Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“During a state inspection the shop told me that our 2005 Toyota 4RUNNER had some frame rust issues. Since the frame of the 4RUNNER is the same basic unit as the tundra and tacoma that have open recalls for frame rust, the 4RUNNER should be included in the same recall. As you can see in the picture of the aft frame, the corrosion has formed large holes in the frame.”

NHTSA complaint #11182519, filed 2019-02, 140,000 miles

“My 2005 4 runner chassis is rusting away and multiple dealerships and mechanics told me the car is not safe to drive. I went to get new tires and no locations will even raise the car in the air. I called Toyota corporate and even though the same chassis on the same vehicles of tacoma, tundra, and sequoia are recalled, they said nothing is covered under the 4 runner. I cannot even drive my car anymore.”

“I am having deep rust issues on my 4RUNNER v8 limited frame mostly near the catalytic converter. The rust is so bad there is a big hole on both size of the frame 3inch tall 7 inch wide. I have found some loose nuts inside of the frame rails, not sure where they are from and there are a lot of broken frame parts on the frame rails. A 13year old truck shouldn't have that much rust”

“I just bought this 4 runner used and I've all of a sudden had super bad rusting around the frame and also around the radiator and where the skid plate is attached where my mechanic says he's worried about my safety and other drivers on the road, I personally feel like the integrity of the framing system and suspension is being flawed and I believe that I and the millions more that are being effected by this should be taken care of.”

NHTSA complaint #11387783, filed 2021-01, 159,900 miles

“I love my 4RUNNER and would like to drive it for many more miles as it runs and drives great. But the frame is rusting out, just like the tacoma and tundra frames that were recalled by Toyota. 4RUNNER frames should also be recalled for prematurely rusting out and causing safety concerns”

NHTSA complaint #11253729, filed 2019-09, 200,000 miles
