Toyota dealership messed up my GR86 during an oil change.

[edit: last update was that it’s a vacuum leak resulting from their inspection]

Anyone had an issue like this?

Bit of a vent while waiting to hear from the manager. I went in for my third oil change at 9500 miles. Yes, early, besides the point. Zero issues up until it was in their possession. I check the oil regularly, let it warm up before pushing it, etc.

When they were finished, I went to take off, and the car would not idle. I turned it off right away and went back in. Eventually they got a tech back out to take it into the garage. He barely got it into the garage without it dieing.

They told me it may be the oil cap not being tight enough, but apparently that wasn’t it. They didn’t have a diagnosis yet before I had to leave with a loaner. It didn’t seem to be a priority for them because it was sitting back out in the lot when I left.

I’m worried by the way the service manager spoke that they’re going to try to skirt responsibility. Now I’m stuck driving a boring 4Runner until I hear back. I have an event this weekend I planned to bring the GR86 to, but might not be able to. I don’t care much about that, I just want a car that runs. I’m concerned that whatever they did might be fixable in the short term, but there could be damage to the engine that shows up down the road.
