These vehicles are equipped with a tire pressure monitoring system designed to warn the driver if the pressure in one or more tires becomes to low. In the affected vehicles, if all four tire were to gradually loose pressure at the same rate the tire pressure monitor system (TPMS) may not alert the driver of the drop in pressure. If the vehicle is operated with the tires at the incorrect pressure sudden tire failure could result, increasing the risk of a crash. Dealers will update the TPMS software to correct this concern.
The electronics for the hybrid system have their own unique cooling needs. The coolant pump for this system can fail resulting in overheating of the hybrid electronics. As a result the powertrian may shut down causing the vehicle to stall, increasing the risk of a crash. Dealers will replace the Motor Electronics Coolant (MEC) Pump with an improved "brushless" pump to correct this concern.
In a crash that deploys the passenger front air bag, the inflator of the air bag can rupture, causing metal debris to strike vehicle occupants. Dealers will replace the front passenger air bag inflator free of charge to correct the concern.
This limited regional recall is for vehicles currently registered or first sold in Florida, Puerto Rico, Hawaii and the U.S. Virgin Islands, and equipped with Takata-brand air bag inflators. Upon deployment the driver and/or passenger airbag inflator could rupture, increasing the risk of personal injury. Mazda dealers will replace the affected airbag inflator modules to correct this concern.
Due to a software issue that affects operation of the torque sensor, the electric power steering may stop functioning. This would make it difficult to steer the vehicle. Dealers will reprogram the power steering control module and instrument cluster module free of charge to resolve the concern. Dealers will also replace affected electric steering components as necessary upon inspection free of charge.
In some cold weather states, the lower control arm of the vehicle front suspension may corrode excessively and fracture. Dealers will install a newly designed reinforcement cross-brace free of charge to resolve the problem.
The fuel tank may allow too much fuel to be filled, which can cause evaporative emissions system contamination and a possible fuel leak. Dealers will inspect and add an adapter to the shut off valve in the fuel tank, along with inspecting the charcoal canister in the evaporative emissions system for fuel contamination free of charge to resolve the concern.
The powertrain control module (PCM) may incorrectly assume that the charging system has failed, in the event that water causes slippage of the alternator belt. This can cause needed vehicle accessories and functions such as power steering or windshield wiper operation to fail. Dealers will reprogram the PCM with updated software free of charge to resolve the concern.
Spider webs inside the vent hose of the evaporative canister can cause excessive fuel tank pressure and cause the fuel tank to crack and leak fuel. Dealers will inspect and replace damaged fuel tanks and check valves, inspect and clean the canister vent line and reprogram the powertrain control module free of charge to resolve the concern.
Three screws attach each door latch, over time these screws can loosen. If the latch screws loosen excessively the door latch may not engage correctly, the door could open unexpectedly while the vehicle is in motion, increasing the risk personal injury or an accident. Dealers will add a thread locking compound and re-torque the latch mounting bolts to correct this concern.
