The EPA estimates 14MPG around town, but you'd be lucky to break double digits if you like A/C or have any hills in your town.

2012 Chevrolet Tahoe Owner Comments

problem #2

Feb 282019


  • 20 miles


Cpm malfunctioned causing the throttle to become stuck in full open position. The vehicle was continued to accelerate and would not stop. Computer was stuck in 100% mode. Brakes including the emergency brake would not stop the vehicle. Tahoe continued to gain speed. RPM's running between 500-600 RPM. Traffic was everywhere turning onto a 2 lane side road and notifying 911 I put the car in neutral and turned the engine off. The vehicle coasted for another mile or more before stopping. The brakes were smoking at that point.

problem #1

  • 17,000 miles
I was passing on a two lane high way at an accelerated speed at which time the engine dies, no lights no nothing total engine failure. Luckily I have enough momentum that I safely get around the semi and continue to be able to coast until I find a safe place to pull over. I call my local dealer who will not come tow me as I am approximately 50 miles from home although I do have GM roadside assistance. I turn off the ignition and it does restart so I manage to drive to a nearby dealership and leave it there. Nothing shows up on the computer I refuse to take it home. Should they not be able to repair this problem I will hold the dealership and General Motors 100% responsible. Thank god my daughter and I are safe but this is a tragedy waiting to happen if not resolved.
