2016 GMC YUKON Complaints

The transmission quit working and we were almost in an accident. This is a known issue on the interweb and I think GM needs to step in and help!

Check engine light came on. Immediately went to reputable local repair shop. Shop advised push rod bent due to faulty engine. Advised to call GMC because not normal wear and tear. Called GMC expressed my frustration about this being preexisting issue w this engine. GMC corp told me I had to ship to GMC dealership at my own expense then they could help me. Local GMCs backed up 6-8 wks. Towed car 1.5 hrs away. Mechanic told me not to worry this happens all of the time, GMC will take care of it. Pointed out a row of new trucks with my incl new Escalade with same issue. I spoke to a sales rep about trading my car in for new but he said engine issue still not resolved. He advised me to lease Escalade for $900 because by the time my engine blew my lease would be up; if not GMC fix under warranty!! Mechanic said new engine but GMC will take care of it. I waited 3+ months for GMC to authorize repair. GMC said they did not get docs but mechanic sent me verification of conversation and repair order sent to GMC. Mechanic received an unrelated warranty from GMC that said my issue was not covered. Mechanic said docs sent made no sense bc he sent the right warranty and he was sorry and embarrassed by GMC behavior. I finally paid over 14K for new engine. Picked up my car and drive a block and car still knocking and engine light came back on. I had returned my rental and no way home. In tears dealership gave me my rental keys back still all at my expense. The mechanic calls me two days later to tell me my torque needs to be replaced. I am hysterical, 14k spent, and car still not fixed. GMC told me to pay additional funds for torque converter or pick up. Threatened to charge storage fees. When I discussed their liability GMC became very rude and antagonistic. They cut off my communication with their lead mechanic. Took care of back to local repair shop. He said this smells of a law suit so would not touch vehicle. I all communication 106 more files to share.

Engine light keeps appearing and when checked it shows catalytic converter needs replaces and its sensors need replaced. Brake light has short in it and I repaireable

In June 2024 I took my vehicle to the dealership for a ticking/clacking noise. The dealership determined lifter failure and that the engine needed to be replaced because the lifters/cam were not readily available from the manufacturer due to a known issue with L87 GM motors. Long block was replaced 7/17/24. I believe this should be part of the recall issued against L87 motors and should be extended beyond the 2021-2024 years initially noted.

The contact owns a 2016 GMC Yukon Denali. The contact stated that since owning the vehicle, the engine had failed on three separate occasions. The contact stated that prior to each failure, there was an abnormal rattling sound coming from the engine. The contact stated that the check engine warning light was illuminated on the instrument panel prior to the last two failures. The vehicle was taken to an independent mechanic after each failure, and the engine was replaced twice. Recently, the contact was informed that the catalytic converter needed to be replaced; however, the vehicle was not yet repaired. The manufacturer was notified of the failure, and the contact was informed that there were no recalls on the VIN for the engine. A complaint was filed with the manufacturer. The failure mileage was 74,000.

The contact owns a 2016 GMC Yukon. The contact stated that while driving at an undisclosed speed, the vehicle unexpectedly downshifted with the check engine warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed that the transmission had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 250,000.

Transmission failure, hard shifting, slipping and loss of power also severe shuddering. Very dangerous driving. I had to have the transmission replaced after taking the vehicle to a dealership and upon verification from same dealership reproducing the transmission failure. Massive financial loss, dealership stated these transmissions are known to fail. Manufacturer has been notified by numerous complaints. Compensation is warranted

6.2L collapsed lifter on cylnder 5. This os my second engine with the exact same problem as the first engine reason for replacement
