The speedometer will at random register that you are going faster than what you are. This creates problem on the road and cause someone to break because of fear.

I have an 2005 Chevrolet Impala with 45,000 miles and night time driving is very difficult and scary as the headlights will go off without warning and you never know when it will happen. I have had it in the shop multiple times and they have replaced parts and still has not fixed the problem. Now the speedometer has quit working and is stuck on 140 miles an hour.

Speedometer began losing speed, I.e. began dropping, with cruise control on. No loss of road speed noted, dis-engaged cruise control and continued with flow of traffic. Speedometer continued to fall eventually reaching 0 mph. Speedometer began working again after shutting vehicle off. Currently it will be very slow getting to 0 mph when vehicle is fully stopped. Very erratic operation overall. Contacted GM customer care, they said it sounds like a bad speedometer stepper motor. Informed that it is not under any recall. Currently not repaired due to high cost of replacement. Note: Vehicle is a 2005 Chevy Impala, out of warranty due to mileage (58,000).

Speed sensor went bad at 45,000 miles on a 2005 Impala. Repaired the problem and found it caused the instrument control panel to be in-operable and need to replace that. Wipers also park in upright position. No defect codes found.

While driving my 2005 Impala ls with only 38,000 miles on it, the speedometer dropped to zero then back to well over the limit. Lately it is all over the place. The tachometer is doing the same. I took the car to the dealer and they said they would repair it but would cost me over $600. These things are covered on the pickups and SUV's to 70,000 miles but not the cars. Why not"?? it's almost like Chevrolet considers it's car owners "not worthy". what's up! Chevrolet??"

Speedometer on my daughters 2005 Chevrolet Impala stopped working after 50,000 miles. Chevrolet has refused to pay for repairs even though they extended the warranty for trucks and SUVS with defective speedometers to 70,000 miles. I think Chevrolet should pay for repairs to all Chevy owners with defective speedometers, especially on a vehicle only two years old.
