What can fail
Water can enter the brake caliper and cause the parking brake actuator shaft to corrode and bind, potentially affecting parking brake function.
This page covers 7 recalls, 137 owner complaints and NHTSA crash-test ratings for the 2014 Mazda Mazda6.
5/5 Overall
NHTSA 5-Star Safety Rating
Electrical system complaints dominate what 2014 Mazda6 owners report, with the powertrain and engine rounding out the most-discussed areas. On the electrical side, a recurring theme involves the transmission's park position sensor failing to register that the car is actually in park, owners describe being unable to shut off the engine or lock the vehicle until they cycle through the process multiple times, sometimes spending ten minutes or more getting the car to recognize the park position. Powertrain complaints overlap with this, as some owners report the transmission getting stuck in a single gear and the shifter not behaving predictably. Engine reports are less concentrated but include a pattern of EVAP system fault codes triggered during fuel fill-ups, with owners noting the check engine light cycling on and off depending on how full they fill the tank.

By System
The 2014 Mazda6 has 7 recalls, the most serious being two separate fire and power-loss risks: a fuel tank that can overfill and leak gas near ignition sources, and a charging system fault on 2.5L models with regenerative braking that can cut power steering, wiper operation, and cause an engine stall.
The fuel tank venting system on certain vehicles allows the tank to accept more fuel than it should, which can push gasoline into the charcoal canister and out through its vent, where it can ignite. The regenerative braking system issue is a separate concern: a software fault causes the powertrain computer to incorrectly conclude the charging system has failed, after which the vehicle stops charging its battery and can lose power assist for steering, windshield wipers, and eventually the engine itself. On the brake side, water can get past the parking brake caliper boot and corrode the actuator shaft, leaving the parking brake either unable to fully engage or dragging while the vehicle is moving. There is also a tire pressure monitoring issue where a gradual, even pressure drop across all four tires may go undetected by the system, leaving the driver unaware of underinflated tires that can fail suddenly.

What can fail
The protective boot on the rear brake caliper may fail, allowing the parking brake actuator shaft to corrode and become stuck. This reduces parking brake holding force or causes dragging while driving.
What the fix does
Dealers will inspect the rear caliper assemblies and repair or replace them as needed.
Summarized — see the official notice for exact wording, dates, and contacts.

What can fail
When all four tires lose pressure simultaneously, the tire pressure warning system may fail to alert the driver of the pressure loss.
What the fix does
Dealers will update the tire pressure monitoring system software at no cost to the owner.

What can fail
A fault in the regenerative braking system can cause the charging system to malfunction, triggering a warning light and error message. If you keep driving, the engine may stall and you could lose power.
What the fix does
The dealer will reprogram your powertrain control module to fix the charging system fault.
