10 preventative maintenance items many drivers skip (but shouldn’t)

At Garrett Auto, we see the mechanical consequences of skipped maintenance across Michigan — from salt-eaten underbodies to batteries that fail in subzero mornings. This article walks through 10 routine items drivers often miss, explains why each matters in Michigan, and gives practical steps you can take to avoid expensive breakdowns.

Why small things ignored become big problems in Michigan

Michigan’s combination of long winters, road salt, deep potholes, and a mix of city stop-and-go and long highway runs accelerates wear on parts many owners take for granted. A neglected small item can turn into a safety risk or a major repair — and often happens at the worst possible time: during a winter commute or on a lakeshore weekend trip.

The 10 maintenance items — practical, Michigan-focused advice

1. Tire pressure, tread depth, and spare readiness

   Underinflated tires reduce traction in snow and increase wear. Check pressure monthly and before long trips, and measure tread depth (4/32" or less is risky in snow). Don’t forget the spare: a flat on a rural Michigan road is a long delay if your spare is flat too.

2. Wheel alignment and balancing

   Potholes and rough road patches in many Michigan cities knock wheels out of alignment. Poor alignment causes uneven tire wear, pulls on steering, and worsens fuel economy. If you feel steering vibration or your car pulls, get an alignment and balance check soon.

3. Brake system check beyond pads

   Drivers often only notice thinning pads. But contaminated brake fluid, corroded lines, and glazed rotors are common in salted regions. A full brake inspection — fluid, pads, rotors, lines, and parking brake — improves stopping confidence on icy roads.

4. Coolant and freeze protection

   Old or improperly mixed coolant can freeze or corrode the cooling system. Flush schedules vary, but testing freeze protection and coolant condition every 2–3 years is a good habit in Michigan to prevent a winter breakdown or a failed water pump.

5. Battery checks and terminal care

   Batteries lose capacity faster in cold weather, and corroded terminals increase starting resistance. Test battery health before winter, clean terminals, and replace weak batteries to avoid a morning no-start when temps dip below freezing.

6. Air filters — engine and cabin

   Clogged engine air filters reduce efficiency and performance; dirty cabin filters limit defrosting and HVAC performance (critical for windshield visibility in Michigan blizzards). Replace filters on schedule and after dusty road work or rural drives.

7. Transmission fluid and driveline inspection

   Transmission strain shows up when towing, hauling, or from stop-and-go traffic. Many drivers skip fluid checks until slipping appears. Regular checks and service intervals reduce long-term transmission damage, especially for vehicles used for lake-season trailers or frequent highway travel.

8. Suspension and steering components

   Worn shocks, struts, tie rods, or ball joints change handling and increase tire wear. Michigan’s potholes speed this wear. Have these inspected during oil changes or tire services — catching a bad tie rod early prevents a dangerous failure on a winter road.

9. Wiper blades and washer system maintenance

   Visibility is a safety system. Replace worn blades before first heavy snow, use washer fluid rated for winter, and clear nozzles of ice. Keep a winter blade and a small bottle of fluid in the trunk for unexpected storms on I-75 or US-23.

10. Undercarriage, exhaust, and rust-prone areas

    Salt accelerates corrosion in the underbody, fasteners, exhaust, and suspension mounts. Regularly inspect and rinse the undercarriage, watch for exhaust leaks, and address rust spots before they undermine structural components.

Simple preventive actions you can take today

• Keep a tire gauge and check cold tire pressure monthly.
• Note unusual noises, pulls, or vibrations — don't assume they'll go away.
• Keep routine service dates recorded in the glovebox to track filter and fluid intervals.
• Rinse the undercarriage after heavy salt exposure when possible.

Real Michigan examples

Example — A Lansing driver ignored a small vibration and 8 months later a broken wheel bearing left them on a weekend trip to the lakeshore. Early inspection would have prevented the tow and overnight delay.

Example — A driver who rode their battery through two winters learned the hard way: what felt like a minor sluggish start turned into a dead battery on a subzero morning. A simple load test before winter would have flagged the issue.

When to DIY and when to call a pro

Basic checks — tire pressure, fluid levels, wiper replacement — are fine for most owners. But anything involving suspension disassembly, transmission service, brake system bleeding, or corrosion repairs should be handled professionally. Garrett Auto inspects items holistically and can recommend a prioritized plan that fits your driving patterns across Michigan.

Prioritizing these ten items will reduce surprises, improve safety, and keep repair bills reasonable through Michigan's demanding seasons. Small investments now often pay for themselves in avoided roadside calls and longer component life.
