I have a 2008 GMC Yukon slt that I bought in Feb of 2015 with 94,000 miles. I have serviced it regularly from day 1 and even paid it off in 2.5 years. As soon as I paid it off, the very next month, my engine started making a weird noise once in a while w/ no check engine light so no one could tell what was wrong. At that same time my "service stabilitrak/service traction control" would ding about 40 times in a row. I serviced the 2 and it did not help for more than 2 days and it started again. This time the check engine light came on codes were for new plugs and fuel filter. Still didn't help. Then my engine blew! got that replaced and it still to this day is doing same thing! so, like the 330 others, we have a major safety issue that no one cares to address, and I'm done trying! if this man are having the same issue it's a GM issue! I'm copying the NHTSA and my atty general for help. Please click this link and read 330 complaints about the same exact thing and youtube has people actually stuck bc their car died. Mine did not ever die but it sure feels like it is and. It happens every single time I drive my Yukon! please help us! I'm on unemployment and cannot afford anymore repairs. I shouldn't have to pay for this many things to be fixed and still not touch the problem!

The car flashes reduced engine power, stabilitrack off and the car can barely go 30 mph. The engine runs very rough when it is doing this also. My code scanner displays code 641 which is open 5volt reference on bank 1. it does this more when the weather outside is warmer or the car has been sitting still while running. On more than one occasion it has happened while pulling out into traffic causing near misses and other times while driving down the highway. Just yesterday it did it 20 times in a four mile stretch. This car is no longer safe to drive.

I'm driving and all of the sudden the stability and traction controls lights start flashing, the check engine light comes on and it goes into 1st gear and won't shift out. It takes about 15 seconds to go from driving 60 miles and air down to 10. GMC had it a total of 7 weeks in the winter of 2015/2016 and couldn't find the problem. Doing it again now7/7/2016. Took it to another dealer. They think it's a wiring problem but can't find it either. Told me would just have to drive it till it gets worse. I noticed this last time it messed up that it had been shifting very hard that day. Very frustrating to pay that much for a vehicle you don't feel safe driving. Ready to trade but not sure I have much faith in GM vehicles after all the problems I've been reading about.

The contact suffered a concussion and the pregnant front passenger sustained back injuries and received medical attention. A police report was filed. The vehicle was towed to an independent mechanic where it was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 100,000.

While traveling on the interstate at speed (70) the stabilitrac light came on and reduced engine power message displayed. The RPM's went over 4K, then the Yukon slowed in traffic and I had to pull to the side before being run over. The accelerator was unresponsive at that time. I turned off the engine, waited about 5 minutes and then resumed driving using '3' to engage transmission instead of 'd' the check engine light remained on, but I made it to my destination 2 hours away.
