general problems of the 2009 Chevrolet Impala - part 2

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.

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.

My name is james barr 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. . Read more...

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.

Tl- the contact owns a 2009 Chevrolet Impala. The contact stated that while driving approximately 55 mph the traction control sensor light illuminated along with the message "engine shutting off". Moments later the engine shut off and could not be restarted. Approximately 5 minutes later the engine was restarted and the vehicle operated as normal. The cause of the failure was not diagnosed or repaired. The manufacturer was not notified. The failure mileage was 93,683. Jft.

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. Lisa miller 1401 e oak clinton, mo 64735 660-492-2179 2g1wt57nx91158582.

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.

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.

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.

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.

I have a 09 chevy imapala and my car makes this aggravating ticking noise when I enter my car when I crank up the car when im outside and touch he car it ticks for about a minute or two. It also ticks when I have to turn the air on for the driver side I have to leave the temp or hot and when the ticking stops completly ( there is two reps of it) then I can move it to the cold side.

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.

I have been having the service engine light come intermittently along with the service traction control light. I have had a technician look at this for me and advised that the throttle control sensor (accelerator pedal) is going in and out. The accelerator pedal is connected to a sensor that drives the throttle on the engine. When this happens intermittently the vehicle looses engine power and traction control.

This is the 3rd time: while driving, speed reduces dramatically, service engine indicator comes on followed by warnings: "engine power reduced" and "service traction control". My research on the issue to find out how to fix, shows many people having the exact same problem that isn't getting resolved by gm. Engine power reduction to such a dramatic speed can be extremely dangerous for not only the operator of the affected vehicle, but also anyone else on the road near the driver.

Driving to work and the service traction control light went on then engine power reduced and throttle error and the car would not accelerate and powered down. I was at red light so I turned the car off and turned it back on the car would not accelerate so I turned it off again and waiting put my flashers on, waited a few more minutes and the car finally started to move. I took to the dealership because it's a powertrain issue and I have 100k powertrain warranty and the dealership said it's not powertrain and wanted $778 to repair, I called chevy after seeing the forums only this is a known issue thousands of people with the same complaint and chevy said they are going to work with the dealership. I have to be back at work Monday and drive through a very rough neighborhood I do not want to breakdown in that neighborhood.

Tl- the contact owns a 2009 Chevrolet Impala. The contact stated that while driving at various speeds, the vehicle would suddenly loose power and would not accelerate. The contact indicated that when the failure occurred, the traction control and reduce power sensor lights illuminated. The cause of the failure was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was 70,000. Pam.

The contact owns a 2009 Chevrolet Impala. While driving at 35 mph, the vehicle lost power and jerked. In addition, the service stability traction and power reduced was displayed across the message board. The failure recurred on numerous occasions. The vehicle was taken to a dealer who was unable to diagnose or repair the vehicle. The manufacturer was not notified of the failure. The failure mileage was unknown. The VIN was unavailable.

Was driving when the traction control light came on and message came across saying service traction control: then check engine light started flashing rapidly at the same time. Follow by a very loud knocking noise from the engine. Then speed would not accelerate. Turned on flashers and coasted into parking lot. Vehicle had troubles restarting and would not move. Steering wheel was hard to turn. Tries to die while idling after you get it to start. Did diagnostics and code p0300 random misfire detection power train unable to establish a link to the vehicle. Fuel system 2 is ol, lift at 0%, spark plug 13. 5, fuel level low 38. 8, ecu 14. 417, low acceleration. Contacted local chevy dealership and was told it will cost $35 to tow it to their shop and about $85 just to run a diagnostic on their machine. If it is a lifter the cost will be over $700 to get fixed. I purchased this automobile in August 2013 and have just had it a year. So now I have a car payment on a car that doesn't run. I bought it at wk motors in sedalia, mo. This is the second time this car has had issues and without a warranty the dealership wont do anything!!!.

While driving, I got to about 60mph and the traction control as well as tire pressure light came on and engine power reduce. I dropped to 40-45mph then system said entering trottle mode and vehicle cut in road. I pulled over, turned ignition off and waited 2 or 3 minutes then I was able to restart vehicle.

The vehicle started to beep and gauges didn't work then work. The gauges went back and forth. The locks locked and unlocked. I started to drive and didn't know how fast I was going because the speedometer didn't work. The engine seemed to work harder to reach highway speed. When I turned the car off, the stabilitrak light came off but check engine light came on. I took the car to the dealer and they cleared the codes for the check engine light but couldn't find what caused the stabilitrak light to come on. They took the electrical harness off and put electrical grease on to keep moisture out. That didn't solve the problem. I still have the stabilitrak light to come on and gauges not to work. Now, it happens when I am driving. I feel that someday this will happen and have no control of my vehicle because one time I felt the power steering to go but come back right away.

I cranked my 2009 Chevrolet Impala leaving a nearby gas station and the message service traction control flashed, then engine power reduced, and the check engine light came on. My car drove sluggish home at a very slow speed. Luckily I was only about 5 minutes from home. The next morning no message was displayed and the check engine light went off. I took it to advance auto parts and the code p2127 was displayed twice - throttle pedal position sensor. I see most of these complaints are similar to mine I just happen not to be on the highway. Is gm investigating this because this is serious with multiple occurrences?.

Traction control light comes on. Power is reduced. Car runs and drives well. Driving on interstate the light comes on and cuts power. I had to coast to a stop on the side of the highway. We waited 5 minutes and the car started. The light went off for a day and then came back on. I hear of people replacing parts and the problem not being fixed. I can't afford to do that.

This incident has happened several times leading up to the check engine light remaining on. As I would be driving down the road at approximately 45 mph. The vehicle would suddenly start to jerk to accelerate and decelerate without me wanting to change speeds. Several of these incidents have been while I was driving in traffic. Then the message "reduced engine power" and "service traction control" would appear on the dash and the traction control light and check engine light would come on and stay on. This would also cause the car to reduce its speed and cause significant acceleration problems. I replaced the accelerator position sensor as indicated by a code look up and haven't had anymore problems with the car as of October 25, 2014.

I was driving on the highway and suddenly lost speed and the engine light came on and also a couple of messages. "reduce engine power" and "service traction control". I have enconter a lot of Impala owners with the same problem, which leads me to belive is a manufactures mistake.

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?.

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.

While I was driving the service stabilitrak and reduced engine power light came on as well as the check engine light. Luckily I was going slow did not lose engine power. I turned off the car the service stabilitrak and reduced engine power lights were not lit but the check engine light stayed on. When I got in the next day the check engine light was not lit. There were no lights on no check engine for about a week and then it started coming back on again. It has started again on a more recurrent basis. I have read threads about this issue and I'm very disappointed that gm has not done anything about this. I have read threads on this issue on your website and apparently it is a problem with the Impalas.

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.

While driving the car displayed "power reduce". Then the car slowed down by itself. The next day the car lost power. Today, the car is stating the same thing and signal turn themselves on, and once the car is off the doors want lock you have to manual lock the doors. The car have been jerking while driving and making a fuuny noise.

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.

The first time was about three months ago in March 2014 but the engine never died then. It just had less power and was better the next time I started the car. Don't know what the mileage was then, maybe about 52k. It happened a couple times that same week and I was going about 40mph. I asked about it in April when the car was inspected and was told they didn't see any problems but that it might be a sensor going out. Then, on July 4th in the mountains in missouri was the next time, going about 70 mph downhill and this is when it died with like 3-5 second warning. First the light comes on that says service traction control then it says engine power reduced and dies. Nothing works except the brakes. This happened again on 7/12, going about 70 mph again, died again. Was in the middle lane on freeway and nearly got hit as my car barely moved and had hard time getting to the side of the road. The car did not die, but had very little power, steering was very hard and I felt like I was in extreme danger both of these times. This needs to be recalled!!! so many other reports of same problem not just in the 2009 but later years, where the maufacturer should already know this is an issue, but keeps making the car the same way. This is a total outrage!!! I cannot get on the freeway feeling any security and don't have money to keep making costly repairs on this vehicle. Many other problems with this car, but not safety issues at this point.

Was driving car and traction control light came on and then check engine light. Lost power and brakes. Car was able to stop but very hard. Glad nobody was in front of me or I would have it them. This is very dangerous and I think there should be a recall on the throttle body and sensors. I did have it fixed but had to take it to several dealers to figure out if it was the accelerator pedal or the throttle body. It was the whole throttle body unit.

In February 2014,the traction control and abs warning light began coming on, in my 2009 Impala, when making a left turn. The lights began to come on more frequently and would stay on for longer times. I took the car to the dealer and they replaced the left hub. This solved the problem for about a month and then the traction control and the abs warning lights began appearing again. Each time the lights would stay on for a longer time. The car is now in the shop for the second time for this problem.

What happened is the vehicle traction control triggered and reduced the cars functionality and speed. It cleared itself, but what concerns me is this problem is prevalent in gm Chevrolet vehicles ranging from 2005 to 2011. It is listed many times here in your data base to your organization. Our lives and safety are involved here. Focusing on charging a fee to do an investigation is deplorable. Lives are at stake here. This should not be another american after the fact occurrence or event. What happened to proactive responsibility. These american car makers produce junk cars and the consumer constantly get stiffed with lemons. States lemon laws? nothing but american lemons are rolling off of the production lines. You think, this may be why other countries will not buy our products. There is no reliability in what is produced or manufactured and the customer service is lip service. Non - existent with these car dealers and pure sales rhetoric. Your site reads: the information you provide will be used to identify potential safety-related defects or determine the adequacy of existing safety recalls. I can't afford the repairs, pay for an investigation as well. I am not pleased with how the ball keeps getting passed or dropped. Nhtsa these poorly produced weapons weigh tons. Rolling down the poorly maintained highways and streets of this country endangering us all life and limb. My vehicle has the same problem with the traction control that forces my car to brake , pull to the right and slow enough to endanger my well being. I'm truly scared and concerned here and the repairs and code lights aren't reliable. Only the repair shops are winning. The problem keeps repeating after thousands are spent to keep the car running. I need this car for work. If it cant get me there then they will come and take the junk back I am trying to maintain. Thank you.
