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.

The engine started to leak oil, coming down the passenger side of the motor. This was around at 22,000 miles. The dealer says that this is a leaking intake manifold gasket. It has taken them 3 separate repairs to fix this issue. I feel that my engine warranty from Cadillac should be extended, past the 5yr 60k powertrain warranty. We have had this vehicle now for 4 years, and we don't drive it alot. As of this writing 11/21/2023 the vehicle has around 29,000 miles on it. It appears that it is leaking again, so it will be going back into the dealer again.
