hi i own a 03 vibe standard and the abs light is on and the brake light comes on at random times does anyone know why thanks

its not gt and its fwd

ive searched all over the internet thats why i i came to this forum

I have a 2003 pontiac vibe and in when i shift to 3rd gear it grinds, but if i slowly ease it in third it doesnt grind. I am curious what is wrong and what parts do i need to fix it thanks
