Tahoe Hybrid Stock 6 Litre

  • Automatic transmission
  • 88,000 miles

The truck randomly (although only on second starts of the day, after driving to work and sitting for hours) coughs and bucks, then the throttle does not respond to the accelerator pedal. After some variable period of time the truck will usually accelerate violently (responding to the pedal inputs that you already tried). I have had to put both feet on the brake to prevent an accident.

Throws no codes. Two dealers over multiple visits over multiple years cannot diagnose this. Throws no codes....

Also when tranny is cold it slips while driving.

Also in the hybrid function range of 20-30 mph the truck transmission seems unable to figure out what mode or gear it wants. The transmission has already been serviced once. Still does it.

Also transitions from hybrid to IC have become rougher over time.

Also, one month after the rust through warranty expired I have rust through. Sorry, not covered they said.
