No. I have a 2012 Mazda3 5 speed that I just rolled over 300K. Only thing I’ve had to replace that wasn’t a wear item was an alternator.

The 2.0 is kinda gutless but its good on fuel. That is literally my only complaint with the car.

My gf has a Subaru Crosstrek. If you were looking AWD I would definitely cross shop one of those. Its a nice car.

Unfortunately you can’t afford to not fix it either. That car is worthless without a motor. If Mazda isn’t covering the replacement then it’d be a cold day in hell before I would get the work done at a stealership. Look for a motor at a junk yard and get a mechanic to drop it in and put a for sale sign on it.
