B20008
Due to a customer complaint of a cracked spring post, an internal quality inspection found that a galvanic barrier had not been installed between the galvanized Aeroskirt Spring Posts and the aluminum mounting plates on the bottom of the trailer. Over an extended period of time, this can lead to Galvanic Corrosion between the two mating surfaces.
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
