Mazda is recalling certain 2018-2020 vehicles because the impeller inside the low-pressure fuel pump may crack and deform, potentially causing the fuel pump to fail.
In March 2019 Mazda received the first field report of an engine stall due to an inoperative fuel pump. A study of the pump showed that cracking on the impeller surface made the impeller more likely to deform. Further investigation found that solvent used during the manufacturing process and low-density impellers may be factors causing impeller cracking. During the test, the surface of the impeller cracked as the solvent dried over time. It was confirmed that fuel pumps produced with impellers of lower density exposed to production drying solvent for longer periods of time could experience the impeller cracking at a level that could lead to excessive fuel absorption, and could cause impeller deformation.

Fuel pump failure may result in engine no start and/or vehicle stall while driving at low speed and, in rare instances, a vehicle stall could occur while driving at higher speeds, increasing the risk of a crash. Drivers may notice this defect by a check engine light, and/or rough engine operation.
Mazda will be contacting owners of affected vehicles with instructions to return to their dealers to have the fuel pump replaced. Mazda’s number for this recall is 5321K and the NHTSA campaign number is 21V-875.
Mazda will be contacting owners of certain 2019-2020 Mazda 3 cars because of a programming error affecting the forward collision avoidance system.
According to the defect report, incorrect programming of the smart braking system (SBS) control software may cause the vehicle to falsely detect an obstacle and apply the brakes to avoid a collision. If the SBS is unexpectedly activated while driving, the risk of a rear end collision from the following vehicle is possible. Drivers will be warned when the defect is occurring through an audible alarm and a warning message displayed on the dash board.
Dealers will correct the problem by updating the SBS software.
