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.

On may 23,2024 I was on a very busy highway going 66. All of a sudden my 2016 malibu lt aburtely slowed to 27 miles an hour and two warnings lights came on 1 -engine power is reduced 2 - speed reduced to 27 I barely avoided getting hit by two semi trucks, as well as a car. The car is available for inspection on request. An independent service person confirmed it was indeed a defective electron control and acceleration peddle position sensor. How very irresponsible of you not to put out a recall on the 2016-2018 models knowing very well of the many class action law suits that have arrived from this issue. I probably can guarantee none of you own a Malibu. How very incredious it is that you put people lives in danger knowing that there was issues with the problem. Unbelievable. I almost got killed because of the lack of responsibility because you dint make a recall.

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)

*Accelerator Pedal Position Sensor- It is available upon request. * Due to the malfunction of the accelerator Pedal Position Sensor, the check engine light comes on and it flashes "engine reduced power" which slows the car down to a very low rate of speed not allowing the driver to go any faster. I was on the highway going speeds of around 75mph and that light came on and slowed my vehicle down which caused the car behind me to almost run into the back of my vehicle. I've had this occurrence with this problem several times. * UNKNOWN *UNKNOWN, absolutely nothing prior to the check engine light and "engine reduced power". The issue is sporadic and happens at any given moment. There is no warning that alerts when this happens.

I was driving down the interstate when all of a sudden my information center on my was driving down the interstate when all of a sudden my information center on my 2016 Chevy Malibu popped up a warning, reduced engine power and drop me down to 20 mph without warning. I barely made it to the side of the road before being run over by 18 wheelers all around me. Once I got it home I read the code, and it shows there-??s not enough power going to the turbo in the engine that-??s caused by the accelerator sensor. When I start at low speed or from a stop in attempt to accelerate the car hesitates to the point I can-??t pull out with any cars around because I will be hit. I-??ve been told this is a known problem for the vehicle and it-??s a $500 part to fix. It-??s extremely dangerous and I am so shocked there has not been a recall for this, it is putting everybody that is in one of these vehicles in danger

I took my car to to Firestone to have the brakes checked because I had a stiff brake pedal and could only use my emergency brake to stop. They did a basic and advanced diagnostic and said that the brake booster that I have has been recalled and also other equipments on my car has been recalled and I must bring it to a dealership. I searched my VIN and nothing popped up even though months ago I was emailed a recall notice on the fuel pump system and Air bags and it has never been repaired in my car even from the past owners.There have been 10 recalls from Malibu's manufactured in 2016 and my car shows every sign and indication that it is one of those few selected. My VIN should be updated or investigated for parts in my vehicle that have been recalled. The Car stops when idle for two minutes or longer and shuts off the engine and air if you use the USB outlet there is a serious electrical problem which is also a safety hazard according to NHTSA guidelines.

I just bought this car 2 weeks ago. Had to replace the windshield wiper pump. There are at least 10 TSBs on the vehicle I'm on disability I can't afford to fix all that. The rear hub bearing was barely making noise when I bought it. Now tire feels like it's going to fall off. I believe there's a TSB on when you put the car in park and shut it off then it's not going in to gear even though it said it's into gear so I have to get that fixed as well. Can't Chevy fix thermostats just like I have to fix my mistakes in life.

#1 3rd brake light leaking into back seat and trunk manufacture bolts backed out and/or missing, can also cause water to get into the brake light which tends to cause 3rd brake light failure, increasing risk of a crash. #2 gear shift lever inner lock blocking the ability for user to shut the vehicle off, this can also cause the gear shift lever to indicate vehicle is in park, but the transmission may actually be in another gear. This can lead to damage to the transmission or increase the risk of a crash. A recall has been made for Chevy Malibu 2016-2020 but my VIN was not included. While my vehicle is experiencing these issues. Issue was confirmed by an independent service center. Shift to park message pop up on dash when attempting to shut vehicle off unsure of exact start date but started a few months ago. I have since been doing my research on issues and their solutions.

When the vehicle is shifted (manual transmission) from any gear into park, and the vehicle is turned off, the "Shift into Park" warning appears. I verified it was in the park. Warning stays on from 1-5 minutes, leaving all outside marker and headlights on until the sensor engages and the vehicle returns to proper state (outside marker and headlights shut off and interior dome light turns on for exiting the vehicle. This occurs each time the vehicle is driven, and the malfunction has caused a reduced battery power (eventually replacement) and outside light replacement from unnecessary use. Losing battery power has left us stranded, and the loss of outside lighting reduces our visibility for other drivers to see the vehicle. Upon research, this has been reported and reproduced numerous times to the manufacturer, dealers, and NHTSA with no solutions reached except charging the customer to repair the issue (this is unacceptable). There were no warnings and the symptoms started approximately 2-3 years after purchased in 2016 and still continue (brand new car).

My gears sometimes will be stuck in park.

Intermittent "Shift to Park" message started to show up when attempting to turn off vehicle. GM does have a special bulletin 19-NA-206 but doesn't have the coverage stated in it. There is also class action law suits as well so this is a common concern.

My 2016 Chevrolet malibu is displaying a "shift to park" message for the second time. We had the Automatic Transmission Control (GM part# 84347430) replaced two separate times already costing us over $1600 in repairs. Also had to replace 2 batteries within the past 3 years which cost over $300. First replaced in March of 2020 and now again in Feb 2023. Current lawsuits for this problem are on-going. No loaner cars were given for these repairs resulting in inconvenience of over 2 months. Manufacturers and dealers are aware this problem exists yet they do nothing. As far as danger it causes is you can't turn off your car, also will lead to battery drain which will leave you stranded in the middle of no where and late for work. Please issue a recall for this problem GM.

I went to leave pulled out of the parking lot, hit my brakes at the light and it sounded like my whole front end was going to fall off the brakes had no pressure and it sounded like it was metal on metal, I had to get home so I thought I could take the long road home that has barely any lights on it. By the time I got down the road they were back to normal and now it-??s done it twice again. I also have some electrical stuff happening where my radial to shut off or not work at all. Also had a couple pistons that had to be replaced earlier and they tried to get me for failure to maintenance but I took my car in faithfully every time I needed oil and I also took it in early because I was using fully synthetic had another 2000 miles to go for me to not have any oil in my car was ridiculous. They ended up only charging me for the seals, but in the beginning it was like 3900.
