While driving and the car shuts down, when it finally starts the engine light came on, the passenger seat comes on and no one is sitting there. Ive had it checked out something about an air mass flow sensor, then the light came on about traction.

While driving down the highway, my car shut down. This was very dangerous. I pulled over on the shoulder and every light was on stating engine power reducing. I have had this same part replaced twice in 1. 5 years and there is something serious wrong with the Impala.

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.

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.

Was driving along at 55mph and the service traction system light came on followed by the reduced engine power light. Then the car just completly died. I was able to get to right shoulder and park it. I have done some research and seems that there have been several other folks with the same issue. I can't believe that this car would just shut down and have no control. I had the entire family in the car and was thankful that this didn't cause an accident. I am looking for answers and plan on taking it to the chevy dealership I purchased the car from today or tomorrow.

Failure Date: 05/10/2015

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.

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.

The security light came on and car shut off while I was driving the car at approx 30 mph. This happened several times since then while traveling at a higher rate of speed. Luckily I did not have an accident but, I am afraid to drive the car that an accident may happen. This is a very serious safety issue. I have researched the internet and came across many complaints the same as mine. How can it be that no recalls have been made on an issue so serious?.

On my display I have seen daily (service traction action) and (engine power reduced) along with (service airbag) for more than a year, did not service due to cost and it is not my fault! my car usually slows down once the engine power reduced displays causing the car to jerk due to me trying to give it more gas so as not to be hit from the back. As my grandchildren and I were headed home on the freeway my car decided to just shut off. On the display it read first. . Service traction action and then starting disabled service throttle. My car immediately lost power and I began to pray hoping I would not get hit from the back with my grandchildren sitting in the back. Once I pulled over my car would not start I sat for about a minute and tried to start again and it started. Just today 01/12/2015, with my grandchildren in the back of my car again my car decided to loose power again but this time it did something very different, it would not allow me to first reverse and then it allowed me to but soon after I could not go forward. The gas peddle acted as though the car was completely turned off but the car was running. When I attempted to press the gas peddle I pressed it all the way down to the floor, nothing happened. I ended up calling a towing service and after telling them what happened I was told my issues stemmed from a electrical system issue that chevy had recalled. This does not make any sense for so many of us to go through the same issues but nothing be done about these issues. Something needs to be done quickly!!.

My family was driving down the interstate at 70 mph, all of the sudden these messages started to appear on the message center. Engine power has been redused, something about traction control and another message that I can not remember. The car then lost all power, it shut off completely. We did make it over to the "slow" lane, but there we sat on the interstate with traffice all around us. The car would not start!!! need less to my girls and my self were terrified that we would be hit. After about 10 minutes the car did start again and we made it to our destination. The messages are not displaying now, but the engine light is still. I am taking it to the shop today. What will it take before gm does something about this??????.

While driving on the highway the "service traction control" message comes on, then, the messages "service stability trak" then "engine power is reduced". And then the car shuts down I had to quickly pull over on the side of the road. After a few minutes the car starts up and everything is fine. This happened twice since then. Every couple months the sensor lights would come on with the above message-without car shutting down. The lights come on a lot more often now-although the car does not shut down, it's the fear of the possibility. When googling this problem with the car it sounds like this is a common problem. I'm not sure why there hasn't been a recall. I'm bringing in my car tomorrow to get fixed. However, its upsetting that there seems to be a problem with the throttle position sensor, and there was a recall on a GMC truck in 2008 for this problem. This seems to be a problem regardless of year of miles of the Impala.

My family and I were traveling from newark, NJ from the July 4th holiday back home to raleigh nc on 95 south in virginia and going at a speed of 72mph approx. And the car/engine just turned off at that rate of speed with 2 children in the back seat of the vehicle. After we sat on the side of the road for about 45min the vehicle proceeded to start and we made it home to nc. The following business day after the holiday I took it to my mechanic giao auto located on capital blvd in raleigh nc and he could not determine why the vehicle shut off the way it did. So I continued to drive just with precaution. I received a letter on 8/21/2014 regarding the recall and was livid because this has happened to my family while driving on the interstate! I believe that this may happen to my family again and do not want to risk this, so I would like to know what can be done to ensure that my children have a safe vehicle.

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?.

The traction control light comes on, then you get a message saying the engine power is reduced. Then you get a message saying the car is shutting down. This has been happening every once in a while, but now it's a lot more frequent. This Saturday I was driving about 60 on a three lane highway with no shoulder/break down lane. The car shut off while I was going up a hill. Cars were flying up behind me and swerving to miss me. Normally it takes about 5 minutes and you can restart the car. This time it was almost 10 minutes. I had a panic attack sitting there. Once the car finally started I drove about 50 feet and it happened again. Luckily there was a dunkin donuts there and I coasted into the parking lot. I sat there about 20 minutes so I could catch my breath, stop crying and composed myself. When I went to the dealer about 6 months ago they said it was my gas pedal, and it was going to cost $164. However when you research this on the web, you will see most people who have the gas pedal fixed it happens again. There should really be a recall on this because someone will get into an accident and perhaps get killed.

The engine shut off after hitting a large bump in the road. The engine shut off a second time again after hitting a large bump in the road. The power steering and power brakes were both affected. The car restarted. The dealer looked at the car and couldn't duplicate the condition. The problem went away after I removed all the keys from the key-ring.

Driving to work and I got a display message that said some thing similar to "stabilitrack repair, engine power reduced" and then the car shut down. No power steering, nothing. I was finally able to stop, but I wasn't able to get off the road and it caused a potentially dangerous situation. I've read online this is a common issue with Impala's and something that is a design flaw, as the shutting down of the car is not needed. Had I been in traffic, a large car pile up would have resulted.

This vehicle has a push button engine shut off button. I went to a shopping mall and forgot to shut off the engine. When I returned approx. 1 hour later, the engine was still running. I am concerned should this happen when I park the auto in my closed garge which is located directly below a bedroom. The engine will be running all night and the bedroom will be filled with carbon monoxide resulting in death to the occupants. The vehicle needs a time delay shut off should the driver forget to shut off the engine. The time delay could be set by the manufacturer and should be approximately 15 to 20 minutes otherwise the engine will run forever.

I was driving my 2009 chevy Impala traveling at about 45-50 mph when the "reduce engine power" message came up followed by "check traction control". The car then became sluggish and slowed down to about 15-20 mph. It then shut off without warning and it seems as though the power steering went out. I had my daughter in the car with me and thank god traffic was light because with that happening it was an accident waiting to happen. I am concerned because it seems like this has been a common problem with this car for a few years and there has not been a recall yet. Is gm waiting for someone to die. No one seems to be able to pinpoint what the problem is and I don't think it's fair that someone has to pay money to fix what may be a problem. Something needs to be done because this is not safe at all. I see a lot of Impalas in my town and it's scary to think that at any time this can happen to any one of those cars, mine included, and seriously hurt or kill someone. Gm needs to step up and do the responsible thing for the people who invested their money in the gm brand.
