I just traded my 2000 Tacoma for a 2013 prerunner 2.7 I'm new to the site and had a few questions about it I couldn't find searching previous threads. When I shut it down a noise ( like an electric motor) winds downs for about 1 second? Anyone have an idea what it's from? I also tried the turning radius in a wet parking lot with the tire turned all the way. Without using any gas I could hear one tire slip a few times briefly. Is this normal with the limited slip and traction control? Couldn't find answers in the manual.
