MAZDA Complaints

The Low Oil Level light/sensor came on before it was time to get an oil change (the recommended 4600 miles). This is super dangerous as it can cause major engine issues. I took it to the dealership and the dealership stated "they are having problems with these cars-they are burning too much oil so there is going to be a replacement valve once they have one made and you'll need to come back in to have it replaced -it will be a big job since it's part of the engine".

Car is consuming oil since new and requiring additional oil to be added before oil changes. There was a TSB created by Mazda a year ago (TSB # 01-012/21) however there is no fix. I am concerned with the potential for damage to other engine systems aside from the reported issue with the valve stem seals resulting in undrivability and premature engine problems due to oil leaking past the valve stem seals.

1000 miles before first ever oil change was needed (according to window sticker provided by Mazda) the low engine oil light came on. The oil was low and needed to be toped off and brought directly to dealer for oil change. The same thing happened again 1300 miles before second oil change was required. It became obvious that the brand new vehicle was burning oil for some reason. The dealership tried to tell us that it was because the car was a turbo. We weren’t buying it and told them we wanted it looked at. After brining it into the dealer they mentioned that Mazda had a bulletin for a valve seal fix that might help it stop burning oil. So they admitted that yes it was burning oil. After googling the bulletin I realized that our vehicle is having the same problems that many others with 2021 Mazdas (certain production period) are having. There is currently no recall however there is proof that these problems are damaging our vehicle, putting my wife and children at risk every time they get in the car and Mazda is doing nothing about it. There is also proof that these gases from the burnt oil are damaging other engine systems further increasing the likelihood of an engine failure. Down the road. Chances are this damage is already done, despite this valve seal repair.

After sitting in the heat of summer, cracks appeared on two of the corners of the LCD navigation screen making it very hard to see portions of the screen.

I have a 2018 Mazda CX-9 with about 66,000 miles. I noticed a coolant leak when my SUV sat in my driveway. It was there each night after driving the SUV. I took the vehicle to a Mazda dealer who stated that the coolant leak is from a cracked cylinder head. A cylinder head should not crack in 4 years and only 66,000 miles. This is a known Mazda issue for this year make and model.

Due to Mazda's known problem in the design of their engine at just over 80,000 miles the head and turbo of my engine have cracked. They have issued a service bulletin to their dealerships, which acknowledges this as a common problem. (Technical Service Bulletins (TSBs) are official communications between Mazda & its dealerships that describe processes for troubleshooting or fixing certain common problems.) Unfortunately, for most Mazda CX-9 owners this bulletin was issued after most have just passed their 60,000-mile warranty, thus allowing them to get away with designing an engine for a fairly expensive car that is only good for 80,000 miles. Mazda further acknowledges this as a problem as newer engines are no longer designed the same way to avoid the problem and any parts put on the engines that are failing are of the new design because the OEM parts will just fail again. Dealing with Mazda customer service is a joke, they are rude, refuse to answer questions and will not call you back with answers when they say they will.

I noticed a smell of antifreeze. After taking it back to dealership, I find out it has a cracked head. It has never ran hot.

On 1/22/21, I was driving for Lyft. I had a passenger in this car and I was giving her a ride home. I had a seizure towards the end of the ride, and was completely amnesiac to the crash that occurred. During my seizure, I was unable to check for clearance before I entered a highway and I crashed into another car. In the police report, it states that my air bags didn't go off. As a result, my head hit the windshield and I suffered a traumatic brain injury which was a brain hemorrhage. I had to spend a night in the hospital and I got 13 staples in my head. Now, over a year later I still get migraines and I can no longer drive due to symptoms from my complex PTSD. This has affected all aspects of my life, including my ability to find employment in my field of mental health. I have nine years of experience as a mental health professional, and most of the jobs in my field require a driver's license and car. This accident could have killed me, as well as the passenger in my car and the people in the car that I crashed into. I should have reported this accident earlier, but I was dealing with a deep depression and didn't even know I could report this until after I contacted a lawyer.

Vehicle displays low engine oil light about every 1,000 miles due to burning oil from faulty valve stem seals from factory assembly. Mazda has acknowledged the defect but plans to only refill engine oil. The defect could lead to possible injury due to low oil which could cause the engine to seize and cause sudden loss of power.

The cylinder head failed causing a massive leak of engine coolant. This occurred initially at highway speeds which caused potential danger to myself and others around me as the car was required to pull over immediately. The problem was confirmed by the dealer and is known to the manufacturer as indicated by TSBs. The part was inspected and replaced by a new, redesigned part at the owner's expense.
