Vvti oil line has large hole all of a sudden, caused very quick loss of all oil in car. I was in motion on the highway, and oil light came on. I was able to get the car pulled over and stopped. If i had been in a worse position, it would have caused engine seizure. There is a limited service campaign on this, my vehicle had it replaced in 2014, and it failed again because they put the same faulty part with rubber…

While putting on the brakes to stop for a traffic light the engine suddenly revved up to 6000 rpm and tried to take off by itself. I pushed the gear shift into neutral and put my left foot on the brake to keep the car from moving. I kicked the accelerator pedal several times until it disengaged. This is the 4th time this has happened. There was not a floor mat involved as there was not one in the car at this time.…

My wife was driving the minivan with both kids in the car after grocery shopping and picking them up from the preschool. While she was driving into the garage she smelled and saw oil fume coming out of the hood. She thought the car was going to catch fire and grabbed the kids and got out of the van as quickly as she can. I got her call and rushed home from work. It turned out there was a sudden failure of a oil…

The vehicle came to a stop at a stop light and the odour of something burning entered the cabin. No lights on the dash appeared and drove to the next parking lot to find a trail of oil behind the vehicle and a pool of oil under the engine. I had the vehicle towed directly to the dealer to find out a 'pin hole' was found in the oil cooler hose. This is not the same hose as the vvti that has been recalled already. The…

Upon exiting the interstate, we began to smell a burning smell and the light for the a/c started flashing and wouldn't turn back on. We drove about a mile thinking that the smell was roadwork, but then we decided to stop and check it under the hood. Once we opened the hood, we were hit with a plume of smoke, and realized there was a pool of oil under the van. We began to look on the internet for causes, where we…

Once the automobile came to a stop my wife pressed the brake a little more in order to put the vehicle in park. At that moment the vehicle accelerated incredible fast, jumped over an 8 inch concrete parking lot divider…

The rubber in the oil cooling line broke down and drained most of the oil from the engine. From looking at the different boards this seems to be a common problem with this hose. Toyota even re-designed the hose with a metal sleeve because of this. *tr

The rubber portion of the oil supply hose for the wt-1 actuator failed resulting in a sudden loss of several quarts of oil. This oil was carried along the undercarriage and sprayed a fine mist of oil on the windshields of the cars behind the van. Luckily this occurred close to home at a low speed. If this was on the highway it could have caused sudden reduced visibility for the drivers behind the vehicle and could…

Van spontaneously began leaking oil. I brought it into the dealer and was told that it was the vvt1 actuator hose. Apparently this was part of a voluntary recall that toyota started in 2010 and i was never notified! I called toyota motor corporation and was told that this was in fact a defective hose but because it was not repaired prior to the 3/31/13 deadline that toyota would not pay for this defective hose to be…

I had a oil hose in my van get a hole. When it happened it spilled oil all over and in my opinion could have started a fire.the hose is connected to a pipe and the hose cannot be replaced. The whole pipe has to be replaced and i replaced mine. My research revealed this is a fairly common problem and that there is a toyota service bulletin for this problem but in the bulletin they claim it's for seepage of oil.…

I was driving down the road and saw smoke rolling out of engine. By the time i pulled over i noticed oil leaking out everywhere. It was the engine oil cooler line and i have since replaced the rubber hose twice and has ruptured two more time since. This is very dangerous. I lost over 12 quarts of oil in the last month.

There was no warning indicator or anything adverse until that moment. Thankfully i live near a mechanic and we were able to leave it there. Apparently this is a known problem at toyota- as the part was on a national…
