Have a Mazda 6 that continuously has the check engine light come on. Had an incident where the car was failing to accelerate and waited for tow truck. That was the first time I took the car in for repair. Waited 3 weeks before I could get my car back and when I got it back, it happened again 3 more times, and took it in for servicing all those times. I don't want to continue to make a trip to the dealer every month like I have been doing.
