My toddler, 3 years old climbed into my 2022 Kia carnival to get into his car seat. I was standing outside the door waiting to buckle him when the sliding door started to close on its own and my toddlers leg got trapped under the track of the door and he started screaming. I then had to put my whole body between the door with force to prevent it from closing all the way. I was then able to pull his leg out. There has been no inspection to the vehicle yet as it happened last night. There were no warning or messages about the problem prior and we have had no issues like this before.
