In September, my vehicle would not start. I had it boosted and it started right up. The very same afternoon , it would not start and had it boosted. Drove it for 2 days without issue and on day 3 it would not start and boosting was unsuccessful. The vehicle could not be put in neutral and needed to be towed. The car spent several weeks at the dealer and I was told it was the battery which I replaced the key FOBS needed to be reprogrammed and then the wiring harness was chewed up. After several weeks at the show and over $1,000 later the car was returned. A month or so later , the car wouldnât start, could not get boosted and had to be towed back to the dealership. After 2.5 weeks , I was told it was corrosion on the wiring harness. Iâm concerned that these issues will persist and I could end up stalling in the middle of the highway, Vehicle only has 31,000 miles on it.

Both running light modules failed due to overheating because there was no heatsink thermal compound installed on either unit. They had to be replaced. Repair was successful.

The passenger side DRL/turn signal is dim causing the vehicle visability to be reduced and other drivers unable to see turn indications, increasing the risk of crash. The design of the unit places undue heat near the circuit board causing the unit to fail. The driver's side does not have this issue. This is a known issue with many post on forums on it.

VEHICLE SPEED CONTROL
1 Report4% of totalPreviewing the first 1 complaint summaries.
The throttle and accelerator pedal is very HOT- highly sensitive, resulting in jerky lunging upon start off in 1st gear from a dead or 1 mph stop. The vehicle has been into the dealer 2 times for this issue with the same repair comments, vehicle meets all factory specs and all XT 4 react this way- well that's not safe. If that's the case, then this is a design defect which is unsafe as the accelerator pedal reacts to quickly with a non-smooth action and lunging which could cause a rear end collision. Other car evaluators have also indicated the XT6 has a jerky accelerator, just like what I am reporting. It may be the TPS -Throttle Position sensor in combination with the APS-Accelerator Position sensor. Sometimes it is so violent it throws occupants backward into the seats. Dealer says within spec. GM needs to solve this issue.
