(1) none (2) pulled out on hwy at normal speed, loud wining, and loud pop. Transmission failed, left with only 2nd and 3rd gear. (3) called transmission shop and they described in detail the flaw that caused failure. They informed me that this was quite common in this model. I feel that this should be reported as a recall, to correct this defect.
While driving my 2002 Yukon xl, there is yellow light appeared on the I/p cluster message center. "service 4wd" and when gently apply/pressing on the brake pedal, the is some kind of loud mechanism noise in the front wheel driver side, and prevent the brake pedal from coming down. Three times that I almost rear end other vehicles. Took the vehicle to the dealership to get it fixed, the cost was $2212. 93 for fixing brake system failure including anti brake system and 4wheel drive. Dealer recommended to a report to NHTSA.
On 11/23/04 left for vacation noticed that fluid was leaking about two hours into our trip. Stopped at dealership in barstow, where we were told transfer case was heating up and expanding and that it had tiny cracks that the fluid was leaking out of. Needed a new transfer case ordered on 11/24 and authorized overnight shipping. Called from 11/29 to 12/3 when I was finaly told that part was on nationwide backorder and would not be shipped. My car was not ready until 12/15. I have concerns that this is a wide spread problem since the part was on backorder and that GMC will not reimburse parts and labor or rental car fees. I was also very disappointed in the customer service department. Contacted them and was told what info. To send. Sent it did not hear from for approximately three weeks then was told that they did not receive all info. Left at least 15 messages and never received phone call back called and asked to speak to supervisor and first was told no then finally found a representative that gave me supervisor. I resent paperwork that was supossedly missing and was told about a week and a half later that they would give me credit toward a new purchase or oil changes for the equivelant of 1 year.
