Statute of limitations?

What is the name of your state? Nevada
I purchased a vehicle from a well known dealership in Las Vegas about 3 weeks ago. Just the other day a caliper mounting bolt fell off of the vehicle causing about 367.00 in repairs that needed to be completed. After researching the matter, I found out that the bolt falling out was caused by a service technician, at the dealership where the vehicle was purchased, doing a brake job on the van and not installing the bolts all of the way, causing them to eventually wiggle loose and for one of them to even fall out, causing the caliper to fall down and rest on the rotor, if anybody is familiar with mechanics then you know that this situation can cause all sorts of wonderful noises, and that it is potentially a very dangerous situation. After fighting with the dealership and threatening to take legal action and contact the consumer protection department of our local news station, the General Manager of the dealership finally came to his senses and contacted me to let me know that he is willing to reimburse me for the repair, but that he cannot do it for a couple of weeks since he is going on vacation after today, and the individual authorized to write checks is not there today, so I was fine with that and told him I would get back with him on the 24th when he returns to complete the resolution, but then I got to thinking that maybe he is just trying to buy more time in an attempt to make me exhaust some kind of statute of limitation, does this make sense, is there a certain amount of time in which I have to take official legal action, otherwise I can't file a complaint any longer? If so, how long is that time period in Nevada?

Thank you.

Call him back and tell him you want that in writing before he leaves.

Then contact him once he is back.
