Didn't get that letter but last November i got a Safety Recall from the FCA US LLC regarding:
"loss of air bag and seat belt pretensioner deployment capability during a crash...."
"Wait for FCA US to contact you again by mail with a followup recall notice when remedy parts are available."
It goes on to say, there's no current solution.
Affects various Chrysler vehicles including 2010 to 2014 Compasses and Patriots.
Haven't heard anything since.
2014 Patriot Latitude 4X4 | 2000 Jeep XJ | 2016 Ford F150 XLT | 2005 Dodge Neon
