My son was driving his vehicle and the computer assisted power steering went out. Fixed at doug Chevrolet 1-12-2018. Now (after the warranty repair of a steering shaft torque sensor) when driving four days later he lost power, vehicle flashed service traction and reduced power and slowed immediately from 45 to 5 mph and he was able to limp it home. The loss of power while driving was immediate and drastic and cars behind him were able to slow down but it could have caused a severe accident.

My engine light has been on since I purchased the car back in 2014 the dealership said it was no big deal that the light would evenually go out. Upon purchase it had 51,000 miles on it, because they had it for a few weeks due to it having hail damage the finance company wouldn't approve the loan because of problems. The car was riding ok up until a few montha ago I noticed I was loosing power it was driving slower, I started feeling it tugging when I wanted to pick up speed. Then 3 days ago it just wouldn't go in reverse, when I tried to switch back to driving it wouldn't go into drive ultimately I had to have the car towed because the tranmission went out on it. The car only has 71,000 miles on it. I barely drive it anywhere. The engine to look at it is very clean. I looked up all the recalls on my car and none of them I was notified for and there are many. So why am I not getting a letter about this transmission that has obviously gone out. Up until now I was in love with this Chevrolet Malibu and was a devoted customer advising people this was a good car, now I'm not so sure. Looking at all these recalls are alarming.

The incident happened twice thus far. Once while waiting at a light and another time while driving. The car began to shake and the engine light, as well as the stability control lights flashed on. The car began to rev erratically and actually caused the car to move forward. Some messages began to come up on the dashboard display and the message that remained was engine power reduced. Trying to take off from the light to find a place to pull over the car was jerking and I could barely accelerate. While driving this slowdown and jerking happened suddenly and almost caused a collision with another car. After pulling over and shutting off the car the problem disappears for while before happening again. Once parked, opening the hood showed a violently shaking engine. A simple google search revealed that this is a frequent occurrence with Malibu around that time and the mileage I have on the car (66500). The culprit appears to be a faulty throttle body, from the experiences of other drivers.

1/26/2016 I got my camshaft solenoid fixed due to my check engine light coming on. When it started to shake real bad with the dash lights stating that my engine power was reduced, loss of traction (something to that effect) I instantly put it in the shop. Then last week 3/4/2016 I was driving up to erie, pa from Ohio, which is about 4.5 hours away. I say a good 40 minutes from my destination it happens again right on the highway. Engine light comes on and the dash says that my engine power has been reduced and loss of traction (?). thankfully there was an exit near that I could get off at and as soon as I put my car in park it started to shake real bad. So I did what I did before and turned the car off to let it reset and then started it back up. It ran fine for the remainder of my stay until it came time for me to leave to go back home. This time I only got 20 minutes away from erie before it started acting up again, but it kept doing it. Talk about being frustrated 4.5 hours away from home in your car. Especially since I just got it fixed not too long ago. This needs to be on the recall list, because this is ridiculous.

- Langley, KY, USA

The other day my 2011 Chevy Malibu started to violently shake coming out of a parking lot and then again while driving on a two lane road. This issue was frightening because I couldn't properly stop the car and almost got into an accident. The display indicated reduced engine power/traction/service ESC and the obd2 codes indicated P2135 (throttle/pedal position sensor/sw A/B voltage correlation). The Chevy dealership replaced the throttle body. I hope this does not happen again because the next time I may not be so lucky in getting out of this predicament unscathed.

My 2011 Malibu while on the highway through a sensor code for multiple problems the first stating reduced engjne power, then service ES, service traction, service airbags etc... probably 8 codes. At which point on the highway I could no longer accelerate above 40mph creating a very dangerous situation for me. The car was jerking and shaking and the RPM was reving up between 500 and 1500 even after I stopped. I turned the car off fearing damage to the engine and called myhusband. He asked me turn it on again so I did and although it was now idling normally the engine light remained on. He suggested I continue my commute. I pulled back on to the highway and experienced this same dangerous problem 7 yimes between jackson mi and lansing mi. We took it in to a repairshopand they assessedwhat they could stating that it appeared to be a throttle body issue but they would have to take it apart to look at it. The mechanic also statedthat many of the Chevy made vehicles have had this problem and he was very surprised that therehad not yet been a recall on the part.
