What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Full brake failure in 7/19 and again in 10/19. We were able to avoid hitting other vehicle as little traffic. Had them completely repaired both times. 1/20 brakes failed again causing us to avoid hitting other vehicles by jumping a curb and hitting a mile marker sign a parkway. That is 3 brakes failures in 7 months.
My GMC YukonXL Denali has faulty fuel gauges therefore there is no way I can determine if I'm are out of gas or not. Sometimes it displays that my tank is on empty and sometimes it display that I am full.
Driver seat not moving forward I've seen other complaints about this also the gas gauge isn't work nor is the speedometer we replaced stepping motors still not working this is a safety hazard knowing how fast I'm going..
I was driving and my car went into reduced power mode. Luckily, I was just a mile away from home and limped my car home. I've since cleaned the mass air flow sensor and throttle body. I've changed out the tps and acceleration sensor. I've checked all my grounds and these codes keep coming back.
While at a stop, the vehicle lost power and the traction control warning indicator illuminated. The vehicle accelerated eventually. The failure recurred several times. The vehicle was taken to an independent mechanic who performed an on-screen driving test, but was unable to find the failure codes.
Brake lines very rusted and leaking fluid both front to rear lines needed to be replaced. Had to also replace rear brake pads & rotors they were pitted and grooved. Needed to perform brake fluid flush , both rear axle seals leaking & rear cover gasket seal leaking on parking brake shoes all needed to be replaced.
While accelerating from a complete stop the vehicle goes into traction control or reduced engine power.stalling in the middle of intersections or at stop lights car behind expects you to move and you cant.
While accelerating from a complete stop the vehicle goes into traction control for no reason stalling in the middle of the intersection. The display flashes traction active even though the pavement is dry and free of loose debris.
