Massey Ferguson DEF Sensor Investigation

Migliaccio & Rathod LLP is investigating reports that certain Massey Ferguson 8S tractors equipped with Tier 4 emissions systems experience premature DEF quality sensor failures that can force reduced-power operation or equipment shutdown.

What Consumers Report

Owners report:

  • Unexpected DEF quality sensor failures.
  • Emissions-system fault warnings.
  • Reduced engine power during field operations.
  • Repeated dealer visits for emissions repairs.
  • Expensive replacement sensors.
  • Lost productivity during planting and harvest.
  • Sensor failures recurring after replacement.

Why Consumers Should Be Concerned

DEF quality sensors are intended to operate throughout the useful life of agricultural equipment. Massey Ferguson consumers allege that these sensors fail prematurely, leaving otherwise functional tractors unable to operate normally and causing significant financial losses through repair costs and downtime.

Potential Claims May Include

  • Product defect
  • Design defect
  • Breach of express warranty
  • Breach of implied warranty
  • Magnuson-Moss Warranty Act violations
  • Consumer protection violations
  • Failure to disclose known defects
