Since 2013 I have been experiencing electrical issues with my car. First in 2013 it was very sporadic. The bluetooth and radio would not turn on approximately once every 2 to 4 months so I would turn off the car and restart it and it would connect. This year in January 2016 the fan was not blowing and there was not heat in the vehicle. I turn the car of and restarted it and the fan began to blow immediately. Last week my steering wheel felt like it was not going to complete my left turn and got really tight. Yesterday as I was driving my accelerator and brake began to feel very tight as if they were both getting stiff and the suspension started getting very tight then as I was backing into a parking space my backup camera started flickering like poltergeist. I took the vehicle to check it I needed a battery or a new alternator and they said nope. My battery, my alternator and started are all good. I have been two different places and they told me that I have an electrical issue that has just gone bad over time. I tried to have someone look into it in 2013, but anytime someone held onto the vehicle nothing happened. I just spoke to another mechanic and they said I may need a new pcm. I am not sure what the problem is but would like to get to the bottom of it.
