Vehicle ECM fails when accelerating. Loses power/shuts down. Cannot enter freeways, pass, or perform other maneuvers requiring sudden increase power demands. Ecm fails to record incident. Every time. Every day. Updated ECM software does not work. Reset check engine mode shuts down other vehicle functions. Have been too close to being run off the interstate, hit when entering from on-ramp, rear-ended in heavy traffic. The federal safety agency does not investigate because death and injury cannot be linked to failures because the module does not record issues/failures. There is no fix. Every day you get in your car and wonder if today is the day you die because your vehicle failed to perform at a critical moment. Now vehicle shut downs while driving on level surfaces, at constant speed, with no additional demands. Am installing cams to record traffic conditions and vehicle warnings displayed on dash since ECM does not record failures. I believe a thorough investigation into all rear end collisions involving 2018 malibus should be conducted since the vital link, the ECM record, has been disabled by manufacturer.

Shift to park warning when exiting vehicle when the vehicle is in park and engine is off
My 2018 chevrolet malibu has a problem when shifting from drive into park. The message on my dash says " shift to park " even though it is in park. And you can not shut off the engine. You can try shifting it back into drive or low and then go back to park but we get the same message " shift to park " and again even though it is in park, you can not shut off the engine. Isn't this a dangerous situation ?
When vehicle is shifted into park and the vehicle is turned off, "shift to park" displays on the vehicles screen and will not allow the vehicle to fully turn off. In order to have the light turn off, sometimes you have to wiggle the gear shift around whereas sometimes you have to press the start button and shift between gears a few times.
On, july 15, 2020 my car gave a "shift to park"message on the dash after I had placed my car in park. I continued to have this error for the next few days, I made an appointment with my dealership. The issue is you are stranded in your car until you can wiggle the gear shift into place sometimes upto 20 minutes. The vehicle is stationary and in the park gear, however the car never turns off. The start button is illuminated amber and dings for assistance. This can possibly drain a battery. The dealership charged $518.00 to repair a known gm issue. Gm customer service admitted to it and so did the service advisor, I received a "new" improved version of transmission control assembly. Probably should be a recall or class action suit.

Reduced engine power notification in mid drive on freeway causing car to come to low speed in a 70 MPH heavy traffic flow. Multiple vehicles swerve to avoid contact (accident). Unable to pull over quickly as it happened out of no where. Unable to accelerate.
Car shut off in the middle of driving. With no engine light on. Engine light randomly comes on every other week. Tps doesn't function properly. Idles high some days then drives normally. Sensors was changed engine light comes back on a week later with same code vacuum sensor, maf,
Shift to park message displays once car is placed in park. Car will not completely turn off once in park and ignition is shut off
When putting vehicle into park vehicle will give message saying that the vehicle is not in park when it clearly is in park. I sometimes have to turn the vehicle off or mess with the gear shift for a little while for the message to finally go because the vehicle itself will not power off until the message goes away. This could be a safety issue and chevy needs to address this asap! These are brand new cars that are doing this and there shouldn't be any issues with it being a brand new car. They need to make it a service bulltin and or recall.
Auto stop just stoped working also when I put it on park it shows 'shift to park' but the vehicle is on park already.
Vehicle transmission not entering in parking , causing vehicle to move forward or back if put on parking. This could cause accident and serious injuries . This might be a sensor or and electrical failure in the gear selector, because if you wiggle the selector sometimes it will go away. Vehicle will show message vehicle not in parking.
Since july 2019 my vehicle has continually shown a check engine light with the message, power engine reduced on the dashboard. When this occurs, the rpms increase drastically and vehicle can not go over 30 MPH. This has happened on highways and main roads. It is very dangerous because I can be going 65 MPH on the highway and all of a sudden it drops down to 30mph. This has almost caused accidents multiple times. I have attached multiple service records where I have had the vehicle worked on, but yet the issue still occurs at anytime. The vehicle is very unsafe to drive. There has been recalls on this issue and although he dealerships say they fixed it for my vehicle, it still occurs. I have contacted gm and have not gotten an answer or had the problem resolved and it has been over a month I have been working with them. There last reasoning for not giving me a resolution was because they were waiting on service records, yet I called the dealerships and had the service records in less than an hour.
Car says shift to park on dash monitor when car gear shift is definitely in park. Car was stationary in a parking lot after driving.
My transmission has had multiple repairs since I've gotten my vehicle. The vehicle had to go in for several months while they fixed the transmission but once I got it back it instantly had another transmission issue. It has also had the shifter replaced, which is another transmission issue.
While driving on the freeway at speeds of up to 80 MPH at random times the car will suddenly slow itself down to 20 MPH and the dash will message that engine power is reduced. It's a serious problem that is dangerous to not only the people in the vehicle but all other vehicles on the road also.
Vehicle experienced reduced power before learning about and addressing the recall. A couple of months following my vehicle began to shut off and restart while giving various error messages. This occurred while going speeds less than 35 MPH and while stopped. The dealership determined it was a faulty battery censor and was not covered under the warranty. I have had the part replaced and did not experience any issues for roughly 2 weeks. My vehicle today gave a error message that engine power is reduced and the check engine light is on. It is also hesitating/jumping when switching from drive to either reverse or park.
Engine power is reduced warning and check engine light anti skid warnings come on.
Check engine light, traction control light both on, reduced engine power, speed and transmission shifting limited, cant go pass 3 gear. Started randomly on numerous occasion while driving. Very dangerous.
Check engine light and reduced engine power vehicle won't accelerate on highway in traffic
I was driving down the interstate doing 74 miles an hour when all of a sudden the car jerked and started slowing down. The display screen showed a messaging saying engine power reduced. I pulled over on the shoulder because it wouldn't let me accelerate and had slowed the car down to 50 MPH. I sat there for a minute and was going to try to drive on the shoulder to the next exit. When I started the car the message was no longer there but the check engine light was still on. The car has done this more than 10 times since this day.
Accelerator pedal position sensor correlation (p2138). Engine power reduced
When I put my car into park and go to turn off the vehicle, it throws a "shift to park" code on the dash when my car clearly is in park. I took it up to a chevy dealership, and they said that there were quite a few vehicles that were having the same issues. They told me that there were two options as to what it could be, so I paid for the first option that gm recommended they do first. That did not fix the issue. Now, I'm being told that I have to bring it back up to the chevy dealership and pay another chunk of change just to get it fixed. It is quite frustrating, as it takes a while for me to get my car to register that it is in park, and if I don't, then it drains my battery because the car won't fully shut off. Extremely frustrating and annoying.
When shifting my car into park, it will clearly be in park, yet when I shut off the engine, I get an error message "shift to park". This has happened multiple times in the last month, and now just last night, it took me 15 minutes to get the car to stop the message. Its becoming irritating! If you do not try to fix the issue once the car is turned off, then you're battery will eventually be drained. I contacted the local chevy dealer and they say that there are other car owners complaining about it. I am waiting for a replacement part, but since gm was on strike, my wait is longer.
When the car is shifted to park, the car does not register that it is in park. The car then has to be turned on, the shifter moved back to drive, and then back to park again. The car then has to be shut off again, and if I am lucky, the message goes away. If it does not, I have to repeat this process over and over again until the message does go away. This is a common issue specifically in chevrolet malibus dating back to the 2016 model. This should be a recall issue given that it is widespread and the fact the gm makes people pay to repair their faulty parts out of warranty is ridiculous.

On chevy malibus when you put the vehicle in park and shut it off, anywhere, and the vehicle is stationary, a message will pop up "shift to park" but it is already in park. The car will not lock and battery will die down if you can't get it to sense that the car is in park. You have to mess around with the shifter until it will recognize it is in "park". Which can take up to 20 minutes or not at all. After researching online I have found that many, many other chevy malibu owners are dealing with this same issue and all agree this should be a recall. This can be a very frustrating issue when you are trying to get to work on time but can't get your' car to shut off and if it wont by the end of the day your' battery is dead. There are many complaints online about this. Ultimately the car will not sense that it is in park which causes the car to not lock among other issues. My car is only a year old and doing this. It seems chevy knows of the issue but wont do much to fix it.
Car not wanting to get up to speed when pulling onto busy roadway. Feels like it creeps up to speed slowly feels like it is not in accurate gear.
