2009 Mazda MAZDA3 Problems

What owners report

Owners of this model year most often describe sudden loss of power steering assist, usually at low speed or while idling, and often in hot weather; many say restarting the car restored steering. The other common theme is corroded tire-pressure (TPMS) valve stems that crack or snap and let a tire deflate, plus early tire wear on the original equipment tires. Reported mileages range from very low (a few thousand) to well over 100,000.

   Sudden loss of power steering assist

   • 29 complaints (25%)
   • median 25,500 mi at 1.8 yrs old (28 state mileage)
   • 3 mention a crash, fire or injury
   • filed 2009–2023

   Complaints describe the steering suddenly becoming very heavy, usually with the power steering warning light coming on, while turning at low speed, idling in traffic, or driving with the air conditioning on. Many owners say switching the car off and back on restored assist, while a few report it staying out until the car sat for a while. Some were told by dealers that the vehicle performed normally or that it was not covered by the power steering recall, and several reports involve pump, line or tube replacement. Most often reported between roughly 10,000 and 40,000 miles, with several complaints tied to hot weather or idling in traffic; a number of reports also come at higher mileage.

   What to check: Ask whether the electric power steering recall (10V374000) was performed and whether the pump, lines or tubes have been replaced; on a test drive, check that assist is present at idle with the A/C on and that no steering warning light appears.

   2 excerpts from owner complaints in NHTSA records

   “When sitting at a traffic light in my 2009 MAZDA3 4-door sedan, the power steering suddenly and unexpectedly stopped working. The warning light came on (a yellow steering wheel indicator with an exclamation point). I was able to drive home with much effort to make turns. Parked car in garage. 5 minutes later returned to check it again. Started car and power steering was functional again.”

   NHTSA complaint #10343534, filed 2010-07, 42,319 miles

   “On a few separate occasions (approximately three) during especially hot weather, the power steering has failed while driving my 2009 Mazda 3. One especially concerning instance occurred while driving on a highway in very heavy traffic. Each time I have pulled over, shut the car off, and turned it back on, following the instructions in the owner's manual. This has been successful for the most part. …”

   TPMS valve stems corrode and break

   • 25 complaints (22%)
   • median 50,000 mi at 4.1 yrs old (23 state mileage)
   • filed 2010–2016

   Owners describe aluminum tire-pressure sensor valve stems that corrode and then crack or snap off, sometimes while driving, letting the tire deflate quickly; several report repeated failures on different wheels. Some say the dealer or manufacturer attributed the corrosion to road salt or aftermarket valve caps and declined to cover it, while others had stems replaced with rubber ones. Complaints also mention nuts that crumble or fall off during routine pressure checks. Mostly reported between about 15,000 and 80,000 miles, often after several winters or in areas where road salt is used.

   What to check: Inspect each valve stem for corrosion or cracking and ask whether they have been replaced with rubber stems; watch for a tire pressure light and check pressures before and after a test drive.

   “I have had three oem valve stems rot out and completely fall into the tire causing a rapid deflation and risk of control loss of the vehicle. The first valve stem rotted out in 2012 and was replaced. I assumed it was an isolated incident (stuff happens). In the last 2 months the second and 3rd valve stem rotted out and have been replaced by belletire (2nd in july, 3rd today). Luckily I was driving on side roads when these occurred. It might have been much worse if I was on the freeway. …”

   NHTSA complaint #10536865, filed 2013-08, 40,000 miles

   “I constantly have issues with my tire pressure being low. I went to fill my tires up for the 3rd time in 4 months and as I put the compressor to the tire valve, the valve snapped off. All the air poured out of my tire. Luckily I wasn't driving at the time. I changed the tire to my donut and drove immediately to my tire center. They looked at the broken valve and told me it had corroded and that the whole tpm system would have to be replaced. He also went on to tell me that this is common. …”

   Tires

   Premature and uneven tire wear

   • 11 complaints (10%)
   • median 15,900 mi at 2.7 yrs old (9 state mileage, few)
   • filed 2009–2016

   Complaints describe the original equipment tires wearing out or going bald well before expected mileage, with several owners noting heavy wear on the inside edges and being told the factory alignment settings were the reason. Some report poor grip in light snow or wet conditions even when the tires still had tread. Owners say dealers often declined to cover the tires or suggested buying replacements. Typically reported under 20,000 miles, sometimes with rotations recorded at the dealer.

   2 related service bulletins

   What to check: Look closely at the inner edges of all four tires for uneven wear and ask for an alignment check and printout; confirm the age and remaining tread of the current tires.

   “Goodyear tire eagle rs tire in light snow / wet weather conditions, new 2009 Mazda 3 hatchback. Tires are totally inadequate in light snow conditions. I was unable to make a right turn while I attempted to slow down at 20mph. Car ABS was activated but I still skidded almost hitting another car as it was about to pull out in front of me. I am forced to have to replace these tires.”

   NHTSA complaint #10295096, filed 2009-12, 10,000 miles

   “Had my Mazda 3 oil changed today and found out that it needed new tires - at just under 15,600 miles. I had these tires rotated at just under 6,000 miles and just under 12,000 miles. The defect is due to the alignment set at the factory, that causes the rear tires to tilt in at the top to improve handling. I am having to pay for (4) new tires and paying an extra charge to get the alignment set correctly. I will never buy another Mazda product. …”

Buying note. Check the power steering recall status and whether the pump or lines have been replaced, and inspect the tire valve stems and inner tire edges closely, since these two areas account for most of the reports on this model year. A pre-purchase inspection that includes an alignment check and a scan for stored steering or airbag codes is worthwhile.
