Just driving down the road no specific road just normal driving and all of a sudden the speedometer either goes up or down does not have correct speed sometimes it will go back to normal after about an hour and sometimes after thirty minutes or after you shut the car off and restart. It happens about twice a week I have not replaced any parts as of yet trying to figure out what the problem is for sure. I am reading online that many people are having this problem and it is the gauges need to be replace and that there is a recall on Chevy trucks but mine is a 2004 Impala and as of yet there is not one and there are many people very angry online regarding this matter and want a recall as soon as possible because the cost is about 600 - 800 dollars depending on where you go so they are using gps systems for there speed instead of getting it repaired since the cost is so high.

My speedometer is out of whack, also the tach doesn't read correctly. You never know how fast you are going. This could lead to a serious accident. Going around corners or driving in a school zone. Somedays it works for a little while and some days not.. it reads 90 miles an hour while your going slow.

The contact owns a 2004 Chevrolet Impala. While driving approximately 30 mph on normal road conditions, the speedometer displayed an inaccurate reading regardless of the speed being traveled. The failure occurred intermittently in cold temperatures. The failure was related to the stepper motor. The vehicle has not been repaired at this time. The failure mileage was 30,423.

Speedometer malfunctioning. There were no known specific activities that led to the occurrence of this issue. About two months ago, during a road trip, I noticed that I was driving slower than normal traffic but my speedometer stated I was doing the speed limit 65 mph. When I looked at my gps, it stated I was doing about 47 mph. When I sped up to 65 mph according to my gps, I was in the flow of traffic. After I stopped, it "reset" itself back to zero when the car was idle. About a week ago, it won't reset anymore. When the car is off, the needle points straight up. When the car is idle, the needle goes to about 80 mph. When I'm driving, it goes past 120 mph. So I'm constantly using my gps in order to maintain the proper speed. I've begun to research on the internet any information on this issue. There are many complaint websites where various Impala owners (2004-2006) that are encountering the same issue. I'm not willing to replace this part; I have over 126,000 miles on my car. But there were other owners who did not have nearly as many miles as I have with the same issues.

2004 Chevrolet Impala speedometer malfunction. Indicates very high speed (90-100 mph) even when barely moving.

Impala 2004, speedometer stop working.

Speedometer has a mind of it's own sometimes it works, some times it doesn't, this is a real safety concern when I cannot tell the true speed in which I am driving.

- Stover, MO, USA

Speedometer was sitting on zero, after stopping it started moving, but was jerky. The speed sensor has been replaced. This did not fixed the problem. The tachometer is not working properly either so unable to tell what my speed is in the car.

Instrument panel malfunction has been a problem with my 2004 Chevy Impala for 3 yrs now. Like everyone else, can't afford to get it fixed. In winter, the speedometer rarely works at all and the temperature gauge just goes wherever it wants. However, I have not had any problems with the gas gauge, but not saying that I won't. I really do believe that a recall should be made for this problem.

The speedometer instrument cluster is not working properly. My speedometer does not work most of the time in cold weather, and always moves erratically, providing inaccurate measurements of speed. My tachometer does not work at all after several months of erratic movements and inaccurate readings.

Speed-O-meter needle pegs out and wanders inadvertently. Just happened one day. It is a continual occurrence. Some days it seems to work kind of, and at other times it moves very abruptly on the dial and never smooth like it should. It has been the cause of being pulled over on 3 occasions in the last month due to lack of knowledge of my vehicles' speed. There is no way to determine the vehicles' speed without it (and without a gps device or something similar).

The speedometer on my 2004 Chevy Impala went crazy, stopped working. Through much research, there are hundreds, maybe thousands of this car with this problem. GM says there is no recall as of now and the problem is $400 to $600 to fix. I have been told it is the gauge cluster. It is a 4yr old car with 68K miles on it, I feel that GM should take responsibility for this problem. There is a recall for the Chevy trucks and Tahoe's for that year, but not the Impala's... they use the same part number in the gauge cluster, so why shouldn't the Impala have a recall on them? this is a costly repair and a very dangerous part to have go out. I've read that people cannot afford to repair their cars, so they are driving them with no speedometer. I am doing this also, having to save up to have it repaired. So now we are guessing our speed, hoping not to get speeding tickets. Please help us get GM to help out.

My 2004 Chevrolet Impala is having major issues with the whole interior gauge panel. I have read thousands of the same complaints about Impala models 2003-2006, and other Chevy models. The gas gauge has went completely out and the mph gauge randomly goes haywire reading the incorrect speed, or no speed at all. The most common response is that GM has a defective stepper motor in the instrument cluster. This problem ranges in model and mileage and costs up to $600 to fix. This is a dangerous safety issue, not to mention a huge pain. GM really needs to step it up and recall this obviously defective piece. I have yet to repair it as I feel its not my fault and they need to fix this defective safety issue. I know I'm not alone in this complaint.

Speedometer on 2004 Chevy Impala with 41K miles is defective. Started sporadically, now it is all the time. Speedometer may say I'm moving at 50 mph when at a stop or over 100mph on a city street. I have not had the defect fixed yet.

Vehicle speedometer suddenly quits functioning. Speedometer suddenly shows high speed (example 120 mph) when driving highway speeds (verified at 70 with gps). Speedometer remains stuck in this position. I was able to clear the error after returning home and cycling the ignition from off to on several times. This occurred on July 2009 also under the same circumstances.

I just bought an Impala 2004 this January. I an on a fixed income and cannot afford to make many expensive repairs. When we had a cold snap, my car was making a whirring noise and I discovered that my speedometer was on zero. When the car warmed up, the speedometer started to work again this happened on the remaining cold days and then stopped. 6 months later, the speedometer is either on zero or just not working properly. Luckily, I don't travel very far, but this is very unsafe. I have read on the internet that Chevy recalled the speedometer for the Tahoe, but not the Impala. I again am on a fixed income and cannot readily get this fixed, but unfortunately will have to shell out $500 for a part that Chevy put in knowing it's defective.

Gauge cluster on 2004 Impala fails. Speedometer goes out and driver doesn't know how fast they are going. Have heard many similar complaints with other gas gauge going, tach, etc... mine was just the speedometer - would sit at 120mph when only going 30. Continued to do so until had the entire gauge cluster replaced at a local mechanic shop. Have read many reports online about other Impala owners having same problem. If it is that widespread and so known about for how many years, why hasn't there been a recall for the Impala like they did for the Chevy/GM SUVS and trucks?

- Hibbing, MN, USA

Speedometer just quit working the way it should with out warning... giving from no speed mph to going exceedingly much faster then what you are going.. ie~ at a stand still registering at over 75mph... to driving approximately 50mph and registering at below 0 mph.. this has been what has been going on in the 1 day since the problem has started; on August 20 2009.

Speedometer and gas gauge are not working. They suddenly stopped being correct. Sometimes they show I am going 100 while in park, or 75 while going 30. The gauges freeze and stay that way for several days. I have read online that many others are experiencing the very same thing.

No single event. 2004 Chevrolet Impala speedometer not working properly. After some research, found out several people are having the same issue. Just last week, I was pulled over for speeding, the cop let me off with a warning but said next time, that excuse won't cut it. The problem won't fix itself, and the dealership quoted around $450 to repair the speedometer cluster. I can't afford such a costly repair when I need to buy new tires. One safety priority at a time I guess.
