CarComplaints.com Notes: Although the 2003 model year is the "worst" model year for the 4Runner, it's not really bad at all -- mainly it's just that the other 4Runner model years are even better. Howver the 2003 model year has no major problems & no unexpected problems for a 17-year old vehicle. We award the 2003 4Runner our Seal of Awesome, since overall versus other comparable models of the same age, it's very reliable.

Initially the 4th generation (2003 - 2009) 4Runner didn't earn our top "Seal of Awesome" rating because it received poor crash test ratings for rear impacts. However it's proven to have one of the lowest driver death rates out of all vehicles (not just SUVs), so we've bumped it back up to our top award.

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.

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.

problem #2

4Runner

  • 50,000 miles
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.
