UK Heatwave Prompts Warning Over Dangerous Car Items
As the UK experiences its third heatwave of the summer, with temperatures forecast to reach 35°C in some regions this week, drivers are being cautioned about leaving everyday items in their vehicles. Motoring experts warn that common objects can melt, leak, burst, or become hazardous in extreme heat, potentially leading to costly repairs or injuries.
According to Keith Hawes, director of Nationwide Vehicle Contracts, many drivers underestimate how quickly cars heat up. He stated: “What might seem like harmless everyday items can quickly become a safety risk or result in costly damage. Something as simple as a fizzy drink left on a seat or dashboard can expand and burst, leaving drivers with an expensive and time-consuming clean-up. In some cases, it can even damage electronics or upholstery.”
Five Items to Remove From Your Car During a Heatwave
Experts at Nationwide Vehicle Contracts have identified five common items that should never be left in a car during a heatwave to avoid repair bills of up to £1,000.
1. Fizzy Drinks
Heat causes pressure to build inside cans and bottles, leading to swelling and potential explosions. An exploding can creates a sticky mess that is difficult to clean, with professional valeting costing between £50 and £150. If a can bursts while driving, it can distract the driver and cause a safety hazard.
2. Pens
Pens can burst and leak ink as temperatures rise, permanently staining seats and interior trim. In severe cases, drivers may face deep cleaning costs up to £200 or reupholstery bills exceeding £1,000.
3. Air Fresheners
Oil-based air fresheners can melt and leak in high temperatures, damaging dashboards by leaving permanent stains or warping plastic surfaces. Repairs or replacements can cost between £50 and £400.
4. Metal Objects and Seatbelt Buckles
Steering wheels, dashboards, and metal seatbelt buckles can reach dangerously high temperatures in cars parked in direct sunlight. These surfaces pose a risk of minor burns when touched. Drivers are advised to park in the shade and be cautious when entering a hot car.
5. Glasses
Sunglasses or prescription lenses left in direct sunlight can act like a magnifying glass, potentially scorching upholstery, interior surfaces, or even causing a fire.
Take Precautions to Avoid Damage and Injury
Hawes added: “Taking a few moments to remove items from your car or keep them out of direct sunlight can help avoid unnecessary injury and costs.” Drivers are urged to check their vehicles before parking and to store sensitive items in the shade or take them inside.
