(It was in for other service and they told me an oil change was SOP replacing an intake gasket) They told me fine; they would put a mechanic's lien on the car and keep it. I threatened to call the police, they offered to hand me the phone. If it was up to me, I'd NEVER own nor drive a vehicle under warranty, the dealerships are honestly too greedy & stupid.
I grudgingly paid my bill, then I spent $200 on a custom locking oil cap. No one since has attempted to change my oil. Of course, I no longer patronize any stealership.

I can tell you several nightmare stories about friends cars at service garages, including stealerships.
I had a similar experience with the Ford dealership doing my 6.0 PSD work van-they drained the Premium Blue Extreme 5W40 (even though it wasn't due AND I left a post-it note on the steering wheel & told the advisor NOT to change it) & put 15W40 in it. Of course they left it outside, & being winter, it dropped to 30F. Got to prove to them that it needed syn-it romped, smoked all over, sounded like it was trying to hydrolock. Needless to say, that was an expensive attempt to rip off a customer, they had to order & put the 5W40 back in.
