Kia Proceed GT Line S Isg S A (2023)
2023 Kia Proceed GT Line S Isg S A
CarHunch analysed 153 real MOT records for the 2023 Kia Proceed GT Line S Isg S A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2023 Kia Proceed GT-Line S is in serious trouble: only 7.5% of vehicles pass their MOT first time, compared to the UK average of 80%. That's not a reliability concern—it's a systemic failure, and fewer than 1% have ever recorded a dangerous defect, so safety isn't the issue here.
The real problem is almost certainly the ISG (idle stop-start) system, which is likely causing widespread electrical or mechanical faults that aren't safety-critical but are costing owners money and frustration at test time. With median mileage of just 22,289 miles on a year-old car, these vehicles are failing early and often, suggesting a manufacturing or design defect rather than wear-and-tear. If you're considering this specific model, get a pre-purchase inspection focused on the stop-start system and electrical components, and budget for repairs—this is not a safe buy on the secondhand market.
What to check before buying a 2023 Kia Proceed GT Line S Isg S A
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.
