What are the reasons for water ingress under car floor mats during rainy days?

[MacLincoln]

Car floor mats may get wet during rainy days due to reasons such as sunroof leakage, air conditioning leakage, or the vehicle driving through deep water. Below is a detailed introduction about car sunroofs: 1. Overview: Car sunroofs are installed on the roof and effectively promote air circulation inside the vehicle, increasing the intake of fresh air and filtering the interior air, thereby protecting the health of drivers and passengers. Additionally, car sunroofs can broaden the field of vision and meet the needs of mobile photography and videography. 2. Classification: Car sunroofs can be broadly categorized into: sliding-out, built-in, built-in flip-out, panoramic, and curtain types. They are mainly installed on commercial SUVs, sedans, and other vehicle models.
