2017 CHEVROLET MALIBU Vehicle Speed Control Problems

The Reduce Power to Engine keeps happening. It shuts my car down and lights up the traction control light, check engine light and its a serious hazard because I travel highway to and from work and its very dangerous when you loose power to your vehicle at high rates of speed. Also my emissions is bad due to a supposed fixed recall for the catalytic converter.

While driving at highway speeds, my vehicle suddenly experienced a loss of engine power and reduced acceleration. The traction control light and engine light illuminated, and a “Reduced Engine Power” message appeared. The vehicle would not respond to the accelerator, creating a serious safety hazard. This occurred shortly after authorized dealer service involving the PCV system and related components. The vehicle did not have this issue prior to dealer service. I returned the vehicle to the dealer, and they stated they could not replicate the issue. The sudden loss of power could have resulted in a serious accident. I believe this may be related to improper dealer service, disturbed electrical connectors, or throttle body/engine management components. I am reporting this as a safety concern. I also would like to mention this safety issue has occurred now multiple times with my car on multiple separate occasions with the last prior occurrence...

The car smells strongly of gas. And has a problem accelerating. Check engine light came on and I got a code p1101 which is a code for the MAF SENSOR. This is not the first time that this has happened. It happened less than a year ago maybe 9-10 months ago. I don’t drive the car in fear of it catching a fire. The car has stalled before in the middle of a turn. I had to turn the car off and turn it back on. I called onstar who have no idea what was wrong with it.

The transmission stalls to get up and go after it has been driven for a short while causing it to slow down traffic and causing a slight risk trying to pull over to the side to allow drivers behind pass by. Once the driver stops at more than 5 stops is when the vehicle begins to hesitate to work properly.

I was driving my car on the highway doing 65 mph when all of a sudden my car started rapidly jerking losing the power to accelerate and entering “limp mode“ there was multiple cars behind me when my car lost the power to accelerate. I was in the far left lane and couldn’t even go higher than 7 miles an hour and had to cross across three lanes at 7 mph on a 65mph highway to pull over. I had my children in the car and almost caused a huge accident dude to this issue. The issue in hand is the vacuum pump. It completely shattered in my engine, causing severe engine damage. And it caused my brake pedal to become hard as a rock. I couldn’t break without using my emergency break. I had no brake power at all. My car had to be towed.

I was driving in my neighborhood I tried to park at my house and my car wouldn’t stop I had to step down on my break hard for it to finally stop my vacuum pump broke into pieces and made my timing chain break

Engine power abruptly stopped while driving causing drivers behind me to almost rear end me. Dashboard displays ‘Engine Power is Reduced.’ It has happened since I purchased the vehicle in 2017 but had not done this in a few years. I’m on top of maintenance and did mention this issue to the dealer but no one reached out or offered a solution.

When driving down a major highway going 70MPH, my 2017 Chevy Malibu speeds decreased, the brakes locked up, and the vehicle would not accelerate. Eventually the car came to a complete stop and an “engine power reduced” notification came up on the dash. I was able to pull off to the side of the road but I was traveling at a high rate of speed on a busy road, I almost got hit multiple times by people behind me who also had to swerve out of the way to keep from getting hit. After turning the car off and on again it seemed to run fine for a few months until the issue happened again going down a busy highway (65mph) again putting myself, my kids and others on the road behind me at risk. Now the car won’t move more than 5 feet before shutting off with “ engine...

I was in the freeway and out of nowhere an alert message popped up on the dashboard saying Engine power reduced. This made my car go from 65mph to 30 mph is the freeway luckily I was able to exit and go to the nearest gas station and was able to keep myself safe as others on the road but it could've easily gone very badly. The car won't go over 30 mph. The car is available for inspection upon request, I seen a PDF in the nhtsa website of a special coverage adjustment for loss of continuity within acceleration pedal position circuit. I will attach it to this message.

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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]. INFORMATION REDACTED PURSUANT...

When l park my car it keeps saying it’s not parked

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.

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

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.

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.

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...

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...

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. 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...

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...

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...

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...

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....

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

The contact owns a 2017 Chevrolet Malibu. The contact stated that while driving approximately 60 MPH, the “Engine Power Reduced” warning light illuminated and the vehicle inadvertently decelerated. The contact was able to pull over safely. The contact called the local dealer and was provided an estimate for the diagnostic fee; however, the vehicle was not diagnosed nor repaired. The manufacturer was not contacted or informed of the failure. The failure mileage was approximately 64,000.

The vehicle constantly reduces speed when there are no issues with weather or any other issues on the road. This issues can potentially be fatal. I have had it checked and the diagnostic machine says it’s sensor issue that was reported for recall but my car was not part of the said recall. The car completely shuts off and will turn on by itself after 10 minutes. Uncertain what to do

While merging into traffic my 2017 Malibu's power reduced (reduced power indicator appeared) which resulted in my inability to control the speed/acceleration. I've had two additional incidents. Very unsafe deficiency.

On January 2022, Wednesday the 19th. My husband, myself and our two daughters 12 & 4 are on the Northbound freeway 99 in the far-right lane and the car pops up with the warning “Engine Power Reduce” and then proceeded to decline in speed from 70 MPH to 15 Mph almost instantly almost causing an accident. WE all were so shaken up! Had we been in front of a big rig we would have been crush from the backseat as fast as the speed declined. WE just bought this vehicle 5 months ago no more than 10K miles on it. The dealership says its not there problem to contact GM. Nobody will help this is a death trap vehicle. There are already multiple class action lawsuits about this issue and the vehicle. We are simply being told to buy a newer vehicle rather then someone taking ownership of this issue....

Low Engine Power message appears , my driving speed dismished I was on the highway driving and the light appeared, I also needed some fuel, but I did eventually stop added gas engine light disappeared but it eventually reappeared again and has remained with full tank of gas

Driving on highway at about 65 mph on family trip to Delaware. . Car suddenly gave reduced acceleration error and speed started declining while in traffic. No warning.checked chevron app on phone and it did not see anything wrong. There was NO check engine or anything. Got to a dealer and they said it was probably a sensor for gas pedal. 5 days later driving home to Georgia from trip on highway around same rate of speed. No warning . The check engine light and reduced engine power warning message came on. This time the Chevrolet app notified me of trouble and said I needed the car seen within a day. .Got to a dealer and now they say they think it may be the cam shaft based on the code but they cannot replicate issue. I took a photo of the alert from the second incident . Car has...

Throttle Position Sensor is falfuctioning. Class action law suit against this already. Chevy Malibu Class Action Lawsuit is Hutchinson v. General Motors LLC, Case No. 8:19-­cv­-01551, in the U.S. District Court for the District of Maryland. Vehicle decelerates at highway speeds down to 20 mph and engine power reduce comes across the screen. Has almost caused me to be in three accidents. Need to recall all malibus and have this part replaced before someone is killed.

I was driving on the interstate and the dashboard said Engine loss of power. It was very dangerous because it reduced my speed drastically in the middle of traffic! My whole family was in the car and this is the 3rd time this has happened to me since purchasing the car. And now my check engine light is on. I don’t understand why this happens, but defective parts that create this problem put our lives in danger! Why is there not a recall on this? This is very important and should be fixed immediately! I almost wasn’t here to write this so please show me and other owners of these cars in these model years how to not die in your vehicles please?!

THIS IS MY SECOND COMPLAINT AND POSSIBLY THE LAST, IN MY FIRST COMPLAINT I REPORTED THE PROBLEM WITH THE CAR AFTER SHOWING A STABILITY TRACK WARNING LIGHT THEN SLOWING TO A 20 MPH VELOCITY IN A SNOW STORM , THEN MY ADVENTURE WITH THE VACUUM PUMP SHATTERING , THUS NO VACUUM, NO BRAKES, ON THE HIGHWAY GOING 70 MPH. AFTER THAT SCARE , IT HAD A CRANK NO START PROBLEM. THAT'S WHERE I ENDED MY FIRST COMPLAINT . PART 2, I COLLECTED MY STIMULUS MONEY AND HAD MY 2017 CHEVY MALIBU LS TOWED TO A CHEVY DEALERSHIP. AFTER THE SERVICE MANAGER ASKED ME FOR THE SPARE FOB, I ASKED HIM COULD THAT BE THE PROBLEM THE BATTERIES WENT LOW AND THE FOB KEYS HAD TO BE RE-PROGRAMED. HE STATED PROBABLY, I WENT HOME HOPING IT WOULD BE SOMETHING MINOR. 3 WEEKS LATER I GET A CALL FROM THE SERVICE MANAGER...

SPEED REDUCED ON FREEWAY TO 20MPH, SPEED REDUCED WARNING WITH CHECK ENGINE LIGHT ON.

AS WE WERE GOING 75MPH DOWN THE HIGHWAY THE VEHICLE STARTED DEACCELERATING WITH THE CHECK ENGINE LIGHT WITH THE FOLLOWING MESSAGE APPEARING ON THE SCREEN 'ENGINE POWER REDUCED' WE HAD TO QUICKLY PULL OVER TO THE SIDE OF THE ROAD TO AVOID HAVING A WRECK. AFTER SHUTTING THE CAR OFF FOR A LITTLE BIT THE MESSAGE DISAPPEARED. AFTER LOOKING INTO THIS THERE A MULTIPLE PEOPLE WITH THE SAME CAR AND SAME ISSUES, BUT NO RECALL OR INVESTIGATION HAS BEEN STARTED.
