In summer 2015 while using ac, heat randomly would blast out. (while idle or driving). Would have to restart car to get ac to work again. In the past 2 weeks dec15/jan16, engine overheated-idle indicator came on while driving on the highway, once at 65 mph, once at 30 mph. Then a few minutes later it would turn off. I looked at temp gauge, and it was not at an overheating level (half way only). Also, now heat only intermittently works. I will have to turn car on and off repeatedly, and turn ac on/off, heat on/off, defrost on/off, and sometimes the heat will finally get warm. Never seems to get hot like it's supposed to. Took to repair shop for the engine overheated/idle warning and stated nothing was wrong. Safety issue not having heat for front windshield defrost when it's under 30 degrees out. Mechanic said it's probably a computer issue with the car. But now I'm seeing this is a recurring problem with many car owners. GM needs to recall, as this can be a safety concern!

Driving 55mph on cruise control, I heard a warning chime. Looked at dash and the words engine power is reduced were on the screen. I looked for a symbol on the dash to tell me more and saw the engine symbol was on. The car didn't perform out of character from already going 55 on cruise. Nothing changed in the engine performance. I continued toward home as that was my destination and was less than 15 miles from home. I parked the car in my garage, turned off the engine, waited a few seconds, then started the engine again. The warning came on right away. I called the dealer who I'm leasing the car from but it was a Saturday afternoon and they were closed. I did leave them a message to call me on Monday and why. I have not and will not drive the car until I hear from the dealer and have a date and time to bring it in because of the concern the engine could power down as I'm driving according to internet forums I since read that others with the same warning said their car did slow down on a fast busy highway. This warning is in the manual that came with the car and says it is the throttle body sensor gone bad.

My vehicle which was purchased brand new 02/2014 was left running and placed into park on level asphalt street. When I walked about six or seven feet from the vehicle my vehicle began rolling forward. I chased the vehicle and attempted to get inside to stop the vehicle. I was able to open the door but was dragged several feet. I could see clearly the vehicle was in park. The vehicle went in to a small ravine and from the outside of the vehicle I was able to push the engine stop/start button and the vehicle stopped. I easily backed the vehicle out after starting it. I shut the vehicle off and some nice people I did not know tended to my injuries. I called General Motors later that night and was given a service request number of 71-1320790919. My vehicle was towed to sunrise Chevy on 06/22. On 07/21 I was notified nothing could be found wrong with my vehicle. I was given no paperwork from General Motors or the dealer. There was $1100 dollars of damage to my vehicle. General Motors refused to pay for said damage. I was told to use my parking brake. Really that is ridiculous when U are on level ground. My left foot and leg still show the signs of being dragged. I was also asked how many times this happened. Isn't once enough. I surely did not try to duplicate it. I did not nor will I ever leave my car running again and walk away. I had the key with me on that day but guess what I discovered the vehicle can be driven away even while the key fab is with you. I hope this does not happen to anyone else which is the reason I reported the incident to General Motors and now documenting the incident here.

I started the car and viewed the message "service power steering" in the message center between the odometer and tachometer. There did not seem to be any issue with the steering, but wanted to get it checked out by my local dealer since it was less than a half mile up the road. As I put the car into the gear, the car would not move. The indicator lights that normally show me what gear I am in (prnd) were blank. Then all of the sudden, the car surged forward violently, as if the Malibu was just rear-ended. I then turned the car off and restarted it. The "service power steering? message appeared again. However, the ?check engine? light had lit up, and the ?service parking brake" message appeared as well. The car then surge violently again forward without shifting into any gears. I then shut the car off and called spencer Chevrolet to tell them I was going to have the car towed to their shop. After a few minutes, I tried once more to start the car and was able to shift into gear and drive it to the shop in limp mode with half the warning lights lit up on the dash. After further diagnostics, the maintenance manager at spencer Chevrolet informed me that the transmission computer module (tcm) had failed and needed replacement under warranty. This was the third electrical issue I had with this vehicle (the trunk was opening on its own while driving, parked, or during the night, and the radio was locking up with no control). I was worried that the transmission issue could have happened while driving, and didn't want to take any risks.

- New Paltz, NY, USA

Steering became sticky stiff in 12 O'clock postition, making steering corrections difficult with overcorrecting. There is definitely a problem that could be a sever safety hazard. I was traveling on I-75 at 65-70 mph when malfunction occurred. I contacted a dealer in tampa and they did not seem too concerned, hard to communicate due to it being a holiday weekend. The tampa dealer advised if there was a problem, I would have received a recall letter. I am concerned, being on vacation, for the long trip back to knoxville. Also, I have experienced transmission shutter at low speed, intermediate problem.

Vehicle sold and delivered with an open active safety recall (13142) on it at time of purchase, which was a violation of federal law title, 49 subtitle vi, chapter 301, section 30112A3 restricting the sale (and/or introducing into commerce) of a vehicle with a safety defect. This information is consistent with the information in GM recall bulletin #13142. Dealer sold have not sold or delivered the vehicle until the recall was addressed. Dealer/Chevrolet risked the safety of the vehicle owner and general public by placing it into commerce with the open recall.
