This issue has happened twice. The first time it happened it was in motion on the highway and a message appeared on the dashboard, "engine power is reduced." It began deaccelerating from 75 mph to 20 mph. I had to quickly pull over the car to the side of the highway and I cut the car off. I truned the car back on and the message went away. The second time it occurred the vehicle was in motion on the highway again when the engine light came on in the dashboard with a message, "engine power is reduced." The car was going 80 mph when the message came on this time. I reached out to the Chevrolet dealership and they confirmed there was not a recall. I did some research on the issue and discovered that there have been other people with the same vehicle who have experienced the same issue.

When I shift my car to park and turn off the ignition, I receive a message stating "shift to park". it keeps my car in the accessory start position thereby running the battery down if I cannot get it to recognize that the car is in park and the engine is shut off. This has been an intermittent, ongoing problem for about 2 weeks. I contacted the local GM dealer about this but there is no recall.

"steering assistance reduced drive with care" warning appears on dash right before I'm going to accelerate after being stopped.

- Riverside, CA, USA

When driving at auto stop, when beginning to accelerate, car acts like it shut off and says steering assist reduced drive with care. I noticed the battery voltage goes down to 11.0 V. also the radio screen flickers black. This has happened multiple times in multiple days.

Vehicle would indicate/notify to shift to park even though vehicle indeed in was in park not allowing you to complete turn car off. Car would remain in ancillary mode.

- Blue Island, IL, USA

Driving down the interstate at 70 mph and car states reduced power mode. I could only go 20 mph and try to cross 4 lanes of a highway during rush hour. I almost killed several people including myself. I have read this is happening to other people and I want it fixed.

I just submitted a complaint about this issue, it has happened more times than I can count so I'm submitting again. I have told people at Chevy about this problem twice, when I went in for oil changes/maintenance. I have only gone to Chevy for any type of maintenance because I want my car to be taken care of by people that should know everything about it. That's why I'm extremely disappointed that I have purchased this car brand new, taken the best care of it, only taken it to Chevy even though it's obviously more expensive, but still no one has helped me with this problem or explained why it's happening. It's been over a year since I've reported the problem, and now I'm worried I may have too many miles for this problem to be taken care of. When I put my car in park, it doesn't always recognize it's in park. This means that my car will not turn off, and I can't leave my car until it recognizes it's in park. I've found that this problem will almost always happen if I try to turn off my car engine "too soon". I have to wait about a minute before I can turn off my engine, or I risk my car not recognizing it's in park. If this happens, sometimes I only have to press on my break. Other times I have to turn the engine back on, drive, and wait before trying to turn my engine off again. This can take multiple tries, multiple minutes worth of just trying to park my car and turn it off. I do commute about 70 miles round trip for work each day (Monday-Friday), so I use my car quite a bit, but like I mentioned I bought this car brand new and take the best care of it. I do not cut any corners because I do drive it a lot. I have never been in an accident, had a ticket, I drive very safely. There is no reason, my car should have any problems simply parking after having it for less than 2 years.

When I put my car in park, if I turn off my engine after a few seconds of sitting in park, sometimes my car doesn't recognize it's in park. My car will tell me to put it in park before I'm able to turn off my car. Sometimes I just have to step on my break again, and it will recognize it's in park. Sometimes I have to turn my engine back on and wait a minute or two. Sometimes I have to put my car in drive again before putting it in park, waiting a couple minutes, and then it finally recognizes it's in park. I have not figured out what works best, except for just waiting a little bit before trying to turn off my engine. If I can't get my car to recognize it's in park, I can't leave my car because the battery will not turn off until it recognizes it's in park. It can be very frustrating. When I brought my car in for an oil change at Chevy, I mentioned this problem to Chevy, thinking maybe something was loose. They said they've heard about this problem before, and said they could fix it. When I came back for my next oil change, I again needed to mention this problem, because the problem goes away for a little but comes back. Again, they said they could fix it, but it still happens. They are aware of this problem, it's happening to multiple Chevy customers, but no one has been able to tell me what the problem is or how to fix it.

It takes a while for the car to accelerate on highways or streets. With my foot to the floor of the accelerator, it gets to 20 mph in about 15-20 seconds which prevents any pickup. Only thing that helps the pickup is when I use octane booster in the tank and it'll drive as it should with pickup for a very short period (5 miles) otherwise the acceleration is extremely laggy with no pickup.

While driving my car started to say driving assistance off please drive with care then it acts like it's going to turn off. Now its sying

My trunk was flooded for no reason. Plus when I shift to park it says shift to park when I already have. My sister just gave me this car with only 14,000 miles and two problems. The trunk mat is getting white mold. This car sat for 6 months.

- Woodridge, IL, USA

Sometimes when I park, even though vehicle is clearly in park, I receive a message on the dash that I need to "shift to park". this is a known problem with many GM vehicles and if you leave the car like this, it will drain your battery. I have to repeatedly shift out of park and back in to get the message to go away. I don't know what I will do when this stops working. The date of "when did this happen?" is the most recent, but it has happened several times.

I bought the 2017 Malibu premeir with 5 miles on it in Sept 2017 and have had problems from the start. 2018 while riding on interstate my car just stopped went straight to dealer they said nothing was wrong after keeping car for 2 days. Went to leave dealer ship and car stopped in parking lot, sensors went out on front of car. Fixed 2019.next my car kept getting water in tire well and I went to dealer and they told me it was not a recall. So I kept bailing out water and parking in garages. Three months later recall.I was without car for 4 weeks as carpet, headliner and complete trunk carpet and molding had to be replaced because of mold,2020.my car tells me to shift to park when car is in park and I have to turn car off and on nd move from D to P to get it to work. Tells me when 'I'm driving no key found in vehicle or put key fob in pocket.,yesterday Sept 5.2020 went to get inspection sticker and attendent told me you have no backup lights. Never noticed it. So went to auto zone and bought light and went to mechanic shop to have put in. While sitting in car went to open sunroof, it wasn't working and it had been months since I remember opening it, so 'I'm reading owners manual and went to turn on map lights. No lights. So mechanic comes and says there is nothing wrong with your bulbs. Let me check fuses, usually when both light go out at same time its a fuse problem told him about sun roof and map light, he checked every fuse inside and out. There is nothing wrong with my fuses or the lights. They just wont come on. Neither will sunroof open. My car has 56000 miles on it and I've had problems since 25000 miles. I thought I would keep this car for at least ten years as it cost a pretty penny for the car

When shift car into park and go to turn car off a message pops up that car needs to be in park even though it shows it is in park. Doesn't happen all the time but happens and you have to turn car on and off and shift a few times before it will recognize it is in park.

- Cleveland, TN, USA

A dashboard notice to 'shift to park' pops up after putting the car into park and attempting to turn it off. The car does not register that the car has already been stopped and switched to park.

The nuts used to fasten 3rd brake light are not locking nuts therefor loosen causing the 3rd break light to filter to loosen and break. This also causes flooding in the trunk of the vehicle. I had 2 inches of water in the spare tire compartment along with a soaked trunk which caused a terrible smell. You will see in the pictures I have tried to repair the broken plastic on the break light with an epoxy mix. Replacement would be better. I think breakage is caused because the nuts loosen.

When I get to a stop light the auto stop activates. When the car goes to turn back on it trips up and dies completely. The steering wheel locks and the car won't turn back on. I have to wait for about 15 minutes until the car will turn on again. It doesn't happen every time. It usually happens when I am at a red light for longer than 30 seconds.
