You are talking non-sense. My father had the theta 2 replaced under warranty. Rental covered for 3 months. No issues at all with the process and they were easy to work with. Stop spreading fud.
Turbo cars can be as reliable. I have a Hyundai with 60k miles not a single problem.
My Mazda was literally the worst experience. Engine mount broke, later was recalled. Constant suspension issues. Rust. Absolute piece of shit.
Their reliability appears to be better now but I’ve been burned.
That car was so junk I promised I would never buy another Mazda again. Absolute garbage of a car.
