ENGINE
the vehicles experience excessive oil consumption because the defective valve stem seals allow engine oil to leak into the combustion chambers. This concern usually occurs when the mileage reaches approximately 2,000 – 3,000 miles (5,000 - 7,500km) and may also occur again after replacing or topping off the engine oil.

UNKNOWN OR OTHER
This vehicle does not have a Traction Control Device switch to manually turn off. In snowing conditions and trying to ascend a grade, the TCD activates and eventually you become disabled in the roadway. I looked into the car manual and it does locate where the switch should be located, however my vehicle switch button is a blank button. I phoned my Dealership and reported the problem. They advised other vehicles in their lot did not have the switch as well. No other advice was explained. I reached out to Mazda Customer Car, and they advised me to contact the dealership. Problem remains un resolved.

LANE DEPARTURE: ASSIST, EXTERIOR LIGHTING
1.Instrument cluster panel brightness does not adjust either too dim or too bright Mazda dealer stated no failures were found twice same responded. 2. Lane Keep Assist this feature never worked even on the straight road since I bought July 2022. Mazda doesn't have a capability and mislead the consumers. I found a some report by [XXX] that said Mazda i-ACTIVSENSE received an overall score of 27/100 making it the worst ranked tech in the study. I went dealership service 3 times for repair, but its answers no fault code found no problem at all that they repeated repeated repeated Please investigated this cx-9, Thank You!

Concern is still present. The vehicle vibrates the entire chassis at highway speeds. Mazda states it’s normal but it may vibrate other components loose which could cause an accident. The issue is in the drivetrain

SERVICE BRAKES
The driver side airbag did not deploy in a front end collision on the drivers side. When approaching a vehicle that had come to a sudden and complete stop, the brakes were applied hard to the Mazda CX-9 in order to stop, but after about 1 second they just totally let go and there was no braking at all and the Mazda continued to move forward until it slammed into the vehicle that was stopped. The MyMazda app sent a message that stated that there was a Brake System Malfunctiom which is exactly what occurred and caused the accident.

ENGINE
My 2021 Mazda CX-9 uses excessive engine oil as reported in the Mazda "M-Tip" bulletin MT-005/20 and this manufacturer's defect is reportedly caused by defective valve stem seals as claimed in the class action lawsuit U.S. District Court for the Central District of California, Southern Division: [XXX] v. Mazda Motor of America, Inc. The valve stem seal problems allegedly cause excessive oil consumption between regular oil change intervals, which increases the risk of engine damage and failure. I believe Mazda must address this issue as soon as possible and repair my affected vehicle before I suffer catastrophic engine failure or long-term engine damage.

ENGINE
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.

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.

I purchased this vehicle June 5 2021. The vehicle has approximately 9150 miles at this time. I changed the oil the first time at 3222 miles just because it was new and I wanted to have a starting point on oil changes. The car has an app you load on your cell phone for messages. The first time I received a massage that the engine was low of oil was around 6700 miles. I checked it and it was low with at the add oil mark with 3500 miles driven. I received a second message from the app stating the oil was low. Again, I checked the oil and it was to the add oil level with 9014 miles or only been driven 2300 miles. I have contacted Mazda and will take it to the dealership in a few days, but I am having to add and check the oil ever day or so. There seems to be an oil consumption issue with this engine.

VISIBILITY/WIPER, BACK OVER PREVENTION: WARNINGS
On 4/30/2022 the rear door lift gate opened unexpectedly and hit the ceiling of a parking garage (The Summit at Las Calinas, Irving Texas) , the glass window shattered, glass fell in and outside the car. An unfamiliar beeping was heard before the accident, but the source could not be located prior to the impact with the ceiling. A lift gate ajar warning indicator light likely flashed on the dash but was not noticed. We surmised that the root cause was likely due to unintentional pressing of the rear lift gate key fob button (driver had put key fob in pants pocket). This unintentional and unexpected opening of the lift gate has happened on at least 4 prior occasions when the key fob lift gate button has been unintentional pressed. One time resulting in being hit in the head with the lift gate! Potential Risks: 1) People near the rear of the car can be struck when the lift gate unexpectedly opens, 2) Young children who are sitting in the third seat are exposed, 3) Trunk contents can spill out if not secured, 4) Valuables are exposed if lift gate opens while parked unbeknownst to the driver, 5) Damage to vehicle if rear lift gate opens in a home garage and hits the garage door, 6) other Mazda owners as reported on Reddit.(https://www.reddit.com/r/MazdaCX9/comments/mf3h5w/back_trunk_opening_by_itself/) Problem was reported to TOWN NORTH MAZDA dealer. Insurance claim not filed because cost of window replacement is below deductible. We were grateful that no one was hurt and that the car could be driven home.
