Engine Oil Leaking problems of the 2011 Lexus RX350

My 2011 Lexus Rx350 has rubber oil cooler hose and Lexus USA will not replace the pressurized rubber hose despite known incidents of catastrophic failure of the part. On some Rx350 models, Lexus has an extended warranty and replacement in case the part is leaking oil, but I was told by Lexus that my particular VIN is not eligible for the extended warranty. But even if I had the warranty, Lexus will not preemptively replace the part, despite 1) safety concern of failure on highway at high speeds and fire hazard risk, 2) potential catastrophic engine failure as the line would rupture and all oil would be lost within seconds and engine would seize and 3) potential environmental damage of loss 6. 4 quarts of oil over roadways. Please consider advising Lexus to do a safety recall on all rubber oil cooler hose parts. Thank you.

1) engine oil leak at 15,000 miles only on may 8, 2013 (after merely "2 years old") 2) another 3 leaks in year 2015 alone a) engine oil leak again on March 27, 2015 ( 33,802 miles only ) b) less than 2 months, engine oil leak again on may 7, 2015 ( 35,284 miles only ) c) repeat the 4th time engine oil leak again on Dec. 26,2015 (44,013 miles only ) *** per all 4 repair service invoices/records provided by longo Lexus dealership, California, this is major engine oil leaks problem!!!!.
