About 6 months ago, I was driving in the interstate going about 70 mph, when my vehicle dropped its speed to 20 mph advising of ' reduced engine power ', the speed did not decrease which caused a hault & jerk. Which could have turned fatal if there was a vehicle behind me. October 30th, I was driving about 30mph in a residential area when I approached a stop sign and my vehicle suddenly lost power, after about 3 minutes I was able to start the vehicle and drive to the dealership. The battery and a sensor had been replaced. Exactly two weeks later, I was driving on the street around 25-30mph, approached a stop again and car powered off.. immediately taken to dealership and they could not identify the problem. This is a huge safety hazard, I do not drive on the highway out of fear that the car may shut off. I've been to authorized dealerships & had the transmission checked out by certified transmissions shops and can't source the problem

I was driving on a road at 47 miles an hour. Out of no where, the car slowed all the way down to 15 miles an hour. On the dash board a notice flash stating "engine power reduced" I was barely able to navigate out of traffic without being hit. Then it happened again several hours later when I was on my way home, I had to constantly keep pulling over.

My 2017 Malibu has 65,000 miles on it. In the course of three days a warning kept popping up every time I came to a stop the car engine would turn off for a second and then turned back on with a warning that stated service stability track, driver assisted steering not engaged. Today I came to a stoplight and the engine completely died leaving me stranded there for about 15 minutes until I was finally able to get it started again and moving. I had to put the car in manual mode to get it to drive. I am awaiting the estimate from the dealership to see what it would cost to fix this. I have read scores of other reports of the same thing happening on these cars. To the point where some people are driving and it stops. This is a serious dangerous problem and it needs to be addressed by General Motors.

Driving down the interstate (with my family) at 70mph and loose power. Display shows "engine power reduced" just about got rear ended by a semi due to power loss. Had to get over to the shoulder while dodging traffic from behind me. Very dangerous. Needs to be corrected and covered by GM.

After putting my 2017 Chevy Malibu into park, I received a "shift to park" message on the dash. The car would not fully turn off. It stayed in auxillary power mode. Doors would not lock, emergency lights stay on and had a beeping sound. The problem was not resolving itself irregardless of how many times I turned it off and on. The failure mileage was approximately 8,400. (yes, the mileage is 8,400. This is not a typo.) the vehicle was taken to martin Chevrolet, located at: 23505 hawthorne boulevard, torrance California, 90505. The service representative said this is a recurring problem and they have seen it multiple times. (it is a tranmission control assembly failure). I asked if it was a design flaw and he concurred. He said there was no recall at his time but they are expecting one. I spent $550 to have the replacement done. General Motors needs to declare a recall and refund my money. A two year old car with 8,400 miles should not be incurring major expenses for faulty components.

Car stopped while driving on a highway with a message on dash saying 'engine power is reduced.' The dealership first said it was the accelerator pedal, then said it was the engine control unit. They said that they don't know what causes this to happen, but it just needs reprogrammed and a software update. An update that only a GM facility can do. Also specifically asked if this was wear and tear, told no, they don't know why this happens.

I was driving at 70 mph on a highway and the car shut of causing me to nearly get hit multiple times. I was barely able to get the car to the off ramp I was approaching. I had the car towed 100 miles to my house and then to a dealership. The dealership determined that the vacuum pump came apart and sent metal everywhere. The vacuum coming apart also caused the camshaft to break along with a hose and a camshaft sensor. The repairs alone are estimated so far to cost me about $2,500.

"shift to park" when placing car in park which does not allow vehicle to fully power off. This is the second time this vehicle has had this issue. It happened at 37K and I had it repaired which cost close to $600 just under a year ago. The vehicle mileage since the repair is under 30K.

Getting shift to park message when putting car into park. Unable to turn vehicle off until park engages. We had repaired at the dealership a couple of months ago and it is doing it again. It is beginning to do it often.

Beginning several months ago, the vehicle would occasionally display a "shift to park" error message after the "start/stop" button was pressed to turn off the parked vehicle. Although the engine would turn off, all of the electrical systems would remain on. For the first few months, the error message would disappear after a few seconds to a minute, after which the "start/stop" button to be pressed to turn off the vehicle completely. Over the last month, however, the amount of time the message stayed displayed increased to many minutes, and it would take turning the car on/off and shifting in/out of park multiple times before the vehicle could be turned off completely. Once the vehicle was finally turned off completely, I wasn't able to drive it for a few weeks for fear of not being able to turn off the vehicle at work/stores/etc., or for fear of being stranded when the battery drains. This is a serious safety issue that effectively makes the vehicle unusable. After researching the problem, it was found that this is a known issue to GM for multiple models and years of vehicles per service bulletin 19-na-206. Based on my experience, however, the initially intermittent nature of this problem quickly turns into a permanent, disabling problem. In addition, a more permanent solution needs to be provided than what's listed on the service bulletin: (a) scraping deposits off the electrical contacts with your thumb 50 times to see if that works, (B) installing a jumper to see if that works, or (C) replacing the shifter control assembly. My concern is that if the design of the new assembly is the same, the problem will reappear in a few years with the replacement assembly; all are just temporary stop gap measures. A real fix that prevents the corrosion/deposits is needed, and a recall should be issued.

Driving and my car wouldn't stop because my stablitrak and ABS system malfunction and now the dealer is saying I need a vacuum pump and throttle change. This is a know issues in the GM cars just seen on google that a global letter was sent out Aug of 2019 about this issues but I never received it. These cars should be recalled and we should be given our money back. I have 2017 Chevy Malibu and I feel this premeditated murder because they know it's a issue and I could have lost my life July 30 2020 at 959pm

The Chevy Malibu has a problem with the shifter. When you put the vehicle in park it will say on the driver information panel to shift to park even though it is in park. The vehicle will not shut off. The vehicle is stationary when it happens. GM needs to fix it. Because it is a safety and the car will not shut off until to sensor is told to put it in park.

- Midland, MI, USA

Dic intermittently displays "shift to park" when shutting down engine beginning at about 30,000 miles. Dealership states this is not covered by power train warranty. Well known problem with two tsbs issued but no recall. Research shows owners paying $200 to $700 for repairs when out of warranty. I replaced "park" switch with pn: 653-D2hw-bl221H at 31,000 miles. $12 including shipping. Why would they recall when it's a "cash cow" for Chevrolet.
