2023 Kia Sorento Complaints

Faulty fuel injectors are causing consistent engine misfires and occasionally causing the check engine light to illuminate and for the vehicle to reduce power greatly. This poses a great safety risk to both myself and other drivers on the road because in the event of a large misfire, my vehicle suddenly slows and I have to navigate to the shoulder of the road. A Kia dealership has confirmed that the cause of these misfires is due to a faulty fuel injector that begins to work inconsistently above 3000 RPM. This issue began shortly after the vehicle was purchased in 2023, but due to the dealerships inability to replicate the issue it went without correction. In the recent year, this issue has increased greatly and it is now a consistent issue and this is why it was able to be diagnosed now. This is a very common and widespread issue amongst other individual with vehicles with the same engine.

I am submitting a vehicle safety and certification concern regarding a 2023 Kia Sorento Hybrid that was marketed and offered for sale as a Kia Certified Pre-Owned (CPO) vehicle by Shawnee Mission Kia, 7951 Shawnee Mission Pkwy, Mission, KS 66202. On [XXX], during an in-person inspection of the vehicle prior to purchase, I observed conditions inconsistent with expected Certified Pre-Owned inspection and preparation standards, including inverter coolant below the minimum level, engine oil materially above the normal operating range, and deteriorated windshield wiper condition. A third-party witness was present during the inspection. Because the vehicle was being represented as Certified Pre-Owned, I requested the vehicle’s CPO inspection checklist and supporting inspection documentation from dealership personnel. The requested documentation was not provided despite multiple follow-up requests. Subsequent written communications from dealership management acknowledged failures in dealer...

All lights came on the dashboard including the check engine light and I could not accelerate. I had to pull over and turn car off and on to get it to accelerate. It poses a very serious threat as you can not accelerate at all and can be rearended. Kia has fixed the throttle twice and have told me 2 other times they can not replicate the issue. It clears out by the time I am able to bring it to the dealership. This issues has happened 4 times starting at 9,000 miles and most recently at 21,000 miles.

I have had to replace my radiator twice in under 2 years because the open spaces in the grill are too large and rocks are able to go through them and puncture the radiator.

Immediately after a dealership-performed warranty repair, the vehicle experienced a severe safety‑critical failure at highway speed. The vehicle began shaking violently, produced loud knocking and impact noises, and metal pieces fell from the underside. The failure occurred without warning and created an immediate loss of safe drivability. The dealership later documented that an engine mount (‘lower dog bone mount’) had not been torqued to specification, which allowed the engine to shift back and forth under load. This improper torque caused the violent shaking, metal impacts, and falling metal. The problem was confirmed by the dealership, but no corrective repair was performed. Only a single bolt was re‑torqued, and no inspection was done to determine the extent of damage, the source of the falling metal, or the cause of the knocking. The vehicle was returned in an unsafe condition and has not been driven since. The vehicle had to be towed directly from the highway due to the sever...
