What owners say
The contact owns a 2020 Chevrolet Silverado 1500. The contact stated after an independent mechanic had performed an oil change on the vehicle, the vehicle was moved and parked. The contact stated that upon attempting to start the vehicle, the vehicle failed to start. The mechanic diagnosed that the engine had seized and there were metal shavings in the oil. The vehicle was towed to the dealer, where it was diagnosed that the engine needed to be replaced. The dealer informed the contact that the manufacturer had denied coverage because the vehicle was previously serviced by an independent mechanic. The vehicle was repaired at the contact's expense. The contact related the failure to the federal safety agency Action Number: PE25001 (Engine, Engine and Engine Cooling). Additionally, the contact stated while idling and while driving at various speeds, the vehicle made an abnormal whining sound. The vehicle was taken to Bomnin Chevrolet Dadeland (8455 S Dixie Hwy, Miami, FL 33143), where it was diagnosed that the transmission was failing and there were metal shavings found in the transmission. The dealer replaced the transmission. The vehicle was repaired. The manufacturer was not contacted. The failure mileage was approximately 25,000.
Truck was purchased new in 2020. The transmission has worked fine until recently. Since this summer there is a distinctive whine coming from the engine department. Very hard to isolate. The transmission this winter has been terrible. The cold functionality of the transmission now is even worse than when new. It hesitates to shift to second and to third gear when cold. The transmission now also exhibits a failure to up shift when the vehicle is moving. It will hang with elevated rpms 2300 to 3000 for a second or two before upshifting and lowering the rpms. The truck now also has random clunking when shifting into reverse from dead stop. The transmission does not shutter but there is definite loss of power and that can be contributed to a bad torque convertor. If it is not locking up correctly when in gear power will suffer to the convertor failing to engage the transmission correctly. The shifting issue have persisted and gotten worse. Dealer said he put a computer on it and said there were no codes. The dealer mechanic did not even try to road test the truck That is just ridiculous. I will be taking the truck in again
Whine sound possible torque converter does not go away. Surging or delay in switching into second gear upon first start up and put in drive.
2020 silverado 1500 duramax. Torque converter failed with 6700 miles on new leased vehicle. Originally began having transmission issues in nov 2020 with surging while stopped in cold weather. Dealer reseated all connections. Began to have loud whining when shifting. Took back to dealer and informed it is turbo whine. Not convinced. March 2021 began surging again. Returned to dealer and kept for week. Mechanic stated could not produce problem. As I drove to the main street at dealership began surging. Returned to service, mgr goes with me and confirms issues with whine and surge. Back in the shop. That was 22 march and as of 8 april; torque converter failure and ordered new bell housing. Going on 4 weeks without truck.
