Problem overview

Some Kia Sorento owners report experiencing issues with the brake light and battery light illuminating after an alternator replacement, even when the vehicle appears to be running fine. These warning lights may indicate a faulty alternator that is not generating electricity properly, or a failing regulator within the alternator affecting the charging system. Additionally, a blown fuse can also keep the battery/charging light illuminated despite a new alternator being installed. The illuminated brake light may signal a problem with the braking system, such as low brake fluid levels due to worn-out brake pads. It is recommended that owners have a qualified automotive technician inspect the vehicle to diagnose the underlying issues, as ignoring these warning lights could lead to serious problems with the vehicle's electrical and braking systems.
