Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

I purchased a 2014 Mazda CX-9 back in May of 2020 w/ roughly 60k on the dash. Literally 7 months later w/ about 72k on the dash, the day after Christmas I was driving to work (I worked in the next state over) on the highway my car just shut down. No warnings, no check engine lights NOTHING! It just completely shut off and would not turn on. Thankfully because of the holiday the highway was pretty empty and I was able to swing my car across the interstate so I wouldn’t get hit by oncoming traffic. After getting out and deciding to check my oil I noticed it looked milky. I had no idea what that meant so I had it towed to a Mazda dealership in the state I live in. It was going to cost me almost $8,000 to put in a new engine because the water pump that was placed inside of the engine failed, which in turn caused my engine to seize. The extended warranty I had on my vehicle was worthless so I ended up paying out of pocket. Thankfully Mazda worked with me and had me prove that I kept up maintenance on the truck so the price was chopped in half. This happened right at the beginning of Covid when the entire world was suffering financially. I still had to make my car payments on top of shelling out 4k on a truck I hadn’t even had for a year. This is a huge issue with a lot of people that own the same vehicle and is extremely dangerous! I could’ve killed someone or worse myself when my vehicle stalled out on the highway.

NHTSA ID 11597219 · filed Jun 27, 2024

The water pump failed causing water to mix with the oil and damage the head gasket. Estimates recommend replacing engine. The service engine light came on and we took it to our trusted mechanic right away. Got the estimates from two mechanics for this repair and then towed the car to Mazda dealer who confirmed the problem. We wrote to Mazda's corporate office and was told they would not fix it. My car has 68,000 miles and was regularly serviced. It is currently sitting dead in my garage. We bought this car in 2015 brand new from the Mazda dealer in Monroeville, PA. This is outrageous! I spoke with someone else who also owns a Mazda and the same thing happened to his car. From articles I have read and attached, this problem is occurring in many Mazdas. What needs to be in place for Mazda to take responsibility and fix this problem by recalling the affected vehicles?

Brakes stopped working while we were on vacation. Made the drive down fine, but the next day went to drive the car, pressed the brakes and the car did not come to a complete stop. Also made a funny noise when we tried to press on the brakes. My husband practically had to stand up and push all the way down to get car to stop. Luckily we were not in a congested or confined place. Ended up replacing the brake booster. Three weeks later my acceleration stopped working intermittently. I go to press the gas and the car doesn’t go. The dealership is saying it’s the brake signal.

NHTSA ID 11538158 · filed Aug 12, 2023

Breaks became very hard to press and I was having trouble stopping the car. I could not drive it to the Mazda dealer who was too far. I took a chance and drove a few miles to local break shop. They replaced the master cylinder and the break booster. Parts and labor were $1083.87

- Water pump failed causing coolant to mix with oil. This repair cost was around $3,900. - Luckily this failure happened on our community road and was able to pull into our driveway. Mechanic stated that if this happened on the highway or regular road, this could have caused a major incident and possibly a blown motor. - No, but complaints of similar issues have been reported via my online research. - Just by the mechanic I had my vehicle towed to. - There was no indication of an issue until the water pump failed.

TAKATA RECALL MY COMPLAINT IS THAT I HAVE RECEIVED SEVERAL NOTICES REFERENCING THE TAKATA AIRBAG PROBLEM. MAZDA HAS STILL NOT INITIATED A RECALL. I HAVE SUPPLIED MY EMAIL ADDRESS TO THE TKRESTUCTURING.COM/PPIC IN REFERENCE TO THE CHAPTER 11 CASE NO. 17-11375 (BLS). MY COMPLAINT SPECIFICALLY IS AGAINST MAZDA AND WHY THEY ARE DRAGGING THEIR FEET IN INITIATING RECALLS FOR THE AFFECTED AIRBAGS. WE HAVE NOT HAD AN ISSUE YET, BUT DO FEAR WHAT COULD HAPPEN IF A VEHICLE CRASH WOULD DEPLOY THE AIRBAGS. INJURIES AND EVEN DEATH COULD HAPPEN. MAZDA NEEDS TO BEGIN ISSUANCE OF THE RECALL NOTICES ASAP. I AM USING TODAY'S DATE BELOW SINCE A DATE IS REQUIRED TO CONTINUE.
