Impala 6-cyl

  • 140,000 miles


Please help. I have a 2004 Chevy Impala. It has the GM passlock. The security light comes on the message board and sometimes the car will not start. The car has left me stranded about 25 times. I'm afraid one day it will be an emergency and my car is going to leave me stranded. This is a very common among Impala and other GM vehicles. This should be a recall asap. Thank you!

I was driving my 2004 Impala when I hit a pot hole. I tried to turn and hit the brakes and nothing worked. I slammed on my emergency brake and after a while I realized the car had shut off completely. A month later my boyfriend had the same experience driving it.

Impala 6-cyl

  • 130,000 miles
After listening to a radio report on npr describing the problem with GM ignition switch recalls I decided to test my own car for related problems. As I pulled into my driveway I tapped on the key while it was in the ignition and the key switched from on to acc mode. This resulted in my car engine shutting off, power steering loss, assisted brake malfunction, battery warning light, and the airbag light came on. All of these problems happened exactly as the radio report said they would with a faulty ignition switch. Over the last 3 years my brother in-law and I have been having various problems with our ignitions and now I believe all these problems may be caused by the defect which GM has recently reported. I have contacted the GM recall hotline and reported my car model and VIN. They informed me that there is nothing they can do since they have not received enough reports linked to the Impala. I would appreciate the recall list being expanded to include the Impala if possible. At least the years of 2003 and 2004.

My vehicle recently started having issues with overheating. As soon as it would warm up the gauge would go the whole way past the hottest possible temp on the dash. My hot coolant temp light would come on and then I would have to pull over and turn the car off to let it cool. I took it to a mechanic who said that I would have to replace the head gaskets and intake gaskets. He researched it and said that he found that Impala from 20003-2007 had problems with the engines because of an additive that was put in the engine. I paid him over 1000 dollars to fix the issue because before I took it to him I took it to a different mechanic who said it was the radiator so I got that fixed which cost me close to 500 dollars. So even after I got both of these problems fixed my car still overheats.

Engine stops running are random times. Won't restart for about 20 minutes. Very unsafe condition. Dealer says they cannot replicate the occurrence, but wouldn't come check out the vehicle when it stalled 1 mile from their dealership.

I noticed when I get to 30 mph I noticed a kick in my transmission, after that it's smooth sailing until take off again. I spoke with a several mechanic about the issue and was told that my transmission solenoid was going out. They told me the Chevrolet Impala were famous for that. So I been doing research on this situation and found out that every person I spoke with have the same situation going on. I also have a friend that has an 2005 Impala as well with the same problem. We have started a group for this. Will you please look into this situation. It will be appreciated.... in the meantime we are starting a petition.

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.

Was driving down the highway and car started to slow down. No temperature light came on but car started to smoke a little underneath hood. Stopped car at an empty lot, and had it towed to a garage. They said my engine had overheated and needed a new head gasket. It had previously had a head gasket put on it about a year ago, so this would have been the second one. Mechanic advised me not to have a second head gasket job but instead advised me to get another engine for the car.

Impala 6-cyl

  • 98,000 miles
Chevy Impala 2004 ls- the vehicle is stopping completely while driving or sitting at intersection. There is no warning, no message, it just dies. The steering goes when this happens so I cannot even get off the road. Then there are times that the car will not start at all and I have been stranded. Eventually after about 20 minutes the car will start- I have already replaced the starter but the problem still exists. I have had the car checked out at 2 different shops (Firestone) and they cannot find the problem. There are no codes coming up. They are completely perplexed. Chevy states their mechanics are better. Also the cluster panel is gone and Chevy is aware of the problem but they only recalled certain models and did not include the Impala. I have 2 estimates regarding fixing this problem but the quotes are $500. I do not feel that I should have to pay for this when Chevy knew they had this problem with cluster panels and omitted the Impala in their recall. So, to recap: The car dies in traffic (almost hit twice), I do not know how much gas I have, how fast I am going, or if the car is overheating. In dealing with Chevy I was told to take the car to a Chevy dealership. They gave me a place that is 2 1/2 hours house away from my home. I was also told that I would have the honor of paying for the diagnostics. In researching this problem, I have pulled up several complaints from other Chevy Impala 2004 owners that are experiencing the same multiple problems. I also noticed that most of the complaints are stating that the same issues occurred at approx. The same mileage as mine. I have discussed this with Chevy customer service and basically that was ignored. This car is hazardous to drive and potentially will cause bodily harm. Dealing with Chevy is pointless. All they can think of is how much money their defects will bring in.

Impala 6-cyl

  • 120,135 miles
First at buying my Chevy Impala it had 115,000mi on it already but desperately needed a car being a single mother. After having the car a little over a month the fuel injectors blew where my car would no longer start. Got it fixed. Next I had to keep putting power steering fluid in (once every week) went to a mechanic, he said my power steering is going to eventually go.. next 2 months after that my car caught on fire through the lighter. Electrical. Called the fire dept. They had to cut the wires and pull the fuse. 2 months after that, my transmission blew. Just like that. I was driving on the high way and approached an accident. After coming to a complete stop tried to pick speed back up and it wouldn't go anymore than 15 mph. I pulled off to a rest area, sat there for 30mins. Reversed out of the parking lot, put it in drive, it wouldn't budge... not to mention a month after buying the car. The turn signals, , brake lights, cruise control, flashers all worked when they wanted too and not when I needed it too. Came close to a few people running in the back of me due to back lights not working.. and my temp, gauge, speedometer and gas gauge do not work. Id be in park with a full tank of gas, it says im going 80mph and gas is empty.. hate this car with a passion.. very dangerous car...would never recommend this car to anyone....

Impala 6-cyl

  • 97,000 miles
Vehicle stalled out / stopped while traveling down the road. It has done it twice now. This car is fully equipped with cruise control and traction control. After the first time (three days ago) we took it to a dealer and they could not find any code (s) and or replicate it. It just happened again today. Both times the car started right up. This could be a disaster at high speeds on an interstate. Thank you. The consumer stated the vehicle stalled for a third time. The dealer ran it for codes and immediately, it came back as a problem with the mass air sensor. It was replaced and so far, there have been no more problems. Updated IVOQ 08/01/12
