Mazda has started informing dealers in North America of a new safety campaign that potentially affects 187,798 units of the Mazda3, due to malfunctioning windshield wipers.
The NHTSA said that the wiper relay may have an improper design that might disrupt electrical power to motor, thus making the wipers inoperative and reducing the visibility while driving.
“The relay becomes defective when metal deposits form due to heat generated during normal operation, which causes eventual sticking of the relay contacts”, according to the feds’ description of the defect.
Mazda is unaware of any accidents, injuries or deaths related to this condition that affects 2016-2018 Mazda3s produced between July 20, 2015 and July 18, 2017.
As noted above, dealers have already been informed of the recall, whereas owners should hear from the automaker before June 3. The fix will see technicians replace the front body control module with a new one, said to “use an improved design”. All work will be carried out free of charge and those who have replaced the faulty parts on their own will be reimbursed.
The compact Mazda was previously involved in other safety campaigns conducted with the NHTSA that included other defects, such as possible fuel leaks and faulty parking brakes. The latter included the biggest number of cars, 227,814, and was carried out two years ago, with dealers taking care of the possible rollaway risk.
