I've been pondering purchasing a new Bronco. The major issue keeping me from pulling the trigger is the 10-20k dealer markup over msrp their selling these trucks for. Yeah, they have some teething issues, but Ford has stepped up working with their supplier base to remedy issues. I read they sent workers and engineering into the Webasto plant, the manufacturer of the hard top to help sort out the defects. I can't imagine the stress the folks that reserved a new Bronco, and still haven't taken ownership of their vehicle after 600 days are dealing with. Hopefully some of these supply chain issues work themselves out and they can enjoy their Broncos in short order.
Luckily it sounds like the valve issue was a small batch of parts in effected engines, and the failure rates been relatively low.
