The main rust issues are claims arising out of a pending class action lawsuit pleadings’ that the Toyota Manufacturer perform at no cost inspections, in addition to dire emergency needed replacement of including my 2003 Toyota 4Runner frame because of premature rusting of the undercarriage-my vehicle’s frame due to improper treatment against rust corrosion during manufacturing-inadequate rust protection, which has lead to severe excessive rust corrosion significant enough to affect structural integrity, compromising the vehicle’s safety, stability & crash-worthiness, & poses a dangerous risk.

While driving my ABS, break, vsc trac and vsc off light came on solid. It was all accompanied by an alarm. I was in heading down a hill in the snow. Right after the alerts came on I had a hard break pedal with no movement and no breaks. I was not able to use the emergency break as in snow that would not have helped. I have done some research and this has happened to multiple people online and its concerning that if ABS stops/faults you lose all ability to break at all.

Tl* the contact owns a 2003 toyota 4runner. While driving 65 MPH, the vsc and traction control warning indicators illuminated. The anti-lock braking system engaged and locked the front brakes. The vehicle violently pulled to the left lane and the steering and brakes failed. The dealer was unable to duplicate the failure and repair the vehicle. The manufacturer stated that they were unaware of the failure previously occurring. The failure mileage was approximately 167,000.

I've been doing research online for the non stop vcs trac, vcs off, ABS and brake warning lights and buzzers going off. It has been described as a common issue with toyota and can lead to complete loss of brakes, but no recall. The dealership wants $3200 for the part and $600 to install. I guess toyota needs fatalities to back their product. Shame on toyota.

Near the end of august four warning lights came on at the same time in my 2003 4runner. They were the vsc trac, vsc off, ABS and brake. I scheduled an appointment with the local toyota authorized repair shop to determine and fix the problem. They looked at the vehicle and discovered significant rust and corrosion on the frame, rear axle and attached parts. I have asked for an estimate to repair, and they are unable to do so as there is so much rust, corrosion, and lack of material to work with. I am the second owner of this vehicle. The first owner, a friend of mine, had the vehicle undercoated the day after purchase, kept the car in a garage, and washed the vehicle frequently including the underside. I purchased the vehicle in february 2007 with 13,750 miles. It has also lived in a garage here. As of august 29, 2013, the date of the inspection, the vehicle had 24,005 miles. The exterior of the vehicle is in perfect condition, and the interior is the same. However, the underside is a different story. I have contacted toyota and received this response. "there are no known issues or current recalls relating to body and frame rust issued for your vehicle...your vehicle is out of warranty, and we would be unwilling to offer you any compensation for any repairs to the vehicle. While we understand your dissatisfaction with this decision, it does represent toyota's final position in this matter."

I purchased a brand new 2003 toyota 4runner in may 2003. In one cold morning of jan. 2005, I was driving it in highway that was still covered with some snow. All of sudden, an engine check light on the dashboard was automatically turned on, followed by vsc lights, indicating that a vehicle skid control function was automatically turned off. At that point, I could not drive the car beyond 50 MPH, no matter how hard or frequently I pushed the accelerator pedal. I pulled over, restarted, and re-entered the highway but had the same results. I managed to drive the car to a dealer for inspection the same day. The dealer could not find a cause and simply reset the computer controller. This seemed to have resolved the problem at that time. However, the engine check and vsc light issues resurfaced about two years later. The difference this time was that there was no acceleration issue. No inspection was made. The dashboard lights were automatically turned off after driving for about a month. In jan. 2010, those lights reappeared and have remained turned on. No impact on acceleration has been observed.

While driving uphill in the snow, the automatic stability control on my toyota engaged with a beeping sound and a dashboard indicator light. Once this happened, several other lights illuminated on the dashboard and the vehicle began to accelerate up the hill. I attempted to brake, but the vehicle continued to gain speed and struck the back of a parked pickup truck on the side of the road. No airbag deployment occurred. The front end damage was significant, making the vehicle a total loss.
