NHTSA Complaint #11543357 — 2021 CHEVROLET TAHOE

Wife was driving home from work, vehicle started with no issues and she did not notice anything abnormal as she started her commute home, roughly 20 minute commute. She noticed the vehicle was vibrating, mildly at first and progressively getting worse. When she came to a stop at red light, she noticed the vibrating was worse at idle. She did not note any warning or cautions, she contacted me, i advised her to attempt to make it home. Once the light turned green, she accelerated and noticed the vehicle smoking, she pulled over into a parking lot, parked and shut it off. By this time all the warning in vehicle were flashing, battery and oil pressure gauges were fluctuating, check engine light was flashing, traction control, and other adaptive sensors i.e. blind spot, HUD where signals were displayed as off or not functioning. I was able to drive the vehicle to .4 miles to the dealership service center where we purchased the vehicle from in 2021 brand new off the lot. This occurred on 6 September 2023, still awaiting final diagnostic from from service department. They think its the lifter on the engine that failed, but they have disassemble engine to make exact determination. Once I receive diagnostic/invoice details I can provide that, luckily vehicle is still under warranty.
