In addition, the windshield wipers failed sporadically, the rear passenger tail light was poorly illuminated, and the battery failed spontaneously. When the failures occured, she smelled a burning odor as if the wires were burning. The vehicle has not been inspected to determine the cause of the failure.

My speedometer is not functioning on my 005 Impala and has not for months. It will say you are doing 100 when parked and never comes back down unless you keep restarting then engine to make it "shock drop" back down. The dealer wants $400+ to replace the whole unit. It seems that from just a little research online that this is an ongoing issue with numerous Impala's manufactured since '04.

Speedometer does not work on my 2005 Chevy Impala and GM has admitted this is due to faulty parts. This is a dangerous situation since it is impossible to determine accurate speed.

I have a 2005 Impala ss, the vehicle has starting problems which began at 8,000 miles. If the car sits more than two days without being driven the battery goes dead. There is a serious electrical drain on the battery. I took the car to the dealers service department on several occasions, they tell me that they can find anything wrong. At one point they kept the car for a week, then told me that I must be doing something wrong because they can find anything wrong with the vehicle. The car now has 17,000 miles, and I continue to still have the electrical drain. I have had to purchase two new batteries since owning the car. I have to carry a portable power source in the trunk, to jump start the vehicle. This is not right and should not be happening. The electrical problem should have been solved by now. I have been a loyal Chevy owner for fifty years, and this is the way I'm rewarded. The manufacturer and the dealer still have not learned that professional customer service is paramount. I may never buy another GM car.

My speedometer does not work it started out reading the wrong speed now it is pegged all the way out the needle lays on the D for drive. I feel this is a safety issue due to never knowing how fast you are going.

- Troy, PA, USA

Speedometer said I was doing 87 mph when car was shut off and in park. Took car to dealer, had instrument cluster replaced. Also had them check pop in the steering( made noise when I bought it from dealer with less than 31,000 miles on it. Dealer replaced instrument panel cluster, steering shaft and cruise control sensor. ( cruise control would just shut off and work periodically.) it was really just an adjustment on the brake sensor switch that needed adjustment. Had to take car back for the adjustment to brake pedal sensor.

I have a 2005 Chevy Impala with 45,200 mile on it and from day one I have had a electrical problem of some sort every time I am driving all my lights will go out, even all my panel lights inside. I have to flick my brights on and off so they will come back on. Some times this happens two or three times a week. I have had it back to the Chevy dealers twice and they say there is nothing wrong. What do I do? thank you.

- Marshfield, MO, USA

The contact owns a 2005 Chevrolet Impala. While driving between 5-25 mph, the speedometer and the temperature gauges moved up and down. The contact took the vehicle to a personal mechanic and was informed that the failure caused the vehicle to need coolant. He feels that the vehicle is unsafe because the thermostat rises due to the vehicle overheating and the speedometer failing. The current mileage was 68,000 and failure mileage was 64,000.

This past summer in June, the speedometer would read 40-80 mph when stopped/idle. Problem subsided after a few weeks. More recently, within the last 2 weeks, my speedometer in my 2005 Impala would gradually go down gradually during long distance travel (100mi+) on the I-10. To me, this is a very dangerous issue with the car.

My 2005 Chevrolet Impala with the V-6 3800 engine has developed a problem where the speedometer has ceased to work properly. It either does not register any speed at all or it fails to return to zero when the car is stopped. In doing some research online there are numerous postings on edmonds.com regarding this defect. I have not been able to find any recall notices for this defect from General Motors. It is my opinion that this defect poses a serious safety concern because motorists like myself are unable to determine accurately the speed at which the vehicle is being operated. This poses a variety of potential dangers to the motorists operating the vehicle with the defective speedometers, other motorists on the roadways, pedestrians, and first responders at traffic accidents.

The speedometer reading on our 2005 Chevrolet Impala is inaccurate/malfunctioning. Sitting still at the stop light it reads 100 mph and other times 30 mph pulling out of the driveway it reads 70 mph and at other times it points straight down at the neutral indicator with no reading at all. Our vehicle has 76200 miles on it and he contacted the local dealership which in turn told us that GM would pay for the problem on vehicles with less than 80000 because it was so common but General Motors headquarters said since they were filling bankruptcy they would not pay for it and we were on our own. The local dealership said they could fix the problem for $500 to $700 dollars which is unacceptable. GM wants a government bailout at their customer's expense and their equipment malfunction. This is unacceptable!

Gas gauge reads empty when car was just fueled. Speedometer at times reads 0 when I'm driving on the freeway. At times the speedometer will read 65 yet I'm zooming past cars so who knows what speed I am going.

- Reno, NV, USA

I have a 2005 Chevy Impala.. for past two weeks my speedometer has been reading incorrectly. I was on the interstate doing 70 mph but it felt more like 50. The problem stopped for a couple of days but yesterday.. it took another turn. I was doing 35mph but the reading showed 0mph. It is now pointing in the up and down position and will not move. I have checked other forums and found that there are many many other Impala owners experiencing the same problem. This seems to me to be a factory default. There is a major possibility for serious accidents occurring due to this problem.

- Ft Hood, TX, USA

I own a 2005 Chevrolet Impala with approx. 86,000 miles on it. My speedometer is going haywire(not consistent at all) and I am unable to correctly tell my speed. I know there are quite a bit of other GM vehicles with the same issue because there is a blog on the internet about them. I am concerned about this due to the fact that I have a 3 year old son and my wife with me a lot. GM said they will not pay for this problem to be fixed and a lot of people can not afford it($500-$800). I just hope GM will take responsibility and fix this issue at free of charge to the consumer before someone gets injured or even killed.

- Beaufort, SC, USA
