INFINITI G37 sunroof leaking onto front and back passenger floor on INFINITI G37

Problem overview

Some INFINITI G37 owners report experiencing sunroof leaks that cause water to seep onto the front and back passenger floors. Common causes of these leaks include a grommet near the firewall that may lead to drains leaking into the floorboards and clogged drain tubes that allow water to back up and run down the A pillar into the glove box area. To address these issues, owners often find it necessary to clear the sunroof drain to ensure proper drainage and prevent further leaks. Additionally, some owners discover that a leaking heater core could be contributing to moisture on the passenger floor mat, identifiable by a sweet smell and stickiness. Repair options may involve fixing the sunroof drain leak or clog to eliminate water on the carpet and mildew smells, as well as addressing bad seals where the rear quarter panel welds to the main body, which can cause water pooling in the rear passenger area. Promptly identifying and resolving these issues is crucial to maintaining a dry and comfortable interior in the INFINITI G37.
