We do not list a fixed time for this service online; plan for a single appointment the same day.

Actual time varies with shop workload, inspection results, and whether additional charging-system checks or terminal cleaning are needed. Our team aims to complete testing and installation in one visit. You can book a specific time slot and wait in our lounge or arrange a ride after check-in.

• Book a time: schedule appointment
• Add diagnostic/charging-system check if requested
• Ask about same-day availability

Toyota assigns the correct 12‑volt battery by VIN; check your owner’s manual or the under‑hood label for the exact group and CCA.

Battery specifications can vary with engine, equipment, and climate package. To ensure proper fit and reserve capacity, we verify battery group and cold cranking amps against Toyota guidance for your specific vehicle. Bring your Highlander, or share your VIN, and we’ll confirm the exact spec before installation.

• Verify by VIN for precise fit
• Check owner’s manual and battery label
• Match CCA to local climate demands

Most 12‑volt car batteries last about 3–5 years.

In the Phoenix West Valley heat, batteries may age faster due to high under‑hood temperatures. Short trips, infrequent use, and added electrical loads can also shorten life. If your battery is approaching the 4‑year mark, proactive testing reduces the chance of an inconvenient no‑start.

• Heat accelerates battery wear
• Test annually after year 3
• Book a check: schedule service

Common signs are slow cranking, dim lights, battery/charging warnings, electrical glitches, or battery age over 4 years.

These symptoms point to reduced capacity or charging issues that deserve a proper load test. Our factory-trained team can test the battery and assess the alternator and connections to confirm root cause before replacing parts. Book a quick diagnostic to avoid unexpected no-start situations.

• Slow start and flickering interior lights
• Warning icons on the dash
• Free up-front testing when scheduled with service

Parts stores often sell the battery for less, while a dealer install typically includes diagnostic testing, professional installation, and recycling.

Our Toyota-certified technicians verify the correct spec for your vehicle and check the charging system so you don’t replace a good battery when the alternator or connections are at fault. That added verification helps prevent repeat issues and ensures proper fitment and performance.

• OEM-spec options and proper fit
• Charging-system and connection checks
• Old battery disposal handled for you

It’s risky—your vehicle relies on the 12‑volt battery for engine management and safety electronics, and low voltage can cause a stall.

If starting is already slow, voltage may dip further under load, especially with A/C and lights on. Arrange testing and replacement promptly to avoid being stranded. If the car won’t crank or accessories flicker, consider a tow to reduce the chance of control-module voltage drops.

• Schedule help: schedule service
• Minimize electrical loads if you must drive
• Tow if cranking is weak or intermittent

Yes—clock and audio presets may reset, and some features may require a brief relearn after power loss.

A memory saver can preserve settings during service, and most systems relearn quickly after a short drive. If any warning lights appear after installation, a quick scan can clear transient voltage-related codes. Our team can advise on window, sunroof, or steering-angle relearns if needed.

• Bring radio codes if applicable
• Ask for a memory-saver during service
• Take a short drive for system relearn

The 12‑volt battery in this SUV must meet Toyota’s specifications for physical group size, terminal orientation, and cold cranking amps to ensure reliable starts and stable voltage for modern electronics. Exact specs vary by equipment, so we verify by VIN and the under‑hood label before installation. The battery is located in the engine bay, which experiences high temperatures that can shorten service life; periodic testing is recommended. If you’re unsure of the current battery’s health or spec, bring the vehicle by and we’ll confirm fitment and performance requirements.

Bring your 2018 Toyota Highlander to Larry H. Miller Toyota Peoria in Peoria for an OEM-spec replacement — schedule service.

Our process begins with a battery and charging-system check to confirm the root cause of any starting or electrical concern. If replacement is recommended, we match the correct Toyota‑spec battery to your VIN, remove the old unit, inspect and clean terminals as needed, and install the new battery with proper hold‑down torque. We then verify starting performance and system voltage, and handle environmentally responsible recycling of the old battery. If you’d like to preserve in‑car presets, ask about using a memory saver during the service.
