The transmission shift cable broke during parking. Although the transmission shift lever was moved to the park position, the transmission was not placed in park. The first observation was the vehicle started to roll when the driver was loading the purchases at a store. The parking brake was then applied. Then the vehicle engine could not be started, regardless of where the shift lever was positioned. The vehicle was towed to an independent auto service provider. The provider identified the problem as the transmission still in the reverse position and replaced a $10 bushing on the transmission cable with a labor charge of $510.

I attempted to put my van in park today after driving to a restaurant for lunch. The shift lever will go to any position but the dash display only responds to D or 4. when I put the lever in park and took my foot off the brake pedal, the van continued going forward. It will not go to park or even neutral. I put the car in a safe parking spot, put on the emergency brake and shut the engine off. That is where it still is. I haven't tried to restart it or drive it since.

Detroit axle, in Michigan, is selling defective struts, straight out of the junkyard, and rack and pinion steering and many other suspension parts, advertised as new, by just placing a coat of paint in them. They offer a warranty of one year in the products, but the consumer must pay for the removal and installation of the part. I played their game for three times and I foolishly paid 3 times for the strut installation, plus other damages the faulty struts caused me. The faulty struts caused my frame to loosen, my horizontal drive shaft to damage, and rack and pinion steering, that detroit axle sold. Well, my vehicle shakes violently at between 45-55 miles per hour, thus having to pull to the side of the road. I managed to drive to a mechanic through back roads at low speeds. The defective rack and pinion steering and the defective, sold as new parts, and advertised as new parts failed in three occasions ane damaging my other parts of the vehicle. It cost me over $3000 to replace those parts plus the money that I gave to detroit axle, with the collusion of ebay selling his products. Once the parts are received, within 60 days, he closes the feedback on his page, thus not letting the suspecting public complain against his junkyard of defective parts. Ebay protects him. I still have to replace my Michelin new tires for more expense and the third pair of struts are still on the vehicle, in which I still have to replace for a third time!

Shift lever assembly may allow rollaway 13V429000 my Sienna had the above recall work completed. My little daughter bumped the gear shift and knocked it out park and the car rolled away. The Sienna was in park, the key was out of the ignition and the brake pedal was not touched. My concern is that fix provided for the recall did not actually correct problem completely. If you have a Sienna for the effected years and have had the above recall work completed your vehicle may still roll away. To test park on a flat surface apply emergency brake grasp gear shift apply pressure to move it toward reverse while jiggling the gear shift up and down - do not put your foot on the brake while doing this. If gear shift stays in park you are good. If it falls into reverse your car is now in neutral and can roll away put foot on brake and put the car in park.

That was around 2012 new year time when I, my wife and my kid visited our friend at atlanta, ga. We drove our van on interstate highway I-75, in the middle of our trip, our van started shaking vigorously. I felt that was from engine, it forced me to stop on the side of I-75. After a while we restarted our van, we could only drive for < 65 miles/hour. Any acceleration resulted in vigorous shaking. After we came home I drove my van to an auto service center, and was checked. It turned out that 3 ignition coils, spark plugs, and manifold gasket had to be replaced. Yesterday (9/10/2015) the same problem happened again.

T-sb-0047-10 from safercar.gov "some vehicles equipped with 2gr-fe/fxe engine. The rubber portion of the oil supply hose for vvt-I actuator may degrade over time. This condition may cause oil to leak from the vvt-I oil hose producing abnormal engine noise and the oil pressure light to illuminate " this tsb affects Toyota vehicles going back to at least 2008-present. This is a major issue, and I feel this should be handled as a recall instead of a tsb due to the severity of the issue if/when the pipe breaks. I recently elected to have my vehicle repaired on my own just so I wouldn't have to worry about this issue happening to me or my wife, and thus blowing up my Sienna's engine causing thousands of dollars in damages. Seems pretty bad that a recall can be issued for floor mats and accelerator issues, but no recall is issued for this issue which can drain the oil from your engine in a minute, blow up your engine, and then possibly wreck your vehicle. Consumer's engines are now being destroyed, and this is showing up in different online forums. I feel that the NHTSA needs to force Toyota to replace all of the defective engine oil cooler pipes with the newer metal ones that the tsb addresses. They should also be forced to reimburse all costs to those individuals that either needed to have the repair done, or decided to preventatively have the repair done on their own before those pipes burst on their own. Toyota has told me that my vehicle was not affected by their limited service campaign csc-10033553-6074 but my car has seepage from the rubber portion of the hose that was diagnosed by grapevine Toyota dealership yesterday. Very sad situation that such a dangerous condition exists in so many Toyota vehicles with the V-6 (2gr-fe) engine. Please help!!!

I was dropping my kids of to school in the morning. I stop by at my friend's apt to pick her up with her baby. This is my daily routine. So on the day of the incident, I did the same thing, parked my van, got out, and went to the apartment' S exit door from where my friend was coming. My children were seated in the car and I was picking up the baby from my friend when both of us heard my eldest son aged 10, screaming that "the car is moving mama", and in panic he opened his door and tried to get off his seat belt and was trying to jump. I saw the van rolling back, I put the baby on the grass and rushed to help my kids in the moving van that was rolling backwards downhill. First I pushed my son in as his leg was caught in the seat belt and he couldn't jump forwards and then I moved around the back of the van, hit my knee on the bumper and my friend came from the front, she opened the door and I was able to put the handbrakes on. But in doing so after bumping hard on my right knee from the moving car, and when I applied the brakes, I sat on the ground and hit my knee again. The car stopped and I tried to calm myself because there were 4 kids inside when the van was rolling away and 3 of them were small, so they were crying. My friend calmed me and we set off. My knee was heavily bruised and aching. I came home and took painkillers and couldn't get any xrays done because I didn't have any medical insurance. To this day once or twice a week, I use painkillers for my knee which was perfect before. My kids were safe and nothing major happened which could have, but we all went through a very panicky and terrible experience which I hope never happens again. If the van wouldn't have stopped in time, my children could have been badly injured.

While driving on inter-state I-10 West bound close to 183 marker, at 65 mph, the RPM shot to 7000 and car started to slow down. The car stopped with transmission failure. It was 2200 hours with my family of 4 kids and wife on board. To replace the transmission (used one 90000 miles) Toyota legacy charged me 3500$. its a lot of money. Additionally, you cannot trust Toyota brand for such poor workmanship where power train is prone to failures on 5 years old vehicles.
