2003 Chevrolet Tahoe Owner Comments

problem #2

May 152015


  • 220,000 miles


While driving on the interstate at 70 mph the car switched to reduced engine power and reduced speed immediately to 25 mph, leaving me in the position to navigate through rush hour traffic to get to the side of the road. After happening a couple of times over a 30 period, it is now a regular occurrence. Each attempt to take the car in to a mechanic to be repaired results in the same issue occurring afterwards. Mechanics seem not to be able to determine the cause resulting in a completely unsafe car. The throttle body has been replaced, wire harness, pedal sensor, and throttle body sensor. Nothing has solved the problem!

problem #1

Jan 032014

Tahoe 8-cyl

  • 110,000 miles
I was at a traffic light, waiting for it to change, and all of a sudden the brake went all the way down and all kinds of lights in the truck were flashing indicating trouble. I managed to pull to the curve, put it on park, and noticed that there was fuel coming down from underneath the truck. I called aaa, since I am a member, and they towed the truck to my local mechanic. The mechanic inspected the truck and noticed that both the brake lines and the fuel lines were corroded. I happened to read online about other Chevy owners that were having issues with brake and fuel line corrosion on the same model and year Chevy Tahoe I own.
