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!

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.

The check engine light came on and the stabilitrak came on. I went to nearest car mechanic and the mechanic told me it was safe that-??s normal and it was safe so I proceeded to goto work the next day. The next day I-??m on my way to work and 30 minutes on the highway my check engine light come on this time saying engine power reduced I went from driving 60mph to 20mph with four wheelers speeding pass me. Being far away from home I pulled over side of the highway to not panic. I turned on my hazard lights and proceeded driving and made my way home because I didn-??t want to be stranded.

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.

- West Sacramento, CA, USA

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.

I have taking my car to Chevy 8/2021 twice and now 9/28/22 for what I believe to be throttle body control and accelerator pedal issue. The engine reduce light and check engine lite continues to come on causing my car to lose speed while driving. Chevy keeps telling me its a oil pressure issue now their saying it may be a oil gasket. At this point I feel like there is a lot of complaints of the same issue. I'm hoping someone can look into this further as it's costly and seems to be a chevy issue nation wide. I see there has even been a lawsuit : Jun 9, 2022 -?" A class action lawsuit against General Motors alleges the company hid a defect in its Chevy Malibu that can cause a sudden loss of power. https://topclassactions.com/lawsuit-settlements/consumer-products/auto-news/chevy-malibu-class-action-alleges-power-defect-cover-up/ I feel like this is very dangerous and I don't want to get hurt or hurt anyone in the process.

While driving, car speed decreases to 20 MPH. I continue to push the pedal and then suddenly revs up to pedal speed. The vehicle jerks while this is happening. There has been a loud clinking sound under the pedal area. No warning lamps. This happens intermittently and dealership will not do any repairs without a code or replicating the issue. This is a huge safety concern and I can no longer drive this vehicle safely. What can I do to get this repaired?

Vacuum pump has stopped working properly causing it very difficult to brake. Autostop feature has stopped working properly due to this problem. This is the second time I have had issues with the vacuum pump.

My car has been in and out of the dealership since I purchased it back in 2017. The vehicle shuts off while I am driving it. The first time this happened I was on the highway with my 5 year old son. I completely lost power and had no control being my steering wheel locked. Since then I have repeatedly had the same issue. Each time calling the dealership and each time they find either nothing wrong with it. Or say they fixed the issue which I was charged for. For the same issue that was fixed to happen again. This happened yet again today as I was making a left hand turn onto a 4 lane highway. It happens atleast once a day. I lost all power to my car. Steering wheel locked and car refused to start. There is something going on with this car and many others. The dealership I purchased it from agreed and offered to get me into a new Malibu being it-??s a safety issue but I want nothing to do with another Chevy after my research. Too many issues with this car. THIS car has already been fixed for the recall involved AND this is still happening. And the car also won-??t go into park. It says shift to park which drains the battery because the car never really shuts off. Before the recall I payed for repairs out of pocket for what the dealership -??thought-?? it was which it was not. Clearly because the same thing keeps happening. Nothing different. It-??s all the same. This car is a lemon. God forbid my car stops in the middle of a highway and won-??t start. I won-??t say the rest but if there are any injuries or the worst I have documented everything through my dealership. My family and I will sue.

Since purchasing this vehicle I have had to take to repair shop several times due to the automatic shut off when at a stop light but car cuts out completely and sometimes will not start back up. I have had to be towed to the shop I have had to replace the battery once already because of this and looks like will have to replace battery again because it has started doing the same thing again. I have only had this car a year and am ready to give it back to the dealership.

Vehicle check engine light came on. Then a warning saying reduced engine power came on. I then lost most of my accelerator and slowed me down from 65 mph to about 30 right in the middle of the highway. As I was pulling off to the emergency shoulder my brakes became very stiff and started pulsating rapidly. I could hardly press the pedal enough to make the vehicle come to a stop safely.

Car looses power randomly -??engine power reduced-?? comes up on the dash screen have to pull over sh*t car off and then turn back on to reset.

- Indianola, IA, USA

I have had this issue 3 times since purchasing new in 2017. Power completly turns off while driving. No warning no nothing just turns off. I had my pistons and all that replaced back in 2019, I have also had the battery replaced 3 times since getting this vehicle as that Is what gm recommended. Nothing is helping. It now tells me to service stabilitrack. Tells me my power steering is out. It-??s not safe to drive. It sits in my driveway and I am waiting money monthly paying on it. It also gives me a shift to park error while it-??s already in park. This is a dangerous car and do not recommend it. Chevy was so gracious to tell me they-??ll give me half of what my vehicle loan is. So nice. Ya right what a joke. I have pulled up these issues from other buyers of this car and they say there-??s ni recall so nothing they can do. I-??m not sure what other steps to take I just need out of this car. And so does everyone else. It-??s dangerous and the fact that nothing has been done by the federal government about this is worriesome.
