My about 2 years ago my 2011 Rav4 6 cylinder suddenly had the check engine, traction control and AWD lights come on for no reason. This also caused the cruise control to not work. After a few days everything returned to normal. A few weeks ago the same thing happened. I pulled the codes and received codes P0037, P0138, & P0607. I cleared the codes but they lights went on and the codes returned after driving a few miles. Other than the cruise control the car drives fine. Could this be some type of computer glitch?
