During a highway trip that was bumper to bumper traffic at approximately 15mph, the car suddenly would not accelerate while operating on gasoline (not electric).

Owner report 11740246 · 2026-05-26 (May 26, 2026)
Installing a car seat and the belt buckle failed. The plastic part split and no longer holds the belt together. This was under regular pressure with standard leverage that the car seat design calls for. Nothing was ever on top of the buckle and it is not damaged in any other way at all other than the failure. They refused to replace it via warranty.
