While driving normally and less than 10 miles per hour, thankfully on a regular, paved, local road with little traffic, the driver side rear suspension spring seat and stabilizer bar attachment point on rear axle suddenly, unexpectedly, and without warning just tore apart and off of the axle housing to which it was mounted and the resulting sharp and heavy metal edged parts completely sheared off a brake line releasing all hydraulic brake fluid and causing the immediate loss of all normal braking ability. Thankfully nobody was injured, but the car can't be driven at all now, because it has no brakes at all, other than the mechanical emergency brake, and by using transmission "braking. " lots of rust under car since we bought it used from dealer in morristown NJ, apparently due to low quality steel used in initial construction and apparent lack of adequate factory anti-rust treatment of frame and other undercarriage parts. Interior and painted top body parts show no rust issues. However, the underside, is full of lots of rust. This is apparently a well-known, very common problem with Toyota fj models. It is very dangerous, and it should be addressed by Toyota immediately! I'm making plans to have the car towed to a local Toyota dealership for inspection and possible repairs. Finally, as far as I am aware, this car has never done any significant or taxing "off-roading. ".
I have had two brake lines burst in the past year due to rust. Both times I was lucky to not have been on the interstate and was traveling at a low speed. Both have been the back brake lines. This rust situation with the fj's is unacceptable and dangerous! Toyota should be held accountable and the situation needs to be addressed before a person is killed or seriously injured.
