2017 Chevrolet Tahoe

The contact owns a 2017 Chevrolet Tahoe. The contact stated that the check engine warning light was illuminated on the instrument panel. The contact stated that the vehicle hesitated while depressing the accelerator pedal after cold starting the vehicle. After a diagnostic test by an independent mechanic, DTC: P0300, P0420, and P0500 were retrieved, indicating an engine misfire. The mechanic informed the contact that the fuel injectors needed to be replaced. The manufacturer was notified of the failure and confirmed that there were no open recalls associated with the VIN. The failure mileage was approximately 130,000.

My check engine light and traction control light came on at approximately 157,000 miles. I was not safe. I was in the middle of the freeway. My Tahoe slowed and sputtered! I had to be towed. I got an inspection at Folsom Buick GMC in Folsom, CA at the recommendation of GMC General Motors Corporation. Fuel Injector #6 failed and required replacement. The dealership would not repair the fuel injector under the Special Coverage N182198000, stating your 7,000 miles over the special coverage. They wouldn't even provide a discount for the quoted $1832.00 dollar repair. Though General Motors Corporation sent me to their 3rd party partner for the inspection, they also refused to offer any help with my bill, further stating you're over the mileage. General Motors Corporation also sent out bulletin 11-00-89-005W, where it specifically states dealers are required to use the Policy Evaluation Tool and are encouraged to follow the recommended amount of GM participation towards the repair cost, and they failed to honor their own bulletin and product.

My chevy tahoe vibrates when i drive and the dealership can not find the reason why it does that.

The Active fuel management system caused the engine to fail

They radio screen and radio navigation system. It will run batteries down replaced 2 Batteries this year. Radio goes haywire changes channels, makes dinging sound, navigation goes off. Screen moves jumps changes volume. Hard to drive very distracting and navigation stops working. None of this will stop until the vehicle is turned off and generally on restart it starts back up. Makes for very unsafe driving distraction. It started about a year ago it would happen occasionally now it’s every time you start the vehicle and drive. The constant noise and movement is again unsafe distracting and disrupts driving and anyone trying to have a conversation in my vehicle. Very very unsafe…

The contact owns a 2017 Chevrolet Tahoe. The contact stated that while driving on several occasions at various speeds, the check engine warning light illuminated, and the engine started running rough. The vehicle was taken to a dealer where it was diagnosed with three inoperable fuel injectors. The contact was informed that the fuel injectors needed to be replaced. The vehicle was repaired, but the failure reoccurred approximately four years later. The contact stated that while driving on several occasions at various speeds, the engine was running rough with the check engine warning light illuminated. The vehicle was taken to the same dealer where it was diagnosed, and it was determined that fuel injector #5 needed to be replaced. The vehicle was repaired, but the failure reoccurred approximately 2 and a half years later. The vehicle was then taken to an independent mechanic, where DTC: P04320 was retrieved, and the fuel injector on bank one that was previously replaced was not running at the right efficiency, and the catalyst for bank one was not operating as needed. The vehicle was not repaired. The vehicle was taken to the same dealer where it was diagnosed, and it was determined that the fuel injector that was previously needed to be replaced was at 20% and did not need to be replaced. The vehicle was not repaired, but the failure reoccurred approximately 7 months later. The vehicle was taken to the same dealer, where it was diagnosed, and it was determined that all four injectors on bank one were inoperable and needed to be replaced.

My 2017 Chevrolet Tahoe equipped with a 6L80 transmission began experiencing transmission-related drivability issues at approximately 130,000 miles. The vehicle jerked on takeoff, had delayed/slow shifting, produced a whining noise, and later had intermittent shuddering/surging while driving. During service, metallic debris/shavings were found in the transmission fluid. The transmission ultimately required replacement at my expense. I am aware of GM Technical Service Bulletin 20-NA-142, “Shudder/Surging While Driving,” which includes 2015–2022 Chevrolet Tahoe models equipped with MYC/MYD transmissions and discusses conditions that may be identified as torque converter shudder. My vehicle’s 6L80 transmission corresponds with GM RPO MYC, and the symptoms/repair findings appeared consistent with the bulletin. I am filing this complaint to document the transmission failure and related safety concern, as the jerking, delayed shifting, and shuddering affected normal vehicle operation.
