2017 Chevrolet Malibu

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.

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.

I have a 2017 Malibu and have gotten a message on my MFD (Multi-Function Display) screen on the dash that said Steering Assist Reduce, drive with care. It happens while driving city streets and at a complete stop. Now the doors are unlocking when the message pops up at stops. Also the care is losing power at the stops now and coming back on. It does not allow me to accelerate. This is very dangerous. I took my car into the dealership a couple months ago for the same error message but they blew it off saying I needed some type of fluid (if I remember correctly). Now, I have the same issue amplified. It wrecks lemon! I filed another complaint months ago, but I’m filing again due to scheduling yet another service appointment at the Chevrolet dealership. (Hence why I put todays date of the incident).

The accelerator pedal position sensor failed causing reduced engine power mode. This happened on the highway with the speed limit of 55 which reduced my speed to 20 mph while around other vehicles. This put the safety of myself and my two children at risk because cars behind me didn’t expect a sudden change of speed along with myself. Having no warning is insanely scary. This problem is apparently not a recall on my car but yet I’ve found the gm recall online for Chevy Malibus years 2016-2018. This hasn’t caused an incident yet but I have seen MAJOR complaints and how this is a reoccurring problem which isn’t surprising to me because I had a 2012 Chevy Equinox before this with the SAME issue. Having this happen twice is ridiculous in my opinion. This happened two weeks after I bought the used car from a dealership it only had 59,000 something miles but I am disappointed as to how this is costing me already. This makes me never want Chevy or GM again.
