Loud clicking noise. I think it's somethings to deal with the air conditioner when the button is on the blue area. Actuator? The clicking sound would come and go. When I press the key button on my keychain. Pop the trank and sometimes it just goes off through the the day when the car is off and park.
2009 Chevrolet Impala driver assistance complaints
Page 3 of 6: complaints 41 to 70 of 147, newest first, as owners wrote them.
Indicator lights for reduced power, service engine and traction control lights come on at anytime and go off. Experience a little lack of power. I will do it any time and any condition. It is random. From what I have read I am worried if the car will leave us stranded.
While driving on the highway the vehicle would display engine reduce power message then the engine would reduce power and stop. I took the car to the dealer on 12-21-15 with 118755 miles they said no codes. I stated the battery died they said bring it back k if it does it again. I took the car back on 3-17-16 123236 miles the code was in the system but they said it is not covered now over the miles. I called gm on 3-17-16 they said they would look into it and call me back. Gm called back and said they can't help me( case # 8-1882923571). I asked when the notice went out and he said he didn't know. I think this known safety issue should be covered. The dealership was chuck nicholson gmc dover ohio 330‑343‑7781.
While traveling home at about 55 MPH car in front of me slammed on their brakes causing me to do the same - then traction control light came on - check engine light came on and reduced engine power came on in the display window - felt like all four wheel jumping up and down when trying to gain any speed weird sound coming from engine (normally quiet).
Service traction control light on & check engine light on too. Looks like same problem as ten million other people (good luck for us all - time to go back to bmw). Have to stock up on sensors I guess
I bought my 2009 chevrolet impala used in april 2015, and since then I have had the warning service traction control, followed by engine power reduced pop up about a dozen times, with varying lengths between incidents, but not until yesterday did the car respond in any way. Yesterday I was accelerating up an interstate entrance ramp when the service traction control message popped up, then engine power reduced, and I paid little attention until quickly after the second message I realized I had no power, I had the accelerator to the floor and the car wasn't responding, the engine had shut down. So I turned on my hazard flashers and tried to pull over to the berm, but had to fight the dead steering wheel to do so, the power steering had stopped working when the engine shut down. The car wouldn't immediately restart once I had come to a stop, but after letting it sit for a few minutes, it started and I had no further issues getting home. I have read about this problem with this model vehicle here on this website, but this is the first time the engine has shut down on me after the two warning messages, and I was very lucky that there was no traffic in the lane I was trying to merge into when it did happen.
I was driving on the highway when the service traction control came up on the dash along with the traction control light, with in seconds of this happening the car read reduced engine power. The car immediately lost power and slowed down to a maximum of 25 MPH. This sudden loss of power caused the cars behind me to nearly miss rear-ending me. I had to drive in this crippled mode 10 miles to reach the closest exit. It is due to a faulty throttle position sensor. This seems to be a very common problem with these vehicles and can cause a sudden loss of power.
Traveling on highway at 70 MPH. Service traction, reduced engine power, service engine lights came on, car was shaking, everything was shutting down. Fortunately it was not rush hour and I was able to pull off road. I was on a toll road that aaa can not respond. I waited about 20 minutes and started the car and everything was fine. Took car to our mechanic, there was a service bulletin, to replace throttle body assembly. Since then, 2 letters from gm about covering cost of throttle sensor, but not assembly. Gm is not taking care of the real problem, the whole assembly needs to be replaced, not just the sensor! I've kept the part and invoice and letters from gm, they should just recall before it turns into a class action lawsuit!
My name is [xxx] and I purchased a 2009 chevy impala, with 123,000 miles on it, in august 2015 from mac churchill auto mall in bedford, texas. I have had no problems with this car since its purchase until november 29th. While en route to emory, texas, my car started displaying "engine power is reduced" and "service traction control" messages. About 99% of the way there, I suddenly got a lurch and my car slowed down, with steering and braking not working. I was able to get my car off the highway safely but had to use my emergency brake to stop my vehicle and get it turned off. I tried repeatedly for several minutes to get it going again, but it would not start. After about five minutes, the car restarted normally and has performed flawlessly since. However, I am concerned. I've had a garage pull and diagnose the problem. The error codes that were pulled are p2122 and p2138 ,regarding the accelerator pedal position sensor. I've researched this and this appears to be a common problem from what I've been able to ascertain from my research. But I'm confused as to whether this is a recall item based upon this: http://www.naioa.com/v2/modules.php?name=forums&file=viewtopic&t=49934 . I'm now trying to understand whether I can get this fixed because I'm not sure this is covered under my used car warranty and I do not feel compelled to pay for a repair that gm has been aware of but failed to notify my dealership or me as a owner, until I got a letter on 12/9/15 indicating that there may be a problem...well after I started having problems. I want gm to fix this at their expense. It is a safety hazard here in the dfw area because this could reoccur while I'm in heavy traffic and have no way to stop before someone hits me or I hit someone.

For a few years I've had problems with the accelerator pedal. The first time was roughly two years ago when the car completely locked up and shut down on the highway just before rush hour. I received an error code to check traction control and that the engine power is being reduced. The car then looses speed dropping drastically. The first time I was in the fast lane on the highway and the vehicles computer system shut down. The steering wheel locked making it very difficult to veer off to the side of the high way. Luckily no other vehicles were directly behind me, and I was able to get the car to the side of the highway accident free. I've never been so afraid and terrified in my life. I fear this issue will cause fatalities that can be prevented. I had the car serviced at a chevrolet dealership in ann arbor mi which was an expensive fix! Since I've had the accelerator pedal replaced, the vehicle has shut off two other times followed by the same warning message to service traction control and engine power being reduced. I've written in to gm and they continue to request that I pay a diagnostic fee at a dealership for them to address the cause. I cant continue to pay $200-$300 for this fix when it is a manufacturers issue. This recall has been done on other chevrolet models and I am praying for a recall on the 2009 impala. This is a major safety issue to my family and the drivers who are around me. The issue is still present and is a major concern. The vehicle speed cant exceed 40mph at times, or will instantly drop at unexpected moments. Please investigate this issue.
Vehicle shutoff and I lost steering and braking causing vehicle to crash and airbags did not deploy. The vehicle was in motion.
Tl* the contact owns a 2009 chevrolet impala. While driving approximately 55 MPH, the traction control warning light illuminated along with the warning message "engine shutting off". The engine was then shut off and could not be restarted. Approximately five minutes later, the engine was restarted and the vehicle operated as normal. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 93,683.
My car shut down on me on may 15 2015.service traction control and reduced engine power message appeared. I managed to drive the car home at slow speed.this is a safety issue. I have read reports that similar problems have appeared on other 2009 impalas. Some reports said the car shut down completely in fast moving traffic.I had my own mechanic look at the car and the part that needed to be replaced was thea.I.r. System check valve.I later received a notice from chevrolet about another problem that could cause the car to shut down unexpectedly. (app) sensor accelerator pedal position sensor.I believe a recall should be issued for these problems because of the potential for accidents on the highway.also, chevrolet did not cover the cost of the repairs to the a.I.r. Pump. Thank you
Tl* the contact owns a 2009 chevrolet impala.

My wife and I were driving down the interstate at approximately 65 MPH. A light on the dash came on saying engine power reduced. At that point my vehicle slowed down to nearly 20 MPH while I was still on the interstate in moderate traffic. I pulled off to the side of the road and turned my vehicle off to try to investigate the problem. At that point my vehicle would not start for about 10 minutes. After getting my vehicle to start I immediately drove it home. This issue could have caused a very serious accident that would have injured my wife and I, but more importantly our 7 year old daughter riding in the back seat along with any one else involved. I have been on many different forums trying to figure out the cause of the problem, and it seems there are many people with this exact problem on their chevrolet impalas.
My 2009 chevy impala had experience intermittent message "service traction control" along with "reduced engine speed" since august of 2012. It happened maybe 1-2 times per year for the last few years. The message would clear itself after the car was turned off and sat for a few minutes. On july 24th, my car experience these same messages once again. However, the message came and went multiple times and all speeds in town and on the highway. The message finally stayed and did not go away on july 25th. I scheduled service at the local dealer on thursday, july 30. They changed the accelerator pedal and thought it was an issue that gm issued a special condition on in april 2015. On the way home from the shop, the message appeared again. Thus, the car was again serviced at the local dealership on friday, july 31. By august 1, the "service traction control" light blinked on and then went off quickly. It did the same thing one time on august 2nd. Today, august 3rd, the light went off three times in a short drive and is once again stuck on. I'm very worried that the reduced engine speed will return when I am on a highway. This is a known issue by gm or they wouldn't have issued a special condition. They only will fix this up to 120,000 miles. If my engine turns off while moving at 70mph on highway, this will be huge safety concern. I'm waiting on the dealer to call me back to once again return my car for repair.

I was driving about 40mph then my car broke down speed traction sensor was on and engine light came on and it read engine power had been reduced as I kept driving it was jerking and not wanting to pick up speed I turned the car off for about 30 minutes started again traction light off but check engine light still on went to oreilly and it read a code saying pedal position sensor
Tl* the contact owns a 2009 chevrolet impala. While driving approximately 65 MPH, the vehicle stalled and the service traction control system warning light illuminated. The vehicle was taken to a dealer where it was diagnosed that unknown sensors related to the traction control needed to be replaced. The vehicle was repaired, but the failure recurred. The manufacturer was notified of the failure. The failure mileage was 70,000.
Since we have had this car we are constantly having stability tract control sensors. We have replace them once and it is showing up again. When the stability tract control goes bad then the ABS and brake assist light also comes on along with it. I would like to see a recall fix for this problem as I know I am not the only one who has had these problems with their impalas.
I was driving on the highway during rush hour traffic going approximately 65 per hour and the service traction control came on and then said that engine power was reduced. It also had the engine light come on and stayed on all the way home. I then got home safely that time and shut off the car about 20 minutes later went out and all lights had gone off and was back to normal. This has happened at least a dozen times since then. Then on 6/29/15 this happened again on the highway during rush hour traffic. However this time the car said throttle disabled and the car shut off completely in the middle of the highway and I had to try and get to the side of the road without incident. After about 10 or 15 minutes the car then started back up and the lights went out and I was able to drive again. Then later in the day I returned home and tried to leave in my car and it would not start and had no power what so ever. The key also would not come out of the ignition and I just had that recall dealt with on the key. I could have been seriously injured in this last incident. This needs to be recalled and gm needs to pay for what I am out of pocket because I now had to get a rental car to work. I have read pages upon pages of complaints just like mine, which is ridiculous that this issue has not been fixed. Does it take someone getting injured or killed for gm to do something?
Traction control light, and reduced engine power light came on. Lost power to the engine and had to stop. Turned the ignition off. Waited 10 minutes and started the car. Ran fine until I got home. This happened a few times before I took the car in. Found out it was an accelerator pedal position (app) sensor.
Tl* the contact owns a 2009 chevrolet impala. While driving at 40 MPH, traction control, engine power reduced was displayed across the message board. The contact independently replaced the accelerator pedal; however, the failure recurred. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was unknown.
I was driving on the highway and all of the sudden check engine light and traction control light come on. Warnings service traction control and reduced engine power are displayed and all but shuts my car off in the middle of the highway causing cars to slam on their brakes and swerve barely missing me. I get over to the side of the road and turn the car off. Then turn the car back on same messages and won't go no where. Do the same thing again only waiting longer and no messages but check engine light still on. I drive home. Next day no warnings or lights. Couple weeks go by does the whole warnings and lights and slows car down again but doesn't completely shut it down. I was in regular street traffic this time about 35mph. And now it's more frequent sometimes a couple times a day to once every day or two. This needs to be looked at. I'm reading about this problem on a lot of impalas causing major problems and wrecks.
Tl* the contact owns a 2009 chevrolet impala. The contact stated that the check engine and the traction control warning lights illuminated. In addition, a chime sounded. The vehicle was taken to the dealer where unknown repairs were performed. The vehicle was not repaired. The manufacturer was notified of the failures. The failure mileage was 120,000.
The traction control, stability track and ABS lights all came on. The engine power reduced light came on and engine power was lower. I had the left speed sensor replaced and the accelerator sensor replace on august 8th after the dealership had fixed this problem in april and again in june. I was told they changed sensors then also, but I am not sure of which ones at that time. I am now having the same problem for the forth time. Replacing the sensors every few months is getting expensive. Also not very safe. I contacted gm and the woman told me to take it back to the dealership to be fixed again. I have fixed the same issue three times already. They were of no help at all.
While on my way home from work on a major highway, message lit up saying engine power is reduced, service traction control, then said starting disabled and the engine shut off mid highway with no time to react. I was almost hit by several cars, tractor trailer, and buses. I had no power steering, nothing. I have 5 children who are often in the car with me and this created a mess of traffic and could have killed people. After being scared out of my mind and stuck half in a highway lane for 5 min with traffic swerving, the car started back up with no issues and I continued home. No sign of anything today, however I am reading thousands of complaints online from other chevy impala owners who state they are experiencing the same issues and it comes and goes and have tried everything to fix it and it still happens every so often sometimes more than others. Someone is going to lose a life.
While driving onto a highway when I reach 56 miles per hour my vehicle lost power and slow down the brakes locked and the electrical system went haywire. The locks started locking and unlocking while the vehicle was in motion. The lights started flickering on and off and the car started shaking rapidly and the brakes locked up. Once I started the vehicle back up and the ignition switch seemed to be stuck and the air bag light displayed on the dashboard. When I turn off the vehicle and try to remove the key the key will not come out so I have to put it into neutral and back into park a few times before it will release the key. Since this has occurred I hear a knocking sound in my glove box when the door is open and closed and sometime hours after ill hear the noise and the electric will flicker.
'service traction control' 'engine power reduced' and engine light came on. Car lost all power. I had to wait several minutes before it would start again. I was driving 65 MPH on my daily drive of 60 miles one way. Thank goodness I wasn't passing and did not have my children in the car! This has happened several times since where I have not lost all power but partial, the cruise control will quit working and the car has very little power.
