I'm not here to defend Kia, but the reality is that they are likely having to put their resources into the recall for wire harnesses, which is the reason we don't have 2023 hitch options right now.
I know their recall was for the 4-pin, but the reality is that Kia probably uses the same manufacturing source for their wire harnesses on all Tellurides. The supplier is capacitized on their manufacturing lines for the annual volume contracted by Kia for the Telluride. This then gets reduced down to supplier daily capacity. So, for simple math, let's use capacity at 120,000 annually and 240 production days per year. That means the supplier can produce or are contractually obligated to produce 500 wire harnesses per daily. 36,000 Tellurides were recalled, which means they have 72 production days committed to the recall. Potentially worse news? If the same supplier was making the wire harness for
Palisade and Kia, that means their daily capacity would be 1,000, however there were 245,000
Palisade recalled. That means 245 production days to meet the need. Now reality is that the supplier likely has more time available than what they are contractually obligated. Since the supplier may potentially liable and want to save face with Kia/Hyundai, they are going to do everything in their power to get these wire harnesses built.
Since their marketing is slanted to pump up the towing capacity, and this was likely developed long before the recall, they are likely not in a position where a lawyer would have any luck with a class action lawsuit against Kia.
Just because a parts dealer said they can't order a hitch has nothing to do with if Kia designed a hitch. They likely have not released the part number into their customer care, aftermarket sales parts database. They are trying to save face on the recall at the moment.
The information above is based on my experience in automotive manufacturing and not based in any information I know first hand with Kia/Hyundai or this situation. All of that being said, it wouldn't take much for Kia to just identify this information to customers, but Kia seems to enjoy keeping their dealer network and customers in the dark with the 2023 Telluride.
