针对有媒体在赛道测试小米YU7时刹车片起火，小米汽车于6月28日晚在最新一期答网友问中回应称，视频中，小米YU7 Max在天津V1赛车场进行1个暖胎圈+1个飞行圈后，在未进行散热圈的极端情况下，直接驻车，高温导致制动片有机物材料发生起火，但制动系统整体未出现任何制动失效等问题，功能健全，使用正常。此外，测试车辆未使用小米YU7 Max大师模式中的“能量回收增强”功能。 据小米汽车介绍，小米YU7 Max采用低金属制动片，材料包含金属纤维、磨料、树脂等有机物。树脂及其他有机物在高温下(一般大于300°C)产生聚合物支链裂解反应产生部分气体，如水分、一氧化碳、二氧化碳、烷基、芳香族气体等，其中部分可燃气体在高温（一般制动盘温度＞600ºC）及氧气充足的环境下可能会产生短暂明火现象。这属于一种正常的物理现象，但制动性能不会失效。
