My 2002 Denali XL's transmission cooler failed mixing transmission fluid and coolant in the radiator. Result very quickly is slipping transmission. Car has 74000 miles, all normal family driving, never towed anything or did any off roading. The cost of the repair was over $3000; extended warranty paid $2000. I looked on the internet and quickly found this to be a common problem. Apparently the trans cooler is inside the radiator and therefore you can't detect the failure until you have a problem. One sign is coolant and trans fluid mixed in the overflow tank for the radiator, but by then your transmission will be ruined. I called GM to see if they would help cover the cost of my portion of the repair. They ultimately came back and said no since I take the car to an independent repair shop, even though they referred this issue to a GM dealer. I have been a loyal GM buyer, now am very disappointed. A part that is designed to extend the life of the transmission fails and causes early problems. Seems like they should own up to this. This is my last GM vehicle. If you are driving this car, watch out for this problem. |

I bought a brand new '05 Yukon Denali XL and haven't had any major problems. Lately, though, I've noticed when I park my vehicle outside for several hours or more that I hear a grinding or a metal on metal sound whenever I step on the brakes. It goes away after driving for a couple of minutes. I've taken it to the dealer and they've told me that it's condensation from the hot brakes and cold air that causes that noise. At first, I accepted that reasoning, but then why has it only started recently. If it were true, then I would have heard it since the beginning. My SUV is normally garaged so I don't hear any grinding whenever I pull out and step on the brakes. It's just whenever it's parked outside on a cold night. I'm afraid it could become worse. I've driven 36K miles on it mostly highway so the brake pads are still fairly thick. I think there's 5mm on the most worn out of pads and 8mm on the other axle. Anybody else have this problem?

Replying to: awf_axis (Jul 14, 2006 4:32 pm) A good example was about 2 weeks ago. I parked my SUV outside from 2PM until 11PM. I don't think there would have been enough time for rust to form or is that enough time for some sort of film to coat the rotors? |

| I have taken delivery of an 07 Denali with NAV and no camera (I couldn't wait). Does anyone know if the wiring harness is in the liftgate so that I can simply connect the camera when it becomes available?? | |

Does anyone know if 04 Denali is equipped with a fuel filter? I went to a GM dealer this morning and they called me back saying that 04 denali's are not equipped with a fuel filter. just curious if anyone came across this? |
