I was sent a recall for my vehicle. I think it is terrible that you have not found a way to fix this problem since it has been known about since 2003 and you kept on manufacturing this product. Public safety is of no concern to you until someone gets hurt or killed and you are forced to respond and even then you do not fix the problem. All people who own this vehicle should be reimbursed as now there is no way now to sell the vehicle privately or as a trade because of this defect. (there was no accident or incident except for the fact that I bought this defective car, and you knew about the defect and let no one know).

First, when I slow down to turn a corner, I take my foot off the gas. After the turn, when I press the gas I have no power. It doesn't die, it just won't go anywhere for about 15-20 seconds, no power. That doesn't sound like a long time unless you are sitting in the middle of a busy intersection. I have to come to a complete stop for about 20-30 seconds, then take off. Sometimes it goes, but feels like it jerks into gear. That's ok at stop signs but stop lights that turn green as I approach can be dangerous. Also, if I turn a corner onto another street, it hesitates. And sometimes I have almost been hit from behind. People expect you to turn and proceed. When you just stop, they may not. I also noticed one day, when I just coast on a level road, my car sometimes accelerates for quite a while, instead of slowing down immediately. I once took my foot off the gas at 45 mph and coasted on flat road for 2.5 miles. The latest related problem is.. spring 2013, twice, I turned a corner and it just died. I had to pull over to the side of the road to get out of traffic. After a few minutes, it cranked back up. Thankfully, I was on a city street and not a four lane road. I also have problems with parking. I put my foot on the brakes and pull into parking spot. When I put it in park, it lunges forward. Or if I stop in traffic, sometimes it lunges after it stops. I have to make sure that I leave plenty of room in front for this problem. I think it has something to do with the computer allowing the gas to flow or stop. I had the transmission rebuilt and it still does it.

I own a 2007 Chevrolet Impala ls. For some reason, there is a clunk/knock in when I steer to the right. At times it has a tendency to lock up. Also, there is a strong vibration that occurs when I am doing 35 mph or faster. I do not feel safe.

  • 5,500 miles
I purchased the vehicle with 704 miles on it in February 2008. In may of 2008, the traction light came on and the traction control and ABS were "disabled". I took the vehicle in to the dealer where I purchased it, and they told me I had water in the fuel. As I was leaving the dealership, the transmission stopped shifting, and the car went into "limp" mode. I left the car to have the transmission control module replaced. I received the car back 5 days later and the light came on again, and the ABS and traction control where disabled. I took the car to another dealership in the hopes that they could find the trouble. After 14 days in service, they determined that rust has clogged the fuel system of the vehicle. The vehicle currently has 9,800 miles on it. The car is now "undriveable". they have yet to address the root cause of the safety issue that was the catalyst for the service visit.

  • 10,800 miles
The contact owns a 2007 Chevrolet Impala. While driving up a slight incline or when making a turn, the vehicle shuts off. The failure only occurs when the fuel gauge indicates that there is 70-80 miles left in the tank. The contact must turn the engine off and restart the vehicle to allow the failure to correct itself. The dealer stated that the failure was the result of how the fuel system tank was designed. Due to its flat bottom, air enters the system and causes the vehicle to stall and shut off. The dealer stated that nothing could be done to remedy the failure. They further advised her to keep the fuel tank over a quarter full for the failure not to occur. The speed was unknown. The current mileage was 10,860 and failure mileage was 10,800.
