1. This case refers to a 2018 Chevy Malibu. In October 2021, the (gear shift) transmission control system was found faulty and was replaced with an N-CONTROL in the gear shift. Again, in September 2025, the same issue happened, this time replacing the N-CONTROL again as well as the N-HARNESS. Yes, can be available upon an inspection request. 2. This component directly affects how the car recognizes when it is in Park.

When the car is shifted into "Park", then I attempt to turn the car off, the car turns off partially, but the electrical system stays on and a message saying "! - Shift to Park" appears on the screen. The car cannot be turned off or locked, and it takes multiple attempts of fulling restarting the car (so the shift interlock system unlocks) and shifting gears until the vehicle recognizes that it's in park and will allow itself to be turned off fully. This issue takes at least a few minutes per incident to resolve. If it's not resolved, the car cannot lock and the battery drains.

I have an ongoing issue with the shifter not communicating to the ECU that it is in park. I put the car into park, dash board shows in P (park) and transmission is in park (ie won't move forward with brake released) and when I go to turn the car off I get message that car is not in Park. To remedy this I have to smack the back of the shifter forward sometimes 5-15 times and from light to moderately hard pressure to get the ECU/sensor to realize it's in Park. The shifter was replaced by a Chevy dealer 2-3 years ago but the problem started again.

My car keeps saying “shift to park” when it is already in park. I have to keep turning the car back on and off numerous times and shifting the car into another gear and back into park and wiggle the shifter to get it to read that it’s in park. I don’t know if the car is actually in park or not and will roll if I leave it. Also by turning the car on and off multiple times, sometimes 7 to 8, will ruin the starter or cause some other issues. I have not taken to a dealer yet because online reports of same issue in multiple gm cars have said they are replacing with the same faulty part.
