Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“There is a dangerous throttle lag when accelerating from a rolling stop. Many users have nearly had accidents like me. You press throttle and it does nothing for like 2 seconds then suddenly engine picks up... Its a gasoline v6 engine so its not turbo lag.... And when you are actually stopped and accelerate its just fine. Its just when slowly rolling its extremely dangerous!!!”

This was followed by a rain storm the day before. unlike previous issued I reported to the dealership where rain water leaked in other the console and passenger seat.”
NHTSA complaint #11748240, filed 2026-07“Car went black (all systems shut off) and i started to roll in the CVS parking lot when i was trying to drive in and Park. The brakes and nothing was engaging. IT happened so fast I was able to stop the vehicle and I am not sure how but may have just turned the shifter from drive to park... I took the vehicle in for service (a number of issues) and i forgot to mention this, I was told the Ground Stud needed replacing and it turned out this was likely the cause (I believe he said it had come loose). I have a extended warranty that has comprehensive coverage with CNA and they denied this part. …”
