Summer in Maryland means road trips, beach days, and longer drives in hot weather. But rising temperatures and increased travel also make summer one of the busiest seasons for vehicle breakdowns. Heat puts extra strain on engines, batteries, tires, and cooling systems—often exposing problems that weren’t noticeable in cooler months.
At Catlett’s Auto Service & Towing in Davidsonville, MD, we see a spike in roadside assistance calls every summer. The good news? Most summer breakdowns are preventable with the right maintenance and preparation.
Here are the top causes of summer breakdowns—and how you can avoid getting stranded.
1. Engine Overheating
Overheating is one of the most common summer breakdown causes. High temperatures combined with traffic congestion can push cooling systems to their limits.
Common causes include:
- Low coolant levels
- Radiator leaks
- Faulty thermostats
- Failing water pumps
- Broken cooling fans
How to prevent it:
Have your cooling system inspected before summer travel. Check coolant levels regularly and never ignore rising temperature gauges.
2. Battery Failure
Many drivers think cold weather kills batteries—but summer heat is actually harder on them. Heat accelerates internal corrosion and fluid evaporation inside the battery.
Signs of a weak battery:
- Slow engine cranking
- Electrical issues
- Dashboard battery warning light
How to prevent it:
Have your battery tested before peak summer heat. If it’s more than 3–4 years old, consider replacing it proactively.
3. Tire Blowouts
Hot pavement increases tire pressure and weakens already worn tires. Combine that with underinflation or long highway drives, and the risk of blowouts rises significantly.
Common causes:
- Underinflated tires
- Worn tread
- Old or dry-rotted rubber
- Overloaded vehicles
How to prevent it:
Check tire pressure monthly and before long trips. Rotate tires regularly and inspect tread depth.
4. Air Conditioning System Failure
Nothing makes a summer drive more miserable than losing A/C in traffic. Cooling systems work overtime in high heat, and weak components often fail when pushed.
Signs of A/C trouble:
- Warm air blowing from vents
- Weak airflow
- Strange smells
- Unusual noises
How to prevent it:
Schedule an A/C performance check before summer travel season begins.
5. Fuel System Issues
Heat can affect fuel systems, especially if your tank runs low frequently. Vapor lock and clogged filters are more common during extreme temperatures.
How to prevent it:
Keep your fuel tank at least a quarter full and replace fuel filters as recommended.
6. Worn Belts and Hoses
Rubber components deteriorate over time. Summer heat accelerates cracking and splitting, especially if winter already caused wear.
Look for:
- Cracked belts
- Bulging hoses
- Leaks under the hood
How to prevent it:
Routine inspections catch these issues before they fail on the highway.
7. Ignoring Routine Maintenance
The biggest cause of summer breakdowns? Skipping regular maintenance.
Oil changes, fluid checks, brake inspections, and tire rotations all play a role in preventing failures during high-demand driving months.
At Catlett’s Auto Service & Towing, we emphasize preventive care because it saves drivers money—and prevents emergency towing situations.
