3 Power Train problem

Failure Date: 06/22/2019

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't pull off and the motor seized, and a security issue depending on when and where you break down. What if you had little kids and broke down in a rural area (no heat). I will end up paying $94 for a tow, $500 to fix, and 4-7 days car rental to fix. But my biggest concern is the safety issue.

4 Power Train problem

Failure Date: 12/25/2014

The car accelerated to 68. 4 mph. I could not stop car first time with abs brakes. I took my foot off the brake and it helped but it was too late. The car hit the tree. The Sienna's brakes did not work properly at first, the car so how went from 30 mph to 68. 4 mph and the steering did not work. Something has to be done when 1. 2 million dollars of damage to a family. Luckily metropolitan and aetna limited the health care personals. The car was damaged beyond repair. We have new friends called collections companies. Please do not buy Toyota. The corporation considers the accident not their fault.
