I was driving 35 to 40 mph before vehicle slowed to almost a stop and when pressed gas pedal it excel slowly creeped to less than 30 MPH THANKFUL I wasn't rear-ended.Pulled into nearest Autozone part store and diagnostic scan showed the P2138 code. DC severity, sensor, and accelerator pedal position - see photos attached. Waited with engine off for approx over 30 minutes then started vehicle, engine lght off and proceeded to my destination excell with no issues.This has happened several times since purchase of vehicle began 2019. Throttle body repairs, ECM replacements and harness repairs later still reoccurring documented at dealships and repair shops. This is a serious and costly hazard.

Vacuum pump failure. Brakes failed while driving the car, brakes became manual power but was able to pull over safely. There was no previous warning or error codes. Car is currently at a Mr. Tire facility. The manager ran diagnostic code - "reduce engine power" error and found the cause as the vacuum pump. Due to the time of the failure, late Saturday 9/14/24, the part cannot be ordered until Monday from the local Chevy dealership. The facility will not know if there is additional engine damage until the part is remove and inspected. There is known issues with vacuum pumps failing and a class action lawsuit currently in ligation.

The car will not turn off when placed in the park position. A warning comes on that states "shift to park" when the car is already in park. I have contacted Chevrolet twice and was notified that their are no open recalls on this. This is a very common and known problem with 2016-2019 Chevy malibu as well as Chevy Cruze model. Chevrolet is no help in this matter. I feel this is a large safety issue as you cannot turn the car off. PLEASE HELP!

The main head gasket fails on these vehicles causing oil to leak everywhere and on top of electrical wires. The lost of oil has caused the engine to reduce the engine speed randomly on the highway which had risk of accidents multiple times, by unable to move the vehicle off the road at a reasonable time. The oil sips land on top of electrical wires which creates the risk of fire.

Vehicle check Engine light on, showing "Reduced Engine Power." Vehicle still able to be driven, but will not accelerate with any proper pace or power. Cannot get above 3000 RPM without losing power, has put me in two dangerous situations in the last two days that almost made me lose my life. On highway, trying to accelerate to match traffic speeds, lose power and had to dive to the emergency lane to not get plowed by a truck. Today, was city driving, at a red light, could not accelerate and had to dive to a crawl the vehicle into a turn lane where I ended up sitting for about 10 minutes till the engine offered enough power to keep driving. By all information I can find online, it seems it is similar to the issues presented by others online and might tie into "Special Coverage N182188250 Loss of Continuity within Accelerator Pedal Position Sensor Circuit" that I found here: [XXX], this issue has been going for about 3 weeks to a month and is only getting worse. I did stop at McCarthy Chevrolet of Overland Park to have codes run about on [XXX], the codes showing do not show in the above link...codes: U1502, U0422, P06DE, C0760...those all present on the paper as "Current." I have not had it diagnosed yet, planning to, service is just so expensive. I have had the car in my car for 1 year and 1 month, purchased from MAX Motors in Harrisonville, Mo. Reporting here as I also saw online that others are facing the same symptoms, and that there is a suit that might be addressing these issues: [XXX] Every time the car is turned on, the warning mentioned above shows. See picture attached. Does not matter what type of driving or set "speed limit" issues show. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My car was started shaking really bad and the stabili trak sensor came on. My engine had to be replaced in February 2023. My car was at 66K miles. I rarely drove it. I worked from home for 3 years due to the pandemic. I purchased the car with about 12K miles. I was on my way home and my car just shut off. I could not get it to start at all. The stabili trak light came on. This was in January 2024 with 75K miles. The tow truck driver told me he had picked up multiple Chevrolets experiencing this same issue. It took the dealership almost two months to figure out that the crank sensor needed to be replaced.

Vehicle engine light reported codes P050F, FE8:engine, and FE9. It was determined the Brake Booster Vacuum Pump was leaking oil and was faulty. It has been replaced and brakes better. Engine light went off. The other diagnostic by my mechanic showed the Oil Control Intake and Exhaust Variable Valve Timing (VVT) Solenoid needed to be replaced too.

I am very upset right because I purchased this Chevy Malibu 2016 from Vroom. It was fine at first and then things start to go downhill. For starters my tire light came on first only a week after having the car, then the shift into was appearing on the dashboard as well as the engine light. Then my husband spent almost 2000 on the brakes because the car was making this horrible sound and I almost couldn't stop the car because the pedal was stuck and would not push down. Thank God no one was hurt. Then my car just shut off twice one day at a busy intersection, it went completely dead with my children in the car. This is a ongoing issue. Now I had a diagnostic test ran on my vehicle and it was said I needed a new motor only after having the car for only a year. This car is very dangerous and I wish they would take it off the market, because it will also reduce your speed while driving out of nowhere. Chevrolet should be responsible for all problems before they are aware of these issues!

My car enters a reduced engine power mode causing my car to slow down during high speeds with a potential acciden-??. the Malfunction Indicator Light (Check Engine Light) will illuminate, the -??Engine Power is Reduced-?? message will display. I have called GM and was told it wouldn't be covered, I have talked to the dealer and taken it in before but I can't afford to keep paying a $150 fee to have my car looked at. I have been having this issue since April

I was driving about 70mph on a highway trying to pass a semi-truck. As I signaled right blinker to merge back into the right lane, the speed reduced to 40mph without notice. I then seen a notification on the dashboard saying "Engine Power Reduced". The car would not accelerate fast enough to clear the truck therefore almost causing a collision of 2 semi-trucks and myself. I was forced to drive off road to help avoid the collision. My fiancé was in the passenger seat when this happened on 11/25/2023. He then began telling me this happened to him a few months prior but he didn't mention it because it resolved itself. This was actually the 3rd time it had happened in this car over the last 2 years. I spoke to the chevy dealership about it the first time I experienced this and they advised that it had not been made a safety recall at that time yet, but the technician who helped me said his son experienced the same thing and it was becoming quite common. It still has not been recalled but there is currently a class action lawsuit because of this. I feel this is very dangerous and what I considered to be reliable transportation, is no longer the case for my family after this experience. This needs to be recalled immediately before people lose lives. Especially since the parts were Manufactured incorrectly and Chevrolet had knowledge prior to releasing 2016-2018 vehicles.

Bulletin 19-NA-122 that General Motors posted about my specific car having future engine issues happened to my car right after their mile limitation. They said due to my miles being pass the number and although I-??m with in the 10 year window they cannot do anything for my car. I was driving in the high way using cruise control then my car just randomly slowed down on the highway, my stabilitrack sign came on and my check engine sign started to blink and my engine started to shake my car. Very dangerous and I was not notified about these issues a single time I took my car to the dealership when it was within the time frame.
