Sounds like the bolt was cross threaded, maybe.
Did you have this work done at an independent shop or a dealership?
it was done at the dealership, had service up till 55k miles . I was checking how easy it would be to do oil changes and if it could be done without ramps and notice the bolt. Still debating if I'll do the service , shop prices range from $59 to $110, dealer is at $89 (probably cheaper with specials). My cost is probably $50-60 for parts.
