2020 Lexus UX score: good reliability
Calculated using only 1 documented fault and its sources: the most serious and frequent faults weigh more. 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.

We 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]
There are no documented 2.0 and 2.5 Hybrid faults that affect 2020 cars.
