belt pulley that had gone bad causing loss of engine power. I had that replaced and the dealership then told me that the lifters were bad. I had to get that replaced because I needed my truck. The dealership had had it for almost three weeks at that point. $1300 to replace a lifter.

The full cost breakdown is: Labor & Parts Subtotal: $11,402.78 Shop Fees & Tax: $467.13 Total Estimate: $11,869.91 Yes, the vehicle is available for inspection. it has been inspected by a chevrolet dealership and they gave us the above estimate to repair it. The vehicle powered down while driving on the freeway. It has not been inspected by police or insurance representatives, only by the chevrolet dealership service department. No, there were no warning signs prior to it powering down on the freeway. When it stopped producing power needed, the engine light came on as well as emergency brake light. This issue started on the freeway on Tuesday, April 29, 2025. The vehicle is only 4 years with only 130,000 miles and one that has been properly maintained. We believe this failure is not due to neglect or wear, but rather a known manufacturing defect.

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.

The engine rods went bad in the engine and damaged the cam shaft. The vehicle only has 71000 miles on it. The resulting repairs cost approximately $8000. We have been told by the Chevy dealer doing the repairs and also the dealer we bought the truck from that this is a known problem and they have had several vehicles with the 5.3L engine that have needed this same repair.

Our tailgate would open on its own intermittingly. We haul our fifth wheel camper and this could cause damage to the RV and our vehicle. There have been recalls on one year older trucks and one year newer but not for the 2021Chevrolet Silverado. A Chevrolet dearlership in Florida looked at it for us. They said cause : checked for codes and bulletins. Found code B153D. Completed circuit check. Also found tailgate hatch out of adjustment. Corrctionj: Rec. replace switch and adjust latch. We were charged $486.05 for this. We feel this should be a recall problem. Please advise.
