Speedometer does not read accurate. It either reads 15 mph at highway speeds, or goes way high such as 120 mph at 55 to 60 mph. Sometimes at the higher reading, it will read 60 mph when vehicle is stopped, in park, and ignition off. I was told this is a stepping motor but hard to change and expensive to change. I have read that there was a class action lawsuit that was never brought up.

Speedometer malfunctioned.

We have a 2003 Chevrolet Silverado and a 2004 impala. Speedometers have broken on both. The impala was replaced under warranty. The Silverado was turned in under warranty but not repaired and now it is out of warranty. This apparently is a major and widespread problem with Chevrolet vehicles and the company will not stand behind the product. Bob howard Chevrolet in oklahoma city tells me cost to fix this problem is $400-600 for the part and $125-175 for labor. How many of these module clusters have prematurely malfunctioned? mechanics and gm service centers say they are on national back order. That should illustrate the need for review and recall.

My 2005 chevy Silverado 1500, 4. 3 engine and 4 speed auto transmissionhas a problem when using cruise.

The consumer complained about an instant acceleration problem when approaching a stop sign or red light and when applying brake pressure. This often occurred when stopping at low speeds, such as 10 mph or lower, and was intermittent in nature. This has happened at least five times. When brakes pressure was applied the engine suddenly revved. The consumer applied brake pressure and rear wheels spun, smoke appeared, and burning rubber fell on the pavement. The vehicle has been taken to the dealer several times for this problem. The dealer checked the calibration and performed a diagnostic check. These measures did not reveal any type of problem or failure. The dealer installed a device into the vehicle to record any incident. However, while the device was installed there were no recorded incidents of this type. A call was made to the manufacturer, who sent a factory representative to inspect the vehicle, no failure was determined. No corrections or repairs were done at this time. The consumer felt this was still a problem, most recent incident occurred yesterday with no explanation as to why this happened.

My speedometer and tachometer quit working along with a tail light my mechanic said the part alone would cost 300. 00. I thought my tach was still working until I got a 150. 00 ticket. I can't afford that much especially with my ticket.

Speedometer reads erratically well above or below actual speed or may read correctly then become off be a little or a lot without warning. Dealer says they have had a rash of these failures. Could result in unsafe speeds without notice. I first noticed it in a 35 mph zone when the speedometer read 35 and I was passing everyone quickly.

Speedometer reads erratically either highor low. Will register various speed when stopped. Sometimes will work properly, then go bad again. 1st noticed when read 35 mph on road keeping up with traffic in 60mph zone.

Requires module replacement at $680 and 7 days to get part. Unsafe to drive with no reliable speed measure.

I own a 2003 Chevrolet 1500 z71 ext cab pickup. On Dec 23, 2004 the speedometer would not decrease its reading, even if the vehicle was at a complete stop.
