Reliability & safety Rating

3.5 out of 5

The SEAT Mii electric is a fairly simple car with relatively little to go wrong, so long-term reliability should be excellent. The Mii electric’s cousins, the Skoda Citigo and Volkswagen up!, have done well in recent years in our Driver Power surveys. In late 2019, the Mii Electric scored a three-star safety rating in the Euro NCAP crash test after it was retested under the updated rules.

SEAT Mii electric reliability

While the SEAT Mii’s electric powertrain is unproven, it should be reliable thanks to development in the Volkswagen e-up!. SEAT as a brand came 14th out of 30 manufacturers in our 2019 Driver Power survey: with owners praising infotainment, connectivity, and most importantly in the Mii electric’s case, the electric category. There have been a few reliability concerns among this year’s results, however. 


Despite the SEAT Mii electric being fitted with active safety features such as Lane Assist and Traffic Sign Recognition as standard, it wasn’t enough to retain the models original five star rating received in 2011. In 2019 the Mii electric was tested again earning a three star rating.

The three star safety rating is by no means poor with scores for adult and child occupants being 81% and 83 % respectively. However, given that the design of the Mii is almost a decade old, it’s unfair to compare its most recent result to new cars tested this year. It scored 55% in the safety assist category as well, thanks to a decent level of standard safety equipment including multiple airbags, stability control, anti-lock brakes, traction control and ISOFIX child-seat mounts.
