2021 Kia Sedona Electrical Problems

Your headlights or exterior lights are going out every six months without a clear cause. Additionally, your car shudders or sputters when you accelerate, which feels like it could be related to belt slipping or transmission issues, but multiple shop visits haven't identified the root cause. This problem has persisted since you bought the car. Resolving this will likely require a thorough diagnostic to identify whether it's an electrical, belt, or transmission-related issue.

Your engine started making a knocking sound while driving on the highway in a construction zone with no safe place to pull over. The knock sensor warning light didn't come on, so you had no advance warning of the problem. Your car was towed to the dealership, but Kia declined to take responsibility since there's currently no recall for this issue. The knock may indicate an engine timing or fuel quality problem that needs diagnostic testing and possible engine repair.
