• Unusual noises (grinding, clunking, or whining): identify source early to avoid cascading wear on suspension, drivetrain, or brakes.
• Sudden loss of braking performance or pull to one side: inspect brakes and tires immediately.
• Electrical gremlins (display issues, Bluetooth dropouts, screen freezes): software updates or head unit checks can fix most, but root causes should be diagnosed if persistent.

MAINTENANCE PLAN TO PREVENT PROBLEMS (WHEN TO SERVICE)

• Oil and filter: every 5,000–7,500 miles with synthetic oil (as per owner’s manual for your engine).
• Tire rotation and alignment: every 5,000–7,500 miles or with tire replacement; check tire tread depth regularly.
