Our 2024 Carnival has had a recurring engine oil leak that has required the vehicle to be left at the dealership 4 times for the same issue. Each time we get the van back the repair lasts about 1-3 weeks (depending on how often it's driven). Oil continues to leak from the engine area, creating risk of engine damage or a potential fire hazard if oil contacts hot components. The issue has not been resolved despite repeated repair attempts under warranty. The Carnival has 38,092 miles on it, and has been in the repair shop over 4 times. The 1st time it was put in the shop the van has 34,420 miles on it. Each time it has been left at the dealership for 9 - 17 days while the repairs were made. We have brought it to the same dealership each time and they have been very sympathetic and helpful. Not only does this issue cause the risks mentioned above, but it has ruined the concrete in my garage as well as added oil to the roadway which could cause an accident. I have all the repair orders from the first 3 repairs that I will attach. However I do not have thee current one because the vehicle is currently being repaired for the 4th time and I haven't received the finalized repair order documents. I can update this claim once the repairs are completed. I will be contacting Kia tomorrow and wanted to have a claim number started.

The contact owns a 2023 Kia Telluride. The contact stated that while driving at an undisclosed speed, the transmission was slipping. There was no warning light illuminated. The contact stated that while the vehicle was stopped, it unexpectedly lunged forward. There was no warning light illuminated. Additionally, there was an abnormal sound coming from the muffler. The vehicle was taken to the dealer, where it was diagnosed and it was determined that the ECM software had failed and needed to be reprogrammed. The vehicle was repaired; however, the failure recurred. The vehicle was taken back to the dealer, but was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 91,000.

Within just two years of normal use, the front driver-side leather seat in my vehicle has developed multiple cracks. I contacted the dealer and was dismissively told this obvious defect is considered “normal wear and tear” and therefore not covered under warranty. I then contacted Kia customer service, only to be told they “do not handle warranty issues” and that everything is the dealer’s responsibility. This complete lack of accountability is unacceptable. If Kia’s so-called “leather” seats cannot last more than two years, then the product is clearly substandard. Had I known the materials were this poor and customer support would be this unhelpful, I would never have purchased a Kia—let alone paid extra for a leather interior. Between the low-quality materials and the ineffective customer service, this has been an extremely disappointing ownership experience.

Standard opening of sunroof, the a part of the wind deflector snapped, without any abnormal incident or misuse. This caused the glass to be misaligned and other damage to the sunroof track. Estimated cost $6000. No warning and no prior damage for causation.

The contact owns a 2015 Kia Sorento. The contact stated that while driving at undisclosed speeds, the vehicle hesitated to maintain automotive power. No warning lights were illuminated. The vehicle was taken to a local dealer, where it was diagnosed; however, the diagnostic result was not available. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 94,000.

I purchased this 2024 Kia Carnival on 2/7/2026 with less than 10K miles. The vehicle has died while I was driving 4 different times. Twice each day that it happened. The first time was on 4/7/26. My car died on the way home from getting my kids from school after fixing a flat tire. The check engine light came on after getting a jump and when I took it to Auto Zone the battery was fully charged and the codes were for the Power Train, which didn't make sense for a brand new car. Miracle Mart told me that Kia needed to be utilized for any issues because I purchased the vehicle as is. Their solution was to tighten the "loose cables". On 4/25/26 the car died again two more times. Something is terribly wrong with this car.

Intermittent failure of multiple safety-critical Advanced Driver Assistance Systems (ADAS) while driving. Forward collision avoidance, lane safety, and other driver-assist features disable simultaneously without warning.

ICCU failed despite all prior recall updates being performed. Incident began when home circuit breaker tripped; vehicle subsequently refused Level 1 charging with "Check Electrical System" warning. Per dealer suggestion, tested public chargers. Level 3 (DC) worked, but upon connecting to Level 2 (AC/J1772), a loud "pop" occurred, and the public charging station immediately suffered a mechanical failure/shutdown. Vehicle then displayed "Stop vehicle and check power supply," and was unable to drive above 40mph (with a turtle icon visible on the dash) once I pulled away from the charging station. This created a significant safety hazard while navigating traffic. Within two hours, the 12V battery was completely depleted; vehicle was unresponsive and required a jump-start for towing. Dealer confirmed ICCU failure requiring replacement. The fact that the vehicle's internal failure caused the immediate malfunction of public infrastructure is deeply concerning, as was the loss of motive power on the road.
