Engine Shut Off Without Warning problems of the 2009 Chevrolet Impala

The vehicle shut down and I cannot start it because of the ignition switch causing the entire vehicle to become inoperable. I was pulling up in my drivewaywhen the vehicle shut down.

Earlier this year my car started flashing a "reduce engine power" and "service traction control" together. My car sounded like it was working harder too but I was city driving less than 30mph so I didn't otherwise notice problems. This happened rarely. A few months later I was on the freeway just getting on (flat road) and the warnings came on suddenly. Then as I got over 40mph, my car engine shut down and my steering wheel locked. Luckily I was able to make a slight turn off my wheels enough to get to the side of the road. My car flashes these randomly after random lengths of time of the car being on and driven and it's almost a daily occurrence. I've seen online no one has been able to solve the issue.

The Impala displays service traction control followed by engine power reduced. Throws a code for throttle body sensor, but that does not fix the issue. Accelerator pedal position sensor is another reason they say, which also does not fix the issue. My car has shut off on me going down the interstate, on a highway, and and over a hill. It shuts down and says �starting disabled, service throttle� with no warning at all. Several people have had the same exact problem and no one seems to know how to fix it. They say wiring but it never fixed anything.

What has to happen before something is done about this problem ? traction control light and reduce engine power light comes on going down the interstate and the car shuts down and you have to try and get car pulled over to the side of the road without hitting someone or getting hit . This is a very common problem with this vehicle and nothing is being done about it . I would really like a response on this problem . This happens a lot so your date you want incident happening is really not right .

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.

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.

Tl-the contact owns a 2009 Chevrolet Impala. The contact stated that aprroximatley 65 mph, the vehicle stalled and shut off without warning. The vehicle restarted after numerous attempts. The engine power reduced warning indicator illuminated continuously. The failure had occurred on several occasions. The vehicle was taken to a dealer but was not diagnosed or repaired. The manufacturer was not made aware of the issue. The failure mileage was 50,000. The VIN was not available. Ddr.

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!!.

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?.

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.

I have had numerous problems with my 2009 Impala. From the very beginning with only 100+ miles on it and the problems continue today. The dash will say reduced engine power and as I was going down the road at 55 miles an hour my car just shut off. I was able to get it to the side of the road and just sat there wondering what was going on. It wouldn't do anything, it was just completely off. I was about to call for aaa and tried one more time and it started. This happened again in November of 2013 as well and I was going 45 on a country rd. Again I was able to pull to the side and sat there and waited again. When this happens the car will do nothing. I have problems with my traction control, making a strange grinding type noise and bogs the car down from moving when I am trying to accelerate from a stop or trying to turn either left or right. I have had problems with my air bag lights coming on and telling me to service my air bags. It comes on and goes off and comes on and goes off. The dash light will come on and tell me to shut engine off now for low oil pressure, this has happened for 4 years, the car is 5 years old. This car was never a good car from the very day it came off the lot.

I was driving down a very busy street looking for a restaurant and my car made three dinging sounds indicating a issue. Before I even could read what was displaying on my information panel the car lost all power steering and engine power. Because I was traveling at about 55mph I could very luckily coast to a parking lot near by. After coasting to a parking spot I put the car in park and read the information panel, it read reduced engine power, service stabilitrak, and service throttle body. Because I know most american made cars are pure garbage I wont drive one without a ebdii scanner. After reading the ebdii scanner it showed a p0601 code, which indicates a pcm memory issue. After clearing the code it started right back up and drove for about 10 more minutes until I was at a parking lot on a steep grade. The 3 dings happened again and my engine shut off causing me to roll backwards about 10 feet almost into over vehicles. I have done some research on this and have come to found that this is a engineering fault caused by to much current flowing into the power control module, which creates a small hairline crack on the pcm onboard computer, with which many many other gm products have experienced. I feel a recall should be done on all gm products affected by this, this is very unsafe and I feel could lead to deaths. I am a 21 year old male who could control the vehicle with no power steering, imagine a student driver encountering this issue and not being able to maneuver the vehicle away from other drivers or even innocent pedestrians! I know for a fact this has happened to many other gm vehicle owners so does a body count have to stack up before a recall is issued by gm??.

Engine light comes on and reduce power warning comes on then engine shuts off.

I had just turned onto this road, had not even gone a mile. No speed, no black marks, car shut down ran off the road and hit a tree stump. Total the car. The steering wheel was bent almost in half. I have pictures of the car. I got this car new, so all miles we're put on it by me. I broke my hip, back, knee, dislocated my elbow, crushed my ankle and foot. Had a head injury, a deflated lung. I was in the hospital for two months and a nursing home for a month. I have had 14 surgeries. Still not able to work or do a lot of things for my self. With the recalls showing the issues of the engine shutting off, I need this looked into.
