One problem related to front seat belt retractor has been reported for the 2001 Dodge Ram 2500. The most recently reported issues are listed below.
The drivers seat belt did not tighten up during an accident and I bounced off the steering wheel a couple of times. The seat belt had not tighten up after reaching for the radio controls or a drink, hung out the door when shutting it, but would always tighten up once janked on a couple of times. Never thought it would not work during an accident.
