Remember when cars just needed oil changes? Now they need updates like your laptop. Most 2025 vehicles receive over-the-air updates, but don’t assume they’re all automatic.

Check your vehicle app monthly for pending updates. These aren’t just for the infotainment system – they often include crucial power management, safety features, and even brake calibration improvements. Skipping updates can leave performance on the table or, worse, create security vulnerabilities.

Fluid Checks

Traditional fluids still matter, even in the most futuristic vehicles. Brake fluid absorbs moisture over time, reducing its effectiveness regardless of how little you use traditional brakes (regenerative braking handles most slowing in modern EVs).

For hybrids and traditional combustion engines, oil technology has advanced significantly. Most 2025 models use synthetic oils rated for 10,000-15,000 miles, but don’t stretch these intervals in extreme conditions.

Tire Care

With greater torque available instantly in electric motors, tire wear patterns have changed. Rotation schedules are more critical than ever, typically every 5,000-7,000 miles.

The specialized low-rolling-resistance tires on many efficient models require different inflation pressures. Under-inflation by just 5 PSI can reduce your range by up to 10% in some EVs, according to Consumer Reports tire testing.

• Check tire pressure monthly, not just when warning lights appear
• Inspect tread wear patterns quarterly for alignment issues
• Consider seasonal tires if you experience temperature extremes
• Don’t neglect tire rotation, even with all-wheel drive vehicles
