Mercury Insurance Shares the Most Common Maintenance Oversights That Can Lead to Costly Repairs, Summer Breakdowns and Preventable Claims
Vehicle maintenance remains one of the simplest ways drivers can help protect themselves, their passengers and their wallets. According to the National Highway Traffic Safety Administration (NHTSA), proper maintenance helps improve vehicle safety and reliability while reducing the likelihood of roadside emergencies.
"Many vehicle problems start small and become much more expensive when they're ignored," said Justin Yoshizawa, Product Management Director, at Mercury Insurance. "Routine maintenance helps drivers catch issues before they turn into major repairs, and it can make a meaningful difference in both safety and long-term ownership costs."
To help drivers prepare for a busy summer travel season, Mercury identified five common maintenance mistakes that can lead to avoidable expenses and headaches on the road.
1. Ignoring Dashboard Warning Lights
Dashboard warning lights are designed to provide early notice when something needs attention. Yet many drivers continue operating their vehicles for weeks or even months after a warning light appears.
Whether it's a check engine light, oil pressure warning, battery indicator or brake system alert, these warnings often signal problems that can become more serious and expensive if left unaddressed.
Mercury Tip: Don't assume a warning light will go away on its own. Consult your owner's manual and have the issue diagnosed as soon as possible.
2. Skipping Tire Pressure Checks
Tires play a critical role in vehicle handling, braking performance and fuel efficiency, but they are often overlooked until a problem occurs.
Underinflated tires can wear more quickly, reduce fuel economy and increase the risk of tire-related failures. Tire pressure can fluctuate throughout the year due to changing temperatures, making regular checks especially important as summer heat arrives.
Mercury Tip: Check tire pressure at least once a month and before any long-distance trip. Be sure to use the pressure recommendations listed on the driver's side door jamb or in the owner's manual.
3. Delaying Scheduled Maintenance
Oil changes, fluid inspections, brake service and battery checks are easy to postpone when a vehicle appears to be running normally. Unfortunately, deferred maintenance is one of the leading causes of preventable mechanical problems.
Manufacturer-recommended maintenance schedules are designed to address wear-and-tear items before they fail. Skipping routine service can shorten vehicle life and increase the likelihood of more costly repairs later.
Mercury Tip: Follow the maintenance intervals recommended by your vehicle manufacturer, not just when something seems wrong.
4. Waiting Until a Road Trip to Address Problems
Many drivers don't think about vehicle maintenance until they're preparing for a vacation or long weekend getaway. By then, there may not be enough time to identify and resolve issues before hitting the road.
Summer travel places added demands on tires, batteries, cooling systems and other vehicle components. Problems that seem minor during everyday driving can quickly become major inconveniences hundreds of miles from home.
Mercury Tip: Schedule a vehicle inspection several weeks before a major trip to allow time for any necessary repairs or maintenance.
5. Viewing Maintenance as a Cost Instead of Protection
One of the biggest maintenance mistakes isn't mechanical at all. It's the belief that routine maintenance can be postponed to save money.
While delaying service may provide short-term savings, it often increases the risk of larger repair bills later. Preventive maintenance helps protect a vehicle's reliability, performance and resale value while reducing the likelihood of unexpected breakdowns.
Mercury Tip: Think of maintenance as protecting your investment. A small service bill today can help prevent a much larger repair bill tomorrow.
Preparation Pays Off
As summer travel ramps up across the country, Mercury encourages drivers to make vehicle maintenance part of their seasonal preparation checklist.
"Most drivers depend on their vehicles every day, but it's easy to overlook maintenance until something goes wrong," Yoshizawa said. "A little attention now can help drivers avoid unnecessary expenses, reduce the risk of breakdowns and travel with greater confidence throughout the summer."
