What 720 owners told NHTSA about the 2017 Chevrolet Malibu Limited

I was in the freeway and out of nowhere an alert message popped up on the dashboard saying Engine power reduced. This made my car go from 65mph to 30 mph is the freeway luckily I was able to exit and go to the nearest gas station and was able to keep myself safe as others on the road but it could've easily gone very badly. The car won't go over 30 mph. The car is available for inspection upon request, I seen a PDF in the nhtsa website of a special coverage adjustment for loss of continuity within acceleration pedal position circuit. I will attach it to this message.

High pressure fuel pump blew out while driving on the highway going to Minnesota from Illinois. Fuel was spraying onto the engine and leaking onto the ground. I immediately pulled over and stopped the car, turned off the engine and raised the hood. The car was taken to a Chevy dealership today and I was informed that the high pressure fuel pump literally "blew out." This could have resulted in an engine fire and fortunately that didn't happen. Online research reveals that Chevy had a recall on some 2016-2018 model Malibu's for this very reason.

The Power Brake Vacuum Assist Failure nearly caused a wreck. The part failed while we were driving on [XXX] going 65 miles per hour on a busy highway. As the breaks gave out the engine light said “Reduced Power”. Moments later, the breaks stopped working and the engine stopped running. We were able to coast off the highway and into an HEB parking lot and have the vehicle towed. The mechanic took the part off and found that it was in pieces causing further examination of the engine to look for the missing metal. Pictures are available to see the damage. Even after completing the repairs the vehicle is showing reduced power. We are still trying to get it fixed but understand that the Chevrolet company is aware of the issue but never issued a recall.

On numerous occasions while driving on highway my dashboard will display reduced engine power and engine light comes on. My traction control light also comes on. Car loses power quickly and will not accelerate. I’ve had to pull over numerous times almost being hit by cars behind me. Took it to get repaired and had to have fuel pump replaced as wires had melted to side of pump. Three months later same problem happened. This car is scary to drive

Ice and sludge accumulated and froze causing the CAC system to fail resulting in engine issues, performance loss this was caused from GM poor design of a shield that they are aware of. GM knows that this can happen and have now designed a new shield to prevent this from happening but it is at the owner’s expense to fix. If GM knows that this will happen they should fix the issue I am now out of pocket 3,000.00 shame on them

In February 2023, we took the Malibu into the dealership for reduced engine power dashboard notification. Light went off when in shop, got the car back and light on once again. When at a red light that turned green, accelerated but car would not go over 20 MPH. Almost rear ended. Dealership replaced the vacuum pump gasket and seal. Fast forward one year later. Once again, reduced engine power notification came on again. Once again at red light, when light turned green, car wouldn't accelerate and was very close to being rear ended and difficult to make it through the intersection. Currently at dealer (1/18/24) with dealer having no idea what is wrong with car (today is 1/24/24). The dealer today stated it will be another 1-2 weeks. That will make it three weeks for a diagnoisis. With reduced engine power, it is very dangerous to drive a vehicle like this. Of course, there are hundreds of other complaints for this issue/make/model.

My car displayed "reduced engine power" and slowed down on the highway while I was doing 65mph. My car would not accelerate past 20mph. There were no issues with my vehicle, and this happened out of nowhere. It caused a lot of other drivers to have to swerve around me, and drastically reduce their speeds as well in order to avoid collision. This was highly unsafe and now I can not safely drive my own car.

Check engine light came on. Display stated that the engine will run at reduced power which meant we had to Limp home at 15 MPH which put us in a dangerous situation. I read the code and it was P2122. Throttle/Pedal Position Sensor/Switch “D” Circuit Low Input. This indicates that there is a problem with the accelerator pedal. I replaced the pedal myself at a cost of $114.00. I eventually found a technical service bulletin that admitted that there is a problem with the accelerator pedal on 2016 to 2018 GM vehicles and there was a program that was replacing the pedal until 2020. I called GM customer service and they said there was nothing they would do about it since the program expired in 2020.

I receive a "shift to park" warning when putting the 2017 Chevrolet Malibu I just bought into park. The car will not shut off and if I exit the car it will sound the horn at me 4 times and still not shut off. It's done this at least 6 different times in the 3 days I've owned it. I bought it used on 10/31/23 with 86,741 miles and have only driven it 200 miles. If the car is not actually in park then it is still able to move and can hurt someone. This is clearly a known defect spanning multiple models and years and likely many thousands of cars and it's criminal there's no recall for it with a proper solution.

Error message reads "Engine Power Reduced". I was on the highway and suddenly the engine gives out and only lets me go to a max capacity of 20 mph. I able to safely remove myself to the side of the freeway. A week later without moving my vehicle I checked to see the status of my car and the error message removed itself. It's been over a year now with my engine power coming and going, just as fast as it comes, it goes-- making driving very unreliable and unsafe to step onto the road. Apparently I'm not the only one with this concern according to [XXX] , a class action lawsuit has been charged against Chevrolet in The Rothschild v. General Motors LLC Chevy Malibu Class Action Lawsuit is filed in the US District Court for the Eastern District of New York under case number [XXX].

Upon turning off car, throws shift to park error driver message. Have to restart the car, then shift to various conditions - R, D, L several times then P then turnoff car again. Repeat unto message no longer appears. Sometimes I cannot restart the car because it’s not sending the ke fob. I read online several complaints. Took car to dealership - they confirm that this problem exists in both older and several new Chevy model. My costs will be around $1k by replacing the gear shifter which I find scary. What if this car had jumped out of gear. What is the life of the replacement shifter? Why isn’t GM doing anything when this condition exist in brand new vehicles?
