Tl* the contact owns a 2000 chevrolet impala. The contact stated that there was a progressing failure in which the pressure was low on the reader and the vehicle hesitated numerous times before it stalled without warning. The contact had to make several attempts to get the vehicle to restart. The vehicle was taken to a repair shop mechanic who replaced the ignition switch and the oil pressure gauge, but the failure recurred. The vehicle continued to stall. The VIN was included in the federal safety agency campaign number: 14v400000 (electrical system), but the contact did not receive a notification. While at a stop light and upon acceleration, the rpms and pressure went low, the vehicle stalled, and an engine fire erupted. The contact was able to exit the vehicle. The fire department extinguished the flames. A fire report was filed. The vehicle was towed to the contact's residence and then towed to a salvage yard. The vehicle was destroyed. The contact received notification of the federal safety agency campaign number: 15v701000 (engine and engine cooling) and was unable to receive the recall repair due to the failure happening before being notified of the recall. The approximate failure mileage was 120,000. Parts distribution disconnect. Vin tool confirms parts not available.

Dt*: the contact stated the check engine light illuminated intermittently. While accelerating from a stop, the transmission dropped to the lowest gear without warning, and hesitated before engaging to the next gear. The vehicle was taken to a service dealer, who was unable to determine the cause of the problem. Also, the fuel gauge displayed an incorrect reading. Finally, while driving 30 MPH, there was a rattling noise in rear wheels. The last two problems were inspected by a dealer.

My 2000 chevy impala hesitates when it starts, it seems to get worst when it is about 90 degrees outside. Dealer replaced a couple of parts, but now the said they can't do anything else about it. I said that the should replace the engine for a new one. I am just a consumer.

I look on here and see a number of things going on with my car. Rolling on hills, driver window switch,constant burning of spark plug wires, my keyless entry never worked, I've had roters turned and replaced numerous of times. But the 2 things that are bothering me are 2 parts that have been recalled for 2000 impalas don't match my VIN # for the recall. I don't understand if I'm haveing the same problems as they are. 1 is the rack n penion piece which is causeing the popin and stuff under the front end that most of the complaints you have are and the second is the intake manafold gaskets. Are they just replaceing these 2 items on police issued and taxis ? And also the hesitation &shut off that everyone is talking about. I had the same problem it was a wireing problem that was laying on my exuast. I have had to fix normal wear and tear and don't mind. But a single mother of 4 and gm who do you think can afford to fix things more. And I feal that the should fix there faulty material as I have fixed my wear and tear. If that rack n penion breaks and I losse control of stearing in my car my family is aware of the problem and I promise it would of been alot cheaper to go ahead and fix it for everyone. It's sad that we have got to go to limits of putting ads in paper, calling people, and almost a act of congress to get any kind of help. How many cars have lost control of stearing? (rack n penion) what happens when I expect my keyless entry to work because I'm in danger and counted on it? Or maybe when one of those wires that's burnig up catches my car on fire. Out of 600 complaints the three most complained about items rack in penion, wireing, and the car rolling bakwards were you keep 1 foot on the gas and 1 on the break. If that's not enough I don't know what is these are safety issues. I will gladley let someone drive mine to see.

When pulling out into traffic the car hesitates. This usually happens on the second or third start. Have brought it back to the dealer. They rerouted some wires on 10/9/01, it happened again 10/12/01. Have brought the car back two times since. They cannot reproduce the problem. I am afraid to put my kids in this car. I called chevy and was given the run around. Finally they admitted that this was a characteristic of the car and that they were working on a fix. And then told me that they could not fix the problem until they could see it happen for themselves. I don't know what to do, but I can tell you I don't trust the car and do not want to put my kids in it.

After car had been driven several miles, then shut off for 45 to 60 minutes, upon starting and trying to get back on highway the engine would hesitate at about 5 MPH car speed, for 2 or 3 seconds, with the accelerator pedal pushed trying to speed up, the engine would finally catch up to the gas pedal setting and spin the tires. This happened 4 times one day. Four visits to the dealer didn't help. Since one chevy dealer replaced a control on the transmission, the engine has hesitated going around a corner at 20 MPH. Three other times it hesitated when I tried to leave ny driveway.

Vehicle has enough gas to accelerate. Once out in the open it hesitates 5-8 seconds before moving at its speed. Dealer put a black box to register problem, but nothing showed up. This is an ongoing problem that consumer is scared to keep going through. Dealer and manufacturer still haven't found a remedy. Please add VIN#.

Our impala has had a problem where it hesitates and stumbles when you try and accelerate since it was new. The dealer has not been able to identify the cause. This a hazard! I think we should get our money back but they keep giving us the run around "you bought and now it's yours". I think that stinks! I see other complaints concerning this problem on your web site, can't you guys contact gm and demand they do something about this?
