NHTSA Complaint #11483004 — 2021 MAZDA CX-5

Vehicle has had excessive oil consumption. Engine consumes approximately one quart of oil every 4k miles or so with normal driving not spirited. Vehicle has no visible signs of outward leaks. First oil change was at 5030 miles with approximately 5.2 quarts of Castrol edge full synthetic oil and a Purolator boss oil filter PLB14612. Vehicle currently has 9352 miles. I have not let it get to a point where oil light comes on, but it has been to the quart low dot on the stick twice so far. This should not be normal. This has not been confirmed by a dealer or independent service center as I maintain the oil checks and oil changes myself. Tailpipes do have black soot inside but is not greasy or oily. I haven't noticed a lot of smoke from tailpipes just a small bit of whitish vapor that quickly dissipates when my wife pulls it out of the driveway and starts off down the road that I contribute to normal condensation, but I nor she can see tailpipes when we are driving a longer distance of course. I haven't smelled oil burn or seen any leaks on driveway, but the oil is going somewhere. I have seen a TSB from Mazda about possible valve stem seal problems with my VIN number. I hope Mazda will resolve this within my warranty as oil consumption can cause other major engine component damage down the road i.e., catalytic convertor, oxygen sensors, carbon deposits, etc.
