Open the full vehicle complaint log (all categories)Noticed rust on suv/frame confirmed by Faulkner Toyota Dealership, mechanic informed too address this problem soon.
Excessive underbody and frame rust.
GENERAL PERSONAL USE. FRAME IS RUSTING AT AN ALARMING RATE. I FEEL IT IS CRUCIAL FOR ME TO GET THE EXISTING RUST REMOVED AND THE FRAME PROTECTED IF I WANT THIS VEHICLE TO LAST ME A REASONABLE AMOUNT OF YEARS WITHOUT ANY STRUCTURAL FAILURES. IT HAS A LITTLE OVER 100K MILES ON IT.
I AM ONE OF THE MANY WHO ARE EXPERIENCING RUST PROBLEMS WITH MY FJ. RECENTLY HAD TO HAVE ALL CALIPERS REPLACED DUE TO RUST. OIL PAN COVER AND COMPONENTS AROUND IT ARE STARTING TO SHOW SIGNIFICANT RUST. RUST IS IN THE EARLY STAGES IN SEVERAL AREAS OF THE FRAME BUT VERY EARLY STAGES. I AM CONCERNED THAT THE RUST WILL BEGIN TO AFFECT THE SAFETY OF THE VEHICLE.
EXCESSIVE RUST ON THE UNDERSIDE OF CAR - ALL OVER THE FRAME AND AXELS

Widespread problem in the United States with excessive rust compromising the stability and safety of the vehicles. Toyota authorized Dealerships are no help.
