Lexus owners love their cars, and safety is a strong suit of the Lexus UX

Carbuyer Rating

3.9 out of 5

Reliability & safety Rating

4.5 out of 5

Lexus has forged an enviable reputation for reliability and customer care and these are among the brand's key attributes. The Japanese premium brand also enjoys a reputation for technology and sophistication, to which the UX's long list of standard and optional safety equipment lends credence.

Lexus UX reliability

Lexus couldn't have fared better in our 2020 Driver Power owner satisfaction survey: it finished ahead of every other brand among the 30 surveyed.

Owners rated their cars strongly on all aspects of their performance, from engines and gearboxes to fuel consumption and running costs. Reliability was praised, too, even though 9% of survey participants reported at least one fault with their car in the first year. In only one category was there widespread disappointment: owners find the brand's infotainment systems fiddly to use and lacking in features.


Safety technology is definitely a Lexus strong suit and the UX offers the brand's Lexus Safety System+ package. This includes autonomous emergency braking and active cruise control with pedestrian recognition, lane-keeping assistance and lane-departure warning, road-sign recognition, automatic headlights and auto-dipping headlights.

There's a semi-autonomous mode for driving in stop-start traffic at up to 18mph, and the active cruise control can be set to automatically comply with speed limits posted on roadside signs. Optional Parking Support looks out for traffic crossing when you're pulling out of a parking space, and there's a rear-view camera to aid manoeuvring.

Euro NCAP awarded the UX five stars when it tested the car in the spring of 2019. It scored an impressive 96% for adult occupant protection, as well as 85% for child occupant protection and 77% for safety assist.

In addition to the Premium Pack, a Lexus Driver Assist Pack can be added for £750, bringing blind-spot warnings and rear cross traffic alerts with automatic braking. Lexus claims these significantly reduce the risk of a collision by giving the driver better awareness of their surroundings and approaching hazards.
