Vehicle was in for air conditioning service and during inspection the service tech noted rust on the frame of the vehicle, deemed the vehicle unsafe to drive. Vehicle has been services by the same Toyota dealership since 2002 and has performed the same inspection during each visit, why was it just identified during this visit and when the vehicle is unsafe to drive? is it more profitable to not identify the rush to customers and because fix the rust issue or to sell more expensive cars. The dealership deemed that they would not fix the vehicle in a complaint filed through the BBB but would offer a credit towards the purchase of a new vehicle!! this further supports the premise that Toyota intentionally overlooks some issues if they can realize a greater value. Rust identified is on the driver side rear frame. Service tech said about $7,500 to repair at the dealership.

Suspension mount on frame in front of driver's rear wheel broke off due to unusual amount of rust. This impaired control of vehicle at speed, I almost went in ditch as rear of vehicle swayed back and forth severly (like rocking a boat) I had this repaired to continue driving. As of 8-30-15 the same part on other side is almost broken off research shows this to be very common, why is it not addressed?

This is an ongoing issue with Toyota frames. The frames on the 3rd generation 4runner, and the equivalent frame on the Toyota Tacoma are prone to rotting. Toyota stepped up to replace the Tacoma frames since they were cracking in half. Although, the 4runners are suffering from the exact same issues and Toyota is doing nothing about it. I've recently had to remove a 2" X 24" section of frame on the passenger side that was completely rusted through. The frame rot is occurring from the rear lower control arm mount on the passenger side of the car forward until the cross member.

The unfortunate & common frame rust issue that has plagued thousands of owners of this model Toyota has now affected us. Safety concern quite high since the structural integrity is severely compromised due to a design flaw as noted countless times by numerous 4runner owners. This issue is identical to that with Tacoma frames of the same vintage (which are identical in design & build to that of this model style 4runner), which was addressed by Toyota motor corporation. Yet no recall to assist 4runner owners has been executed. It appears that Toyota is allowing vehicles to become prematurely unusable & unsafe for consumers. Toyota has either replaced some frames on similar vintage 4runners or has provided reimbursement to owners suffering from premature failure... but only very sporadically. I have contacted Toyota motor corporation & was told their is nothing that they are going to rectify for us, yet there are others that do receive a resolution of some kind. As a paramedic I see first hand what tragedy occurs on our roadways... and this situation worries me greatly with vehicles that are supposed to protect it occupants in the event of a crash, but may now actually contribute to the unnecessary harm or possible death of it's occupants/operators.

The frame has suffered serious rust through also described as "frame rot" in postings on line of Toyota 4-runner problems. This rust through has made the vehicle unsafe and currently unusable. The rust was discovered when the entire rear axle was replaced at my expense. Toyota would not allow that they were responsible for faulty manufacturing of the rear axle either which was yet another safety concern.
