Owners have filed 686 complaints with NHTSA about the 2010 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 3 recall campaigns for the 2010 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 2011 Mazda2 and 2010-2011 Mazda3 and Mazdaspeed3 vehicles equipped with a manual seat lifter. In the affected vehicles, the seat height adjustment lifter links may break or detach from the seat frame and the seat angle may incline causing the driver to not be able to maintain an appropriate driving position.
Risk: If the driver cannot maintain an appropriate driving position, there is an increased risk of a crash.
Remedy: Mazda will notify owners, and dealers will inspect the seat lifter links and install a reinforcement bracket to the lifter links, or replace the entire seat adjuster unit, free of charge. The recall began April 7, 2017. Owners may contact Mazda customer service at 1-800-222-5500. Mazda's number for this recall is 0917B.
Mazda North American Operations (Mazda) is recalling certain model year 2010-2013 Mazda3 and Mazdaspeed3 vehicles manufactured November 18, 2008, to June 8, 2013, 2012-2015 Mazda5 vehicles manufactured October 26, 2010, to June 22, 2015, 2016 CX-3 vehicles manufactured June 1, 2015, to December 26, 2015, and 2013-2016 CX-5 vehicles manufactured December 15, 2011, to December 26, 2015. On the affected vehicles, the lift gate support struts may corrode, possibly causing the struts to break and/or the lift gate to drop unexpectedly.
Risk: If the lift gate falls unexpectedly, it may hit the user, increasing their risk of injury.
Remedy: Mazda dealers will replace the both lift gate supports, free of charge, however parts are not currently available. The recall began April 2017. Owners may contact Mazda customer service at 1-800-222-5500. Mazda's number for this recall is 9916H.
MAZDA IS RECALLING 25,400 MY 2010 MAZDA3 VEHICLES. A CLEARANCE BETWEEN THE ENGINE HARNESS AND THE HOUSING OF STARTER MOTOR MAY BE INSUFFICIENT. DUE TO THIS, THE COVERING OF THE HARNESS MAY BE DAMAGED THROUGH VIBRATION DURING OPERATION POSSIBLY CAUSING A SHORT-CIRCUIT BETWEEN CERTAIN HARNESS WIRES AND THE STARTER HOUSING. A SHORT-CIRCUIT CAN RESULT IN ENGINE CONTROL MALFUNCTION AND/OR POOR SHIFT QUALITY.
Risk: THE MAIN FUSE MAY BLOW OUT CAUSING THE ENGINE TO STALL AND INABILITY OF RESTART, INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL HAVE THE ENGINE HARNESS INSPECT AND ADD A PROTECTOR CLIP ON THE AFFECTED SECTION OF THE HARNESS. IF NECESSARY, THE HARNESS WILL BE REPAIRED. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE RECALL IS EXPECTED TO BEGIN ON MAY 6, 2009. OWNERS MAY CONTACT MAZDA AT 1-800-222-5500.

NHTSA defect investigations
Opening an investigation isn't a finding of a defect. Outcomes are as NHTSA's summary states them. A recall is shown as an investigation's outcome only where NHTSA's summary names it; other recalls NHTSA's file lists with it are marked as listed, not caused.
