Kia Ceed GT Line Isg CRDI (2018)
2018 Kia Ceed GT Line Isg CRDI
CarHunch analysed 117 real MOT records for the 2018 Kia Ceed GT Line Isg CRDI. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2018 Kia Ceed GT-Line diesel is notably unreliable on first MOT attempt, with only 61.2% passing versus the UK average of 80%—a substantial gap that suggests systemic issues beyond random wear. The absence of dangerous defects (0%) is reassuring, but the consistent underperformance across 117 vehicles points to recurring mechanical problems rather than one-off failures.
At 54,000 miles median, these cars are low-mileage for their age, yet they're still failing MOTs at twice the rate of the typical six-year-old. The near-zero advisory count combined with low failure numbers per vehicle suggests failures are concentrated in specific systems rather than scattered across minor issues—if you're considering one, have a pre-purchase inspection focus on the diesel engine, exhaust system, and suspension components.
What to check before buying a 2018 Kia Ceed GT Line Isg CRDI
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.
