Recently reported ELECTRICAL SYSTEM problems on 2004 Chevrolet Impala

Speedometer and oil pressure gauge goes haywire. *tr

Tl*the contact owns a 2004 chevrolet impala. while driving well below 40 mph, the speedometer read 65 mph. the contact turned off and restarted the vehicle and noticed that instead of being defaulted at 0 mph, the speedometer began at 60 mph. the failure occurred each time the vehicle was started and would display different speeds. the contact called the dealer and the service manager stated that there was a failure in the instrument cluster. the contact would have to pay for the repairs. the vehicle has not been repaired. the failure mileage was 11,000 and current mileage was 11,400.

The speedometer and the tachometer pegs while driving. *tr

Speedometer stuck at 20 mph. *tr

Speedometer failed after approx. 60,000 miles on my 2004 chevrolet impala ls. it is inaccurate and inconsistent, often reading 30-60 mph when i am stopped at a light and often reading over 90 mph when driving below 40 mph. at times, the needle jumps erratically and gets stuck outside the normal range, such as pointing to a gear indicator on the display rather than to a speed on the dial. *tr

The speedometer doesn't work sometimes. when it moves it doesn't move smoothly, but it jerks up and down, often indicating an incorrect speed. the car has low miles on it and the tcc solenoid and another solenoid regulating line pressure in the transmission has failed, requiring replacement. *tr

We purchased our 2004 impala new in may of 2004. there are currently 56,000 miles on it. the speedometer acts crazily and we also have the noise and vibration the steering column. the dealership says the steering shaft will cost at least $100 and a new instrument cluster $300. that doesn't include the cost of labor and state sales tax! these defects need to be addressed . i am almost fearful to let my wife drive this car. after reading all these complaints, i can't believe the government is failing the american consumer trying to buy american products. no wonder the foreign car companies are eating detroit's lunch! *tr

Speedometer is not working correctly (sticks/doesn't move). apparently this is a very common issue with this vehicle, but chevy has issued no recalls. *tr

There were no events leading up to the failure. my wife was driving the car and the speedometer just stopped working. the speedometer would not show the correct speed. the needle would point directly down (not at 0) and then move counter clockwise when the car accelerated. *tr

Driving home, suddenly the speedometer stopped working and passed 60 mph and was increasing while i started accelerating from complete stop. it reached 110 miles till my next stop, was stuck at 110 again and going up again when i started accelerating till the arrow was pointing south and stopped moving. *tr

Speedometer is stuck at 55mph while car is off. when driving the speedometer will read 90mph when driving 30 mph. temperature gauge works sporadically. called gm and was told that my car is not part of the extended warranty (recall in other words). i was told to contact my dealership for repairs (at a cost of over $500.00). many other vehicles from the same year are covered. we need to keep the pressure on this company. *tr

The speedometer on my car is giving false speed information, by as much as 100 mph. this is a very unsafe condition. i am aware of many other gm vehicles with this same defect. *tr

Speedometer failure, gives me false readings, gm said i had t opay $600 to fix it, car only has 70,000 miles, many others having this same problem, it is a major safety issue, we all can't afford to pay for this issue, which is faulty from the factory, gm should recall the vehicle to fix. *tr

Tl*the contact owns a 2004 chevrolet impala. while driving 54 mph, the speedometer worked intermittently for two months until it finally failed. a friend of the contact, who owned the same year, make, and model vehicle, was experiencing the same failures. the speedometer has not been repaired. the vin was unknown. the failure mileage was 54,000 and current mileage was 55,000.

Speedometer not working correctly. it shows speed of 90 at about 45. reads 60 at a stop. many complaints found on internet. serious safety issue. *tr

Tl*the contact owns a 2004 chevrolet impala. while driving approximately 15 mph, all of the instrument panel gauges stopped working. prior to the failure, the heater unit shut off without warning. in addition, after several attempts to start the vehicle, it finally started and drove roughly. the vehicle was taken to an independent mechanic and it was discovered that the failures were related to the security system in the control panel. the vehicle was repaired for the malfunctions. recently, the driver message center and horn were not operating, and the transmission was not running properly. the vehicle has not been repaired. the failure mileage was 13,000 and current mileage was 27,000.

The speedometer of my 2004 chevy impala goes out. while driving down the road it will start climbing even though my speed has not changed. i may be going 40 mph but the speedometer reads 120 mph! the gas gauge will also read wrong and my temp gauge just plain doesn't work. this has been going on for over 2 years now. gm says it's not a recall issue. it can be corrected for awhile if we disconnect and reconnect the battery, but the fix is short lived. we have not yet had it repaired, the cost is over $400. we plan on having it fixed soon. i constantly feel unsafe driving this car when the speedometer malfunctions. i feel gm should be responsible for the cost of repair. *tr

The tachometer, speedometer and the temp gage are all out of the car started in the winter of the year that we bought the car and slowly one by one each gage went out. *tr

Intermittently failing speedometer in 2004 chevrolet impala. *tr

Speedometer and tachometer are acting erratic. gauges are all over the place, either not working at all or is giving me a false reading. if i am driving at 35mph the speedometer might be reading either 15 or 35 or 75, it changes all the time. *tr

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 $450.00 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. *tr

I have a 2004 chevy impala. recently the speedometer needle gets stuck and never gets back to 0. chevy has failed to realize this as a recall and instructs all parties to pay $500 to fix this issue. i would be helpful if an agency like this one steps in and has chevrolet take ownership to this very serious and possible life threatening hazard. *tr

Speedometer and tachometer drop to zero while driving after 30 minutes. *tr

My 2004 chevy impala has a gauge problem. none of the dashboard gauges work. i don't know how fast i am going, how much gas i have or if my car is over heating. its scary driving this car! *tr

My speedometer stopped working in my 2004 chevy impala out of the blue. it is still broken and will give me false readings every time i am driving. i can no longer tell how fast i am driving. i have done nothing to correct the problem but i do know other chevy models with the same problem. *tr

On december 24, 2007 i was driving my 2004 impala along a highway when i noticed the speedometer climbing higher than the speed i was actually going, this continued until the speedometer was reading in excess of 200 kmh. when i reached my destination about 15 minutes later i turned off the car hoping the speedometer would reset to zero which it didn't. i was unable to reset it until the next morning when i turned the ignition to on and off about 15 times before the needle returned to zero. this has happened several time now and it look like i will have to eventually take it to a dealer to have repaired. there is approximately 123,000 kilometers on the car. *tr

My wife and i own a 2004 chevy impala which we bought new from gm. the car has 43756 miles on it, and the speedometer has completely quit working. it currently reads 107 mph even when the car is turned off. the other gauges started acting strange, but when the key is cycled, they go back. however, the speedometer does not budge. this started the day before christmas, and has continued ever since.*cn

Normal driving, speedometer goes to 120mph and stays there. i stopped the car and shut it off. turned it back on. still at 120 mph. called the local chevy dealer and they said they never heard of such a thing. i checked the web and find its a common problem even though chevy will not acknowledge the issue. dangerous driving without a working speedometer! *tr

2004 chevy impala instrument panel failure. consumer states that the cruise control set to 70 and driver was only moving about 40 mph. speedometer read 140 mph and consumer was not going that fast. *kb

Speedometer will give erradic readings. i first noticed it on december 22 while driving down the highway; speedometer suddenly began to read 110 mph. at a standstill, speedometer was reading 50 mph. it has done this on two more occasions, with the last date being january 4, 2008. i have been able to get the speedometer back to zero while being parked, but i would have to turn the vehicle off and then turn the ignition to "acc". each time i did this, the speedometer would go down approx. 5 mph so i continued to do this until the speedometer read zero again. i have been told it is probably a sensor issue and when i did research, i found 40 addtional complaints over the same thing and was reading about a potential class-action lawsuit in seattle due to speedometer failures. *cn

Speedometer is broken and the safety i put myself in everyday because chevy cant replace the speedometer that should work for a lifetime. chevy cares more about there profit then the safety of their customers then they wonder why toyota is the #1 seller of cars because they take care of their problems i will never buy a american car. *tr

While traveling on the ohio turnpike speedometer suddenly started climbing higher and eventually pegged its self. i stopped vehicle at the next plaza and turned engine off. speedometer remained pegged with engine off. i got home and parked car. the following morning speedometer was still pegged. by turning ignition switch on and off i was able to back up needle to 0 position. speedometer worked alright at lower city speeds until on 12-25-07 i again got on the ohio turnpike to go to michigan. again the speedometer started climbing and was well past 120 mph mark when i reached my destination . again i was able to reset speedometer by turning key off and on. returning to ohio on i75 again the speedometer started climbing and when i got home speedometer was at 120. at this point i took several digital l photographs of needle position and will leave it there until i take vehicle to local chevrolet car dealership to see what the outcome will be. vehicle now only has 23,900 miles on it. *tr

Speedometer stopped functioning properly. erratic readings ranging from -50 to 140mph. doesn't matter if the car is idling or cruising down the highway - the speedometer is always dancing to it's own tune! suspecting the oil pressure gauge will be next, as it varies greatly while driving the vehicle. i suspect this is not normal or accurate. i encourage all others with this problem to report it here. these are the folks who can help us get a manufacturer's recall, and have the defect fixed from gm's pocket - not your own. *tr

Tl*the contact owns a 2004 chevrolet impala. while driving at an unknown speed, the temperature for the engine failed. one month later, the speedometer failed. the vehicle has not been diagnosed by a dealer. the fuel system was unknown. the current mileage was 62,500 and failure mileage was 61,000.

The speedometer and other gauges on my instrument cluster went haywire. then the speedometer stopped working completely. the instrument cluster had to be replaced. *tr

Speedometer failure on my 2004 chevy impala. *tr

Like many impala owners before me, the instrument panel on my 2004 impala has failed after 3 1/2 years and 60,000 miles. it started out with the speedometer and then the temperature gauge went. this is a serious problem as you have absolutely no way to tell how fast you are going or if your car is going to overheat. vehicle was repaired at a gm dealer and gmc was contacted and refused to cover the cost. *cn

Speedometer and temp gauge sticking and will not reset - reading excessive speed or temps. *tr

My instrument panel also went out in winter of 2007. called gm directly who refused to help with this problem. my father in law owns an avalanche and received recall notice for the instrument panel for his truck and other large suv's that are made by chevrolet. the years covered included 2004. if gm knows that the instrument panels were bad for other models, why haven't they been recalled for the impalas. my car did the same thing; driving approx 40 mph and car read 75 mph. the speedometer read 120 mph on the highway that day when cars were flying by me. this is most definitely a safety issue. unfortunately, gm seems to be waiting for serious injury or death before recalling the bad parts. this goes along with the steering column shafts being bad also. what a joke!! i too will never purchase another american made car as long as i am able to drive. i had to take gm to court over my car due to the car being in the shop approx. 25 times for repairs before it was 4 years old. my whole car has basically been replaced (including the instrument panel and steering column shaft) except for the slipping transmission now. i take very good care of my car as i have the indy motor speedway ss. paid a lot of $$ for nothing. it's no wonder gm is going under. their cars are junk and they don't stand behind their products. what a shame. hopefully no one has serious injury due to all the safety failures with these cars. *tr

2004 chevrolet impala ls with approx 82,000 miles. noticed two weeks ago that the speedometer gauge is not working properly. it will go from 20 to 120 with the actual speed not changing. very dangerous on the highway and with our ice and snow. i have no idea how fast i am actually going. i have read about several other individuals having this exact same problem with the 2004 impala's. there is no recall to fix the problem, and the gm dealers want approximately $400 dollars to fix this. this is a very serious problem, and i believe that an investigation should be done on the 2004 impala to show this is a common problem that gm should take responsibility for. *tr

Tl*the contact owns a 2004 chevrolet impala. while idling, the speedometer malfunctioned and indicated 30 mph. the dealer stated that the speedometer needed to be replaced. the vehicle has not been repaired. the failure mileage was 55,100 and current mileage was 55,560. updated 02-19-08 *bf updated 02/19/08 *tr

While driving on the interstate, noticed that the speedometer was stuck at 65mph, regardless of speed. when turned off, the vehicle still read 65mph. was unable to determine proper speed. noticed that the vehicle reset the speed 5mph lower each time the ignition switch was moved from off to on. multiple cycles of turning the ignition switch on and off finally reset the speedometer to 0mph. don't know if this is only a temporary fix for a problem that will probably get worse. although not a serious issue, the tachometer does the same thing. *tr

While applying the brakes for the first time after start up at low speeds (less than 20mph) the antilock brakes kick in when not needed. for about 2-3 seconds, there is extremely reduced braking ability. after this initial time period, the whole antilock braking system shuts down and also turns off the traction control system. once the shutdown has taken place, the car's braking system functions as if there was no antilock brakes on the vehicle. took car to dealership which indicated that the wheel sensor was bad and could be replaced for $600.00. also while driving on the interstate, noticed that the speedometer was stuck at 65mph, regardless of speed. when turned off, the vehicle still read 65mph. was unable to determine proper speed. noticed that the vehicle reset the speed 5mph lower each time the ignition switch was moved from off to on. multiple cycles of turning the ignition switch on and off finally reset the speedometer to 0mph. don't know if this is only a temporary fix for a problem that will probably get worse. although not a serious issue, the tachometer does the same thing. *tr

Was driving normally and the speedometer needle dropped from the 12 o'clock position to the 6 o'clock position. it now operates sporadically and is usually 10-15 miles off. working on getting the problem repaired. *tr

Tl*the contact owns a 2004 chevrolet impala. while driving approximately 50 mph and decelerating, the contact observed that the speedometer was providing inaccurate readings. the failure occurs frequently and without warning. the vehicle was not taken to an authorized dealer. in addition, the steering wheel makes a loud clunking noise when making a turn. the vehicle was taken to an independent mechanic, but no malfunctions were found with the steering wheel. the failure mileage was 98,000 and current mileage was 103,000.

The speedometer started getting stuck about six months ago. for about eight months i have noticed that when i turn the steering wheel i hear a noise in the front of the car, like a knock or something. also within the last couple of months i have also smelled gas when i first start the car , my husband could not see any leakage or anything until last week. it was leaking from the fuel regulator valve. now the transmission is starting to shift hard sometimes. i haven't had the money to get it all checked out by the manufacturer but i was wondering if there have been any complaints on any of these things. also i can hear a whistling sound when i press the accelerator. and my husband just informed me that he bought a regulator valve for it and some o rings because something is leaking antifreeze slightly. can you help please!!!!!!!! *tr

I purchased a new 2004 chevy impala in april of 2004. in november 2007, one morning i noticed that i was driving through a parking lot at approximately 70 miles per hour, thinking "it sure doesn't feel that fast." after applying the brake i observed the speedometer drop only to about 50 mph. later that day i found that the only way to get the speedometer back to zero was to turn off the car and restart it several times as the needle would drop about 10 mph each time. once at zero the speedometer appeared to read correctly. over the next few days the problem continued though it was remarkably worse the colder the car was. by now, january 08 the speedometer has stopped reading accurately altogether and has parked itself at the 360 degree mark. this problem has been addressed in chevy and cadillac trucks but gm has been slow to issue any special policies or recalls regarding the cars. the parts (specifically faulty stepper motors manufactured by delphi) by all accounts i have been able to research however are the same regardless of model. this is a safety issue primarily as well as a legal liability. besides this, the issue is certainly a customer relations nightmare. i alone have viewed several hundred complaints regarding the same issue. chevrolet must address this problem immediately with a full replacement of parts and complete warranty. *tr

We had just bought a 04 chevy impala ls it has 54,000 on it. the intermediate steering shaft is bad. we are thinking that it a manufacture defect not to mention that the speedometer is not working properly either. *tr

Speedometer and tachometer started reading erratically constantly. i did not have the ability to know what speed i was going. instrument cluster was replaced at dealership. the old part was not made available, they said it had to be returned to be refurbished. cost: $508.28. *tr

My speedometer has gone crazy--sometimes works sometimes doesn't. *tr
