2018 Chevrolet Malibu Complaint Log

Car hesitant to crank, once the Start/ stop button is pushed, the car will start, run smooth for a second or two then start to shake and putter like it’s not getting fuel and loses it power and cuts off. I have to go through this process 5/6 times before the car will stay crunk. While driving Car will out the blue say reduced engine power and acts as if it does not want to pull or it is losing power! The car also has the eco saving feature where it cuts off at every stop and there is not an option be turned off and car is hesitant to start back up after it cuts off. Car is now starting to smoke from the tailpipe. The VVT intake and exhaust solienoids have oil getting into them and the PCV valve is about to crack open. The car throws codes like rich fuel intake, something to do with the catalytic system (in which I’ve put a brand new catalytic converter on the car and it did not solve the issue) it also throws codes about a throttle and cam sensors and a few more codes.. I see where there are recalls for the (same make, model,year, and engine size) but my cars VIN is not included with the recall! Can we please get this as I need my car and need this issue fixed as soon as possible as it is dangerous for me and my 2 year to travel in this vehicle.

Check Engine Light constantly comes on . Pedal position sensor is faulty. engine power reduced pops up

Vehicle will not stay started will stop when ever even while driving. I haven’t driven the car in 8 months because it’s not safe.

Purchase car in December 2018, had 3 engine replacement. I am currently in the 3 engine replacement. And still experiencing the same issue - check engine light permanently on for 2 months now. Issues A whistling sound from an opening vent in the hood since last engine replaced. Call stalls, reduces speed and jerk when trying to accelerate . Have reached out to Reed lallier Chevrolet they making it seems that normal and ok. I am scared to drive and cause an accident because the car stalls before picking up. When you put the car in park, the car still not registering at park it is still moving you have to sit and clear the dash board (shift to park, even thou it is in park). Chevrolet only gave 1 engine replacement and $100 gift card. Every other expense is on me, when I still have to pay for the lemon. Unable to locate most recent engine replacement sheet. But can retrieve from dealership if needed. This car is full service and maintained in the allocated time frame reed lallier has the file of needs be.

Cam-driven Brake Booster Vacuum failure without warning. My engine died, my brake pedal and steering wheel stiffened, while in moderate traffic. I had use excessive brake force to slow my vehicle to a stop. Currently have 78,012 miles as it is sitting in the repairs shop. This is the first time it has happened, but I worry it may happen again because upon further research, it is a very common part failure.

The car continuously is throwing a code P2138 and a warning comes up on dash saying reduced engine power. This happened 6 times to me yesterday wherein I was traveling on 1 lane winding roads in my neighborhood so the speed drops from wherever it is down to 10mph instantly. On 1 lane roads in the area where I reside there’s no safe place to pull over. This is extremely dangerous and a massive safety hazard and risk to my life!

After shifting gear into park, notification on instrument panel reads Shift to Park. The vehicle does not completely turn off. This happens intermittently and is becoming more frequent.

While picking my kids up from school my car suddenly lost braking ability and I heard a weird noise under the hood. Like it needed an oil change. Tension from the brakes and couldn’t stop when tried. Definitely gained anxiety from this event. I did get the part replaced however I’m concerned for the engine and any possible damage that may have been caused. I still have the original part to the vehicle as well.

When putting gear shift into park the driver display on dashboard said not in park. The car would not fully shut off causing a safety problem. Could not lock vehicle. Was draining the battery. My extended warranty covered $382.59. I paid $177.32.

2018 Chevy Malibu over 5 times this happens since we bought it brand new it has "Reduced Engine Power" error come on and the car can't accelerate over 30 miles per hour. This is a continued problem all the time and very dangerous when we are on the tollway that has a 70-mph speed limit, and you can't get the car to go over 30 mph. This same problem happens on our 2017 Chevy Malibu that we bought brand new since we owned it too and I have already put in a complaint filed today! This is extremely dangerous and takes you a long time to get home when you can only go 30 mph or less because of the "Reduced Engine Power" Limit. GM needs to recall these Malibu's and fix the dangerous "Reduced Engine Power" error because it's dangerous to the driver in rush hour traffic and on the tollway traffic with no ability to go over 30 mph. All these Malibu's need to be fixed properly and its GM's responsibility to ensure safety for their customers lives.

I paid a significant amount to have my car fixed after bringing it initially the first time in May. Since then I have had to return my car multiple times every other month because the engine light continues to come on and they don’t know why. I have worked directly with JR and have gotten no result. The engine light continues to come on and they continue to not be able to know why, they keep my car for multiple days and can’t explain why the light is on or what they did to remove it and then it comes on a few days or months later with the same issue that they cannot explain. I bought my car in over five times already I have contacted corporate to no avail. When I brought it back the second time they claimed a bunch of things were wrong with it that weren’t wrong the first time, every time there is a new issue but they can’t describe what is the cause of the issue or can they give me an explanation on what keeps happening the last time they claim it was an electrical malfunction but could not explain any details and waited until they were closing to contact me. My engine light has since come back on which means I would have to bring it in again. I contacted corporate they were supposed to call me back, never heard from anyone. I’ve been working directly with JR who I constantly contact and he does not follow up at all or call me back like he says he would and the issue continues to happen and he is very aware of it for my initial review. They have to leave my car there for multiple days to not get updates to not get any information, they don’t look at it they don’t even know what’s going on with it, it doesn’t even make any sense at all now I’m driving a car that could potentially be unsafe and I’m bringing it to the only dealership that is closest to me Chevrolet and they can’t even help. My car is a 2018 Chevy Malibu that I take extremely good care of yet no one knows why the engine light keeps coming on.

MOTOR DIED GOING DOWN THE ROAD Car is available for inspection If I had been crossing the street without the aid of a stoplight, I would have been T-Boned Vehicle problem has not been reproduced or confirmed by the dealer. Vehicle component has not been inspected by dealer or anyone else. The check engine light and logo came on as the engine was shutting down. I went into the trunk on the passenger side and shook and twisted the wires going into the control module mounted to the trunk wall. This was suggested for the 2016 Malibu which had a recall. There should be a recall on the 2018 also. After repeated shaking and attempting to start the motor, it finally started. I drove it home and parked it. When I went to read the code, the engine started and ran for a couple of minutes and stalled again. The code was P2BB3.

My car will stop and have no power now the heat shut off and won’t come back on it’s just doing some crazy stuff I looked up all the recalls for 2018 Malibu and it was a lot so why mines isn’t listed

I was driving app. 41 miles per hour in heavy Friday traffic on 10/7/2022 and the check engine light lit up and the car dropped to about 20 miles per hour and would not pick up speed. The rpm was staying on about 3000. I pulled over and called my husband. We set for awhile and restarted the car and the light went off and it drove as normal

I received a recall letter in 2019 for N192221960. The engine control module software needed to be updated. I have taken my car to the Moran chevy dealership on Gratiot perhaps 3 times before. I was driving yesterday, Oct 4th and my car did the same thing again: Reduced engine power while I was on the freeway. It would not allow me to accelerate past 40 mph very dangerous. They informed me that the repair would not be covered, which was surprising to me, because I thought with that frequency it would be. Each time they told me it was something different. This time I am being told that the price is $862 ECM needed work, and oxygen sensor and fuel injector services. I then received a call letting me know that the price was reduced to $693 and that the ECM was updated already (after I had called letting them know I called GM direct about the recall and was waiting to hear back).

My car just stopped in the middle of the road , and would not start again for a few minutes. Then is was in low power mode , no brakes either after that , found that problem to be a bad Vaccum pump , which G M didn’t even have , and a faulty Accelerator Pedal sensor !

I was driving around 50 MPH and the car began to sputter and it wasn't getting in gas. It slowed down to 20 MPH and I had to stop on side of road. It behaved as if it were out of gas, but it had a qtr tank of gas. It would not start after I stopped it. I took it dealership and they still do not have an answer. There should be a recall on this. Numerous reports that are similar to my scenario.

On 9/22/22 I drove 2018 Chevy Malibu about 3 blocks and low fuel light displayed. The gas needle went past E. I had about a quarter tank when I last drove it. I drove about 2 miles, going 50 MPH and it began to sputter and reduced speed to 20 MPH. Very dangerous situation, but I pulled off on side of road. When tow arrived driver got in car and the gas needle moved back up to almost qtr tank and no low fuel lights or warning sound was generated, engine turned over but it would not start. Had it towed to gas station and put gas in it, still would not start. It was not out of gas. The reading was incorrect. Towed to dealership and they still have not found the problem over a week later. Stated it could be an electrical problem. Electrical service repair tech is checking it. I have seen similar scenarios reported on this site. GMC/Chevrolet needs to do a recall. This is a dangerous situation. Luckily I wasn't on a very busy road.

When I put my 2018 Chevy Malibu in Park i receive Shift to Park' error message. I have to keep pushing on the gear shift to get it to go into park mode. It happens frequently. I have seen numerous reports of this same problem. The last time it happened was around 9/19/22, but it has occurred since I purchased the car in 2019. It began when the car only had around 40,000. There should be a recall from GMC/Chevrolet.

The contact owns a 2018 Chevrolet Malibu. The contact stated while driving approximately 55 MPH, the vehicle shifted into Limp Mode. The contact stated that she pulled over and when the gear was shifted to park (P), the brake vacuum pump failed. No warning light was illuminated. The vehicle was then towed to her residence. The contact stated that an independent mechanic went to her residence and diagnosed the vehicle. The independent mechanic retrieved DTC: P0365 for the camshaft position sensor. Additionally, the contact was informed that shattered pieces of the brake vacuum pump dispersed into the camshaft. The contact stated that pieces were also found in the oil lines. The contact stated that the brake vacuum pump was repaired; however, the camshaft sensor was not yet replaced due to the part not being available. The manufacturer was not made aware of the failure. The approximate failure mileage was 83,000.

When I shift the car into park the dashboard gives me a message that the car needs to be shifted into park. This is an intermittent problem and does not occur every time I shift to park. When I get this message I am not sure if the vehicle is actually in park. The problem has been diagnosed by the dealership. The defective part has been replaced by the dealership. The only message I received is the one on the dash stating to "shift to park".

Malibu would not recognize shift into park. This happened multiple intermittent times. Had to take it to dealership to be repaired on 9/6/22. While waiting for my Malibu to be repaired I was talking with a gentleman who had his Malibu in for the SAME problem. He stated his friend had the same thing happen on his Malibu. I came home and looked up information on this problem and found it isn't just Malibu's and I learned that there is litigation about this problem in Michigan. Why has there not been a recall for this problem?

I was driving 35 mph when the message "reduced engine power" and it noticably slowed down. The check engine light is still on. I researched recalls/problems with the 2018 Chevy Malibu and this is one major one I found.

The contact owns a 2018 Chevrolet Malibu. The contact stated that while attempting to park the vehicle, the "Shift to Park" message appeared on the instrument panel. The contact was unable to turn off the vehicle. The contact attempted multiple maneuvers to turn off the vehicle and was eventually successful. The dealer was notified of the failure and an appointment was scheduled for service. The manufacturer was also notified of the failure and referred her to the NHTSA Hotline for assistance. The vehicle was repaired. The failure mileage was approximately 25,000.

Shift to park light comes on when it was already put in park and shut car off.

8 months ago brakes failed, you could stop but they were hard and stretched stopping distance, vacuum pump failure was the cause, when it failed it broke apart and sent parts into the engine, (valve cover ). Replaced vacuum pump removed valve cover and fished out the broken pieces, was lucky on this occasion, fast forward 8 months later , the mother of my kids was on freeway and car completely died,, got it to dealer and was informed, vacuum pump failed again sending metal fragments into the valve cover but this time pieces destroyed the cam and caused the reluctor to slip thus causing ecm to shut down engine. I’m concerned with there not being some sort of housing inside the valve cover cupping the side of cam that meets vacuum pump to shield engine components from metal pieces incase vac pump broke into pieces since vacuum pump isn’t part of the engine itself and the torque of cam shaft up against the gear on vac pump is very high, the expectation of parts braking off is highly likely, and there nothing protecting your engine from those fragments.. I’m not the smartest but I would not think a $100 external part could destroy and engine and take your braking function without any warning. I guess if I happen once I wouldn’t think to much into it but for the third time and being extreamly lucky on the first two occasions and taking responsibility for repairs are totally uncalled for , so now I have to replace and engine, WOW... I hope this can be addressed before someone actually gets hurt, I’m so lucky that my kids mother was able to coast off the highway b/c it could have been bad..

I was leaving the gas station and when I got ready to pull off into traffic the car stalled. Flashed a message saying the automatic steering was disabled or something drive with care. I go out this morning and it won't start at all. It cranks but won't turn.

When I come to a complete stop and take back off, my car flashes a warning " steering assist reduced. Drive with care" this just started 4 days ago. Within those 4 days, every time it starts back up all lights flash on then back off. My check engine light has not gone back off since 1 day ago. I have done research and I have realized that this is a common problem for this make and model car. Most complaints regard power steering control. I'm wondering what can be done, because there has not yet been a recall for this issue and it is a complete safety hazard, especially with children in the car. I would hate for any lawsuits to come from something that could have been avoided.

The contact owns a 2018 Chevrolet Malibu. The contact stated that the driver’s side air bag in the steering wheel had fractured near the lower part of the steering wheel. The contact contacted the dealer and was referred to the manufacturer with assistance to have the air bag replaced. The manufacturer was made aware of the failure and informed the contact that the repair was not covered under warranty or recall. A case was filed. The approximate failure mileage was 63,250.

Something draining my battery done put a new battery in it no lights or anything on when I get out been going on for bout 3 months now

When going to shut off the vehicle the display comes on "shift to park" and will not allow the engine to shut down. Must turn car back on, place into a gear, place into park and turn off power again. This has occurred multiple times over the past few days. It will also take 3 or 4 cycles to finally get the car to shut down completely.

My Malibu makes a knocking sound in the rear of vehicle. Feel like something is going to snap off, also driving on reverse sound really bad, check my trunk if something was loose and nothing.

When I get to a destination and put car in park it says " shift to park" like it's not in park. I have to wiggle my gear shift around for it to go away. Or when I park, I have to give it a forceful push to park.

The contact owns a 2018 Chevrolet Malibu. The contact stated that while driving at 70 MPH, the brake pedal depressed and it traveled to the floorboard as the vehicle failed to stop without warning.
