2003 GMC Yukon awd w/ stabilitrak. 40,000 mi. : when accelerating from a stop, the "traction active" dash display will very often come on, the powertrain disengages and I have to let up on gas until transmission re-engages. This has been occurring since September, numerous times a day. I have almost been rear-ended, since the drivers behind me presuppose I will continue accelerating. A gm dealer, after exam & diagnostics, could find no problem, even after being advised about possible "wheel corrosion. " in the meantime of course, it continues. An entry in edmunds "car space" has referred me to "document id#1819672 202 GMC truck GMC k sierra 4wd; subject: product safety - front wheel speed sensor corrosion #05068b - (04/21/2006). This seems to be a dangerous, serious problem which should merit a recall.

I have had my 2005 Yukon in the service department of the dealership that I purchased it from on several occasions. The service 4wd light and stability sys disabled lights keep coming on. They have replaced the first transfer case module and when the problem persisted they replaced the second transfer case module. I asked them to check the stability sys but they said they couldn't just check it without a recall. The lights continued to come on and more problems started occurring. The 4l and the service 4wd light and stability sys disabled lights would rotate flashing and I could not get the 2wd light to stay on and although it said it was in 4l it was still in 2wd and it tried to lock up a few times. Then the neutral red light was on and both warning lights were flashing but was still driving in 2wd. Next none of the 2wd, 4wd or neutral lights were on but both warnings were flashing and the (t/c) icon on the dash was displayed and I couldn't get that to go off but again was still driving in 2wd. Finally, it was literally locked into 4l, was making awful grinding noises, both warnings were flashing and (t/c) icon were all on and I couldn't get it out of 4l no matter what I tried. I was stranded (it was dark and late). I had to have it towed to the dealership. Now they have replaced the encoder motor but I am still very concerned there is still more damage and I am going to continue to have problems with it. If I had been going down the freeway or at a higher speed, I am confident that I could have been in an awful accident and been seriously injured or worse yet dead!I commute to work, have clients with me and always have children with me going to sporting events, field trip, etc. There has been ongoing problems with this vehicle since I purchased it in June 2005 and each time it gets more serious! I am very concerned for my safety and the safety of my passengers!!!could someone please call me regarding this serious issue-I am afraid to drive the vehicle now!!!thank you!.

We had our second brand new 2005 Yukon slt for about 1 week, with approximately 250 miles on it when the "stabilitrak" automatic stability control system caused the vehicle to lock up. We got this vehicle after our 1st Yukon locked up approximately 1 month earlier. We had just left our home and were on the street we live on driving approximately 15 mph, when we felt something weird, heard a grinding noise, and the vehicle locked up. The "service stability" light was on. The is exactly the same scenario that happened on our other 2005 Yukon. This time the dealership said they could not find any diagnostic codes present in the computer, or any route cause. We feel very uncertain of the "stabilitrak" system and feel that there should be a safety review. Had this happened at a speed of 60 mph or faster, we could be injured or dead. There must be other instances of this malfunction. Through research, we found that this vehicle was manufactured several months apart and at different manufacturing facility than the first Yukon. We would like someone to call us regarding this important issue, this is the second Yukon to have the exact same problem with the stabilitrak system.

We had our brand new 2005 Yukon slt for 1 week and it had approximately 226 miles on it, when the "stabilitrak" electronic stability control system caused the vehicle to lock up. I was driving approximately 45 mph on my normal route, a fairly straight route, when the vehicle made a loud grinding noise, became impossible to maneuver, and totally locked up. Had I been driving faster, I am confident that we could have rolled or been in an awful accident. The "service stability" light was on. The dealership was unable to pinpoint the cause of malfunction. General motors concluded that the yaw sensor had not been calibrated, causing it to enable the stabilitrak program without reason or warning. We did not feel comfortable with that explanation from general motors. The dealership agreed and got us another brand new Yukon. We would like someone to call us regarding this serious issue.

While driving at any speed vehicle had unsteady steering control, vehicle wandered back and forth across the road. Vehicle had been to the dealer on two separate occasions. Dealer informed the consumer that they could not find anything wrong.

Consumer states: when driving in a heavy wind storm the front end of the vehicle wanders to the left. When straightening it up it over composites. Gradually gets worse. Vehicle veers back and forth like it its going to go out of control.
