Bought my 2021 dually used with 25000 miles check Air Suspension came on 5 miles after leaving the dealer, took it to a London Ontario Canada dealer for repair under warranty. No problem needs a gateway module, but we don't have any, don't know when they will be in stock. So.... Death in family requires that I drive to California to pick up a 4000 lb slide-in camper. Thinking that they might have the module by the time I do Christmas with the relatives. Well, off to California we go. Take dealer in Santa Rosa my truck. Everything is good, the dealer says module in stock! Leave the truck for repair ( estimated at 2 days).
Well that was over a month ago. Dealer and " Star case" have been working on it for over a month! Nothing seems to happen except "were working with Ram Star case, and we can't seem to find the issue......Good luck, were stuck here in California, been told to come and get your truck if you want, and get another dealer to fix it. Some service.
