While I was driving my car went into engine saving mood. My speed was reduces rapidly.

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 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 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

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.

Engine Power is Reduced

- Wayne City, IL, USA

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.

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.

My vehicle has been flashing the Shift to park warning for about 2 years now. It never happens when I take it in but I have made dealership aware.

STEERING ASSIST REDUCED DRIVE WITH CARE message comes on car screen. The steering wheel jerks and acceleration is reduced. This is putting everyone in my car at risk as we are not able to accelerate fast enough if anything were to happen. Car has been taken to the dealership and they are unable to identify the problem. I checked online and multiple Malibus are having this problem. If you're looking for a safe car for your family member this is not the car. These cars have these errors built in the system and the dealership are unable to find the problem costing a lot of money on diagnostics to get no results. Please notice all the complaints I hope my word is heard. If mine is not heard I hope the next persons will be.

I get a -??Shift to Park-?? message when car is placed in PARK and turn off ignition. This is not covered under the bumper-to-bumper warranty since it is over 3 years old, but I only have 28,800 miles on the car. This shouldn-??t be failing after so soon. This happened about 2 years ago, but it stopped and has worked fine for two years. Now it's back and won't go away. There seems to be no way to shut off the car unless it is in PARK. Until I an able to get it fixed I am concerned it won't shut-off one of these times, and what happens if it won't shut-off? None of the options are good if I'm driving after hours and the dealer or service center is closed. This can easily turn into a dangerous situation. (Repair is scheduled for next week.) This seems to be a common error reported on many 2016 through 2020 Chevrolet vehicles. There are service bulletins with regard to this problem. Why has Chevrolet/GM not had a recall for this widespread issue of a faulty micro switch?

2017 Malibu with less than 36000 miles, complete shutdown of all power. Engine auto stop shuts down engine but does not restart. Have sat in traffic for 15 minutes or longer before the engine would start. When restarted there is no volume on the radio. Has happened 10 to 12 times in the last 2 months. Dealership said they could not recreate issue and gave a load bull as to why it may happen...

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"!
