The Power Brake Vacuum Assist Failure nearly caused a wreck. The part failed while we were driving on [XXX] going 65 miles per hour on a busy highway. As the breaks gave out the engine light said “Reduced Power”. Moments later, the breaks stopped working and the engine stopped running. We were able to coast off the highway and into an HEB parking lot and have the vehicle towed. The mechanic took the part off and found that it was in pieces causing further examination of the engine to look for the missing metal. Pictures are available to see the damage. Even after completing the repairs the vehicle is showing reduced power. We are still trying to get it fixed but understand that the Chevrolet company is aware of the issue but never issued a recall.

2017 Chevrolet Malibu acceleration complaints
Page 2 of 6: complaints 11 to 40 of 135, newest first, as owners wrote them.
Ice and sludge accumulated and froze causing the CAC system to fail resulting in engine issues, performance loss this was caused from GM poor design of a shield that they are aware of. GM knows that this can happen and have now designed a new shield to prevent this from happening but it is at the owner’s expense to fix. If GM knows that this will happen they should fix the issue I am now out of pocket 3,000.00 shame on them
My car displayed "reduced engine power" and slowed down on the highway while I was doing 65mph. My car would not accelerate past 20mph. There were no issues with my vehicle, and this happened out of nowhere. It caused a lot of other drivers to have to swerve around me, and drastically reduce their speeds as well in order to avoid collision. This was highly unsafe and now I can not safely drive my own car.
Check engine light came on. Display stated that the engine will run at reduced power which meant we had to Limp home at 15 MPH which put us in a dangerous situation. I read the code and it was P2122. Throttle/Pedal Position Sensor/Switch “D” Circuit Low Input. This indicates that there is a problem with the accelerator pedal. I replaced the pedal myself at a cost of $114.00. I eventually found a technical service bulletin that admitted that there is a problem with the accelerator pedal on 2016 to 2018 GM vehicles and there was a program that was replacing the pedal until 2020. I called GM customer service and they said there was nothing they would do about it since the program expired in 2020.
Error message reads "Engine Power Reduced". I was on the highway and suddenly the engine gives out and only lets me go to a max capacity of 20 mph. I able to safely remove myself to the side of the freeway. A week later without moving my vehicle I checked to see the status of my car and the error message removed itself. It's been over a year now with my engine power coming and going, just as fast as it comes, it goes-- making driving very unreliable and unsafe to step onto the road. Apparently I'm not the only one with this concern according to [XXX] , a class action lawsuit has been charged against Chevrolet in The Rothschild v. General Motors LLC Chevy Malibu Class Action Lawsuit is filed in the US District Court for the Eastern District of New York under case number [XXX].

When l park my car it keeps saying it’s not parked
I was driving my car at a normal rate of speed when all of a sudden it slowed down to a crawl and almost caused an accident, reduced engine power and engine came one after getting the codes they were 2122 and 2097
The day I bought the vehicle in 2019 the engine light came on, I took the car back to the dealership and was told they couldn’t do anything. I took it to them and the shop here in town and I was told by both shops on multiple occasions they could not fix any of the issues. They treated me like I’m just a paycheck for them. My car for 3+ years now shuts completely off when I slow down or stop, including on highways. “Engine speed reduced” message comes up every time I drive. Now I am being told my brakes are going to go out and nobody can help me. I have to step on my gas after I start the car or it just sputters.
Reduce Power Engine appears on the dash board. The car starts slowing down, I can’t speed up, I Have to park on the side of the heavy traffic in the Highway. I have to wait around 5 minutes and then drive. I still have the engine symbol on. This happens regularly like 2 to 3 times a week.
My car has reduce engine speed. I’m driving on the highway and out of nowhere the car shots down and a symbol appears on my dashboard that says Reduce Engine Speed. Literally the car slows down to a minimal speed until I can’t drive anymore. I have to stop and turn off the car for 5 minutes until I can turn it on and drive to my destination in a reduce speed.
2017 Chevy Malibu has P2138 showing up.. I was on the highway loss half the power to my car, almost causing a major accident, went from 65 mph to 30mph in seconds.. This is a safety issue & needs to be address ASAP!! I have my vehicle at the dealership, the service teams seems to have no clue that there is an issue with the mailbu's !! The P2138 is defined as “Throttle/Pedal Position Sensor/Switch “D”/”E” Voltage Correlation.” It is triggered when the vehicle's Engine Control Module (ECM) detects that the signals from the two throttle position sensors or the two accelerator pedal position sensors don't correlate.
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.
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.
My check engine light came on and I had reduced power and could not speed up. I have seen other with same problem 2017 chevy Malibu. This needs investigated big time before someone gets hurt. Should be a recall on this.
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. the federal safety agency 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.
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.
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.
Upon leaving work and gaining speed to 40mph I received a dash notification specifying engine power reduced and my mileage went down abruptly to 20mph. My check engine light came on and the power steering light appeared on my dash with the engine power reduced notification. I was not able to accelerate past 20 mphs.
Small trip to Georgia granddaughter’s birthday. Vehicle just went in limp mode. Lost power brakes. My brothers code reader showed P0 014, P0 017, P1101, P0016. I’m pulling up and showing on NHTSH for open recalls and one complaint. I’m trying to make a complaint. The car we turn off. Wouldn’t crank back. Sometime when you wiggle the wire by the throttle it would crank. No power breaking. No engine pole to go up hills. No speed. On Google and YouTube I have found recalls of powertrain automatic transmission six recalls on the website. CHEVY MALIBU vacuum pump recalls. I’m having a vacuum leak you can hear it when the car does turn off the engine fan runs for ever. I’m showing problems with CHEVY MALIBU vacuum Val cover gasket recalls. Problems with CHEVY MALIBU brake vacuum pump recalls. Problems with CHEVY MALIBU 2013 through 2022 booster vacuum pump recall the defect. Problem showing GM 1.5 L POO14 Dash P0017 exhaust camshaft timing. Somethings gone major wrong and I’m showing recalls and I am looking for GM to fix this car I have a A lot of money in it and still owe a lot of money on it.!
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.
Shifting delays that cause loss of power for the past 2 years. I would have reported sooner but did not know how until now.
The contact owns a 2017 Chevrolet Malibu. The contact stated that while driving and attempting to accelerate, the vehicle jerked and decelerated from 65 MPH to approximately 20 MPH; the vehicle then independently accelerated to 40 MPH. While at a stop sign, the vehicle stalled. The engine power reduced message was displayed. Additionally, water had entered the trunk of the vehicle and the contact was concerned about mold. The vehicle was taken to the local dealer where it was diagnosed and determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified but no additional assistance was provided. The failure mileage was approximately 180,000.
For over a year now my car has a weird hesitation when I press the gas and fully have the pedal down it just crawls no more than 8mph then all of sudden it will jump into speed and take off. The shop has had my vehicle for over 3 months and couldnt figure it out just told me to put premium gas in and that still hasnt solved the problem. This car has been NOTHING but problems. Havent even had it three years and its been in the shop for almost 6 months in total
Complete loss of engine power while going 65mph on highway. Warning light of low power first followed by check engine light then power reduced to 5mph. I turn the car off then restarted after 15 minutes, the morning light was off but the check engine light remained on. I then went to AutoZone to have a diagnostic test done which resulted In error code P2138. P2138 is for throttle/pedal position. My vehicle should still be under warranty however due to short staffing I am unable to make an appointment to have it looked at for at least six weeks
Transmission and engine alert
I was driving at 60 mph the check engine light came on the engine power reduced message appeared on the screen my speed dropped to 20 mph and loss acceleration I abs to pull over to the side of the road
The car will be driving fine and all of a sudden I engine power reduced pop up in the car. It's slows down significantly and not safe for a highway if this happens you will wreck or something worse. It is happening often now and I don't know why. Engine power reduced the the t/c light comes one and thr check engine light.i pull over and turn the car off. The check engine light stays on then the car drives like it had a crazy episode and not ready to drive. It's scary and unsafe and it needs to be looked into
