The defect
Mazda North American Operations (Mazda) is recalling certain 2014-2015 Mazda CX-9 vehicles sold, or ever registered in the states of Alabama, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, South Carolina, Texas, Puerto Rico, American Samoa, Guam, the Northern Mariana Islands (Saipan), and the U.S. Virgin Islands or "Zone A." Additionally, unless covered in "Zone A," Mazda is recalling certain 2011-2013 Mazda6, 2011-2012 CX-7, and 2011-2015 CX-9 sold, or ever registered in the states of Arizona, Arkansas, Delaware, Illinois, Indiana, Kansas, Kentucky, Maryland, Missouri, Nebraska, Nevada, New Jersey, New Mexico, North Carolina, Ohio, Oklahoma, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia, or "Zone B." Additionally, unless covered in Zone A or Zone B, Mazda is recalling certain 2010-2013 Mazda6, 2010-2012 CX-7, and 2010-2015 CX-9 vehicles ever registered in the states of Alaska, Colorado, Connecticut, Idaho, Iowa, Maine, Massachusetts, Michigan, Minnesota, Montana, New Hampshire, New York, North Dakota, Oregon, Rhode Island, South Dakota, Utah, Vermont, Washington, Wisconsin, and Wyoming or "Zone C." These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the passenger frontal air bag, these inflators may explode due to propellant degradation occurring after long-term exposure to absolute humidity and temperature cycling.
The risk
An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
The remedy
Mazda will notify owners, and dealers will replace the front passenger air bag inflator with an alternate inflator, free of charge. The recall began November 9, 2018. Owners may contact Mazda customer service at 1-800-222-5500, Option 4. Mazda's number for this recall is 1317F.

STEERING

16V203000 · April 11, 2016

The defect
Mazda North American Operations (Mazda) is recalling certain model year 2016 CX-3 vehicles manufactured June 1, 2015, to December 2, 2015, 2013-2014 Mazda2 vehicles manufactured July 3, 2013, to August 8, 2014, 2014-2016 CX-5 vehicles manufactured January 19, 2013, to December 2, 2015, and 2013-2015 CX-9 vehicles manufactured December 6, 2012, to July 31, 2015. The lower mounting nuts and bolts that attach the front strut assembly to the steering knuckle may loosen, allowing the steering knuckle to separate.
The risk
If the steering knuckle separates from the strut assembly, it can cause a loss of steering control, increasing the risk of a crash.
The remedy
Mazda will notify owners, and dealers will inspect the lower mounting nuts and bolts that secure the front strut assembly to the steering knuckle. If the bolts are loose, they will be replaced and then correctly tightened, free of charge. The recall is expected to begin May 20, 2016. Owners may contact Mazda customer service at 1-800-222-5500. Mazda's number for this recall is 9316D.

ENGINE
My Mazda has been serviced regularly, in fact my next oil change isn't for 2,000 more miles. I was driving when I heard this weird noise. I looked at the dash and the oil light was flashing and the temperature was over heating. I could also feel the vehicle getting sluggish. I pulled over on the interstate. All the lights were on by this time. I popped the hood and there wasn't any coolant in the resivour anymore. I let the car cool down and I added some water as I was 1 mile from the exit where there was a gas station. I had to baby the car to the exit and shut it off whenever it got hot. The oil was full and seemed overfull even..... Mechanic is guessing the coolant leaked if the

ENGINE
We have a 2015 Mazda CX-9 Touring with All-Wheel Drive (AWD). The issue that has been happening is a flashing check engine light (CEL) indicator showing up in the gauge cluster. This issue originally started in October of 2023. I was on the highway doing at least 55 miles per hour (mph). Before the light actually came on, I had already felt the vehicle shaking, and also noticed the acceleration was sluggish. In the blink of an eye, the CEL came on and started flashing. After that point, the CEL stayed on. I was able to get to my destination safely. We took the vehicle to a shop, and told the mechanics the issue, but they could not re-create what happened. We stopped driving the vehicle as

ENGINE AND ENGINE COOLING

124,000 miles

The contact owns a 2015 Mazda CX9. The contact stated that while driving at approximately 55 MPH, the vehicle shut off. The contact stated that the engine was overheating. The contact restarted the vehicle, and the vehicle stalled again. The vehicle continued to coast into a parking lot. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the water pump, timing chain, cam phaser, timing chain tensioner, and an engine replacement were needed. The vehicle was not repaired. The manufacturer was not contacted. The approximate failure mileage was 124,000.

ENGINE
The issue is with the design of the Water Pump on this vehicle. From my understanding, this is a common issue with the 2015 Mazda CX-9. What happens is once the water pump starts to fail due to the design, the vehicle starts to stall randomly which poses a safety issue to my family when driving. The vehicle was inspected by a dealership in the area and was ultimately fixed. I was informed that the water pump has been redesigned by the manufacturer to prevent this issue from happening again.

ENGINE
My check engine light came on. Thought it was the oil needing to be changed. Oil was extra dark and muggy. Also notice antifreeze low. Fill up antifreeze and change oil. 2 wks later antifreeze back down low. Check engine still on. Got it diagnosed with auto scanner and says camshaft sensor. Went to autoshop, mechanic says it's not cramshaft sensor but water tank leak in engine which was picked up by camshaft sensor. I have yet to find out what else is wrong or if my engine needs to be replaced. For sure the water tank needs replacement. I read from others of their car over heating or completely stopped working. I fear this because I have 3 kids and on weekends I drive on the highway for

Where these numbers come from

A complaint is one owner's account and has not been verified by NHTSA or by us. A vehicle with more complaints is not necessarily worse: models that sold in larger numbers collect more of them. How this is counted.
