| When taking off from a start the transmission doesn't engage causing the engine to rev, then it slams into gear eventually. have also noticed a decrease in power somewhat. have had it in the dealer for service 3 times and of course they say they cant find anything wrong with it. kinda crappy since the warranty just went out on the drive train about a month ago. problem only seems to be getting worse. i have read on forums of this issue on numerous vehicles that use the 4t65-hd transmission and that gm refuses to acknowledge that there is a flaw in these transmissions. | |||

| Excessive wear on my rear tires. i have been told that the suspension is faulty and that excessive repair work had to be done to remedy this. i had to call aaa on one occassion because one of my rear tires blew out because of this problem. no injuries and i was lucky that i was driving in the city when this happened. on the highway, i could have cause great damage to myself and possibly to others around me. my car burns thru oil so super fast. it burns a quart of oil approximately every 750 miles. | |||

| I was starting the car up and the engine was going in and out. i noticed that the check engine light was on and it stayed on. the stabili-trac light also came on. the panel also said that the engine was losing power. this happened 2 times within the last 8 days. i stopped the vehicle and turned it off. cranked it back up and the check engine light was still on. took it to the car dealer and they said that it was the throttle position sensor. *tr | |||

| I was going down the road and out of no where my car says service traction control, followed by service stabilitrak, followed by engine power reduced with a check engine light on. lost almost all power to the car, could barely turn the wheel and the brakes felt extremely strange. i could only go about 5mph tops down the road. luckily i was only 2 min from home. which actually took 6 min because of the reduced engine speed. right before i pulled in the driveway the motor died. the next day i went out and tried starting it. the remote start wasn't working and my check engine light was still on but it did start up with a turn of the key. i looked up codes and found that it was telling me the accelerator pedal sensor was bad. i have googled this issue and found that it is a very dangerous, common problem with the chevy impala. although that is the code it is giving me, other people have had to replace their throttle body to resolve the problem. gm should recall it before someone gets hurt. i will not be buying another gm vehicle in the future because they are too cheap to fix this common issue which could essentially cost someone their life. *tr | |||

| I was traveling on a highway near to my home, and for about a month now the vehicle has come up with an error stating reduced engine power. suddenly, the vehicle simply stalled itself, coming up with a message that stated starting disabled/service throttle. i was traveling uphill at 40mph, now with no power brakes, no power steering, and the engine completely shut off and unable to restart. luckily i was able to pull over and disconnect the battery and reconnect it to restart it. what if this had happened on a highway on or off ramp? or on a corner? or with a vehicle traveling behind me? i believe any vehicle that will just randomly turn itself off due to a part that has had hundreds of complaints that i've just read online is unsafe to be driven on america's highways. i read online that this was a prevalent problem with these vehicles, and i hope i get injured because of it so i can sue gm. | |||

| Check engine light comes on due to constant sensor failures. the first was a faulty oil sensor. the car shut down and was unable to start or run do to a service stabilitrak code. because of theboth issues we were unable to properly secure the car and its contents. the breakdown also cause us to be stranded in extremely cold weather. *tr | |||

| 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. | |||

| 2008 impala has bad gas pedal while you are driving the traction light and engine light comes on you lose a lot of the engine power until the traction light goes off this is very dangerous. i called gmc and took it to a dealer they put it on the machine first i was told it was censer in the pedal. next i was told it was the wiring harness. by the same dealer now i dont know what to do i think something dangersous should be fixed by the dealer but they say it is not covered. | |||

| 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 | |||
