The 2019-2020 Lexus UX models have a low-pressure fuel pump that can fail or seize, causing the engine to stall or fail to start. A mid-drive stall causes sudden loss of motive power and may require a tow. This issue was covered by NHTSA recall 20V012 and the dealer remedy was free, so an out-of-pocket repair price is not supported.
Early 2020 UX 250h models have reports of the 12-volt auxiliary battery draining, especially after the car sits for a while, which prevents the hybrid system from waking and can lead to a no-start. This is the conventional accessory battery, not the high-voltage traction battery. The sources do not provide a defensible replacement cost, so no repair price is supported.
The 2020 Lexus UX 200, the non-hybrid 2.0 liter model, can show delayed or hesitant throttle response at low speeds, especially in stop-and-go traffic. The evidence points to an ECU programming calibration as the cause, so it is a driveability annoyance rather than a safety failure. No repair cost is supported by the provided research.
The Remote Touch touchpad on 2019-2022 Lexus UX models can cause cursor lag, unresponsiveness, incorrect tracking, or complete pad failure, which makes navigation, audio, and climate controls frustrating to use. This issue is reported on 2019 models and the interface design remained through 2022. The 2023 refresh replaced the touchpad with a touchscreen, but research does not give a repair cost.
First-year 2019 Lexus UX models have reports of windshield cracking without an obvious stone impact, sometimes starting near the edges. This can obscure visibility and require windshield replacement, but the frequency is not quantified in the provided research. The sources do not include a defensible replacement price, so no repair a price is listed.
The 2019 Lexus UX can show intermittent rear-camera failures such as a blank, frozen, or delayed image when reversing. This can reduce rear visibility and is part of early electrical glitch reports on first-year cars. The research does not provide a repair estimate.
