Known Problems

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

If the engine cranks but won't start, the fault may be internal to the distributor. Diagnosis will show no spark and trouble codes for the crankshaft position sensor (CKP) or the camshaft position sensor (CMP). Our technicians recommend replacement of the complete distributor assembly if these conditions occur.

Mazda has issued Bulletin No. 01-010/10 for the above issue:

Some vehicles may experience the coolant level warning light comes on even though the correct amount of coolant is in the coolant reserve tank and radiator. The coolant level sensor float in the coolant reserve tank (A) is deteriorated and absorbs coolant. The float gets heavy, and sinks, causing the the coolant level warning light comes on. As a mass-production change, the design of the float has been modified.

Replace the necessary parts according to this VIN range.

• For VINs JM1FE****** 100000 to 157837 (built before July 1, 2005), replace the tank with sensor.

• For VINs JM1FE****** 157838 to 403405 (built on or after July 1, 2005), replace the tank only.

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 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.

The engine may overheat due to erratic engine cooling fan operation as a result of a faulty cooling fan control module. Replacement of the fan control module would be necessary to correct this condition. Our technicians tell us the Mazda may provide assistance with the cost of this repair.

Rattling noises from the front suspension while driving over rough roads can be caused by defective front sway bar bushings. Replacing the bushings with the updated design is a common repair.

A loose or corroded ground terminal on the driver's side of the cylinder head can cause a rough idle, misfires, and there may be trouble codes. Restore the ground to the cylinder head.

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.

Some models may have a problem where the Check Engine light illuminates indicating an improperly tightened fuel cap. Due to improperly manufactured threads on the fuel filler pipe, the filler pipe may need to be replaced.

If the engine cranks but does not start, it may be caused by a tripped inertia switch. Switch the key to "ON" and the fuel pump should be heard running for a second or two. Listen at the gas filler if necessary. The inertia switch is located on the firewall and can be tripped when the parking brake is set too hard and then released. The inertia switch should be reset, and will click when it is reset.

If the climate control's heat/cold knob is not adjusting to the desired temperature, a new climate control unit may be needed.

Damaged wiring to the seat belt pre-tensioner sensor may cause the Airbag Warning Light to illuminate.
