I own a 2012 Honda Accord with approximately 116,000 miles. Recently, I've noticed an increase in engine vibration while idling, like at red lights or when parked. There's no check engine light, but the engine feels rougher. What could be causing this, and how should I address it?

Hi there, Susan! Engine vibration in your Honda Accord could be due to several reasons. Here's a breakdown of potential causes and solutions:
  1. Engine Mounts: These mounts can deteriorate over time. The rubber in the mounts hardens and may not be visually noticeable. Replacing the front engine mount and transmission mount is advisable.
  2. Regular Maintenance: If your car hasn’t had its 100k mile tune-up, it's time to consider it. This includes checking the spark plugs, water pump, tensioners, and timing belt (for V6 engines). Valve adjustments can also smooth out engine performance.
  3. Coil Packs: Occasionally, coil packs can fail, leading to vibration and rough running. Though not a common issue, it's worth inspecting.
  4. Air Conditioning Load: Running the A/C places extra load on the engine. This is normal and might cause additional vibration, especially when the compressor cycles on and off.
  5. Seek Professional Advice: If you’re unsure, it’s always best to consult a professional mechanic. If they find no fault codes, insist on checking the engine mounts and other potential mechanical issues.
Remember, some vibration is normal, but excessive shaking can indicate a problem. It's better to address these issues early to avoid more significant problems down the line. Stay safe and happy driving! Zack - Motor Verso Mechanics Team
