RepairPal has identified the most common problems for 31 Mazda models based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
Various electrical issues may develop related to the body control module (BCM). There have been reports of water damage to the BCM caused by clogged or damaged sunroof drains. It is recommend to periodically inspect the sun roof drain for debris and clean as necessary.
A loud ticking noise (hydraulic valve lifter noise) may be heard from the top of the engine, particularly when the engine is still cold. The noise may occur more frequently on higher mileage vehicles; Hydraulic valve lash adjusters may need to be replaced to correct this issue. Following the maintenance schedule for oil changes will also help prevent a recurrence of the noise.
If the engine is misfiring, it may be caused by a damaged wire(s) which connect the fuel injectors to the Powertrain Control Module (PCM). The damaged wire(s) can be repaired or the emission wire harness replaced. A misfire can result in a loss of engine performance and illumination of the Check Engine Light.
Premature automatic transmission failure is common. Diagnoses of the fault will be necessary to determine if repair or replacement is the proper repair.
The engine may develop a ticking noise from the front of the engine due to a worn timing chain. Our technicians tell us that replacing the timing chain and related component will generally correct this issue.
The cooling fan module can fail causing the fan to either run constantly, or not operate at all. If the fan runs continuously, the engine may not warm up properly, and if the fan does not run, the engine may overheat. Mazda has a voluntary recall on model years 2002-2003 to address this concern.

A vibration felt at 55 mph may not be a tire problem. Mazda has revised motor mounts available which may help remedy this problem.
Some models may have a problem with stalling under light acceleration. Updated software for the powertrain control module (PCM) is available which may help with this concern.
A lack of power may develop due to a failed turbocharger. Failed turbochargers will require replacement to restore engine power.
Excessive engine vibration or knocking noises heard while the engine is idling, being started or switched off are usually caused by a defective engine mount at the top right side of the engine. A redesigned engine mount is available to alleviate this problem.
