Crankcase (pcv) problems of the 2022 Audi Q5

2022 Audi Q5 (VIN: [xxx] ). Engine lubrication system failure — persistent abnormal oil consumption across two separate engines over 14 months. Beginning March 2025, the low engine oil warning light began activating repeatedly, sometimes after as few as 300 miles. Autonation Audi bellevue confirmed 1 quart low and initiated oil consumption tests. Their technician noted in writing that oil found externally was "not enough to cause a 1 quart low oil light" — meaning the root cause was never identified. A pcv valve replacement was attempted July 2025; the warning returned after only 300 miles — same as before the fix. Audi of America approved a full engine replacement in September 2025, completed December 2025. Within weeks of pickup in January 2026, the low oil warning activated again on the brand new engine, and again after 4,000 miles in April 2026. The defect has persisted across two engines despite multiple repair attempts. Audi now claims consumption is "within spec" at 0. 16 qt/1,000 miles but has not explained why the warning light keeps activating. Safety risk: unpredictable oil loss risks sudden engine seizure at highway speeds with insufficient warning to stop safely. Confirmed and inspected by autonation Audi bellevue and Audi of America. Vehicle available for inspection. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
