| Occasionally, when starting from a stopped position the engine will rev up and then the transmission will kick in to gear. occasionally it slips on hills also. we generally do not have to merge into high speed traffic but if the transmission slipped at that time there could be serious consequences. the dealer has been unable to fix the problem after five visits, and apparently will not do anything until they themselves experience the transmission slip. | |||

| At a stop light.feels like transmission is not in gear,engine revs 2500/3000rpm, then trans goes in gear. told by dealer if using left foot on brake at a stop, this would cause the problem. they offered no help. was told without codes there is no problem with transmission! when i got car it was leaking trans fluid.took it back to dealer,to have leak fixed. at another shop i use, while car was on lift you could see trans pan on valve body had been off. trans has for sure been worked on! as you might guess it will not do this at the dealer.i let the car with them for 1 week,for them to drive.when i got car back they put all of 3miles on it. | |||

| Reported that car would jerk (kick into gear late) when accelerating from stop to start. at 74,000 we made our first claim with local dealer. they couldn't duplicate the concern. brought car in two more time because it got worse. felt like someone was hitting me from the back. my car often kicks out of gear on a left turn. on two separate occasions, i was almost t-boned. they never found the issue until 121,000. that was when they declared that the transmission needed to be replaced. gm doesnt want to cover the repair now that the vehicle is out ofwarranty. i have researched and found way too many transmission issues with these model vehicles. gm really should investigate this concern. i advise anyone to pester gm about this concern. afterall, we are the consumers. unfortunately it's too late for me, i don't trust their products anymore. | |||

| Exiting the dartmouth street parking garage (underground) on dartmouth st. boston, ma. exit ramp is a moderate incline. as i approached the garage attendant booth to pay parking fee, i let off the accelerator letting the car coast to a stop while i retrieved the parking time/date receipt. when i located the receipt (about 5 seconds) from the center console i looked up to find the car was rolling backwards down the ramp toward a concrete wall (by this time) approximately 15 mph. note: i am a 50 year old, (male) retired police office and was trained in radar speed enforcement including certified in speed estimation and i am also evoc (emergency vehicle operator course) trained. i was able to stop the car before hitting the wall, another vehicle, or any pedestrians. i feel a tragedy could have occurred had someone been walking in the garage. the car seems to have no ability to hill hold when in drive at idle. i was shocked at how fast the auto accelerated backward. i have personally driven approximately 750,000+ miles without an at fault collision. the car seems to do this whenever on an incline and on a few other occasions had occurred in parking lots rolling (forward as well as backward) as soon as shifted out of park in the fraction of a second time that it takes to move my driving foot (right) from brake (due to park interlock) to accelerator. note: this auto is a 2007 chevrolet impala ss with 5.3l v8 engine and four speed automatic transmission. my primary concern is that impalas are generally driven by elderly drivers with slower reflexes than myself. i have further found numerous online forum discussions of this issue by owners of all engine equipped chevrolet impalas. *tr | |||

| This car has less than 100k miles and chevy dealerships refuse to diagnose the issue with the transmissions and there are multiple complaints about this issue this car is unsafe. the issue is random jerking of the transmission upon taking off in traffic, at light, or from stand still has caused: (a) my wheels to spin, (b) the car to pull into the next lane, (c) almost rear-end collision with car in front, and (d) sudden rapid acceleration in trafffic. the car i almost rear-ended was a 2007 chevy police impala the officer exited his car asked was there a problem i told him about the transmission issue and he stated yea mine does that too this car isnt a safe one this need to be addressed nationally | |||

(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. | |||

| On december 24, 2009, after parking my 30 month old 2007 chevrolet impala ltz on level ground at 6:30am in the morning and minus 13 degrees fahrenheit, i attended my morning workout for 1 hour. on return and after successfully starting the car i found the stick shift access button could not be pushed, despite following the recommended procedures, and the car was stuck in park. it was towed to the local gm dealer for $100. after six days and $150 in expenses for another car the gm dealer reported that the problem was a broken ground wire in the shift lock solenoid connector [inside the centre console where the shift lever is located]. the cost of repair was $137. my internet research shows this problem occurs often in chevrolet impalas, which suggests that the problem is in the design and manufacture of the vehicle. this problem could be life threatening if the problem occurs in a remote area at this temperature. i thought this was a power train problem since the part allows the transmission to engage, and therefore should be covered under warranty. gm claims it is not part of the power train. my complaint is that the problem could be life threatening, is a defect in design and manufacture, and that the problem is a power train problem and therefore should be covered under warranty. *tr | |||

| Letter to the administrator from reporting transmission slips intermittently in his 2007 chevrolet impala ss *tgw the consumer stated the transmission problem usually happened when starting from a standstill or while moving at a slow speed. the consumer took the vehicle to the dealer for an inspection where they checked the shift points, checked the computer for faults and installed a software update in the computer. the transmission fluid was in satisfactory condition. the dealer stated they were unable to observe any problems with the vehicle. *jb | |||

| No signs of failure until put car in park. tried to put back into drive and shift lever would not move. read owners manual and tried their recommendation, did not work. found the ground wire for the btsi had broke do to faulty wiring at factory, yet chevy will not cover the expense. repair costed $165.60. if this were to happen in cold temps, an emergency, at a train stop or anywhere like that it could be life threating since their is no override other than tearing apart console to hit the manual reset. their is also a technical bulletin on this issue, telling me it happens quite frequently. | |||

| 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. | |||

| I purchased a 2007 chevy impala lt with 52,000 on 5.27.10. the car is unsafe, makes loud road noise, the tires are wearing out funny, even tho the car was perfect when i bought it. the brand new tires are wearing out funny, i took it to 2 shops, had rotors replaced that were warped, balanced, and rotated tires, tomorrow getting it aligned again, the dealer aligned it when i purchased it less than a month ago. the tires also need balanced again even tho i got it done a week ago. i don't feel safe driving this car it has a serious defect with the car not the tires, some kind of alignment problem a gm defect, and i'm seeing alot of others same the same thing as me on the forums about the 2007 impala. the transmission slips when taking off from a light in city at low speeds, i push the gas peddle just a little bit to speed up like a car is designed to do but the rpms go up but the car does not speed up to keep up with traffic, i push the gas peddle down half way and the overdrive kicks in without expecting it and it speeds up like a rocket in 30mph traffic. the car struggles and kicks its overdrive in to just speed up in the city, something isn't right with this. im afraid to drive on the highway with the tire wear issue, the tires are being ruined and no excuse for it. im saving and filing all repairs done to my impala... i really am afraid to drive this car over 50mph, i don't think my life should be at risk because gm slapped together a car without making it safe. i don't feel safe driving the car, it doesn't handle or stir that well either, not very responsive. i'm shocked that gm put out such a vehicle, it's a mess and i don't get it? it's a factory problem gm overlooked and not willing to recall. they should considering it's unsafe. the car has other issues as well.. a warning light came up saying driver side airbag not working, it corrected itself and went away, i hope the airbags are working properly? my girlfriend sits in that seat. i want her safe. | |||

| I purchised this car in april of '08 and it has been failing since i bought it. there is a vibration while riding in the car that makes your body bounce. the dealer states they don't feel it, but i have cronic back pain from it. i have had it at the dealer several times and no fix. i took it to an alinement shop they told me that the stuts were set out from the factory so the tires don't hit the grond flat like they should. the problem causes my tires to slip out of balance constantly making the vibration worse. my windshield and dash both make craking noises now from all the vibration in the car. it makes for a very uncomfortable ride. i am on my 3rd set of tires at 28.300. the brakes don't work properly, the dealer has turned the rotors twice for warping. now they are grooved and they tell me that it's normal and i don't have the normal stoping power i should. the power stering squiels, but they can't hear it. the front end has a banging noise when going over bumps,they don't hear,but i can feel it in the floor board when it happens. the car is sluggish when excelerating,no problem found. the fuel econemy has decreased as well. while on an incline the car roles backward like a standard,it's normal i have never had a car do that without the trany being bad. when stoped at a light the trany takes a couple of seconds to reengage for take off. tps repeated problems not working poperly. the cars handling is very poor in the rain,snow,or ice. the muffler system has a leak as well. | |||

| When i am coming from a stop and beginning to accelerate at moderate rate between 5-25 miles my car jerks very hard. the feeling is sometimes to the point it feels as if i have been hit from behind by another car. the feeling is very forceful and it feels as if it begins in under the rear seats and the rear tires. it happens sometimes maybe once or twice a day and other times everytime i press the gas upon coming out of a complete stop and sometimes it does this forceful jerk/thump/shrug consecutively as i come out of the complete stop and then as i accelerate a little more. have taken it to two certified gm service centers on 3 occasions and told them the problem. and after the last visit the problem has gotten worse. i am concerned as what to do. and the problem is progressively getting worse. it happens daily and on most occasions everytime i stop. *tr | |||

| The vehicle was purchased in march 2007 and is used as a commuter car from new oxford, pa to washington, dc daily. i average 750 miles per week. last fall when the vehicle had just over 90,000 miles, i began having problems first with the cruise control dropping off speed and not resetting. this quickly advanced to a shuttering feel when accelerating and occasionally picking up speed and within 50 miles the car refused to move after a stop light. i turned it off and restarted the engine and after putting it into drive, managed to get it to a nearby former chevy dealer. they determined the transmission was totally slipping and required replacement. chevy stood by the 100k power-train warranty with a no-cost replacement and installed a new transmission, issuing a 12,000 mi warranty. today, at 111,000 miles, less than 20,000 into the new transmission, the problem returned. the first time it was on flat ground and i was simply a stalled nuisance in traffic. this time, i was going up a hill and had stopped for a light. the car began to roll back down the hill, i had difficulty braking and nearly got struck by a large truck. it would not move forward until i turned off the engine and then with a thuds and jerks i was able to move it to a safe parking spot. this time i did not have the difficulty with the cruise control but did have a bit of what i now recognize was transmission slip but i attributed to the anti-slip brakes on ice. this happened a couple of times. from the early shudders, less than 400 miles elapsed. i was fortunate both times. *tr | |||

| Transmission slips then engages hard. has progressively gotten worse. had transmission service just about a year ago, fluid has been clean and full. i was making a right hand turn and started to go but the car would barely pick up speed, the engine revved then after about 3 seconds it jerked hard and resumed acceleration. my local dealer and gm themselves flat-out lies about the issues with this car (has had all the common things, tire wear, bad rotors, motor mounts, window screeching, steering noises, remote entry, you know, typical impala) so unlikely it will go to dealer for diagnosis. they will likely say it's due to position of the moon and direction of the wind. just hope this does not cause accident before i can ditch this car or nhtsa gets on gm's case for these defect ridden cars! *tr | |||

| At random times, starting from a stop, my 2007 chevy impala ltz car will slowly engage 1st gear and then suddenly engage with a strong jerk. on several occasions this occurred when pulling out into traffic, starting at a traffic light on a wet road, and pulling up slight inclined driveway into garage. several of these times i've lost control briefly from movement of the steering wheel, due to the unexpected power of the transmission engaging and jerking. the dealer has made multiple unsuccessful attempts at repairs throughout 2008 until now. from reading all the owner discussions at edmunds.com i see this is a common problem and a safety issue for me. *tr | |||

| 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. *tr | |||

| The vehicle was turned off, in park, with the parking brake on, in the driveway at an incline. the vehicle rolled backwards down the driveway, and hit the fence which brought it to a stop. there was damage to the driver side door and driver side rear of vehicle. the car was taken to dealer, and the event explained. the dealer made repair to door at my cost. the dealer made no attempt to determine the cause. i called again to service and spoke to someone, who stated that the parking brake is not supposed to prevent the vehicle from rolling backwards. no investigation was offered. *tr | |||
