Recalls and investigations

2 recalls on the electrical system cover the 2014 model year. A recall on the same system isn't always the same failure, so read the defect text.

14V-173Apr 3, 2014
Electrical System:Alternator/Generator/Regulator

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.

Risk and remedy
Risk: 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.
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.
14V-170Apr 3, 2014
Fuel System, Gasoline:Storage:Tank Assembly

Mazda North America Operations (Mazda) is recalling certain model year 2014 Mazda6 vehicles manufactured October 25, 2012, through May 9, 2013. In the affected vehicles, it is possible to fill the fuel tank beyond its rated capacity.

Risk and remedy
Risk: If the tank is overfilled, gas may flow into the charcoal canister (an evaporative emissions component) and possibly leak from the canister's external vent, increasing the risk of a fire.
Remedy: Mazda will notify owners and dealers will inspect and add an adapter to the shut off valve in the fuel tank and also inspect the charcoal canister for the presence of gasoline, replacing it as necessary, 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 7414D.

Should you keep driving it?

This page can't tell you that. 0 of 28 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
