| Description of the problem | Passenger sliding power door stopped working. I manually tried to open the door and it fell off the rear hinge point. I am a mechanical engineer specializing in product testing. I worked in the automotive component industry for 11 years. I can say that this door system is way under engineered. Toyota should be forced to fix this. People are reporting this all over the internet. I called toyota when just the auto open/close system was broken. They told me i'm on my own. That system fails in two ways. 1.) if the auto open/close system fails it should break way from the hinging system so the door will just function manually. Instead it jams the door in the position it broke in. That is a safety issue. 2.) the hinge system is way under engineered for load. I am a 180lb 46 yr old engineer who is soft around the middle. I'm not very strong. I took the door off the hinge! That should not able to happen with such a low force rate. I see this as a safety issue as well. Toyota engineers should be ashamed of them selves. That van cost over 40k brand new. It's only 6 years old and has been well cared for. T's a family/child carrier. It should be designed like a tank in my opinion. |
