Braun Ambulances (Braun) is recalling certain 2019 and 2021 Crestline CCL150 Type III E-Series and 2019-2020 Crestline CCL150 Type I F-Series and CCL150 Type III G-Series ambulances. Two of the eight fastening points of the seat belt system installed in the ambulance patient compartment side-facing CPR seating position on the street-side of the vehicle may be defective. Two of the threaded inserts used for the rearward retractor and shoulder belt D-ring are installed too close to a mounting flange resulting in improper crimping of the threaded insert.
