So I have a brand new 21 trail boss and I’ve had 4 check engine lights come on. First 2 we’re misfires in cylinders 1 and 6 but they couldn’t track what it was because the codes were stored because the lights didn’t stay on. The 3rd came on 4th of July but said it was to update ecm. Then the day after it came on for a 4th time and it stayed on solid check engine light. Took it in and they said they found code p0300. They performed crankshaft variation relearned procedure and cleared code. Told me to report back if it happens again. How many more times until I can get a lemon law involved. This probably is getting old on a brand new vehicle. Any suggestions? Anyone having the same issue with these vehicles?
