“Airbag warning light intermittently flashes, upon personal research on owner forums this is a common issue that is most commonly fixed by wiggling or disconnecting/reconnecting the airbag sensor wiring below the front seats.”
“The contact owns a 2006 Toyota Sienna. The contact stated that while the vehicle was at the dealer for a recall repair, the mechanic discovered large holes in the center of the subframe caused by rust. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 218,000.”
“The vehicle stability control system randomly engages and activates the brakes without cause. This can happen on a gentle curve going under the speed limit. It is very scary and I am afraid it is going to cause an accident. Internet research shows many owners with this issue and no information on the cause or a fix”
