Maintance 2014 ford focus

Sounds like a front end alignment is in order, rotation of the tires, if not new tires if those are original since they don't last as long as brand name aftermarket tires. Serpentine belt could go a little longer but good idea to replace, Inspect pulleys and idlers. Check wear on breaks, Check all fluid levels & hoses, just a going over. Trany filter and oil change would be a bad idea also. Keep the engine oil changed of course.

Check/replace air filter. fuel filter, and such.
