The head gasket that was repaired failed and the radiator system also failed. Im not sure if these issues are dealer related or manufacture related as i spoke to the previous owner and they stated they had the vehicle serviced at a manufacturer prior to doing a trade in with the dealer

Check engine light, vsc light and trac off light on and off light intermittent. At any time the light goes on and off. It is nerve breaking knowing that the warning light and the problem can not be fixed by toyota. I have my toyota sienna 2008 and it have a very low miles due to lights safety reasons that can not be solved by toyota. Every time we complain, we were always told that bring the car in when the light goes on. The problem is when the light goes on it will be off when we get to the dealership. We noticed when the car reached approximately 98,000 miles. The cause of the on and off lights are unknown.

While driving with my autistic children the check engine light, the vsc light and the trac off light all came on and the wheels locked up on the right side and through the van into a ditch. This is very dangerous since this vehicle was made for families. I am now keeping a log and I do plan on retaining an attorney as no one has addressed this issue as a safety hazard.

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 hose connector. In 2010 they actually released same engine with an all metal oil hose, but thats not what they replaced it with on the technical service campaign.

My 2008 toyota sienna began to create a smoke screen impairing me from having a clear visual of the road. I had to immediately pull to the side of the freeway and check if my vehicle was on fire. Once I inspected the outside and open the hood to make sure nothing was on fire I notice a puddle of oil under the vehicle an upon further look my engine motor oil cooling hose had burst, spraying the motor and everything inside with motor oil. This was the 3rd time this vehicle has done the same problem.
