My car was running fine until recently, when I had a few services done at the dealership: brake fluid, transmission drain/fill, oil change, and fuel injection service (this last item I did not ask for or approve beforehand). A couple days later, my car began stalling when I was driving (while coming to a stop/ not pushing the accelerator). No cel / overheating/ low oil issues- always regular maintenance. Took it back to the dealer, they said the engine had low compression and they suspected a cracked engine block. They also checked to see to see if my ecm was updated. That was all they said after being there 5 hours. I had to leave for work, brought it back a few days later, they said they didn't have time to look at it without an appointment. A few days later, my car wouldn't start at all. Took it back in, they said they didn't know why it had low compression/ stalling/ not starting because no oil or coolant leaks or mixing, no overheating, etc. Told me the only option is to replace engine. (cost of tearing engine apart to find crack or cracked gasket not worth cost in labor because of car's age/ mileage- 2009 Corolla, around 176k). How is this even possible? I suspect that something was not done correctly during a recent service, or maybe they did not update/flash my ecm correctly. Of course, they are not claiming any responsibility. Very frustrating. The dealership manager did offer me a discount on the used engine repairs, but this seems like either manufacturer error or technician error.
