Defect: Kia Motors America (KIA) is recalling certain 2020 Sedona vehicles. The battery positive (B+) terminal nut on the alternator may not have been tightened properly during assembly, possibly causing it to loosen over time.
Risk: If the alternator B+ terminal nut loosens, electrical arcing may result, increasing the risk of a fire.
Fix: Kia will notify owners, and dealers will inspect the alternator B+ terminal nut, tightening it as necessary, free of charge. The recall began August 14, 2020. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC192.
Service bulletins (64)
Technical service bulletins are repair instructions manufacturers send dealers for known issues. Unlike recalls, the fix is not automatically free — but naming the bulletin at the service desk can save diagnosis time and support goodwill repairs.
