AAA Shares Essential Car Prep and Safety Tips for Extreme Heat

“AAA Roadside Assistance responded to millions of calls for service nationwide last year, and many were due to heat-related issues such as battery and tire failures,” said Julian Paredes, AAA Mountain West Group spokesperson. “With proper maintenance, you can beat the heat and avoid costly repairs and breakdowns.” 

WHAT: AAA Mountain West Group is sharing vehicle maintenance and preparation tips to prevent heat-related breakdown, alongside crucial safety steps for stranded motorists during extreme temperatures. 

WHY: In 2025, AAA responded to more than 30 million roadside service calls across the country with blown tires, battery replacements and jump starts being the most common calls.  

AAA technicians say these car components are more vulnerable to heat damage

  • Car batteries. Heat significantly shortens a car battery’s life, reducing it from the typical 3-5 years to as low as 2 years. A struggling engine start, vehicle warning lights, odd smells, or corrosion on the battery terminals are all signs of a failing battery.
  • Tires, belts, hoses. Hot pavement causes tires to bulge, dry out and rot, increasing the risk of blowouts, while belts and hoses can crack. Inspect rubber components for cracks, listen for noises, and monitor tire tread depth. Get hidden components checked by a trusted mechanic.
  • Vehicle fluids. Coolant, engine oil, brake fluid, and transmission fluid are essential for your vehicle’s performance. Summer heat can cause these fluids to boil or evaporate. Keep an eye on your engine temperature gauge and any warning lights. Check beneath your car for leaks.

If you feel the car losing power or see steam, AAA recommends motorists follow these steps:

  • Get Off the Road. Pull as far onto the shoulder as possible. If you can safely coast into a shaded area or nearby parking lot, do so, as it is safer than sitting in the sun. 
  • Signal for Help. Turn on your hazard lights immediately. If you have reflective triangles or flares, place them behind your vehicle safely to warn other drivers.
  • Assess the "Oven" Effect. If the AC is off, a car can reach lethal temperatures in minutes. If you must exit your vehicle to avoid extreme heat, only exit if your surroundings allow for a safe exit away from moving traffic, and find shade nearby. However, it is recommended you stay in your vehicle, with your seatbelt on and the windows cracked to allow airflow. If you see steam, wait at least 20 minutes before opening the hood to check fluid levels, as pressurized coolant can cause severe burns. 
  • Call for Professional Help. Contact AAA Roadside Assistance or a tow service. Wait times often rise due to a higher volume of calls for service during the summer.
