My 2018 Cadillac XT5 has a serious water intrusion issue—water is leaking into the interior cabin through the sunroof or roof seams. This appears to be the result of a known manufacturer defect covered in GM’s Technical Service Bulletin TSB 19-NA-167. The leak has caused significant water accumulation on the floor, raising concerns about mold, electrical failure, and corrosion. I brought the vehicle to a Cadillac dealership, and they confirmed the issue. The total repair estimate is around $7,900. Cadillac offered partial goodwill coverage, but I am still being required to pay $3,400 plus tax out of pocket. I have authorized the repairs but am seeking reimbursement for the portion Cadillac is not covering, as this is not normal wear and tear—it is a clear defect in manufacturing that poses safety and health risks. GM should be fully covering this issue for affected vehicles.
