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.

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 .

Throttle Position Sensor is falfuctioning. Class action law suit against this already. Chevy Malibu Class Action Lawsuit is Hutchinson v. General Motors LLC, Case No. 8:19-cv-01551, in the U.S. District Court for the District of Maryland. Vehicle decelerates at highway speeds down to 20 mph and engine power reduce comes across the screen. Has almost caused me to be in three accidents. Need to recall all malibus and have this part replaced before someone is killed.

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?!
