MAZDA Complaints

The low engine oil light is coming on every 3500 miles. When checking oil level it indeed is low and requires a quart of oil. There is an active TSB out as this is a known issue but no recall issued yet.

While driving at freeway speed in Oregon, with 85 degrees ambient temperature and A/C inside set to 74 degrees, our CX-9 sunroof exploded outward. The sound was close to a very loud pop, and not the sound of rock/debris impact. At the time of explosion, there were no vehicles nearby and no overpasses from which an object could have dropped. The vehicle had been washed the day before and there was no visible damage to the sunroof. At the time of explosion, the sunroof and interior cover were closed. Upon stopping the vehicle (within less than one mile) inspection showed that nearly no glass fell downward, and approximately 50% of the total sunroof area had blown upward and out of the vehicle. The remainder of the shattered glass was still contained within the frame, with the edges visibly curved upward as though the glass had been pulled away from the car. There were three people in the vehicle at the time (driver, front seat passenger, and middle row passenger behind the driver). The two passengers were asleep and woke abruptly thinking we had been hit by something, as the explosive bang was followed by the sound of air rushing past the hole. There was no sound of glass rattling in the area over the sunroof cover, which seems to indicate glass had not broken inward and then blew out before stopping. I (driver) kept the cover closed and promptly pulled off the freeway to assess damage. I was unable to visit a dealer for warranty assessment due to vacation travel. A phone call to my local dealer did indicate it should be covered under warranty but it has not been inspected, this has not yet been confirmed. I rarely open the sunroof cover and have only opened the sunroof itself 3-4 times since purchase two years prior (2020). I did open the sunroof to give my son fresh air on curvy roads approximately one hour prior. No injuries, but if the cover had been opened we may have had glass falling into the cabin. No other visible or audible warnings occurred.

Fuel pump. The mechanics at the Mazda dealership brushed me off when I brought up the open recall on my vehicle. However, according to them it is a "preliminary recall," the mechanic said it wasn't an "open recall." This is my first vehicle and I stupidly put my trust into the mechanic and believed his words. I am not well-versed in vehicles but after extensive research, asking a friend, and referring to a VPC agent who deals with recalls on vehicles; it turns out there is no such thing as a preliminary recall outside of Mazda's definition. I told the mechanic it was an open recall and that I need to ship the vehicle to Hawaii and the shipping company can refuse service if there is an open recall. The mechanic still brushed me off and talked to me as if I was dumb because I couldn't understand what he was saying. He continued to say they don't have the parts regardless and said "no one does." I didn't press the issue because I assumed they knew better than I. It seems as if Mazda is refusing to work on, look at, or even hear about the fuel pump recall.

Excessive oil consumption. Recently purchased new vehicle with 0 miles. Oil low level warning light on at 3500 miles. Manually checked oil level. Added one quart. Online research indicates problem is created by faulty valve guide seals which allows oil into the engine combustion chamber and exhaust. Vehicle will be taken to dealership for inspection.

Pulled up to gas pump, put parking brake on (manual transmission), got out of car and heard a beeping noise from inside. The car then began to drift backwards into traffic. Have DashCam video that can share.

I purchased this vehicle with 19K miles on July 31, 2020. I noticed on April 12, 2022, that there was a knocking noise coming from the left front suspension after leaving a Mazda dealership for an oil change. I called Mazda service and was told they only did an oil change. I have put 4 brand new tires and have replaced the front/back brakes, rotors and still hear noise going over uneven pavement. I brought it to my own mechanic twice and he hears the noise but informed me that he cannot order any suspension parts at all for Mazda CX9. He said Mazda are forcing Mazda customers to go to a Mazda dealership. He called 5 different places to purchase strut. suspension and was told they had none. He also said Mazda has a special wrench to work with having to do with suspension and he cannot get one. My mechanic had my vehicle for 3 days and said it's definitely a suspension issue. My Mazda only has 35K miles. In 2 years, I have only driven 16K (8K) per year. There is no way a suspension should go after only 35K miles. I am not off roading or abusing the vehicle. Can't NHSTA assist with this issue? This is very serious. I am afraid to drive this Mazda now.

Our head gasket is needing to be replaced and sounds like this is an apparent Mazda problem how wide spread it is. The cost is over $5,000 for this single repair, possibly over $6,000 if head is cracked. I only have a parts list showing $1,700 in parts. Service manager said about 18 hours at $189hr totalling $3,402.

On 04/21/22, I took my car to the dealer after noticing antifreeze on our garage floor and a burning smell. NO check engine lights had illuminated. They proceeded to tell me that there was a coolant leak from head/block and cavity leak (something about channel pressure). They also stated this was a casting flaw during manufacturing of the engine. They told me I needed a whole new engine for $8,479.97! Mazda corporate refused to replace the engine at their cost because I had 64,575 miles on it and it was out of powertrain warranty. I called them and asked to speak to a supervisor and never heard from them. I called on 4/26, 4/27, 4/28, 5/4, 5/5 (5 times), 6/9, & 6/20. I finally gave up agreed to pay $7,479.97 (the dealer gave me $1,000 off). I received the car back on 05/20 and it would not start later that day. They towed it back to Mazda and they replaced the crankshaft sensor that was damaged upon install of the new engine. I received it back again on 05/31 and later in the day, the check engine light came on and the automatic braking system engaged while I was driving (thankfully only 40 mph). I managed to pull over in a turn lane before the engine died. I was so thankful I did not make it onto the interstate I was about to enter! Mazda came and picked me up and later got my car. They could not figure out why it was dying and finally got it to recreate it. They replaced another engine sensor and then drove it a lot to make sure it was truly fixed. I finally received my vehicle back on 07/07. I am afraid to take my car out of town and it makes me nervous it will die and automatically start braking again. They KNOW this is a manufacturer issue and they refuse to take responsibility. I am so disappointed in them. This is a huge safety issue. I am also lucky I didn't blow a head gasket before I took it into the shop the first time.

My Mazda has a feature called SBS (Smart Brake Support). It is touted as a safety feature, as it will brake the car when it approaches an object without driver braking. It can be disabled by the driver via the navigation panel; however, it automatically engages again upon engine start up. On a few occasions, when approaching a vehicle, I have braked and release, upon seeing the vehicle ahead begin to move. On such occasions, my Mazda's SBS activated, screeching my car to a near stop, scaring me and the vehicle behind me nearly rear-ended me. This action scared me, which affects my ability to control the situation and conduct appropriate action. I have contacted Mazda to ask for a permanent deactivation of this dangerous feature. They have been unable/unwilling to assist. They have concern that if a different driver should drive my vehicle, it would be problematic. I explained that this is my vehicle and I fear their SBS feature will cause me to be rear-ended and seriously injured. I have requested that the Mazda Customer Service rep submit a safety complaint on this issue. An Internet search finds that there are other customers with the same safety concern on Mazda's SBS feature. It is time that this be addressed.

I purchased my car on February 5, 2022. After two months and 3000 miles later, I started receiving a notification that reads “Airbag Malfunction. Have the vehicle inspected.” I took the car to the dealer, and after 6 hours, they determined that the airbag was not receiving enough power, which triggered the warning. They replaced the part, and now two months later, I have received the same notification. This problem is persistent, and I have seen in forums that many are having to deal with this issue. Mazda needs to recall the cars to replace the parts with ones that will not cause this type of inconvenience. After all, airbags are a huge part of safety.
