The frame is rusted through on this 4Runner. Same frame as the tacomas that were recalled and I’m wondering why Toyota wouldn’t recall THE SAME EXACT FRAME WITH MAJOR RUST ISSUES on a different platform. This truck is not abused so it’s very frustrating to see it falling apart at the frame when everything else is intact and solid. The rot on this frame is inevitable. I’m going to be very upset if I have to pay out of my own pocket for something that should be 100% covered under recall. This is a huge safety hazard and could lead to serious injury or death.

The frame is showing significant rust damage throughout the frame. A hole was punctured in the passenger side while using the factory bottle jack. This could have ended badly if someone was underneath when this happened.

The frame of my 2004 Toyota 4Runner, which is manufactured by Dana Holding Corporation, is the primary support structure of my vehicle, to which every piece is attached. It is the main protection against injury in a car accident. The excessive rust corrosion of the frame on my Toyota 4Runner greatly hinders the safety, crash-worthiness, and stability of my automobile, as transmission mounts, essential suspension components, and engine mounts are attached to it. Consequently, as it becomes affected by rust, it is significantly more prone to failing to protect me, the driver, in a car accident, and, furthermore, it can also cause serious accidents in and of itself. Depending on the gravity of the impact, not only myself but my passengers (my young children) can experience a wide range of injuries and even death. Because the excessive rusting of the undercarriage of my Toyota 4Runners can cause plenty of vehicle components to fail, there can be multiple causes for an accident. The following are the most common injuries people sustain after a car accident: traumatic brain injuries severe whiplash fractured bones lacerations spinal cord damages paralysis loss of limbs permanent scarring concussions internal bleeding head injuries face injuries compound fractures soft tissue damage back injuries dislocated bones knee injuries shoulder injuries herniated disc psychological injuries Unlike in the case of other models of your vehicles, Toyota Motor Corporation refused to address the problem of 4Runners. Interestingly, your company faced a previous lawsuit in 2016 concerning the same rusting problem in the Tacomas, Sequoias, and Tundras, and it was settled for $3.4 billion in 2020. Nonetheless, your company did not admit it manufactured defective vehicles.

My Frame is a rusted mess. The entire frame is experiencing rust issues. My rear sway bar rusted off and broke into pieces (1/15/21). Now my exhaust pipe has fell off the muffler due to rust (7/21/21). My brake calipers have been very badly rusted as well as the pieces that hold my shocks and suspension in place. It has been progressively getting worse over the past 3-4 years. I feel like this has now become a safety issue and I'm not sure if it's safe to drive. It may be a risk to myself and other drivers on the road. My mechanic has told me that it will not improve and he thinks that the frame and other parts should be recalled. I have plenty of photos if needed. Please help me before something goes wrong.
