Car Maintenance You Need Even If You Don’t Drive Much

If you’ve found yourself driving less lately—maybe because you work from home, have a second car, or just don’t rack up many miles—it’s easy to think your vehicle doesn’t need as much maintenance. But that assumption can lead to some expensive surprises.

Even when your car isn’t being driven regularly, things like oil, rubber, and fluids continue to break down with time. Batteries lose charge. Brakes can develop rust. And problems can sneak up just when you’re ready to go.

This guide covers the key maintenance your vehicle still needs—even if the odometer is barely moving.

1. Oil Changes – Yes, Even When Your Car Isn’t Moving

It might seem logical to delay an oil change if you’re not driving much, but oil doesn’t just degrade from use—it breaks down with time. Moisture and temperature changes can cause oil to lose its lubricating properties, turning it into sludge that clogs your engine.

While there’s no public stat on how many engines seize from skipped oil changes, the CarMD Vehicle Health Index regularly ranks engine damage from oil neglect—like low oil levels or sludge buildup—as one of the most expensive and preventable repairs. Mechanic networks like RepairPal also report oil neglect as a leading contributor to major engine failures.

Most automakers recommend changing your oil at least once a year, even with low mileage. And they often warn that skipping oil changes can cause serious engine damage—or void your powertrain warranty.

2. Battery Maintenance – Sitting Too Long Can Leave You Stranded

Batteries slowly discharge even when the car is off. Modern vehicles continue to draw small amounts of power for systems like the clock, alarms, and onboard electronics. If a car sits idle for too long, especially in cold or hot weather, the battery can lose its charge entirely.

Roadside assistance providers like AAA consistently report that battery-related service calls double—or even triple—during colder months. And many of those calls come from cars that haven’t been driven regularly.

• Start it once a week and let it run for 10–15 minutes

• Take it for a short drive (idling alone isn’t enough)

• Consider a battery maintainer for long-term storage

Most car batteries last 3–5 years, but infrequent use can shorten that lifespan significantly.

3. Tire Care – Tires Age, Even When They Look Fine

Tires don’t just wear from driving—they also break down from exposure to sunlight, moisture, and time. When a car stays parked for too long, tires can develop flat spots or start to dry rot, especially in extreme weather conditions.

The National Highway Traffic Safety Administration recommends replacing tires every six years, regardless of tread depth. That’s because rubber naturally degrades with age, and visual inspections don’t always reveal internal damage.

Underinflated tires are another hidden issue. Tires lose air slowly over time, and driving on low pressure can affect fuel efficiency, handling, and tread life.

• Check tire pressure monthly

• Look for cracks, bulges, or uneven wear

• Move the car occasionally to prevent flat-spotting

4. Brake System – Rust Doesn’t Take Long to Set In

When brakes sit unused, especially in humid or coastal environments, rust can form on the rotors. That surface rust may wear off during normal driving, but over time it can lead to pitting, brake noise, vibration, or sticking components.

Brake system issues are among the most common repairs reported by auto shops. In CarMD’s national repair data, brake-related problems consistently rank in the top five—often showing up in cars that aren’t driven regularly.

• Drive the car at least every week or two

• Watch for squeaking, grinding, or a “soft” brake pedal

• Get your brakes inspected once a year, even with low mileage

5. Fluids and Filters – Quiet, but Critical

Even when your car is parked, fluids like coolant and brake fluid continue to degrade. Coolant can become acidic, losing its ability to protect the engine from corrosion. Brake fluid absorbs moisture over time, which reduces its performance.

Manufacturers generally recommend replacing:

• Coolant every 2–3 years

• Brake fluid every 2 years

• Cabin air filter once a year, especially if parked outside

And while you may not think much about your cabin air filter, it collects dust, pollen, and moisture even when the vehicle isn’t in use—leading to musty smells and reduced airflow when you finally turn on the A/C.

These aren’t major repairs, but ignoring them can lead to bigger problems that are far more expensive to fix.

Driving less comes with some nice perks—lower fuel bills, fewer maintenance appointments, and less wear on your vehicle overall. But low mileage doesn’t mean no maintenance.

Some of the most expensive repair issues mechanics see actually come from cars that sit too long without attention. A simple, time-based maintenance routine—like annual oil changes, fluid checks, and occasional drives—can keep your car reliable and ready whenever you need it.

Because whether it’s a last-minute trip, an unexpected errand, or just a weekend cruise, it’s always better to turn the key and know your car is good to go.

If your car has been sitting more than it's been driving, it might be the right time to consider an upgrade. A newer model could better match your current routine—and you might get more for your trade-in than you think. Explore our latest inventory to see what fits your lifestyle now.

Why Matching Tires is Crucial for AWD and 4WD Vehicles

If you’ve ever driven an all-wheel-drive (AWD) or four-wheel-drive (4WD) vehicle, you know how reliable they are in tough conditions. Whether you’re navigating icy roads, muddy trails, or everyday commutes, these systems are built to keep you safe and in control.

But there’s one small mistake that could leave you going from a flat tire to flat broke replacing that damaged tire with the wrong one. It might seem harmless at first, but mismatched tires can lead to costly damage down the road. Let’s dive into why matching tires is so important for AWD and 4WD vehicles and how to avoid an expensive repair bill.

What Makes AWD and 4WD Different?

At first glance, AWD and 4WD might seem interchangeable—they both power all four wheels, right? While that’s true, these systems are designed for different purposes and operate in unique ways:

All-Wheel Drive (AWD)

• Automatic Adjustment: AWD systems are “always on” and work automatically. They constantly monitor road conditions and wheel traction, distributing power between the front and rear wheels as needed.

• Best for Everyday Conditions: AWD is ideal for roads that occasionally get slippery—think rain, snow, or light off-road trails. It’s great for drivers who want added security without having to think about it.

• Traction on Demand: Modern AWD systems use advanced sensors and computers to decide which wheels need power and when. For example, if the front wheels start to slip, power is quickly redirected to the rear wheels to keep you stable.

• Vehicles with AWD: You’ll often find AWD in cars, crossovers, and SUVs designed for on-road driving with some off-road capability.

Four-Wheel Drive (4WD)

• Manual Engagement: 4WD systems typically require the driver to engage the system manually (often using a lever, button, or dial). This means you choose when to activate it, usually in rough or slippery conditions.

• Designed for Tough Terrain: 4WD is built for serious off-road adventures. It’s designed to handle rocky trails, deep mud, sand, and steep inclines that demand maximum traction.

• Power to All Wheels Equally: When 4WD is engaged, power is evenly distributed to all four wheels, giving you maximum torque and grip. Some systems also include low-range gearing for extra control on challenging terrain.

• Vehicles with 4WD: You’ll find 4WD on trucks, SUVs, and other vehicles built for rugged environments.

Key Difference: Think of it this way—AWD is like having an automatic helper that adjusts to keep you safe in day-to-day driving conditions. 4WD, on the other hand, is a tool you use when the going gets tough and you need maximum capability.

The Common Mistake: Replacing Just One Tire

Here’s a scenario that happens all the time: You’re driving along, and suddenly—flat tire. You take your AWD or 4WD vehicle to the nearest tire shop, and the bad news comes in: the tire can’t be repaired.

Now you’ve got a decision to make. The shop doesn’t have your exact brand or model in stock, and replacing all four tires feels expensive. So, you agree to replace just the one tire with something “close enough.” Problem solved, right?

Not exactly.

At first, everything seems fine. But over time—maybe weeks or months—you might notice some strange vibrations, odd noises during turns, or even a dip in fuel efficiency. By the time you bring the car in for inspection, the damage is done: your drivetrain has been working overtime trying to adjust for that mismatched tire. Now, you’re looking at costly repairs to components like the differential or transfer case.

Why Do Matching Tires Matter So Much?

• Consistent Rolling Speeds: If one tire is slightly larger or smaller, it will rotate at a different speed, confusing the system and forcing it to overcompensate.

• Preventing Strain on the Drivetrain: Uneven tires create extra work for components like the differential and transfer case, leading to unnecessary wear and tear.

• Maintaining Traction and Control: Mismatched tires can reduce your vehicle’s stability and handling, especially in challenging conditions like snow or rain.

• Avoiding Expensive Repairs: Over time, that extra strain can lead to costly repairs or replacements of major components.

What Should You Do If You Have a Flat Tire?

If you’re dealing with a flat tire on your AWD or 4WD vehicle, here’s how to handle it the right way:

1. Get the Correct Tire: Always replace the damaged tire with one that matches the others in brand, model, size, and tread pattern. It’s non-negotiable for AWD and 4WD vehicles. If the tire shop doesn’t have the exact match in stock, ask them to order it. Avoid installing a mismatched tire as a quick fix.

2. Replace All Four Tires if Necessary: If your other tires are significantly worn, replacing all four ensures they’re perfectly matched. This is the best way to avoid problems with uneven tread depth or rolling circumference.

3. Follow Manufacturer Recommendations: Check your owner’s manual for tire specifications. The manufacturer’s guidelines are there to help you keep your vehicle running safely and efficiently.

4. Use a Temporary Spare Wisely: If you need to use a spare tire (like a smaller “donut”), treat it as a short-term solution. Drive carefully and get the correct tire installed as soon as possible.

5. Ask for Professional Advice: Not sure what to do? Talk to a tire expert who understands AWD and 4WD systems. They can guide you toward the best solution for your vehicle.

Recognizing the Warning Signs of Mismatched Tires

If mismatched tires are already causing issues, you might notice:

• Vibrations while driving.

• Odd noises during turns.

• Reduced fuel efficiency.

• Uneven or accelerated tire wear.

If you spot these signs, take action quickly to avoid further damage to your drivetrain.

Protect Your AWD or 4WD Vehicle

Matching tires is not just a recommendation for AWD and 4WD vehicles—it’s a necessity. Even small differences can lead to significant strain on your vehicle, reducing performance and leading to costly repairs. By replacing all four tires when possible, following manufacturer recommendations, and seeking professional advice, you’ll keep your vehicle safe, efficient, and reliable.

Little Mistakes That Can Lead To Big Car Repair Bills

As anyone who’s ever owned a car knows, they are a huge financial responsibility. Aside from the initial purchase price, there’s insurance, gasoline, and of course, repairs and maintenance.

While some car repairs are unavoidable, there are others that are totally avoidable if you take proper care of your vehicle. Here are a few of the most costly car repairs that are avoidable with some simple preventive maintenance.

Never Ignore The Check Engine Light

Ignoring the check engine can lead to major engine damage that could have easily been avoided had the problem been addressed immediately. There are many reasons the light comes on such as a loose gas cap, bad oxygen sensor, or failed catalytic converter.

Failing To Replace The Battery When Needed

Depending on the battery's condition, most last anywhere from three to five years. If you're still driving on the original battery that came with the car, chances are it needs to be replaced. Modern vehicles are full of electronic features that put a strain on the electrical system, and an old battery will struggle to keep up.

If your battery is drained, it will take longer for your starter to turn over. Your vehicle now draws more electricity, and the alternator kicks in to throw additional amps at the battery in order to recharge it. All those things drawing current can be affected by the spikes and lows over time.

It's easy to eliminate a lot of electrical problems by replacing the battery when needed

Not Maintaining Proper Fuel Level.

Electric fuel pumps are located in the fuel tank. Running the pump dry can damage it. The debris from the bottom of the tank will also get into the fuel filter and clog it. This will reduce fuel flow to the engine and cause all sorts of drivability problems.

If you allow the fuel level to constantly run lower than a quarter tank full, you run the risk of having  to replace the fuel pump sooner than necessary. It sounds weird but gasoline has a cooling effect on the fuel pump, and running low all the time could potentially shorten its lifespan

Unnecessary Transmission Flushes

If you know the history of your car, it may be okay to do transmission flushes just as your preventative maintenance suggests. However If you don't know the history and the car is running fine, then you might reconsider getting it done.

When you fill your car with new transmission fluid, it has specially designed detergent in it to keep a transmission clean. The issue is that it can break loose debris already present in the transmission resulting in a clogged filter. If the filter gets clogged, it will restrict fluid flow and cause all sorts of problems.

Not Using The Proper Tire Size

Whether it's a spare tire or just buying tires not rated for your vehicle, putting the wrong size tire on your car will cause problems. The spare tire is rated for a limited amount of miles and speed, so you should only use it in an emergency situation.

When you drive with mismatched tire sizes, it can cause the vehicle's differential to think that the smaller tires are slipping. It then tries to compensate by sending more power to the wheels, which can cause even more tire slippage and eventually lead to differential failure.

Kicking Ice & Sludge To The Curb

You may just do it without thinking but kicking ice and sludge off your car's bumper, fender and doors can cause cracks or damage to plastic moldings. Think about it this way. When the temperature gets below freezing plastic can become very brittle.

So if you're tempted to kick your bumper, Don't. It could easily crack and need to be replaced. The same goes for plastic moldings and door handles. If possible wait for warmer temperatures, spray it off with a high pressure water nozzle at a car wash or just gently use a soft bristle brush.

The Safe Way to Defog Your Windshield

Driving with a clear view is not just a matter of convenience; it's a critical safety necessity. A fogged-up windshield can transform an ordinary drive into a perilous endeavor, significantly increasing the risk of accidents. When visibility drops, so does your ability to respond to road conditions and hazards.

We'll dive into the science behind windshield fog and offer practical, safety-first techniques to ensure you maintain the clearest view possible. Whether you're facing the early morning chill or the humid evening return from work, understanding how to quickly and safely defog your windshield is key to a safe journey. Let's clear things up.

Understanding Windshield Fog

Why Windshields Fog Up:
Imagine your vehicle as a contained climate system. The warm air, cozy from your car’s heating system or simply from passengers, confronts the cold surface of the glass and rapidly cools down, shedding its moisture as condensation. This process results in a fine mist of droplets clinging to the inside of your windshield, scattering light and obscuring your view.

Understanding the Risks:
Compromised visibility due to fogged glass is a serious safety hazard. Inadequate visibility means you are less likely to notice pedestrians, other vehicles, and road signs in time to react appropriately. It's essential for the safety of yourself and others to maintain a clear windshield and ensure full visibility at all times.

Preventative Measures

Anticipating fog before it happens can help you maintain a clear windshield and improve safety. Here are some measures to prevent your windshield from fogging:

Ventilate Your Vehicle:
To prevent condensation, it’s beneficial to allow the interior of your car to ventilate, especially overnight. Leaving your windows slightly open can balance the inside and outside temperatures, reducing the likelihood of fog formation.

Regular Maintenance Checks:

• Cabin Air Filters: Keep your cabin air filters clean to ensure adequate airflow, which is vital for effective defogging.

• HVAC System: Regular checks on your heating, ventilation, and air conditioning system can help prevent fogging by ensuring it operates efficiently.

Pre-emptive Climate Control:
Before exiting your vehicle, switch to fresh air mode to expel moist air and cool the interior, reducing the chance of fogging when the vehicle is next used.

Defogging Techniques for Safety

When faced with a fogged windshield, you need to act fast, but always with safety in mind. Here’s what to do:

1. Start Your Engine: Before driving, start your car and begin the defrost cycle to enhance visibility.

2. Use the Defroster: Engage the defroster to warm the windshield and evaporate condensation.

3. Adjust the Airflow: Direct vents towards the windshield and side windows to disperse the fog.

4. Temperature Settings: Adjust the temperature to match the exterior conditions—warm to counteract cold, cool for warmth.

5. Activate the A/C: Use the air conditioning to dehumidify the cabin and clear the fog faster.

6. Turn Off Recirculation: Switch off the recirculation to allow dry outside air to enter the vehicle.

Safety Tips While Defogging:

• Do Not Drive Blindly: Ensure at least partial visibility before starting to drive and pull over if visibility is impaired while driving.

• Use Wipers: Utilize your windshield wipers to clear external condensation.

• Window Cracking Technique: Slightly open windows to balance the internal and external climate, aiding the defogging process.

• Manual Wiping: If necessary, use a clean microfiber cloth to manually clear the fog.

• Regular Cleaning: Maintain a clean windshield to prevent excessive fogging.

Remember, arriving safely is more important than arriving on time. It's better to delay your trip momentarily than to drive with obscured visibility.

Choosing the Right Products

Using the appropriate products is crucial for effective defogging and safety. Here are some recommendations:

• Anti-Fog Solutions: Opt for automotive-specific products like Stoner Invisible Glass Anti-Fog or Rain-X Anti-Fog, which prevent moisture build-up on the glass.

• Cleaning Solutions: Use automotive glass cleaners designed for vehicle interiors that do not leave residues.

• Cloths and Tools: Employ microfiber cloths for their lint-free and streak-free properties, and keep a squeegee handy for quick moisture removal.

Safety Considerations:

• Test products on a small area of the glass to ensure they do not obstruct visibility.

• Confirm that the products used do not interfere with windshield sensors or cameras, especially in vehicles with ADAS.

Be proactive in maintaining your vehicle's defogging capabilities. Keep the necessary tools on hand, regularly check your car's systems, and pull over if your visibility is compromised. Remember, safe driving is not just about reacting to conditions; it's about being prepared for them. Drive safely, stay visible, and enjoy the clarity of your journey.

How To Check Your Antifreeze

It may not cross most people's minds, but checking your car's antifreeze protection level is an important part of regular maintenance. Anti-freeze helps protect your car from damage caused by cold weather, and keeping it at the proper level could save you from costly repairs down the road. In this article, we will show you how to check your car's antifreeze protection level and what to do if it needs to be adjusted.

What You Need

Before you begin, there are a few items you need for the job:

• An anti-freeze tester: These are usually sold for just a few dollars at any auto parts store.

• Paper towel or rag: This will help keep the anti-freeze off of surfaces like paint that could get damaged.

• Ziplock bag: This will help keep dirt out of your anti-freeze tester while you’re not using it.

Step 1: Locate The Reservoir

The first step is to locate the reservoir where your car’s anti-freeze is stored. This is usually in the engine compartment, and it looks like a plastic container with a lid on top (as seen in Figure 1). There should also be a warning label telling you not to open the lid while the fluid is hot – so always make sure that your car has been sitting idle for at least two hours before proceeding! 

Step 2: Testing The Anti-Freeze

Now that you have located the reservoir, insert the end of your tester into the fluid (you may have to use a straw attached to the bottom of the tester). Then pump up and down until about half of the fluid has been drawn up into the glass chamber on top (Figure 2). Now look at how many “balls” are floating on top of the fluid; this number tells you how well protected your car is against extreme cold temperatures (see Table 1 below). Once done testing, pour any remaining liquid into its original container, then wipe off any residue with paper towel or rag. 

Step 3: Storing The Tester

After testing, take a ziplock bag and store your anti-freeze tester in it until its next use. This will help keep dust and dirt off of it when it’s not in use! And don't forget - always remember that antifreeze is poisonous so make sure none gets on any surfaces outside of its original container!   

Checking your car's antifreeze protection level doesn't have to be difficult or complicated; with these simple steps anyone can do it themselves! With regular testing every few months, you'll know exactly how well protected against extreme cold temperatures your vehicle really is - potentially saving yourself hundreds or thousands of dollars in repairs down the line!
