found standing water in the trunk area, about 5 inches of it. got it out and took the car in to have them find/fix the water leak. the car has been in the shop 3 times for water leak. each time the mechanics say they found it. they don't. it still leaks. now the roof fabric is stained, the passenger dome light has come undone, and it leaks through the passenger dome light onto my son who is in a car seat. really really crappy design. I have read it is very common for GM/Cadillac vehicles to leak
