2005 Mazda MAZDA3 Problems

What owners report

Owners of the 2005 Mazda3 most often report the airbag warning light coming on or staying on, frequently after adjusting a seat or going over a bump, and many note that their vehicle was not covered by the related airbag campaigns. Power steering that cuts out intermittently is another common theme, along with air conditioning components that stop working and electrical glitches. Most complaints in the sample were filed between roughly 40,000 and 130,000 miles.

   Air bags

   Airbag warning light stays on

   • 19 complaints (20%)
   • median 77,000 mi at 9.5 yrs old (18 state mileage)
   • 6 mention a crash, fire or injury
   • filed 2007–2017

   Owners describe the red airbag warning light illuminating and often staying on permanently, in many cases after the driver or passenger seat was reclined or adjusted, or after driving over a bump. Some say the passenger airbag indicator switches on and off on its own. Dealers in several complaints said the vehicle was not covered by the airbag recall and offered diagnosis at the owner's cost, while others could not find a cause. Reported across a wide mileage range, from about 10,000 to 190,000 miles, with many between 60,000 and 130,000 miles.

   What to check: Turn the key to the on position and confirm the airbag light comes on and then goes out, and try moving both front seats through their full range to see whether the light triggers. Ask whether any airbag recall or sensor work was done, and have the stored airbag codes read before buying.

   2 excerpts from owner complaints in NHTSA records

   “The red airbag sign on the dashboard, at first would come on and off sporadically, but now it's on everytime I operate the vehicle, indicating that the airbags will either not deploy or deploy incorrectly. I've discussed this issue with many other Mazda 3 owners and it is a well known and prevalent issue. It is not related to any event, other than normal driving and operation.”

   NHTSA complaint #10851805, filed 2016-03, 130,000 miles

   “I drove over a bump and the passenger airbag light came on, and also the airbag light on the dash light up as well. Both lights turned off within a week, then for the past three months just the passenger airbag light has been switching on and off. This is an extreme safety issue, and the light has returned back on again. I fear if I was involved in an accident the airbag will not deploy.”

   Steering

   Power steering cuts out intermittently

   • 11 complaints (11%)
   • median 78,000 mi at 8.1 yrs old (11 state mileage)
   • 3 mention a crash, fire or injury
   • filed 2008–2017

   Complaints describe the steering suddenly becoming very heavy, sometimes with the power steering warning light on, and in several cases it returned to normal after switching the car off and restarting. Some owners report the wheel locking during a turn or at highway speed, and a few say other electrics such as the radio and dash lights flickered at the same moment. Repairs mentioned include a new power steering pump, replacement fluid and lines, or an independent shop advising the system needed replacement. Mostly reported between about 27,000 and 130,000 miles, with several cases around 50,000 to 100,000 miles.

   What to check: During a test drive, check that the wheel turns smoothly at parking speed and listen for whine or stiffness; ask whether the power steering pump, fluid, or lines have been replaced, and whether the assist warning light has ever come on.

I was traveling at approximately 65 miles per hour on the highway and the power steering light on the dash illuminated and then the steering wheel locked ,making it almost impossible to steer and have control of the vehicle..another instance , I was in the middle of making a turn when the steering wheel locked, this time the entire vehicle shut down forcing me to quickly try to restart the engine.”

Contacted Mazda and while they say they are aware of the problem, no recall has been proposed, therefore I was redirected to this site. Contacted Mazda over a year ago under the advice of 2 mechanics who insisted this incident should not happen to such a young car. …”

Buying note. A 2005 Mazda3 can be a reasonable cheap car, but budget for checking the airbag system and power steering carefully, since those are the symptoms owners report most. Confirm which recalls and service work were completed for the specific car, and get a pre-purchase inspection that covers brakes, A/C and the charging system.
