EV Care in the 305: Tires, 12‑Volt Batteries & A/C Service You Still Need in 2025

Florida is one of the nation's EV leaders—second in total EV registrations behind California—so more Miami drivers are asking what maintenance still matters. Spoiler: plenty. Your EV still needs alignments, 12‑volt battery care, and A/C service, especially in our heat and humidity. (AFDC data)

1) Tires & Alignment — Instant Torque = Faster Edge Wear

Why it matters: EVs are heavier and deliver torque instantly, which can accelerate shoulder wear and magnify any misalignment.
How to stay ahead:

Rotate every 5–6k miles (or per your owner's manual).
Check pressures monthly (and before road trips).
Mind load index & speed rating—EV‑rated tires handle weight and torque better.
Schedule an alignment after curb hits, potholes, or uneven wear.
Wet‑grip rule of thumb: Replace at ~4/32" for Miami's rainy season.

2) The Small Battery That Can Strand You: 12‑Volt

Yes, EVs still have a 12‑V battery. It powers computers, locks, and closes the high‑voltage contactors so the car can "wake up." A weak 12‑V = no start, even with plenty of range.
Care plan:

Annual 12‑V battery test (pair with tire rotation).
Watch for slow screens, erratic accessories, or alerts after parking.
If the 12‑V is 3+ years old, plan a proactive replacement.

3) A/C Service — Cooling You and (Sometimes) the Battery

Most late‑model vehicles (including many EVs) use R‑1234yf refrigerant. EVs run electric compressors that require non‑conductive, EV‑safe oil; mixing oils or using contaminated machines can damage the compressor.
Care plan:

If A/C gets weak, noisy, or smelly, request a performance check—don't just "top off."
Ensure your shop uses EV‑safe A/C equipment and the OEM‑specified oil to protect the compressor and high‑voltage system.
Replace the cabin air filter 1–2x/year to keep airflow and evaporator odor in check.

Bonus: Brakes on EVs Still Need Love

Regen braking reduces pad wear, but rotors and calipers can rust or stick if friction brakes aren't exercised. Ask for a periodic brake inspection and burnish to keep things clean and responsive.

Quick Miami EV Checklist

Monthly: Check tire pressures; quick tread check; windshield washer fluid.
Every 5–6k miles: Tire rotation + alignment check.
Annually: 12‑V battery test, brake inspection, cabin filter.
Any A/C complaint: Request EV‑safe A/C diagnostics (not just a recharge).
