Common Problems & Reliability
The 2007 Kia Sedona has 2 known issues. 1 of these are classified as serious faults that could be expensive to repair. 1 are moderate concerns worth inspecting before purchase.
Rear Auxiliary Heater Underbody Pipe Corrosion and Coolant Loss
SeriousThe Sedona features a dedicated rear passenger heater matrix supplied by metal coolant lines routed along the underside of the vehicle chassis. Exposed directly to road salt, grit spray, and damp UK winter conditions, these steel pipes corrode and eventually develop pinhole perforations. Coolant leaks out rapidly beneath the car, leading to sudden engine overheating and potential cylinder head gasket failure if the driver fails to notice the dropping coolant gauge. Replacing the metal lines with upgraded rubber hoses or aluminium lines is a well-known specialist fix.
Symptoms: Puddle of pink or green coolant on the ground beneath the centre or rear floorpan of the car, Loss of cabin heating output accompanied by rising temperature gauge reading...
Est. repair cost: £250–£550
Electric Power Sliding Door Cable and Actuator Failure
ModerateHigher-specification second-generation Sedonas (such as the TS and 3 trim grades) feature electrically operated power-sliding rear side doors. The drive mechanisms rely on steel tension cables, plastic pulleys, and microswitch sensors located within the rear quarter panels and sill runners. With age, road grit accumulates in the lower floor tracks, door seals stick, and the steel drive cables fray or snap. When this occurs, the electric motor jams, leaving the door unable to open or latch shut automatically, necessitating manual override or expensive cable kit renewal.
Symptoms: Sliding door beeps and reverses direction midway through opening or closing, Grinding or whining noise from the rear quarter panel when pressing the door button...
Est. repair cost: £200–£600
Buying Tips for the 2007 Kia Sedona
- Inspect the operation of both sliding side doors (electric on high-spec models) for smooth gliding on tracks and secure latching
- Check the condition of the 2.9 CRDi engine oil and cooling system, looking for signs of oil contamination or cooling hose degradation
- Inspect the rear subframe, chassis outriggers, and brake pipe runs for road salt corrosion that can lead to MOT structural failure
- Confirm that the front and rear heating and ventilation blowers both output hot and cold air, as rear underbody coolant pipes are prone to leaking
- Test the manual clutch pedal effort and check for shudder, as the Sedona heavy kerb weight puts considerable strain on the driveline
