While driving the vehicle, I started smelling a burning smell about 10 days ago (2/17). I also felt a slightly reduced engine performance and could see the car emitting smoke from the engine bay. I had no warning lights on my dash. For all I know, the engine could’ve blown while I was driving on the road. Upon taking the vehicle to the dealership 2 days ago (2/25), they informed that my car has a cracked cylinder head, and there was no apparent reason why this would happen. The vehicle has only been inspected by the dealership thus far and I was quoted $5,700 to fix the issue. Upon looking up the problem, I see this is a common issue, with many having experienced it before, but no TSBs issued for this. There is a CSP issued for vehicles of the same year, but limited to the Turbo version on the engine. Unfortunately, I do not have any warranty on the car currently.
