| Tl-the contact owns a 2005 gmc yukon denali xl. the contact stated the speedometer was inoperable and she was unable to determine how fast or slow she was traveling. the manufacturer was aware of the failure but did not offer any assistance since the vehicle had more than 85,000 miles. the dealer confirmed what the manufacturer had stated. the current mileage was 89,700 and the failure mileage was 85,600. no repairs were performed. bw | |||

| Purchased new yukon denali xl on 3/19/05. initially my husband and i noticed the seat position memory was faulty. problem was minor did not report it. replaced the head lights every 2 months ~ drove us crazy but we did not complain. less than 8 months paint on the console and accessory buttons peeled. finally on 3/2/07 i was driving to work and got a transmission hot message. furious and concerned i drove straight to the dealer for assistance. later that day i find out that my less than two year old truck costing about $50,000 needed a new radiator and coolant system, replaced radiator hoses upper and lower,heater hoses, replaced coolant jug, replaced thermostat, replace bypass hose and truck needed an extensive engine block cooling flush, further indicating that the transmission and radiator fluid mixed - totaling $2,100. truck was in the shop on 1/12/07 for regular scheduled maintenance, which included inspection of the radiator, coolant system and hoses. on 3/6/07, called to check on my truck to find out that there was slight damage to the transmission; however, the advisor stated i would not get the transmission replaced right now, just begin a service for a new vehicle just the words you want to hear after wasting your money on a luxury suv. i contacted gmc customer care and they indicated there are no recalls on the issue. after doing an in depth online search i am now aware that many people have had the same problem. gmc as well as the dealer act as if it's not a big deal so owners have not pressed the issue. many owners state that they are not interested in the run around so they get the car repaired and don't pursue the issue. this matter needs immediate attention and possible recalls. no automobile should have transmission / radiator/ coolant/ electrical (head light) /memory malfunction or cheap interior issues within 2 yrs. gmc needs to step up to the plate and except responsibility for their poorly manufactured yukon denali. *jb | |||
