Introduction
As the long, sun-soaked days of summer begin to shift into the cooler, crisper air of fall, it's the perfect time for San Diego drivers to think about seasonal car care. While we may not get snow or frost like other regions, climate change, increased chance of rain, and shorter daylight hours can still affect your vehicle’s performance.
At Import Auto Specialists, we know how easy it is to overlook maintenance when your car seems to be running fine. But preventive maintenance is the key to avoiding unexpected breakdowns, preserving your vehicle’s value, and staying safe on the road. Whether you drive a sporty Audi, a reliable Toyota, or a luxurious Mercedes-Benz, a few simple steps this fall can keep your car in top shape well into the winter months.
1. Inspect Your Brake System
Fall often brings light rain to San Diego—just enough to make roads slick with oil and debris buildup. That’s why your brake system should be a top priority this season. Worn brake pads or rotors can significantly reduce your stopping power, especially in wet conditions.
If you hear squeaking, grinding, or feel vibration when you brake, it’s time to get your system inspected. Even if everything seems fine, a seasonal brake check ensures peace of mind. At Import Auto Specialists, our ASE-certified technicians will inspect the pads, rotors, calipers, and brake fluid to make sure everything’s working properly.
Pro tip: Brake fluid should be flushed about every 2 years—especially important in humid climates where moisture can enter the system.
2. Check & Replace Fluids as Needed
Fluids are crucial for every system in your car, and with temperature fluctuations, even in San Diego’s mild fall weather, keeping them fresh and at the right levels is key.
Here’s your fall fluid checklist:
Engine Oil: Old oil breaks down and loses effectiveness. If you’re due for an oil change—or close—fall is a great time to do it.
Coolant/Antifreeze: Yes, even in Southern California, your vehicle needs a proper coolant mixture to prevent corrosion and regulate temperature.
Brake Fluid: Aged or contaminated fluid compromises performance.
Transmission Fluid: If it’s low or dirty, it can lead to slipping or harsh shifting.
Windshield Washer Fluid: Rain brings debris—make sure your wipers and fluid can keep your windshield clear.
Our team can inspect all of these fluids and recommend service where needed.
3. Tire Care: Pressure, Tread & Rotation
Your tires are your first line of defense between your car and the road. With cooler overnight temperatures, tire pressure can drop—impacting handling, fuel economy, and safety.
Use a digital tire gauge to check pressure monthly and inflate to your manufacturer’s specifications. And don’t forget to:
Inspect tread depth using the penny test.
Check for cracks, bulges, or uneven wear.
Schedule a rotation if it’s been over 5,000 miles.
A properly inflated and rotated set of tires will last longer and help you stay safe on those unexpectedly rainy days.
4. Battery & Electrical System Check
Fall mornings may not be freezing, but the seasonal dip in temperature can still impact battery performance, especially if your battery is 3+ years old. A weak battery in cooler weather might leave you stranded on the way to work or your next weekend adventure.
We’ll test your battery’s voltage and cold cranking amps (CCA), inspect for corrosion, and check the alternator to ensure everything’s charging properly.
Remember: Your electrical system also powers your headlights, taillights, and dashboard features. Shorter days mean more night driving, so let’s make sure you can see and be seen.
5. Wiper Blades & Visibility
If your wipers are streaking or skipping, that’s a sign they need to be replaced. In Southern California, many people go months without using them—so by fall, rubber blades may have dried out or cracked under the summer sun.
We recommend:
Replace wiper blades at least once a year.
Topping off the washer fluid with a rain-repellent blend.
Check your windshield for chips or cracks that can worsen with moisture and temperature changes.
Visibility is safety—and it only takes a minute to fix!
6. HVAC System & Cabin Air Filter
As the temperatures cool, you’ll likely switch from A/C to heat—and possibly use your defrost settings more frequently. This is a great time to make sure your HVAC system is functioning properly.
If you’ve noticed:
…it could be time to replace your cabin air filter or service the ventilation system.
A clean filter also improves air quality in the cabin, especially if you suffer from allergies.
7. Undercarriage & Exterior Check
Even though it’s not winter, fall can still be messy. Leaves, mud, and debris can clog drains, accumulate in the undercarriage, and reduce airflow around important systems.
At Import Auto Specialists, we offer undercar inspections to check for:
We’ll also inspect your exterior seals and weather stripping to prevent rainwater from leaking into your interior during those surprise showers.
