I used to fight the car to keep the SoC from getting completely drained, and I thought the IMA battery was just going bad. Turns out the clogged cat was causing the car to work way, way to hard to move, therefore using more assist. Since I fixed the exhaust, I rarely ever drop below 18/20 SoC bars.

How did you discover all of these?
