My wife took her 2006 Scion xB in for an oil change. She picked it up last night, and as she turned onto the road she noticed the red oil light came on. She went back and told the night guy, who told her that she’d have to come back in the morning. She then drove to the store, and the car started making weird noises and she started heading back to the garage. Part way there she stopped (I’m not sure why), and I told her to call AAA. The tow truck driver reached underneath and touched the oil filter and it fell off. There was no oil left in the engine. We went back and saw the oil tracks leading out of the garage. In total, she drove about 3 or 4 miles without oil.
We talked to the garage this morning. They said they’d cover it 100%, including put in a new engine if necessary. But two hours later, they called and said that they put in oil and turned it on, and it seems to be running fine. Also that they’d guarantee it for 1 year. I asked them to a compression test, but haven’t heard the results yet.
So my questions are: What shape can I reasonably expect the car to be in now? And how can I figure this out? What options do I have if the garage insists that the car is fine?
