Have 2004 Sedona LX 9,000 miles and have hollow thumping noise in front end. Very bad at slow speeds around 30 mph. Had van in on 01-10-05 for problem had called Kia before going on 12-27-04 and got ref# for complaint. While at dealer Zone rep E-mailed them about my problem. Service manager showed me e-mail and per Kia they say that this noise is inherernt to this vehicle,they are aware of the noise but there is no fix for problem at this time. This info is printed out on my copy from dealership. You will not find a TSB for this so stop looking. TSB's are for tech's so they can FIX a problem! Per Kia no fix is availiable at this time so no TSB!!!
