2017 Chevrolet Malibu

When the vehicle is shifted into Park and the ignition button is pressed, the vehicle fails to shut down. The dashboard displays a "Shift to Park" warning message, indicating the vehicle does not recognize that the gear selector is physically in the Park position.To shut the engine off, the driver must repeatedly wiggle, slam, or cycle the gear shifter back and forth into Park until the electrical sensor finally registers the connection. This creates a severe safety hazard, as the vehicle can roll away if left unsecured, drains the car battery, and prevents the doors from locking properly.Crucially, this defect traps drivers inside an operational vehicle for extended periods while they repeatedly struggle to force it to shut down. This poses an immediate risk of heat-related illness or death (hyperthermia), especially in high-temperature environments, during heatwaves, or for vulnerable occupants like children and the elderly who cannot exit the vehicle safely until it is off.

I have a 2017 Chevy Malibu 2.0 T. The incident involved the braking system. I was driving and as traffic came to a stop, I pressed the brake to stop and my brakes gave out. I immediately lifted my foot and press extremely hard on my brake pedal and was able to stop though the stopping distance was much further and nearly caused an accident. I have now taken the vehicle to a Chevy certified dealer and it has been identified as a brake vacuum pump failure. GM has had many issues with the brake vacuum pump across many of its models.

I was driving back home and stopped at a red light. When the light turned green I started driving, but my car was jerking a little too much. I pulled over and turned my car off. When I cut my car back on my brake became very hard to the point I had to push down extra hard to stop my car. I started back driving home once I realized my car needs to be turned completely off and sit. While I'm driving I see a message on my dashboard saying "Engine power reduced." Luckily I made it home safely with no wrecks, but when I had to brake my car was still moving jerking while in place. Also when I made it home and turned my car off I heard a fan like noise that eventually stopped.

the trottle body position sensor just started acting up. took it to mechanic. they stated they can try to fix it but it may only work for a month then go back out. may end up paying over 6k and the car isn't worth it

Shift to park error on dash. GM is aware of this issue and won't do anything about it. This causes stress and can cause battery drain. The issue lies within the microswitch that reads that the shifter is in park. The metal arm that activates the switch wears down or the wiring is faulty. Several Malibus, as well as other models have this issue and Chevy dealerships want hundreds to thousands of dollars to fix this. If it's a known, repetitive issue on several models, it should be a recall. This causes owners to try to fix this issue themselves, which can cause more damage and more money.

MY BACK-UP CAMERA HAS NOT WORKED IN ABOUT 3-4 YEARS. THE SCREEN IS COMPLETLY BLANK. MY MECHANIC WILL NOT TOUCH IT AND I'M AFRAID TO GO TO THE DEALER BECAUSE OF THE COST. I DID NOTICE THERE IS A RECALL ON NEWER MODELS OF THIS VEHICLE.

The SHIFT TO PARK warning light comes on when shifting to park and WILL NOT allow you to shut the vehicle off. This is a WIDELY KNOWN DEFECT in multiple GM vehicles and yet there’s still no recall! WHY?! It causes the vehicle to not completely shut down, killing the battery and could potentially cause the car to roll. It’s been WIDELY REPORTED and it’s absolutely a defect with a part inside the shifter! It’s an expensive repair that consumers SHOULD NOT have to pay when it’s a DEFECT on GM!!! PLEASE RECALL!!!!!! After researching this issue, there’s MULTITUDES OF COMPLAINTS and even a class action lawsuit (of which I wasn’t aware of) but it shouldn’t have to turn into a lawsuit when the NHSTA has the ability to force GM to MAKE THIS RIGHT by REPAIRING IT!

The contact owns a 2017 Chevrolet Malibu. The contact stated that while driving at various speeds, the message "Engine Power Reduced" was displayed, and the check engine warning light was illuminated. Due to the issue, the vehicle went into LIMP Mode, and the contact was forced to pull over and turn off the vehicle. The contact waited approximately 30-40 minutes before restarting the vehicle and resuming normal driving. The vehicle was previously taken to a dealer; however, no codes were found. The mechanic informed the contact that the failure could be caused by the floormat being under the accelerator pedal. The contact had the floormat removed; however, the failure persisted. The dealer was notified of the failure, and another appointment was scheduled to service the vehicle. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was unknown.

When car is in park. Shift to park is on dashboard. Car won't fully turn off. It's been doing it for years. Was worked on at dealership. It's still doing it.

In the last 6 months I’ve had to put 3 Brake Boosters on my 2017 Chevy Malibu and it’s NOT cheap…. I don’t know what else to do.

The Reduce Power to Engine keeps happening. It shuts my car down and lights up the traction control light, check engine light and its a serious hazard because I travel highway to and from work and its very dangerous when you loose power to your vehicle at high rates of speed. Also my emissions is bad due to a supposed fixed recall for the catalytic converter.

I was driving my car on the highway and the car begin to feel like it was about to shut off. Shortly after, the car check engine light turned on with a warning sign on dashboard stating “engine reduce.” the check engine is still on and my mechanic states my turbo needs to be replaced. I have an appointment for second consult with chevy dealer to verify.

The GM Shift to Park recall has been an issue that has affected various General Motors (GM) vehicles. The primarily impacting Chevrolet models like the Malibu, Traverse, Volt, and the 2019 Chevrolet Blazer. It’s essential to be aware of the problem, its implications on vehicle’s safety, and the steps required to address it. In simple terms, the Shift to Park defect prevents drivers from shutting off and locking their vehicles, even after putting the car in park. This situation poses a potential safety concern, as drivers might mistakenly assume their cars are securely parked and powered off while walking away. The issue has been prevalent enough for the company to issue a Technical Service Bulletin (TSB) on June 7, 2021. The TSB specifically targets the 2017-2018 GMC Acadia, while also mentioning the Malibu, Traverse, Volt, and other 2016-2019 Chevrolet models. The bulletin provides guidance on diagnosing and addressing the “Shift to Park” problems, although it does not present a definitive solution to the underlying issue. GM CUSTOMER SERVICE REFUSES TO FIX IT

I have had experience with the "SHIFT TO PARK" error and I have had the "reduced engine power" error message resulting in an UNEEDED $2200 dollar repair only for it to break down 2 months later, same message this time with fuel spraying under the hood. I NEARLY BLEW MYSELF UP TRYING TO START MY CAR! How is it that I cant find this DANGEROUS defect on the recall list when I easily found the RECURRENT problem online? HELP

While driving at highway speeds, my vehicle suddenly experienced a loss of engine power and reduced acceleration. The traction control light and engine light illuminated, and a “Reduced Engine Power” message appeared. The vehicle would not respond to the accelerator, creating a serious safety hazard. This occurred shortly after authorized dealer service involving the PCV system and related components. The vehicle did not have this issue prior to dealer service. I returned the vehicle to the dealer, and they stated they could not replicate the issue. The sudden loss of power could have resulted in a serious accident. I believe this may be related to improper dealer service, disturbed electrical connectors, or throttle body/engine management components. I am reporting this as a safety concern. I also would like to mention this safety issue has occurred now multiple times with my car on multiple separate occasions with the last prior occurrence being 12/20/2025.

Lose power while driving

Was driving on highway and starting to exit and my engine light came on and it alerted reduced engine power. I had to slam on my brakes but they were very hard to press and almost non existent and steering was also difficult. Managed to get car to side of road but due to very hard to non existent brakes I did graze a truck and damaged my rear drivers side fender. I am very lucky I didn’t get injured and was able to mostly miss the cars stopped in front of me. I also have the shift to park issue happen at least 4 times a week.

Reduced engine power. Car will not accelerate over 35 mph. Almost rear ended. Will be the second time in dealer for same problem. Also, Shift to Park. Also second time at dealer for same problems. You cannot get out of car until you keep moving the shifting handle.

Fuel is leaking and it is messing up my emissions. I had the emissions fixed for my safety inspection. But soon after 2 days later fuel keeps leaking and the smell of gas is so strong in my car. This is a safety hazard of not only becoming inflammable but also the smell is toxic to my health and my grandchildren. I have asthma and all of the following i have experienced headaches, dizziness, and respiratory problems, and long-term like asthma exacerbation that is flaring up my asthma and i am afraid it will cause potential cancer.

Engine light is on, message pops up stating "engine power is reduced" and pedal acceleration is limited. I received a message from Onstar stating there is a recall on some GMC vehicles regarding this issue, however my vin is not part of the recall, but it should be, as all the elements stated in the recall are the exact issues in my vehicle.
