2003 Mazda Mazda6 Problems

Engine -- Verified

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.

Engine -- Verified

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.

Electrical & Lights -- Verified

Mazda recalled certain models due a problem that could cause the fog light bulb to fall out of the fog light assembly. The repair involved inspecting the fog lights and installing a spring clip to prevent the light bulb from falling out.

2003 Mazda Mazda6 Recalls (Recent)

Body, Interior & Misc., April 11, 2013

RepairPal Expert Overview:

Airbags use a chemical reaction contained in an inflator module to create the pressure necessary to inflate the bags when deployment is required. These vehicles are being recalled because the front passenger airbag inflator may produce excessive internal pressure when deployed and as a result, the inflator module could rupture, causing metal fragments to strike vehicle occupants. Dealers will inspect and replace any defective passenger front airbag inflator module found.

Electrical & Lights, July 14, 2003

RepairPal Expert Overview:

The heat generated by a fog light bulb can cause the socket holder to be pushed rearward in the light casing. This, in combination with the normal vibration during vehicle operation, can cause the bulb holder to separate from the light casing. Should this occur, the bulb socket and harness can drop inside the bumper and possibly result in the bumper being burned by the hot bulb. Dealers will install a spring to prevent the socket holder from separating from the lamp case. The Mazda recall number is 1103F.

2003 Mazda Mazda6 Reviews

The worst car I have ever had and heard of. I have had to put 17K to keep it on the road and payed 18K when I bought it.

Have had my Mazda 6 since 2003 new. Absolutely love this car! Been a wonderful machine and still kicking. It now has 239,000 plus miles on it. Have had to change the starter once, a few brake changes and have replaced the tires twice. Can't really complain about the car as its been doing its job and well worth the money. Will not give up this car for nothing.

Just had the actuator replaced and there is a valve ping when accelerate till certain speed, let of and speed up it pings..What is this.timing chain? Should they have known this when fixed acuator?

After my car hit past around 80k miles I've had a lot more problems. I have had to change the brakes about 2 times since I bought the car+ the rotors. A couple recalls at the beginning because it was a new model, the transmission program had to be updated, fan was alwasy on. I had one engine problem where after it rained the engine would start sputtering while driving and it would go away after it dried out (was a ignition coil problem). I recently have had the air intake valve needed replacing from the check engine light going on and the car just stopping. I've had to replace the headlights a few times from burn out and the tires seem to bald faster than usual and they are expensive to replace.

I still like this car but I seem to be having a lot more engine problems now and it's beginning to get annoying. I would expect it to at least last decent until 100k miles and I might buy another mazda.

btw don't go to a deal for a engine code check, my local mechanic reads it for free not $100.

Bought this car new for my daughter in January 2003. Currently has 67,000 miles. Other than a half a dozen recalls (new model) the car has been very reliable.
Pluses: The V-6 engine gets about 20 MPG in town and as much as 29 on trips. Handling, ride and acceleration are superb. Interior has held up well and is easy to clean. Car is very versatile with 60/40 folding rear seat and large trunk. Very good safety features for a 2003 model.
Minuses: Have had to replace engine battery every three years and brake pads every 30K; primarily routine maintenance is all that has been required. Abrupt shifting between 1st and 2nd gear develop around 50K--required transmission software update to fix. Oil pan leak was repaired during 60,000-mile service. Center console LEDs have been erratic (also affected by the cold).
Overall, a very good car with many more years of service planned.
