Lexus UX problems (2018–today)
The only engine of the Lexus UX that we have documented, the 2.0 and 2.5 Hybrid, has no high or critical severity faults in the versions it is fitted to. Our verdict for the version it is fitted to: «With caution».[1]
Outside the engine: Apart from the hybrid system, the Lexus UX (from 2018) appears in the sources mainly through recalls: the eCall (three campaigns between 2019 and 2023), the software and camera housings, the brake servo pump on the UX 250h from May 2019 and the heating on the UX 300e. Auto Express considers it probably reliable, Polish owners rate it highly and the ADAC has no reported defects; no repair costs have been published.[2][3][4][5][6][7][8][9][10][11]
Lexus UX rating: acceptable reliability
Calculated using only 5 documented faults and their sources: the most serious and frequent faults weigh more. Limited evidence: it is based on few sources or few documented faults, so it is not included in the rankings. Having few documented faults does not mean it is reliable: it may simply be little studied. One of this car's engines has no documented faults in the versions it uses, but there aren't enough sources to call it reliable either, so it doesn't count towards the engine score.

Documented engine
The first label is the most serious fault affecting that engine in this car; the second, our verdict for the versions it is fitted to. Each engine's risk index is calculated only from the faults that affect this car (how we calculate it). We only show engines we have documented with sources: if yours does not appear, we have not analysed it yet. View all engines
Outside the engine
9 recalls and campaigns documented, the latest: DVSA R/2025/467 (ref. 5GG61 / 25SD-108): reprogramming of the parking assist unit. See the campaigns for the Lexus UX

With cautionWe have found no specific documented faults for the UX 250h with this engine. Given the scarcity of published information and that it shares the engine with the rest of this family, it is worth applying the same checks as on the Corolla or C-HR (fuel pump campaign, 12 V battery condition), although there is no confirmation that the pump campaign affects it.[1]

Faults of the Lexus UX outside the engine
Suspension, brakes, tyres, electronics and the rest of the car. They occur with any engine.
Electronics and infotainment
- Medium severityFrequency: OccasionalElectronics and infotainmenteCall system failure: communications module (DCM) not activated or failing to restartYes: the UX has had three eCall recalls between 2019 and 2023: a system not activated from the factory, a system that might not work when needed, and a communications module (DCM) that left eCall out of service by not restarting after a software fault.
- Medium severityFrequency: OccasionalElectronics and infotainmentFrozen rear camera image due to a software fault in the parking assist unitA Safety Gate alert from November 2025 includes the UX: the parking assist unit's software can freeze the rear camera image when you select reverse shortly after starting, or stop it appearing if the car is switched off and on again within a short time. The fix is a software update.
- Medium severityFrequency: OccasionalElectronics and infotainmentPoorly welded camera housings: water ingress and loss of imageA Safety Gate alert from July 2024 states that the camera housings on several Lexus and Toyota models, including the UX built between January and August 2023, can come apart under stress because of an incorrect weld, letting water in and causing a short circuit, with loss of the front or rear image.
