Non-transferable warranties?

I’m sure the practice counts on a certain percentage of original owners selling prior to the end of the warranty. So the effective warranty period to them is something less than the “face value”. It’s a way to entice the original purchase without actually having the risk. The amount they have factored into the price therefore breaks even at some point less than the warranty. 
I’m in the position of having purchased a sub that is only a couple of months old but didn’t work out for the original owners’ room/system. It seems to have an issue with wireless transmission. As the original owner claims it worked fine for them, I’m now stuck with paying for the repair of what is most likely a manufacturing defect. This would have been more tolerable had I received a steep discount, but since the item was mint, and practically brand new, and no longer available, I paid up.

I had hoped the manufacturer might make a goodwill exception, as I like their product ow and had been looking to add another of their models in a swarm arrangement. Rethinking that now.

Manufacturers are not in the business of selling used goods... so why would they provide warranty for anyone other than the original owner?  If you choose to buy used, to save money, then you need to weigh the pros against the unlikely chance you will ever need any warranty work and need to pay out of pocket.  Simple

If I buy a car with a 100,000 mile/four year warranty and I sell the car after two years with 20,000 miles on it. That car is still under warranty.

There may be exceptions, but I’m not aware of any vehicle manufacturer that offers a transferable warranty on a new car. It would still be obligated to fulfill NHTSA recall orders, but that’s it.

There are manufacturer CPO programs that include a factory-backed warranty, but that’s different. The cost of the warranty is built into the sale price of the vehicle. The same vehicle, sold on the open market without the CPO designation, will cost less every time.

Most won't.  Some do.

No manufacturer of new automobiles, SUVS, trucks or other motor vehicles will extend new warrantees to those who purchase used, preowned, or otherwise previously registered and titled vehicles with the exception of a dealer "demo" or on a factory certified used vehicle but that is not a new warrantee that is a warrantee on a used car with often extended mileage as a consequence and result.
