2021 Lexus ES — Known Trouble Spots
The systems that tend to fail first on the 2021 Lexus ES, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.
Owners have reported premature failure of the 12V auxiliary battery, often within 2-3 years, sometimes leaving the car unable to start. This is more prevalent in hybrid models but can affect all variants.
The Lexus Remote Touch interface, while functional, can be clunky and distracting to use. Occasional software glitches, freezing, or unresponsiveness of the trackpad controller have been noted by owners.
