| I recently noticed that my spare tire was missing. i took it back to the sear auto center that has been servicing it. when they looked under the car they said that it was common for the yukon spare tire cable to rust and snap off. so i lost the spare tire, spare wheel, and cable system to hold the spare under the vehicle. not sure where or when it happened, but it was in the last 2 years. just found out about this complaint service. have also had to replace the brakes and rotors a number of times (an excessive amount), and have had to have the a/c unit repaired twice. the first time i was told that it had the wrong control head. also, whenever i hit a bump i momentarily lose power steering. *tr | |||

| I purchased my 2001 yukon denali xl on november 22, 2006 and when i was driving it home from the dealership it died at a red light. it started right back up so i didn't think much about it. the very next day the vehicle died during acceleration when i was at about 20 mph. i had a hard time restarting the vehicle. it spit and sputtered. when i did get it started i tried to drive and when i used the brakes it wanted to die or it would idle up and make braking difficult. i could not maintain a constant speed and the engine kept dying. there is no way i could drive this vehicle without crashing it. at this point i decided the vehicle is unsafe to drive. i had it towed to the dealership. the next business day, they could not find anything wrong with it. its obvious there is a serious safety concern that is intermittent. it is now sitting at a different mechanics shop trying to find the problem. i have read so many complaints about these similar vehicles with similar problems. however, they have been broken down into different categories like yukon, yukon xl, yukon denali, yukon denali xl, or just denali. the complaints are also listed in different categories of complaint type. nobody knows what complaint type to list it under because they don't know exactly what is causing it. obviously there is an issue with unknown origin and resolution. and with the complaints being broken down into different vehicle and type categories, maybe it isn't realized these vehicles are all built on the same platform and have the same problem. this is a serious safety problem and something needs to be done. i can't even drive my new vehicle. *jb | |||
