Breaks suddenly failed I have researched this problem and it is a ongoing problem with the vacuum pump and Chevy knows this
The contact owns a 2017 Chevrolet Malibu. The contact stated that after his wife parked the vehicle, the "Shift to Park" message was displayed while the gear selector was shifted into park(P). The vehicle would not turn off until after several attempts; however, the failure recurred with the doors locking the contact's wife and 3 children inside of the vehicle. The contact's wife was able to turn off the vehicle while the brake pedal was depressed and the Start/Stop button was pressed and unlocked the doors with the key fob. The dealer was made aware of the failure and sent a tow truck to retrieve the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 57,733.
When stopping and vehicle is in park, it will not let me shut off the engine. Indicating that I must shift into Park, although it is already in Park. I view this as aa safety problem by not being able to properly shut down the engine. The warning chime continues to sound, "SHIFT INTO PARK". tHE ENGINE HASS NOT PROPERLYY SHUT DOWN!!!!
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
After stopping and shifting to park and pushing the "Ignition Button". The button indicator light shows car is not in "park". The dash indicator also states "Shift To Park" even though it is in park. This can be resolved by many pushes on the shift stick lever. It is obvious to be a shabby mechanism inside the shift box that isn't connecting the circuit to show that the vehicle is actually in park. This problem began about a week ago and it seems to be somewhat worse as time goes on. When it first happened, I did not know what to do. Thank god for google that showed me how to "jerry-rig" a fix each time to show it actually in park (flipping the shift stick button). If left alone, I would possibly drain the battery. Also google comments and post indicated this is a complaint by many and should be a considered for a recall.
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
Shifting into park, transmission control assembly. Cannot put the car into park, have to fiddle with the shifter to get the car to turn off, drains my battery. Have to make certain car is off and in park before putting gas into the car. First incident was in April, and now ongoing every time I try to turn the car off. Error Message: Shift to Park
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.
When driving my vehicle at highway speed the vehicle slows down at about 15-20 mph a message on the dashboard states engine reduced power. The first time I was able to get over and cut the vehicle off and restarted it. But the vehicle did it again. The check engine light has been ever since. A few days later the vehicle did the same thing. I took it to Autozone and they gave me a code. Which is for the accelerator pedal sensor and the throttle electrical control. This is very dangerous to be driving at high speeds and all of a sudden the vehicle drops speed to 15-20 mph. I haven’t been able to find any place with the part to get the vehicle fix. Can someone help please?
While I was driving my car went into engine saving mood. My speed was reduces rapidly.
Reduce Power mode continues to come on! This is the 3 winter with it happening.
The shifter will get not recognize it's in park. I will typically have to move around the shifter or force it from low to park multiple times for it to recognize. This has happened multiples times over the past year. I have also read online multiple other chevy malibu owners have also experienced this.
The contact owns a 2017 Chevrolet Malibu. The contact stated while driving at 30 MPH, the "Steering Assist Reduced - Drive with Care" and other unknown warning lights illuminated, and the vehicle stalled. The contact stated that a nearby independent mechanic who witnessed the failure assisted her with restarting the vehicle with an unknown device and assisted the contact with pulling to the side of the road. The contact sated that the vehicle shut-off and failed to restart after several attempts. The vehicle was towed to the contact's residence. The Used car dealer was notified of the failure but did not provide any assistance. The contact stated that the failure occurred the same day she had purchased the vehicle at the Used car dealer. Upon investigating on Carfax, the contact became aware that the vehicle had previously been totaled. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 106,000.
Car dash displays "shift to park message" when car is in park. Unable to shut vehicle off
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 NHTSA 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 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.
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
While driving on highway, engine light came on with signal for service stabilink, and engine power is reduced on dashboard. This cause me to lose acceleration control.
While driving the electronic power steering stopped working almost causing me to crash.
The vehicle displays “Shift to Park”. Cannot turn off car and most recently we needed to turn the car on/off 12 times to get the vehicle to park. We’re worried we will not see the error message and exit the vehicle with the possibility of the car moving as it doesn’t recognize that the car is in park.
Frequently the car will say that the transmission is not in park, but the shifter is in the park position, and the car will not turn off until I take it from park to reverse to park again. Sometimes it takes several tries before the car will register that it is in park.
The vehicle has just over 51,000 miles on it. When shifted to park and turned off, it gives an error message "shift to park" and will not shut all the way off. This requires the car to be restarted, shifted out of park and back into park and shut down again, often multiple times. The car is currently at the dealership having the shifter assembly replaced, which will cost over $600 in parts and labor. Online research indicates this is a common and known problem, with bulletins issued in all 50 states. If the shifter assembly becomes obstructed from proper functioning by debris, as these bulletins suggest, it would appear that this could eventually result in the inability to put the car in park at all, which would be a major safety concern. GM states it is not under recall at present.
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
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 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
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.
The contact owns a 2017 Chevrolet Malibu. The contact stated that while driving at 60 MPH, the "Engine Power Reduced" warning message appeared on the instrument panel. The vehicle independently downshifted and decelerated to 35 MPH with the accelerator pedal depressed to the floorboard. The contact was able to regain normal speed after several minutes; however, the warning message remained on the instrument panel. The contact took the vehicle to the dealer however, a diagnostic test showed no codes were retrieved. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 93,400.

An error message appears on the dash, ENGINE POWER REDUCED. It happen three times this morning and twice yesterday - probably a dozen times over the past year. I've had it into the dealer but they could not find anything by the time I got there. It has happened at 35 MPH and between 45-55 MPH, suddenly and with no other warnings. Turning off the engine for a few minutes clears the message on the dah, but the check engine light remains lit. The check engine light will clear eventually - it may be a few hours or two days of driving. Again, I've had it checked on multiple occasions as the car was "certified" by GM, but now the warranty has expired, the issue continues and I see a LOT of reports of the same online.
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. This is a deadly issue and why there is not a recall is outrageous, There are cars out there that are capable of causing a deadly crash and killing thousands of people and everyone is turning there head when the consumers are reaching out for help.
The reduced engine speed popped up on the dashboard and slowed my speed down to 20 mph in the middle of traffic and it will not correct even though I have turned it off and restarted the engine.

When putting vehicle in park message goes off stating to put vehicle in park you have to wiggle it to make the message go off or it will drain your battery

Engine Power is Reduced
Was driving to work at 5:00 am today and merged onto a busy highway. After accelerating to 60 mph, there was a message that appear on my dashboard that read engine power reduced. It was not safe traveling at the speed that I was. The check engine light came on as well as the Stability Control symbol and my car reduced its speed and would not accelerate back to a safe speed. I am going to take it to the dealership and try to get the problem diagnosed. I really hope this issue gets resolved.
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 .
after 4 years My 2017 Malibu Engine light is on now with power reducing power periodically. Thus is dangerous and was not fixed at the dealer. This is serious. Why isn’t there a recall. I know there is a class action suit. The is not acceptable at all.
I received steering assist reduce multiple times on the vehicle. I took it to the repair shop the warranty company Silver Rock recommended. The repair company stated my car is having a computer issue. The car also does not go into auto stop, when making a full stop. The car now has to be towed to a Chevy dealership to handle the issue.
Intermittent shifts, no reverse, MIL illuminated Happened in rush hour traffic, could not move out of EMS workers way because of reverse failure. Nearly ran into vehicle in front of me due to such harsh sift from 1st gear to 2nd gear. Currently being inspected by local Chevrolet dealer. No warning light when incident occurred, only came on when I was able to turn the car off and back on. Extremely dangerous circumstance that could have easily been prevented had GM issued a recall on Service Bulletin 18-NA-081.
Car voltage stays very high (between 14.8 and 15 volts) for extended periods of time. At which point the windows have fogged up and there is a raw egg smell in the cabin - probably Sulfur. Both the hybrid and the 12v car battery are located in the truck and there are vents that draw air from the cabin to ventilate those batteries. The car voltage will also stay at 12.5 to 12.6 for extended periods of time. During both high and low periods numerous internal systems have failed, including bit not limited to steering assist, anti-locks bakes, Stabilitrack, On star, Hybrid Control Processor and ECM. Car has been brought to the dealer 3 times. First time (early November 2021) it was diagnosed with an hybrid inverter and a software update was installed. Issues continued. As of 12/28/21, Coggin Chevrolet (Jacksonville, FL) has had the car for 2 weeks and can't fix or confirm what is wrong with the car. I have received numerous e-mails from On-star with engine error codes as well as 5 messages saying there is an issue with the Electric Drive Unit in the car. The car has roughly 24K miles on it.
My car shut off when I stopped at a blinking traffic light (normal). There was a higher than normal amount of traffic on the route I was waiting to turn onto. So the car remained off for close to 5 minutes. When I removed my foot from the brake the car did NOT RESTART ON ITS OWN (not normal) and after trying to restart the car manually it still wouldn't restart and I couldn't roll down the driver's window to wave several cars around me at a dangerous intersection. I had to open the driver's door to wave vehicles around me. A message came on on the Driver Information Center (D.I.C.) that read "Stabil" and those are the only characters I could see in the small character box. It took me several tries to rest the car. Very dangerous situation. I will try to contact the dealer about this.
This class action lawsuit was filed in the U.S. District Court for the Eastern District of Michigan by three separate plaintiffs in Wisconsin, Minnesota and Maryland, Car Complaints reports. The suit alleges certain GM vehicles fail to detect when the gear selector has been shifted into Park, blocking the ability for the user to shut the vehicle off. Typically a ‘Shift to Park’ warning message will appear on the driver information center when this happens. The user can jiggle and or move the gear shifter in order to remedy the issue, although this technique does not always work. GM dealer witnessed the problem. MY REPAIR COST AT A GM DEALER WAS $391.11.
I purchased my vehicle in August of 2020, in October while driving down a main highway the engine light came on with a warning that stated "driving with reduced power". The vehicle slows to 20 mph and will not accelerate any faster. I called my dealers service center and was told this issue was a "quirk that happens" and to "turn my vehicle off and start it again" and that by doing this it would make it go away and it would not happen again. Approximately 8 months later this happened again, so I called the service department and was told that a line was freezing and that I could bring my vehicle in so they could empty & refill the frozen line costing $500, but it would not solve the problem, the dealer then recommended that I park in a heated space to avoid it freezing, but again it would not resolve the problem long term. A month later while driving home from work in a blizzard, my vehicle once again lost power, with the engine light on and a warning that I was driving with reduced power and slowing to 20mph. This put myself and other travelers on this busy main road at risk. When I reached out to my dealer they said that there was nothing they could do that would guarantee a fix, but they could try three different options, again with no guarantee of a fix. None of this is covered under warranty and costs roughly $1500.
The contact owns a 2017 Chevrolet Malibu. The contact stated that while she was driving at an undisclosed speed and approaching a stoplight, the brake pedal was depressed, and the vehicle suddenly lost electrical power. The warning message "Steering Assist Reduced, Drive with Care" was illuminated. The contact was able to restart the vehicle and continued to drive; however, the failure recurred increasingly while depressing the brake pedal at stoplights. The dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 83,000.
I was at a red light waiting for the light to turn green like normal I press the pedal the car goes at it's normal pace until one day I was at a red light and when I press the pedal the car suddenly shut off and didn't want to start I pulled over called a mechanic couldn't really describe what was going on at the time but i made a appointment for the next day I started up the car up again and it drove and when I reached 30 mph the dashboard flashed engine speed reduce so I took it home and didn't drive to the morning to the mechanic he change a variety of things battery, alternator,sparks plugs, throttlebody ,and mass airflow, and nothing work I finally took it to a dealer and the dealer said it's turbo bypass valve or the actual turbo they don't know which it's either you buy the part and see if it fixes the problem and if it don't buy a whole new turbo
My vehicle has recently displayed a message telling me to “Shift to Park,” even though the vehicle is in park. On 10/06/2021, twice it took 15 times shifting to get the car to go into park. Now, it does it every time I put the car into park. Have an appointment to take it to Jim McKay chevy in Fairfax on Tuesday.
