I have and am the original owner of a Kia Cadenza 2017 with the 3.3L Lambda engine (same engine as the Sorento lawsuit). The vehicle is currently at the dealership getting repaired due to carbon buildup causing the fuel injectors to malfunction( despite of consistently being on top of maintenance and oil changes).I have read online of lots of users with failed engines due to carbon buildup in these engines. The warning lights I got were p0171,p0174, and p0191, and am worried that after the repair the engine will eventually fail due to the buildup as the main issue isn’t properly being addressed. The issue occurred about 300 miles ago where the dealership erased it. Then told the vehicle did not have any issues. Brought it back to the Kia dealership where they finally gave a proper diagnosis after being told nothing was wrong with car. I am concerned as there are lots of owners online experiencing the same issues with their Kia cadenzas and nothing done about it. Took the vehicle in a

This vehicle was inherited to me in 2019 from my father who puchased it cash on 10/13/2017. On 4/19/2018 he brought it in for a check engine light which was related to recall sa299 (ELECTRONIC THERMOSTAT). On 7/11/2018 service was performed again. On 3/4/2022 I brought in for check engine light with same recall for ELECTRONIC THERMOSTAT. On 11/10/2025 car showed engine overheating. In fear, I immediately brought to closest mechanic stating same problem, ELECTRONIC THERMOSTAT AND RADIATOR HOSE WHICH GOES HAND IN HAND. Before work began I left voice mails and emails with the service manager of Rohrman Kia in Schaumburg, Il. No one reached out. I spoke with Jim at same location on 11/10/2025 at 4:00 pm who told me it was my responsibility because the part was no longer under warranty. I filed a complaint (24149522) with BBB. on 11/13/2025 after I had to pay my mechanic $1000 to fix problem which obviously is a defect. On 12/3/2025 I spoke with Mike from Kia who said part was no

I am submitting a complaint regarding my 2017 Kia Cadenza related to an ongoing airbag system failure and Kia’s refusal to cover the repair under their existing airbag warranty extension. My VIN is included in Kia’s WTY027 warranty extension, which extends coverage for repairs related to the Airbag Warning Light illumination from 5 years/60,000 miles to 15 years/unlimited miles. Despite this, Kia Affairs has denied coverage because the diagnostic trouble codes (DTCs) pulled by the dealership do not “exactly match” the codes listed in the extension, even though the warning light is on and the issue affects the Supplemental Restraint System (SRS). Kia Affairs acknowledged the problem and escalated the case to their District Parts & Service Manager (DPSM) for possible goodwill coverage. However, goodwill is discretionary and not guaranteed, leaving me potentially responsible for expensive labor costs on a federally required safety system. My Concerns: The airbag light remains

While driving 80 mph on Interstate 25 in Wyoming, my wife, great granddaughter (in a car seat), and I (driver) suddenly heard a LOUD bang, followed by wind noise coming from the top of the car. I opened the moonroof and found that the sunroof had exploded and shattered. We were on the northbound lanes with no traffic, other than 1 pickup truck in front of us by approximately 200 yards.There was no evidence of debris hitting it. Temperature was in the low 80’s at approximately 5:30 pm. I have no explanation for the sunroof exploding. Being that the incident happened on Friday evening, I have yet to take the vehicle into a dealer or glass shop

A little history, my Cadenza was placed at KIA of Bradley [XXX] 2024, I complained of oil burning, the oil sending unit light staying on and the engine dying. The Kia rep found “THE OIL PRESSURE SENDER INTERNALLY FAULTED, LEAKING OIL INTERNALLY – OIL LEAKING DOWN TO PIGTAIL HARNESS”. The Oil pressure switch and wiring harness lead were replaced. Here lies the problem. During my visit in Feb, I told Kia about the burning oil smell, I provided a video of the smoke coming from the engine and the oil light staying on. I was relying on Kia’s expertise because it’s their product. The complaints I had were about the same issues the KIA Sorento 3.3 L had, considering my Cadenaza has a 3.3 GDI engine also. The Sorento’s engine was recalled. Move forward to [XXX], 2024, I brought my Cadenaza to Kia of Bradley to have my windshield fluid motor checked because only the passenger’s side was spraying fluid, after Kia telling me the car would probably be held for a couple of days I de

I purchased my 2017 Cadenza, Sept 2022. I've always had problems with the engine. Coolant loss, smoke from the engine after drving , loss of power and oil loss. This past August 2023 I had to replace my AC valve for 3800. My engine has gotten worse. smoke constantly comes from the engine and now my oil sensor light is coming on. I've always done maintenance on the car. Oil changes and the required milage maintenance. I've notice other owners of the 2017 cadenza have had the same problems. I'm the next step will be my engine sizing. I notice several 3.3 engines and 2017 models have been included in the recall. My 3.3 engine is doing the exact things of the other recall cars. I hope my car is included in the recall thank you.

McGrath Arlington Kia in Palatine, Illinois stated I had a recall I live over 55 miles from this location. Base on the distance my contract states I can pick a closer location. When I contacted Bill Walsh Kia in Ottawa, Illinois. Service department stated they can not find the recall in there system, so they can't fix the recall. Their explanation was that my car had done made in Korea a Kia motor corporation. So I'd have to take it to Korea to get it fixed. Please advise on fixing recalls for this car. I didn't know this would be an issue when I purchased it. Cell [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
