Shortly after buying 2014 superduty f350 crew cab diesel used truck in june 2017, airbag lights started coming on and off. was told they airbags not activate if we were in accident. dealer who sold it to us did not offer any help, dealer near us could not locate problem since airbag lights went off and on could not locate issue, tried replacing driver side module, no luck. months later dealer traced problem by removing steering wheel and airbag, and replacing the "sliding contact". we had to drive truck 5 months without the safety of aibags.
