Check tire balance or struts.

For daily driving, you should definitely leave the it in the 2x mode. Driving on dry surfaces in 4x can damage the drivetrain. The only time you should use 4x is when the road conditions are poor, and slippery.

Look for a failing Crank sensor and/or the cam position sensor. A diagnostic test will tell you for sure.

The Starter Inhibiter Relay is usually located behind the fuse panel under the dashboard. I presume your QX4 won't start or is having a no-crank condition?

Have the exhaust flow tested for a clogged catalytic converter, and have the fuel injectors bench flowed and cleaned.
