Lexus RX 450h reliability & problems

There’s no doubt the Lexus reputation for reliability is one of the best in the car business – in fact, it’s hard to see it being bettered. In our 2018 Driver Power satisfaction survey, the RX was rated a highly impressive fifth overall, which is a tribute to the model’s build quality, fit and finish and satisfying ownership experience. However, the RX ranked a less impressive 18th in the survey on the specific question of reliability, with trim issues being most often raised as causing problems. That said, Lexus also finished first out of 26 manufacturers for overall customer satisfaction, which speaks volumes about the attentiveness of the Lexus aftersales network in the event that problems do arise.

Safety

As you’d expect from an expensive luxury car, the Lexus RX 450h comes laden with safety kit and has also performed very well in the Euro NCAP independent crash tests. Its roster of 10 airbags helped it to score an impressive 91% for adult occupant protection and 82% for child protection, on its way to a predictable five-star overall result.

As well as the inherent structural safety of driving a big, heavy SUV, the electronics are pretty advanced, too. Adaptive cruise control, traffic-sign recognition, plus lane-keeping assistance and cross-traffic alerts are all on the spec sheet or options list, while a tiredness alert, head-up display and 360-degree cameras help keep you focused on the task at hand.

If things do go wrong, a pre-crash safety system scans the road ahead for cars and pedestrians and autonomous braking is activated if the RX thinks you’re not taking fast enough action to avoid a crash.
