Hello, My father's Cultus 2017 (Islamabad) has this issue. It was parked in rain for 2-4 hours in the morning, when we checked the spare wheel trunk it was filled with some water. Although all the rubber seals of back door are dry and the mat cover placed on the wheel was also dry except near the trunk door lock.
There are also no drain holes in the trunk (there were two round holes but the are covered with metal and sealant ).
Is this issue also present on the other cars as well?. We haven't yet checked it with the Suzuki dealer. Is it a company manufacture issue?
Has any one experienced the same?
