NHTSA Complaint #11672062 — 2018 CHRYSLER PACIFICA

Van was working fine one day and the next, before I even started it, when I pressed the brake pedal to start the van, there was a buzzing noise from the braking system and pedal went almost to the floor. Once I started the vehicle, the noise stopped and the pedal travel returned to normal. However at the same time, the warning light / message for several of the systems came up (ABS, traction control, collision detection, parking sensors, etc) along with several messages (ParkSense Unavailable, FCW Unavailable Service Required, Service Antilock Brake System, Service Electronic Stability System). Using an OBDII code reader displayed several "communication errors" (start with the letter "U"). I researched it on the Internet and it would appear that this is caused by a common failure of the "star connector" ("bus module" to connect various components in the van). I ordered a replacement part (which I haven't received yet) but not completely surprisingly, about 1 week after the issue occurred, today my vehicle was running properly with no more errors. I'm hoping NHTSA forces FCA to fix this issue under a recall. I've read of several other owners suffering the same issue and IMO, this is a security risk as ABS and traction contol (along with other systems) are disabled when this happens. In included pictures of the dash when it happened (note all the warning lights) and of the dash when if fixed itself (no warning light although MIL is still on (I haven't cleared it))
