My 2021 chevy 3500hd diesel had the engine light come on and the service emissions system popped up in the info screen. It said in so many miles speed would be limited. I took it to the dealer and they said the def tank would need replaced because the tank wiring connector overheated and would cost me over $2k.
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.
July 20, we were driving the 2021 3500hd to church w/our single axle trailer w/mower on it when we were stopped at a yield sign and proceeded to pull forward, our truck made a loud boom noise and immediately stopped. Warning lights on the dash began coming on, when the gas pedal was pressed it made a loud rpm sound of engine revving, following by barely coasting action. We were able to drift into the turn lane & get out of danger. We had to be towed to capital Chevrolet bc something isn't functioning properly. Dealership said they believe it's transmission related and the power train warranty should cover repairs needed. We have tow receipt and gas receipts for rental vehicle.
While towing my 5th wheel RV trailer, the rear wheels locked up numerous times while at highway speeds(60-70mph). Hope our didn't cause any internal/ structural damage to my trailer. Scheduled a service with the dealer(gamblins Chevrolet, enumclaw, wa) for them to diagnose. The dealer found no issue or cause. Left the dealer for the same thing to occur the following week. Brought back to the dealer for this issue and others to determine the torque converter had failed, dealer replaced converter, at a later date rear wheels locked up at highway speeds again. Been ongoing with no solution.
Bought the truck in 2021. Replaced both outside mirrors during warranty. At about 44000 miles the passenger mirror malfunctioned again. The mirror resets to downward position and when you restart vehicle you need to readjust mirror each time. This is very dangerous especially while pulling the 5th wheel. Received a warning lite for a safety restraint failure. Took the truck to the dealer and was told the passenger side air bag was defective and it was a $1700 repair! defective at 44000 miles? are air bags only supposed to last such a short time? this is a serious safety issue that should be addressed and covered by all manufacturers warranties!.
