The Headlights pulse and fan blower pulses with changes in engine rpm. I measured the voltage change and I have a 1.5 volt drop that takes over one second to recover. There was a service bulletin to address the pulsing headlights by installing new computer software. I had it performed and it reduced the headlight pulsing some. I took the car back later and the shop rushed me in and out and told me it was normal. I've just been living with it, but it doesn't instill a lot of confidence in the car and its electrical system.

Clunking in suspension along with some sketchy handling prompted me to pay someone to change the bushings (it looks way too hard to attempt). Handling is restored to normal and there is no more clunking. A creak remains while driving over big bumps, and there is a slight knock while driving on small ones. I have yet to determine if the noise is coming from the end links or the shock absorber assembly, which was a pre-manufactured unit that I don't love. The sound is clearly coming from the front right wheel well, which is why I do not suspect the bushings.
