Due to severe rust underneath the vehicle, there have been a few issues that have made the vehicle very unsafe to drive. Last week, both of my rear brake lines were completely done and leaking brake fluid leaving me with no brakes. This was due to rust and corrosion that had eaten the metal lines away. The radiator mounts are corroding, as well as the skid plate for my fuel tank and a few spots on my frame near the rear. I was not aware of the rust as I just got the vehicle a few weeks ago. I was driving in traffic when my brake light came on and I noticed my brakes didn't seem to be very effective and they eventually got the point where they were not working or slowing the vehicle at all. Once I took it to the shop and they put it on the...
No Accident - Items need to be investigated for Safety Defects on Toyota's. 1> Front Brake Calipers (constant freezing of the front brake calipers). 2> Dash Cover (excessive cracking on the dash covers especially areas that contain airbags). 3> Fuel Pump Connection (on top of fuel tank, connection to fuel pump appears to create a short, which in turn causes vehicle to stall also could cause a fire). 4> Excessive Frame Rust (frame has excessive rust outside and inside which is causing frame to fail. this is a manufacturing issue).

I WENT TO TOYOTA AND THE FIRST TECHNICIAN NEVER HEARD THAT HAPPENING BEFORE BUT ANOTHER OVERHEARD OUR CONVERSATION AND SAID "I BET YOU HAVE A 4RUNNER" SO YEAH ITS HAPPENED TO OTHERS. THEY WANTED NEARLY $4500 TO FIX THE ISSUE. NEW ENGINE WIRING HARNESS $1500-$2000 AND ANOTHER $1000 FOR THE LABOR AND THE REST OF THE ESTIMATE IS FOR OTHER PARTS NOT SPECIFIED. THEIR SOLUTION IS TO CUT THE WIRE BELOW THE TRANSMISSION WIRING...
