When your at a complete stop vehicle gives a hard jerk like someone has rear ended you. All of the Impala's have a failed transmission pressure control solenoid which can cause accidents when it jerks very hard causing someone to run into the back of another vehicle. No check engine light or anything will come on letting you know the problem. Years 2000 to 2015 all have the same problem. Needs to be recalled before someone seriously gets injured.

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.

Driving on interstate vehicle suddenly lost all power and would not accelerate & quickly decelerated with any prior warning. 18 wheeler almost rear ended me. Instrument panel displayed “engine power reduced”, “service traction control,” “service stabilitrak”, and “check engine light. ” finally exited interstate safely and shut down engine thinking it was going to blow up and after 2-3 tries to restart messages disappeared and vehicle seemed to be ok. Took vehicle to mechanic & found codes evidencing the loss of communication between the tac and or the app units causing vehicle to go into limp mode but could not get the condition to reoccur. Mechanic had to remove codes to permit to duplicate problem, could not duplicate and told me to wait until reoccurred. While looking for repair shop was scared it would happen again received letter from gm stating if the above condition had occurred they would fix. Called gm dealer mentioned letter they refused to repair unless the messages were present on panel, refused to look at the vehicle. Called gm customer service referencing letter, explained gm dealer refused to repair. Was told by angela issue was safety related problem but gm would not admit to safety issue. Gm agreed to pay for one hour of diagnostic time to determine if vehicle qualified for repair, dealer was unable to duplicate problem, refused to repair. Called gm and was told no repair would be made even though the problem had occurred as stated in the letter and to wait until situation occured again then not to start engine and tow to gm dealer. Was told gm would not pay for tow or inconvenience and if they could see codes they might repair problem. This is definitely a safety issue since when this occurs the vehicle loses all power and basically shuts down and will not accelerate beyond 5 mph if at all. Leo nelson 937-554-9778 noslenlsn@gmail.

I own a 2009 Chevrolet Impala. I was driving on the highway at 65 mph when the check engine light, traction control light and engine power reduced light came on. A few minutes later, in heavy traffic it said engine shutting down and there was a short countdown displayed before the engine died completely. This is very dangerous and I am lucky to have been able to get over to the shoulder without getting hit.

Driving 40mph check engine light came on then reduced engine power flashed on message board several seconds later traction control light came on and service traction control came on message board. My speed was reduced to 20mph in traffic! luckily I was able to pull over safely without causing any accidrnt (fyi I had my daughter in thr car with me). I will be taking the car to a chevy shop in the morning where im sure I will have to pay high cost out of pocket even though this has been an issue for chevy owners (online srarch) and there has been many complaints with no recall. This is a serious ussue and I feel it is putting many lives in danger and should have been a recall a long time ago. Im just lucky I wasnt on the highway yet because this could have turned fatal.

Had purchased vehicle from dealer in ashland va back in September 2014. Had no concerns about the vehicle until first trip not driving vehicle for a week and upon return vehicle would not start. Had jumped started vehicle and got check engine light which was on for three days then cut off. In February 2015 had not driven vehicle for two week period and upon return vehicle would not start again. Checked battery and had replaced along with cleaning positive battery post for corrosion. Check engine light was on for two to three days then cut off - check code at firestone dealership showed code p2135 - dealership could not determine where possible power drainage could be coming from and recommended to take vehicle to chevy dealership and have them test for power drainage. As long as the vehicle is started/used without prolonged period of inactivity, vehicle operation for this model year is acceptable.

2007 chevy Impala will have the engine shut down. The warning "engine power reduced" "service traction control" will come on, along with the check engine light. You cannot accelerate, the car shakes, and is difficult to drive. Had the gas pedal and the equivalent part in the engine replaced (at different times) and had the codes come up in between the parts being replaced and still now. Took it into a chevy dealer and it doesn't act up for them. And for whatever reason their computer doesn't show any problems. There are many complaints about this on different websites. I called gm and have a case opened to get help from them. It's extremely scary to have the engine power reduced while driving and it's very dangerous because you can't maneuver or accelerate.

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?.

While driving my vehicle, the traction control light and check engine light came on. . . Then a message stating "engine power reduced" came on. My car dropped the speed from 60 to 20, on the highway. It happened again a month later and I was told that my accelerator pedal needed to be replaced. This happened again in March of this year, and I was told my fuel pump had gone out. Now it has happened again this morning, and the mechanic doesn't know what's wrong with it because it happens intermittently so he can't diagnose it unless it does it while the car is in his possession.

I am complaining about an incident that happened to me on Saturday, June 14th 2014. I was driving about 70 mph (I have a 2009 Chevrolet Impala) when my check engine light came on. Not long after that did I notice that my engine had shut off and my power steering had went out. Come to find out today (6/17/2014), gm had an ignition recall. Since the same exact description happened to my vehicle I thought for sure that it was under the recall. I tried to call my local dealer to get it resolved, and shockingly my car did not have a recall under it. I tried to call gm directly and tell them what happened to me, but they said that they could not help me being that my car was not under the recall. My concern is that gm is not taking full responsibility for all of these incidents. Its just not right, its not good business on their behalf, and its not ethical. If any of my driving conditions had been different, I could have been involved in a lethal accident. Not only does it pose a threat to myself, but if I had other passengers in my vehicle and also other drivers on the road. Something has to be done about this and gm needs to take full responsibility for the faults that they produced.

While driving car started to jerk and hesitate the check engine light came on along with a message of reduced engine power. Could not drive the drive over 5 mph. Was able to get to the side of the road. Had to push the car into a parking lot as the engine will no longer start but cranks over fine. Had to buy a scanner to read the code because the car was not able to drive to a auto repair shop or auto parts store to read the codes. The po641 code was set. Checked and tested the sensor wires for the 5volts every one that I tested showed ok. Replaced the gas pedal assemble because of the code that could be a source of the problem no difference. Cleaned the throttle body unit no change car will not start. Checked and gave all the wires a good pull and or tug to wiggle the connectors and took apart all sensor connections no corrosion was found. All grounds appear to be good. No broken wires are found no blown fuses were found. After 2 days was able to start engine with the message reduced engine power and car died again and would restart but not idle. Was able to rev engine and keep it running but once it idled it would die and sometimes not restart again. At this time car is unsafe to operate on any roadway because it might die and random times.

One day before I was to take a vacation from missouri to texas, my check engine light came on. My mechanic told me the code had something to do with a fuel canister, but it shouldn't pose a problem. As I was driving 75 mph on the highway inside the texas state line, after 7 hours of driving, mostly in rain all day, the car started doing a jerking type action & then my traction control light came on, w/a warning msg saying, "service traction control; engine power reduced. " going 75 mph I lost all control! no lights, no a/c (which is a separate, loud, clicking issue I could address), no power steering, no power brakes! I had all I could do to just point my car to the side of the road & coast to a stop, in the middle of nowhere w/out a service station in sight! I tried 3x to restart the vehicle to no avail. As I sat there in bewilderment & fright of what just happened, I contemplated what to do. After about 5 minutes, I decided to try & start it 1 more time. This time, it started up. However, the check engine light & the service airbag light (again, another issue I've had with the vehicle since the day I purchased it) were still lit up but the traction control light & the warning messages had gone off. I continued to my destination & the following day (Saturday) I took the vehicle to the local gm dealership where they proceeded to do a diagnostic test &, of course, "could not replicate the problem," therefore they could not "find anything wrong. " they gladly depleted my vacation expenses of $100 & sent me on my way with a reassurance that "if it happens again while you're here, come back by & we will test it again but we won't charge you for it. " how nice of them. :{ gm seems to enjoy doing that. And the NHTSA doesn't seem to want to take the initiative to investigate this prevalent problem w/these cars. If something bad happens, I'll sue the pants off of them.

Our 2008 Impala LS, with 100,000 miles, is having the same problem I am seeing at this web site and all across the internet. Last month, may, 2014, and this month, June, 2014, there was a sudden reduced power alert on the dashboard and the check engine light came on. The speed immediately dropped to no more than 35 mph. Before I could get it to advance to have them check to see if any codes had been dropped by the computer, the check engine light went off. There was no reduced power message either, and the speed returned to normal. I was told to try fuel injector cleaner, which I did. All went well for almost a month, when the same thing happened again this month. This time I was able to get it to advance with the check engine light still on. The computer had dropped 2 codes, both related to the accelerator pedal position sensor. Advance did not have the part, nor did autozone. Fortunately, napa did, for $90, including tax. Our local chevy dealership wanted $50 more. Since it is a very easy part to replace even for an amateur like me, I replaced it. There are only 2 10 mm bolts to remove and an electrical connection to unplug. So it was pretty simple, and so far, this has done the trick, but it's only been 24 hours. This apparently is a job that the dealerships want to charge $300 to $400 to do. As I said, this is a widespread problem for gm, and they have not and will not, so far, do a recall. They should. I'm only out $90 so far, but other people are out much more. If I have the dreaded, follow-up problem with the the throttle body, I will be out a whole lot more. I sent an e-mail to Chevrolet after the first instance, and did get a response back. I told him I didn't want to take any further action unless this happens again. I will be contacting him again now about this latest incident.
