2016 CHEVROLET MALIBU Power Train 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 contact owns a 2016 Chevrolet Malibu. The contact stated that after driving vehicle and shifting into park(P), there was a dinging alert sounded, with the “Shift to Park" message displayed. The contact stated that the vehicle failed to turn off. There were no warning lights illuminated. The contact stated that the failure was a known issue and was related to NHTSA Campaign Number: 16V502000 (Electrical System, Power Train). The local dealer was contacted and instructed the contact to shift to neutral and then park. The instruction worked once, but the failure persisted. The vehicle was not diagnosed or repaired. The contact called an independent mechanic who was uncertain of how to repair the vehicle and suggested that the contact check for recalls. The manufacturer was not contacted. The failure mileage was approximately 90,000. The VIN was not available.

I am filing a complaint regarding ongoing and worsening issues with my Chevrolet vehicle, which appear to point to broader defects involving the engine and electrical systems. Months ago, while driving, the car suddenly lost power and displayed "Engine Power Reduced." I had to keep using it due to work needs. Over time, it hesitated more during acceleration and felt increasingly unsafe. When I finally brought it to a Chevrolet service center, I was told the issue involved the pistons. The vehicle also regularly shows a "Shift to Park" warning even when the gear is in Park, raising concerns about the transmission's reliability. The power loss continues, especially when going uphill — again triggering the "Engine Power Reduced" alert and dropping the speed to no more than 35 MPH. A diagnostic showed a P0302 code for a cylinder 2 misfire. The radio head unit, already replaced once under warranty, failed...

I am writing to formally lodge a complaint regarding an ongoing issue I have encountered with my 2016 Chevrolet Malibu. Recently, I experienced a significant problem with the vehicle’s trunk and rear seat release mechanism, which has made it impossible for me to access the trunk or fold down the rear seats. The specific issues I am facing are as follows: Trunk Latch Stuck: The trunk latch has become stuck, and I am unable to open the trunk manually or with the remote key fob. The latch mechanism appears to be malfunctioning, and it will not unlatch when attempting to open it. Remote Key Fob Failure: The remote key fob, which is typically used to release the trunk, no longer works, making it impossible to access the trunk from outside the vehicle. Seat Release Mechanism: Additionally, the release button for folding down the rear seats is also not functioning, and...

A couple days ago I went to drive my car and it took a second to actually turn on and it was shaking way more than usual and pooped up with a message saying “engine power is reduced” I haven’t drove my car since because i tried and it was moving very slow, and i also didn’t wanna cause further issues. For some time now my car has been shaky. i have taken it in and balanced my tires because of this issue and nothing had helped. I am always scared to drive it because it has been so shaky but now that this message has popped up it’s even worse and it’s during my whole drive. Also every time i park it isn’t connecting and says “shift to park” even though it is shifted into park. i have to shake it and press some button to go all register...

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...

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- 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 *No, 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'm having a problem with the car going into park. When it's in park, the doors will not lock in the vehicle will Just drain the battery.

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....

After driving I went to put my car in park and across the information display screen it said shift to park. I have to wiggle the shifter back and forth then the message goes away. Otherwise, the car lights stay on, car beeps at me saying I left the key behind.

The contact's finance owns a 2016 Chevrolet Malibu. The contact stated that the brake pedal would hardened when depressed without warning. While driving at 15 MPH, the contact crashed into another vehicle due to the hardened brake pedal. The driver side air bag failed to deploy as needed; the air bag slightly popped out of place but did not deploy. A police report was filed; no injuries were reported. The vehicle was towed to an independent mechanic where the mechanic verified that the vacuum pump needed repair. In addition, the contact mentioned that the vehicle would independently downshift while driving at a high rate of speed as the "engine reduce speed" warning message would appear on the instrument panel. The dealer and the manufacturer were both notified the failures; a case was filed with the manufacturer. The vehicle had yet to be repaired. The failure mileage was approximately 70,000.

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...

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.

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...

While driving, my car will read reduce power engine, and go to 40mph and then i have to pull over and turn off my car and restart, sometimes it will dismiss the problem and drive normal but sometimes it goes right back to reduce power engine and 40mph again. 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.

Shift into park alert on the dash. I have to restart the vehicle to get it to let me leave the car. It tells me to shift into park even tho I already am.

I was parked idling in a parking lot for about five minutes. 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...

Numerous times my vehicle has not allowed me to shut it off, start it, or move the vehicle because it says that the vehicle is not in park when it very clearly is. I googled the issue and found that numerous other owners have had this issue, and the tech advisor at the dealer confirmed numerous people have had this issue as well. The issue was a faulty switch in the transmission control. 2 different major safety concerns resulted because of this. First, I was unable to start my car in a very bad neighborhood for over a half hour because it kept saying shift to park to start vehicle. Second, I could not shut the car off while parked in the garage because it said shift to park to shut off the vehicle. Both times I was fully in park. This problem is widespread as a simple google search...

My vehicle accumulates moisture and has done so for the past three years or more. As a result there was mildew in the vehicle which was covered under the manufactures warranty and the vehicle was cleaned. Now fast forward a few years there’s a problem with the electrical system as a result of the moisture accumulating in the vehicle. I believe there is a manufacture defect with the Chevrolet model that is causing moisture to accumulate in the vehicle does causing electrical issues with the car

Reduced engine power alert. Ongoing issue since 2019

I have had several issues with my 2016 Malibu. 1st: Putting my vehicle in park sometimes it does not register that it is in park. I have to turn the car on again and try moving the shifter until it registers. 2nd: when accelerating at times i get a stabilitrak error and a check engine light that causes a loss of power. This can happen in the middle of the highway which will cause an inevitable accident. 3rd: saving the best for last. Thw vehicle has recently lost power while driving and won't allow acceleration. Once i stop the vehicle stalls out completely and won't register the gears so i can't out it into park or anything. I was stuck at an intersection and couldn't move. It wouldn't turn fully off because it didn't register it was in park. And it won't turn on or start because it isn't on...

It is currently an intermittent problem on my 2016 Chevy Malibu with 27,880 miles on it. Once shifting the vehicle into park, the gear selector is indicating the vehicle is in park, but the dash board reads "shift to park" and does not allow you to turn off vehicle, it remains in accessory mode. You do not know if the vehicle is really in park because the dash board warning reads "shift to park". If you try several times to put it in park or jiggle the gear selector, the warning will go out and then you can shut down engine. This is unsafe as you don't know when this happens if your vehicle is really in the "park" mode. If you vehicle is not, it could roll or injure someone standing near the vehicle or it's operator or passengers entering or exiting (if it should move unintendedly). I was...

I was sitting at a stop light and all the sudden my car just died in the middle of the road. I to tried to restart and my brake pedal was very hard to push down and on the dashboard it said Engine Power is Reduced. I was not able to start my car at all and had to be towed. Lights and radio were still working.

When shifting into park a dash message appears saying shift to park. The gearshift is in the park position but the message still appears and some electrical devices remain on and you cannot lock the doors.

1. The car when s parked the electronic system does not recognize this and the electronics of the car remain on. Draining the battery and sometimes taking several attempts or more at having to restart the car, shifting through gears in order to get the car to properly turn off. 2. I have been driving down the highway doing approximately 65-75 mph and the car out of no where, with no other cars around has slammed on the breaks and decreased in speed instantly. This has happened twice. 3. Stabilitrak light has come on several times, car violently shakes while ideling. I have already had to replace a piston in the engine. At the time the car was at about 50,000 miles. It is now at 75, 000 and still happens every so often.

I was driving on the freeway at about 65mph, and the car shut down on me. It was extremely dangerous to get over on the freeway with no power. 2 warning lights came on. The Stabilatrak, & the check engine light. I pulled over & called for help. I had the car taken to the service department at the dealership. They contacted me & informed me that a piston was cracked, & the ECM had to have a software update. They are charging me $5,389 to repair it. The car only has 8,000 miles on it. There are recalls for this exact problem, but do not apply to my specific VIN#. My car is a 2016, so I am out of warranty, but this should not happen with a vehicle with this low of mileage.

When I was driving to work, a light appeared on my dashboard stating that my "Engine Power Reduced". When I was in the left lane passing a vehicle, my car slowed down to 40pmh instead of accelerating when I had pressed the gas pedal. The car behind me almost re ended me in the process. This has happened now on a couple of occasions afterwards.

Car began to lose power while driving down the road, then began sputtering gas and creating black smoke. Engine pistons appear to be shot. Car has a little over 100k miles.

When I turn my ignition button off, the dashboard on my vehicle will have the letter P showing that it is in Park, but will have a message pop up on the dash that says "Put in Park". I have to wiggle my transmission lever around while it is in park until it finally clears the message.

My vehicle is stuck on “shift to park message” and can’t turn vehicle off. The vehicle has been displaying this message even thought the car is already on park.

I can be driving and "drive assistance system" and "engine reduced power" comes up and then the car starts to slow down even on the highway and that is ridicoulous.

I was driving to the clinic I go to everyday in the mornings I was in the freeway going about 70mph when suddenly I get a msg saying “engine power reduced” also engine light came on and the car starts slowing down and it’s not letting me go more than 20mph on the FREEWAY! I could have caused an accident, (this is very unsafe specially since my 2 and 4 year old were in the car with me) I got off on the next exit and pulled in to a gas station and turned the car off and waited about 10 mins I turned the car back on and the msg was gone but the engine light was still on about a minute or 2 later the msg comes back on so I have to pull over again, it did it about 5x before I can make it to my...

The morning I started my trip. My back up camera stayed on. I stopped turned the car off and back on. It was still on. Turned it off again. This time the camera went off. I was going up the cajon pass. No warning light or anything. Was coming up to my exit. Tried to slow down to exit. Couldn't press my brakes. They were rock hard to press. Took my foot off gas. Slowed down enough to get to the shoulder of the road. Once I was able to stop. My brakes were hard to press they made a clunk noise. I noticed the check engine light was on. I could of been killed had someone been in front of me and stopped. Or I could of killed someone. This is not the first time these brakes have done this. They did it earlier this year I wasn't able...
