Water leaks in 2008-2010 Malibus
It seems quite a few people have had problems with water leaks in their cars. I am thankful mine is dry, but I sympathize with owners whose cars leak. Many years ago, I had a very nice Mercury Monarch Ghia with a water leak and the dealer could never find out where it came from. I didn't know it leaked until I found out there had been enough water in the carpet to ruin the bag in my vacumn cleaner, it was soaking wet.
Doesn't Chevrolet run the cars through a water chamber to check for leaks? I saw the Camaro manufacturing plant on a TV documentary and they check each car for leaks. However, the car was fully assembled at the time as I believe this was the last QC check.
It would be beneficial to have each car checked for leaks at a certain point in production before the interior is all in place. That way any leaks could be detected and easily fixed. However, I know this would really interrupt the build process.
Just my thinking...
