Purchased this car straight out for 4000 from deans car lot in Winchester ky over a week ago. They didn't tell me I had missing fog lights. Keyfob to far was so beat up and bent I could barely get in my car or lock my car not to mention they sent me home in that car with all 4 different brand tires and 4 different sizes. A couple tires are even plugged !! And no wouldn't help me fix any of them. They ignore me. Wasn't no crash. The car lot has been devious and I'm not happy bc that has to do with MY SAFETY. MY LIFE. MY VEHICLE. IM ROYALLY PISSED

My car has the auto shut off and when im driving it sometimes just dies while im driving with no warning and no power steering to pull over. Also when im at a red light and the auto shut off comes on when it starts back up all my head lights turning signals radio everything goes off and comes back on when the car restarts then when u go to take off it will die and everytime I push on the gas it hesitates to go if it dont die. I took my car to an independent car repair shop and they said they have tested everything and I have also replaced the front and back batteries and I was told it is the computer and he has had several of the same car come in with the exact problem.

There is an electrical issue with the vehicle, causing bad computer readings related to the O2 sensor, VVT valve/rocker arm solenoid. It causes shaking and bad acceleration. These parts were already replaced and within days of the “repair”, I am still having issues. If driving and I start to accelerate, it gets shaky and almost stalls the vehicle completely. If that were to happen while driving in the middle of the road then that could easily cause a wreck.

2015 malibu which is equipped with auto stop will shudder and die anytime you stop. Car has been taken to multiple shops to try and get it fixed but nothing done has fixed the problem. Car has become a danger to drive. Both batteries have been replaced but did not help.

My 2015 Malibu continues to have problems. I have a constant P Code (P2635) that refers to the fuel pump (Low Performance). The Malibu has the auto stop but at times the vehicle wants to lunge forward. It also at a stop not only goes to the auto stop (engine ) but cut off all the way . Which this result in having to place the car back in park to re-start. I have seen a youtube video of a hotspot (wear) on the wiring harness that is located in the right rear fender well that this blue and white wire was worn and broken possible causing this problem. Other that this issue the vehicle is good and still gets around 35mpg.

This 2015 Chevy Malibu has been serviced over 10 ten times for a stalling/check engine issue(s). Sometimes the check engine light will activate after stalling and other times it will not. This vehicle has only had 1 owner since the initial purchase with on-star showing all the times/dates that a problem was detected and reported via email (on star). The dealership has had ample attempts to fix the issues with the vehicle, as well as private ASE certified mechanic/shop after the issues continued with this problem vehicle. This vehicle is a lemon, it is not dependable, and the stalling issues seem to be an on-going issue with GM Chevy Malibu. On 05/15/2021 while in Natick Massachusetts, I was almost rear-ended after my vehicle stalled in traffic and I could not get to the BDL. As quickly as the vehicle stopped working, I was able to restart the vehicle and move it out of the road. This problem can not be ignored or downplayed, someone will eventual get hurt or killed because their vehicle stalls without reason or warning. I need a dependable vehicle and do not have the luxury to run to the dealership multiple times for an on-going problem.

In august 2019, my 2015 chevy malibu started having with the variable valve timing (vvt) solenoid -part # 12633613 (abt. 80k miles). When accelerating into passing gear, the engine would step out of gear and the RPM's would rev very high while the car slowed. I would have to let off pedal until RPM's lowered, then accelerate slowly. My local garage diagnosed the bad part and began searching for a replacement. They discovered that (1)-gm is the only company that makes the part, (2)-that gm doesn't have any more replacement parts and (3)-gm is not going to make any more. They discovered that many gm dealerships have hundreds on back order also. In december I filed a complaint with chevy customer service; case # 9-5698216592 and conversed with vahmarta ph.#(866)-790-5600 and field rep; logan ext:5916533. Their final answer: (1) gm is the only company that makes the part, (2) gm doesn't have any more parts and (3) gm isn't going to make any more parts. Their final solutin: they offered me a $2,500 voucher towards a new vehicle. Gm is quite aware that this is a problem but is not offering a part to solve the problem. I am concerned about my safety and those around me on the road. The car doesn't accelerate or decelerate properly. What is a proper solution? Thank you for your help.
