Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

My dash cluster is malfunctioning. It says my car is overheating. Had it worked on and after found it was a known cluster problem. The speedometer is not accurate and I got pulled over for speeding. Next the cruise control went out. Now the gas gauge is next. Checked on line and GM is aware of these issues but has done nothing. Repair bill is around $500 dollars. Seems unfair to me. Will be traveling on interstate soon hope no one gets hurt due to speed/engine over heating and not knowing/running out of gas on a busy interstate. I thought I bought a dependable car...guess I was wrong.

The headlights on my 2004 Chevy Impala just suddenly went out during night time driving. The only thing that would give me any light was to hold back on the dimmer switch lever. I have since learned that this malfunction has happened to hundreds of owners of Impala. The switch is quoted as costing over $500 and installation another $200. That's alot for a commonly defective plastic part! it's also a very poor design to have all headlights go out simply because the dimmer switch is malfunctioning.

The contact owns a 2004 Chevrolet Impala. The contact noticed that the speedometer was inoperable and she was unable to determine how fast she was traveling. The dealer and manufacturer were notified of the failure however, did not offer any assistance. No repairs were performed. The current mileage was 132,000 and the approximate failure mileage was 100,000.

First my tempature gauge starting reading vehicle was over heating and I had just started the car. Now the needle is pinned at the bottom even when the vehicle is off and the gauge is on the top. Then the gas gauge started jumping. Now it does not read accurately at all, at time is way pass full or doesn't read anything, even when I fill up the gas. Finally the speedometer stopped working or gives false speeds. I have been traveling on the highway over 50-60 and the speedometer reads 10mph. The check engine light now has come on also.

Speedometer does not go to "0" when you stop. You start out at 20 or 30 miles an hour and the speedometer show an inaccurate reading. This is a safety issue. You must rely on your gps device to show your proper speed. There should be a recall on the instrument cluster as there are a lot of complaints.

I have a 2004 Impala. It only has 36,000 miles on it. I have kept it well maintained and is great shape with low miles. The gauge cluster on the control panel began acting crazy as many other postings I have seen on the internet. The speedometer and temperature gauge is screwed up. It reads 100 when I'm guessing 40 or 50 mph or 10 when I'm around 35 or the total opposite. I can reset it temporarily by turning the key on and off until the speedometer and the temperature gauge reaches zero. It is sometime ok for a short while. But it definitely will go wacky after I go over 50 mph or if I go over 60 mph hour on the interstate. Then I have no speedometer until I try to reset it and sometimes it takes me days to get it back to only temporarily working. I noticed this happening in 2009 when I got the car from my brother after he passed away. The car at that time only had around 28,500 miles on it. But as times goes on, the issues are getting more prominent and worse. There are sometimes I have to wait a day or two to even get it back to reset. I have called the local Chevy dealer laria Chevy in rittman, Ohio where my brother had purchased the vehicle from originally. I told the service manager told 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 to $650. I believe this is a total rip off by Chevy!! this is not an isolated problem, considering the mounting number of complaints I have already read on the internet. There is definitely a safety factor involved and I can not believe there was no recall by Chevy or by the NHTSA board. I am so displeased with this vehicle that this will be my last Chevy I will ever buy and I have voiced my displeasure with several of my friends. I will go back to a dependable Honda car which I drove for 12 years and never had issues with it as I have had with this Chevy!!

Impala 6-cyl

  • 60,000 miles
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.

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.
