The vehicle's gas tank won't hold much and clicks as if full. Also, when on uneven pavement or ground, the ⛽ gas warning light comes on, even after gas was just put in. In addition, at times I smell a "burning electrical" smell and the headlights go out, the brights fail to "click" on or goes off by itself. The turn signal lights have to be turned manually to blink. All turn signal lights have been replaced multiple times and this does not fix the problem. The back turn signals work and light up, but not the front & blink at a faster rate. Even one side headlight engagement was replaced and the problems still exist.
