The Niro’s stunning Driver Power customer satisfaction survey result in its debut year should make rivals sit up and take notice, while the Kia brand scored well overall, too. The car's Euro NCAP crash-test score depends on whether you’ve got all the optional safety kit fitted or not, but a five-star rating applies if you do.

Kia Niro reliability & problems

The Niro seems unlikely to give owners much cause for concern, especially in the light of its amazing entry into our 2018 Driver Power Survey, where it finished second overall out of 75 cars on sale in the UK. The feedback wasn’t related only to reliability, but across the board – so it’s a ringing endorsement of the Niro, in fact.

With tried-and-tested technology in terms of engine and electronics, there’s no reason to expect problems with the hybrid’s battery or motor to reduce those satisfaction levels later on. And of course with a seven-year warranty tucked into their back pocket, owners have every right to be reassured about their purchase.

The Kia brand did pretty well in the 2018 Driver Power survey, too, ranking eighth out of 26 competing manufacturers and ahead of several key rivals including Toyota and SEAT.


It’s a shame you need to purchase the Kia Niro 4 trim level to get automatic emergency braking (AEB). If your Niro is so-equipped, it boasts the maximum five-star Euro NCAP crash-test rating. Without it, the car only get four stars, but you can always add it as an optional extra to the lower-spec models for a few hundred pounds.

Unfortunately, you can’t spec the Niro 4’s blind-spot monitoring and rear cross-traffic alert on the cheaper versions.

In all other respects, the Niro does well on the safety front. It comes with all the usual systems like anti-lock brakes and stability control, hill-start assistance and even lane-keeping assistance as standard on all trim levels. There are also seven airbags and ISOFIX child-seat points.
