(Tekonsha 90195 P3) worked great until July 2013 then would not turn on. I called Tekonsha and relayed the problem. They said, send it in and the will look at free of charge. Long story short they sent me a new tekonsha 90195 P3 free of charge. This brake controller has a lifetime warranty.
When installing a P-3 in a 2011 Outback I had issues with connecting to the four wire brake switch connector. Gave them a call, they had the wiring diagrams for the car and they told me which wire to connect the brake wire to. Great service.
