The turn signals stopped working. After panicking and turning on hazard lights, then again trying the turn signals, did they decide to begin working again. Now the turn signals randomly decide to stop working, and must use the hazard trick again to get them working. Almost caused numerous accidents, and caused a traffic ticket. Can not figure out the problem as to why they do this, but read up on many different sites that many different people experiencing the same difficulties. Very dangerous for people with children.

While driving on a state highway in Alabama, all of the warning lights in my instrument cluster became illuminated. I determined that my engine had shut down. After shifting into neutral, I restarted the engine while the vehicle was still in motion. After I arrived at home, I decided to try and determine why the engine shut down. I was able to determine that while driving, my driver's seat was positioned so that my knees were close to the ignition switch. My knee bumped the ignition switch, causing the engine to shut down. Further investigation revealed that when I start the engine, if I suddenly release the ignition key (switch), the ignition switch stops just short of the off position. A slight bump or jar causes the ignition switch to move to the off position. I now drive with my driver's seat farther away from dash to ensure I do not accidentally shut down the engine.

This is a description of what happened on various long distance trips. It occured about six times since purchase and the current mileage is 71,400 over 9.5 yrs. We were driving down the highway at about 65 mph. Once in Kansas, Oklahoma, Texas, etc. The total electrical system went out. Immediately I felt the loss of power. I looked at the speedometer and saw it drop. I saw an engine red light come on. The total duration of outage was about 1.5 seconds. Upon resumption of electrical power, nothing further happened. We never lost control of the car. Over the years I checked for recall notices and checked with local dealerships. Nothing until in June 2012. From 2010-12 I had trouble starting the car when I turned the ignition on. Nothing happened. I would wait five minutes or several hours and then it would start. That happen monthly for two years. I took the car to a dealership and they repaired/replaced the ignition part at the cost of about $600. No problem since. I still have the original key from GM with the wide hole. My point here is that I could have been an accident victim from these incidents. I had to pay to get it fixed.

Speedometer changed twice by another Chevy dealer, transmission slipping, all lights went off while driving at night, cruise control went off by itself. Called GM customer service and about the lights and cruise control, answer was to have it checked, also had the transmission checked by three dealers, only one said yes it was slipping (transmission had been slipping since I got the car). No paperwork due to cost to have it checked by two dealers. One dealer (where I got the car) no longer in business but had the paperwork for the transmission complaint. But they too said they could not duplicate the problems and because of this they refused to work on the car.

When I tried to turn the ignition key nothing would happen this happened 3 separate occasions. After sitting for several minutes it would start this also happened to my brothers 2004 Impala. Took it to my mechanic and he fixed it with a new ignition switch have had no trouble since then. The part cost $195.95 and the labor was $100. We took our cars to 2 different mechanics and was charged the same price with the same problem.

My mechanic has been doing a lot of work on this car for the past month trying to figure out why my car completely powers off if I am driving on the road. After taking the diagnostic test again for the 3rd time it says we need two 02 sensors replaced and a new mass airflow sensor. Once we turned the key into the ignition the car began to smoke and burst into flames we pulled the keys out of the ignition and the fire department arrived and tried to put the fire out but gas leaked out and made a huge fire. The car tried to start up and we did not have the keys in the car the fire department had to cut my car battery out because it would not go out. Fortunately my fiance' and I made it out of the car alive. With all of the money I have been putting into this car to have it fixed and it catches on fire this makes me not want to ever purchase another Chevy car in my life and I am only 22 years old.

Engine hesitates, stalls, and shifts hard. Had to replace ignition switch and lock cylinder, heat sensor, fuel cap, reprogram antitheft, water pump, always getting bubbles in tires, gauges dnt work, puddle on pass side, heater core, 2 sets of warped rotors, traction control(ABS) keeps going off, found wires under hood chaffed( by rubbing on belt I believe)which caused no start. New problems are lights on dash and head lights will turn off at night while driving, I have a coolant leak which I think its due to blown gasket, and tonight I am driving in fog and my front window fogs up in 2 seconds. I wiped w hand and realized I was heading towards a person walkn. Way to dangerous!!!!! I have had car for only 2 yrs. I am divorced w 3 kids and 1 special needs child w lots of appts. I need a reliable car, cant afford new car or a shop to fix car. I have had to become a mechanic cause of this car and I have no time for that, thank god for internet, I wnt take kids in car after dark, it unreliable and thats sad. Please look into issues.

Have had a instrument panel cluster I have dealt with for along time why" the car will not start at times due to the malfunctioning security system, wait ten minutes and hope it starts, come on american made G.M. stand up to your ownings. Now fuel pressure regulator is leaking, have heard of numerous after market recalls not G.M. related parts once again own up to your product, especially when it concerns life and death of people especially children, for what money? profit" somebody with some power over these issues do something please.

As I am driving my car today in a 25 mph zone, I realize that my speedometer displays the speed of 105. After reading through several forums today I am shocked at the number of people who have the same problem on a 2004 Impala. My car has 40,000 miles on it and is in excellent condition. I can't believe that now I have to pay around $600 to have something fixed that clearly should be a recall. Are you kidding me" how many complaints/problems with the same parts justifies a recall" come on GM, get your act together!!!

(1) heating system failed. No heat, coolant was ok. Fan was running. Dealer examined. Three actuators in the electronics are failed and have to replace at a cost of over $550 (2) temperature gauge stopped moving. Dealer examined. Estimated cost of $~400.00 to replace ipc unit. There is one of the recalled ipc units for GM autos made between 2003-2007; but Impala was not included in the recall list. I don't know why? same electronics failed in one unit must be recalled from all the units.. these defects could increase heat in the engine block and could increase fuel consumption, failure of the engine and possibly cause fire, contacted GM but they were not cooperative and denied any claims.

The heater completely stopped working but was finally able to get the passenger side to work (it has dual temp. Controls). The turn signals work just when they want to and the windshield wipers do the same. They just stop working with no warning what so ever. Have taken it to several different places to have it looked at but nobody can determine the cause of these problems. However, upon the research I've done since these problems began I've found I'm not the only one experiencing these same issues yet there has been no kind of recalls to fix it.

We are the original owners of this automobile and, until this date, we have had no significant problems. On the above date, the tachometer and speedometer ceased to work properly. The tachometer went to zero but the speedometer went up and down sporadically. The entire rest of our vacation, over a two week period, both would cease working until auto was turned off and restarted after sitting overnight. We took the car to our dealership and, after scanning on their machine, was informed the instrument cluster needed repair or total replacement and was not covered by any warranty and the almost $500 cost would be our responsibility. We feel this is a safety issue, no matter the age of the car or the mileage, and should be at least partially paid for by General Motors. We then filed a complaint with General Motors corporation and have been advised they will do nothing to assist us with the cost. We cannot imagine what the reaction would be if an elderly person or an inexperienced driver were driving on the freeway and their speedometer shot up to 90-100 mph what their reaction would be. It is difficult to believe this would not be classified as a safety issue. Any assistance we receive in addressing this problem will be greatly appreciated.

While driving on a rural and curvy road, my lights when out when I switched from my high beams to my low beams. I could not see for a few seconds and luckily the high beams came on when I used the multifunction switch to engage them. I am lucky that no one was coming because I was unable to see where I was going. The multifunction switch did not "click" like it typically does when I switch from high beams to low beams. Luckily no one was injured when I was driving but if this happens in the future to someone else there could be tragic results.

We were driving our 2004 Chevrolet Impala this evening and have been having issues for the past month with the headlights. The dim lights would not work at all, only the brights worked. This evening, we smelled something burning and suddenly the multifunction switch was smoking and on fire. We shut off the car and waved the fire out, luckily we got out safe. We now have no headlights and had to have the vehicle towed. I have seen that this is a problem with many Impala and Chevrolet needs to take action. Someone could be injured in an accident due to their lights failing or get injured because their car starts on fire. It's a lawsuit waiting to happen.

  • 127,000 miles
On two separate occasions after dark my lights shut off. This caused a panic as I was in city traffic and could not see. My lights were on the dim mode. I discovered I could make them come back on if I used the multifunction lever to change to bright lights. I'd then switch back to dim and the lights would work for 60-120 seconds and then go out. Once again I would go through the whole process with the same result. After my second night of this happening I decided to check their inner net. I had noticed there were 26 complaints relating to the 2004 multifunction lever. I had a car load of people the first night and by the grace of god I did not hit another car. The multifunction selector lever needs to be recalled on 2004 Impala before someone is killed or seriously hurt. If nothing else I think General Motors should replace the part when reported malfunctioning at their cost.
