Chassis, brakes and all under carriage of 2004 toyota 4 runner is rusted. soon the car will not pass inspection. i do not live in a salt water zone. my car has never driven through salt water. i have 71,000 miles on the car. the brakes were so rusted that i had to replace them. the car will be too dangerous to drive soon.

Frame rail rotting and i've always parked in a garage!

Frame found to be rusting away and can not be safely inspected. was told by safety mechanic areas are very bad and parts may start falling off.

I own a 2004 toyota 4runner with significant rust on the frame that has nearly rusted through in some areas. through my research i determined that this has been an ongoing issue for many toyota vehicles close to the 2004 model year. apparently the frame was not properly coated and rust has grown on my vehicle as well as many others at a much faster rate than is typically expected. i am worried about the safety of my vehicle as a result.

The frame on my 2004 toyota is very rusty. it is completely cracked through near the front passenger suspension. my mechanic has warned me not to drive the vehicle anymore. see pics

I brought toyota 4runner 2004 in for a recall and the dealer told me there was major rust on frame . he showed me pictures of the frame rusted through in many areas. he told me it was dangerous to drive . i have a toyota tundra which had similar rust on frame and toyota put on a new frame . this car is unsafe to drive .

The frame of my truck is complete mush! i've taken excellent care of my 4runner as it has been my most favorite vehicle. i'm being warned to get this fixed due to it being a dangerous situation & wouldn't you know i'm driving home & i loose all control over my vehicle on hellacious mountain roads, brakes completely gone! everything rotten! why weren't we notified how dangerous these trucks truly have become?

There is a crack in frame on passenger side never in accident . the rust corrosion is horrible almost cracked all the way on drivers side ,front hooks gone from rust.

Rust crack in frame right front at core support. cracks in dashboard.

I just took the car for annual state safety inspection. it failed and the inspector said it is unsafe to drive. the part of the frame that connects the right front and right rear suspension is so rusted that the car is unsafe to drive. we have been driving this vehicle with no knowledge of this hazard.

Took my 2004 toyota 4runner in for a brake job and the mechanic asked if their was any recalls on our vehicle for rusted frame .he said that we were going to have trouble with it soon do to frame rusting so bad

Frame rust issue..... very bad frame rust behind the front bumper, below the radiator support. rusting so bad that radiator support will need to be reinforced.

Transmission failed due to rusted transmission lines. leads up to finding out that frame is completely rusted out. unable to fix it due to frame rust. suspension are of frame rusted as well...barely holding on. traveling from tn to pa when all this happened.

The frame of the vehicle is developing a hole on the bottom right side frame rail around where the trans mission cross-member mounts to the frame

Under carriage , frame rust through very similar to the toyota tacoma frame rust through.
