2017 Chevrolet Malibu

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.

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.

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.
