I'm kind of in a similar situation - I dropped my car off for service after hours, and after hearing about the car being held due to backorder part on this notice I went over to grab some things from my car after they looked at it and moved it. I've got scratches covering my hood now that weren't there.Had my harness recall done and didnt realize the dealer scratched the hell out of my wheels. I should have done a complete walk around the car. I didnt notice until a couple of days later and I didnt drive the car because of rain. How does one scratch a customer wheel if it didnt needed to be taken off?? The dealer contacted me via email and was more worried about the negative survey I gave them lol. I got the wheels fix but rule of thumb always check your car after a dealers visit!
Not sure how to prove the scratches weren't there when I dropped it off (after hours), so we'll see how liability works out on this one. Also, no idea how long they'll have my car as I'm like the 7th car or so they have held for this recall.
