Nobody can deny that cars made right here in the States are some of the most remarkable feats of automotive engineering. That said, imported cars have something about them that our domestically produced vehicles don’t offer. Some people simply prefer the exotic qualities of high-quality imported vehicles.

Of course, investing in an imported vehicle means getting something not built with the American market in mind. Owning an import vehicle has unique perks, including superior engineering and precision performance. However, a specific approach to maintenance is also required to ensure these vehicles continue running smoothly for years to come.

At Stonum Automotive, we’ve been taking great care of our customers’ auto repair and maintenance needs in Longmont, CO, since 2004. We’ve seen firsthand how routine maintenance can prevent common but avoidable issues.

In this guide, we’ll walk through key maintenance tips and highlight common mistakes to avoid for owners of European, Japanese, and other foreign car brands.

Mistake #1: Failing to Follow Your Vehicle’s Maintenance Schedule

One of the most frequent errors import vehicle owners make is neglecting to follow their car maintenance schedule. While all cars need routine care, import vehicles are often more sensitive to missing regular checkups. Following the manufacturer’s recommended service intervals is essential to keeping your vehicle in optimal condition.

Whether it’s oil changes, tire rotations, or timing belt replacements, sticking to your car’s specific schedule will help prevent unexpected breakdowns and maintain peak performance. Check your owner’s manual for details and avoid missing critical service milestones.

Key Tip: If you’re unsure about your car’s recommended service intervals, consult our car maintenance schedule for guidance.

Mistake #2: Neglecting Regular Oil Changes

Oil is the lifeblood of your vehicle’s engine, and skipping regular oil changes is one of the most damaging mistakes an owner can make. Fresh oil lubricates the engine, reduces wear, and helps dissipate heat. Running your car on old or insufficient oil can lead to engine damage, reduced performance, and, in some cases, complete engine failure.

Import vehicles, particularly high-performance models, often require specific oil types and more frequent oil changes than domestic vehicles. Use the correct oil for your vehicle’s engine and stick to the manufacturer’s recommended change intervals.

Schedule your next oil change with Stonum Automotive to ensure your vehicle stays in top shape.

Mistake #3: Ignoring Brake Maintenance

Your brakes are a crucial safety feature, and delaying inspections or repairs can risk your vehicle and your safety. Regular brake inspections are necessary to check for wear on brake pads, rotors, and other components. Many import vehicles have specialized braking systems that require precise care and attention.

Common signs of brake issues include squeaking, grinding, or a spongy brake pedal. If you notice any of these symptoms, it’s important to have your brakes inspected immediately. Putting off brake maintenance can lead to more expensive repairs and jeopardize your vehicle’s stopping power.

For peace of mind, set up regular brake inspections with Stonum Automotive’s team of experienced mechanics. We’ll ensure your brake system works properly and catch any issues early on.

Mistake #4: Overlooking Engine Diagnostics

A small issue with your engine can escalate quickly if not diagnosed in time. Unfortunately, many drivers wait until a dashboard warning light comes on before taking action. By that point, the problem may have already caused significant damage.

We recommend having engine diagnostics done regularly to catch problems before they worsen. This is especially important for import vehicles, which often feature more complex engine designs. Stonum Automotive uses advanced diagnostic tools to pinpoint any underlying issues and address them promptly, ensuring your engine runs smoothly for the long haul.

If you notice unusual sounds, smells, or a reduction in performance, don’t wait for it to get worse—let us help you diagnose and repair the issue.

Mistake #5: Delaying Transmission Maintenance

Transmission issues can be a costly headache if ignored. One common mistake is neglecting transmission fluid changes, vital for the smooth operation of your vehicle’s transmission. Import vehicles, particularly those with automatic or dual-clutch transmissions, require specialized fluid and routine checks to prevent wear and tear.

If your car struggles to shift gears or you notice fluid leaking, it’s time to have your transmission inspected. Keeping up with maintenance will help you avoid costly transmission repairs or replacements in the future.

Stonum Automotive offers professional transmission services, including fluid changes and full diagnostics. If you think your import vehicle’s transmission needs a fluid change, don’t waste time. Reach out because we can help!

Mistake #6: Using Low-Quality Parts

Another common mistake is opting for cheaper, lower-quality parts when servicing your import vehicle. While this may save money in the short term, it often results in poor performance and can even damage your car. Import vehicles are designed with precision, and using subpar parts can compromise that design.

At Stonum Automotive, we recommend using original equipment manufacturer (OEM) parts or high-quality alternatives specifically designed for your car. Our ASE-certified mechanics are experienced in working with foreign vehicles and understand the importance of using the right parts for each repair.

Mistake #7: Ignoring Tire Maintenance

Tires are often overlooked, but proper tire maintenance is key to your vehicle’s safety and performance. Many import vehicles come with performance tires that require specific care, including regular rotation, balancing, and pressure checks. Failing to maintain your tires can lead to poor handling, reduced fuel efficiency, and even blowouts.

We recommend checking your tire pressure regularly and inspecting your tires for uneven wear. Rotating your tires according to the manufacturer’s guidelines will help them wear evenly and last longer.

If you’re unsure when your tires were last checked, schedule your next maintenance appointment with Stonum Automotive and let us handle the rest.

Mistake #8: Overlooking Battery Maintenance

While it’s easy to assume your car’s battery will last for years without issues, imported vehicles often come with additional electrical systems that can put more strain on the battery. Ignoring battery maintenance or failing to test your battery can leave you stranded when you least expect it.

We recommend inspecting your battery during routine maintenance appointments to ensure it’s holding a charge and functioning correctly. If your battery is nearing the end of its life, we can replace it before it fails and causes further inconvenience.
