2010 Toyota Sienna Owner Comments

problem #4

Apr 152015


  • 69,000 miles


Both rear shocks failed and started while driving (in motion) in city traffic. Vehicle had 69,000 miles at the time. Purchased new in 11/2009. Vehicle is not used tow or haul heavy loads. The vehicle is driven in Maine. The Toyota dealership performs all repairs. Very expensive repair. The dealership noted no visible or obvious reason for 2 rear shock failures at such low mileage.

Suspension systems specifically shocks and struts are wearing out quickly. Divided opinion between many local mechanics on this, some suspect it is caused due to wear and tear while others think it could be due to possible manufacturing issues specifically for running it on a full load - 8 passenger vs 7 passenger configuration)

Sienna 6-cyl

  • 80,000 miles
My local garage discovered that a suspension coil spring in my 2010 Sienna is broken. I have discovered by searching the internet that this is fairly common in Toyota Sienna models (I saw 2007, 2008 and 2009 models reported to have this problem, in my very brief internet search). This is a family car, and has seen only normal highway driving, no heavy loads and certainly nothing that would normally break a spring. I have discussed this with both the local Toyota dealership's service manager, as well as the corporate Toyota "customer experience" representative. I have explained that a broken coil suspension spring could result in a slashed tire sidewall and associated blowout; a slashed brake hydraulic line and associated loss of braking ability; erratic suspension movement and associated loss of control of the vehicle at high speed. I have been told by Toyota that there is no recall nor repair assistance for this problem.

Sienna 6-cyl

  • 76,200 miles
I took my 2010 Sienna in for a 80000 mile service, was told that the boots around steering rack was in bad shape. I was told that the steering needed to be replaces and the power steering unit would flushing. I had experienced no steering problems with my car. The car less than 77000 miles. The is no evidence of oil leakage. Is this typical for replacing the steering rack at $1400?
