I was driving on the interstate and a message came up saying "engine power is reduced". it was during rush hour and I almost got rear ended because my vehicle slowed down to about 15 miles per hour.

While driving the electronic stability control light comes on. Power is lost. Have to stop, turn car off and turn back on. The engine light still stays on. This has happened while driving on city streets and while stopped at a light. This has happened 3 times in the last month.

I was driving on I-695 (in baltimore) with my 3 daughters I received "service stabilitrak, traction control, engine power reduced" message while driving around 65 mph. The engine and tracking light came on and the messages would not go away. I was frighten and hopeful that we would not only make it to our destination but then back home again. Fortunately we did but the very next day I have researched this issue. It seems to be a ongoing issues and maybe cost me hundreds of dollars to repair. That makes me nervous because I am a single mother with only one source of income.

Sudden displayed message while driving: Service stability control, service traction control, reduced engine power. Car was unable to go after stop. Parked the car and restarted with just an engine light, but messages started to flash again. Did get me home.

Car threw message saying reduced engine power, service traction control and service stabilitrak all at once. My car would not go and was losing speed while I was on the interstate. I was forced to pull off at a heavily traveled part of the road and wait for assistance. I had to have my car towed and worked on. The mechanic said that it is possibly a bad throttle body. I have had this same thing happen two other times within less than a year. I would like it to be noted that this time it left me in a dangerous situation. I went from doing the speed limit which was 70 then it gradually decreased in speed until it would no longer run at all.

When coming to a stop my ABS service stability traction control service brake lights all come on then my 2011 hesitation to stop when braking. Even if I go slow or just stopping at a stop sign. It pushes my foot from the brake. A cranking noise sound. I have gotten brake, tire rods, roaders and new tires. I don't know what else to do. This happens specifically when on the highway when having to come to a sudden stop. I almost crashed several times not being able to stop. Mind you my car only has 65000 miles on it. This is just too soon.

Why is there not a recall on stability traction control? I see thousands of complaints on the internet for GM vehicles. It seems to me that GM just doesn't care enough after the sale. I just bought 2011 Impala and now the stabalitrack service light keeps coming on while going down the road. It will do this for no apparent reason but happens mostly when accelerating. Using the cruise control on level road and dash warning light comes on and throws car out of cruise, decelerating while gages flip around all over the place. Power loss and lack of acceleration are definitely safety issues. Pulling out of my driveway onto Michigan highway and I get halfway across highway and car stops. This highway is 55 mpg and while I would have had plenty of time to cross the lane, car looses all power. Looking on the internet gives no help for a fix. I turned the stability traction control off, but the problem does not go away. I see on the internet that many people have taken there vehicle to the dealer garage only to get charged exorbitant prices for "possible" that do not seem to help. GM should get this figured out and not let every dealer garage do their own guessing on what will fix this very dangerous problem that is not limited to single model or year but spans many years with many models. My first vehicle was a GM but this may be my last GM. I would like to give a date below but this has been happening since I bought the vehicle about a month ago and getting steadily worse. I have had it checked out but nobody can give me any useful answers

The check engine and stabilitrak light has come on and off several times and also causing my vehicle to slow down. I am now at the point of desperation as this morning, while I was on my way to work, the lights came on again, only this time the car turned itself off but proceeded to roll even with me attempting to put on brakes. I have read in several forums that this has happened to others, including someone crashing into a light pole. Please advise what can be done, as I now fear for my life with this car.

Reduced engine power, service stabilitrak and traction control. Spent $300 to get the gas pedal sensor replaced 4 days ago and its doing it again. Car loses power (I was I-65 going about 60 mph). Shifts hard, too.

- Indianapolis, IN, USA

I will be driving, sometimes on the highway at high speeds, and the check engine light will come and say "engine power reduced" "service stabilitrack". the engine fastly reduces speed and I am unable to accelerate. This is very dangerous and could cause an accident.

My Chevy says stabilize track then engine power slows it's very dangerous should be a recall.

On two different occasions, once about a year ago and again today, my 2011 chev Impala ltz displayed a series of rotating alert messages -- 1. service traction control 2. service stabilitrak 3. engine power is reduced. I was driving about 45 miles per hour on an open road when all of a sudden the engine started running very roughly and slowed down and the above 3 messages repeatedly displayed one after the other. Also 2 yellow lights were flashing and then remained on -- the check engine light and the traction control light (I think). When I reported this problem to the chev dealership a year ago, I was told that because the warning lights and messages could not be reproduced in the service department, there was nothing that they could do. (and I understand that if it isn't broken when I take it in, the service dept would most challenged to fix it.) today, when this happened I was able to get the car to a safe place to park. I turned off the ignition, waited a moment and then restarted the car. The same 3 messages were displayed with the two yellow lights staying on. When I restarted the car 3 or 4 hours later, only the check engine light is displayed. The 3 referenced alerts were not displayed. I am getting ready to take the car to the dealership again with this problem. Do you have any advice as to how to proceed?

When taking left turns the car makes a loud grind noise then the stability controll will turn on. Now the check engine light and stability controll light popped on while driving while also having engine power reduced which then applied my brakes causing me to almost go off the road.

I have been experiencing a reduced power reading in my car. It comes and goes at will along with a stablitrack warning. I have replaced both front wheel hubs and the position sensor to no avail. This can happen driving or just going from the brake to the gas.

It was driving on my way back home. Then the engine light came on the dash said reducing engine power but then the traction control light came on and and the ABS light came on so when I got home I park the car and left it alone that day..the next day I turn the car on and the ABS light is on and the traction controll light is on I drive the car it feels like if the brakes are on I hear a noise outside the car so I take it to a near shop and they tell me its a bad wheel router so I chage it for 180 and it wasnt that so I see alot of Impala dealing with the same problems

- Houston, TX, USA

Traction control light, stabilitrac light, and engine light all came on while driving down highway. This caused the car to start jerking and shifting hard, also engine running like it has a misfire now. Before this began the car was running and shifting perfect.

June 8 2013: When driving, noticed on the freeway, it wasn't smooth at times. The transmission's shifting was pretty rough. No indication of any issues popped up on dashboard. When arriving at freeway ramp, it felt like I was hydroplaning, but on gravel. Then, noticed when pressing the accelerator, was not going anywhere, but felt like I was in neutral. Was able to pull in and take a look... transmission fluid was fine... nothing popped up on the dashboard. Nothing! the indicators for tires, oil, etc were showing info, but nothing to indicate it had died!! dropped it off at the dealership - had just bought it in July 2012. 11 months later, this"!?!" they are saying they have never seen it this bad, even when compared to other ollllllder cars, this was the worst. They have to replace the entire transmission. They called in the GM people to take a look at it.their auto trans concern: Customer states towed in transmission will not move at time of write up reverse and forward working input and reaction carrier excessive clearance metal in torque converter., valve body, burnt clutches call tac case #71-1194752825 prive comp advised to replace trans due to cost with srta. Ord serial #619asbwjr6J prelacw tih srta flush code 693ffee5 they replaced it under warranty... total cost was $4400 Aug. 29, 2017. The replaced transmission failed. We were on the freeway, just got off, while in motion, there was some really rough vibration. Could not go any faster than 25 mph. No light indications on the dashboard. It tells me if flat tire, blinker is on, the temperature outside, etc etc, but nothing wrong with the transmission. I'm not sure if it's related, but we smelled vinegar every time we started the car for about 4 days straight. We noticed that when accelerating, it's okay, but when letting off the gas on the freeway, it "shudders."
