Why Your Check Engine Light Might Come On More in Summer

You’re driving with the A/C on, the sun is blazing, and suddenly—you see the check engine light. 

It’s a common North Texas summer issue, and it doesn’t always mean something serious. But it does mean your vehicle needs attention.

Heat can put extra stress on your engine, sensors, and emissions system. A loose gas cap, a misfiring sensor, or even an overheating engine can trigger the light. Sometimes, it’s just a small problem that’s easy to fix. Other times, it could be the start of something bigger.

Ignoring the light can lead to more damage, especially if you’re planning a summer road trip or if your teen is using the vehicle. It’s best to get testing and analysis done right away so we can find the cause and get it fixed before it becomes a major repair.

Your vehicle should not make a loud clunk each time you hit a bump. If you hear a clunking noise over bumps, there may be a worn or loose part in the suspension or steering system.
