Hello everyone, I've got a 2014 CX-5 I've always taken it to tires plus for service in the last month I've had to go back and forth more than I wanted to.
The car is reaching its 100k mile mark the check engine light came on, they told me I needed a tune up which I knew i did and the code reader also indicated the mass air flow so I did them both.
Check engine light came back on, it indicated a gasket leak in the exhaust (the gasket is a dealer part on).got that done Check engine light came back on code reader indicated the o2 sensor that's been changed. And now the check engine light is still on and I might have to take it back to the dealer cause I was told that it may be the ECM.
Does anyone have any guidance they can give.

Thanks.

 

What actual fault code/codes are you getting?

The dealer has the factory trained technicians, with the factory scan tool, factory service manual & factory technical specialist support call centre.
