2021 Chevrolet Malibu ELECTRICAL SYSTEM,UNKNOWN OR OTHER,ENGINE

I was driving the car on the highway and “SERVICE ESC” popped up on my dash. Engine power reduction kicked in which caused me to have to erratically pull over to the shoulder. Brakes did not engage properly. When the “Service ESC” warning comes on the dash, the engine, transmission, and brakes stop functioning properly. The gauges start fluctuating up and down and the gps goes out of whack. Transmission won’t shift gears and the car will sometimes shut off all together.This is a very common problem with the Chevy Malibu from 2017 to present. I did my research and there is a lot of disgruntled owners that have experienced this problem. Type in “service ESC Chevy Malibu” on google, Reddit, or YouTube and you will see. I personally know two other Malibu owners with the same issue different years and mileage on there Malibu. I honestly can’t believe with all the information out there on these Malibus having the same issue there has not been a recall yet!

I own a 2021 Chevy Malibu and I have been having issues with my transmission since November 5,2024. I was driving along at about 30 miles per hour When all of a sudden the car would not accelerate so I put the car in park and put the car back in drive and accelerated but only revved up but still would not move. I called a mechanic to look at my vehicle and he checked that I had transmission fluid and it was full. Upon further inspection he plugged an OBD code reader on my vehicle and came up with a P0700 Transmission Control System Malfunction which is the output shaft speed sensor or the vehicle speed sensor? I spoke to a shop about the problem and they said that that year and model car has a lot of complaints from owners. They said that it could cost up to 3,000 and up to replace the transmission. I think that it should be investigated for that issue?
