Electrical system

16 reports1 crash1 fire
“When driving the steering will feel loose and the car sway left and right but the steering wheel isn't moving. Feels like the front wheels are going to all of a sudden shoot left or right and loose control.. I had a 2001 crown Victoria and there was a recall on the steering shaft and I got that fixed. it was doing the exact thing my mercury is doing now.. and also my electrical is freaking out.. turn signals flash very fast here and there.. speedometer will freak out and then not work.... I'm mostly concerned about the steering because it happened in my crown victoria.”
