Common Problems with the
2019–2021 Lexus ES

The 12V battery on modern Lexus hybrids can drain quickly if the car is not driven for more than a few days, leading to a completely dead car that requires a jump start or battery replacement. The issue is exacerbated by parasitic draw from the infotainment standby, keyless entry, and connected telematics systems.

ES models fitted with the panoramic sunroof can suffer from blocked drainage channels, leading to water ingress into the headlining and boot area. Additionally, the sunroof motor and tracks can become slow or noisy over time, particularly in cold weather when grease thickens.

The ES is a heavy saloon, and the front lower suspension arm rear bushes can soften or tear over time, leading to vague steering feel, a dull thump over potholes, and inner-shoulder front tyre wear. This is a common MOT advisory on higher-mileage UK cars.

Some ES owners report a barking or squawking noise when releasing the brake pedal, caused by the electronic brake actuator calibration. The sound is usually harmless but indicates the actuator pump is cycling excessively. If the actuator fails completely, repair costs can exceed £1,500.

Headlight beam pattern failures and washer nozzle misalignment are common MOT advisories on the ES. The headlamp units can suffer from cloudy lenses or failing HID bulbs, while the washer jets can become clogged or misdirected, reducing cleaning effectiveness in winter salt conditions.
