Interesting first post.ToyCar Care poured oil all over the engine of our GX470, to the point it was dripping off the skid plate on onto my garage floor. Wife took it back, they wanted to charge us for them to clean the oil up and see where the leak was. Which was ridiculous as there wasn't a leak at all, it was their gross incompetence at doing a basic oil change.
At that point I started doing all the work on that rig myself. Dealers are for warranty work and work I don't want to do, otherwise I wrench on it.
I do our own oil changes. I have taken it there for Tranny flushes, steering rack replacements, riming belt and water pump and have had zero issues over 14 years. Sorry for your experience, like the dealership they don't put master mechanics on oil changes I am sure, but they should have taken care of it for free. Everyone makes mistakes, its what people do about them that sets them apart
