The vehicle stability control is much too sensitive. As a turn is taken at speed the vehicle electronics take over and change the trajectory. For example, if turning on a curve to the right, if it senses a tire rotation discrepancy it steers the vehicle into oncoming traffic. This is reproducible demonstrating that this is the way that it is designed and not an unusual occurrence. Changing tires helps somewhat but does not mitigate it entirely. I have brought the vehicle in many times to Toyota under warranty and nothing is found and nothing is done to improve it. Online help directly with Toyota likewise has not lead to any improvement. This is a safety issue for many reasons including directing the vehicle into traffic and it is very disconcerting to suddenly have the vehicle take control of the steering when negotiating a turn, particularly on narrow roads or sharp turns. I even had Toyota service advisor in the vehicle when it happened. This is an ongoing issue.

Vehicle randomly and suddenly revs itself both from a stopped position and while driving. When driving downhill and I take my foot off the gas the vehicle will continue to rev itself around 3000 RPM then when I start to travel uphill it will down shift to about 1500 RPM. This seems backwards. Tapping brakes does not cause it to downshift as needed, does not seem right to apply brakes and vehicle continues to rev itself higher nor does it seem right to take foot completely off the gas pedal and the vehicle continues to rev up. The only way to get it to idle is to apply pressure to the gas pedal and speed up which is dangerous when already going downhill. When travelling in a parking lot it rev itself up and will jump forward. From a stopped position such as in my driveway or at a stoplight I will press the gas and it will not go into drive but it will rev up to about 3500. None of these issues can be duplicated by the dealership of course. At one point they finally changed out some type of component in shift mechanism and that worked for about a week then the problem started again. There is never a code indicating there is anything wrong although the trac light will randomly come on and not turn off. I have been driving for 30 years and know when a car is not driving properly. This is my 2D 4 runner. First was an '03 and had similar issues but since was less than a year old I finally convinced the dealership to replace the transmission at Toyota cost. This one was purchased used and has more miles on it but it seems to be the same problems as my original. The only way I have been able to get dealership to believe me is to ask the service manager to drive my vehicle for several days then they are like oh I see what you mean. Another incident was on a snow packed road. Travelling 10mph when the vehicle downshifted I lost control.

After starting my vehicle the ABS and stability control lights came on and never went off. My anti lock braking and traction control do not work now. I just found out Toyota is recalling several models from 2012 and 2013 for the same problem and my vehicle is not listed. Do I have to have an accident or injury before it is added to the recall"?" sounds like a lawsuit to me. I have a 2010 4runner.

22dec12 49F entered corner at 50mph, roads slightly wet. 4runner decided the car was slipping and the panic beeps went off and the car applied brakes. Unfortunately the computer straightened the car out and pointed it off the road. It took all my strength to turn the car back into the corner and finally the computer stopped the panic. After this I was unable to turn off the traction control via the enable/disable button until I had turned off the vehicle. I was following a car into the corner and that car navigated the corner fine. Also, since owning this vehicle, 10 times it has assumed I was panic braking. Literally, the 4runner slams on the brakes and brings the vehicle to a stop. Luckily there has been no one behind me during these events. In the winter of 2011, the 4runner lost control on an icy road at fairly low speed. I couldn't do anything because the computer was trying to get control back. I suspect the computer got confused because I could have totally gotten control back. The traction control is never really off. You can turn it off, but it will kick back on when it thinks you are no longer in control of the vehicle.

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.
