Bought vehicle in February of 2009 used after driving truck for about 10 days we realized that the speedometer was not moving when the vehicle was in motion. Then after that the speedometer would move up in speed after driving the car for about 20 minutes but then stay at the 30mph when stopped once the car would begin moving again the speed would continue to go up from the 30mph mark resulting in the speedometer reading 60mph when the vehicle was actually only going 30mph. This has continued every day since it was noticed so when driving the car you never know how fast the car is actually traveling.
While driving vehicle lost power. Vehicle would not accelerate over 10 mph. Dealership was notified, but did not resolve the problem.
"reduced engine power" message displayed 3 times within 4100 miles of brand new Tahoe. On 4th visit, dealer replaced throttle body with a new one at 4366 miles.
