Vehicle speedometer is floating. Sometimes I am doing zero mph. Then sometimes I am doing 120mph. This is a safety issue and something needs to be done about it. I never know how fast I am traveling down the road.

2004 Chevrolet Impala ls 3.8 V6 my wife's car started having problems with the instrument cluster not showing the correct speed or tachometer readings. I went on some site to research the problem only to find that this is a problem with this make of auto for quite some time. In most cases Chevrolet has told the owners that the must pay for repairs costing as much as $1000. This is unacceptable. If there a systematic failure of this system on the Impala then Chevrolet needs to correct it before someone thinking they are driving with-in the posted speed limits when in fact they may not be as there is a serious injury. Also found that there have been recalls on these cars. I am in the process of checking the partrs on my vehicle to see if it in fact was affected. I have never been notified wether it was or was not part of any recall. [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Chevy Impala 2004 with less the 60K miles. Speedometer, not accurate, shows incorrect speed, either too fast or too slow or no speed when moving. The engine temperature gauge, started with needle not returning to default position when engine is cold. Now temperature gauge shows high temperature when in fact engine is cold. The gasoline gauge stopped working.

I have a 2004 Chevrolet Impala that has a huge amount of issues within the dash. My car shows that it is running hot when it is not. It also shows it has no gas when the tank is full. The newest issue is that my speedometer is now stuck on 80 when the car is parked and is well over the 120mph when I am driving on the highway. I have no idea how fast I am going. This is the worse of the three because I or someone could be injured by this. To have people on the road with unsafe vehicles and the manufacture not be held responsible is ridiculous to say the least. There are so many people having this issue and I am not sure why this has not. Been recalled. I hope it does not take someone being killed before someone does something!

2004 Chevrolet Impala - speedometer gone haywire 1. first, the turn signal blinker failed. Blinker did not work, but turn signal stayed lit and indicated I as turning. 2. next, the heat turned to air conditioner mode. I had to switch off the ac back to heat. 3. last, on a 45 mph road I was traveling at 45 mph and suddenly my speedometer shot up to 75, despite my speed being maintained at 45 (per the gps unit). I had to get onto the freeway where it is 60 mph. Used my gps in order to go the correct speed limit. At a stop light and when parked, the speedometer now registers 75 mph. Others have reported this problem too at: www.carcomplaints.com/Chevrolet/Impala/2004/accessories-interior/speedometer_gone_haywire.shtml.

Speedometer was giving erratic readings and now has stopped working all together. I replaced speed sensor and it did not help. I have to look at gps to find speed or estimate based on flow of traffic. This appears to be a common issue based on the complaints I have seen on internet and GM should replace the speedometer/instrument cluster.

I have a 2004 Chevy Impala, the speedometer is running 40 miles over what the car is really moving. I was almost rear ended because I was not going fast enough on the freeway. Something is faulty in the dash board. I am not sure if there is a recall on this for GM cars.

First the fuel gauge stopped working and was like that for a couple weeks, now it is working again, then speedometer went crazy, traveling at approximately 55 to 60 mph, speedometer is reading 15 to 20 mph then drops to 0 it has done this before, so I went online to see if anyone else was having the same problem and if there was a recall. I found numerous complaints from other owners. I was wondering why there is no recall out there since there are so many complaints this could really be a serious issue.

2004 Chevy Impala: Speedometer malfunctions, usually jumps to over 120 mph at freeway speeds but can read low or high. When stopped it currently is stuck at 67 mph. Tomorrow it may be 35 who knows. I feel this is a major safety issue.

While traveling in 2004 Chevrolet Impala, speedometer needle will freeze and not move or move to various speeds while the car is traveling at a steady speed. This failure is occurring almost daily, and started as a once in about a month episode. Vehicle will need $900 worth of repairs to fix speedometer.

The speedometer on my 2004 Chevy Impala does not accurately tell what speed I am traveling. It randomly sticks at a speed, sets the baseline at a random speed and reads in the 100 mph range when I am at a stop sign or going through residential neighborhoods. I have not fixed this problem as the dealership quoted a $400 repair and I cannot afford a costly fix to a problem that is not my fault. This occurs almost daily and at random times, sometimes during short trips, other times during long trips, both in the morning and night, does not matter how fast I am traveling or the temperature outside. I live in new england and this has happened in every season.

I have a 2004 Chevrolet Impala ls with an automatic transmission 3.2 V6. The speedometer will stay on 70mph at rest or more then go over a 120mph when traveling. Once in awhile it may resume back to normal. It is a huge problem in not letting you know exactly what rate of speed you are traveling.

Instrument cluster failure on 2004 Impala ls 6cyl 3800 tach quit working, temp gauge quit working, fuel gauge quit working or working sporadically.

- Findlay, OH, USA

On several 2003-2006 GM vehicles, the speedometer stops working (the needle stops moving). The fix requires that the entire gauge cluster be replaced from within the dash. The speedometer typically fails shortly after the vehicle's 36K-mile warranty expires.
