While I was pulling into a parking spot, my 2016 Chevrolet Malibu suddenly accelerated without any prior warning. The sudden unintended acceleration caused the vehicle to somehow jump the curb, hit a sign, and go airborne landing on two park cars which, resulted in damage to the front end and passenger side fender, front grill, left tire and other parts. The car was leaning to one side and I had to pry open the driver side door to get out. One of the other cars was totaled and the other had hood damage. It took two tow trucks to remove the car off of the other cars, it was towed to a repair shop and repaired by my insurance company but I no longer have possession of it. I was too terrified of it to keep it. It is still unknown what caused the vehicle to malfunction.

I have taken my vehicle multiple time and still the problem not fixed. Had a reduced engine problem at first and now there's a message that comes Battery charging system. replaced battery twice and replaced the alternator twice. I spent at least $2,000 trying to get my car fixed. The Charging system battery, the battery drains until it goes dead. The car stopped on a busy interstate with me in it. I had to wait on a tow truck,(while working) on the interstate while watching the trucks and cars pass by hoping that they wont hit me. After charging the battery and putting it back into the car the battery light comes on. and while the car is crank and sitting still the battery charging light comes on. the battery quickly looses power. GM realyl need to do a recall on these vehicles. Please help.

Car suddenly lost power slowing to 20mph on highway slowing to the point I was an obstacle in the lane so had to abruptly drive on to shoulder and out of traffic to prevent a collision from behind me as I had a close call. Car showed reduced engine power message. I wait until late at night when there was no traffic to drive the car home safely. The next day I had code read and it was a P2138. From what I have now learned online this is a wide spread problem that GM is very aware of.

I have a 2016 Chevrolet Malibu and while driving on the highway, my engine light came on and my speed decelerated from 65 mph to 40. I took my car for a diagnostic test and the results were Trouble Codes: P2138, U0401-71 and C0242-00. I have done my research and from what I have found so far, is that several people have made Youtube videos about these codes, complaints and complaints on this website as well, and it has come to my understanding, that if enough people complain that this can be a safety issue, then maybe the "POWERS THAT BE", will help with this issue and possibly resolve it. This is and can be dangerous for an individual to drive at the average speed on most U.S. highways, 65, and they decelerate without warning down to 40 mph. I'm not sure why anyone does not se the dangers in this situation, especially with other motorists on the road driving at speeds of up to 70 mph, sometimes 75 mph. If I have vehicles behind me driving 65 or more and my vehicle decides to decelerate because of a sensor failure, the vehicle behind me is not going to know that there is a problem and may not have enough time to react before causing an accident. I am adding my concern not only to many individuals who have reported the same or similar experience , but in hopes that this issue would gain more attention.

The first incident happen on 2/27/2019. I was existing the highway on highway 75 in Kennesaw, Georgia going north bound and coming off on Barrett Parkway. As I exited the highway my brakes was stuck and my brakes wouldn't press. I panicked because I was going at least 60 mph trying to slow down to get on the exit with semi trucks in the front and in the back, because I was a little skilled with cars I down shifted my car and stepped on my emergency brakes and ran the car off the road into the grass. I towed the car to my mechanic in Hiram, GA. (Donnie's Automotive) to have him work on the issue as I wasn't sure what was going on. I got my car back on 3/1/2019. Now the next incident happen on 8/16/21 my engine decreased and my car wouldn't accelerate more than 40 mph. Took it to my mechanic again and it was the throttle sensor. Now the most recent incident happen 6/12/21 where my brakes failed to pressed again and bc I was aware of this incident happening in 2019 I did the same thing and ran my car off the road. My kids were scared. Now all these issues have been a issue with Chevy and they even had a class action lawsuit against them for the throttle sensor issue. My car wasn't part of the recall but my car has suffered the same issues they've know about for years. I called Thornton Road chevy and they told me it's nothing they can do. I've also emailed the CEO and all others for CHEVY. I want chevy to repair my car before this car KILLS ME OR MY KIDS.

Okay so I’ve been getting this “engine power reduced” sign on my dash off and on for the past half year. I take it to the shops to get fix. They do some temporary fix and it’s good for a month or two then the problem persists. I’ve dodged very close attempts at death due to this. Driving on the highway or interstate (at respected speed) and then suddenly the car just slows down abruptly. Scared me half to death due to the fact that I’m on busy roadways. I’ve managed to get over on the shoulder or nearest exit without collision. One time is happened on a turnpike and I came like inches away from hitting the wall. For all of those times I was able to cut the engine off for a bit and then worked good enough to get home or to a shop. For this last time though was the worst. I was in the turning lane of busy intersection and the car like pulled as I was making the turn and then it just cut off. Causing cars to have to swerve around me which could’ve caused other incidents. I turned the car on and off many times but I still could not regain normal speed. It wouldn’t pass 18 then 27 and finally 36. I had to ride with the hazards on and what was supposed to be a 20 minute drive ended up being a 60 minute drive (after sitting in a parking lot for hours). I have lost one job due to the fact that I had to call off so many days. I have lost privileges at other jobs that effects how I’m able to provide for my family. So this is really hitting me hard. Most mechanics seem to know what the problem is but no one has actually fixed it directly. I hope GM does something about this please. This is my first and only car and I’m proud of it, but far as the performance. It’s a death trap. That’s why I don’t allow anyone to ride with me or drive it, because I just never know. I would rather be in the car when something bad happens than someone else. It’s feels like a stick shift/like a sticky clutch or something of that nature when I drive.I don’t know much about cars but that’s not right

When I go to shut the engine off it sometime still runs and after pressing the off button I have to go thru this off cycle many times before everything shuts down. The screen behind the steering wheel says to put it in "park" but it is already in "park". This could be a real safety problem because someone could drive the car into the garage, shut the door and not even know the engine is running!

When I go into park and turn off my car I get a “Shift to park” message. This happens numerous times a day. Sometimes the light turns off after a few minutes by itself. Most of the time I have to wiggle the shifter or turn the car back on and go from another gear such as drive to park. I have read that this is a common issue amongst this make and model.

My vehicle, a 2016 Chevy Malibu, has started receiving the *known* GM "Shift to Park" error message. This error message occurs when the vehicle is in park, but the driver information center (in the dashboard) alerts to "Shift to Park" before you can shut off the vehicle. If you try to exit the vehicle with the error message, all electronic systems (screen, lights, dash, etc) will stay on, draining down the car battery, putting me at risk of being stranded due to a known issue in my car and/or me having to leave my car running, putting my car at risk of being broken into, stolen, or worse. I have wasted countless hours already, in the very short time the error has occurred, having to shift out of park, reverse, drive, back into park, and keep trying over and over and over and over and over and over and over, until it finally might register. One evening, it took over two hours for this to work. This is a HUGE risk to me, especially in the city I live in, as a single woman. Furthermore, the fact that GM and NHTSA have a service bulletin on this, and it is a *known* issue in my year, make, and model, on top of the thousands and thousands of online forums reporting this same issue, tells me that this is much, much larger than anyone (especially GM) would like to admit, and that my car needs to be included in the recall for this.

The 3rd brake light broke(high mount stop lamp) which caused water leakage into the trunk and filled the compartment where the spare tire goes.

Every month my car will randomly say engine power reduced and will go no higher than 30mph. Which has happened on the highway and is super dangerous! I have seen many reports of the same problem but nothing being done about it. I took it to the dealership I got it from and I paid $100 dollars for diagnostics and the mechanic said the car computer needed updated...alright, the next day the message came back up and car couldn’t go higher than 30. I haven’t had this car for a year, and the shocks have popping noises, and whenever I put the car in park a message will appear saying shift car to park. And I have to literally roughly giggle the lever for it to read it’s in park or my car won’t turn off. I truly love this car but it has to many issues that shouldn’t be happening.

A power reduced engine light came on and slowed the car down to 20 miles per hour very abruptly, it was very dangerous. It keeps doing this, the engine light turns off so it can't be detected, and now we can't take it into a dealership because its out of warranty.

WHILE STATIONARY, AND READY TO SHUT OFF CAR, GET A MESSAGE TO SHIFT THE CAR TO PARK BUT IT ALREADY IS IN PARK. CAR WILL NOT SHUT OFF. HAVE TO KEEP MESSING WITH SHIFTER SEVERAL TIMES BEFORE CAN FINALLY TURN CAR OFF. THIS HAPPENED CONSTANTLY. TOOK CAR TO DEALER, PROBLEM DIAGNOSED AS TRANSMISSION SHIFTER CONTROL PROBLEM AND I HAD TO PAY $445.08 TO FIX. SUPPOSEDLY CHEVROLET RECOGNIZED THE PROBLEM IN JULY 2019 BEFORE THIS STARTED HAPPENING TO ME AND ISSUED A TECHNICAL SERVICE BULLETIN (I THINK NO. 18-NA-297) BUT THERE WAS NO RECALL DONE. MY POINT IS, IN CASE OF AN ACCIDENT AND POSSIBILITY OF FIRE, IT IS A SAFETY PROBLEM IF THE CAR CANNOT BE TURNED OFF QUICKLY. SO WHY DIDN'T THIS PROBLEM DESERVE TO MERIT A RECALL AND FREE REPAIRS?
