problem #2

Mar 232015

4Runner 6-cyl

  • 80,705 miles


December 2014, found my driver's side tail light and brake light out. Replaced the bulb twice; did not work. Replaced the fuse; did not work. Took it to the local dealership in March 2015 which found the tail light has an "excessively high voltage" which continues to burn out the bulb. The repair was to replace the entire driver's side tail light assembly at a cost of $290. There was no recall or tsb so repairs came out of pocket. This is an extremely dangerous condition that could have resulted in a fire. This vehicle is designed to hold multiple passengers, of which my two children often accompany me. I'm not sure how safe it is to drive even after the repair.

This complaint concerns the new 2010 Toyota 4runner. There is an issue with the braking system and handling for this vehicle. Upon depressing the brakes, the pedal travels a considerable distance sounds squeaky and notchy and delays in stopping. The anti-lock brakes do not interact quickly and often times engaged at the very end of the brake distance and creates a very uncomfortable and unsettling feeling. The height clearance is also a concern because when cross winds hit the vehicle it creates a very unsettling feeling and causes the vehicle to sway and get under the vehicle making prone to loss control. That wind does not have to be excessive; the mildest of winds will cause a disruption. Several measures have been taken to have a local Toyota dealership review and address the issue and they have come back and stated that it operates according to specifications. No one other than Toyota knows of those specifications and they will not disclose them until enough people highlight this issue by complaining. To add further insult to injury, Toyota has placed an administrative hold on any repairs unless they sanction it. In one of the latest uses, I had a deer cross my path and I tried to stop and the vehicle kept moving along and the brakes grabbed after 12 feet. I missed the deer but I was forced to relive the issue of how faulty the brakes are for this vehicle. It reinforced the issues with the braking system. We need for Toyota to own up to this hidden defect. The electrical systems in these vehicles seem to control every operating aspect of the vehicle and that appears at issue as well.
