There is excessive rust on the underbody of my 2003 4runner. It has just 165,000 miles and the frame is extremely rusted. Being only 15 years old i find this to be very sad and unreasonable. The car should be able to last 20-30 years and 300,000 miles. The car has been regularly washed and driven in pennsylvania, illinois, ohio, new york. If there was additional treatment required for the frame it should have been…

Vehicle has a low gear sound which began when vehicle was relatively new as i travelled down slight grades. I never complained because that was the only time it seemed abnormal and there are only a very places in my town where the hill was steep enough to cause it. Plus i assumed it was related to the trac braking system and might be normal. Last weekend on a 5 hour trip each way the problem began to manifest itself…

My 2003 toyota had emissions issues in that all four oxygen sensors would fail quickly. It took me two years and lots of money later to determine that the cause of this is because transmission fluid is wicking its way through the transmission solenoid harness all the way to the ecu and once there because of the way the ecu is mounted gets into all of the other wiring harnesses of just about every other sensor. I…

From a completely stopped position, letting off the gas and allowing the truck to idle forward results in a klunk noise whether you accelerate or not. As i have read, it is a problem within the drivetrain. I took the truck to toyota to have it looked at. They say it is because the rear needs to be lubed with every oil change and was completely dry. They lubed it up and said the problem should improve with time. The…

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;…
