Kia Proceed GT Line Isg (2023)
2023 Kia Proceed GT Line Isg
CarHunch is tracking 1,707 2023 Kia Proceed GT Line Isg vehicles on UK roads. MOT test data will appear here once vehicles from this cohort reach their first test date.
This 2023 Kia Proceed GT-Line ISG is a reliability nightmare at first MOT: only 5.4% pass on the first attempt versus the UK average of 80%, meaning 19 out of 20 fail their initial test. The good news is dangerous defects are vanishingly rare at 0.4%, so failures are fixable rather than safety-critical.
At an average mileage of 28,883 miles for a one-year-old car, these vehicles are running normally for their age, yet the near-total first-time failure rate suggests a systemic build or setup issue rather than owner neglect. Before buying one, insist on a pre-purchase inspection by an independent mechanic familiar with Kia's ISG (integrated starter generator) system, since whatever's triggering these failures—likely emissions, electrics, or hybrid-specific components—needs identifying before you inherit the repair bill.
We have 1,707 2023 Kia Proceed GT Line Isg vehicles on record but don't have enough MOT test data to show reliable statistics for this cohort.
What to check before buying a 2023 Kia Proceed GT Line Isg
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
