2004 gmc yukon xl denali system stabilization disabled warning light intermittently comes on. The dealer cannot repair this issue because there are no diagnostic codes in the car computer. I have taken the truck to the dealership with the warning light on, but still no error codes. After several trips to the service shop and it still is coming on. To date there have been no accidents nor injuries, I have lost confidence in the vehicle as I was told the stabilization system was mandated by the government and it must be operational. What recourse do I have to insure the truck is safe? Why can't they replace computer modules until there is a resolution? The truck did not do this for the first five years I owned it, driving the same exact roads that the warning flashes on now.

The ABS traction control on my 2004 yukon denali activates on dry roads and nearly caused a serious accident. While pulling out onto the road, the traction control kicked in and cut power to the truck. I couldn't accelerate and was almost hit by oncoming traffic.

Flashing ABS light and then alternating flashing tc (traction control) light. Then the vehicle locks up the left side front brake and pulls the vehicle into on coming traffic. Happens intermittently. Cause by the wheel speed sensor failing on the vehicle. Replacement of part removes issue.

2004 gmc yukon xl denali system stabilization disabled warning light intermittently comes on. The dealer cannot repair this issue because there are no diagnostic codes in the car computer. I have taken the truck to the dealership with the warning light on, but still no error codes. Onstar runs diagnostics and reports no errors and tells me to drive to the nearest dealership because the vehicle is unsafe. This first occurred in december while the truck was still under warranty, now several trips to the service shop and it still is coming on. I am working with gmc customer support to try to resolve the issue, but to date they are saying they can't fix it because there are no diagnostic codes. I have asked them if the truck is safe to drive with warning light on, but they cannot assure me that it is. They refuse to document anything in writing about the safety of the truck. To date there have been no accidents nor injuries, but I have lost all confidence in the vehicle as I was told the stabilization system was mandated by the government and it must be operational. What recourse do I have to insure the truck is safe? Why can't they replace computer modules until there is a resolution? The truck did not do this for the first 35 months I owned it, driving the same exact roads that the warning flashes on now.
