| Description of the problem | 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. |
