NHTSA Engineering Analysis EA10002

Ford and Mazda recalled model year (MY) 2001 through 2004 Ford Escape (07V-156) and Mazda Tribute (07V-157) vehicles due to non-crash fires or non-fire thermal events originating in the engine compartment at or near the ABS control module.Approximately 545,700 vehicles were subject to the initial safety recalls and approximately 424,700 vehicles were serviced under those campaigns. The campaigns addressed potentially damaged, missing or misplaced seals in the ABS control module wiring harness electrical connector that could allow brake fluid to enter the connector, possibly resulting in corrosion, short-circuit, melting, smoke and/or fire.Since the recall, the agency is aware of 260 subject vehicles that have reportedly experienced non-crash fires or non-fire thermal events originating at or near the ABS control module in vehicles some time after being serviced under the campaign. The post-recall repair incident rates for MY 2001 and 2002 subject vehicles are 90.9 and 126.7 (normalized per 100,000 vehicles serviced under the recall campaigns), respectively.These rates are much higher than the post-recall repair incident rate for MY 2003 and 2004 subject vehicles, which are 5.0 and 3.7 per 100K, respectively.Similarly, the post-recall repair key-off fire incident rates in the MY 2001 and 2002 subject vehicles is 54.3 per 100K, compared to 0.5 per 100K for the MY 2003 and 2004 subject vehicles.The agency is aware of 12 key-off fire incidents, all involving MY 2001 and 2002 subject vehicles, where the vehicle was parked inside a structure when the fire started.In five of those incidents, the fire spread from the vehicle to the structure itself.Ford has identified the brake master cylinder reservoir cap in certain MY 2001 and 2002 subject vehicles as a potential source for brake fluid leaks that could affect ABS module connector integrity.The reservoir caps used on the MY 2003 and 2004 subject vehicles are reportedly an improved design from those used on the earlier mod
