This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Randomly I receive the message "service traction control - engine power reduced" - there is no rhyme or reason. It happens on nice days, rainy days, whether or not I am going uphill, downhill or on flat surfaces. On at least one occasion while driving on the highway, the engine shut off and I had to coast from lane 2 to the shoulder. After 20 minutes, it restarted.
The stabilitrak is making the car shake and act crazy. I'm barely in control of the car. There are thousands of more people having the same problem. The car reduces speed because of this issue. Many groups and blogs online about this. Why hasn't anything been done about this? no recalls or anything.
Takata recall. When vehicle is started a loud screech happen every time vehicle is started, once vehicle is in motion on highway, street, city.and in motion the vehicle starts alarming and lettimg me know in the information widow check tire monitoring system with tire pressure light consistently on then vehicle alarming sounds again to check stability trak and then it alarm S again with the check engine light that the vehicles engine power has been reduced and vehicle is no longer able to pick up speed right away this has been going on sense I purchased it. Also when im making turns the vehicle will alarm about having stability trak serviced
My vehicle experiences an 'engine power is reduced' message in addition to losing capability of driving faster than 40 mph likely as a result of a common fault by the manufacturer.
Traction control and the stability trac reduces the engine speed under normal weather conditions drastically without any warnings. Been acting up for some time. Dealers don't know what the problem is and doesn't give a code. Very dangerous and frustrating.
Engime power reduced seevice tractuon control. While driving power is cut to near nothing. About 20 mph. After shutting the car off and starting a few hours later it's fine. A couple days later it happens again. Faulty equipment from GM.
All 4 doors lock and unlock intermittently when pressing on fob or button on door. Has been happening for a few years. Noticed this is a very common issue on 2008 & 2009 Impala models, very expensive fix
I was told from a mechanic the car has either PCM or ECM problems. The car starts to die out when I'm driving it then I have to turn it off then restart it. It jerks really hard when driving it. The oil pressure low stop engine message comes on. It just has a lot of electrical problems and the mechanic told me the other Impala like mine are having either all the same problems or some of the same problems. Recall
While driving my car for only two minutes, the reduced power sensor came on and traction control came on also. My car would not go above 20 mph. Went back to normal after an hour. Very concerning if I was on the interstate when this happened.was on a back country highway when this happened.
While driving my car my car stalled as if it was in neutral. I stopped and tried to put the car in park, but nothing happened. I tried reverse and the car wouldn't move. It crakes up but there are no shifting of gears. I had to replace my gas tank as well as my pedals for this car. Please help.
I started see a warning light on in my car that read "engine power is reduced, service traction control" so I sent GM an email regarding this and maybe a month or so later I received a notice that said the gas throttle sensor will cause this to appear when it is bad. They advised if I felt this was the problem I could take it to a GM dealer and have it check, but if it wasn't they would not cover it and I would be responsible for the cost of the diagnostics test. I took my car and took my car, along with the notice to sunrise Pontiac on 12/31/15. I was told that I needed a thermostat a gas pressure sensor. The cost to repair these items would run me almost $900 and I could not afford that T this time. I asked the technician, which could I get away with not fixing right now and he said I needed to go ahead and replace the thermostat to get the check engine light off. I had that work done and the light still was on, as well as, the warning lights. So I contacted GM again and advised them of the situation. They paid for me to go to serra Chevrolet to get another diagnostic done. This time I was told I needed an app sensor, gas pressure sensor, thermostat (which had already been replaced), and a temperature sensor, all of which would run me $1300. I told them I could not afford that and left. I contacted GM once again and explained what was told to me and asked why the sensors would not be covered when they were apart of the gas throttle body? now I'm getting a warning that says "starting disabled service throttle " and my car is literally cutting off while I'm driving. I feel like this is a matter that GM should be willing to repair for their consumers to prevent accident or death. I 've read on google that several Impala owners are experiencing the same thing. Also, while I'm driving my gear control is popping out. This is my only means of transportation.
This vehicle has been recalled due to air bags, and in a year no one has been able to get the repairs done to the vehicle. But furthermore the car has several other mechanical issues that I am showing as a trend with Impala being that my sister and cousin have one also in different years, the car makes a ticking noise when the air or heat is turned on the passenger side delivers opposite temp as the driver so if air is on the passenger will deliver heat and vice versa. If the car goes over a speed bump the engine reduces power and service stabilitrak appears across the lighting as well as the car dropping out of gear if I go over any bump. This is very dangerous especially being that my children and I were in this car and it decided to do this on the interstate at night in 70 mph traffic. After doing research on the vehicle I am showing that I am not the only person with all of these problems listed, and it bothers me that none of these issues have been recalled just as the air bags were even though I think the recall, is just to save face because no one is actually doing the work to get them fixed. At first I thought these things were just mechanical problems with age of car but after research these are issues that are in cars made in this time frame and warrants a recall for the safety of consumers.
2006-2009 Chevrolet Impala ss ticking noise, engine misfire and/or ses light. This may be the result of an afm (active fuel management for displacement-on-demand) lifter that unlocks as soon as the engine is started or one that is mechanically collapsed/stuck. If an afm lifter unlocks as soon as the engine is started, a ses light and dtc P0300 will be experienced with engine misfires on cylinder 1, 4, 6 or 7 but it is unlikely that any noise will be experienced. If an afm lifter is mechanically collapsed/stuck, a consistent valvetrain tick noise, ses light and dtc P0300 will be experienced with engine misfires on cylinder 1, 4, 6 or 7.
My daughter was driving my car on a city street. She stopped at a stop light and as she was preparing to accelerate the check engine light came on and a warning message flashed stating (engine power reduced). My daughter stated that the car would only get up to 40 mph and RPM gauge would not go pass 2, even when she pressed the gas pedal down to the floor. She had to drive the car for 10 miles in fear that the car was going to stop in the middle of the city street while in transit. She finally made it home. However, the car speed remained at 40 mph; despite her attempts to increase the speed. After 2 hours had passed, I started the car-the check engine light was off and when I drove I was able to drive faster than 40 mph. After driving around the block, the check engine came back on. I contacted onstar for an engine diagnostic- the result was that the powertrain system has failed- a malfunction of the electronic throttle control system. After I received that message, I checked on line for a recall- I discovered several similar problems with 2008 Chevrolet Impala- only the government issued vehicles with similar problems were recalled. Why"?? this is a very serious issue/concern/problem. Will it take multiple tragic car accidents before a recall for this specific problem" my car has approximately 128,000 miles- and in the complaints, I noticed a complaint that had the same mileage documented. I'm terrified to drive my car for any distant and I'm also concerned about the price of the repair. I recently had a tune-up at serra Chevrolet in madison, tn (Oct. 2015)that cost me over $600. Supposedly, the fuel injection system was serviced. I wondering why I have this problem. I strongly feel that GM needs to recall this model vehicle along with the 2008 Malibu for this problem.
Stopped during out-of-state trip and then ESC sensor lite came on and car would only go 20 mph. GM dealer in nashville not much help. Repeated pushing of tc/ESC button finally cleared fault. Now hesitant to drive this car. Last GM car that I will ever own.
(reduced engine power) my 2008 Chevy Impala randomly shows down after the dash reads reduced engine power. I am lucky to be alive I was doing about 60 on the expressway and the car speed just dropped to 20mph I had to swerve because the car behind could not slow down in time. My two year old was in the car and I hear that GM cars have this problem all the time. This is ridiculously dangerous someone has to do something about it. The GM dealership has no ideal how to fix this.
While driving my vehicle, I went to make a left hand turn and the traction control service message apeard along with ABS lite and engine reduction causeing my vehicle to almost stall out on a major highway.
