2021 CHEVROLET SILVERADO 1500 Complaints

The contact owns a 2021 Chevrolet Silverado 1500. While driving approximately 30 MPH, the contact heard an object being dragged underneath the vehicle. There were no warning lights illuminated. The contact pulled over and heard an abnormal clicking sound coming from the vehicle before the vehicle stalled. The contact was unable to restart the vehicle, and the vehicle was towed to an independent mechanic. The mechanic diagnosed the vehicle and determined that the engine had seized and needed to be replaced. The vehicle was not repaired. The contact researched online and related the failure to NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the VIN was not included in the recall. The manufacturer was informed of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 100,000.

Good morning, While driving and starting my Chevy Silverado 1500 with 3.0 durmax it will suddenly go into a “limp mode” reducing speed and power. Recently while driving on a highway it reduced engine power causing the vehicle to slow down suddenly with many cars speeding by. This caused me to try and pull over the vehicle and avoid hitting other vehicles. When pulling codes off the vehicle there is a p1098 which refers to the engine coolant control valve. This will cause the vehicle to do the described power reduction. Upon researching the issue Gm has recognized and released a special coverage to fix the issue. N252508341. However my vehicles VIN does not pull up the coverage. All the characteristics of the coverage seem to fit the model and issues I have. It’s the same year, model, engine, etc. I’ve attached a DOT report of the special coverage. I’m hoping this will help fix my vehicle and others with this same issue. Although it’s not specifically listed as a safety recall, I feel the cause of the sudden power reduction is known by Gm and warranty issued and the problem should be resolved for all vehicles with this issue. Thank you!

Check engine turned on and at the same time the vehicle turned into safety mode abruptly, it slowed down to 10 miles an hour while on the high way and receiving a message stating that the "engine power reduced", the issue was presented to the dealership and they believe to be fixed with a sensor issue, the light came back on a few days after the initial repair and once again the engine lost power while driving the vehicle, the vehicle was then taken back to the dealership for repair once again, both times I mentioned the service bulletin, which they did not consider in their repair, stating that the issue was specific for a code (which all codes present are in the service bulletin) the 2nd repair was done on a actuator, which they stated should fix the issue, and did not, a 3rd time the vehicle lost power while hauling a trailer, this time I brought up the concern of them not reviewing the service bulletin, this time they confirmed that the service bulletin was the issue causing the check engine light (GM service bulletin no: 21-NA-149) now they are looking to slowly start repairing the issue and wait for the check engine light to turn on again to then go back and forth and review step by step the instructions in the bulletin.

2021 Chevrolet Silverado Z71 Sherrod truck with the 6.2 engine came apart (blew up) driving down the interstate at 65 mph. Had truck towed to dealership and was told needed a new motor. Truck has 89,000 miles on it. I was told truck does not meet recall because of the date it was manufactured but was acknowledged that what happened to it is what the recall is for.

As I was driving my 2021 Chevrolet z71 pick up I had a warning light appear on the dash indicating the safety traction control system was faulty, at the same time my truck had a loss of power as if it was not operating on all cylinders. I could hear some strange noises that were not normal, at the same time my transmission was shifting abnormally. I managed to drive to a dealer and was told it was a collapsed lifter on cylinder #5 this occurred out of no where, I was informed what took place could have damaged the camshaft and I could be looking at a repair cost upwards of $5,000.00 and the service writer indicated this has been an ongoing issue with the 5.3 liter engine. My truck has been serviced at the dealership it was purchased from, and all oil changes have been performed within a reasonable window from when oil changes and service inspection has been recommended by General Motors.

The vehicle has an electric tailgate lock switch failure/defect. The tailgate unlocks on its own and pops open while driving, at stop lights, in drive-thru restaurants, and while parked which causes a safety hazard to the driver and passengers in the vehicle, as well as other drivers around the vehicle. Even after closing the tailgate, it will unlock and pop open on its own again. Then, I tested the closed, locked tailgate by shacking and pulling it open from the top edge which caused the tailgate to unlock and open on its own. This causes a thief risk of personal belongings and vehicle parts. There are no warning lamps or messages about the component failure. Since no recalls for the vehicle's VIN number are listed, it has not been confirmed by the dealer.

On January 3, 2026, I started the truck, but it would not go into gear when I put into drive; I then attempted to put into reverse and same problem. I had to have it towed to the dealership, McCluskey Chevrolet, Kings Automall, Cincinnati Ohio, on Monday, January 5, 2026, this is where I purchased the vehicle on May 14, 2022, with 16,594 miles at time of purchase (estimated), it was towed on a flatbed, and arrived at McCluskey with 60,072 miles. Truck was looked and they found that it needed a valve body. At which time they told me GM warranty expired, over 60,000 miles, really by 72 miles. Ok there is a powertrain warranty then I had to prove oil changes, guess what I'm human and I missed two oil changes so the "extended warranty" McCluskey "gifted me" was void. I then complained I only drove the vehicle 43000 miles and for a 2021 with 60,072 miles this is an issue. Service advisor then went to management and they reduce the cost from est. 4000.00 to 585.00 plus tax through a program that GM offers. Picked up repaired vehicle on 1/30/2026, 2/1/2026 engine light came on went to have a veriscan and it found solenoid 3 stuck off & solenoid 4 (the one that was replaced) stuck on. This is an issue on gas 2021 Silverado 1500 and I wanted to report my experience because this is not "primarily" a diesel problem any longer.

6.2L L87 V8 engine experienced catastrophic engine failure do to lifter failure and a cylinder 8 misfire. Causing additional damage to camshaft. The dealership has inspected the vehicle and refuses to acknowledge the problem as there own. I have invoices for the work if I choose to proceed. Incident occurred while driving on the freeway, complete lose of power and control. This engine is known for this exact problem yet I never received a recall.

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

At 46000 miles the motor was replaced because of an internal oil consumption issue after the motor was replaced at 1500 miles the motor locked up while traveling down the road they rebuilt this motor. I went to go pick it up. Drove it 20 miles and oil was blowing out the rear main seal. after this, I sold the truck back to Gwatney Chevrolet and purchased a 2024 model with a 6.2 L I have not had any problems yet.
