Transmission went out very early. Had to get it replaced whenever I reverse. I have to really smash on the break in order for it to stop if it does stop so somethings wrong with the breaking whenever I hit a bump the left side suspension feels like I’m a lose control and sometimes my radio works and sometimes it doesn’t I’ve been trying to work with dealers I have extended warranty on it. They’re saying it’s not covered something about the brake pump is covered, but the belts are not. The transmission was put in only because it left me stranded. Otherwise I would’ve been stuck paying for that. The dealership actually helped me with that. My GPS turns on and off sometime. I’m not sure if it’s electrical

THE fuel pressure line from the fuel pump to the flex fuel sensor chaffed a pin hole leak near the front top of the fuel tank. This caused a significant fuel smell and trace leak at the front of the fuel tank which could lead to a fire or explosion. The new hose has a longer chaffing covering leading me to believe gm knew about this issue. vehicle has 127,000 miles. I feel gm should reimburse me for this repair as a fuel line should not have ever chaffed through and leaked.

The LED left turn signal and blind spot detection ( safety feature) on the left outside rear view mirror suddenly stopped working. The is a TSB for warranty for 2016-2018 GM YUKON (#10-08-64-002D) and it states that the bulletin has been revised to include 2016-2018 year models for this defect. I am starting this claim because I am told by GM that my VIN is not covered under this warranty, yet I am experiencing the same issue stated in the TSB listed above.

A side detection module pin was corroded and was disrupting the electrical signals to major vehicle components, such as the dash (DIC). The DIC would lose communication with the rest of the vehicle while driving so no vehicle operation data was visible such as speed, alerts messages, etc. This likely also caused engine failure due to the incorrect operation of the afm which is on the same electrical circuit. No warning messages were given. The bad side detection module was diagnosed and fixed at a dealer and shortly after engine issues were noticed.

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.
