2012 Mazda Mazda5

While accelerating from a complete stop at a traffic light on a multi-lane roadway, the vehicle suddenly lost all engine power without prior warning. The engine RPM dropped immediately to 0, causing the vehicle to stall in the middle of an active intersection and creating an immediate risk of a side-impact collision from oncoming traffic. All warning lights on the instrument cluster illuminated upon stalling. To clear the intersection safely, the vehicle was placed into Neutral and restarted. After shifting back into Drive and proceeding out of traffic, the vehicle repeatedly entered a fail-safe/limp mode every 30 to 120 seconds. During these episodes, the Automatic Transaxle (AT) light flashed, the engine shuddered severely, and the engine RPM fluctuated erratically, causing unpredictable acceleration and poor drivability. The sudden stalling in active traffic created a severe hazard to driver and occupant safety. The vehicle had not displayed a Check Engine Light or Transmission warning light prior to the complete stalling event.

The contact owned a 2012 Mazda Mazda5. The contact stated that while driving approximately 45 MPH, a deer wandered into the middle of the road, and the contact depressed the brake pedal and the wheels locked up, causing the tires to slide. The contact lost control of the vehicle and crashed into a ditch, spun around, and struck another object, causing the vehicle to land back into the ditch where it came to a stop. The air bags did not deploy upon impact. A bystander called 911, and the contact was taken to the hospital by ambulance. The contact bit his lips hard during the crash, which caused the bottom two front teeth to pierce through the bottom lip. The contact sustained a severe cut to the right leg, which led to excessive bleeding. The contact also sustained pain in the neck and lower back. The contact was given an X-ray and a CT scan to check for internal injuries, but none were found. The contact was released the same day. A Police report was filed. The vehicle was towed to an independent tow yard, where it remained. The vehicle was destroyed. Neither the dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 226,000.

Sentury Touring (Discount Tire) 205/55/R16. Both front tires have inner wear to the point of shredding in the same location on *both* front tires. Both tires went out at the same time and could have caused a serious accident. Discount tire stated it was an alignment issue. The alignment shop (30 minutes after new tires were installed after dual blowout) stated that my alignment was perfectly within spec and also stated there was no indication of tire rub on any portion of the vehicle.

This vehicle ejects a significant amount of fuel from its fuel filler port during every refueling. The volume of fuel and the distance the gasoline travels in a hazardous environment poses an avoidable risk that can result in a catastrophic event with potential fatalities. In addition, the cumulative quantity of fuel needlessly spilled negatively impacts the environment at a time of heightened environmental concerns. For these reasons, this known issue should be elevated from a simple technical service bulletin (#01-013-15-3048) to a safety recall before fatalities result from a known manufacturing defect.

During July of 2021 brake pedal went all the way down with no braking. Pumping the pedal restored braking. After the 3rd incident, had the master cylinder replaced on July 30, 2021 by certified mechanics. Brakes seemed fine, but on Aug 11, 2021 brake pedal went all the way down producing no braking on 3 occasions. Pumping the pedal restored braking. Took vehicle back to garage. Mechanics have not gotten it to fail. Possible new parts are bad? Could anti lock brake system cause this? Its been a really good car for 155,000 miles, but now I'm afraid to drive it.

The Mazda5 has a TSB on the issue, 01-013/15. What I am attempting to find out is why this isn't a recall. When the failure occurs, the fuelling of the vehicle doesn't shut off the nozzle. What happens is fuel comes spraying out of the opening, getting over the ground, the vehicle, and in most cases the person fueling the vehicle. My vehicle has been dong this almost since new. When I reported it early on, Mazda blamed the fuel pumps in my area. The next time I went in I presented the TSB but they still wanted me to pay for diagnostic procedures and even potentially for the repair. I think that's ridiculous. From what I understand, it's very common, common enough to have a TSB. Since it does cause environmental issues and safety issues by splashing gasoline on skin, clothing, and potentially could be ignited, well, why isn't this a recall? I do find the TSB to be carefully worded to specifically NOT say what actually happens, making it look like an inconvenience and not a safety issue. ****Video of what happens is available upon request.****

This SA supersedes the previously issued SA(s) listed below. The changes are noted in Red. SA-061/25 12/17/25 DESCRIPTION If you encounter any type of electrical concern (e.g, dead battery, engine no start, DTC(s) stored...), interview the customer before proceeding with normal MGSS diagnosis by asking if any aftermarket devices have been installed. Aftermarket devices may be the cause of the electrical concern. Below are a few examples of unusual electrical concerns caused by aftermarket devices. Examples: 1. Devices connected to the DLC-2 (battery discharge/DTC stored) 2. Devices plugged into the 12V outlet 3. GPS tracking device (engine no start/battery discharge) 4. Dash cam (DTC stored) 5. Non-certified USB cable (Apple Carplay™/ Android Auto™ will not connect) 6. Over-sized wheels/tires (incorrect GPS location) 7. DTC C0023:14 8. Decorative trim and/or cover on the START/STOP ENGINE button Example 1: Some electrical devices connected to the DLC-2 connector by insurance or mobile phone companies may cause: Battery discharge. The device may disrupt the CAN system battery saver mode. • IDS/MMDS will not communicate with the vehicle due to poor DLC-2 connection. The aftermarket device may cause DLC-2 female terminals to spread open.

This Service Alert supersedes the previously issued SA listed below: The changes are noted in Red.

Mazda recommends dealers follow the scheduled maintenance tables as cited in the vehicle-specific workshop manual or owner's manual. Services performed outside of Mazda's factory scheduled maintenance are not recommended. These services are unnecessary and create unneeded expenses for your customers. SCHEDULED MAINTENANCE Refer to the applicable Workshop Manual or Owner's Manual for vehicle -specific manufacturer scheduled maintenance. Workshop Manual - Refer to section 00-00 SCHEDULED MAINTENANCE. Owner's Manual - Refer to section 8 Maintenance and Care. b. Note: Please refer to the information below outlining the services not included in Mazda's Factory Scheduled Maintenance: IMPORTANT: Recommending fluid flushes when not necessary can lead to customer confusion and dissatisfaction. Fluid flushing for preventive maintenance purposes is strongly discouraged, unless otherwise specified in a published procedure (Owner’s Manual, Workshop Manual, Technical Service Bulletin, etc.).

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.

When replacing the SiriusXM satellite radio unit, a call must be made to inform SiriusXM of the existing Radio ID and the new/replacement SAT Radio ID as soon as possible to ensure the customer leaves the dealership with an active SAT radio.
