| Intermittent problems with service traction control and engine power reduced. my impala is starting to rumble and jostle when these warnings appear. however, i can't figure out the reason. | |||
| 04/23/2012 | |||
| While i was driving an error message appeared on the panel engine power reduced. the car immediateley slowed down as if the engine had cut-off completely. it did not and i was able to drive to the side of the road at about 10 mph. luckily it was late at night, the few cars that were driving near me were able to change lanes before a collision occured. | |||

| I am the owner of a 2007 chevy impala, which is no longer under warranty. (last 8 of vin #79290581) i have had several problems with my vehicle for the past several years starting with the check engine light. when i was in school in virginia the light first came on and i took it to a gm dealer in virginia for a week, they said they fixed it and a week later it came back on. i brought the vehicle back and they said they fixed it again, however it once again came back on. this is extremely frustrating because it wouldn't let me accelerate over 25 mph and i needed to get home to new york. several months later i received the check engine light again and brought it to a gm dealer in new york, who supposedly fixed this problem. last week the check engine light came on again with the message reduced engine power once again and the car stopped on the highway and shut-off. this is extremely dangerous as i was stopped on a 60mph highway with cars just missing me. i have spent thousands of dollars as a college student trying to repair this issue which still has not been resolved and now has become an inconvenience, a toll on my bank account, as well as a very dangerous safety issue. i am scared to drive my car to work everyday now, which should not be the problem because the engine light and reduced power is still on. i have looked online at several message boards and everyone has said the same thing about this problem. clearly this is a manufacturing error and as a safety measure gm should really place a recall on this before someone dies or is seriously injured from this. i appreciate your immediate response to this inconvenience and safety issue. thank you, | |||

| While driving on the interstate, a message was displayed saying service traction control and reduced engine power. i was using cruise control and it shut off after the messages were display and i was unable to stay at the speed limit or accelerate quickly if needed. in another incident, i was driving and the two messages displayed and a few minutes later the engine shut off completely. the power steering was not working and the engine was not responding. the only way to get the car running again was to shut it off and wait several minutes until it would start again. | |||

| I own a 2007 impala lt 3.9 l. purchased from sunset chevrolet in sumner, wa 1/03/10. not even 3 months after buying the car, the engine oil started leaking, the transmission started leaking, the power steering started making an abnormal noise, and the car needed a brake job. (front and back). took car to dealer (burien chevrolet in burien, wa). was told that the needed repairs were not covered by warranty. we declined repairs as we could not afford out of pocket cost. contacted general motors. was told that at the time the vehicle was taken to the dealer, that relevant components were indeed covered by the warranty. gm was unsure of why dealer had told us they were not covered by warranty. but that the warranty was presently expired, and even though it wasn't when we took car to dealer, there is nothing they can do now that the warranty is expired. also, the tech at burien chevrolet said that he could see no signs of the symptoms that we described were wrong with the transmission, even though there was a service bulletin issued by gm on 10/15/09 (06-07-30-023c) which describes the symptoms exactly as we told the dealer. it also contains information neede to repair the problem. now the transmission is on the verge of breaking down and the engine is leaking oil more than ever. | |||

| My vehicle has the 3.9 l ltz package. it uses 2 to 3 quarts of oil per oil change. i am currently working with the dealership to monitor my oil consumption every 1,000 miles. so far we have used 1/2 quart in 2,000 miles. the dealership does not seemed concerned but frankly my car should not be using any oil. gm should do something. we have a 10 year/100,000 mile warranty. i hope gm doesn't try to squeak out of fixing this issue. | |||

| Shortly after purchasing the vehicle, electrical system and on-board computer issues started occurring: tire monitor system (tpms) in-op. warnings randomly appearing in dash: check tire monitor system. check left/right rear tire pressure. tpms did not warn of a flat tire even though a significant amount of air was lost. increasing no. of issues with electrical system: keyless entry fails. check airbag warning appears. check a/c warning in dash. ambient temperature gauge erratic. compass showing n (or ne/nw but always incorrect heading). cruise control will not resume at times or set incorrect speed (a few m/h higher or lower). speed has increased on its own. once, i noticed the speed at over 80m/h when i had set the cruise control at 70. dash displaying warnings quickly and yellow warning lights flash briefly, which is extremely distracting and warnings cannot be read. tpms light comes on routinely after driving for 1-3 hours. warnings may flash at any time. took the vehicle in six times at the request of gm. some parts were replaced but electrical issues keep increasing and original issues cannot be fixed. keyless entry working for now, after components were replaced twice. e-brake did not work when the vehicle was purchased. though promised by delivery, car had to be taken in five times for e-brake to work modestly. i am not in possession of any old parts as repairs were performed under warranty. *tr | |||

| We bought our 2007 chevrolet impala 3lt new in february 2007. the car just turned over 50,000 miles. at 38,000, we noticed the passenger seat heating element quit working. chevy dealer estimates the cost of repairs at about $200. at 48,000 the shifter release switch stopped working, so the shifter could not be moved from the park position. chevy dealer said a wire broke in the center console and repairs were $137. from about 45,000 miles to present, the transmission occasionally slips when accelerating from a stop at an intersection. the engine revs for about a second or two before the transmission engages. the chevy dealer has had the car in twice for this problem, the second time for more than a week, and we're told it doesn't happen in the shop. the slip happens about once every two days that we notice. now, at 50,100 miles, the exhaust has gotten louder and a repair shop said there's a crack on the top of the left muffler. the chevy dealer says it's not in warranty, and the job will cost $1,152. an independant repair shop says the muffler can be replaced for $160. | |||
