Got a oil change about 2 months ago and the tech noticed the rear end seal was leaking so I dropped it off at the dealer the next day and had it replaced.
Fast forward to two weeks ago it started grinding and humming like a turbo, long story short it's been in the shop for two weeks and the tech called me today telling me they can't find the parts to fix it. I told him to go look out in the parking lot you have plenty.
I bet 20 bucks that they didn't put fluid back in it when they replaced the seal.
What would you do in this case, pretty sick of it right now
