What 248 owners told NHTSA about the 2018 Kia Sorento Plug-in Hybrid

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.

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.

My speedometer was jumping from 0 to 20 mph while in park. A couple weeks later it did it while I was driving, I was going 25 mph and it jumped to 55 mph. I took it to the shop that day and all 4 of my wheel speed sensors were out, which wasn’t accurately measuring my speed. The shop said it was common with this model and year. Also, my headlights do not work in auto mode. I will have shut my car off, made sure the lights were off, and hours later I have a text from my neighbors that my lights are on.

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 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.

My lights are set to auto but when driving they randomly switch off. The dash shows the switch from auto to off but the control is still set to auto. I have to manually switch the control off and then back on for the lights to come back on. I’ve also noticed a few times in the morning my lights are on. My switch is set to auto and my car is completely off but the lights are on. This is very unsafe as it happens at night and I can’t see the road.

The passenger side headlight has been reinstalled 8 times. The dealership has replaced it and we have replaced it several times. The light goes out constantly and is costing me a fortune to replace as well as possible traffic tickets. The headlights turn off also when in automatic mode. Please recall this vehicle and have this safety and expensive issue fixed. This issue has been going on several months now. The dealership does not provide a permanent solution. This is a defect.

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.

This just happens with no warning. Please Fix.

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

10/5/2022 Driving down Texas Interstate 20 last night, just east of Willow Park, Texas the headlights turned off. I switched the lights from the auto position to the On and the lights turned back on. Wife informed me this has happened to her previously as well. Driving down the road at 70 MPH and everything goes dark is a bit frighting. From my search, this has become a common issue with our KIA model. The issue happens randomly so difficult to pinpoint the issue.
