How often should an ignition coil need replacing - my Elantra only has 25K miles?

Ignition coils typically last between 60,000 to 100,000 miles, so at 25,000 miles, your Elantra's coils should still be in good condition. They may need replacement sooner if you experience symptoms like misfiring, rough idling, or difficulty starting the engine. It's always a good idea to consult your owner's manual or a trusted mechanic for specific maintenance recommendations. Regular inspections can help identify any potential issues before they become serious.
