Brand new bought Toyota Sienna 06 with 31k miles the doors started making noise. I read up on this on some websites and it appears that there is poor welding / bad deigns on Toyota Sienna doors.
Was out shopping, went to open the rear door when I realized the struts were not lifting the door. I inspected the struts ,and realized they had exploded and were leaking. No failures of the rear door previously; door was working properly the day before this incident. Have an appointment with Toyota dealership to correct the problem. Cannot use the back portion of the minivan to store items since door was not functional. I am glad the door did not fail when it was opened and someone was underneath, especially one of our kids. I have read on the internet that this has happened with other Toyota Siennas.
The contact owns a 2006 Toyota Sienna minivan. While trying to get into the vehicle the driver's side door squeaked. The contact attempted to oil the doors and they continued to squeak. The failure mileage was 24000. The dealer stated that the vehicle needed a new door due the separation in the door welding. The dealer informed the contact that it would take one week to install the door. Also, the contact was upset that after painting the door it will not match. The current mileage was 25,000. Update 4/9.
