NHTSA Complaint #11512888 — 2016 CHEVROLET SILVERADO 1500

The lifters on one side of my engine failed. This is due to the AFM(Active fuel management) system that GM had in its vehicles from 2016-2021. My truck is a V8 motor and the AFM system drops the motor to 4 cylinders during periods that the vehicle is in stop or coasting. Overtime the lifters in the engine wear out causing the engine to fail. I barely made it to the dealer to fix the issue as I lost full power in the engine nearly causing me to have an accident. The only notification I got was check engine light started blinking mid-stream on my way to work. The cost to repair lifters is extremely high and that is the reason why GM hasn't issued a recall yet. There are thousands of cases of failed lifters in my research online. GM knew this was a problem as they have quit using the AFM feature in all of their vehicles. My servicer at my dealership even told me that they have seen this problem on multiple occasions.
