Thankfully, the car battery is covered under the Lexus warranty. Coverage for your battery falls under the four-year, 50,000-mile basic warranty for new cars, which is among the best in the business.
If you decide to purchase a hybrid vehicle, you’re covered for even longer. Every new Lexus hybrid vehicle is covered by an eight-year, 150,000-mile hybrid warranty—whichever comes first. This will pay for a replacement battery if it fails within this time frame, which is a godsend considering that hybrid batteries can cost around $5,000.
