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.

2015 Chevy Malibu with 2.5L engine with rocker arm oil control valve malfunctioning. Check engine came on Thursday May 6, 2021 and had it diagnosed Monday May 10, 2021. 2014's have a recall, but 2015S do not and my mechanic can't even find a GM part to fix this.

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.

The check engine light came and we took the car to the dealership, where purchased new, and they ran a diagnostic test on it. The test showed that the rocker arm oil control valve solenoid was bad, and GM does not make a replacement nor is a replacement available. We have been in contact with GM concerning this, but was referred back to the dealership, who has told us their is no replacement part being made, and have left us with no options, as the car cannot be used as a trade in, due to this issue. I've been on the Malibu forum and there are numerous people in the same situation, and GM is given us all the back of their hand, with no answers. We now have a 5 year old car that we are paying on, but cannot trade in or sell until GM and their dealerships act.

While driving the vvt solenoid malfunctioned and all the oil spilled out of the car rendering the non operable. This part can not be found anywhere. I was told be the several dealships that this part has been so back order since June 2019 leaving me without a car and with a car note. GM should offer a credit back to their customers!!

It like shudders or shakes going certain speeds like gas isn't getting through or something....been happening but getting worse now

Check engine light, turned out it was solenoid vent valve, a $36 part that cost me a total of $600 usd to replace after diagnostic fees and shop fees. They had to drop the gas tank to access it. This is a premature failure for a four year old vehicle with only 48,000 km. If this is a regular maintenance item that requires frequent replacement, GM should have put it in a more accessible location so it doesn't cost $600 to replace a $36 part!

Purchased a new 2015 Chevrolet Malibu 1lt with 8 miles from imperial Chevrolet in mendon MA. At 44 miles the vehicle was taken to imperial Chevy. Service for a Massachusetts state inspection sticker. The brand new 2015 Chevy. Malibu failed the emissions portion of the state inspection test and I was informed by the imperial service dept. That the vehicle failed the state inspection and he (service dept.) did not know why the vehicle failed but I was instructed to drive the vehicle around for approx. 100 miles and after the 100 miles to bring the vehicle back and imperial would re-test the vehicle. After driving around for approximately 100 miles I returned to the dealership and the vehicle passed the state inspection after the second test. At approx. 3,000- 30000 miles (at times) the vehicle would indicate (via indication panel) that the gas cap of the vehicle was loose. The 'tighten gas cap' indicator light would come on and go off during operation of the vehicle. During several oil changes to the vehicle, I informed the service dept. Of the 'tighten gas cap' indication but due to the light not being on during the oil charges the service dept. Could not find any issues with the vehicle. At approx. 33,000 miles the "tighten gas cap" indicator stayed on and after a while the check engine light also came on. I brought the vehicle to imperial Chevy. Service and they found the "vent solenoid sticking" "code 0455" and replaced the vent solenoid. At approx. 40,000 miles the same issue started again, the vehicle would indicate that the gas cap was loose, the message would come on and then go off. At 45,000 miles once again, the light came on along with the check engine light. Once again, the vehicle was brought to Chevy for service and once again the vent solenoid was found to be sticking and the same part (vent solenoid) was replaced. Same issue 3 times.

The car was stationaried, it was about 28 degrees outside. My car was on and off in between an 8 hour period. As I am a local driver for a company out of austin, tx. January 7th at about 12 midnight I started feeling nauseous, then it quickly went to cramps thinking I was hungry I tried to eat. Meanwhile I vaguely smelled something but couldn't make out the smell inside the vehicle. At about 2am I was really bad off with now a terrible headache that was beyond a normal headache. I kept working till 3 am Jan 8th. As I clocked out I was feeling distant and dizzy. I returned to the car and drove home with a foggy feeling. I barely made it up our 3 flights of stairs and stopped halfway. As I felt I wasn't getting enough oxygen. I came inside our home at 3:15. And at that time explained to my husband my symptoms I started breathing in and out as much possible enough air couldn't come quick enough. My body was tired I took meds for my head and dizzudly fell asleep. My husband informed me that he checked the car and under the hood he could smell an odor and upon checking he could hear a whizzing from the battery." The battery had been releasing fumes back into the car he said". which was causing me to inhale carbon monoxide poison. All the symptoms I was feeling checked out as I rested Sunday January 8th. He checked my oxygen levels as I was ok now! stating the obvious it could have been deadly I was very shaken and barely mentally there but didn't realize it. As this was more than traumatizing for me and our family we are now reaching out to inform and wait to see what are next steps are!

While driving thru houston, Texas on interstate 10 with heavy traffic the engine shut off, the analog instruments shut off, the center my link screen shut off and the digital readout alternated between mph and miles traveled readout. My wife was driving and attempted to restart the engine, no result. She shifted to neutral and it would not restart. We were able to coast thru several lanes of traffic and safely stop on the side of the road. The car was shifted to park and started. We traveled approximately 200 miles to our destination and two days later exchanged the car for another rental.
