“My entire instrument panel does not always work when I start my truck. It will occasionally come to life after driving a bit or sometimes it doesn't work at all. No pattern as to when, where or driving conditions. Started a few months ago where it would always work shortly after I started the engine and has progressively gotten worse,”

“I can unlock truck with key or remote put key in start and dash lights come on but no start. After being told it was the fuel pump, the started, and key I know it has something to do with the anti-lock. I have reprogrammed it several time but each time a different way.

The malfunction has caused me to assume that I was driving slower than I was which has resulting in a high risk for accidents.”

“My '03 Chevrolet suburban has developed what appears to be a very common condition where the entire instrument cluster becomes inoperable. For example, while traveling at low, in town speeds, the speedometer will have readings in the 60s, 70s' and 80s. While in the park position, the speedometer will read 55mph. This is absolutely a safety issue and I am really shocked that the NHTSA hasn't forced a recall. There are literally thousands of reports online of this exact problem. General motors is aware that this is a wide spread problem, as they even extended. …”
