Kia’s renowned seven-year/100,000-mile warranty is one of the biggest attractions for the Niro PHEV over the equivalent Toyota Prius, which comes with a five-year cover.

While the Niro’s clever hybrid powertrain is new, plenty of other components in the car are found elsewhere in the Kia range and so have been well proven.

The Niro also comes with plenty of safety equipment as standard, including autonomous emergency braking and lane-keeping assistance.

Kia Niro PHEV reliability & problems

The Kia Niro made an incredible Driver Power ownership survey debut in 2018, ending up in second place out of 75 cars, with an overall satisfaction score of over 93%.

Owners praised the car’s infotainment system (which itself ranked first for user-friendliness), interior, seats, comfortable ride and safety features. Only the boot – which some owners thought a bit small – and performance didn’t quite come up to some owners’ expectations.

Kia as a brand performed well in the same survey, finishing eighth out of 26 manufacturers. That put it well ahead of its Korean counterpart Hyundai (15th), as well as rivals including SEAT (14th), Toyota (12th) and Suzuki (11th).


The Kia Niro received a 'dual rating' from Euro NCAP, but the good news is that the PHEV has all the features that earned the car a maximum five-star rating.

That includes autonomous emergency braking (which can automatically apply the brakes to avoid a collision), adaptive cruise control (which maintains a safe distance from the car in front), lane-departure warning and lane-keeping assistance (which automatically steers you back into your lane if the car starts to wander).

A 2019 upgrade added stop-and-go functionality to the Niro PHEV's adaptive cruise control; it can now bring the Niro to a stop if traffic slows to a halt, and then get the car back up to speed when the car in front moves off.

Lane-following assist has also been added. This tracks vehicles in front of you in traffic and detects road markings to keep the Niro in its lane on the motorway, operating between zero and 81mph.
