🔥 Hot Weather Car Trouble? Here's What You Need to Know
Share
When summer heat kicks in, your car feels it too — especially in cities like Memphis and the Mid-South, where temps climb fast. While you’re staying cool, don’t forget your vehicle needs a little TLC to handle the heat. 🧊🚗
Here are the top car problems caused by hot weather, and how you can avoid getting stranded or stuck with a big repair bill.
1. 🔋 Battery Failure
Hot weather is actually harder on car batteries than cold. Heat causes fluid inside the battery to evaporate, shortening its life.
Tip: Have your battery tested (especially if it’s 2+ years old), and clean off corrosion on terminals.
2. 🌡️ Overheating Engine
Your engine needs to stay cool — and in summer, it’s under more stress. Low coolant, busted fans, or old hoses can lead to overheating fast.
Tip: Check your coolant level regularly and look out for leaks, dashboard warning lights, or rising temperature gauges.
3. 💥 Tire Blowouts
Tires expand when it’s hot. If they’re worn down or under-inflated, that pressure build-up can lead to a blowout — especially at high speeds.
Tip: Check tire pressure monthly and inspect tread. Don’t wait until winter to replace worn tires — summer heat does damage too.
4. 🧊 Weak Air Conditioning
Nothing feels worse than driving in 100° weather with no AC. Over time, components wear out or refrigerant leaks.
Tip: Run your AC early in the season to test it. If it's blowing warm or weak air, bring it in before peak summer.
5. 🧴 Low or Burnt-Out Fluids
Heat causes fluids to break down faster — including oil, brake fluid, transmission fluid, and coolant.
Tip: Top off fluids regularly and ask for a fluid check at your next oil change.
6. 🛠️ Sensor or Electrical Glitches
Today’s vehicles have sensors, cameras, and computers that don’t always like the heat. Expect weird warning lights or temporarily non-working features.
Tip: Let the car cool down if electronics act up — and check for blown fuses or frayed wiring if the issue sticks around.
7. 🪑 Interior Damage
Sun and heat can crack dashboards, fade upholstery, and warp panels.
Tip: Use a windshield sunshade, crack the windows, and park in the shade when possible.
8. ⛽ Fuel Issues (for Older Cars)
In older models, extreme heat can cause fuel to evaporate or create vapor lock, making it hard to start the engine.
Tip: Keep your gas tank at least ¼ full and make sure your gas cap is tight.
