| Description of the problem | Oil cooler line failure: while driving on a state route in a rural area my oil cooler line ruptured in my 2009 toyota sienna, resulting in major loss of engine oil, thus being stranded in a rural area and requiring a tow. The metal oil line was constructed with a section of rubber in the middle which deteriorates and fails. Toyota has been aware of this issue for years, and first changed the rubber composition in a replacement part but this part still had a significant failure rate. So the current replacement is all metal line. Why would you have a rubber section in an oil line? Obviously the first two designed parts were a very poor design. Toyota issued an extended warranty for siennas for 10 years and 150,000 miles but this has since expired. I was never notified of the extended warranty. Why expire a warranty if the vehicle is still within the parameters of the warranty (10 years or 150,000 miles)? Toyota says this is not a safety issue. But as a retired corporate safety manager/engineer with a major tire manufacturer i disagree. There are potential fire issues from oil being sprayed on a hot engine/exhaust, a roadside accident potential especially if you suddenly lost oil where you couldn |
