What 810 owners told NHTSA about the 2016 Chevrolet Malibu Eco

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.

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 destination not to mention the way back home I had to stop about 3x more. This is very unsafe and something has to be done as it is not only my car with this problem.

My problem started with the engine first sending me a code “reduced engine power” and this code would appear one week and gone the next. I have taken it to mechanics and had parts replaced and temporary fixes. After getting it back from the mechanic and them telling me that the cylinder one isn’t holding the correct pressure and the exhaust value is burnt due to the consistent auto engine shutoff. The day I got it back on the road the engine went full shutdown at a stop light and would not turn on immediately. I was lucky enough to get it running long enough to crawl into a gas station and get a tow truck to come pick it up and tow it back to the mechanic shop and that’s where it’s been sitting there till I find a new engine to replace it.

Driving on highway at speed of 70mph during rush hour very very busy when my car shows a warning engine power reduced and slows all the way down to 20mph lucky I was able to get over the 3 lanes of traffic without causing an accident but this is very unsafe I looked to see if there was a recall on the vehicle but there’s not so I had a mechanic look at the car and they said nothing is wrong with it ??? Well today on my way home it did it again!! I’m sorry but how is nothing wrong with it if my car is slowing to a dangerous speed this issue could cost someone their life

While driving several times I had the problem where the car out of nowhere slows down and the message comes on engine reduce power, I have been on the highway with my family and out had to pull over turn my car on and off several times for it to come off and be able to drive my care pass 20 miles per hr. This is very dangerous because it happens suddenly and cars are going by fast I almost got into an accident and was rear-ended on the highway. There needs to be a recall on his engine this is ridiculous that GMC/Chevrolet keeps getting away with this until someone is seriously injured or killed because of this failure!

Driving along and Reduced Engine Power warning message came on said can not go above 20 mph but yet car still could be accelerated above 20mph. Pulled over when could. Stopped car and turned it off and on. message gone but engine warning light still on. OBD2 stated P2122 error. Upon reviewing internet there are class action lawsuits going on because can create a very dangerous scenario if car suddenly stops in the middle of the highway.

Was driving home from a job interview about two hours away from home, traveling at 55 mph when the vehicle reduced speed rapidly to ~ 15 mph and on the dash a warning message appeared stating that I had reduced engine power. The situation was incredibly dangerous as there was snow piled on the shoulder, leaving me with no safe way to quickly get out of the way of fast-moving traffic. Once out of the way and after restarting the car and seeing no warning lamps, messages, or anything indicating there were ongoing issues, I turned my hazards off, my turn signal on and made my way back onto the roadway when there was enough distance between myself and the next oncoming car. Upon re-entering the roadway and reaching 24 mph, the car display the same message and reduced speed to max of 12 mph and I was nearly rear-ended by the driver I entered the roadway in front of (with more than ample time and distance to safely reach the speed limit). After several more attempts, I placed hazards on and continued on side of roadway as far as possible. Drove to an AutoZone where they were able to scan my car and informed me that the code I received (have printed doc of code being thrown with date of incident from AutoZone) was very common in the 2016 Chevrolet Malibu's and he recommended that I see if I can return the car to the dealership (had just purchased less than 60 days prior with 78,000 miles on it).

Engine power reduced, reduced power to the vehicle regardless of speed.

Three times now I have had the warning “engine reduced power” pop up on my panel all times that I drive to my military base for work. Thankfully I haven’t been involved in an accident yet, my highway speed has went from 60mph to 35-40mph due to this issue. I was told I needed to purchase another pedal because of it not responding to the engine but after a second opinion I was told there was something wrong with the computer itself. That there’s faulty wiring which I don’t have the funds to cover because how much it would have cost. I also don’t have the funds to drop on another vehicle so at this point I’m driving a human boobie trap not only for myself but for other drivers around me. I pray no harm is done to anyone else who also owns this vehicle and having the same issues.

I was driving to work this morning at 50 miles per hr then suddenly my car reduced the speed and the motor light turns on it showed me reduced engine power sign and the motor light turns on

I was driving down the Freeway at 65 mph. The roads were wet and slick from snow and in heavy traffic. I got a check engine light and immediately a Engine Power Reduced light. I suddenly lost power and another vehicle behind me almost hit me. I was able to get to the side of the road and shut it off. After a few minutes, I started it back up and the light was still on. I needed to get off the freeway and find a way to work so I put on the emergency flashers and drove to the next exit. The light remained on but I had full power. I am trying to get an appointment to have it looked at.

I was driving on a highway approx 60 miles an hour when a message came in my dashboard stating reduction in engine power, the vehicle abruptly slowed to 20 mph without any warning and I was barely able to pull my vehicle off to the side of the road without being rear ended by the vehicle behind me on the highway.

NHTSA ODI 11444572

Engine power reduced light came on as I was driving 55 mph on the freeway and my vehicle immediately slowed down to under 20 mph putting me and my wife lives in danger by almost having several vehicles crash into us. This has not just happened to me but different people I’ve asked with Chevy Malibus. This problem needs to be fixed by General Motors at NO COST to the consumers. I can’t believe there’s no recall on this issue. Shame on them.

I have been getting many of notifications from my car stating that the engine power has been reduced and i am unable to accelerate past 40 max. I travel quite often and drive to work 7/7 days a week and the roads i take are heavily traveled so because of this i’ve almost gotten into many many accidents due to the accelerator failure.

I was driving on a highway, when a message appeared on my control panel stating the engine power was reduced, my engine light turned on, and my car slowed significantly (top speed achievable at about 20 mph). With my hazard lights on, I managed to safely exit the highway and find a parking lot to park in while checking my driver’s manual. The manual mentioned that if the warning light persisted, the car should be checked by a mechanic. As this made it seem that there were instances where the warning message did go away, and thus the problem may also resolve, I turned off my car and turned it back on. The engine light on my control panel persisted but the engine power message was no longer present. Before reentering the highway, I attempted to reach speeds above 20 mph and was successful in doing so. As such, I cautiously finished my journey to work. As I felt it was unsafe to use my car before it was checked by a mechanic, I had my car towed to a mechanic’s shop where I was informed: “Found DTC P2138 accelerator pedal plausibility. Inspected the IP to body harness connector for water intrusion or corrosion and found none at this time. Suggest replacing the accelerator pedal assembly and recheck for proper operation.”

"Engine power reduced" notification while driving on the highway causing rapid reaction to pull to the shoulder of the highway. This happened 3 time this morning on my way to work.

NHTSA ODI 11440981

The contact owns a 2016 Chevrolet Malibu Hybrid. The contact stated while driving at various speeds, the vehicle would not accelerate above 60 mph, with the accelerator pedal depressed. The contact stated that the engine power reduced warning light was illuminated. The vehicle was taken to a local dealer where it was diagnosed with the accelerator pedal sensor needing to be replaced. The vehicle was repaired. The manufacturer had been informed of the failure but offered no assistance. The failure mileage was approximately 26,000.

I have a 2016 Chevrolet Malibu and while driving on the highway, my engine light came on and my speed decelerated from 65 mph to 40. I took my car for a diagnostic test and the results were Trouble Codes: P2138, U0401-71 and C0242-00. I have done my research and from what I have found so far, is that several people have made Youtube videos about these codes, complaints and complaints on this website as well, and it has come to my understanding, that if enough people complain that this can be a safety issue, then maybe the "POWERS THAT BE", will help with this issue and possibly resolve it. This is and can be dangerous for an individual to drive at the average speed on most U.S. highways, 65, and they decelerate without warning down to 40 mph. I'm not sure why anyone does not se the dangers in this situation, especially with other motorists on the road driving at speeds of up to 70 mph, sometimes 75 mph. If I have vehicles behind me driving 65 or more and my vehicle decides to decelerate because of a sensor failure, the vehicle behind me is not going to know that there is a problem and may not have enough time to react before causing an accident. I am adding my concern not only to many individuals who have reported the same or similar experience , but in hopes that this issue would gain more attention.
