2003 Mazda Protege Problems

Engine Cranks and Doesn't Start

An electrically shorted air flow sensor can cause a crank-no start condition. Diagnosis may show that ignition spark is normal, and there are no trouble codes stored.

Squealing In Timing Cover Area When Cold

The timing belt tensioner pulley may make a squealing noise from the timing cover area on cold startup. An updated tensioner with a thicker mounting bracket to eliminate vibration may be needed to solve the problem.

Idles Rough, Misfires, and Possible Check Engine Light

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.

2003 Mazda Protege Reviews

Been a great little car with No big repairs yet at 110000 miles
Great car... bought it with 14,000 miles on it, now have 190,000 miles. Used it for daily two hour commute (each way) for five years. Did have to replace alternator twice. Gave it to my son to use at college and got it back from him a year later. Fun to drive. Only con, a bit noisy on the road.
This is my wife's daily driver to haul the kids around. We bought it new in 2003 and now has 85000 miles on it. No major problems. One recall for the manifold that was done. Great on gas!
