2017 Chevrolet Malibu acceleration complaints
Page 3 of 6: complaints 41 to 70 of 135, newest first, as owners wrote them.
The vehicle constantly reduces speed when there are no issues with weather or any other issues on the road. This issues can potentially be fatal. I have had it checked and the diagnostic machine says it’s sensor issue that was reported for recall but my car was not part of the said recall. The car completely shuts off and will turn on by itself after 10 minutes. Uncertain what to do
While merging into traffic my 2017 Malibu's power reduced (reduced power indicator appeared) which resulted in my inability to control the speed/acceleration. I've had two additional incidents. Very unsafe deficiency.

On January 2022, Wednesday the 19th. My husband, myself and our two daughters 12 & 4 are on the Northbound freeway 99 in the far-right lane and the car pops up with the warning “Engine Power Reduce” and then proceeded to decline in speed from 70 MPH to 15 Mph almost instantly almost causing an accident. WE all were so shaken up! Had we been in front of a big rig we would have been crush from the backseat as fast as the speed declined. WE just bought this vehicle 5 months ago no more than 10K miles on it. The dealership says its not there problem to contact GM. Nobody will help this is a death trap vehicle. There are already multiple class action lawsuits about this issue and the vehicle. We are simply being told to buy a newer vehicle rather then someone taking ownership of this issue. This is a deadly issue and why there is not a recall is outrageous, There are cars out there that are capable of causing a deadly crash and killing thousands of people and everyone is turning there head when the consumers are reaching out for help.
Low Engine Power message appears , my driving speed dismished I was on the highway driving and the light appeared, I also needed some fuel, but I did eventually stop added gas engine light disappeared but it eventually reappeared again and has remained with full tank of gas
Driving on highway at about 65 mph on family trip to Delaware. . Car suddenly gave reduced acceleration error and speed started declining while in traffic. No warning.checked chevron app on phone and it did not see anything wrong. There was NO check engine or anything. Got to a dealer and they said it was probably a sensor for gas pedal. 5 days later driving home to Georgia from trip on highway around same rate of speed. No warning . The check engine light and reduced engine power warning message came on. This time the Chevrolet app notified me of trouble and said I needed the car seen within a day. .Got to a dealer and now they say they think it may be the cam shaft based on the code but they cannot replicate issue. I took a photo of the alert from the second incident . Car has about 46,000 miles and is well maintained . Our safety was at risk both times but especially the first time as we were in traffic and speed declined .
Throttle Position Sensor is falfuctioning. Class action law suit against this already. Chevy Malibu Class Action Lawsuit is Hutchinson v. General Motors LLC, Case No. 8:19-cv-01551, in the U.S. District Court for the District of Maryland. Vehicle decelerates at highway speeds down to 20 mph and engine power reduce comes across the screen. Has almost caused me to be in three accidents. Need to recall all malibus and have this part replaced before someone is killed.
I was driving on the interstate and the dashboard said Engine loss of power. It was very dangerous because it reduced my speed drastically in the middle of traffic! My whole family was in the car and this is the 3rd time this has happened to me since purchasing the car. And now my check engine light is on. I don’t understand why this happens, but defective parts that create this problem put our lives in danger! Why is there not a recall on this? This is very important and should be fixed immediately! I almost wasn’t here to write this so please show me and other owners of these cars in these model years how to not die in your vehicles please?!
This is my second complaint and possibly the last, in my first complaint I reported the problem with the car after showing a stability track warning light then slowing to a 20 MPH velocity in a snow storm , then my adventure with the vacuum pump shattering , thus no vacuum, no brakes, on the highway going 70 MPH. After that scare , it had a crank no start problem. That's where I ended my first complaint . Part 2, I collected my stimulus money and had my 2017 chevy malibu ls towed to a chevy dealership. After the service manager asked me for the spare fob, I asked him could that be the problem the batteries went low and the fob keys had to be re-programed. He stated probably, I went home hoping it would be something minor. 3 weeks later I get a call from the service manager that he wanted to go through the diagnostic inspection results with me, I ask him was it something minor, he said we haven't been able to work on the crank, no start problem cause you have low compression on one of you engine cylinders you need a new engine, that's not minor 72,365 miles, new engine , estimate $8,224.80. Still paying the bank for it..this generation malibu's are not even close to good. I own a 1994 chevrolet silverado with 135,000 miles bought it brand new, runs great, the cost cutting is being sacrificed for quality, and us consumers are getting the low end.
Speed reduced on freeway to 20mph, speed reduced warning with check engine light on.
As we were going 75mph down the highway the vehicle started deaccelerating with the check engine light with the following message appearing on the screen 'engine power reduced' we had to quickly pull over to the side of the road to avoid having a wreck. After shutting the car off for a little bit the message disappeared. After looking into this there a multiple people with the same car and same issues, but no recall or investigation has been started.
As I was turning left from a stop light accelerating on the interstate on ramp from 20 to 40 MPH (approximately) the "check engine light" came on, the engine slowed down and lost power, and "traction control light" came on even though it was not engaged. My speed control disengaged and would not work on cruise control. When I pulled in my garage (approximately 8 mi) shut the engine off and restarted all warning lights cleared and everything reset. This condition happened to me twicw in the same day. The sudeen loss of power is a serious safety issue.
I purchased this vehicle for my son in january 2017. 3/27/2021, he was driving it and lost power on the interstate. The vehicle would not go over 25 miles an hour. He had to stop on the side of the road and let it sit for a while then restart it. It happened 4 additional times within 30 minutes.
Car keeps going into reduce power mode 2 to 3 times a day happens on the highway constantly very dangerous will never purchase another chevy agian
Car went into low power mode and wouldn't drive over the speed of 15-20 miles an hour.
Check engine light and reduced power message diaplayed.
I was on the highway trying to pass another car, but while I stepped on the accelerator pedal the engine power reduce with engine light came on and my car started loosing it's speed. I restarted the car and the engine light stayed on and now my remote start(fob) will not start. It attemps to start but the engine willnot turn over.
Vehicle reduces power at random times. Without being signaled to do so. Has happened on the high way and streets
The reduced engine power light is continuing to appear. I took it to my gm dealer and they told me they can't fix it. This is a safety concern. Dropping from 60 MPH to 30 MPH on the freeway/highway is not safe.
I was driving on the street when my engine power is reduced notification came up on my dash board. My engine light also came on. I was driving about 45mph when the light came on and it reduced my speed to 20mph. I was able to drive it home at the 20mph speed. I parked it overnight and checked on it the next morning. When starting my car the next day the engine power is reduced light was still on. I was looking online and others are having the same issue. What is going on. I need help
My car will say "engine power reduced" and it will not let me accelerate after it happens. After I shut my car off and back on, the engine light and traction control light comes on.
Ii bought my 2017 chevrolet malibu ls in august of 2017, in january of 2018 my first engine light warning came on with message "shift to park" came on when the car was already in park. I moved to denver, co in june of 2018 , during my long while driving through the rockies the check engine light came on showing "stability track issues. In november 2018 while my family was driving home in a snow storm yet another engine light showing "engine powewr reduced" the car went from a 45 MPH drive on the freeway because of heavy snow to almost 20 MPH too slow for freeway speeds even in snow. I took it to the chevy dealership they said it was a dirty speed sensor. While driving on the highway at 70 MPH I was reaching the end of the freeway when the car completely shut off, I reacted by hitting my brakes but the pedal was hard as a rock, I looked up and I was fastly approaching an intersection so I used the emergency brake got on the riight dirt shoulder, and was able to slow it down to about 35 MPH before reaching the intersection where I took a sharp right turn to avoid hitiing cars in front of me and spun out. The car ishowed a message "no remote detected: it would crank but not start . Being that the car warrenty was already expired I had it towed to a local mechanics shop where they discovered a code reading "brake booster sensor" they discovered a shattered vacuum pump. I got it replaced with a new one as well as the brake sensor. I still haven't been able to start it. Because of covid-19 and my financial situation I have not taken it to a dealership. I am saving to have it towed there and hopefully repairing it but I'm sure it's not going to be wallet friendly. We were excited when we bought our first new car it didn't last long. Now hopefully a recall and some justice for us hard working people that want only a reliable car with no hidden repair surprises.
While driving at interstate speeds the vehicle has now flashed warning (reduced engine speed) and completely dropped vehicle below 40 MPH. This has happened multiple times over the last week with possible results of getting in a crash. I safely moved vehicle to shoulder and turned off and restarted vehicle. The issued resolved itself the first time then a week later it happened again with no fix after the shut off and restart. I have read forums on this issue with 2016-2018 models. I am looking to see if there is a safety recall to get the defective part fixed from an authorized chevy dealership.
While I was at the highway I was trying to pass another car, but while I stepped on the accelerator pedal. Engine power reduce with engine light on came up with code p2138 and my car started loosing it's speed. Its not the first time it happens , it has happened a few times. This code is getting annoying and I have seen many cases with other customers having the same issue and there's no solving to this problem.
When driving my car, it suddenly stops in the middle of the freeway and displays a 'loss engine power code'. I noticed that quite a bit of other malibu owners have been having this same issue
Reduced speed engine problem will reduce speed while driving
Reduced engine power warning 12/29/20 plus numerous occurrences in 2019 while driving on the highway; vehicle slows to 40mph without warning shift to park warning when vehicle already in park, can't shut off vehicle until it recognizes park, often taking upwards of 10 minutes of repeated shifting stabilitrack sensor warning and loss of cruise control, at highway speeds
Started last november 2019 I was driving to work and suddenly my check engine light came on and then a engine power reduce comes on and my car starts to slow down. Took to chevy and was told they could not test the diagnostic because my check engine light was no longer on. Fast forward to this september 2020 and it started up again and has been on and off since. This is very dangerous as it happens at any point im driving whether it's on the freeway or small road. I'm having to pull over and turn my car off! I have teenage daughters and 2 small boys that I have in my car when this happens and it's very scary and dangerous! So today december 15, 2020 I took it back to chevy and getting it checked. I was told it could take up to 5 days and I'm really hoping this is a factory recall due to the safety of this happening while driving and driving at fast speed on the freeway!
While driving the car down the road a message displayed saying "engine power is reduced" and I could not drive the car over 20 miles per hour. This thankfully occurred while I was driving through a residential neighborhood so I was able to safely park my car. Through research there is a known defect with a faulty accelerator sensor that causes this. It is the first time this has happened since getting the vehicle brand new in 2017. This is scary because it was instant and I could have been on the freeway when this occurred.
