2009 Mazda Mazda3

The subject vehicles have electro-hydraulic power assist steering (EHPAS).The complaint counts shown above alleged a loss of power steering assist in the subject vehicles.Usually, but not always, the loss is accompanied by the simultaneous lighting of an indicator light on the dash.The complaints include 14 alleged crashes involving 6 injuries.On Mazda3 and Mazda5 vehicles manufactured from April 2, 2007 through November 30, 2008, rust may have formed inside the EPAS high-pressure pipe during manufacture due to improper processing.If the rust is present it may damage the power steering pump bearings leading to an increased load on the electric motor; this results in an elevated operating temperature for the EPAS system.To prevent excessive overheating of the system, which could potentially cause permanent damage, afailsafe mode which de-powers the electric pump is implemented.This causes a loss of power assist making it more difficult to steer the vehicle, especially at lower vehicle speeds.Once the failsafe is implemented the EPAS system will remain disabled until the ignition is turned off.However EPAS will be re-enabled if the operating temperature is reduced (i.e., within an acceptable range) on a subsequent drive cycle.On August 8, 2010 Mazda submitted a Part 573 defect information report initiating Safety Recall 10V-374 to remedy the subject vehicles.The report, which contains additional details on the remedy repair, is available at http://www-odi.nhtsa.dot.gov/recalls/.ODI notes that the affected population shown in that report includes approximately 8,000 vehicles Mazda repaired prior to initiating the recall.

When driving and trying to negotiate a turn, or sometimes when going straight, the power assist steering simply fails (stops assisting the steering). I have to "muscle" the car off the roadway and either restart the engine or stop the car (off the road) straighten the steering wheel, restart the car, and the power assist is restored. This has happened five times in the last 9 months. So far there have been no accidents. The date velow is the most recent date of this failure.

For the past 9-10 months and on occasions, when I step on the brake pedal to either slow down or stop from a normal cruise speed, the engine rpm quickly jumps up to 2000 - 2500 rpm. I have to quickly brake harder and *place the auto transmission selector in NEUTRAL to fully stop the car from lunging forward*. The date below is the most recent date.

The fuel pump lock ring on my 2009 Mazda Mazdaspeed3 has failed which is causing two engine codes: P0442 and P0455. In addition there is a strong smell of gasoline fumes around the rear of the car after driving and parking. The fuel pump lock ring is a plastic threaded ring which secures and seals the fuel pump and fuel level sender to the fuel tank. Mazda has released a safety recall 5121I for MY2009-2011 RX-8 and MY2006-2007 Mazdaspeed6 vehicles. Mazda states: "On certain subject RX-8 and Mazdaspeed6 vehicles, improper installation of the fuel pump mounting rings may lead to cracking of the rings, causing fuel leakage. In addition, on certain RX-8 vehicles, the fuel pump mounting rings may deteriorate due to heat exposure from the engine and exhaust pipe due to insufficient heat resistance at the top side of the fuel tank. This may also lead to cracking of the rings, causing fuel leakage. Fuel leakage may result in increased risk of fire in the presence of an ignition source near the vehicle." The faulty part number for the RX-8 matches that of the Mazdaspeed3. That is Mazda part number: BN8F-42-167 I believe the failure of this part and recall should extend to affected Mazda 3 vehicles, and any other models with the same part. I have opened a case with Mazda Corporate. Case number: 14466166445 I have uploaded a video of the smoke test performed by a local shop indicating the leak is coming from the ring: https://photos.app.goo.gl/6t6KeeaDPLgGzvvaA I have also attached a screenshot of the video, unfortunately the image quality provided by the mechanic is very poor.

THIS SEEMS TO HAPPEN AS I'M SLOWING DOWN, AS YOU WOULD TO MAKE A TURN ONTO A STREET OR DRIVEWAY. I TURN ON MY BLINKER, THEN THE MOMENT I PRESS THE BRAKE, ALL OF THE POWER IN THE CAR DIES, AND COMES RIGHT BACK ON. I THINK OF IT AS A QUICK RESET IT SEEMS. HOWEVER, WHEN THIS HAPPENS, THE POWER STEERING DOES NOT WORK, AND I'M LEFT FINISHING MY TURN WITHOUT POWER STEERING. THE POWER STEERING IS THE ONLY THING THAT DOES NOT "RESET" WHEN THE POWER FAILS. THE POWER STEERING MAY TAKE 3-6 SECONDS BEFORE IT COMES BACK. AND IT ALWAYS COMES BACK ON, BUT NOT UNTIL AFTER I'M THROUGH MY TURN. IT TYPICALLY SEEMS TO HAPPEN WHEN MY BLINKER, AND BRAKE IS APPLIED, ALMOST LIKE THE POWER OF THOSE LIGHTS SHUTS EVERYTHING OFF. BUT THIS ALL HAPPENS AT RANDOM. I HAVE A PART TIME JOB ON THE WKNDS DELIVERING FOOD. IT STARTED OUT JUST MAYBE HAPPENING ONCE A MONTH, AND THAT WAS 3-4 MONTHS AGO. NOW IT'S EVERYTIME I GO OUT, IT'S LIKELY TO HAPPEN, BUT WHEN, IT'S IMPOSSILBE TO TELL BECAUSE I CAN TRY EVERYTHING TO MAKE IT HAPPEN THAT NORMALLY MIGHT SEEM TO BE THE CAUSE AND THEN NOTHING. I'VE READ A LOT OF FORUMS RECENTLY THAT HAVE A LOT OF PEOPLE WITH EITHER EXACT PROBLEMS OR VERY SIMILAR. I DON'T LIVE IN A BIG CITY BUT FOR PEOPLE THAT ARE DRIVING THIS CAR IN A BIG CITY THATS BUSY, THIS IS VERY DANGEROUS, AND NOT ONLY THAT PEOPLE ARE GONNA END UP GETTING IN SMALL WRECKS FOR SOMETHING THAT COULD BE TAKEN CARE OF WITH A RECALL. PLEASE DO SOMETHING. I'M UNABLE TO WORK MY WKND JOB WITH THIS ISSUE SO IT'S COSTING ME 3 DAYS OF WORK UNTIL I GET IT FIXED. THANK YOU.

A musty/mildew type odor may come from the vents when the air conditioning (A/C) system is operating. It is most noticeable when the A/C is first turned ON. This odor is the result of mold growth in the A/C evaporator/cooling unit which is caused by condensation, dust, and pollen within the cooling unit. This condition is usually worse during high humidity conditions. “Mazda Air Cooling Coil Coating” is available to encapsulate the mold to reduce odors. If the product is properly applied, it can effectively reduce the musty/mildew odor for up to three years. NOTE: See parts information for Mazda Air Cooling Coil Coating and Kit part numbers.

Some vehicles may experience exterior trim heat damage such (melted, separating, etc.) when parked near a glass building or Low-E windows. This may be caused by the sun's reflection. If a structure's windows create enough of a curve, the concave glass can focus the sun's rays onto a small area and acting like magnifiying glass direct the sunbeams into a hot pinpoint of light. This magnifcation of the sun's rays can cause damage to vehicle trim (see examples). Additional information and exemplar images regarding this phenomenon can be found by performing a google search.
