New Car Assessment Program

The 2018KIASORENTO carries 305 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 12 crashes, 18 fires, 9 injuries, and 0 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall 5/5 rating, with 5/5 front crash, 5/5 side crash, and 4/5 rollover scores derived from standardized barrier and dynamic tests.

Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2018 SORENTO is engine with 93 filings, followed by exterior lighting (36) and unknown or other (35). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 3 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.

NHTSA currently has 8 investigation files overlapping the 2018 SORENTO. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

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.

20260204FUEL/PROPULSION SYSTEM

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

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.

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 deal

My Vehicle’s Problems Excessive Oil Consumption My engine kept losing oil far more rapidly than normal. I was regularly checking and had to top off the oil, even though mileage suggested it should not be that frequent. However, there was no “check engine” warning light or low-oil warning light even when the oil level was dangerously low. Despite the oil being burned or lost, none of the sensors ever alerted me. Eventually, before my next scheduled service, the extreme oil loss culminated in catastrophic failure: the engine seized, and the car is now completely undrivable. Engine Failure / Seizure The engine’s seizure was sudden and without any prior warning. There was no indication via “check engine” light, oil light, or other dashboard warnings. I have obtained an estimate for replacing the engine, and regrettably, the cost of a new engine exceeds the current value of the vehicle. This is deeply unfair, given that the root cause appears to be excessive oil consumption
