UNDERHOOD FIRES

What NHTSA is examining

In documents provided during ea04-027, honda identified a mechanism which causes the rubber seal (gasket) of the original equipment (oe) oil filter to adhere to the engine block of the subject vehicles.if an adhered seal remains when the oe filter is removed and a new filter is installed, a double gasket condition results.a subsequent rupture of the extraneous seal can result in oil contacting nearby exhaust system surfaces and a fire may occur.throughout its discussions with odi, honda has maintained that it is the servicing technician?s responsibility to inspect for and remove the seal prior to installing a new filter.odi?s analysis found that seal adhesion, in conjunction with technician error and exhaust component location, resulted in a high rate of subject vehicle oil filter fires compared to earlier models and peers.vehicles that have not had the oe filter disturbed are not at risk.service replacement filter seals, which are manufactured by a different supplier, do not exhibit the seal adhesion condition.therefore, if the initial oil change is done properly, the elevated fire risk is eliminated for the remainder of the vehicle?s life.based on average mileage accumulation and oil service interval, odi estimates that more than two thirds of the subject vehicles have received their initial oil change and are no longer at an elevated risk.honda changed the design of the filter seal to prevent the adhesion condition and introduced the new seal at both cr-v assembly plants…
