2007 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.

The contact owns a 2007 Mazda Mazda3. The contact stated that while driving 5 MPH and making a turn, the steering wheel was difficult to turn to the left or the right. The check engine warning light was illuminated and flashing. The contact stated that the steering then seized. While checking the NHTSA.gov website, the contact associated the failure to NHTSA Campaign Number: 10V374000 (Steering). The vehicle was taken to the local dealer, who confirmed there was no recall coverage on the VIN related to the failure. The vehicle was not diagnosed or repaired. The manufacturer was contacted and opened a case, and confirmed there was no recall coverage for the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 195,081.

Intermittently spanning several months, there is a sudden loss of power steering as the vehicle is in motion. Warning lights light up on the vehicle as power steering and power brakes are disengaged. Even though I provided a video of power steering loss, where a slight turn of the steering wheel engages this failure, where the dash board lights flash as power steering fails, the dealership will not fix anything they can’t duplicate in their shop. I guess they don’t believe their lying eyes, and don’t accept the video as proof of anything. It is doing exactly what it was recalled for back in September 15, 2010. Recall #10V374000. Mazda Corporate has been notified. Case # 00342901. There are known fixes for this problem. Mazda has done these repairs on hundreds of thousands of times. Dealership told me they will do nothing unless they can duplicate the problem. In reality it might take a month or more for this to show up at some unpredictable time and place. I have a potentially dangerous scenario awaiting me. Driving this vehicle in it’s present condition is recipe for a crash. This was a problem that Mazda addressed and fixed in the past. Being that it was done hundreds of thousands of times, I’m fairly certain that none of those fixes were predicated by mechanics having to see those issues in their shops before they did the repairs.

My daughter and I were on the way to O'Reilly when we turned at a short curve going under 20 miles and the steering wheel got loose and the brakes wouldn't stop us. The car just kept swerving all over the road and we ended up in a ditch the day after my husband purchased the car.

Power steering failure causing rust on car components. When turning my steering wheel to the left or right there is a noise the car makes and it jumps gear shifts making it very unsafe to drive this car. Also there is an electrical power issue with the car. I just bought a new battery for the car but there still seems to be a shortage And I have to power jump the car every time I tune the car off and have to start the the car up. This is very unsafe for me as the driver and unsafe for those around my when driving because of the locking steering wheel.

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.
