Having doubts!!

PROS
Fuel Economy

The diesel engine burns slower and lasts a lot longer than the gas engine SLT I previously owned.

CONS
Reliability

The check engine light came about a month after getting it, and it has been to the shop four times for the same issue. I'm starting to think that instead of doing all that is needed to get it fixed, minimal repairs are made to get the check engine icon to reset. I have called the dealership on 2 occasions to speak with the sales manager about my issue, but he never returned my call. Even though I didn't buy the vehicle from his particular dealership, I assumed he would want to hear my concerns.

Unable to install a new radio with Sirius. None are made for 2020 models.

Fuel economy is to be expected.
