My 4runner was purchased from a dealership and serviced there for rust related problems several times but was never told I had a serious rust problem. The problem is the frame has prematurely rusted and now the car is unsafe to drive due to the control arm rusting off the frame

- Leeds, MA, USA

Vehicle failed inspection due to rust on the frame. Bought vehicle because it is supposedly ruggedly built and for the frame to rust out when the vehicle has 103k miles and not driven off-road for more than a few times since we owned it is ridiculous. Dealer quoted $11k for the frame alone, not including labor. The fact this vehicle shares the platform with the Tacoma which was recalled for frame does not make sense. Vehicle was inspected last year (Virginia requires annual safety inspections), so given the amount of rust discovered makes me doubt whether or not the Toyota dealership did a thorough job inspecting the vehicle last year. We don't drive the vehicle that much so it doesn't make sense that it would rust som significantly.

Frame under the vehicle has severe premature rusting including large holes that make the vehicle dangerous to drive. Vehicle has been inspected, and this is the info that was given to me. Vehicle model/year has seen this issue countless times from other owners, and Toyota has not paid to repair this major flaw from their vehicles. This vehicle has not been inspected by manufacturer, police, insurance representatives, but has been inspected by a body shop/ repair shop. No warning lamps or messages were shown. Vehicle frame has not failed yet, but needs replacement.

Excessive rust on frame, spare tire assembly rusted out, dealer tried to replace tire carrier assembly & winch but was unable to put spare in new assembly holder because of the rust and safety hazard saying it will fall off. I was advise of this today, April 8, at 3:00 pm. The dealership was going to report this to the local Toyota rep and put the spare tire inside the trunk of my SUV. This is a known problem with these 4runner trucks and dealer stated in the past I had superficial rust. I also see there is a pending class action suit and Toyota settle a similar suit with Tacoma and Tundra truck owners for the same rust issues. This vehicle has been well maintained and I put thousands of dollars in repair to keep it running well and trying to keep it safe. I understand there is a pending class action suit filed with the NHTSA August 17, 2018, plaintiff weinreich.

- Clifton, NJ, USA

2006 Toyota 4runner purchased new in November 2006. The frame has suffered from such bad frame corrosion that numerous mechanic have refused to put the vehicle on a lift for fear of complete frame collapse. This vehicle has been well maintained otherwise but is now a definite safety hazard due to the advanced frame corrosion. Service professionals have commented that they have never seen such frame disintegration in a vehicle of this age. I really feel this is a defective frame with rest of the vehicle in satisfactory and operable condition.

Just bought a 2006 4runner and did not think to check underneath for anything. I noticed on the passenger side of the frame huge rust spots, it's rusting from inside the frame out to the surface. It's bad. I googled what I should do to fix it because now I'm out 7K for what I thought was a reliable SUV. They sell patch kits online requiring me to purchase the kits and have them welded to the frame by a professional after they clean the rust completely. That's expensive. Toyota should definitely take this seriously and not fight this claim. No truck that year should rust this bad. In fact I've bought a 77 Chevy C10 that was a farm truck most it's life and it did not have any frame rust what so ever. There's multiple claims on facebook and other 4runner specific groups online that have this same issue. A recall needs to happen. What if I didn't notice and I let my wife and kids ride in the SUV and the frame snaps in half down the highway? you recalled other models do to frame rust, but not the same year 4runner. Please help us 4runner owners fix this because all in all it's a great SUV Toyota makes some of the best product out there, we just want to keep them on the road.

Vehicle's skid plate rusted completely off. Original owners, all family members, have kept the vehicle cleaned well underneath since first day of ownership. When we lifted the 4runner up on a lift, we saw multiple rust holes in the frame as well as extreme oxidation in the center at certain places. I need to have lots of frame repair done to feel safe driving it.

I put my 2006 Toyota 4 runner limited in the shop to have the power steering pump replaced. The shop called me back and stated they refuse to work on the SUV because of the extensive rust damage to the frame. They were concerned about legal issues should they knowingly repair a vehicle that in their opinion was unsafe to drive. In addition, the fuel tank straps rusted away from the frame to a point where the fuel tank was only connected to the vehicle by the skid plate under it.
