“Multiple gauges on the instrument panel are malfunctioning. The tachometer is reading 5,000 RPM when the vehicle was in park, and 7,000 RPM when going 15 MPH. When I turn the car off the gauge sits at 2,000. The speedometer is clicking up (not a smooth transition to the correct speed). And it showing a lesser speed then I am going. When I turn the car off the speedometer shows it is going 10 miles per hour but will slowly drop down to zero. Both of these malfunctions could are a huge safety concern. …”

NHTSA complaint #10376787, filed 2011-01, 17,313 miles“I am filing a complaint .and will continue to file complaints until all of the consumers issues have been addressed. I understand that GM is not willing to hold theirselfs liable for these issues ,but people spend pretty pennies out of pocket to purchase vehicles from these manufacturers to spend more money to pay for repairs after just a short while of owning these . I have researched issues I am having with my vehicle , and I am having all the above listed issues , and do not wish to spend large amounts of money to pay for these cost considering I am still paying for this vehicle . …”
NHTSA complaint #10382537, filed 2011-02, 80,000 miles“I own a 2003 chevy Trailblazer. It has just over 60,000 miles. The speedometer stopped working correctly a few days ago. The speedometer reads between 85-120 MPH no matter how fast I am driving. I have been told by my local chevy dealer that it will cost around $400.00 to have the speedometer repaired. I believe Chevrolet should be responsible for the replacement/repair costs since this is a safety issue that numerous other chevy truck/SUV owners have also experienced. They should have recalled the speedometers on their suvs/trucks a long time ago.”
NHTSA complaint #10175523, filed 2006-12, 60,650 miles“The problem happens when coming to a stop the engine will surge or jump as much as 2000 RPM's and you really have to be on the brake to hold it. Go to neutral let it rev then it will come back to normal. The last time was on a snow packed intersection with two other vehicles in opposite directions. The bad thing is you don't know when it's going to do it. Had it to several garages and nobody can duplicate it and it shows no codes.”
