While driving my check engine light comes on and then I have a warning come on my screen on the dashboard that my car is shutting down power. So while I’m driving, at any point in time my car shuts down the power and I have to quickly pull over wherever I am so that I do t get into an accident Then shut my car off and wait a little bit and then turn it back on and keep driving. I looked into my car and my car was part of a recall in 2019. Supposedly the recall was completed BUT my car is doing the exact same thing again with the ECM that was supposed to be fixed.

Bulb - Third Brake Light Assembly: replace the third brake lamp asm. its broken. Common issue with Chevy malibus 2016-2018. The bulb in the back of the rear window which is an added indicator that the vehicle is braking. Cars are almost crashing my car when i break to turn. I have a young son in the car and this is dangerous especially if this is a common issue amount chevy malibu drivers. There is a GM forum where numerous people are complaining about being given $400-$700 repair estimates when it should be a recall from the manufacturer.

Saturday morning this is now the 3rd time it's been fixed and safe to drive. Once by the dealership in Baltimore Towson area. Check engine light came on I ran diagnostic I bought at the store to get the codes come to find out class actions for wrongful death because company knew about it. As I also see hundreds of he same complaints here. My wife on [XXX] Baltimore MD at the merge. She went from 60mph to 35mph. Then the car shut off with zero control of steering. Once in neutral she slightly touch the brakes which let it start up. Thank God no one was killed we have 2 beautiful 6 n 7 yr old girls what would I tell them. This needs addressed it happens after the batt needs changed I know 4 other owners 1 had just got one that's what triggered his same codes problems. Im I've Googled it but not one person solves it. It's gotta do w the start stop system INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving down the highway and took the exit and went to hit the brake pedal and it was hard to push down. Took it into a shop for diagnosis/repair. Mechanic found that vacuum pump for brakes came apart. There is currently metal in the engine that I cannot afford to fix after already paying $500 for the new vacuum pump.

I was driving my small child to school and my car had a service message pop up that said engine power reduced and then my brake pedal became stiff to the point where I could not push it down at all to stop at a red light. Luckily by quick thinking I push down my emergency brake to avoid from hitting other cars. From doing research this is not the only complaint about this same similar situation on this car (2018 Chevy Malibu LS) It's ridiculous. It's going to cost me over $2000 for parts and for labor.

Engine Power Reduced Defect in Chevy Malibu Vehicles. Had the "engine power reduced" message show up countless times.

I put the car in park and got a message shift to park. I then wasn’t able to shut my car off. The car is only 6 years old! This should not be happening!!!

On Jan 22,2024 while driving on the interstate the speed was unexpectedly instantly reduced, the car would not accelerate over 60 mph and the service engine light came on, the car was safely driven off the highway then towed to the dealership. My safety as well as the safety of other drivers on the highway was at risk when the car suddenly decreased to 60 mph from 75 mph which could have caused a collision. The inspection at the dealership confirmed that the issue was the intercooler for turbo found moisture/oil frozen in charge air cooler causing restriction in induction system, and the part design has been updated to help prevent the issue from happening again. My issue is that if the part has been updated that means that GM is aware of the issue and should be responsible for the cost of the part or there should have been a recall on the part. The consumer should not have to be responsible for the cost of the part or the repair to the vehicle. It is unknown if the part was inspected by an insurance representative but it was inspected by the dealership where the car was purchased. There were no prior warnings, lights or lamps occurring before the date of the incident. I feel like Gm should cover the cost of the repair, the total cost should no fall on the consumer and the vehicle manufacturer should take responsibility for the defective part.

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

The car's Reduced Engine Power light comes on and the engine drops power. It just happens at any time while driving. I've had oil changes done, engine cleanings done but nothing changes.

The Vehicle wobbled when at 70 MPH. I have new tires but the wobble won't stop. I have visited a mechanical specialist was refer to this site. Also, the Radio Display touch screen is not working.

While driving on highway, check engine light came on as well as message saying "Engine power reduced". Car immediately decelerated on the highway and brakes pedal became rock hard and unable to press.

I was driving my car and my entire car’s dashboard went out and the cars speed dropped I tried braking but they kept slipping. It was a very scary event for me as I was driving on highway 59 when this happened to me. The TCM is s a problem for this vehicle please recall this issue.

I have an ongoing issue with the shifter not communicating to the ECU that it is in park. I put the car into park, dash board shows in P (park) and transmission is in park (ie won't move forward with brake released) and when I go to turn the car off I get message that car is not in Park. To remedy this I have to smack the back of the shifter forward sometimes 5-15 times and from light to moderately hard pressure to get the ECU/sensor to realize it's in Park. The shifter was replaced by a Chevy dealer 2-3 years ago but the problem started again. I believe there needs to be a recall due to the same issue ongoing [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Transmission Surge Accumulator System Performance. The car fails to accelerate once it comes to a complete stop, traffic lights, etc. The car will rev up to 5000 RPMs but will not reach 10 mph. This causes problems when driving and I was almost hit on several occasions (more than 8 times) on my drive home to be safe again. The car was taken to the dealership and was reported to have been fixed, after paying a $100 deductible, but only ran properly for one day. Again, I was almost hit 5 times while driving back home, after the repair was made. The check engine light came on after the car presented issues, as I was out running errands, the car was losing power and was not performing well. About 20 minutes after the initial issue, the check engine light came on. I took the car to Auto Zone where they were able to run the diagnostic that came back with the code, P171D Transmission Surge Accumulator System Performance. This took place twice in one week, with the dealership fixing the issue on Tuesday and it failing again on Saturday (after the car sat idle for 3 days, while I was on vacation).

The vehicle was randomly shut down. After waiting, the vehicle restarted. While depressing the brake pedal, there was an abnormal, unidentifiable noise detected, and the vehicle came to a sudden halt. While driving at 55 mph, the vehicle suddenly stopped, and she hit her head on the steering wheel but medical attention was not provided. The vehicle was pulsating while driving. There was a sound of water going through the vehicle. The vehicle was slow to accelerate and then moved violently. All the instrument warning lights were illuminated. The vehicle was taken to the local dealer, who was unable to duplicate the failure. The vehicle was not diagnosed or reported. The vehicle was taken to another dealer, Capital Chevrolet, at 9820 Capital Blvd., Wake Forest, NC 27587, where it was diagnosed that the vehicle was not safe to be on the road. The oil throttle body and vacuum pump needed to be replaced. The vehicle was not repaired.

My car will stall in the middle of driving will say it is not in drive, the power steering is reduced, and I cannot use the brakes properly. This is a safety issue. As I drive on interstates and highways on my commutes.

Mass air flow sensor has been replaced 3 times. Keeps going bad causing hiccups and hesitation. Very dangerous at times

Service Stabilitrak warning will pop up on my dash. The car loses power. Push on the gas and it sputters. Had it serviced by GMC 2 years ago and now it is happening again. More frequent in colder weather. There are thousands of reddit posts about this same issue from other 2018 Chevy Malibu owners. GMC refuses to acknowledge it is a quality or performance issue on their end.

While driving, my car’s dash suddenly showed a warning message that state “engine power reduced”. I was driving around 45mph at the time of the incident.

I was driving the vehicle on a busy road and a message came up on the display above the steering column saying Engine Power Reduced. I went to brake and was unable to push the pedal in as it was extremely stiff. There were vehicles around me and I tried to use both feet and stand on the brakes and was able to get a little bit of movement but the car still didn't slow down. I had my significant other and brother-in-law in the car and we were all horrified we were going to get into an accident. I turned the hazard lights on and was able to steer to avoid hitting several vehicles and when traffic finally cleared I was able to get over and off the road into a gas station that was uphill and allowed us to slow down and finally stop because I put the vehicle in neutral tried the parking brake which got us to a complete stop and shut the vehicle off. There had been no previous issues with the brakes or messages such as the one that came up right before this issue occurred. The vehicle had to be towed and the repair shop told me the cam driven vacuum pump failed which caused the brake booster to not function. When this failure occurred, it damaged the intake and exhaust camshafts, crankshaft, and several other components. The cooling system and oil to be flushed out as I was told there was metal debris from the damaged parts caused by the vacuum pump failure in the fluids which had been all completely flushed and changed including cooling system, transmission fluid, and oil change Th

Engine power reduced

My turbo failed while I was on a very busy highway, causing me from going 70mph to 35mph in a matter of seconds and almost being hit. This put my life and my friends life at risk since we were in the left lane. Now that I’ve been fighting with the dealership ti help make this right they found a GM warranty that fixed and updated electrical sensors. We fixed that first because at the time we thought that was what it was. My turbo gave out again up in the mountains almost killing me and my friend a second time on a busy road. We made it to a parking lot and called a tow truck. Now the stabiltrak is showing up and the car refuses to start, it makes a whooshing sound and doesn’t start completely. (There is fuel, oil, etc). I was sold an unsafe vehicle and now I’m stuck paying 500$ a month for a car that’s unsafe and refuses to work even when it’s been fixed. The dealership is refusing to help me, I’m at a loss. I still owe 18k and I can’t have an in working car sitting in my apartment complex, it will get towed and cost me more money.. I need help. I was sold a car that almost killed me twice and no one seems to care.
