well with my first Supra, i experienced that at Jiffy Lube.havnt been back sense.they offered me all sorts of free crap after they didnt tighten my drian plug and i leak out all the oil that was put in. After working for Kuhn, i ca trust a Dealership none the less, plus i ask them if i can come back in the shop while they work on it, they dont have any problem letting me do so
