How serious is the body problem on the 2024 Kia Carnival?
It's a documented issue but not catastrophic. 5 complaints have been filed. Repairs average $1,500 and most owners catch it before it causes a breakdown.
At what mileage does the body typically fail?
Based on the 5 complaints filed, body issues most often appear around 25,000 miles. Some report problems earlier; some make it well past 150,000 with no symptoms. Maintenance habits matter — vehicles that received timely fluid services and were not regularly overworked tend to last longer.
What does it cost to fix?
Independent shops typically charge around $1,500 for body repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
