Used Seat Mii 2012-2019 reliability

The Mii is a city car, which means there's potential for heavy clutch use, so check the clutch has a smooth action with no slippage. If there are any such issues, it could mean the clutch needs to be replaced – a potentially costly job.

Check for bumps and scrapes to the bumpers and bodywork, because these will all cost money to put right.

Not all Miis came with sat-nav. On earlier cars, it's a removable unit that sits on top of the dashboard. Some will have gone without, while some high-spec and special-edition Miis had one fitted as standard, so it's worth contacting your local Seat dealer to find out whether your prospective purchase came with it. If it did, check that the previous owner has left it in the car.

The exposed paintwork in the boot of the Mii can easily be damaged by sharp objects. This is due to only part of the boot floor being covered by carpet.

Also check that the DAB radio, if fitted, works. The unit might not be covered under warranty if it stops working or the screen gets scratched.

Towing eye

The welding of the towing eye in the vehicle toolkit might fail if the car is towed and affects cars produced between 1 October 2015 and 31 November 2017. Most should have had a new towing eye by now, but do check this with your local Seat dealer.

Manual child lock

The child lock can disengage without the driver knowing, with the potential for occupants being able to open the door from the inside and get out of the car. This recall involves Miis made between 25 November 2015 and 14 April 2016.

Side airbags

Some cars might have been fitted with airbag control units that weren't programmed correctly, with the potential for the system to not recognise any potential faults with the airbag system and warn the driver of them. This applies to Miis produced between 14 January 2013 and 19 March 2013.

Driver's airbag

The driver's airbag might not deploy correctly on cars made between 12 June 2013 and 15 June 2013. It only affects a small number of Miis, but you should still contact your Seat dealer to check whether your car is affected by this recall.

Seat as a brand seems to have slipped down the rankings in the most recent What Car? Reliability Survey, ending up in 15th out of 32 manufacturers.

There wasn't enough data to include the Mii individually, but the near-identical Skoda Citigo and Volkswagen Up finished third and 10th respectively out of 28 cars in the small and value car class, so the Mii should be a pretty dependable choice.
