2018 KIA SORENTO Complaints

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.

2018 Kia Sorento 2.4 GDI. In late 2024 a Kia dealer performed an oil-consumption test and confirmed the engine was burning excessive oil. In Feb 2025 the engine long block was replaced. Within about 4,000 miles the vehicle began setting P1326 warnings, misfiring, losing power, and struggling to climb hills. On a highway trip from South Carolina back to Indiana, the vehicle could barely maintain 30–40 mph on grades with the accelerator floored while traffic was moving much faster. The check-engine light returned repeatedly. The vehicle eventually died on an exit ramp and had to be pushed out of traffic and towed. I felt it was unsafe to drive but was repeatedly told by dealers that it was “OK to drive” or that the issue was “bad gas.” After visits to multiple dealers, the current Kia service center finally diagnosed a severely clogged exhaust. They report the manifold catalytic converter and underbody converter have broken down internally and are heavily coated in carbon/oil deposits, and state this likely came from the engine burning oil before and around the time of the rebuild. Exhaust temperatures have been recorded at very high levels, and the engine will only run briefly with an O2 sensor removed to vent exhaust; with the exhaust sealed it will not stay running. The dealer has warned there may now be internal engine damage from prolonged backpressure. The vehicle has been undriveable for many months and the failed converters are being retained and are available for inspection. My concern is that excessive oil consumption on these GDI engines is causing secondary catalytic-converter failure, extreme power loss, stalling risk, and possible fire risk from overheated exhaust components, even after engine replacement.

My car had an issue that was covered under a class action lawsuit. I even had an extended Warranty which was still valid at the time. I was intimidated by the warranty company when they said well if there is carbon build up in the engine the cost of the repair is on you. So I didn't have it fixed and the engine blew up and is now inoperable in my driveway. So bottom line I couldn't get KIA to help me or the extended warranty company when clearly it was KIA's responsibility to fix there defect in the engine.

I was driving and when I lost all power steering the lights on the dash came on for power steering and traction I could not steer at all it was so hard to drive . I reported it right away and had my car check out there is a recall on the power steering but they are saying my car was made in April and the recall starts for cars made in June . Well now they are saying I need a new steering column when u turn the wheel u hear a load clunk noise my dash light go on and off when you turn the wheel and you lose power to the vehicle I also burn threw light bulbs monthly I think it’s also a electrical issue within this vehicle I have already had to get a new engine this vehicle in junk and has costed me a fortune and the keep denying to cover there at fault for any of it and it’s there fault it’s not just my car they are all like this.

Noticed excessive oil consumption that turned into burning oil when the exhaust turned back of car black. Engine started knocking due to gummed up spark plugs. Replaced the spark plugs but within weeks the new plugs where gummed up as well. Took to Kia for diagnosis and potential repair for theta 2 class action. Mechanic confirmed damaged spark plugs, piston issues and needs for new engine.

1. at night when i toggle hi beams the light black out and i have to jiggle the toggle 2. My HECU assembly is out, I have about 7 lights on my dash.

The contact owns a 2018 Kia Sorento. The contact stated that upon starting the vehicle, there was heavy white smoke coming from the exhaust pipes. There was no warning light illuminated. Upon taking the vehicle to an independent mechanic for an oil change, the contact was informed that there was an oil leak coming from the engine. The contact had her son inspect the vehicle, and he discovered that oil was leaking onto the spark plugs in cylinder #1. The contact’s son diagnosed the vehicle with engine failure and recommended that the engine be replaced. The contact then stated that while driving 60 MPH, the vehicle started shaking with the check engine warning light illuminated. The contact pulled over and waited for approximately an hour before being able to restart the vehicle and drive to the destination. The vehicle was then taken to a dealer, where a diagnostic test was performed, and the dealer discovered several oil leaks in various cylinders. The vehicle remained with the dealer. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was unknown.

The engine suddenly failed while I was driving on the highway. The vehicle lost power without warning, which created a dangerous situation. I had to pull over and have the vehicle towed.

Engine is burning oil at a rate of almost one quart per week. The engine can be felt shaking when driving. The engine light came on and states there is a P0303 Cylinder 3 misfired detected.

Started the car and heard a knocking sound. No check engine or low oil light on the dash. Dealership said the bearing clearance test was too great, causing the connecting rod to knock inside the engine. Dealership said I need an engine replacement. Engine is 3.3L Lambda II engine which has been reported to have this issue.
