I'll give you an example of one of the worst denials I have encountered with a warranty company that I can remember, and I'm just stating this as an example of how the companies can nit-pick and get you on the fine print so always read the exemptions on the agreement if you get one and take it as literal as you can imagine.
Customer had a used 2015 Durango he bought from a Dodge dealer. Within 6mo he is having A/C problems in a persistent leak and the vehicle has 1234 refrigerant so really expensive to fill. First time we tested we found a confirmed leak in the upper left of the condenser, which if I remember correctly, was a common problem on those MY Durango. Customer came back I think 2 times after that and we are fixing what we believe is the problem and then refilling the refrigerant under warranty each time. Finally it comes back again and after a week of having the car we finally confirm that there is a tiny leak near the back right rear of the car in the auxiliary A/C lines which book time claims 9hrs but once fully evaluated we settled at 13hrs since the rear crossmember and trans have to be dropped to get the lines out, and 9hrs just wasn't going to cover that. So all of that time for a $120 A/C line? The customer has an extended warranty and so I run it through them and they deny the claim stating their exemptions which I read over and it says they don't cover any lines or hoses. I felt bad for the customer with this ordeal because the customer was probably the nicest guy I ever dealt with and totally understanding of the situation so I argued with them about it. I explained that an AC line is not like other lines and hoses in a vehicle, and basically that a large portion of the system is comprised of AC lines so if you state you cover A/C systems then you should cover the lines, and I personally believe the A/C lines should be covered because they are supposed to be durable and handle corrosion and road debris, etc but they often don't. I knew it was a lost cause after they denied the claim but I had to try for an exemption, and at the customer's request I even tried to get the dealer to cover it under goodwill which they ran up the chain and I got a denial from them of course also. So in the end the customer ended up throwing down over $2500 to have the line replaced.
That car took so long to diagnose and find that problem that we had to finally just evac the system and fill it with 134 refrigerant with the dye to find the leak because the dye in the 1234 was not showing up well enough and at about $500 per fill my boss was tired of losing money on it. I think we had the car for a total of 2 weeks trying to find that leak and then had it for another week doing the repair.
