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.

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.

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....

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
