Crankcase (pcv) Problems of Audi Q3

I am reporting a serious safety concern involving my 2017 Audi Q3 premium plus, VIN [xxx]. The vehicle is experiencing excessive engine oil consumption requiring frequent addition of oil. I reported the oil-consumption problem shortly after purchasing the vehicle. Audi coral springs recently diagnosed the vehicle and recommended substantial repairs. The dealership identified a crankcase breather/pcv condition causing oil to enter the intake system and also recommended replacement of the timing chain. The total recommended repairs are approximately $10,000. Audi's current diagnostic scan also identified multiple camshaft/timing-related engine fault codes, including p0011 (camshaft timing over-advanced/system performance), p0341 (camshaft position sensor range/performance), and p000a (camshaft position slow response). I am concerned about continuing to operate this vehicle because the engine is consuming oil at an abnormal rate. If the oil level or oil pressure becomes critically low while the vehicle is being driven, I am concerned about engine damage, engine failure or loss of power while driving and the potential for an engine-related fire. Of particular concern, while researching the vehicle's history I found a previous NHTSA complaint associated with this same VIN describing excessive oil consumption involving the pistons and/or piston rings and expressing concern that the condition could result in an engine fire. That complaint also described epc/check-engine/low-oil-pressure warnings and stated that approximately $10,000 in repairs had been quoted. I am now experiencing excessive oil consumption in the same vehicle and same VIN, and I have also received an approximately $10,000 repair recommendation. I am requesting that NHTSA review this complaint together with the prior complaint associated with VIN [xxx] and determine whether the repeated excessive-oil-consumption condition in this vehicle. Sincerely, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
