Problems with 2017 Chevrolet Malibu POWER TRAIN

On average, the 2017 Chevrolet Malibu starts to “feel” problems with the POWER TRAIN and its various aspects after 52 280 miles.

Recently reported POWER TRAIN problems on 2017 Chevrolet Malibu

When you shift to park a light comes on that says it isn't in park . so the lights will not shut off . you have to repeatedly shif from drive to park until it turns off . there are thousands of complaints online . it cost me 286.00 to fix it i was 1000 miles over my warranty.

For 3 months my 2017 chevy malibu has had the check engine light come on, and vehicle completely loose acceleration. at slow and high speeds with my 2 year old in the car. when the code is read it states it's the ecm p2138. this last time almost caused my vehicle to wreck with my family in the car. chevy has yet to handle the issue and like most cars it's not covered on warranty so because chevy has put out a faulty product we are being punished with high mechanical costs. this is not the first issue, i have have my chevy almost 3 years and have had it in for sensor issues reading the key fob and my car stranding me hours from home and not starting, and again for sensory issues putting the vehicle into park. when confronting chevy they state the issue with high cost to fix.

While driving on freeway going 70 mph, my traction control, check engine light, and a warning flash across my dashboard saying engine speed reduced. my car went from going 70 mph to 40 mph and wouldn't go any higher. i immediately got off the freeway took pictures of the lights. luckily i have a anti left device that reads off codes for my check engine like code p2138 is what came up. this is extremely dangerous, i had my [xxx] child in the car with me and was almost rear ended due to loss of power from such a high speed. *dl parts of this document have been redacted to protect personally identifiable information pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

When parking the vehicle and turning off the ignition the dash lights up "shift to park" had to work and work with it to get the car into park to where it could be exited from. took to dealer and with extended warranty had to pay $200 deductible for a fix that i have heard many are having with the 2016 and 2017 year model gm products.

When driving the car, it will suddenly decelerate. check engine light appears with the following message "engine power is reduced". this has happened many times in the last 2 months and has not been fixed by gm.

The electrical blinks out . engine reduced speed is a problem and is very damgerous i was almost hit on the freeway. this car is a dud and most models like it have the same problem.

Vehicle abruptly slowed in heavy traffic for no apparent reason. vehicle was diagnosed as having a faulty accelerator pedal. part was replaced at owners expense 14 months into the life of the car. 8 months later the vehicle started to do the same thing for the next 5 months, sometimes 3 to 4 times in one day or not al all for several weeks. car was again presented to dealer for diagnostic and it showed that the same fault occurred. this is a severe safety issue that needs to be addressed by general motors. fault codes p2138 for accelerator pedal, c0242 and u0401 for traction control system. neither of these faults were addressed by the dealer during the repair.

Car will indicate 'engine power reduced' and will abruptly reduce speed. this is a major safety concern not only to myself but other drivers on the road as well. why is there no recall for this problem? i see it is a major problem with these models of chevy malibu. happens everyday, most of the time more than once. my commute to work is about 25min and it did it 3 times today.

Going into park the car says you need to shift to park. car will not shut off.

Tl* the contact owns a 2017 chevrolet malibu. the contact stated that the vehicle would shut off while driving various speeds and the engine power reduced warning indicator illuminated simultaneously. the contact had the vehicle towed to an independent mechanic who informed her the failure was due to the camshaft vacuum pump. the contact called van chevrolet (100 nw vivion rd, kansas city, mo 64118, (816) 527-8564), but no assistance was offered. the manufacturer was not notified of the failure. the vehicle was not repaired. the failure mileage was approximately 65,000.

I was traveling in my vehicle on the highway going at least 65 to 75 mph and all of a sudden my vehicle beats two or three times and across the screen came the words 'reduce engine speed'. at that moment i was traveling in the middle lane and i had to safely get over to the far right median in the middle of traffic safely turn off and wait at least 10 minutes to start it back up. when i started my vehicle back up again i still received the same message. i then waited even longer and everything was ok but eventually the same issue continued to happen several times. i took my vehicle to get coded and the codes that were given to me were 2122, 2123, 2101. it's unsafe for this to happen especially i have a child this is no safe for me.

Tl* the contact owns a 2017 chevrolet malibu. when attempting to park the vehicle, the instrument panel stated that the gear shift must be placed in the park position, even though the gear was already in the park position. the contact stated that the gear shift had to be jiggled or changed into another gear various times before the instrument panel displayed that the shift was in park. the vehicle was taken to koons clarksville chevrolet buick gmc (12421 auto dr, clarksville, md 21029, 410-988-9522) where it was diagnosed that the shifter assembly was damaged. the manufacturer was contacted and provided case number: 9-541350439. the failure mileage was 38,680. *tr gm stated the malfunction would not be covered even though it is a safety issue and power train issue and should be under warranty.*jb

Shift to park light would display on the control panel and the car would not cut off completely.. this issue began intermittently and finally became constant. diagnostics found internal fault in the shift control. shift control was removed and replaced at a cost of $394.77 by woodall chevrolet in danville, virginia

Recently when turning the car off a warning light appears state ' shift to park' even though the gears are in the parked position.

Indicator light repeatedly comes and says, please shift vehicle into park. when the vehicle is already in park. i will have been pulled in my driveway already in park mode, i will have to keep starting and stopping the vehicle to get the vehicle to recognize it is already shifted gears into the park position. this has happened more than 6 times since i have had this vehicle in the last 2 years

On saturday, june 29th, 2019 approximately at 12:30 pm my family's 2017 chevrolet malibu was in motion in a major interstate (i-75) and the traffic started slowing down, i pressed the brake pedal to slow down and the pedal became very hard to brake and having to swerve to the side of the right side of the road to avoid a collision with the vehicle in front of me. the vehicle's message board read "engine power reduced". i also received an email message from on-star stating that an issue with the engine and transmission system was detected. the vehicle was taken to victory lane chevrolet in fort myers, florida, and the service technician told us that the issue had nothing to do with the engine or transmission as the vehicle message stated, but a problem with the braking system's vacuum. this could have been a really bad accident and hope that this information can help avoid any problems to anybody. we are still worry about driving this vehicle, since we are becoming aware that this is an issue that seems to be repeating itself to many other owners of the same vehicle and model as our malibu in the united states and canada.

Tl* the contact owns a 2017 chevrolet malibu. while driving 30 mph, the accelerator pedal was applied, but the vehicle failed to respond. there were no warning indicators illuminated. the vehicle was towed to an independent mechanic who stated that an unknown sensor needed to be replaced. the vehicle was not diagnosed or repaired. the dealer and manufacturer were not contacted. the failure mileage was 79,000.

I bought this car august 2017. when i put my car into park it states that it need to "shift to park" even though it is park. it happened once and then after that it was like almost every time i park my car. when i turn the car off is when the alert happens, then you have to restart the car and take out of gear and try again. it happens up to 4 times before it finally works. it is like you have to jam it into park to make it realize it is in park. taking into the dealer to have it looked at on 06/27/19. hopefully it will get fixed. to new of a car to have issues this early. not a happy camper at all!!!!

Tl* the contact owns a 2017 chevrolet malibu. the contact stated that the accelerator pedal malfunctioned and was repaired twice. in addition, the vehicle stalled and the transmission was repaired three times. biggers chevrolet (1385 e chicago st, elgin, il 60120, (847) 742-9000) made the repairs under warranty. the accelerator pedal failure recurred and the vehicle was currently back at the dealer. the manufacturer was contacted and provided a case number [xxx]. the contact was informed that a senior adviser from the manufacturer would call back within two days. the failure mileage was 50,522.*bf *tr *tr *as consumer stated the engine light has been fixed multiple times and transmission. the accelerator has been replaced 4 times as well. door panels came off, carpet came up, trim by rear shaft came up. the car was surrendered to jerry biggers. history listing reference #xxxxxxxxx 'parts of this document have been redacted to protect personally identifiable information pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).'*jb

Car will advise to "shift to park" when vehicle is already in park. vehicle will not shut off. shifter assembly issues and needs to be replaced. thousands of customers have been affected according to chevrolet forums and youtube videos

Shift to park warning appears on dashboard after vehicle has been placed in park and power button is pushed. the shift to park message prevents the vehicle from shutting off. vehicle only had 37,324 miles the first time it occurred. i pushed shifter forward and vehicle shut off. the issue happened once more on the same day then stopped for about two weeks before it did it again and took more than just pushing on shifter to allow vehicle to shut off. i took the vehicle to a chevy dealer which was out of the bumper to bumper warranty to be told this is a problem they have seen before. i paid for the work to be completed but also conducted research and found on a chevy forum this is a known issue. if that is the case the safety feature of not allowing you to shut off your vehicle if not in park is drastically compromised when these controls become faulty. since chevy is aware of the issue with their shifter control switches they should be held accountable to replace them with a shifter that is not known to have issues as this could become a safety issue for individuals who do not have the $700 to fix the problem. i have attached a copy of a service bulletin pulled from this website and snippet of service request and confirmation of issue

Issue with chevrolet malibu 2017 with 60k miles. i am right around the time where my warranty would be over, and i have having issues with a car that i drive on the highway for 90-95% of the vehicles life. my car is cutting the power to the engine at random times. this has happened on the highway around the same percentage of times that i've driven the car in total. i've had to move over to the breakdown lane, and shut the car down. it would power back up, and typically i would be ok, but this is highly dangerous. the engine light would stay on until the car sits for a while, and then go away. then i would drive seemingly fine, then boom, on the highway going 65-70, and the engine is reducing power, and i'm scrambling to get over. i am taking the car to the dealership, which has been the only mechanic to look at my vehicle. i did receive new tires from another place, but all other scheduled maintenance has been with my dealership. i am afraid i will have to pay for this and this is a joke because this seems to be a known issue. there are many threads explaining what could be the issue and i would like a follow up on how my experience with my dealership went. when i called my dealership's service location, they seemed to be extremely familiar with the issue i was having. it was strange that i couldn't get a straight answer either way, and i don't feel i should pay for something that is clearly a manufacturers defect of some kind. not only that, i've been put in dangerous situations while on the highway in bad weather trying to manage, as quickly and safely as i can, a way to get over to the breakdown lane(shoulder). when i press my accelerator and nothing happens when everyone around me is going at a very high rate is speed is an issue needless to say. there should be no reason a recall isn't announced for this issue and chevrolet held responsible.

Back in the 1st week of january 2019 i experienced the first major issue. while i was driving to work on the highway traveling at 65 mph the cars check engine light went on as well as the traction control. the vehicle immediately sent a message on my dashboard that said "reduce engine power" and the car jerked and the speed drastically dropped from 65mph to about 20mph. i was unable to accelerate and was luckily able to drive to an emergency lane while cars and semi trucks were behind me and almost hit me. i turned the car off and then back on again and the engine light remained on, but i was able to safely get to a chevy dealership. the dealership ran diagnostics on it and they determined it was a faulty gas throttle pedal and sensor. the vehicle was in the shop for a total of two weeks, due to them being out on the parts. i paid over 500 dollars for the repair. less than a week later i was merging on to a highway to go to work again. as i was merging on the engine light went on and the message saying "reduced engine power" came on again. i lost the ability to accelerated and pulled over. i then turned my car on and off again. the engine light remained lit and the "reduce engine power" message remained on this time. i was able to accelerate to a max of 35 mph this time. i returned the vehicle to the same chevy dealership. they ran diagnostics on it and this time they stated it could have been due to the cold weather and said a oil change might help. the oil was changed on the vehicle and then the called saying the vehicle was running very rough when they started it. they also then stated that there was condensation in the radiator from the coolant. they are still waiting for parts and the vehicle has been there almost three weeks. total time in the shop was 5 weeks out of 6 weeks.

When i was pulling out of my driveway, my car stalled. the check engine light came on. i went to get it diagnosed at autozone and the code p2097 came up.

I have a recurring emission issue diagnostic test code p2097 general motors has admitting to not knowing what is wrong with my vehicle. i purchased the vehicle brand new the emission issue is ongoing recurring and my vehicle is up for state inspection for which it will not pass, this issue began at mile 3007 i've owned the car for less than 2 years. the vehicle came without air conditioning for which it was equipped that issue begin at mile 598. i have had multiple systems issues. i have lost my job over this car this issue has not been corrected with several attempts to repair it. i want general motors to repurchase the vehicle with no usage being charged. this has been an issue that is caused my personal life and my professional life severe distress. i literally have lost everything after having lost my job over this defective vehicle. the vehicle had an accelerator pedal assembly replaced which prior to that my car was going into limp mode / safe mode constantly. this is an issue general motors is aware of and has continued to sell this model vehicle with its known defects which in my opinion is extremely dangerous given the resulting characteristics the car displays once going into reduced engine power / limp mode this would occur while driving on the highway early morning late night hours i would have to pull over unexpectedly and suddenly, unhook my battery terminals and reset the computer manually. it would happen on side streets, on main roads, sitting in rush hour traffic, etc. at one point my car began displaying characteristics of losing power steering, engaging the auto stop/start function and not re-engaging the vehicle upon acceleration for which it was intended. i lost power steering in a turn one time and almost crashed in brookline massachusetts a heavily travelled pedestrian area

Tl* the contact owns a 2017 chevrolet malibu. the contact noticed water entering the vehicle and the interior of the vehicle was wet. the vehicle was taken to autonation chevrolet northpoint (2175 mansell rd, alpharetta, ga 30009, (678) 601-2485) where it was diagnosed that water was entering the vehicle from the rear tail lights and the dome light inside the vehicle. the vehicle was repaired, but the moisture caused the windows to fog. the vehicle was taken back to autonation chevrolet northpoint, but the cause of the failure was undetermined. in addition, the gear shifter failed to engage in park and the contact had to force the shifter into park. in addition, there was an abnormal noise coming from the gear shifter. while the vehicle was at the dealer, the technician replaced the instrument cluster with a 2018 part that was not compatible with the vehicle. the vehicle was not repaired. the manufacturer was not notified of the failures. the approximate failure mileage was 145,300.

I purchased a 2017 chevy malibu last week. i was looking over the data on the chevy website. chevy is listing two different hp ratings for this car. one area states 163hp & 184 lb-ft torque. the other says 160hp & 184 lb-ft torque. the main issue i have is with the transmission. gm says the car comes with a 6t45 transmission. that transmission is rated at 215hp & 232 lb-ft torque. enough for the rated engine. the transmission in the car is a 6t40. rated at 180hp & 177 lb-ft torque. the torque on the motor is 184 lb-ft at 2500 rpm to 3000 rpm. i work and live in phoenix, az. 95% of driving is city driving. i am past the max of the transmission most of the time. this transmission will fail very fast in this heat. plus the epa fuel rating i'm sure was calculated with the transmission advertised by gm not in the car. i own a car that is not at all what i thought it was.

After much research i have found out that the transmission that is in the 2017 malibu, which is the 6t40, is not rated to be in this vehicle. the 6t40 is rated at 177lb-ft torque, the malibu has 184lb-ft. gmauthority.com/blog/gm/gm-transmissions/mh8/ this link is the page for the 6t40. however, the 6t45 is what should be in the car, http://gmauthority.com/blog/gm/gm-transmissions/mh7/ this is the link for that one, as you can see the max torque is 232lb-ft. http://media.chevrolet.com/media/us/en/chevrolet/vehicles/malibu/2016.tab1.html their website also says that the car should have the 6t45 transmission in it. the car is brand new so the only thing i have noticed is hard shifting, but in the future i feel as if this could become a problem. i have talked to gm and they said they are the same, but as you see they are not the same. if this post needs to go somewhere else please let me know, i just want to stop this before it starts.
