“I have a 2003 Gmc sierra 4wd truck and the speedometer cluster is bad. I see that thousands of other people have the same problem. The speedometer register erratically and sometimes stays on 0 MPH while driving down the highway. I here the fuel gauge is next to go bad. These two problems together on a busy highway can and will cause accidents where someone will get hurt or killed. Gm has agreed to recall these vehicles with under 70,000 miles and 5 yrs. Old. This does nothing to this safety problem but lower the odds a little bit. …”
