“Takata recall . So I'm not understanding a problem with my Toyota 4RUNNER. As of yesterday there was a great amount of smoke coming from the area of the oil stick from my assumption the oil was getting on the cadillac converter. Or something that would hit something hot on the engine to cause it to smoke I'm trying to find out if there is a recall for that.”
NHTSA complaint #11180693, filed 2019-02, 185,000 miles“I was at a complete stop. Right after I let my foot off the brake, the car lunged forward violently. It was a traumatic experience. I don't know if this was an isolated incident, will it happen again or is this common? Also, shortly after I took ownership of my car, the paint started to peel on the rear hatch below the license on the left, where there are somewhat sharp angles. Toyota repainted the rear hatch, excluding the spoiler. I just noticed two rust spots above the rear window. …”
NHTSA complaint #11374367, filed 2020-11, 58,000 miles“The frame on my 2003 4RUNNER has rusted to the point of breaking. Toyota had a recall on the tacoma of the same year for this issue and that vehicle has the same frame. As an owner of a 4RUNNER I am upset because my vehicle costs more, but Toyota will not fix this.”
NHTSA complaint #10860464, filed 2016-04, 75,000 miles“This 2003 4RUNNER has 85k miles on it and has severe rust on the front corners of the frame. The safety of driving this vehicle is questionable. There's also significant rust on other metal components as well. I previously owned a 2006 tundra that was recalled for severe frame rust and I know several other people that had tundras and tacomas with severe rust problems on the frame. The 4RUNNER has a truck frame under it like the other Toyota trucks and has the same frame rust issues. Why is there no recall for the 4RUNNER?”
NHTSA complaint #11338422, filed 2020-07, 85,000 miles“The frame of my vehicle is extremely rusted for it's age. Every component attached to the frame is overly rusted as well. It is spreading like a virus throughout the under body. I am becoming increasingly concerned about hauling, towing, or even driving my vehicle due to this rust. With only 172,000 miles, this should not be occurring. I have been keeping it in a garage for the past 5 years but as the 2nd owner it's probably too little, too late. Toyota should recall these vehicles as they did some other models.”
