A traction control light comes on says it is reducing speed and the car will loose power and just die. This is so dangerous it has happened three times on the freeway with my kids in the. I received a special notice recall but when I took it in they said that since I was over the mileage they could not do the repair. The key is also stuck in the ignition and will not come out draining the batter, aaa has come out twice to switch the battery out for me. There is alwas a clicking sound coming from the dashboard.

Car is currently at 134K miles and just gave me a "reduced power engine", "check traction control", and a check engine light. I googled around and came across a lot of Chevy Impala around the same year (07-10) are having the same problem. It seems to be something with the "accelerator pedal positioner pedal sensor. Also reading into it, it claims that this problem can cause the car to suddenly stop from 60mph all the way down to 20 or zero. This is extremely dangerous and needs to be looked into before someone is hurt or killed.

I was on the interstate, going the speed limit. I had the cruise control on when the car alerted me that the engine power reduced and service traction control. I continued to drive as these messages have appeared on my car before. I traveled another 40 miles along the interstate and was about a mile from my exit. I was passing an over-sized tractor trailer going up hill when the car displayed starting disabled throttle service and the car shut off. I was in the left lane and had to initiate my emergency lights and wait for the tractor trailer to pass me so I could move the car over to the right shoulder. As the car was completely shutoff and was just coasting, I had to fight the steering wheel to control the car. I feel like had my situation was just a little different, the car could have came to a complete stop in the middle of the interstate with cars traveling 70+ mph and possibly caused a crash. I've already replaced the throttle position sensor and that remedied the situation for a couple months. This a highly dangerous occurrence that I know is common with the Impala's as I've heard it happening to several other people owning Impala's.

This problem started 2 years ago. My car would give me a warning "service traction control. Engine power reduced." Then the car would shut off. I took the car to a local mechanic where the fixed a sensor. That was around a year ago. I travel a lot for my job and today I arrived in portland Oregon had pulled off the interstate to get fuel, and once I pulled out to the extremely busy intersection my car did this again! I was stopped at a stop light and once it turned green boom car died due to traction control. So now I'm in the middle of a very busy road with traffic going around 45 mph almost rear ending me. I took the key out of the ignition for about 45 seconds and tred starting it which worked. Foolishly I thought I could at least make it to this parking lot right across the street when I went about 500 feet it did it again, in an even worse spot. I took the key out of the ignition again for 45 seconds started the car and got into the parking lot which was now 50 feet from me. I searched online for what could be causing this and that's where I found at least 50 other people having the same issue and trying to get GM to help. I will not be able to do my job if I can not get from place to place safely. This is a major safety issue that has the potential to kill people.

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.

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.

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!

Impala 6-cyl

  • 123,000 miles
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: 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.

Impala 6-cyl

  • 58,970 miles
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 Impala. 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
