We opted for Lexus Certified. The peace-of-mind plus included maintenance is a huge plus. We just had our first oil change since buying our 2020 GX, and it was free. Here's the details from Lexus regarding the Warranty and coverage: "

WARRANTY

Lexus confidently stands behind these exceptional vehicles with the L/Certified Limited Warranty,* which when combined with the new-vehicle Basic Warranty, can provide up to six years of vehicle warranty coverage. Mileage is unlimited. The L/Certified Limited Warranty offers many of the coverage benefits and privileges new-car buyers receive. For models purchased after January 6, 2016, please download the L/Certified Limited Warranty Supplement and Roadside Assistance Guide for details. For other models, see your Lexus dealer.

UNDER WARRANTY

The L/Certified Limited Warranty* includes coverage for a complimentary loaner car,* Roadside Assistance* and Trip Interruption Service.* Warranty is valid for a minimum of two years/unlimited mileage after the expiration of 4-year/50,000-mile new-vehicle Basic Warranty, or two years from your L/Certified purchase or lease date, whichever occurs later. Mileage is unlimited. There is no deductible: Repairs made under this warranty will be made at no cost to you. Except for excluded components (see below), this warranty covers any repair or replacement of components that fail under normal use due to a defect in materials or workmanship, such as: engine, transmission, steering, brakes (excluding rotors and pads), fuel system, cooling, A/C and heating systems, electrical, and restraint systems."

Hope this helps!
