I have been driving a used 2020 Chevy Malibu LT since October 2024 and I just had my first major issue. I was hoping that someone in the Sub Reddit could give me some insight so that I had a better understanding of my issues when I speak to the mechanics at the Chevy dealership.

I was making a day trip a few weeks ago to a town about 2 hours away and during the last 15-20 minutes of my drive, my car stated stuttering and repeatedly turning my cruise control off. After the third attempt to go back into cruise control, my check engine light came on and it remained on for the entire trip. I had the car diagnosed at an Auto Zone while I was there and they said that there was an issue with my Power Train System. I started getting a “Service ESC” notification on my way back home and every time it would come up, my traction light would turn on.

I noticed something while I was waiting for the service appointment I had last week. The lights would only turn on when my car was nearing a quarter tank and would usually turn off after I refilled my tank. It would also start to get a little shaky when I started going over 55 if I wasn’t releasing the gas pedal as I was accelerating.

Last night I was driving around town and the check engine light and “Service ESC” notification came back. The video was taken this morning while I was driving on a full tank.

I’m aware that Chevrolet has released a statement regarding multiple Chevy Malibu models from the early 2020s having ESC issue but I don’t know if the codes that came up on my car during my last appointment match the ones they released the notice for.

2017 that makes 26 psi of boost. Intake, blowoff valve, and Wastegate actuator are tight and working properly. Pulleys have been lubed, and I don’t see any disconnected hoses or broken ones. Idk

Hey everyone! I recently installed a new aftermarket head unit in my 2014 Chevy Malibu LT. Everything is installed correctly and working perfectly, except for one issue: my A/C is stuck in ECO mode.
As you can see in the photo, the A/C icon is green, indicating ECO mode. No matter how many times I press the A/C button, restart the car, or change the CANBUS settings, I cannot get it out of ECO mode.
Everything else on the head unit seems to be functioning normally. The issue only started after installing the new head unit.
Has anyone with a 2014 Malibu experienced this after installing an aftermarket head unit? Is there a specific CANBUS setting, wiring connection, or setting on the head unit that I need to change?
I’d really appreciate any help or suggestions.

My 2017 chevy malibu has positive pressure followed by wispy smoke.
Context: recently my engine overheated mid driving home because my serpentine belt came off due to water pump pulley breaking. i replaced the water pump n belt n now theres a blowby i think thats what that is called coming from the oil fill cap. Ive done compression tests on all cylinders n they seemed in line and good. i changed out the three outside pcv valves and hoses and i am still getting this issue. i could be wrong but there is another pcv valves inside the cover could that one be causing it?
