#BuickRepair,

Buick vehicles are known for their reliability, comfort, and performance. Regular maintenance is essential to ensure your Buick continues to perform at its best. Here are key service intervals and maintenance tasks for keeping your Buick in top condition.

The Buick trouble code P2312 typically indicates an issue with the ignition coil secondary circuit on cylinder 3. This code suggests that there may be a malfunction or failure in the ignition system, particularly affecting cylinder 3. The ignition coil is responsible for generating the high voltage needed to ignite the air-fuel mixture in the combustion chamber, and any disruption in its operation can lead to misfires or poor engine performance.
