Maintenance schedule generator

Calendar due times are estimates from your yearly mileage, even when you enter service mileages. We do not store service dates. Check the calendar limits in your owner's manual against dated service records: an item can be due by age even when this checklist says OK.

• Engine oil & filterDue now (estimated)

  Your odometer is sitting on a service point for this item — check whether it has been done.

  Every 7,500 miles or 12 months, whichever comes first. Many modern cars on synthetic oil go 7,500–10,000 miles, but oil ages in the sump too — manuals cap it at 6–12 months. Short trips and towing count as severe service.

• Tire rotationDue now (estimated)

  Your odometer is sitting on a service point for this item — check whether it has been done.

  Every 7,500 miles or 12 months, whichever comes first. Rotation evens out wear — EVs wear tires faster due to weight and torque. Check pressures at the same time.

• 12V battery testOK (estimated)

  Estimated due at 48,000 mi (about 3 months), assuming the last one was at 36,000 mi.

  Every 15,000 miles or 12 months, whichever comes first — at 12,000 miles a year the 12-month limit is estimated to arrive first, about every 12,000 miles. Batteries die on a calendar — typically 3–5 years (EVs still have a 12V battery). Free testing at most parts stores; test yearly and replace proactively before winter.

• Brake inspection (pads, rotors, lines)OK (estimated)

  Estimated due at 48,000 mi (about 3 months), assuming the last one was at 36,000 mi.

  Every 12,000 miles or 12 months, whichever comes first. EV/hybrid pads last longer thanks to regen braking, but rotors can corrode from light use — inspect at least yearly however little you drive.

• Wheel alignment checkOK (estimated)

  Estimated due at 48,000 mi (about 3 months), assuming the last one was at 36,000 mi.

  Every 15,000 miles or 12 months, whichever comes first — at 12,000 miles a year the 12-month limit is estimated to arrive first, about every 12,000 miles. Check yearly, after hitting potholes or curbs, or if the car pulls or the wheel sits off-center.

• Wiper bladesOK (estimated)

  Estimated due at 50,000 mi (about 5 months), assuming the last one was at 40,000 mi.

  Every 10,000 miles or 12 months, whichever comes first. Really a 6–12 month item — replace when they streak, chatter, or smear. Sun and ice shorten their life.

• Brake fluid replacementOK (estimated)

  Estimated due at 60,000 mi (about 15 months), assuming the last one was at 30,000 mi.

  Every 30,000 miles or 36 months, whichever comes first. Brake fluid absorbs moisture whether you drive or not, lowering its boiling point — which is why this one is usually a 2–3 year job, not a mileage job.

• Cabin air filterOK (estimated)

  Estimated due at 60,000 mi (about 15 months), assuming the last one was at 40,000 mi.

  Every 20,000 miles or 24 months, whichever comes first. Replace sooner if airflow from the vents drops or you notice musty smells.

• Engine air filterOK (estimated)

  Estimated due at 60,000 mi (about 15 months), assuming the last one was at 30,000 mi.

  Every 30,000 miles or 36 months, whichever comes first. Dusty roads shorten the interval. A clogged filter hurts power and economy.

• Engine coolantOK (estimated)

  Estimated due at 60,000 mi (about 15 months), assuming the last one was at 0 mi.

  Every 60,000 miles or 60 months, whichever comes first. Long-life coolants can go 100,000 miles, but the corrosion inhibitors deplete on a clock — follow your manual's time or mileage limit, whichever comes first.

• Transmission fluid serviceOK (estimated)

  Estimated due at 60,000 mi (about 15 months), assuming the last one was at 0 mi.

  Every 60,000 miles or 72 months, whichever comes first. 'Lifetime' fluid still degrades; towing and hills call for the severe interval. EVs have no multi-gear transmission to service.

• Serpentine / accessory beltOK (estimated)

  Estimated due at 84,000 mi (about 3 years), assuming the last one was at 0 mi.

  Every 90,000 miles or 84 months, whichever comes first — at 12,000 miles a year the 84-month limit is estimated to arrive first, about every 84,000 miles. Rubber perishes with age as well as mileage. Inspect for cracks and glazing at every oil change after 60,000 miles; a snapped belt stops the alternator and water pump.

• Spark plugsOK (estimated)

  Estimated due at 90,000 mi (about 4 years), assuming the last one was at 0 mi.

  Every 90,000 miles. Wear, not age, kills plugs, so this one is mileage-only. Iridium/platinum plugs commonly last 60,000–100,000 miles; copper plugs far less. Use your manual's spec.
