An airbag light that stays on
On a 2021 Kia Sorento (MQ4), the airbag warning light shows for roughly 6 seconds after the ignition is switched on, then goes dark. A light that stays lit past those seconds, or reappears with the car in motion, signals a fault in the supplemental restraint system (SRS). We remove any add-on fitted on an airbag part or its wiring, and the maker's dealer repairs the SRS.

A flat battery after parking
The 2021 Kia Sorento (MQ4) detects battery self-discharge from over-current drawn by add-on devices, such as a dash cam running while parked. We move such a device to a feed that switches off with the ignition, or remove it.

A fuse that blows again
Kia states that a replacement fuse which blows again on the 2021 Sorento (MQ4) indicates an electrical problem. We follow the add-on circuit back to the short or overload, then repair or remove the wiring behind it.

Static from the speakers
Electronic devices plugged into the power outlet of a 2021 Kia Sorento (MQ4) can cause electronic interference. Kia names audio static and malfunctions in other electronic systems as the result. We disconnect each add-on in turn to find the source, then remove or replace that device.

A hot plug at the 12 V socket
A plug that does not make good contact in the power outlet of a 2021 Kia Sorento (MQ4) can overheat and open the fuse. We replace a heat-damaged socket and its wiring, then test the plug fit and the fuse.

A floor mat under the pedals
Kia warns that a floor mat not secured to the floor anchors of a 2021 Sorento (MQ4) can interfere with pedal operation. Kia also bars stacking one mat on another, such as a rubber mat on a carpet mat. We fit mats that lock onto the car's anchors and take out the second layer.
