Anybody experienced failures of these before? I need to know if it is the controller or the shock iteself that has failed. Any ideas?

Also, anybody know where to get parts for these. Seems very hard to find.

Cheers,

Those systems are very rare and parts are very expensive for them.
Most people end up changing to regular (non-sonar) suspension.
Unless you really love the system and are willing to spend a lot to keep it, just replace with normal struts from internetautomart or wherever and unplug the harness on top of each strut and you should be allright.

 

I thought I replied to this,
As craig said it's more cost effective and easier to swap in the coventional struts than to replace the electric ones with another set of electric ones, not too mention easier.

 

I replaced the Sonar suspension with standard KYB's. Saved about $600.
