As an unprecedented heatwave settles over the region, local mechanics and transportation experts are issuing an urgent advisory to motorists: extreme temperatures are wreaking havoc on vehicle reliability, leading to a surge in roadside breakdowns across the county. With temperatures consistently hitting triple digits, the stress placed on aging cooling systems, tires, and electrical components has reached a critical threshold.
“We are seeing a massive uptick in calls for assistance, particularly involving overheated engines and battery failures,” said Marcus Thorne, a lead technician at a regional automotive repair hub. “When the ambient temperature climbs this high, a car’s cooling system has to work twice as hard just to maintain standard operating levels. If there is even a minor vulnerability in your hoses, radiator, or coolant levels, the heat will expose it very quickly.”
Public safety officials are reminding residents that roadside emergencies in extreme heat pose a significant health risk. Authorities are urging drivers to conduct “heat-safety” checks before embarking on any travel, even short commutes. Experts recommend a three-point inspection: checking coolant levels, inspecting belts and hoses for signs of dry rot or cracking, and monitoring tire pressure.
“Many drivers forget that high road temperatures cause tires to expand, which can lead to blowouts if the tires were already worn or improperly inflated,” Thorne added. “It’s a perfect storm of mechanical stressors.”
In addition to mechanical maintenance, officials are emphasizing the importance of vehicle preparedness for those who do find themselves stranded. Experts suggest keeping an “emergency heat kit” in the trunk. This kit should include at least one gallon of water per person, a portable phone charger, reflective sunshades, and non-perishable snacks. Most importantly, if a vehicle does break down, occupants should attempt to stay in the shade or, if safe, remain inside the vehicle with the windows cracked and air conditioning running if the engine permits. However, if the engine is the cause of the breakdown, occupants should exit the vehicle and seek immediate shade away from the flow of traffic.
Local law enforcement has noted that traffic congestion often exacerbates these issues, as idling in stop-and-go traffic prevents sufficient airflow across the radiator. Motorists are encouraged to avoid unnecessary travel during the peak heat hours of 12:00 p.m. to 6:00 p.m. whenever possible.
As the heat advisory remains in effect, the message from repair shops is clear: preventative maintenance is no longer optional—it is a necessity to avoid being left stranded in dangerous conditions. For those unsure of their vehicle’s condition, a quick professional inspection is a small price to pay to avoid the dangers of a mid-highway breakdown in the blistering summer sun.
