2017 CHEVROLET MALIBU Complaints

“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

The contact owns a 2017 Chevrolet Malibu. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to an independent mechanic to be diagnosed. The mechanic retrieved fault code: P0138 (engine control module (ECM). The vehicle had unknown repairs completed; however, the failure recurred. The contact made the independent mechanic aware of the failure; however, the vehicle was not taken back to be diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was unknown.

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!

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!

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 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.
