Kia Sedona MOT Failures
An analysis of 184,205 real DVSA MOT tests on the Kia Sedona — what fails, how often, and how that compares to every other car on UK roads. Generations covered: YP (1999–2006), YP2 (2006–2014).
Where the Kia Sedona fails its MOT
The single biggest MOT failure point on the Kia Sedona is suspension component damaged or corroded — this model is 32 times more likely to fail on this item than the average car on UK roads. That makes it a significant weak point for anyone buying or owning this model. Across 184,205 MOT tests, 7.08% of all Kia Sedona tests recorded this as a failure.
Suspension failures typically mean worn bushes, drop links, or dampers. These affect handling and tyre wear. Budget £150–£400 per corner at an independent garage for full suspension overhaul.
Other notable weak points include power steering fault (76x the fleet average), body panel damage (35x the fleet average), seat mounting fault (132x the fleet average), and abs fault (20x the fleet average). These ratios compare the Kia Sedona's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.
The failures span 6 categories: Suspension, Steering, Bodywork, Seatbelts & Airbags, Brakes and others. If you're inspecting a Kia Sedona before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.
How failures change with mileage
The Kia Sedona's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.
Under 60,000 miles
At this mileage, most failures are either design-related or caused by age rather than wear. Components like bushes and drop links may not have been replaced yet, and original-fit parts can deteriorate even on low-mileage cars that spend a lot of time sitting.
For the Kia Sedona specifically, the DVSA data shows the most common failures at this mileage are seat mounting fault (132x the average) and power steering fault (76x). significant brake effort recorded with no brake... (36x) and body panel damage (35x) also appear frequently.
60,000 to 100,000 miles
This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.
For the Kia Sedona specifically, the DVSA data shows the most common failures at this mileage are power steering fault (25x the average) and body panel damage (20x). track rod ends worn (16x) and emissions failure (14x) also appear frequently.
Over 100,000 miles
High-mileage cars accumulate failures across multiple systems. The key question isn't whether things will need doing — they will — but whether the car has been maintained well enough to keep on top of them. Look for a consistent service history and recent MOT passes with minimal advisories.
For the Kia Sedona specifically, the DVSA data shows the most common failures at this mileage are suspension component damaged or corroded (22x the average) and abs fault (20x). suspension ball joints worn (17x) and power steering fault (15x) also appear frequently.
The shift from seat mounting fault at lower mileages to suspension component damaged or corroded at higher mileages is typical — early failures tend to be design or factory-related, while high-mileage failures reflect accumulated mechanical wear. A car that's been well maintained will usually dodge the worst of both.
Known issues beyond the MOT
An MOT only tests roadworthiness at a single point in time — it won't catch developing faults, intermittent problems, or issues that haven't yet reached the failure threshold. These are the issues that Kia Sedona specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Brake binding and calliper seizure Dangerous
Brake callipers on the Sedona are prone to seizure, causing significant brake effort to be recorded even when no brake is applied - occurring at 1058.0 times the national fleet average. Affects YP, YP2; typical independent garage repair cost is £200–£400.
Power steering system failure Major
The hydraulic power steering system on the Sedona suffers from chronic fluid leaks and pump failure at a rate 45 times higher than the national fleet average. Affects YP, YP2; typical independent garage repair cost is £800–£1,200.
Suspension component corrosion and wear Major
The Sedona suffers from premature suspension component failure at rates significantly above the national average, with bushes and joints wearing at 228.9 times the fleet average and structural components corroding at 228.9 times the average rate. Affects YP, YP2; typical independent garage repair cost is £300–£800.
Engine oil leaks and head gasket failure Major
Both diesel engines in the Sedona range are prone to head gasket failure and various oil leak issues. Affects YP, YP2; typical independent garage repair cost is £1,500–£3,000.

What to check before buying a Kia Sedona
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Kia Sedona:
Suspension — check for suspension component damaged or corroded, coil springs broken. Steering — check for power steering fault. Bodywork — check for body panel damage, towbar fault. Seatbelts & Airbags — check for seat mounting fault.
Beyond the MOT items, ask specifically about brake binding and calliper seizure and power steering system failure. These won't show up on a standard MOT but can be expensive to fix — repairs start from £200. A specialist pre-purchase inspection is worth the investment on this model.
Always check the car's full MOT history for patterns — recurring advisories often become failures within 12 months. And verify the service history to confirm maintenance has been kept up to schedule. Enter any reg into our free car check to see the complete picture.
