Lexus NX (Mk2) Problems by Year

The second-generation Lexus NX represents a monumental leap forward for the brand's mid-size SUV, finally addressing the technological shortcomings of its predecessor. Riding on the TNGA-K platform, it introduced the critically acclaimed "Lexus Link Pro" infotainment system, banishing the dreaded trackpad in favour of a crisp, responsive touchscreen. It also brought plug-in hybrid technology to the Lexus lineup for the first time with the NX 450h+, alongside the immensely popular and highly efficient NX 350h self-charging hybrid. On the road, the Mk2 NX offers a beautifully judged balance of ride comfort and composure. It is a deeply relaxing car to drive, insulating its occupants from the stress of UK traffic with excellent soundproofing and a seamless transition between electric and petrol power. The interior materials are first-rate, and the cabin introduces novel features like "e-latch" electronic door handles. While it still isn't quite as engaging on a winding B-road as a BMW X3, the NX trades outright dynamism for a sense of serene luxury that resonates strongly with premium SUV buyers. Despite Lexus’s legendary reliability record, the Mk2 NX has experienced a few notable teething issues. The most widely reported problem in the UK is the premature failure or rapid draining of the 12V auxiliary battery, which can leave the car completely unresponsive if parked for just a few days. Furthermore, AWD hybrid models share the "Cablegate" vulnerability seen on other Toyota/Lexus models, where the high-voltage cable connector to the rear electric motor can corrode due to exposure to road salt. While a revised cable shield has mitigated this, buyers should ensure any outstanding software updates and hardware checks have been completed by a main dealer.
