2008 KIA Sedona 2.9L Diesel · PE08 FDX

Structural corrosion and recurring component wear define the mechanical profile of this Kia Sedona, which successfully passed its latest MOT on 24 December 2025 following a failure for excessive black smoke and wiper inefficiency. While the vehicle has maintained a consistent testing cadence, the recent emergence of corrosion advisories affecting both the front and rear suspension systems, alongside a deteriorating exhaust, suggests that the vehicle is now entering a phase where age-related degradation is becoming more prominent. The progression from minor play in steering components in 2023 to more significant failures in subsequent years indicates that the chassis and drivetrain are requiring more frequent intervention to remain compliant with roadworthiness standards. Accumulating 146,920 miles over eighteen years results in an average annual usage of approximately 8,162 miles, a figure that is consistent with typical domestic operation for a vehicle of this size and class. This steady rate of use generally avoids the issues associated with prolonged periods of inactivity, such as seized brake calipers or perished rubber seals, though it has clearly contributed to the gradual fatigue of high-wear items. The absence of significant gaps in the MOT history confirms that the vehicle has remained in regular service, meaning the current mechanical state is the result of continuous operation rather than neglect during long-term storage. Prospective buyers should prioritise a thorough inspection of the suspension and exhaust systems, as these were explicitly flagged as corroded in the most recent test. During a test drive, listen carefully for any metallic rattling or knocking sounds when traversing uneven road surfaces, which could indicate that suspension bushes or mounting points have reached the end of their service life. Given the history of track rod end play, pay close attention to the steering feel; any vagueness, wandering at speed, or vibrations through the steering wheel could point to further wear in the steering linkages or ball joints that may require immediate replacement. The record of black smoke during acceleration, which necessitated a rectification in late 2025, warrants a cautious approach to the engine and fuel system. Observe the exhaust output during a cold start and under load; excessive smoke can be indicative of issues with the fuel injectors, turbocharger, or exhaust gas recirculation system, all of which are common areas of concern for high-mileage diesel engines of this vintage. Ensure the vehicle pulls cleanly under acceleration without hesitation, and verify that the brake pedal feel is firm and consistent, as the previous advisories regarding thin brake pads and worn pedal rubbers suggest that the braking system has been subject to significant wear and may require a comprehensive overhaul to ensure future reliability.
