NHTSA Complaint #11487542 — 2012 YAMAHA XTZ12

The ABS module on the Super Tenere is known to fail in such a way as to leave the rear brake inoperable (the brake pedal can be bottomed out without any resistance and without applying any pressure to the rear caliper). This happened on my 2012 Super Tenere, and has been discussed considerably among multiple other Super Tenere owners who have experienced the same failure. This is a significant safety risk, as any ABS module failure should fail in such a way as to leave both front and rear brake operable. It is believed amongst Super Tenere owners that the failure occurs largely due to the Unified Braking System (a subsystem contained within the ABS module which applies rear brake when the front brake is applied). It is believed that moisture penetrates the system through a vent hole, causes corrosion on moving internals, and damaged seals and corroded pistons allow air to be sucked into the system. Pictures of the corroded internals of a failed unit can be provided upon request.
