NHTSA Complaint #11711888 — 2021 GMC YUKON XL

While driving my Yukon it felt like there was an issue while it was trying to shift gears. the vehicle would sort of jerk while it was shifting. there also began to have a knocking sound as I drove. I had my children in the car, making this a more stressful situation. Having issues while driving on a highway with other vehicles driving at high speeds. Your vehicle having issues accelerating onto said highway as well. This all happened with only 68,445 miles on the vehicle. I called to schedule an appointment, drove it into the GM dealership. They stated that the lifters needed to be replaced and it would not be covered. As well as a rental vehicle not being covered, so both items came out of pocket. As I drove home from the dealership after they assured me everything was great, the engine light came on. Brought it back into the dealership to fixed again! This time it was the catalyst converter. This issue was covered by warranty somehow even though they stated it was tied together.
