Which Battery Is Right for My Lexus? Types, Signs and Replacement

Lexus Battery

Whether you drive a luxurious ES or a versatile RX, the battery plays a vital role in performance and reliability. Every Lexus has a 12-volt battery that starts the vehicle and powers its electronics, and Lexus hybrid models also have a separate high-voltage hybrid battery. This guide explains the battery types Lexus uses, the warning signs that a battery is failing and what to do about it. Our Longo Lexus team in El Monte, California, is here to help if you need a replacement.

Does Your Lexus Have One Battery or Two?

It depends on the model:

  • Gas-powered Lexus models have a 12-volt battery that cranks the engine and runs the lights, infotainment and other electronics.
  • Lexus hybrids and plug-in hybrids have two batteries: the high-voltage hybrid battery that helps power the vehicle, and a 12-volt battery that runs the vehicle's systems and gets it started.
  • Battery-electric Lexus models use a large high-voltage battery pack for propulsion, along with a 12-volt battery for accessories and systems.

Lexus Battery Types

Lead-Acid Batteries

Lead-acid batteries are the traditional choice for the 12-volt battery in most vehicles, including many Lexus models. They're proven, widely available and effective at delivering the burst of power needed to start an engine.

Nickel-Metal Hydride (NiMH) Batteries

Nickel-metal hydride batteries have long been used for hybrid battery packs, including in earlier Lexus hybrids. They're known for durability in repeated charge and discharge cycles.

Lithium-Ion Batteries

Lithium-ion batteries are lighter and more energy-dense. Toyota uses them in plug-in hybrids and battery-electric vehicles, and some hybrids use them as well. The battery chemistry depends on the model and year, so check your owner's manual or ask our service team about your specific Lexus.

Seven Signs Your Lexus Battery May Be Failing

  1. Warning lights: A battery or charging system light on the dashboard can signal a problem.
  2. Slow engine crank: If the engine turns over slowly when you start the car, the 12-volt battery may be weak.
  3. Electrical issues: Dim headlights, a flickering display or malfunctioning accessories can point to low battery power.
  4. Battery age: A 12-volt battery typically lasts about three to five years, depending on climate, driving habits and usage, so an older battery is worth testing.
  5. Corrosion: White or bluish buildup around the terminals can interfere with the connection.
  6. Rotten egg smell: A sulfur smell can indicate a leaking battery and should be checked right away.
  7. Swelling or bulging case: A swollen battery case can be a sign of damage or overheating.

If you notice any of these signs, schedule a battery test. Our technicians can check the 12-volt battery and charging system, and for hybrids, the hybrid system as well.

How Long Does a Lexus Battery Last?

A conventional 12-volt battery generally lasts around three to five years, though heat, short trips and frequent use of electronics can shorten that. Hybrid batteries are built to last much longer. Lexus extended its hybrid battery warranty to 10 years or 150,000 miles on 2020 model-year hybrids, with other hybrid components covered for 8 years or 100,000 miles. Coverage varies by model and year, so ask us or see our guide to Lexus warranty coverage for details.

How to Replace a Lexus 12-Volt Battery

Because modern Lexus vehicles have sensitive electronics, and hybrids have high-voltage systems that can be dangerous, we recommend having a professional replace your battery. If you do plan to replace a standard 12-volt battery yourself, check your owner's manual first, since the location and procedure vary by model and some batteries are in the trunk or under the seat. In general, the process looks like this:

  1. Turn off the vehicle and remove the key or fob.
  2. Locate the battery and any cover over it.
  3. Wear gloves and eye protection.
  4. Disconnect the negative (black) terminal first.
  5. Disconnect the positive (red) terminal.
  6. Remove the hold-down bracket and lift out the old battery.
  7. Clean the tray and terminals.
  8. Install the new battery that matches your vehicle's specifications.
  9. Reconnect the positive terminal first, then the negative terminal.
  10. Start the vehicle and check that the electronics work. Some vehicles may need to relearn settings.

Dispose of the old battery responsibly at a recycling location or let our team handle it for you.

Everything to Know About Lexus Warranty in 2026

Buying a luxury vehicle means investing in quality that lasts. When you purchase a new or Certified Pre-Owned Lexus from us at Longo Lexus, understanding exactly what your warranty covers protects that investment and gives you confidence behind the wheel. We're proud to offer Lexus warranty coverage that provides multiple layers of protection designed to keep your vehicle running at peak performance while minimizing unexpected repair costs. Explore our new Lexus inventory to find the perfect vehicle backed by comprehensive warranty protection. Understanding Your Complete Lexus Warranty Coverage Every new Lexus comes with comprehensive factory protection that covers you from the moment you drive off our lot. The Lexus factory warranty includes several distinct coverage types that work together to protect different aspects of your vehicle. Your basic warranty shields you against manufacturing defects in materials and workmanship, while specialized coverage extends protection to critical systems like your powertrain and hybrid components. Here's how Lexus warranty coverage actually works in practice. Components that face the most stress receive extended protection periods. This layered approach means you're covered for what matters most, when it matters most. Understanding each coverage tier helps you make smart decisions about maintenance and future protection needs. New Vehicle Warranty Protection The Lexus new car warranty establishes the foundation of your vehicle's protection. Purchase a new Lexus from us and you'll receive bumper-to-bumper coverage for four years or 50,000 miles, whichever comes first. This comprehensive protection addresses virtually every component of your vehicle, from the advanced infotainment system to the climate control and beyond. Your powertrain gets separate, extended coverage lasting six years or 70,000 miles. This protects the engine, transmission, and drivetrain components that keep your Lexus moving smoothly. Hybrid owners benefit from even longer protection for their specialized systems. These overlapping coverage periods create a safety net that adapts to how different vehicle systems age and function. Bumper-to-Bumper Coverage The basic warranty covers repairs needed due to defects in materials or workmanship across nearly all vehicle systems. Your Lexus is protected against issues with the audio system, navigation, safety features, electrical components, and countless other parts. This coverage addresses the widest range of potential concerns during your first years of ownership. Some items fall outside this coverage. Regular maintenance items like oil changes, brake pads, and wiper blades that wear naturally through normal use aren't included. Damage from accidents, environmental factors, or improper maintenance also isn't covered. The warranty focuses specifically on manufacturing defects rather than wear items or external damage. Powertrain Warranty Protection Your powertrain warranty protects the heart of your vehicle. The engine block, cylinder heads, and internal parts receive coverage against defects. Your transmission, including the case, internal parts, and torque converter, falls under this protection. The drivetrain components that transfer power to your wheels are also covered, ensuring your Lexus delivers the performance you expect. This extended coverage period makes sense when you consider powertrain components represent the most significant potential repair costs. Having protection that extends beyond the basic warranty provides peace of mind during the critical years when your vehicle establishes its long-term reliability pattern. Hybrid System Warranty Benefits Lexus hybrid owners receive specialized protection for their advanced technology. The hybrid system warranty covers components unique to hybrid vehicles: the hybrid battery, battery control module, hybrid control module, and inverter with converter. For 2026 models and recent years, this coverage extends to eight years or 100,000 miles on the hybrid battery. Some newer Lexus hybrid models receive even more extensive protection, with battery coverage extending to 10 years or 150,000 miles. This demonstrates Lexus's confidence in hybrid technology and commitment to owners who choose environmentally conscious luxury. Additional Warranty Benefits Included with Every Lexus Beyond the core warranty protection, every new Lexus includes valuable additional benefits that enhance ownership. These supplementary coverages address specific concerns and provide services that keep your vehicle in optimal condition. Corrosion Perforation Protection Your Lexus includes protection against rust-through of body sheet metal for six years with unlimited mileage. This corrosion perforation warranty covers holes that develop from the inside out due to manufacturing defects in materials or workmanship. Surface rust or cosmetic corrosion isn't covered, but structural integrity is protected. This coverage proves particularly valuable in regions with harsh winters where road salt accelerates corrosion. The unlimited mileage aspect means high-mileage drivers receive the same protection as those who drive less frequently. LexusCare Complimentary Maintenance and 24/7 Roadside Assistance New Lexus vehicles include LexusCare complimentary maintenance covering your first two services. Your first service at six months or 5,000 miles and second service at 12 months or 10,000 miles include oil changes and multi-point inspections. Staying current with these services at our El Monte location helps maintain your warranty coverage and keeps your vehicle running optimally. Round-the-clock roadside assistance provides support for four years with unlimited mileage. Experience a flat tire, dead battery, lockout situation, or run out of fuel? Help is just a phone call away. Towing to the nearest Lexus dealership is included if your vehicle can't be driven. This service adds a layer of security that makes every drive more confident, whether you're commuting around Southern California or traveling cross-country. Lexus Certified Pre-Owned Warranty Benefits The Certified Pre-Owned Lexus warranty extends substantial protection to pre-owned vehicle buyers. Every Lexus Certified Pre-Owned vehicle undergoes a rigorous 161-point inspection performed by factory-trained technicians. Only vehicles under six model years old with fewer than 75,000 miles that meet strict condition standards qualify for the program. We provide bumper-to-bumper coverage for two years with unlimited mileage from the date of certified purchase. This coverage comes in addition to any remaining factory warranty on the vehicle. Your powertrain receives protection for six years or 70,000 miles from the original in-service date. Explore our Certified Pre-owned inventory to find quality vehicles backed by comprehensive warranty protection at exceptional value. CPO vehicles also include complimentary maintenance covering four factory-recommended services for two years or 20,000 miles, plus one year of roadside assistance. This comprehensive package makes Certified Pre-Owned Lexus vehicles an attractive option for buyers seeking luxury and reliability without the new car price tag. Extending Your Coverage with Lexus Vehicle Service Agreements When your factory warranty approaches expiration, Lexus Vehicle Service Agreements offer the opportunity to extend your protection. These plans allow you to maintain comprehensive coverage beyond the standard warranty period. Several plan levels are available, ranging from Powertrain Protection covering engine, transmission, and axle assemblies to Platinum Protection offering the most comprehensive coverage across multiple systems. Lexus Vehicle Service Agreements are designed specifically for Lexus vehicles and administered by the manufacturer. This means claims are handled through the same system as your original warranty, providing consistency and reliability. Coverage can extend up to 10 years or 125,000 miles from your vehicle's original in-service date. Purchasing a Vehicle Service Agreement before your factory warranty expires is typically more cost-effective than buying after coverage lapses. For owners planning to keep their Lexus long-term, these agreements provide budget protection against unexpected repair costs while maintaining the quality of authorized dealership service. Warranty Transferability Adds Long-Term Value The transferable nature of Lexus warranties significantly enhances your vehicle's resale value. Sell your Lexus before the warranty expires and the remaining coverage automatically transfers to the new owner at no charge. This benefit makes your vehicle more attractive to potential buyers compared to vehicles without transferable warranties or those from brands requiring transfer fees. Both the basic warranty and powertrain warranty transfer seamlessly. Even the hybrid system warranty transfers with the vehicle. This policy demonstrates Lexus's confidence in their vehicles' long-term reliability and commitment to all owners, not just the original purchaser. The transfer process is automatic and requires no special paperwork or fees. When ownership changes, the new owner simply needs to register with Lexus using the vehicle identification number to access warranty information and services. This simplicity, combined with the valuable coverage being transferred, often justifies a higher asking price when you're ready to sell or trade your vehicle.

Lexus Major Service

What Is Included in Lexus Major Service?

Owning a Lexus is synonymous with luxury, reliability, and top-tier performance. But like any vehicle, your Lexus requires routine maintenance to keep it running at its best. While minor services such as oil changes and tire rotations are crucial, more comprehensive care is sometimes necessary. That's where Lexus major service comes in. This essential service includes several detailed inspections, replacements, and adjustments to ensure your vehicle continues to deliver the performance you expect. Below, we'll explore what's included in a Lexus major service to help you understand its importance. Understanding Lexus Major Service Lexus major service typically takes place every 15,000 miles, alternating with the regular 5,000-mile interval services.  It helps prolong the life of your Lexus, prevent breakdowns, and ensure optimal performance. Lexus also offers personalized maintenance schedules for your specific model. Oil and Filter Change Changing the engine oil and oil filter is critical to any service. In a major service, our Lexus technicians drain and replace the oil with high-quality synthetic or standard oil, depending on your vehicle's requirements. They also change the oil filter to ensure no dirt or debris affects the engine's performance. Oil lubricates moving parts in the engine, prolonging engine life and keeping your Lexus running smoothly. Neglecting regular oil changes can lead to costly engine damage down the road. Brake System Check and Brake Fluid Replacement Over time, brake components wear down, and brake fluid absorbs moisture, which can reduce braking performance. Our team thoroughly inspects the entire brake system during a Lexus major service. This includes checking the brake pads, rotors, and calipers for wear and tear, ensuring you can brake safely and reliably. Tire Rotation and Wheel Alignment An important part of a major service is rotating the tires, which helps maintain even tread wear, prolonging their life span. We also inspect the wheel alignment to ensure that your Lexus travels in a straight line, preventing uneven tire wear and enhancing overall handling. Air Conditioner Filter and Engine Air Filter Replacement We replace the engine and cabin air filters at every major service interval. The engine air filter ensures that clean air flows into the engine for combustion, while the air conditioner filter improves air quality, saves energy, and prevents your air conditioner from malfunctioning. Spark Plug Replacement Spark plugs play a crucial role in the combustion process, igniting the air-fuel mixture in the engine. Worn spark plugs can cause misfires, reduce fuel efficiency, and affect engine performance. Replacing them at the correct interval ensures peak performance. A spark plug change is usually recommended at the 100,000-mile mark, but a spark plug could be the issue if you're having trouble starting your car or hear an unusual sound. In that case, a thorough check and a possible replacement are recommended. Fluids Replacement and Top-Up Our major service includes inspecting and replacing several essential fluids to keep your vehicle running smoothly: Transmission fluid: It ensures the smooth operation of the transmission system, preventing wear on internal components. Coolant: It maintains optimal engine temperature and prevents overheating. Differential fluid: It lubricates the gears in the differential. If not changed on time, the differential becomes noisy and can eventually fail, seizing the gears. Windshield washer fluid: Ensures that you have clear visibility at all times. Our service technicians will inspect, top up, or replace these fluids as necessary. Comprehensive Vehicle Inspection A major service includes a detailed inspection of your vehicle's core systems. These include the following: Exhaust system: Checking for leaks or damage that could affect performance and fuel consumption. Suspension system: Inspecting components such as shocks, struts, and springs for wear or damage. Battery health: Ensuring the battery is fully functional and testing its charge to prevent starting issues. Lights: Making sure all headlights, taillights, and interior lights are working properly. This comprehensive inspection aims to identify potential problems before they become serious and keep your Lexus in top condition. Lexus Service Professionals Our Lexus-certified technicians are trained specifically to work on Lexus vehicles and use genuine Lexus parts so everything works perfectly. They also follow detailed service checklists, thoroughly inspecting and servicing every part of your car. This ensures that your vehicle will continue to perform optimally, reducing the risk of breakdowns and maintaining resale value. Get Your Lexus Major Service Done at Longo Lexus Today From fluid replacements and engine inspections to tire rotations and safety system checks, Lexus major service is designed to keep your Lexus performing at its best for years to come.

Lexus Care

Basic Maintenance Guide for New Lexus Owners

As a new Lexus owner, it's important to understand the significance of regular vehicle maintenance. Properly caring for and servicing your Lexus will help extend its lifespan, ensure optimal performance, and maintain the highest levels of safety for you and your passengers. This comprehensive guide will cover essential maintenance procedures and their recommended intervals to keep your Lexus running smoothly for years. Oil Changes and Filter Replacements One of the most critical maintenance tasks for your Lexus is regular oil changes and filter replacements. The engine oil lubricates and cools the moving parts in your vehicle's engine, while the oil filter removes contaminants and debris. Over time, the oil breaks down and becomes less effective, and the filter can become clogged, leading to reduced engine performance and potential damage. Lexus recommends changing your vehicle's oil and filter every 5,000 miles or six months, whichever comes first. If you frequently drive in stop-and-go traffic, extreme temperatures, or dusty conditions, you may need to change your oil more often. Always use genuine Lexus oil filters and the recommended grade of oil specified in your owner's manual to ensure optimal engine protection and performance. Tire Rotation and Inspection Regularly rotating and inspecting your tires is essential for maintaining even tread wear, improving fuel efficiency, and ensuring a safe and comfortable ride. Uneven tire wear can lead to reduced traction, increased road noise, and a shorter lifespan. Lexus recommends rotating your tires every 5,000 to 10,000 miles or as specified in your vehicle's maintenance schedule. During tire rotations, it's also important to inspect the tires for any signs of damage, such as cuts, punctures, or bulges, and to check the tire pressure. Maintaining the proper tire pressure improves fuel economy and helps prevent premature wear and blowouts. Always use high-quality tires approved by Lexus to ensure optimal performance and safety. Brake Inspections and Replacements As your Lexus' braking system is one of its most critical safety features, it's essential to have your brakes inspected regularly and replaced when necessary. Over time, brake pads and rotors wear down from the friction generated during braking, reducing stopping power and increasing stopping distances. Lexus recommends inspecting your brakes every 5,000 to 10,000 miles or as specified in your vehicle's maintenance schedule. During a brake inspection, a certified Lexus technician will measure the thickness of your brake pads and check the condition of your rotors. If the pads have deteriorated to the minimum thickness or the rotors are warped or excessively worn, they should be replaced. Signs that your brakes may need attention include squealing or grinding noises, a soft or spongy brake pedal, or a vibrating steering wheel when braking. Always use genuine Lexus brake components for the best performance and safety. Battery Maintenance and Replacement Your Lexus' battery starts the engine and powers the vehicle's electrical systems. Over time, batteries lose their ability to hold a charge, leading to difficulty starting the engine or unexpected failures. To help extend the life of your battery, Lexus recommends having it inspected every 15,000 miles or 18 months. During a battery inspection, a technician will check the battery's charge level, inspect the terminals for corrosion, and ensure the connections are tight and secure. If your battery is over 3 years old or shows signs of weakness, it may be time for a replacement. Signs of a failing battery include slow engine cranking, dimming headlights, or the need for frequent jump starts. Always use a genuine Lexus battery for optimal performance and reliability. Scheduled Maintenance and Inspections In addition to the specific maintenance tasks mentioned above, following the comprehensive maintenance schedule outlined in your Lexus owner's manual is crucial. This schedule includes a variety of inspections and services at specific mileage intervals, such as fluid changes, belt replacements, and overall vehicle inspections. For example, Lexus recommends replacing your engine air filter every 30,000 miles, your cabin air filter every 15,000 miles, and your spark plugs every 60,000 miles. Regular fluid flushes and replacements, such as brake fluid, transmission fluid, and coolant, are also essential for maintaining your vehicle's performance and longevity. Having these services performed by certified Lexus technicians using genuine Lexus parts ensures your vehicle receives the highest quality care and attention. Routine Maintenance Tasks and Best Practices In addition to the scheduled maintenance and inspections, there are several routine maintenance tasks you can perform yourself to help keep your Lexus in top condition. These include: Checking and topping fluid levels, such as engine oil, coolant, and windshield washer fluid. Inspecting and replacing wiper blades. Checking and adjusting tire pressure. Cleaning and lubricating door hinges and locks. Replacing the cabin air filter to maintain fresh, clean air inside the vehicle. By staying on top of these routine tasks, you can help prevent minor issues turning into more significant problems. To get the most out of your Lexus ownership experience, you can also follow these best practices: Keep detailed records of all maintenance and repairs performed on your vehicle. Follow your Lexus' break-in period recommendations for the first 1,000 miles. Avoid overloading your vehicle, as this can strain the engine, suspension, and brakes. Address any unusual noises, vibrations, or performance issues promptly to prevent further damage.
