Mazda Mazda3 Problems

Check Engine Light/Trouble Code Due to Stuck Open Thermostat

Some vehicles may experience Check Engine Light illumination with a trouble code indicating the thermostat is stuck open. The thermostat will need to be replaced with a modified one and there is a software update for the Powertrain Control Module (PCM).

Vibration Felt at 55 mph

A vibration felt at 55 mph may not be a tire problem. Mazda has revised motor mounts available which may help remedy this problem.

Rattle From Rear Suspension Due to Loose Stabilizer Bar Links

A Loose rear stabilizer bar link can cause a rattling noise from the rear suspension while driving on rough roads. Our technicians tell us if the rear stabilizer bar and links are not found to be loose, there are updated sway bar bushings available which should correct this problem.

Mazda Mazda3 Recalls

Lift Gate Falls Unexpectedly

The rear lift gate support struts may corrode and fail, and the lift gate may fall from the open position, or not stay open as expected. Dealers will replace the lift gate supports free of charge to resolve the concern.

Fuel Leaks, Engine Stalls

The fuel tank shut off valve may allow fuel to enter into the fuel tank emission system unintentionally. This may result in a fuel leak to the ground and engine stalling. Dealers will inspect the vehicle's fuel shut off valve and replace it as necessary, as well as replace any further affected fuel tank emissions system components free of charge to correct the concern.

Charging System May Fail

The powertrain control module (PCM) may incorrectly assume that the charging system has failed, in the event that water causes slippage of the alternator belt. This can cause needed vehicle accessories and functions such as power steering or windshield wiper operation to fail. Dealers will reprogram the PCM with updated software free of charge to resolve the concern.

Mazda Mazda3 Reviews

Loved this little car. Only complaints were that air conditioning was weak and the low profile tires, while good looking, make the ride a tad rough. I know it's a sporty little wagon but you definitely felt it on poor California roads. Oh and the rear view mirror causes a huge blindspot at four-way stops! Especially for this long-torso guy!
Nice interior materials, good ride, and good safety rating. Averaging 32 MPG on a commute that's about 50-60% city/traffic driving. Biggest downside in my opinion is that the A-frame creates a bad forward-driving blind spot that can hide a whole car when turning/pulling out at intersections.
Sold on Mazda. The 3rd Mazda3i I owned very good cars it's very safe drive gets great performance has lots of upgrades loving the value of this car.
