2021 Mazda CX-5

Low engine oil light appeared despite standard maintenance service and oil change at Mazda dealer the prior month. Service technician confirmed oil was low by 1 and 3/4 quarts and added oil. Mazda dealership advised there is a service bulletin for my vehicle with this problem dating back to 2021, and that the problem is likely due to a faulty valve, but that they have no planned fix available. I am concerned about the long-term damage of engine oil continually leaking into the combustion chamber. Mazda should be asked to fix this for car owners, not simply top off our oil each time that it leaks.

oil consumption on a 2021 Turbo CX-5. problem has been reproduced and confirmed by dealer. warning lights twice. first time told it was normal. happened twice. only on my third maintenance oil change was it acknowledged. had to do a lot of research on my own. caused enormous stress to existing mental health issues. would not have even been addressed had i not stated the issue.

Engine is either burning or leaking oil. The low oil light flashed after a 2hr highway trip (traveling to my parent's house for Christmas with my wife), low oil was confirmed the following day via dipstick. Oil was changed at the dealership about 4 months ago, mileage is under 24k miles. Looks to be related to this service bulletin, which still does not appear to have a fix or recall associated with it. Mazda Oil Consumption TSB Turbo Engines Components: ENGINE AND ENGINE COOLING, TIRES, ELECTRICAL SYSTEM NHTSA ID Number: 10202685 Manufacturer Communication Number: 01-012-21-3832 5 Affected Products Vehicles MAKE MODEL YEAR MAZDA CX-30 2021 MAZDA CX-5 2021 MAZDA CX-9 2021 MAZDA MAZDA3 2021 MAZDA MAZDA6 2021 Summary Some vehicles may have a LOW ENGINE OIL LEVEL warning message and a CHECK ENGINE light illuminated in the instrument cluster, along with DTC P250F:00 stored in memory. DTC P250F:00 - Engine oil level signal: engine oil level low. Upon inspecting the engine oil level, the level is found to be low and there doesn't appear to be any trace of oil leakage in the engine compartment. This concern usually occurs when the mileage reaches approximately 3,100 - 4,700 miles (5,000 - 7,500km) and may also occur again after replacing or topping off the engine oil. The root cause of this concern has not been identified yet, therefore a repair procedure will be announced at a later date. Since this issue has been reported after a valve stem seal modification, it is very likely that valve stem seal damage is causing oil to leak into the combustion chamber.

When I reached 7000 miles on my car the low oil light came one. I immediately drove it to the dealership - ending a vacation early as I thought something was seriously wrong with the car. I got to dealership and they blamed me for getting an oil change at a competitor and not putting in enough oil. They then changed the oil and again at 12000 the low oil light came on. There seems to be an oil consumption issue that Mazda is NOT admitting to or fixing. Every time I drive more than 4500 miles the car is 1/2 a quart low and it warns me. Now the dealership wants me to spend HUNDREDS of dollars on a vehicle in warranty for oil consumption testing....though there is no leak and no soot in the tail pipe.

At 16,550 miles (5675 miles since the last oil change), my oil pressure light came on. Per owner's manual, I turned the car off & let the oil drain into the pan for 5 minutes. I checked the oil but due to it being so hot it was hard to get an accurate reading. I turned the car back on & the oil light was off. I proceeded to drive into town and 25 miles later the light came on again. I checked the oil & it appeared to be very low. I added a quart of oil and the light went off. I checked the oil level later when the car was cool & the oil level on the dipstick was now halfway between the 2 dots on the dipstick. I drove about 300 miles home from our trip and the light never came back on. I took it to the dealership the next day & the technician said no codes showed that my oil level was low and they said my oil level was now 2 Qts too high. I only added 1 and they changed it last. Even though I was told there was a known issue involving a valve stem seal, they told me Mazda will not authorize the repair unless the engine code error is present (P205F?) & the low oil light is on. They were unable to explain why my low oil light came on. I was told that I need to change my oil every 5k miles even though the owner's manual says I can go up 7500 miles. They also told me that I should wait 10-15 minutes to let the oil drain after shutting the car off and not the 5 minutes that it states in my owner's manual. They told me if this issue happens again, to have my car towed to the nearest Mazda dealership. However, again the repair would only be done if both conditions were present. A bulletin had been produced on this issue but not provided to the owners of the vehicles. This is a safety risk since I was on a trip and would never imagine having this issue with a new car 1year old. Had I known this was an issue, I could have been more prepared. Potentially letting oil continue to seep into the combustion chamber of my engine is not ok.

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.

My car appears to consuming oil excessively. I bought this car new in March of 2021 at I have had to top off my oil between oil changes at almost every single oil change since I have owned it. The car only has 33900 miles on it and usually about two months in from my oil change the check oil light comes on and the dipstick shows the oil at the lower end of the dipstick. I have purchased oil on my own and have had to have the dealer top it off. After topped off it will usually make it fine until my next oil change but a brand new car should not be burning oil like this and I was told they have known about a valve stem defect since September of 2021 but still have not done a recall or have a fix for it.
