Nissan Versa recurring engine light issue after dealer-installed coils on Nissan Versa

Some Nissan Versa owners report experiencing recurring engine light issues after dealer-installed coils, which may indicate serious misfire problems that can lead to raw fuel entering the exhaust system and damaging the catalytic converter. A common concern noted is a failed valve cover gasket that allows engine oil to contaminate the coil packs, resulting in misfires. Additionally, some owners find that worn-out spark plugs contribute to these misfire issues, emphasizing the importance of timely replacements. Even with recent coil replacements, some owners still encounter problems due to faulty ignition coils, highlighting the need for a thorough reevaluation by the dealer to ensure all ignition system components are functioning properly.
