Speedometer frequently indicates the wrong speed. The speedometer needle got stuck at zero mph when outside temperate was about 20 degrees Fahrenheit. Ever since that time (for 3 months now) the speedometer needle will frequently stick or jitter as vehicle speed changes. When speedometer needle is stuck it fails to reset all the way to zero when car is started. It only moves counter-clockwise a little bit when starting the car; it does not move back to its reset position. The reset problem could be compounded by a programming problem with the signals sent to the stepper motor. The fuel gauge needle can be heard and seen during starting of the car to swing the full range of the fuel dial to reset itself. The speedometer only moves a little bit counter-clockwise during startup; not nearly enough to reset to zero when it gets stuck.

Problem is speedometer. Driving on highway at 60 mph, as sun was setting, speedometer slowly went 60 to zero or a low number (over 5-10 minutes) with no actual change in speed. This happened on several consecutive days. Currently, for many months, speedometer is not accurate. E.g. going about 40 mph, reads 20 mph. E.g. going about 35 mph, reads 120 mph, repeat 120 mph. E.g. car at standstill, speedometer reads 120 mph. E.g. going 40 mph, reads zero. Often shows correct speed then slowly goes down with no change in actual speed. Very dangerous on highway at night not knowing how fast you are going. Searched internet, many similar complaints. Problem - possibly stepper motors. Need recall.

Event: Use the brakes. Failure: Front end shakes. Repair: Replace rotors. Event: Drive at any speed. Failure: Speedometer gone haywire, says your going 20 when you are going 70? repair: Rebuilt instrument cluster. Event: Any time engine running. Failure: Temp gauge haywire. You pull over thinking your car is overheating; it's not. Repair: Rebuilt instrument cluster. Event: Any time engine running. Failure: Fuel gauge haywire. Don't know how much fuel you have, could run out of gas (did not happen to me). Repair: Rebuilt instrument cluster. Event: Using blinkers. Failure: Blinkers either don't work when activated, or flash randomly. Repair: Replace blinker/hazard module. Event: Turning ignition key failure: No crank, no start - security light on. Wait a while, car starts like nothing happened. Repair: Bypassed and disabled security 'passlock' switch. Event: Using wipers/rain. Failure: Windshield wipers stop in middle of windshield, continue after turning off, or don't come on when switch turned on. Repair: Replace wiper motor & pulse board. Event: Stop at intersection with engine running failure: Engine surging and stalling. You must keep your foot planted on the brake so that you don't run into the car in front of you. It stalled out of state in an intersection. Repair: Replace mass air flow sensor (maf). This most recent maf problem was the last straw. This car has other non-safety related electrical problems, as well as the normal wear items that you would replace on a 'real car'. this car is a rolling electrical disaster. This car is a money pit, just like its manufacturer. Good luck with that Chevy volt.

Instrument cluster failed. Tachometer, speedometer and temperature gage give false readings. Speedometer sticks and indicates 65 mph when vehicle is stopped. Tachometer randomly indicates rpms varying from 0 to more than 8000. Temperature gage indicates randomly between minimum of 140 and maximum of 260 degrees.

I have a 2004 Impala. It only has 41,000 miles on it. I have kept it maintained. Recently the gauges on the control panel began going crazy-flicking back and forth and the check engine lite would come on. Now the speedometer is whacked out. It reads 100 when I'm guessing 40 or 50 mph or 10 when I'm around 35 or the total opposite. I called the local Chevy dealer, serviceman and told them of the numerous complaints I had read on this problem. He informed me there was no recall and the cost to repair it would be around $550. I believe this is a total rip off! this is not an isolated problem, considering the mounted number of complaints I have already read. This was my 1st Chevrolet, I will never buy another one!

Several times, I have had my 2004 Chevrolet Impala just randomly not start. After researching the problem, I have found that it's the passlock system installed in the vehicle. I'm no mechanic but know how to research and the amount of people with these same issues is overwhelming! it appears that there are some nickel pins that were used in the ignition switch that are very picky to oxidation levels to the point of being faulty - the smallest wear and tear or corrosion of these pins can start this problem. It happens with no warning as well! this may not seem like a safety issue, but put yourself in my shoes. I live in North Dakota, and when something like this happens in -40 degree weather it becomes a safety issue. Something needs to be done about this problem that appears to span many years and models of GM vehicles.

The gauges on my 2004 Chevrolet Impala ss are acting erratically. The RPM at idle sits at about 3 and when I'm in drive if ranges from 4 to 5 with very little acceleration. The speedometer has started doing the same thing when traveling at about 35 to 40 mph the speedometer registers 140 mph. When turning the car off the gauge indicators don't go back to their designated starting positions.

The speedometer ( component 1 ) has failed in the vehicle. It began by operating erratically on the date entered above and has progressed to not working at all most of the time or displaying the wrong speeds I.e. 70 mph while sitting still. The tachometer ( component 2 ) is also showing the same signs to complete failure by displaying unrealistic engine speeds while at idle. I contacted a dealer who ran the VIN and found no recalls. I however have researched this matter on the internet and have found numerous complaints of the same nature that appears to point to the stepper motors used in the instrument clusters by GM to be the problem. It also appears that GM has recalled several models of the same era due to this problem but not the Impala line. I fail to understand how the same problem is recalled for some but not all affected models.

The tachometer stopped working a few months ago, it goes up and down and all around and the speedometer began not working at all one day then it was ok for a few weeks and now it seems to be stuck between 40 and 120 even when the car is off. I have no way to determine my speed.

While driving a consistent speed, speedometer will fluctuate from stuck at zero to 120mph. Happens constantly. Fuel gauge fluctuates also and doesn't always work. If using cruise control while speed appears correct, the Impala will automatically increase its own speed while the speedometer does not change leaving an unsafe opportunity open for very tragic accidents to happen. I cannot believe that my 2010 Pontiac vibe has had 3 recalls and this Impala has not had any for the instrument panel. Do people really have to die or be injured before something is done to protect us?

- Summersville, WV, USA

At highway speeds, speedometer began reading erroneously over 100mph before oscillating between 0 and 100. It settled at 0 for several hours but then returned to 100 with vehicle speed approximately 65 mph based on other traffic. Vehicle was turned off and back on with no change in symptoms. Problems persist.
