Electrical System
Upon starting vehicle, gas gauge and tachometer did not work. Turned ignition off then restarted and gas gauge fluctuated and finally responded, but no response from tachometer. After driving vehicle with air on, stopped at store then started vehicle and all gauges worked. This has happened quite often since it is getting warm. I have read blogs where other owners of the sport model are experiencing the same issue…

On approximately february 28, 2012, the abs/trac control/vsc lights came on and remained lit on my 2003 toyota 4runner. I called the dealership and they said to bring it in right away. They diagnosed the car and came up with "no sensor reading?. It cost me $150 for the diagnostic test. I picked up the car and a few weeks later i brought it back for the same problem. The computer then indicated that there was a…

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…

The vehicle would rev itself up to a high rpm, from a stopped position when i stepped on the gas the vehicle would go in reverse. The dealership eventually replaced the transmission only after the manager borrowed it overnight and experienced it himself, but i have noticed the problem beginning again. Another problem is the radiator leaking and needed to be replaced (i was told it had the wrong kind of antifreeze;…
