2009 Toyota Sienna Owner Comments

Sienna 6-cyl

  • 37,000 miles


I have a 2009 Toyota Sienna with about 37800 miles on the engine. This is a certified pre-owned Toyota and I bought it with approximately 33000 miles on it in November of 2010. At about 37000 I noticed a ticking noise coming from the engine at idle. It starts after the engine warms up; mostly after driving about 15 minutes. I took it to a Toyota dealer for a diagnosis and the dealer stated they heard it and it's only normal engine sound. There is a tsb 0094-09 that addresses the issue. However, my vehicle does not fall within the affected production change effective VIN according to the Toyota dealer. As a matter of fact my Sienna was manufactured about 2000 vehicles after the affected production change effective VIN. I believe the problems related to tsb 0094-09 still exist beyond the affected vins in the tsb. Toyota should really fix these problems. The engine loud ticking noise that is easily noticed is not normal.
