2016 Chevrolet Malibu Driver assistance Problems

I am reporting a recurring safety defect related to GM’s known “Shift to Park” issue. My vehicle displays a “Shift to Park” warning even when the vehicle is already in park, preventing the car from shutting off properly and creating a safety risk. This issue has been widely reported and associated with GM recalls and service bulletins. GM previously repaired this issue once while my vehicle was under warranty, acknowledging it as a known defect. The same defect has now reoccurred after the warranty period expired. GM is refusing to repair it again, despite the issue being recall-related and tied to a known defective design rather than wear and tear. This defect affects safe vehicle operation, risks battery drain, rollaway hazards, and driver distraction. I believe this is an unresolved safety defect that should be covered regardless of warranty status.

The engine power reduced came light came on along with service stability trac. The car would stall after going into auto stop and just shut off. In certain instances it would shutoff when slowed down enough. It was brought in for service where the turbo charge solenoid starter and catalytic converter annd alternator all were replaced due to the turbo braking into pieces and being lodged into the converter and engine. Less than a week later the car returned to stalling at the auto stop feature. When brought in for service it was linked to the alternator and engine control module and mass air flow sensor. The car was then serviced again six months later for the alternator again. Now the car is once again stuck in engine power reduced with no direct codes linked to the problem and the starter was replaced and now the engine is remaining in limp mode. The car has stalled multiple times on not only at stop lights but on the highway and while turning at busy intersections causing traffic jams and even a side collision. The engine light as remained on since the day I got the car.

Engine power reduced defect, causing affected models to lose power while driving at highway speeds. My son’s was driving 55 mph and then all of sudden the car decelerated to 20 mph in minutes before his 2016 Malibu stalled on [XXX]. Unfortunately the car did not make it to the emergency lane and as a result a SUV hit his car killing my daughter who was 33 weeks pregnant. The baby survived with lifelong injuries. Despite this recall, GM failed to notify vehicle owners, including the owner of the vehicle involved in the fatal accident on [XXX], in Dallas, Texas, resulting in my daughter’s death. This defect has been found in several 2016 Malibus, prompting a class action lawsuit against GM. Plaintiffs in the class action lawsuit reported having to restart their vehicles or replace faulty accelerator pedal position sensors to address the issue. GM's failure to notify vehicle owners of the safety recall constitutes negligence and gross negligence. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Happened around 46000 miles after receiving a recall notice in the mail about the pedal positioning sensor causing a reduced engine power signal, and immediately reducing speeds on the interstate. Local Chevy dealership replaced. Fast-forward 80K miles and the same incident is happening, however likely not going to be covered by GM. Same message, same code being detected.

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)

Out of nowhere, a notification pops up and it says “engine speed reduced” and all of a sudden you can feel the car losing speed. Took the vehicle to the dealership multiple times and either they always say it’s a fuel injection problem or they have no idea what’s causing it but when they perform that service on the vehicle, it still happens. Dealership even told me once that my car computer system needed to be updated and once updated I wouldn’t have the issue and I still have the issue. Each time the engine speed is reduced, a notification pops up that the StabiliTrak needs to be serviced. My safety and life is at risk because I’m going 65 mph down the interstate and all of sudden my engine speed is reduced like I’m not in the middle of traffic with cars going at speeds between 60-75 mph. I almost got ran over by an 18 wheeler because of the engine speed reduction. I had to swerve hard to the side of the road and risk flipping or crashing to get off the road so I wouldn’t be hit

While driving at a fast pace a hazard message pops up on dash that states engine power reduced and the car goes slow unable to accelerate past 20 mph. It doesn’t happen all the time but it’s been happening quite frequently and it’s dangerous. I’m assuming there has something to do with the speed and or fuel function. The vehicle has not been inspected. I am willing to bring it for inspection if needed. I feel like this is a malfunction and I’m requesting this to be fixed.

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.

Lights that alert inside the vehicle at random times but more often in the last few months are: stability trek, power steering reduced and check engine. Acceleration decreased/reduced after being idle. This prompts serious danger for myself and children when there is no power being given to the car when sitting in traffic. Multiple mechanics have diagnosed the issue. Dealership gives me the run around and isn't specific with detail if check light engine goes off.
