On the 2017-2018 SEAT Arona, on the rear bench, the centre seatbelt buckle sits slightly higher than the left-passenger buckle. Under a sharp lateral manoeuvre (e.g., a quick lane change) with three rear occupants, the centre buckle stalk can overlap and depress the over-sensitive release button of the left buckle, causing the left rear belt to unfasten unintentionally. The buckles were Takata-sourced. This led to a formal DVSA/EU recall in 2018 affecting roughly 31,000 SEAT Arona and Ibiza cars in the UK (plus ~45,000 VW Polos). VW initially offered an informal cable-tie fix that the DVSA rejected; the permanent remedy fits a plastic spacer in the double buckle.

Common Symptoms

  • Rear left seatbelt unfastens on its own
  • Belt releases during cornering/lane change
  • Centre buckle interferes with left buckle

How to Fix

Have the recall (SEAT/DVSA seatbelt campaign) carried out free at a dealer — a plastic spacer is fitted into the rear double-buckle to prevent unintended release. Until fixed, owners were advised not to use the centre-rear seat. Verify completion via VIN recall lookup.

Typical repair cost:$0 - $0

On the 2017-2018 SEAT Arona, the UK DVSA recall results for 2017 and 2018 SEAT Arona vehicles list campaign R/2019/039. The record says handbrake lever travel can increase because the adjuster nut moves. The public recall page does not publish build dates and does not substantiate the frozen "early build" trim label; model year alone does not prove inclusion, so a VIN or recall check is required for a particular Arona.

Common Symptoms

  • Handbrake lever travel increases from its previous position

How to Fix

Check the VIN with SEAT or the applicable national recall service. For a vehicle included in R/2019/039, the official remedy is to readjust the handbrake assembly and fit a locking device to the nut; the DVSA page says recall work is provided without charge. Do not buy a handbrake cable, caliper or adjuster from this page; recall inclusion and the required repair must be confirmed from the VIN.

On the 2017-2022 SEAT Arona, the Arona's brake bias is heavily front-biased, so the rear discs do little work and corrode quickly — accelerated by parking with the electronic parking brake applied and by rain/road salt. Owners repeatedly report heavily rusted, pitted or grooved rear discs at only 2-4 years old and as little as ~4,000-20,000 miles, sometimes failing MOT or causing grinding/binding. A related handbrake-cable swelling/splitting issue can partially seize the rear calipers. Low-mileage town-driven cars are worst affected.

Common Symptoms

  • Rusty/pitted rear brake discs
  • Grinding or scraping from rear
  • Rear brake binding/seized
  • MOT advisory or failure on rear discs
  • Corrosion visible at low mileage

How to Fix

Replace corroded rear discs and pads (and seized handbrake cables/calipers where applicable). Mitigate recurrence by performing periodic firm braking to scrub the discs, and where safe parking on level ground without the electronic parking brake. Specify better-quality discs on replacement.

Typical repair cost:$180 - $450
