The Seldom-Driven Car: Time Can Wear a Vehicle Too

Many people keep a second vehicle for weekends, emergencies, or seasonal use. The car may show very low mileage while sitting for weeks at a time. The problem this creates is not the distance driven but the time between drives, which can allow certain parts and fluids to age in ways that a mileage count does not show. The question is how to tell that the problem is present, and what to record while it is still easy to see.

Count the gaps between drives

Keep a simple log of when the vehicle was last driven and for how long. Long gaps are the first sign. Note also how many trips are short enough that the engine does not fully warm before it stops. Short trips and long rests are a common pattern for a seldom-driven vehicle, and they are worth recording because they can change what the owner's manual and the maintenance schedule call for.

Watch for the signs that appear after rest

Slow starts after a week of rest, a dimmed interior light, or a warning message on the first morning can point to a battery that needs attention. Check the tires for flat spots after the vehicle has sat in one position. Look for a damp, musty cabin, dried rubber on the seals, or fuel that has been in the tank for a long time. These are observations to record, not conclusions. Write down the date you noticed each one and what you did.

Check the storage guidance in the owner's manual

The owner's manual and the factory maintenance schedule describe what the manufacturer expects for long periods without use. Read that section before deciding how to store the vehicle. The Acura MDX model-year record and other records in the library show the line's published information, but the manual for your specific vehicle is the document that applies to it.

Ask how a contract counts time

If the vehicle is covered by a service contract, ask whether the contract's time limit runs whether or not the car is driven. Ask whether any requirement for periodic service applies during a long rest, and how that service is recorded. These are questions to put to the seller or the contract administrator in writing, so the answers are on paper before you need them.
