NHTSA's VIN data lists these trims for the 2015 Mazda3. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 130 complaints with NHTSA about the 2015 Mazda3. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 4 recall campaigns for the 2015 Mazda3 over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
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.
Risk: A rearview camera that does not display properly can reduce the driver's rear view, increasing the risk of a crash or injury.
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. Mazda's number for this recall is 6023G.
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.
Risk: 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.
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.
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.
Risk: A fuel leak in the presence of an ignition source increases the risk of a fire.
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.
Mazda North American Operations (Mazda) is recalling certain model year 2015-2016 Mazda3 vehicles manufactured May 21, 2015, to August 25, 2015. The affected vehicles are equipped with a fuel tank with a shut-off valve that can allow fuel to enter into the fuel tank emissions systems. If enough fuel enters the emission system it may leak out onto the ground or result in an engine stall.
Risk: A fuel leak in the presence of an ignition source increases the risk of a fire. An engine that stalls increases the risk of a crash.
Remedy: Mazda will notify owners, and dealers will inspect the vehicle's fuel shut-off valve. As needed, the fuel shut-off valve and the affected fuel tank emissions system components will be replaced, free of charge. The recall began on October 20, 2015. Owners are advised not to drive their vehicle until the repairs have been completed. Mazda will provide rental cars until that time. Owners may contact the Mazda Customer Experience Center at 1-800- 222-5500, option #6. Mazda's number for this recall is 8615J.
