High pressure fuel pump blew out while driving on the highway going to Minnesota from Illinois. Fuel was spraying onto the engine and leaking onto the ground. I immediately pulled over and stopped the car, turned off the engine and raised the hood. The car was taken to a Chevy dealership today and I was informed that the high pressure fuel pump literally "blew out." This could have resulted in an engine fire and fortunately that didn't happen. Online research reveals that Chevy had a recall on some 2016-2018 model Malibu's for this very reason.
2017 Chevrolet Malibu fuel system complaints
Page 2 of 3: complaints 11 to 40 of 60, newest first, as owners wrote them.
The warning light comes on and off and is showing (P0498/P0449) which is the evaporative emission system vent control electrical circuit signal has low voltage for a predetermined period of time. Its calling to replace the evaporative emissions canister vent solenoid and I have seen 3 vehicles the same as mine needed the same thing fixed. When the vehicle is in park you can feel it jerk and also while pressing gas when you pull off it stalls. When cranking you can smell fumes .
On numerous occasions while driving on highway my dashboard will display reduced engine power and engine light comes on. My traction control light also comes on. Car loses power quickly and will not accelerate. I’ve had to pull over numerous times almost being hit by cars behind me. Took it to get repaired and had to have fuel pump replaced as wires had melted to side of pump. Three months later same problem happened. This car is scary to drive
In February 2023, we took the Malibu into the dealership for reduced engine power dashboard notification. Light went off when in shop, got the car back and light on once again. When at a red light that turned green, accelerated but car would not go over 20 MPH. Almost rear ended. Dealership replaced the vacuum pump gasket and seal. Fast forward one year later. Once again, reduced engine power notification came on again. Once again at red light, when light turned green, car wouldn't accelerate and was very close to being rear ended and difficult to make it through the intersection. Currently at dealer (1/18/24) with dealer having no idea what is wrong with car (today is 1/24/24). The dealer today stated it will be another 1-2 weeks. That will make it three weeks for a diagnoisis. With reduced engine power, it is very dangerous to drive a vehicle like this. Of course, there are hundreds of other complaints for this issue/make/model.
Issues with fuel pump. Other 2017 Chevrolet Malibu's already have this recall
Issues with fuel pump
bought this kind of new and while still under warranty reduced power engine light came on & engine is reduced to 20 mph have to pull over shut it off wait a few minutes and start it back up and then it will be all right for a while we called dealer made an appointment but by the time the appointment came around the light had gone out they said the light needs to be on in order for them to diagnose the problem the light goes off after about 50 miles after this happens so we could never get it into them within that 50 mile time frame we gave up after a while now it's happening more often and I hear that maybe a class action suit coming they don't seem to be able to solve the problem. we still own this 2017 Chevy Malibu and it is still doing it today.
So basically when I'm driving it automatically I don't know where says engine power reduce which cuts the power down when you're on the highway and see if you're doing 70 miles per hour and all of a sudden that light comes on your check engine light comes on and it reduces the strength of the vehicle so ithe vehicle so we can cause multiple accidents
When vehicle is engaged in auto stop, it stalls out completely or bucks forward when at a complete stop(sign or red light). Upon review, two mechanics stated it has to do with the transmission and tork converter. Repair is upwards of $4000-$6000. 2017 Malibu has less than 75000 miles. Will be contacting dealership today 4/10/22.
The contact owns a 2017 Chevrolet Malibu. The contact stated that while driving at 60 MPH, the accelerator pedal sensor failed with the check engine vehicle entered reduced power mode, the vehicle independently slowed down as the contact pulled to the side of the road. The contact was able to restart the vehicle and took the vehicle to a dealer. The dealer informed him warning light and several other unknown warning lights illuminated. As the that the accelerator pedal sensor was defective and needed to be replaced. The contact was also informed that the parts to repair the vehicle were unavailable. The contact then had an independent mechanic replace the accelerator pedal and the sensor. The contact also stated that while merging onto a highway at 60 MPH, the vehicle stalled with several unknown warning lights illuminated. The vehicle entered reduced power mode as the contact pulled off to the side of the highway. The contact was able to exit the highway and drove the vehicle slowly back to his residence. The following day, the vehicle was towed back to the dealer where he was informed that the high-pressure fuel pump failed and that the vehicle was not included in the federal safety agency Campaign Number: 18V358000 (Fuel System, Gasoline). The manufacturer was not notified of failure. The vehicle was repaired but remained at the dealer. The failure mileage was approximately 32,000.
My 2017 Malibu suddenly had the "check engine" light come on, and a message indicating that a "reduced power mode" had been initiated. I drove the car immediately to the local dealer, who said I needed an appointment to have it checked. I checked the OBD2 codes with my personal meter, which showed a p2138 code, indicating a problem with a throttle body sensor. When I started my car the next morning the MIL light didn't come on. At the dealer I was told they couldn't do anything with the car because the light wasn't on. I pointed out that the failure codes were stored in the ECM, but they said diagnosis wasn't possible with the light off. The service writer indicated the problem was not uncommon on GM cars and that even his wife's car had similar problems. When this occurred I was fortunate to be on a local suburban road where reduced speed was not that great of a problem. Much of the time I am on freeways in several major Midwestern cities where aggressive drivers are packed together. I read a number of complaints on the federal safety agency site indicating same complaints from Malibu owners. A sudden reduction of speed in a congested area is a recipe for disaster. The service writer even stated that GM had an extended warranty on the pedal assembly and TPI sensors. But he refused to try and diagnose the issue, unless I brought the car in immediately if and when the MIL light was illuminated, even if I was 500 miles away. As this intermittent behavior is a known and common issue I feel that GM should be compelled to do something to correct these defects before a truly dangerous incident occurs, causing devastating results. But I'm sure that this will go on until misfortune causes those in power to ask. Why didn't somebody do something?
I have a 2017 Chevy Malibu, I have 10 months with me since I bought last year ,it and it was 25000 mille now is 30000 m my real problem is on several times driving in freeway or hiway my car drop the speed from 55 to 40 to 20 and appear a light says POWER ENGINE REDUCED , after that my car LOOSE POWER - CHECK ENGINE IS ON I got nervous for what happens and is really confused I just buy my first car from dealer and now this !!!!

Engine Power is Reduced
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 about 46,000 miles and is well maintained . Our safety was at risk both times but especially the first time as we were in traffic and speed declined .
I was going 70mph on the highway, when I got a sudden alarm from the car saying "reduced power". The car would not accelerate and started slowing rapidly, almost resulting in a collision. The car would not go more than 20mph. I had to pull off to the shoulder, restart the car several times, and then was able to get the power to come back, but the check engine light remained on.
While driving received recurring check engine light for p2127/p2138 code. Has been to Quirk Chevrolet twice previously for same issue, drives fine for a week or two and light comes back. Third service appointment scheduled for Monday 6/7/21. Recurring issue has made vehicle unusable while effected as car goes into limp mode while in motion limiting speeds to 25mph which was interesting to say the least as it happens while in motion.
OBD2 codes ran on vehicle show: P0138 ("O2 sensor circuit High voltage bank 1 sensor 2") P013E (unknown) P2138 ("Throttle/Pedal Position Sensor Switch D/E Voltage Correlation") Vehicle is getting poor fuel mileage and has a drastic delay in acceleration after pressing the gas pedal, putting driver in immediate danger in traffic.
While driving on multiple accusations my engine light would come on and go off within minutes and not return till I turn the car back on or while driving later on in the day or days after seeing the light come so I was unable to bring it in to get checked out properly. A month passed when the issue appeared and when I decided to go into the dealership to possibly trade in my car the light was not appearing for days beforehand and things were normal till a a couple days after I left the dealership my car read on the dash 'reduced engine power ' I wasn't able to accelerate quick enough in the middle of traffic on military trail and belvedere I had to pull through a walmart parking lot to avoid on coming traffic and bring the car to my home close by very slow and sluggish due to not getting any acceleration from me pressing on the pedal. The dealership wants to replace my fuel pump system at a cost however it has a current recall for my specific make and model.
I purchased the vehicle in 2018 with 20,000 miles on it. My check engine light has been on more than 7 times in the past 2 years. I had to have the fuel injector worked on, sometimes it won't shift completely into park, I had it decrease in speed from 70 on the highway to no more than 20 MPH with over $400 in repairs just that time. I do not drive fast or deprive my car of regular maintenance. I have never had issues like this with any other vehicle.
As I'm driving down the highway, trying to accelerate, a reduced engine power light comes on and my car will slow down to 20 MPH. I have to shut my car off to get it to accelerate. It is doing this on a regular basis now.
Check engine light and reduced power message diaplayed.
Vehicle has several recalls
Fuel tank will not fill completely. It will only fill to 7/8ths at best. There are other complaints about this in online forums.
Vehicle will shut down after auto stop enabled when car comes to complete stop at lights, intersections, etc. Vehicle will also shut down while driving. Stalitrak warning blinks but the electrical power inside doesn't always shut down. Car will start back up once you quickly put the vehicle in park , shut it off and then turn it back on. Sometimes it takes 3-5 times to get it started back up. Battery has been changed and sensor replaced but it still hasn't fixed the issue. Severely uncomfortable driving the car anywhere.
My power steering assist pops up and disappears. Car completely shut off on me at a stop sign(twice) and would not crank back up
Whenever I fill the take from e I have to at least refill an additional two times per week. The gas goes really fast and I can't even get 13 gallons in my tank.I get about 21 mpg every trip.
Tl* the contact owns a 2017 chevrolet malibu. The contact stated that while driving at various speeds and while idling, the vehicle stalled and shutoff without warning. The contact stated that they would have to wait for approximately 15 minutes or more before the vehicle would restart. The contact took the vehicle to five star chevrolet (2199 david h mcleod blvd, florence, sc 29501, (843) 605-0183) however, the mechanic was unable to identify the cause for the failure. The contact stated that onstar diagnostic tool showed a failure with the engine, transmission, and fuel system. The vehicle was not repaired. The manufacturer was made aware of the failure and informed the contact that the vehicle was not subjected to a recall. The approximate failure mileage was 40,000.
Everytime I stop at a red light or brake the vehicle(when coming to a stop in traffic)the car completely cuts off.the alert steering assist is reduced, drive with care constantly comes on whenever there is an auto stop and the car restarts. The radio and air would also turn off when auto stop is activated. This turn off also causes the radio screen to go black for a short time until it restarts. Which is a big problem and dangerous when driving in traffic. The normal auto stop would be somewhat silent, but when it turns back on now it hisses and turns back on. I also hear something as if water is passing through pipes after and/or during auto stop sometimes. Lastly, last night(7/8/20)I attempted to turn on my car and back out of my driveway. The car turned on but the check engine light came on. It did not allow me to shift into any gears or accelerate. I noticed the lights that illuminate,d,r,l,etc. Was not illuminating at that time when I attempted to shift gears. I then turned the car off but it stated shift to park. Note the car was in park. After I let it sit in park for a while I tried restarting the car and it restarted. The car shifted in to gears and accelerated. Note: the car allowed me to move the shift in and out of gears but it was not catching. The stopping issue wit the steering reduced alert started about two weeks ago(around june 25,2020). Hearing the water sound began around the the beginning of march 2020. Lastly the shifting issue began last night,7/8/20. When driving on the highway I do the speed limit 60-70 MPH. On the city streets I drive the speed limit ranging 25mph-40 MPH.
My chevy malibu has stopped several times on the highway more often durning traffic time it always stops when it enters auto stop then it cuts all the way off and I have to restart it I called in about this last year . Also it makes it really tough to push my breaks when I start the car up it does make the sound like it wants to start then it dies out
As I was driving on the interstate my check engine and traction control lights flashed on. All of a sudden the engine power down light lit up and I couldn't go above 30 MPH. This has happened twice in the last week. Very scary when you are driving 60-70 MPH on the interstate.
