My car was having an odd issue. It ended up being a major component in the transmission. FORTUNATELY, it was still under warranty, so the dealership and main company paid for it all. It took them four days to get the part in and my car fixed, and I had a loaner the whole time, all fully covered.
They get done, I go in and get my car, I start pulling out of the parking lot… and I immediately swing back around to the service area.
Me: “Heyyyy.”
Service Desk: “Oh, hi! I’m sorry, was something forgotten?”
Me: “I was wondering if I could talk with whoever worked on my car real quick? There’s an issue.”
Fortunately, said fellow IS available, and he comes out.
Mechanic: “What’s the issue, sir?”
Me: “Well, did you take the car for a test drive at all, even around the parking lot?”
Mechanic: “Of course, why?”
Me: “When it’s idling, it’s fine, but the second I put my foot on the gas at all, there’s a horrible rattling or grinding sound.”
The mechanic gives me a look like he doesn’t believe me and is just humoring me as we head to the car. I hop in, turn the car on, and rev the engine, and there’s the noise. His eyes go huge. We pop open the hood and, at his request, I rev it a few more times.
Mechanic: “Oh, God. Turn it off! I found it!”
Me: *Doing so* “What happened?!”
About three seconds later, he closes my hood, hand held up with something shiny in it.
Mechanic: “Someone who was in charge of putting the covers back on left the magnetic head of the torque wrench on a nut.”
Me: “Man, I’m glad I didn’t have my music up yet so I could hear that! If that had fallen off in the middle of the road, I’d have had a heart attack.”
Mechanic: “You should be good now. If anything else makes a weird noise, let us know.”
I thanked him and drove home, still with the radio off. Thankfully, no more noises — yet!
