I have a 2016 Chevy traverse with 80,000 miles on it. Driving the other day it the tranction control light came on( it said off), and it said service stability track, and then it went into engine reduced power.and check engine light was flashing. It was not drivable. I had it towed. P0300 showed up on my diagnostic machine. I replaced the spark plugs, checked the coil packs (they were fine) and I replaced the o2 sensors (1 upstream and 1 downstream) and nothing has fixed it. It will be going to a shop but I just want to know if anyone else had this issue.
