2018 Chevrolet Malibu complaints

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.

The contact owns a 2018 Chevrolet Malibu. The contact stated that the check engine warning light was illuminated and flashing. While in the park position, the shift to park message was displayed. The vehicle was slow to move. While adding fuel to the tank, the fuel would bubble at the top and stop. While driving approximately 35 mph, a 2018 GMC Terrain crashed into the front end of the vehicle. The driver sustained injuries to her hip, soft tissue, lower back, whiplash, and neck and medical attention was provided. There was a police report filed. There was no reported fire or air bag deployment. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The approximate failure mileage was 20,000.

I got P2138 code, i replaced the accelerator pedal on my cost because the dealer told me my car VIN is not include in the recall, the code keep coming back even after replacing the pedal. The problem it happen two time were I was driving on thruway "65 mph" the speed suddenly reduced to less than 30 mph which put me and the other drivers safety in dangerous situation

The contact called on behalf of his daughter who owns a 2018 Chevrolet Malibu. The contact stated that his daughter informed him that she had noticed moisture on the inside of the windows and the front and rear windshields. Additionally, the contact stated that the third brake light was not properly secured in place. The vehicle was taken to the dealer where it was diagnosed that the third brake light needed to be replaced. The contact also stated that there was water leaking into the trunk. The contact stated that upon investigating the cause of the failure, he determined that the water leak might have originated from the third brake light. The contact stated that the failure had caused mold to develop inside the vehicle. The contact related the failure to GM Technical Service Bulletin Numbers: 20-NA-126 (Water Leak in Rear Compartment) and PIC5822E (Water on Front Floor and/or Carpet). The dealer informed the contact that the owner was responsible for the cost of the repair. The manufacturer was notified of the failure but provided no assistance. The failure mileage was approximately 54,000.

Suddenly loss of power at cruising speeds. Trouble with acceleration and loss of power. Unresponsiveness from the engine. The Check Engine Light illuminate, OBD2 call for code P2138. The speed stuck at 30 m/h on the 65 m/h thruway which cause unsafe situation for me and other drivers on the road. When googling this issue on the internet, reviews show it is common problem in this model. GM refuses to fix this issue at their cost because "according to the VIN number of my car, it is not included in the recall list" which it does not make sense.

On Nov. 18th 2022 while driving on county Rd at 55mph I slowed to make a left turn. As I went to accelerate at about 30mph the vehicle lost power, I pulled over shut off the vehicle. I started the vehicle and the engine symbol appeared, I continued to drive, I had power so I entered the interstate. About 2 min. of driving The vehicle went from 70mph to 40mph. I pulled into a dealership to see if I could get the vehicle looked at. They said they were booked up that it would be about ten days. I continued to my destination there were no other issues beside the engine light staying on. At a half tank of gas I filled up, when I went to leave the The engine light was off. No other issues since.

Was driving to work when suddenly my check engine light comes on and I get a warning reading “reduce power to engine” could feel the power literally reduce. Car won’t go pass 30MPH could hear the engine trying to accelerate but struggling too. This is the second time it happens, have noticed other complain about this on going issue with 2016-2018 models

I keep getting a reoccurring message saying Engine Speed reduced, I can be driving going 60+MPH and randomly My car speed is reduced. This is becoming a safety issue as i have noticed this is a ongoing issue wit the 2016-2018 Chevy Malibu's.

The contact owns a 2018 Chevrolet Malibu. The contact stated while the vehicle was in a park, he noticed that a warning light indicating that the vehicle was not in park was illuminated. The contact also stated that while driving at an undisclosed speed, he heard a knocking noise at the rear-end of the vehicle. The vehicle was taken to the dealer where it was diagnosed that the shifter cable needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 21,000. The VIN was not included.

Please see General Motors Technical Service Bulletin 19NA206.745.57. There is a problem that occurs with the transmission shifter. Even though the driver has shifted into Park, the switch inside the shifter assembly triggers a message "Shift to Park." At times, the ignition cannot be turned off and the driver has to keep trying. My Malibu was affected by this issue.

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 mul

Brake Power Booster, vehicle not starting. Not catching, brakes when completely out couldn’t stop

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".

Engine reduced while driving

The steering wheel is jerking when in the position to turn, and waiting at a light. The STOP ENGINE Feature seems to make the jerk motion and also sends an ALERT MESSAGE which is a quick flash STATING "Steering Assist is REDUCED- Drive with Care". According to a SERVICE BULLETIN Provided by GM BULLETIN #19-NA-182 AUGUST 2019. This is a problem that needs to be corrected, for the safety of my family and others in the vehicle and on the road. Next, the car shut off and the command center went blank,

I am the first owner of a 2018 Chevy Malibu. This car was displayed on the showroom floor. Shortly after purchasing this vehicle a new “computer” was needed. Following the new computer, my Chevy Malibu would be at approximately 70MPH and would “engine lock” its speed causing it to suddenly go from 70MPH to 20MPH while on a freeway. During this time my Chevy Malibu would reeve at approximately 5,000 RPMS and would not go over 20MPH. I brought this to GMs attention and they appeared to have very little concern. As a mother of two and a Police Officer I was very upset with GM. My vehicle has “engine locked” itself multiple times and has been towed to a dealership. Fast forward, my car, will not turn off and I’m unsure if it is going into “park”. I have replaced the “wire harness” or “transition switch” where my shifter is located. It has been approximately two months since replacing this part. My Chevy Malibu is once again not going into park and will not turn off. I am concerned my car will roll away while I am at work or out in town and cause serious injuries. GM does not seem to care about these issues. Issues being, the “shift to park” and the “limp mode” issues that my car continues to have. As a Police Officer I know that this could be VERY dangerous and I would like a solution to this issue or a new vehicle. This vehicle is not safe.

As I was driving I was addressed with a speed reduction warning and it followed with a very abrupt problem with speed as it was reduced drastically and almost getting rear-ended in the process I was able to pull over but very unsafely and without warning

Shifter sometimes does not recognize it was put in park. Trouble getting it to recognize park and turn off electronics. Class action law suite may be in the process with multiple models. Happened multiple times and more frequently.

What component or system failed or malfunctioned, and is it available for inspection upon request? A defect in the cam shaft solenoids causes a notice that "Engine Power is Reduced." At that point, the engine begins to struggle to accelerate from a stop, and from increasing speed while on the highway. How was your safety or the safety of others put at risk? The unpredictability of the defect and its affect while driving poses a large threat to safety, particularly on the highway. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The dealership service rep not only confirmed the defect, but also confirmed that the issue persists across multiple GM models yet no recall exists. Again, this is a KNOWN defect with GM engines, as confirmed directly by the dealership. Despite this, no remedy was offered, I was told it's neither covered by my manufacturer's warranty or recall. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes. I was given a video explanation of the issue and also told directly of these persistence of the defect across multiple lines. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warning prior to the failure. The defect and "Engine Power Reduced" message both first presented in March of 2022, less than a year into my ownership of the car -- and while my car was still under its 60,0

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.

12/27/2021 I started my car to leave work & noticed a loud tap. I've worked for dealerships in the past & was part owner of my own repair shop for many years. Popped the hood, checked the oil level which was good, & figured I'd be fine to drive it home to park it & then hook the scanner up. Mid-way home I received an engine performance notification on my dash, but other than that it seemed safe with no diminished speed. Less than 3 miles from home I went to stop at a red light & had the hardest brake pedal I've ever felt in my life. I was fortunate nobody was around me so I put all the weight of my body on the pedal to stop the car at the light. The engine was sputtering & the steering felt tight & it felt like it was stalling, with a green turn arrow I risked crossing the highway & was able to safely park in the community's rec center. I'm not one who is quick to take anything to the dealership because many times the techs are lazy, so I hit the web & found two things. One - there is an extended warranty on the TPS sensor which is the entire gas pedal itself. This could explain the engine performance notification, but not the lack of brakes. Upon hours & hours of additional reading I found the problem - the vacuum brake pump. We ordered it & replaced it but I can tell you my engine likely needs an additional camshaft replacement for it to ever be right again. Two codes remain: P0014 & P0017 - Exhaust camshaft/crankshaft position not plausible. What was the condition of the v

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 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

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

The contact owns a 2018 Chevrolet Malibu. The contact stated while driving approximately 65 MPH, the vehicle stalled, causing the power steering and power brake functionality to become inoperable. The contact stated he was unsure if any warning lights were illuminated. The contact had managed to coast off to the side of the roadway. The contact stated that several attempts were needed to restart the vehicle and he was able to drive the vehicle to his destination. The contact stated that the failure started off as an intermittent failure, but gradually had become a constant failure. The contact stated that the failure recurred and the vehicle had to be towed. The contact had taken the vehicle to a local dealer on several occasions to be diagnosed; however, the mechanic was unable to duplicate the failure. Additionally, the contact stated that the radio would randomly switch through the preselected stations. The vehicle was not repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 75.

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).

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.

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.

My car constantly gives an error saying the power is being reduced to the engine. It was repair 3 months after I bought it but it didn't fix the issue. These cars a danger to everyone around us. They reduce speeds to very low numbers even on the freeway, when yielding to turn left the car won't go but will drift into oncoming traffic, and many times the car won't shut off. It says it's not in park but it is. The seatbelts look like they're secured but with one good tug they'll come apart. And I slide when braking even without snow or rain. Mine I'd always broke down and no one will help me. I pay 475 a month for a car that doesn't work and is dangerous to me and my special needs child and everyone around us. Please do something.

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.

The stability track system comes on the vehicle slows down and stops in traffic. Then it says shift to park and will not start. The computer often displays reduce engine power.

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.

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.

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?

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

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.

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.

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 actua

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.

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.

The contact owns a 2018 Chevrolet Malibu. The contact stated the vehicle's reduce engine warning light would illuminate at various speeds. The contact would pull over unlock then lock the vehicle in order for the vehicle's warning light to no longer illuminate and to regain proper function. While driving 75 mph when the engine warning light stating reduced speed illuminated. The mph dropped to about 25 mph. The vehicle's OnStar displayed a message stating that the antilock brake system was detected and the vehicle powered off shortly after. The vehicle was towed to a certified mechanic who diagnosed that the crankshaft needed to be replaced. The vehicle had not been repaired. The manufacturer was made aware of the failure and informed the contact that their vehicle was not included in any recall. The failure mileage was unknown.

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. After the failure occurred, the contact stated that the vehicle failed to restart upon parking the vehicle. Due to the failure, the vehicle was towed to a dealer where they discovered that both the vacuum pump and camshaft sensor were defective and needed to be replaced. The manufacturer was notified about the failure and referred the contact to the NHTSA Hotline. The vehicle had yet to be repaired. The failure mileage was 79,000.

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.

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 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.

Most the time I park now, the vehicle does NOT recognize when I shift the vehicle into PARK. The transmission control (the "stick") is positioned correctly, but the vehicle chimes and warns vehicle cannot be turned off until vehicle is in PARK regardless. I am not sure if the vehicle is literally not in PARK, or if the vehicle's system sensors simply are NOT functioning correctly. Usually some jiggling of the stick causes the car to eventually recognize the PARK is engaged, but it is never certain. So far this issue has mostly resulted in inconvenience and annoyance, so no police reports or mechanic investigations yet. But whatever the nature of this malfunctioning PARK, under the right circumstances, this issue could conceivably lead to accidents and deaths if not addressed and repaired soon. I am reminded of Anton Yelchin's SUV crushing him to death after he thought his vehicle was in PARK but the system wasn't working correctly. My vehicle is 4 years old now and this problem only began manifesting recently, perhaps 3-6 months ago. I have searched online and I have found at least two other owners of this same make and model and year have experienced the exact same problem. I suspect this issue could lead to catastrophic problems in the future if not fixed early. Please investigate before things get out of hand.

I shift my car into park and try to turn off the car, the car stays on and tells me to shift the car to park even though it is already in park. Car is having continuous transmission and emission issues that cannot be resolved by the Chevrolet dealership, resulting in paying lots of money and the engine light and emails from OnStar still appear.

On 3 occasions, my vehicle has displayed the message “Engine Power is Reduced.” It has 83, 990 miles. I took it to the dealership to have them check it out, but I was told they couldn’t check it because the check engine light was no longer on. This is a problem because the warning will come on, then the check engine light turns off after the car has been turn off. The Chevy dealership says there is a three day wait for them to conduct a diagnostic, but what are the chances the check engine light will remain on? After having gone through this process on three separate occasions, the check engine light hasn’t appeared the next day. I have read about how others may be experiencing this problem and they do not have some resolution to this kind of problem. My wife generally drives this car, so I fear for her as she travels to and from work.

While im driving the stabilitrack warning will pop on then the engine light & immediately after my car will jerk to a almost stop. Then when I try to press on the gas peddle it will go slow but my peddle power goes to a 4. The dealership said it was my tire speed sensors so I got them replaced all to STILL have the same problem. It will also read power stirring not available & shift to park even tho I’m already in park.
