If the steering effort feels heavy, this can be caused by a power steering fluid leak. Some models may have burrs on the return port of the power steering reservoir that create a gap between the hose and the port. Sanding the burrs off the port and replacing the power steering return hose is the repair for this concern.
The rear brakes can squeak because the rear brake pad may be contacting the brake rotor. A burr on the backing plate of the brake pad can prevent the pad from seating in the bracket properly causing the contact with the rotor. The backing plate and the pad support hardware can be deburred in the contact areas. Mazda has also released revised brake pads.
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.
A vibration felt at 55 mph may not be a tire problem. Mazda has revised motor mounts available which may help remedy this problem.
Damaged wiring to the seat belt pre-tensioner sensor may cause the Airbag Warning Light to illuminate.
A low speed stall when the throttle pedal is slightly pressed and released may mean the Engine Control Module (ECM) needs to be reflashed (updated).
