NHTSA summary
The Office of Defects Investigation (ODI) opened this Preliminary Evaluation (PE) based on seventy-four Vehicle Owner Questionnaires (VOQs) reporting headlight failures on model year (MY) 2011-2013 KIA Sorento vehicles.In its response to ODI's June 25, 2020, information request letter (portions of which were submitted under request for confidentiality), Kia Motor America (Kia) provided design details of the headlight system showing that each headlight circuit is independently powered by the Smart Junction Box (SJB), a power control module. Kia claimed that the design minimizes the chance of both headlights failing simultaneously due to a headlight connector defect, a component located downstream of the SJB. Kia also advised that the SJB contains a safety feature designed to monitor power consumption for each headlight circuit; if excessive current is being demanded by either headlight the SJB will open the circuit (i.e., stop supplying current). Lastly Kia presented testing showing that the maximum headlight connector temperature achieved prior to the SJB opening the circuit was below the autoignition temperature of the plastic material the connector housing is made of, which Kia maintains eliminates the potential for a fire originating from an electrically overheated headlight connector. In its review of all available data, ODI determined that the majority of both VOQ and Kia customer complaints (1,339 reports in total) involved the loss or dimming of a single low beam headl

None of these investigations covers the 2017 model year.

What owners wrote

“Headlights go off without warning while in auto driving at night . Has occurred 2 in the month of August 2022. Can be turned back on by twisting the control nob to on. Poses a dangerous situation on the dark county roads that we drive if not quick enough to manually turn back on.”

“The "auto" headlight function keeps malfunctioning. It will randomly shut off the headlights and not turn back on. Numerous forums have reported the issue. This is extremely dangerous when driving at night.”

“When driving down the the interstate at night, my headlights just turn off while driving. They are on Auto. This has happened multiple times while driving. I have not took it to be looked at yet. There is no warning light or anything else that lets you know that there is a malfunction. The lights just go off. For them to come back on, I have to manually turn it off and back on again, and they will come back on.”

“When “auto” for headlights the lights won’t turn on at night time unless I manually switch it or the lifts will be on and then go off on their own during the night.”

Should you keep driving it?

This page can't tell you that. 1 of 101 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
