| Description of the problem | With about 6000 miles showing on the odometer, and children present in the vehicle we suffered from a manufacturing defect; a complete mechanical failure that was life threatening. I was on an on-ramp preparing to enter the freeway when i felt the under carriage of the vehicle slam down. The rear differential disintegrated, and the vehicle was unable to accelerate or be put into gear. With tremendous effort and horrendous noises the vehicle could struggle to move at about 5 mph. Once the dealer received the vehicle the toyota representative. Appeared within days to inspect, collect, and later analyze the failed parts. The transfer case and rear axel assembly were replaced. We cannot and will not be picking this vehicle up from the dealer due to the unexplained and dangerous events that have occurred.*ak |
