CarComplaints.com Notes: It's roomy, but very poor gas mileage for its class.

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.

Periodicly, while driving in normal conditions, the radio will turn off, the instrument panel will blink, the door locks will repeatedly lock/unlock, transmission will feel like it is in neutral or the engine will completely turn off.

While a accelerating onto an interstate highway the vehicle began to shake violently around 50mph so I pulled over and turned off the vehicle. Read later online that this anomaly is called the Chevy shake. Called Chevrolet customer service and they told me to take my vehicle into my local dealership for diagnosis. I also learned Chevrolet are doing nothing about this problem.

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

May 092011

Tahoe

  • 40,030 miles
While driving approximately 70 mph. Vehicles engine and instrument panel cycled on and off randomly. Noting that once I was able to pull off the road and come to a complete stop the vehicle finally shutdown. Furthermore attempting to turn the truck on only resulted in flickering electronic equipment with no response from the engine. Two weeks following this event fortunately enough after the vehicle was parked we noticed that electric folding mirrors weren't responding to the push button actuating the folding mirrors feature. This event we were able to get on our camera phone. Same flickering of electronics and again the engine didn't respond, turn over. In both occasion it was only after sitting approximately 30min. That vehicle finally responded and turned on.
