Engine failure at 64,000 miles. Drove vehicle from home and then vehicle immediately began shaking violently. Truck driving fine up until that point. No warning signs. No check engine light beforehand. Vehicle now at GMC dealership and needs new engine for up to $10,000. GMC is not covering the expense. Gave $2,000 towards the repair. Vehicle past warranty period. Engine should last longer than 64,000 miles. Regularly maintained.
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.
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.
My 2008 Yukon xl is giving several error messages. Traction control off, service stabilitrac, check engine light remains on even after I've replaced the throttle position sensor, coil pack, full tune up nothing seems to fix the issue and I see that I'm not the only one experiencing this issue. Any insight on resolving this problem would be gladly appreciated it is also using more oil than usual.
Was waiting for a red light to change and suddenly my dashboard lit up saying it was reducing power to the engine, disabling stability control and something else. . I was not able to drive the car for for 2 hours after that. . . I. Got the car towed to my house and when I went back to fallowing morning the car started with out the engine light on. . 2 days after the same thing happened while driving on the highway at 65 mph, it was a scary experience since the car reduced power very fast to 20 mph. . Almost got into an accident.
