| While driving at highway speeds, the check engine light came on, then the service tracton control devices came on and immediately afterwards, there was a reduction in engine power and the car slowed considerably. the vehicle was taken to a dealership and was diagnosed with a failed throttle body. the throttle body was replaced and there has been no problems since. the failrue was at 51757 miles and was not covered under warranty resulting in a $400 bill that the manufacturer would not cover. | |||

| Our company owns a 2008 chevy impala that will shut off for no reason. sometimes, after the driver puts the car into 'drive' or 'reverse' from park the engine rpms surge, the radio gets louder and the car shuts off. it has surged and then died while going down the road at 50+ miles per hour. it has died while in drive but stopped a stop light/sign. the driver has to put the car back into park and the car starts. this has happened numerous times and the local dealership has not been able to fix it. it is a serious hazard. *tr | |||

| When accelerating or decelerating, the vehicle will stall. this happens 1-2 times a week. the consequences are that i am left in the middle of traffic with a suddenly inoperative vehicle. i have had a stall out while making a left turn at a traffic signal. i have had a stall out while merging onto a freeway!! most recently i had a stall out that required immediate recovery and evasive action while making a left turn which resulted in a flat tire. i have to put the car in neutral and restart immediately to avoid a possible collision. i have been very fortunate so far. the dealership service department was unable to duplicate the problem (because it is intermittent) and there was no code showing. they told me there is nothing they can do to assist me and were rude and discourteous and implied that there really wasn't a problem with the vehicle that i was just trying to get a free replacement tire. the dealership is sundance chevrolet in grand ledge mi. *tr | |||

| I was driving through a low area in the street that had a puddle of water to drive through. i was going to turn right and the steering wheel would not turn and then all at once it did turn. i did not have any more water to run through until about a month later in a hard rain and it did it again. this was also when i wanted to make a right turn. this all happened in lakeland fl. i contacted bill heard chevrolet in plant city fl and made an appointment. they checked it out and said they could not make it do that but they ordered parts ( a new belt) and installed a few days later. another rain storm and it did the same thing only this time the instrument panel lights all come on for about a 1/2 minute. i reported this to the dealer and they said bring it back in a they would check out and replace the tensioner. i was driving back to michigan and i was at the georgia and tennessee state line in a rainstorm and it locked up again. i contacted cliff anschuetz in alpena mi and made an appointment with them. they checked it out, put water on the belt but said they could not make it happen. another service rep said he would take a look at it and put on a new belt and tensioner and they did. the belt always squeals when you first start up in the morning. it still does that and i have no doubt the power steering will lock up when it rains. first incident date was sometime in march and to date. this is a very dangerous problem. *tr | |||

| The vehicle made a loud screeching noise. i can't remember if i touched anything,but the vehicle stalled while in motion. i put the car in park, and was able to restart with no problems. i then drove slowly and turned on the air; when i changed the flow of the air to flow from within the car, it made the screeching noise and stalled again. restarted the car, turned on the air and it stalled again. i took it to the chevrolet dealership and they said that the ac compressor had failed and was tearing up the engine belt, which would also have to be replaced. with parts and labor, i was quoted $1200. | |||

| I own a 2008 with less than 50,000 miles on it and the check engine light came on. i had it diagnosed and was told it is the secondary air injection system (diagnostic trouble code p2444) which caused the vehicle to fail the emissions test. the dealership refuses to repair it and states the warranty is only valid for 3 years or 30,000 miles. i cannot get the vehicle inspected until the problem is fixed and the check engine light goes off. i am very disappointed that a car only 2 years old can have such a major problem in such a short amount of time. the repairs will cost $1600 to $2000 because it is an internal problem with the engine. i tried to get the code reset only to have the check engine light come back on. *tr | |||

| My vehicle i purchases fro the dealer was supposedly in excellent shape. not until i moved to los angeles, ca. i realized that the engine was not performing correctly. the engine is to drop down from a 8cycl to a 6cycl when it is in overdrive (60+mph). (this is called 'active fuel management system.) my engine would not due that. i took it to several dealers but they refused to fix the problem. dealer said it wasn't their fault. we bought this car from an auction. i feel their was something wrong with the car. dealer inspection checklist was dated 3/26/2008. the car was a rental vehicle prior to me purchasing it as a used vehicle. the odometer reading was 12410 on 5/17/2008. i feel their was a problem with the engine safety. *tr | |||
