Your third-row seat belts are unbuckling on their own while you're driving, even though your car seats are installed correctly according to their manuals. Since your toddlers can't unbuckle themselves, this appears to be a vehicle defect rather than user error. The dealership has been unable to find or fix the problem, and your dashboard doesn't alert you when the belts come loose. This may require inspection and replacement of the seat belt buckle mechanisms or anchor points.
