NHTSA Complaint #11719381 — 2011 TOYOTA CAMRY

Dear NHTSA Investigators, I am writing to formally report what I believe is a significant safety defect in certain 2007–2011 Toyota Camry vehicles, specifically related to excessive engine oil consumption in models equipped with the 2AZ-FE 2.4L four-cylinder engine (primarily 2007–2009, with some reports extending to later years). This issue causes the engine to burn oil at an abnormally high rate—often 1 quart or more every few hundred to 1,200 miles—without any visible external leaks. Owners frequently report no adequate warning from the dashboard oil light or other indicators before the oil level drops critically low. If the engine runs out of oil while driving, it can lead to rapid overheating, internal component damage (such as scored bearings or cylinder walls), and sudden engine seizure or catastrophic failure. Such a failure while the vehicle is in motion poses a serious safety risk, including: potential for crashes, including rear-end collisions if the vehicle stops abruptly without warning, or veering into other lanes/obstacles. Sudden loss of engine power. Increased likelihood of loss of control etc. This problem has been widely documented through thousands of owner complaints (e.g., hundreds on sites like CarComplaints.com for the 2007 model alone), NHTSA ODI reports, and Toyota's own Technical Service Bulletins (TSBs) and Warranty Enhancement Programs (such as ZE7 for certain models). While Toyota addressed it via a warranty extension (not a full recall) involving piston/ring replacements for qualifying vehicles after an oil consumption test, many owners—particularly those outside the original coverage period or with higher mileage—have faced expensive engine repairs or replacements out of pocket. The lack of a mandatory recall means the issue persists in many vehicles still on the road. I am concerned that this defect creates an unreasonable risk to drivers, passengers, and other road users. I had an issue with this and I needed to fill up 4.5Q
