The car has only 41k miles on it and the engine warning light came on. I had the car towed to Mazda and now it won’t start and it needs a new engine. (Which is on back order for months). It is covered under the powertrain warranty but does me no good if I’m without a vehicle, and making car payments on a vehicle that isn’t running.
