Lexus NX 300h reliability & problems

Lexus has a peerless reputation for reliability and when things do go wrong they’re sorted in a fashion that leaves customers in no doubt they’ve been looked after. At least that’s what we keep being told by the responses to our Driver Power satisfaction survey, in which the Lexus NX finished a highly commendable sixth overall in 2018. In fact, the NX came out top of the 75 cars surveyed for build quality, with only 6.6% of owners reporting a fault in their first year of ownership. The Lexus brand was outright winner for satisfaction, too.

Given that the NX has been around for a few years now, and the fact that versions of Toyota-developed hybrid drivetrains are installed in 1.5 million vehicles every year, the reliability picture is reassuring to say the least.


A five-star Euro NCAP crash-test result is par for the course when you get to this end of the market (and indeed well below it) but the Lexus NX didn’t disappoint. It was awarded an 82% rating for adult and child occupants, with 69% for pedestrian protection.

The car comes with 14 airbags, including a knee airbag for the driver, while the Lexus Safety System+ includes automatic emergency braking, adaptive cruise control, blind-spot monitoring and lane-keeping assistance and chassis stability control. With optional 360-degree cameras and cross traffic-alert also in the mix, the Lexus NX wants for little when it comes to safety.
