My '03 Chevrolet Suburban has developed what appears to be a very common condition where the entire instrument cluster becomes inoperable.

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. General motors even provided owners with a special coverage that extends the warranty on the instrument panel cluster for the condition described above, as long as the vehicles age and mileage falls within certain parameters. Those parameters are the main reason for my complaint. …
The anti theft system caused the engine to quit going down the hi way several times and was very dangerous some of the times and left us stranded sometimes. GM acts like they do not know what is wrong but there is ample info on the internet and even a fix but it disable the ats, it turns off the fuel to the injectors killing the engine. This happened many times. We had to be towed twice because it would not restart.
