I was informed by my mechanic that my vehicle has extensive rust and corrosion on the vehicle frame.I understand there was a recall on this issue by Toyota but did not include this model year. This issue affects not only driver safety but also resale value.

How was your safety or the safety of others put at risk? Response: Safety was put at risk due to frame & suspension failure due to severe rust. Also due to failure of deployment of AirBags. Rusted Frame Failure subsequently caused safety of Injured Party and other motorists to be at risk due to the Injured Party’s 4Runner to dart across oncoming lane of traffic with no warning other than a swaying motion felt immediately before losing control. Once the Injured Party lost control of the 4Runner it crossed into oncoming traffic, progressing into the drainage ditch on the oncoming traffic side of highway. Once the 4Runner impacted the drainage ditch at a 90° angle, the 4Runners momentum dispersed by causing the 4Runner to overturn 3 times landing on its wheels in the adjoining field.

2004 Toyota 4Runner SR5 - Frame rust: currently not drivable due to complete breakage from the rust. Driving 2 hours home on the highway I almost lost control, pressing/releasing the brake and/or gas pulls the steering side to side and sways the truck (fish tail) due to damage from the frame rust/breaking. There is no control of the rear end. Truck was in great condition prior to the frame snapping. Vehicle has been inspected by multiple mechanics (including Firestone, Welding/fabricating Auto Repair shops and small owned mechanic shops), possibly won’t be able to weld due to the amount of rust. Firestone won’t perform any service if the vehicle needs to go in the air (tires, oil..etc) due to frame rust. This has been a huge problem with Toyota, they addressed other models around the same year but excluded the 4Runner for unknown reasons. The dealership will not address the issue unless instructed by corporate. This problem jeopardized my safety and the safety of others around while I was driving at highway speeds, there was no warning when it occurred. Vehicle is available for inspection any time, as it currently is not going anywhere without a tow.

I recently bought a 2004 Toyota 4 Runner and the frame of the vehicle has significant corrosion to the extent of holes, weld failures and more. I've never seen frame rust so bad on a vehicle like this. I'm a little uneasy about the safety of this situation. I think Toyota should replace the frame or give a good discount on the part and labor. I hope someone can help me out with this concern.

Took 2004 Toyota 4Runner SR5 to Toyota dealership to be serviced. Dealership called me to explain unable to do alignment, due to rear back frame excessive rusted through. Dealership advised waste of money to align new tires just purchased, unable to even do alignment and it was dangerous. Now what is to be done? This is my daily driver for work. How did this happen that its unsafe and dangerous to drive.
The rear tailgate window shattered while vehicle was in driveway as soon as it was turned off. Before it shattered there was an odor of something like plastic burning. Fortunately no one was hurt by the exploding bits of glass. The sound the breaking glass make was loud and startled the passengers. Good thing the vehicle was not in motion on the street or highway. On the internet I saw where other people shared the same problem on their Toyota 4Runner. Then I saw that Toyota had put out, TSB-0189-17, which stated exactly what happened to my 4Runner. Due to this possibly dangerous incident this should be upgraded to a vehicle safety recall.
2004 4Runner rear hatch glass imploded with rear defroster on while driving and glass shattered all inside the vehicle in the back behind rear passenger seat. The loud sound when it imploded sounded like we had got shot at and scared all four of us in the vehicle thinking we were shot at. We pulled the vehicle over at the nearest pull over while driving on a coastal two lane road. We searched for any possible bullets. Did not find any and had to clean up as much possible of shattered glass that had covered all of our clothing and belongings. Had no materials to cover the rear broken window and had to continue our drive to meet family members to attend an early event at 9:00 am.

Unknown: we were on [XXX] when the car went out of control. It first spun one way and then the other way and then we hit the concrete abutment where the guardrail connects to it. We hit it head on. It was as if we were on ice or oil, unable to gain control or brake. We checked the road and it was dry. Other cars were going by with no problem. The airbags didn’t deploy.

I have taken my car to Mountain states Toyota as well as corwin toyota for a tripped light it has to do with vehicle stability system it trips leaving the vehicle stability option not usable. I have told both dealers not to just reset the code however this is what’s happening and they don’t seem to know why it’s doing this. we have repaired the knock sensors and speed sensors. It feels unsafe driving when this trips when road conditions call for all wheel drive. the technician can’t figure it out why. their only solution is to keep resetting. This is not the option I want I need it repaired and they don’t seem to want to do it or figure out and give us options on repair.
