I have a 2006 Kia Sedona 2.9, I was driving on the motorway and heard a clanking noise which sounded as though something had 'fallen' off the underside of the car, a few moments later a similar noise about a mile up the road the car lost all power all the lights flashed up on the dash and i pulled over. RAC came out and said oil was all over the engine making it difficult to see what has happened so advised me to get towed to my garage. This I did. The garage inspected the car and said that they would need to replace the engine due to the 'damage' at a cost of £2,000-3,000! My husband phoned Kia and they asked to see the vehicle. Their report stated the following, 'Relayed in hole in the sump and metal lumps loose in sump, investigated and stripped off the sump found the balance shafts seized and sheared off the retained bolt, the crankshaft gear has torn teeth so requires replacement which involves crankshaft removal' I have had my car serviced as recommended, all be it not at a Kia Dealership as their labour rate is ridiculous, and had the cambelt changed in Dec. Kia won't cover it under warranty as the 7 year warranty doesn't apply to my vehicle, and they won't do it under a goodwill policy because I haven't had it services with them! I asked the aftersales manager, what I could have done to prevent this and he said there was nothing I could have done. The balance shaft seized due to either an oil blockage or the oil pump failing, (they can't check the oil pump because it is 'non existent', neither of these issues would show up as a fault on the dashboard panel. Therefore my argument is, if I can't prevent this from happening, by being advised there's a problem via the dash, or in a routine service, surely the car isn't fit for purpose, because if I was advised this problem could occur I would never have purchased the vehicle in the first place! I think this is fault on the Sedona but I don't know how to pursue this further; I have heard of Crank shaft pulley problems with other Kia models and wonder whether this is a similar fault, any experience from other members would be greatly received to help find out where I go from here currently being told £2,130.68 would solve the problem!
