Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2001 Toyota 4Runner Owner Comments

problem #5

4Runner 4-cyl

  • 132,500 miles


After I my mechanic replaced the catalytic converter for $1500, this problem began. The vehicle began to buck (jerk violently) as I was accelerating to 45 mph. It always happens at about 20 mph as I try to accelerate to 30, 35 or 40 mph. The engine revs up to 3 of 4K before the transmissions engages forcefully. This has been going on for now 3 months.

I initially contacted magic auto center and was dealing with [xxx] regarding a 2001 Toyota Land Rover that I was interested in. [xxx] told me he could give me $1000 for my trade and use that for my down payment. When I called the dealership on Friday the 29th, I spoke with [xxx]. [xxx] informed me that the vehicle I was interested in had been sold but they had a 2001 Toyota 4runner priced similarly. At that point, I submitted all of my credit information by E-mail to [xxx] address above. Anthony contacted me back and said that the owner wanted $1000 cash and would give me $500 for my trade. I agreed to that, even though it would cause me a financial hardship because I needed a more reliable vehicle than what I had. I arrived at the dealership a bit before 8pm on the 29th and advised them that I was in a hurry as I needed to pick my daughter up by 9pm. When I arrived, I was then asked to provide $750 cash, $250 on 11/2/2010 and an additional $500 on 11/18/2010, plus my trade. I had specifically asked that everything be in order before my arrival since they are located far from my residence. I was given the run around until almost 8:30 pm. I did not test drive the car (my fault) because I was so rushed, but was assured that it was in excellent running condition by both [xxx] and[xxx]. I signed the paperwork, provided them with a check for $500 dated 11/18/2010 and agreed that I would bring $250 on 11/2/2010. I transferred my belongings from my trade to the Toyota 4runner, with my son\S help, took the 4runner, my son, and our dogs and headed for the freeway. We got on the 170 South, to the 101 South, and the gas light came on...we got off the freeway and put gas in the vehicle, it was already after 9 at this point. We got back on the freeway and inadvertently got on the 10 freeway West, at that point a loud pop came from under the hood, followed by a huge puff of steam, the engine overheated.

The contact owns a 2001 Toyota 4runner. While driving approximately 25 mph, she noticed a noise and the vehicle would not accelerate. The vehicle was towed to the dealer who stated that the motor was the root of the failure; however, they didn┐T provide an explanation why the failure occurred. The dealer offered a $5,000 rebuilt motor at the owners expense. The vehicle has not been repaired. The manufacturer was not notified. The VIN was unavailable. The current and failure mileages were approximately 67,000.

[xxx] just driving along a loud noise was followed by excessive vibration and a connecting rod became disconnected from the crankshaft for no explainable reason, no crash occurred but easily could have as the oil pan was punctured and oil spilled out on the highway. I have discovered five out of warranty cases identical to mine in 5vz-fe engines where just driving along a loud noise was followed by excessive vibration and a connecting rod became disconnected from the crankshaft for no explainable reason and in each case no other service issue was identified: 1999 4runner, failed at 78,000 miles in 2003 1999 4runner, failed at 98,000 miles in 2006 2000 4runner, failed at 78,000 miles in 2006 2001 4runner, failed at 103,000 miles in 2008 2001 Tacoma, failed at 92,000 miles in 2007.
