Wiring harness defects cause new Mazda recall

Mazda is recalling almost 8,000 vehicles due to wiring harness issues that could cause malfunctions in passenger frontal air bag system, turn signals, false instrument cluster warnings, and the engine starting system.

Mazda North American Operations filed a Part 574 notification with the National Highway Traffic Safety Administration (NHTSA) on July 1 for a safety defect on certain 2018 Mazda CX-9 crossovers, produced from Sept. 12, 2017, through Nov. 9, 2017.

Although there have been no reports of accidents or injuries, a weak retention force of the wiring harness connector terminals could result in an electrical communication disruption and cause passenger frontal air bags to fail to deploy in a crash, turn signal lights to become inoperable, or the engine unable to restart.

Mazda will notify owners, and dealers will repair the wiring harnesses. The recall is expected to begin on or before July 29.

This comes on the heels of an announcement by Mazda on June 28 that wheel lug nuts may loosen and fall off during normal driving on certain 2019 Mazda3 vehicles. That recall affects 25,000 vehicles.
