My car displayed a low oil level light between oil changes and after checking the dipstick it was low. No sign of visible oil leak so upon further research I was made aware of a TSB about defective valve seals causing excessive oil consumption. My cars VIN is in the affected range outlined in the TSB. Now when I drive it's likely that slow but permanent damage could be occuring in my vehicle.

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 engine oil low light has illuminated multiple times. I verified that there is no external engine oil leak. I have added oil and driven it for a couple thousand miles and the light is now on again. The car is brand new and should not be burning oil. Its a known issue as Mazda has a service bulletin but no fix for it. This is the bulletin number TSB-01-012/21.

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.
