Owner reports
Selected complaints filed with NHTSA by 2018 Kia Sorento owners, lightly cleaned up (personal details are redacted by NHTSA).
The vehicle's ignition system began malfunctioning immediately after a recall-related service (Campaign CS2312 - ignition cylinder protector installation) performed on January 9, 2026. Prior to this service, the vehicle had no ignition or electrical issues. After the repair, the ignition key became difficult to turn, and the vehicle intermittently failed to start. Additionally, multiple electrical components began to fail intermittently, including the infotainment screen shutting off, the air conditioning system stopping, and windshield wipers not operating at times. These failures create a safety concern, as they may affect visibility, driver awareness, and vehicle operability while driving. The issue was reported to the dealership, and their own inspection confirmed that the ignition key cylinder is sticking. The vehicle remains available for inspection, and the condition persists.
Having intermittent issues with the headlights turning of while driving at night. The headlights were set on "Auto". I have had this happen multiple times! Went to local dealer to report the problem & was told that they would have to drive it at night to replicate the issue. I asked if I would be charged for this & was told that if the technician could find anything that I would be charged for the technician's time. I found online that Kia had this same issue with 2015-2015 K900 vehicles & issued a recall to replace the multi-functional light switch. Losing headlight rumination can reduce visibility and increase the risk of a crash. Kia dealerships should replace this multi-function switch free of charge to the owners of Kia vehicles. There should be a recall issued for this issue because it is a huge safety issue.
The contact owns a 2018 Kia Sorento. The contact stated that while driving at an undisclosed speed, the headlights failed to function as intended. The contact, who was a retired certified mechanic, inspected the headlights and determined that the passenger's side headlight bulbs were blown. The contact then noticed a burning odor in the circuit board inside the headlight. The contact stated that the front passenger's side headlight bulbs were replaced twice within three months due to failure. In addition, the contact stated that an unknown manufacturer's recall was performed approximately two years prior, and the multi-function switch knob was replaced. The contact stated that the headlights were not replaced at the time. The manufacturer was not made aware of the failure. The failure mileage was unknown.
The headlights will occasionally turn off at night while driving. We have to then turn them back on by touching the light switch. The are set on AUTO always and should not go out AT NIGHT, especially while driving. They should only go out when exiting the car after engine shut off. The parking lights (front and back) occasionally do not turn off when leaving the car, after engine shut off. They are also on auto and should go off so the battery does not drain. A few times they have even come on when we were not in the care and we discovered them on after a period of time when returning to the car. The dealer could NOT find a problem and did nothing to resolve it.
While driving at night, the headlights turn off by themselves randomly. The lights need to be turned to off and back on to get them to turn back on. Driving with no lights in an area with no streetlamps obviously could result in an accident. It has not yet been inspected by anyone yet, but a check is scheduled. There were no warning lamps, messages, etc. when the lights turned off. Not a safety concern, but seems related: On another occasion, the car had been parked and locked for hours with the engine off, and the parking lights turned on and remained on until manually shut to off. They did not turn off by a remote unlock and lock.
Lighting and/ or electrical. When using the auto headlight switch, all lights will come on randomly and periodically and stay on until you notice them or they ware down your battery. This is something that could be checked out by dealer and I will ask about it. So, for now, I do not use the auto headlight switch. My other problem is a glass issue. For no apparent reason, when I shut my driver side door a few weeks ago. My entire rear window shattered into pieces. There were no signs of damage to the rear window. Happened in my drive way. But, it could have happened anywhere. Filed a insurance claim and had the rear window replaced.
In April, 2025, my vehicle's engine power was significantly reduced while on the highway. I could not keep pace with traffic. My mechanic said there were recalls for the turbo engine but my car was not included. I paid forbthe part and repair. Less than a year later and the car began burning a lot of oil very fast. I add oil weekly. The car has again been losing power and there is still no recall for my car's engine. There is burning and smoke coming from the engine because of an engine oil leak Jiffy Lube detected yesterday, Mar h 11, 2026. The problem began at around 65k miles and now has 88k miles.
While driving at night with headlights set to "auto" the car will (without moving the physical switch) change the headlights to "off" for approximately 2 seconds, after which it will change them back to "auto". This causes a momentary loss of vision to the driver. The drivers display shows the change from "auto" to "off" as though the switch had been turned. I am unaware if this also happens in lighted conditions, as It is only noticable when you are driving in the dark. It appears as though this has happened to multiple drivers of different vehicles
My lights keep going out as I`m driving at night time so i can not go any where at night time I was almost hit head on this the second time this happened when I called Kia 3 times now the dealer i purchased it at they keep giving me a run around I have the extended warranty also electrical warranty which i paid extra for they still want to tell me these things aren`t covered.My vehicale has not had any of the software updates. I have tried calling a Kia dealer closer to my home I get told i have to go were i purchased my Kia
Driving down a dark highway tonight and headlights just randomly went out completely. Had to switch them on and off several times to get them back on. Safety risk is obvious for myself and other cars on the road. Has not been inspected, just happened tonight. I have noticed my lights cutting on and off during the day randomly lately but I just assumed it was the auto mode picking up shady areas but it appears to all be related based on the thread I just read online and sounds like an issue with this year Sorento.
