Chevrolet Malibu trunk leak causing mold and moisture issues after heavy rain on Chevrolet Malibu

Some Chevrolet Malibu owners report experiencing trunk leaks that lead to mold and moisture issues after heavy rain. Common sources of these leaks include the center high mount stop lamp, which can cause water to accumulate in the headliner and trunk. Additionally, some owners have identified the trunk gasket or the area around the third brake light as potential leak points. Water pooling in the spare wheel well may indicate leaks from the rear compartment lid weatherstrip or misapplied trunk body sealant. Other possible sources of water ingress include problems with the door membrane, cabin filter, sunroof, door seals, air conditioning, windshield weather stripping, improperly installed lights, and aftermarket accessories. To mitigate mold and moisture problems, it is recommended that owners inspect these areas regularly and take appropriate measures to seal any identified leaks.
