NHTSA Campaign #16V684000Reported: 22/09/2016

FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY

Summary: Mazda Motors North American Operations (Mazda) is recalling certain model year 2014-2016 Mazda3 vehicles manufactured January 4, 2014, to September 18, 2015. The fuel tank of the affected vehicles may have been improperly handled during manufacturing and, as a result, the welded attachment of the Inlet Check Valve (ICV) may fail and allow fuel to leak.

Safety Consequence: A fuel leak in the presence of an ignition source increases the risk of a fire.
Manufacturer Remedy: Mazda will notify owners, and depending on the tank lot number, dealers will inspect the ICV weld, replacing the fuel tank, as necessary, free of charge. The recall began November 1, 2016. Owners may contact Mazda customer service at 1-800-222-5500. Mazda's number for this recall is 0116I.
NHTSA Campaign #17V393000Reported: 22/06/2017

PARKING BRAKE

Summary: Mazda North American Operations (Mazda) is recalling certain 2014-2015 Mazda6 and 2014-2016 Mazda3 vehicles. Water could possibly enter the brake caliper causing the parking brake actuator shaft to corrode and possibly bind.

Safety Consequence: If the parking brake actuator shaft binds, the parking brake may not engage or disengage fully. If the parking brake does not engage properly, the vehicle may move unexpectedly if it is parked on a slope, increasing the risk of a crash.
Manufacturer Remedy: Mazda will notify owners, and dealers will check the parking brake actuator shafts, replacing any that are corroded, free of charge. Remedy parts are currently unavailable. Interim notices informing owners of the safety risk were mailed August 24, 2017. Owners will receive a second notice when remedy parts become available. Owners may contact Mazda customer service at 1-800-222-5500. Mazda's number for this recall is 1217F.
NHTSA Campaign #14V173000Reported: 03/04/2014

ELECTRICAL SYSTEM:ALTERNATOR/GENERATOR/REGULATOR

Summary: Mazda North America Operations (Mazda) is recalling certain model year 2014 Mazda3 vehicles manufactured June 12, 2013, through December 18, 2013, and model year 2014-2015 Mazda6 vehicles manufactured May 20, 2013, through December 4, 2013, and both equipped with a 2.5L engine and a regenerative engine braking system. When driving the affected vehicles in heavy rain or in deep puddles, the alternator belt may slip causing the Power Control module (PCM) to incorrectly assume failure of the charging system.

Safety Consequence: Once the PCM assumes that the charging system has failed, the vehicle will stop charging and could result in poor acceleration, loss of steering assist and windshield wiper operation, and a possible engine stall, increasing the risk of a crash.
Manufacturer Remedy: Mazda will notify owners, and dealers will reprogram the PCM with updated software, free of charge. The recall began on May 19, 2014. Owners may contact Mazda at 1-800-222-5500. Mazda's number for this recall is 7314D.
NHTSA Campaign #23V487000Reported: 14/07/2023

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA

Summary: Mazda North American Operations (Mazda) is recalling certain 2014-2018 Mazda3 and 2016-2021 CX-3 vehicles. The rearview camera image may not display properly by showing a flickering or distorted image.

Safety Consequence: A rearview camera that does not display properly can reduce the driver's rear view, increasing the risk of a crash or injury.
Manufacturer Remedy: Dealers will inspect and replace the rearview camera, as necessary. In addition, dealers will install a wiring harness fastening seal. All repairs will be performed free of charge. Interim notification letters, notifying owners of the safety risk, were mailed September 13, 2023. Final owner letters for affected models and model years in the states of CT, MA, MD, NJ, NY, PA and VA were mailed August 14, 2024. The remaining owner notification letters will be mailed at a future date, anticipated on or before May 1, 2025. Owners may contact Mazda customer service at 1-800-222-5500, Option 6.
