What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2012 Freightliner M2, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

SWAY BAR VERTICAL LINK BUSHINGS ARE PULVERIZED COMPLETELY GONE WITHIN 1500 MILES AFTER REPLACEMENT CAUSING AN UNSAFE TOP HEAVY ROLL OF THE MOTORHOME REDUCING STEERING CONTROL OF THE VEHICLE. I'VE HAD FREIGHTLINER SAN DIEGO REPLACE THESE BUSHING, I'VE REPLACED THEM TWICE, AND HAD A SUSPENSION SHOP REPLACE THEM ONCE. EVERY OTHER SENECA OWNER BUILT ON THE FREIGHTLINER M2 CHASSIS EXPERIENCES THE SAME ISSUE. FREIGHTLINER RECOGNIZES THERE IS AN ISSUE THROUGH A TECHNICAL SERVICE BULLETIN TSB-32-47, BUT HAS NOT ISSUED A RECALL ADDRESSING THIS SERIOUS ROLL AFFECTING CONTROL OF THE VEHICLE. CHECK THE RV FORUMS ANYONE WITH ONE OF THESE CHASSIS ARE EXPERIENCING THE SAME VEHICLE CONTROL OVER THE INADEQUACY OF THE CONNECTION POINTS OF THE SWAY BAR. I FIRST NOTICED THE BUSHING WERE GONE AFTER OUR FIRST TRIP IN THE MOTORHOME ATTEMPTING TO REPAIR AN OBVIOUSLY POORLY DESIGNED SUSPENSION COMPONENT.
