When you shift to park a light comes on that says it isn't in park. So the lights will not shut off. You have to repeatedly shif from drive to park until it turns off. There are thousands of complaints online. It cost me $286 to fix it I was 1000 miles over my warranty.

When parking the vehicle and turning off the ignition the dash lights up "shift to park" had to work and work with it to get the car into park to where it could be exited from. Took to dealer and with extended warranty had to pay $200 deductible for a fix that I have heard many are having with the 2016 and 2017 year model GM products.

I was traveling in my vehicle on the highway going at least 65 to 75 mph and all of a sudden my vehicle beats two or three times and across the screen came the words 'reduce engine speed'. at that moment I was traveling in the middle lane and I had to safely get over to the far right median in the middle of traffic safely turn off and wait at least 10 minutes to start it back up. When I started my vehicle back up again I still received the same message. I then waited even longer and everything was ok but eventually the same issue continued to happen several times. I took my vehicle to get coded and the codes that were given to me were 2122, 2123, 2101. It's unsafe for this to happen especially I have a child this is no safe for me.

For 3 months my 2017 Chevy Malibu has had the check engine light come on, and vehicle completely loose acceleration. At slow and high speeds with my 2 year old in the car. When the code is read it states it's the ECM P2138. This last time almost caused my vehicle to wreck with my family in the car. Chevy has yet to handle the issue and like most cars it's not covered on warranty so because Chevy has put out a faulty product we are being punished with high mechanical costs. This is not the first issue, I have have my Chevy almost 3 years and have had it in for sensor issues reading the key fob and my car stranding me hours from home and not starting, and again for sensory issues putting the vehicle into park. When confronting Chevy they state the issue with high cost to fix.

While driving on freeway going 70 mph, my traction control, check engine light, and a warning flash across my dashboard saying engine speed reduced. My car went from going 70 mph to 40 mph and wouldn't go any higher. I immediately got off the freeway took pictures of the lights. Luckily I have a anti left device that reads off codes for my check engine like code P2138 is what came up. This is extremely dangerous, I had my [xxx] child in the car with me and was almost rear ended due to loss of power from such a high speed.

When driving the car, it will suddenly decelerate. Check engine light appears with the following message "engine power is reduced". this has happened many times in the last 2 months and has not been fixed by GM.

- Norton Shores, MI, USA

Driving at about 55mph then without warning message on instrument cluster showed low power engine mode with emission warning icon illuminated. Speed dropped almost instantly from 55mph to about 35mph!!!!! setting stage for possible rear end collision but was lucky this time.

Vehicle abruptly slowed in heavy traffic for no apparent reason. Vehicle was diagnosed as having a faulty accelerator pedal. Part was replaced at owners expense 14 months into the life of the car. 8 months later the vehicle started to do the same thing for the next 5 months, sometimes 3 to 4 times in one day or not al all for several weeks. Car was again presented to dealer for diagnostic and it showed that the same fault occurred. This is a severe safety issue that needs to be addressed by General Motors. Fault codes P2138 for accelerator pedal, C0242 and U0401 for traction control system. Neither of these faults were addressed by the dealer during the repair.

My 2017 Chevy Malibu has periodically showed a reduced power mode alert in the dash while driving and then the car drops down to under 40 mph and when I push the gas it won't accelerate. The check engine light comes on every time but within days it goes off and drives fine until it happens again with no warning. My husband was driving 70 on the interstate when it first happened and almost wrecked because of it! I have called the dealership where they tell me they don't know why it's doing it and to just bring it in. I had the engine codes pulled and was told it was a sensor and acceleration pedal. I've read several posts about what's wrong with it and everyone says even after having it fixed it goes out again within time. It's really dangerous when yours driving at high speeds with traffic then the car randomly try's to shut down and Chevy is not concerned at all about finding a permanent fix!

The contact owns a 2017 Chevrolet Malibu. The contact stated that the vehicle would shut off while driving various speeds. In addition, the park assist and check engine warning indicators illuminated. The contact took the vehicle to stivers Chevrolet (111 newland rd, columbia, SC 29229, (803) 254-1431) where they were initially unable to diagnose the defect. After multiple failures, the contact brought the vehicle back to the dealer where they diagnosed the vehicle with a faulty sensor. The part was replaced, but the failure continued. The manufacturer was notified of the failure and did not assist. The vehicle was not repaired. The failure mileage was 3,000.

The electrical blinks out. Engine reduced speed is a problem and is very damgerous I was almost hit on the freeway. This car is a dud and most models like it have the same problem.

While driving my 2017 Chevrolet Malibu on the highway with my son in the car, the driver screen dash flashed a message 'engine power reduced', the check engine light turned on, and the car immediately lost power making it difficult to drive safely. After this happened, my car would not exceed 45 mph and would not shift. After pulling my car to the side of the busy highway and letting it set, I was able to get my car towed to my home. This has since happened five additional times and is happening at a more rapid rate. I took my car the oreilleys and autozone to have them run a general diagnostic check and the error code being returned was 'P2138' - 'throttle/pedal position sensor/switch D / E voltage correlation'. I then set up an appointment with the Chevrolet dealership, where technicians also ran a more thorough diagnostic test and found my car needed a new accelerator pedal position sensor. This part is not functioning as it is supposed to and at the very least is an extreme safety hazard.

Car will indicate 'engine power reduced' and will abruptly reduce speed. This is a major safety concern not only to myself but other drivers on the road as well. Why is there no recall for this problem? I see it is a major problem with these models of Chevy Malibu. Happens everyday, most of the time more than once. My commute to work is about 25min and it did it 3 times today.

After driving, vehicle parked and gear shift to park. Vehicle is turned off but warning light on dash says 'shift to park'. vehicle stays 'on' (radio etc) engine is off. When you exit car to lock you get a double beep indicating car is still on. Use to happen every once in awhile (1/week) now it happens every time I drive it. (4X day)

Going into park the car says you need to shift to park. Car will not shut off.

For three weeks I have been getting a "shift to park" error when I place car in park. It prevents me from fully turning car off and will not allow doors to lock. I have to play with the shifter to get the warning to come off. Last week it was in the shop at basil Chevrolet in depew, NY and they replaced the shift relay and it is still doing it. Today while driving down the highway my car suddenly showed the check engine light, the traction control light, slowed down to approximately 10-15 miles per hour and showed "reduced engine power" warning on the dashboard. I was in the middle of rush hour traffic. I was able to get into a parking lot but the car would not shut off and the "shift to park" warning showed. Finally got that error to go off and shut off car. Car was able to restart with only the engine light on. Stayed on for the next 35 miles. Just went back out at lunch time and now no lights and it was driving fine until I tried shutting off and the "shift to park" wouldn't go off no matter how much I tried to wiggle the handle. Car going back to dealer at 5pm.

Reduced engine power is a norm for these new Chevy Malibu's my engender is reducing power again. They charges me $345 last December 3018 to replace the accelerator pedal and this October 2019, it's doing the same thing. It will reduce speed on highway under 50 mph and I could have been hit by other cars if they did not notice.
