Mazda safety recall 1217F / NHTSA 17V-393 covers specified 2014-2016 Mazda3 vehicles built in Mexico and equipped with a hand-operated parking-brake lever. In cold conditions, water can enter through an inadequately sealed protective boot. The rear-caliper parking-brake actuator… Repairs typically run $0-$0. Severity: high.
The 2.5L Skyactiv-G with cylinder deactivation uses hydraulic valve clearance adjusters to drop and re-engage two cylinders. A PCM software fault in the control of those adjusters during the transition back from deactivated to full four-cylinder operation can let an intake valve… Repairs typically run $0-$0. Severity: high.
Incorrect programming in the Smart Brake Support (SBS) control software on early BP-generation Mazda3s causes the forward-sensing system to falsely detect an obstacle where none exists - commonly triggered by overhead signs, bridge shadows, guardrails or steam. The automatic emer… Repairs typically run $0-$0. Severity: high.
The FN4A-EL (Mazda's version of the Ford 4F27E) four-speed automatic used in the BK Mazda3 suffers sticking shift solenoids and worn valve-body bores. When a solenoid sticks or its driver circuit in the TCM fails, line pressure is no longer properly controlled: the car bangs into… Repairs typically run $400-$2,500. Severity: high.
The BK Mazda3 uses an electro-hydraulic power steering unit. Rust and debris from the steel pressure lines between the pump and the rack contaminate the pump's internal sensor/control circuitry, causing the electric pump to shut down and drop assist without warning. NHTSA opened… Repairs typically run $700-$1,500. Severity: high.
The in-tank low-pressure fuel pump supplied by Denso used an impeller molded with too low a density; it absorbs fuel, swells, cracks and deforms, then binds against the pump housing. Fuel delivery drops off, the engine runs lean, hesitates and can stall outright - sometimes at sp… Repairs typically run $0-$900. Severity: high.
The BK Mazda3's rear quarter panel lip has a folded seam with inadequate sealer and drainage. Salt-laden water and grit pack into the fold behind the plastic arch liner and the panel rusts from the inside out, so by the time bubbles appear in the paint above the rear wheel the me… Repairs typically run $400-$2,000. Severity: medium.
