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. I found online that over time, the contacts in the fuel-level sensor could wear and cause an incorrect reading on the gas gauge. In 2011 GM said that they would pay to repair.

What 2006 GMC Yukon XL owners say
Most recent owner complaints, unedited.
My stability traction control system engages in dry weather when accelerating from a stop, additionally, the system engages at moderate speeds which causes the vehicle to slow speeds in traffic. Also, the anti lock brakes engage in dry weather at slow speeds when braking. These situations have occurred on several occasions for the last several months
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..
Codes p1516, p2135, and p0120 have returned for a third time. 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. I've noticed other people having this same issues which is why I did the steps listed above. I've taken it to a mechanic who said that I did every step they've would have done to troubleshoot this problem. Someone from gm needs to this issue, as I am not the only one that this is occurring to.
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. Vehicle is now totaled. This seems to be a huge issue! No injuries, thank god!
Tl* the contact owns a 2006 gmc yukon xl. 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. The dealer was contacted (john paul's gmc, greenfield, wi, 414‑482‑6246) and the technician stated that the failure could not duplicated because the dealer used the same diagnostic system as the independent mechanic. The vehicle was not taken to the dealer. The manufacturer was not made aware of the failure. The failure was not repaired. The failure mileage was approximately 180,000.
From the stopped position gas pedal goes dead at accelleration. This is super dangerous when moving onto a traffic situation. The vechicle stall and a gringding sound appears. This happen I ntermitently. Gmc recalled outh gmc yukons to correct this deffect but not mine. Please help
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. I heard there was a problem with older modle SUV's and had mine looked at and was advised not to drive until these repairs were completed. I have all repair invoices to vehicle.
While driving my SUV on the freeway, the ABS ,traction controll,brake lite on the instrument cluster started flashing and chiming. Service stability was flashing on the dic. The dealer said the ABS module needs to be replaced. There is a loss of HVAC controll ,no AC and ventillation or heating,loss of cruise control. Please advice.
Electronic stability control activates randomly. 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. You have to either turn car off and back on or put in netural to try and get your car to go this is a very dangerous problem that leaves you feeling helpless and no control of your vechical I pray that this is looked into before someone gets hurt I also reported this to gmc
