2018 Mazda CX-9

Mazda is recalling 8,274 large CX-9 utility vehicles over a wiring harness failure that could disable certain warning lights and/or crucial safety systems.

On certain 2018 Mazda CX-9s, a weak connection of the wiring harness connector terminals could lead to a disruption in electrical signals between various vehicle control modules, affecting front airbags, turn signals, ignition and/or false instrument cluster warnings.

The company is not aware of any incidents resulting from the defect, but is asking owners to return their vehicles to dealerships where the wiring harness connectors will be inspected and replaced as necessary with ones that have the proper retention force in the terminals.

The issue affects 7,854 in the US and federalized territories and 420 in Canada.

Customers can check on the status of their vehicles online at or by calling Mazda customer relations at (800) 263-4680.
