NHTSA Complaint #11504661 — 2022 RAM 3500

We were traveling westbound on the interstate I-10 towards Los Angeles California on Nov 13/22 near Cabazon CA in my 2022 Ram 3500, SRW, 6.7 HO with the Aisin transmission. It was rush hour stop-and-go traffic. I was traveling at a speed of approximately 35mph when a large bang came from under the vehicle. There was an immediate and complete power loss and we had to coast to the shoulder of the road and try to avoid being struck by traffic. Once on the shoulder, I had got out and checked under the vehicle. There was nothing that I could see that was wrong. There was a check engine light that went on. Using a jobber OB2 scanner, codes P0731 (Gear 1 incorrect ratio) and P0732 (Gear 2 incorrect ratio) were present. The truck was towed to the Redlands CDJR dealer for service with only 6700 miles on the odometer. It turned out to require a complete new Aisin transmission. The repair took a month to complete and looks to have been caused by a defective snap ring as per service bulletin 21-002-23 (K1 clutch drum snap ring and K1 input shaft drum sub assembly) although the Redlands CDJR dealer or FCA will not confirm. The bulletin states the affected vehicles are the 2022-23 Ram 3500 pickup, 3500 cab and chassis, and 4500/5500 Cab Chassis trucks. Due to the immediate power loss, with zero warning, we were just able to get to the shoulder of the road and could have easily caused a massive pile up and possible deaths due to the failure. FCA refuses to inspect or confirm that the new transmission (68498560AB) installed in my truck addresses the 21-002-23 service bulletin and said I would need to pay out of pocket for the inspection to occur at a dealer. There are numerous documented cases of newly installed transmissions failing shortly after being "repaired". I believe it would be in the publics best interest that FCA/RAM issue a recall on the effected vehicles as these vehicles are typically used for emergency, commercial and towing application's.
