Car had unexplained acceleration. Car had solenoid recall repair. Car would surge forward slightly until accident caused it to go out of control. Also, takata recall. Car was filled with air bag material and side air bags caused almost fatal injury to my wife and severe injury to my son.

I was driving my Sienna on a 2 lane town road and without warning smelled smoke. As I was pulling over cars in the oncoming lane were honking at me as they saw the fire underneath where the engine is. When I pulled over smoke entered into the car. I stepped out, heard a pop, and now the entire front of the car was full on fire. The fire department arrived on scene quickly and extinguished the fire. I filed an incident report with Toyota. I received a call from a man saying he was hired by Toyota to investigate the fire and report back to them. To date, I have received zero communication from anyone at Toyota regarding this serious matter.

I had a catastrophic oil leak all over my driveway and garage. Reseached history of this type and found it was it was a rubber hose associated with oil transfer (also called the V V T 1 actuator hose. A voluntary recall on this part ended in 2013. I will have it fixed by a local car repair shop but if this is a known part failure for years, why would Toyota not make a mandatory recall of this faulty part? my 2009 Toyota Sienna which I just purchased 2 months ago will now have a major car repair.

The oil cooling hose popped while driving car. Apparently there was a recall/service bulletin for this issue involving other Toyota and Lexus vehicles. For some reason there was none issued for this vehicle. Now there is engine damage. Toyota dropped the ball on this one. They need to be held liable for the damage.

Takata recall ! I was driving Toyota Sienna on local street in boca raton when car had unexplained acceleration. Car struck a tree which caused the air bags to react. I had airbags stuffing in my lungs with contusion and in my intestines. My son had a bad contusion on right side from side airbag. My wife had to spend 17 days in a hospital because contusion on lungs and multiple bones. The force not her out of her seat on floor. Her seat belt cut into her abdomen. She almost died from injuries and incompetent medical care. My daughter was saved from severe injury because the side airbag did not function. This was a terrible holiday gift.

While driving down a very steep narrow unpaved drive the engine stopped. All lights on the dash remained on battery light was on. Steering was very difficult and the breaks were stiff. When I came to a stop I restarted the engine.

The car had an alignment problem after 5000 miles. Firestone always aligned the wheels but 1 went through 3 sets of tires. The car would speed up the last couple of months after I took my foot off the gas pedal. The brakes seemed to work but they just did not seem right. I noticed the day after I drove the rav4 the difference form the Sienna. The rave 4 also jerks sometimes when I step on the gas pedal.

2009 Toyota Sienna. Consumer writes in regards to vehicle fire the consumer's insurance company determined that oil leaked from a faulty valve and seal in the manifold cover. However, Toyota provided a different explanation as to how the vehicle caught on fire. They stated the fire was caused by spilled oil and overfilling of oil. Toyota stated they have a photo of the dip stick proving that the oil was overfilled, but refused to provide the picture.
