Owners of the Kia Sedona minivan most commonly complain of electrical issues. Faulty alternators are commonly reported, though unexplained power draws, faulty wiring harnesses and even electrical fires in the engine compartment have been reported as well. While the 2002 model is most affected, electrical problems appear endemic to almost every model year of the Sedona. Owners of 2015 Sedonas have complained of unexplained power draws that can leave the vehicle's battery drained when left overnight.
Unusual brake noise or vibration from the rear drum brakes and brake rotor wear leading to loss of stopping power and premature replacement of the brakes are other relatively common complaints reported by Sedona owners. The 2005 Sedona is most commonly affected by these issues. Noise from the rear brakes may present as a creaking or humming noise. Both noise and vibration during braking may accompany premature brake wear, though the two issues do not always occur together. Owners of affected vehicles often report that the brakes need to be replaced after less than 10,000 miles of use.
