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.
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 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.
The contact owns a 2017 Chevrolet Malibu. The contact stated that the vehicle would shut off while driving various speeds and the engine power reduced warning indicator illuminated simultaneously. The contact had the vehicle towed to an independent mechanic who informed her the failure was due to the camshaft vacuum pump. The contact called van Chevrolet (100 nw vivion rd, Kansas City, mo 64118, (816) 527-8564), but no assistance was offered. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 65,000.
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)
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.
The contact owns a 2017 Chevrolet Malibu. While driving approximately 55 mph, the vehicle shuddered, but never stalled. Also, while attempting to park the vehicle, the gear shift indicator showed the vehicle in park; however, the 'shift into park' message appeared. The vehicle was taken to keller motors Inc (located at 1795 S perryville blvd, perryville, mo 63775, (573) 547-1002) where it was diagnosed that the gear shifter needed to be replaced. The vehicle was not repaired. The manufacturer was not contacted. The approximate failure mileage was 47,000. The VIN was not available.
Having issues with transmission (hard shifting, not going into gear, not going into park). This started within a few thousand miles of owning the car. The power steering also goes out at random times. The car gets significantly harder to steer, or turn. Happens when lane departure is turned off as well. Also the adaptive cruise as constantly failing. Almost like the camera just stops working, and the entire system shuts down, or it says its still engaged and cant see the cars in front slowing down. Sometimes the heads up display alert doesn't even go off when it should. Not sure if this is an electrical issue, or each individual system has problems. Car has been at the dealer about 6 times now with the same issues. They currently have the car, and have had it for about 25 days now. Always the same outcome... "we don't know how to fix it". they even had a specialist come in and reprogram the transmission to try to "fix the problem". it hasn't fixed the problem yet. Transmission issues usually happen stationary, going from drive to park, sometimes you will get a loud and very hard shift into gear, sometimes it says its in drive or reverse, you take your foot off the brake, and tap on the gas and nothing happens. It acts as if its still in park. It would also say "shift to park" after you already have and wont let you turn off the car, until it registers you in "park". as for the adaptive cruise, it happens while in motion. Its gotten to the point where I cant even use it anymore. It may work for 3 miles, then completely shut down. Steering issue happens whenever it feels like it. Sometimes while parked, sometimes while driving. Doesn't seem to matter speed wise.
The contact owns a 2017 Chevrolet Malibu. When attempting to park the vehicle, the instrument panel stated that the gear shift must be placed in the park position, even though the gear was already in the park position. The contact stated that the gear shift had to be jiggled or changed into another gear various times before the instrument panel displayed that the shift was in park. The vehicle was taken to koons clarksville Chevrolet Buick GMC (12421 auto dr, clarksville, md 21029, 410-988-9522) where it was diagnosed that the shifter assembly was damaged. The manufacturer was contacted and provided case number: 9-541350439. The failure mileage was 38,680. GM stated the malfunction would not be covered even though it is a safety issue and power train issue and should be under warranty.
I placed my car in park and turned off the vehicle. However, the vehicle's dash stated 'shift to park.' Although the engine turned off none of the electrical shut down and the vehicle sent notification that the keys were left in the car when they were not. This happened several time. An internet search indicated that this is a problem in my make/model of car. This is a 2017 Chevy Malibu.
Indicator light repeatedly comes and says, please shift vehicle into park. When the vehicle is already in park. I will have been pulled in my driveway already in park mode, I will have to keep starting and stopping the vehicle to get the vehicle to recognize it is already shifted gears into the park position. This has happened more than 6 times since I have had this vehicle in the last 2 years
Shift to park light would display on the control panel and the car would not cut off completely.. this issue began intermittently and finally became constant. Diagnostics found internal fault in the shift control. Shift control was removed and replaced at a cost of $394.77 by woodall Chevrolet in danville, Virginia
