What 687 owners told NHTSA about the 2017 Chevrolet Malibu Eco

bought this kind of new and while still under warranty reduced power engine light came on & engine is reduced to 20 mph have to pull over shut it off wait a few minutes and start it back up and then it will be all right for a while we called dealer made an appointment but by the time the appointment came around the light had gone out they said the light needs to be on in order for them to diagnose the problem the light goes off after about 50 miles after this happens so we could never get it into them within that 50 mile time frame we gave up after a while now it's happening more often and I hear that maybe a class action suit coming they don't seem to be able to solve the problem. we still own this 2017 Chevy Malibu and it is still doing it today.

I was driving at 70 MPH on the freeway when off a sudden my car haulted back and said engine power reduced. I had my kids in the car and traffic behind me when my car went into an auto decline in MPH reaching 30 MPH before I could quickly pull over. I called the company I bought my car at the next day. They told me I needed an inspection but my check engine light only stayed on overnight and was off by the time I went in. In the last year this has happened over 10x. It’s manageable but incredibly dangerous if going at a fast speed. The weird part is if you turn your car off for 1-2 minutes, you turn it back on the there is no longer a power reduction and all is back to normal.

2017 Chevy Malibu over 15 times this happens since we owned buying it brand new it has "Reduced Engine Power" error come on and the car can't accelerate over 30 miles per hour. This is a continued problem all the time and very dangerous when we are on the tollway that has a 70-mph speed limit, and you can't get the car to over 30 mph. This same problem happens on our 2018 Chevy Malibu over 5 times since we owned it too and it's getting worse! This is extremely dangerous and takes you a long time to get home when you can only go 30 mph or less because of the "Reduced Engine Power" Limit. Same 2017 Chevy Malibu also has the "Shift to Park" Error so we can't shut off the engine because the car won't go into park, you have to back up and keep trying to get the shifter to let you put into park if you're lucky it will finally after many shifting attempts back and forth to get rid of the error so you can shut off the engine to exit your car. GM should be responsible for a recall on these two very important errors that these Chevy Malibu cars are having on both of the problems are very dangerous "Reduced Engine Speed" and "Shift to Park" can't shut off the engine is dangerous.

“Engine power reduce” error on dash as well as check engine light. Driving on highway at fast speeds when this message displayed and my cars mph dropped to 30mph. I’ve had this issue fixed once already with the dealership and it turned out to be the sensor throttle or something with the pedal. Yet, 5 months later, I am having the SAME problem. This is very unsafe

Engine light comes on, reduced engine power message displays. Have had numerous issues with this. Replaced gas pedal, was fine for a year. The issue is back. Why has'nt NHTSA acted on this well known issue? Car goes from 70 to 40 on the highway. GM has done nothing to fix the problem! First started around 10,000 Miles.

My wife has had this happen three times now in her Malibu: she's driving on the interstate and the engine suddenly loses power. A light comes on that says "engine low power mode," and the check engine light comes on. She has to complete the journey at low speed (less than 30 mph). Once she gets home, shuts the car off, opens the door, and when she comes back and restarts it 10 minutes later, it's fine. Today, it didn't shut the check engine life off, so we brought it in for diagnostic. We researched online and found the class action suit for "accelerator pedal sensor" being faulty. We believe this is what's going on. It's currently at the garage getting diagnosed. This is a known, dangerous issue that GM should take responsibility for!

When parking car we place the shifter in park, and psh the button to turn off car it states to “Put shifter in Park” after wiggling the shifter that is clearly in park the car will shut off. Also the breaks will pulsate at slower speeds like the ABS is kicking in, but is not the case. Along with the pulsating there are loud thumping noises. Car today when driving did same thing the said “reducing engine power” almost made it home then completely died on me in middle of road. Was told it could be because of bad vacuum pump, brake booster sensor, and brake booster by my mechanic. He said in newer cars this would prevent the car from starting.

When the vehicle is in park and you try to turn it off with the start/stop button an on dash error code of ‘Shift to Park’ appears even though the vehicle is clearly in park. You are not able to turn the vehicle off. I am very concerned this could cause major safety issues! When I searched for it, it appears a lot of GM owners are having the same issue. Please issue a recall!

After coming to a complete stop and moving the shifter into Park, a message on screen in my car displays SHIFT TO PARK, while the icon in the bottom right of the screen clearly displays the car is already in park. This has been happening consistently over the last few days. I have learned that if I get a bit more aggressive (jam the shifter into Park) it tends to work although I'm not sure how long that will last without causing additional issues. If I can't get my car into Park, it may roll and cause injury/damage/death. I have not yet taken it in for inspection as it just began this week.

Driving down highway slowed down brake assist kicked in for no reason I was stuck in traffic not moving but maybe 2 mph brakes locked up got super hard codes read brake booster and vacuum pump. Screen went black “parking assist off” came on dashboard earlier that morning but nothing seemed to be wrong with the car. Thank God I wasn’t going faster I could have died!

Driving vehicle like normal and then the check engine light comes on with the stabilitrak light, and get message "reduced engine power". Car goes down to less than 50 miles per hour and is struggling to go must faster while I am on the freeway. The RPMs keep going higher and higher even though the car is not going very fast. Get home and let it rest. Keep having same issue on and off past two weeks. Sometimes it comes on and goes off, has been on past three days acting the same way. Check engine light says Pedal Sensor issue. Known recall for it listed with letter sent out in 2019, but of course this was only if you were having the issue at the time (which I didn't) and it is only covering for cars under 150K miles. My car has 192K miles, so they will no longer cover it, even though it is a known issue has been for some time now! It is very expensive and unfortunate that they will not cover this issue regardless of miles, knowing that this can happen to the 2017 Chevy Malibu's at any time. Still driving it the way it is. Did try to clean out the Throttle body and see if that helped, but issue still is there. Will try to replace sensor at some point and see what happens.

While driving on 12/28/2022, my brakes suddenly became very difficult to apply pressure- almost causing a cramp in my calf because I had to press down so hard. Took the car to a repair shop, only for them to tell me my brake pads are fine. It turns out the problem is with the vacuum pump associated with that part of the car. Looked online to see if this was a common problem and as it turns out, there's a class action lawsuit in litigation about this very issue.

Engine shuts off while driving and sometimes will not restart. This is not the regular start/stop functionality. My car shuts of when it should not and creates a crash hazard.

ENGINE LIGHT CAME ON ALONG WITH DECREASED ENGINE POWER LIGHT. FELT THE TRANSMISSION DOWNSHIFTING. SPEED WENT FROM 50 DOWN TO 20 WHILE ON AN EXPRESSWAY AND I HAD TO PULL OFF THE ROAD AND SHUT IT DOWN. WAITED AWHILE, TURNED IT BACK ON AND IT CONTINUED SEVERAL TIMES TO DOWNSHIFT. TOOK IT TO THE DEALER, HAD TO WAIT A FEW WEEKS FOR THE PART AND THE ACCELERATOR PEDAL SENSOR NEEDED TO BE REPLACED. THANK GOD I WAS NOT IN THE PASSING LANE OR THERE WOULD 'VE BEEN A VERY BAD ACCIDENT.

NHTSA ODI 11495573

During driving on the highway, the car went into reduced power mode and speed was limited to 30 MPH. This was during driving on highways with 55 MPH or 65 MPH speed limits and could have resulted in an accident. My daughter was driving the car on all 3 occasions which makes this problem even more upsetting. The same part has been replaced 3 times (refer to receipts) relating to the accelerator pedal 3.451 N. This is a MAJOR DEFECT that is reoccurring. NHTSA needs to take action on this safety defect with General Motors for a corrective repair. I see this has been reported before on this website by others. You immediately action on this matter is appreciated.

About 2 years ago I began having issues with my 2017 Chevy Malibu right before I hit my 100k mile extended warranty. The error message "Engine Power Reduced" appeared on the dash while driving on the interstate and my car began rapidly decelerating on its own. I had no where to get off the interstate and pulled over on the side. I shut my car off for a couple minutes, restarted and went on my way for about 30 seconds when it happened again. This continued making my normal 45 minute commute home far longer. I took it into the dealership right away and the replaced the accelerator sensor. Problem solved for just over a year when it happened again in February 2022. The car was no longer in warranty so we took it to our local mechanic who said it was the same issue. We replaced the sensor for a second time. Now, November 2022 and it is happening AGAIN. This is not a cheap repair and is a major safety concern when driving at high speeds and the car decides to rapidly decelerate, not allowing me to drive more that 20mph. I live in Wisconsin where roads are slick in the winter. Losing control of the cars speed is a serious safety concern for myself, anyone in the car with me and those driving behind me. I understand this is a well known issue with the models between 2016-2018 but GM has failed to recall these vehicles. Why? Why is nothing being done about this? 3 times in 2 years is ridiculous and there are thousands of cars that have reported this exact issue. Please help.
