| Vehicle Speed Control problems |
Timing chain issues resulting in a loss of power of the vehicle while driving. The vehicle stalls out and shuts off. Or it will go into power saving mode and slow down to only 20mph. It did this to me one a major highway and I almost was in an accident. Way to many issues with GMC owners and the timing chain on their vehicles.
We have had 4 transmissions since we bought the vehicle. It slows down to almost a stop after it hits 30 mph and makes weird noises all throughout the vehicle. The back right tire sticks to the pavement and jerks when I start to drive. The key ignition has been fixed several times and still sometimes won't turn with the key or come out. Yes warranty told the repaid service company to fix whatever, and they did but it still after 2 more transmission hasn't fixed the issues. Engine light and not sure what else.
