We had the same problem today actually. No previous problems. Took the car in for an oil change, drove out and check engine light came on, engine sounds like its gonna blow up at start, breaks dont work, etc. Idiots. Before we picked the car up, they called to ask about replacing engine air filter, told them yes - they realized they didnt have a filter and had to order one and forgot to put hoses back on and didnt put air intake sensor back on. I guess I'm wondering if this can cause potential problems down the road - I'm not picking the car up for us to pay for their mistakes later.
did you try unplugging car battery for ~5min too?
