Ok, the other day I'm on the freeway going about 60 mph,when the red oil light started to flicker. The faster I went 65-70 mph, it stayed on red. (goes off when I slow down) I checked the oil level and it was normal. Then yesterday again, driving about 60 mph on the freeway, the battery light,brake failure, and parking brake lights came on and flashed a few times. (I just got new brakes 3 days ago) Today when I went to move the car all of the lights I mentioned before were on, except now they just stay on. Any Idea what could be causing this issue?
