Any help is appreciated. Currently experiencing two problems.

1. Brake lights go on and won't turn off. Guessing the brake switch? Any other ideas?

2. Has been happening for about a month just never took it in but At startup I get a loud squeal or high pitched whistle. Just once and it goes away. Also have smoke from exhaust, nothing sounds crazy but that just started as well.

Again thanks to anyone with knowledge of past issues.

 

check the belt on squeal on startup, and check the brake pedal switch under the dash
