What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
We tested the truck on a similar bank and found the brakes failed again under similar circumstances. We then tried five other chevys (2003 &2004 models) and found the same brake failure in all five every time traction was broken.
Speedometer baseline is now 100 mph. Goes up from there but not below. Turning off the vehicle does not reset it.
My vehicle is a 2004 allegro motorhome by tiffin built on a chevy workhorse chassis. The problem is with the instrument panel which has a small lcd display for odometer, oil pressure, and mpg readouts. The display has mostly failed and the information displayed is not readable.
The vehicle has an intermittent problem with the brakes failing to stop! We have taken said vehicle to, two different dealers, neither could find problem and continue to try different parts. The vehicle has a hydralic power booster on order to see if this rectify's the problem.
