To whom it may concern, I own a 2021 chevrolet blazer I have been noticing a very large amount of water on the front floor boards since this discovery the windows being moist in the mornings make sence l. The windshield has been replaced several times with no obvious leaks at this location. There is no visible leaks during heavy rain or car washing, the biggest concern i have it if there's moisture I am more likely to develop electrical problems not to mention the moldy smell in the vehicle. I have done extensive research and found this to be a problem with most Chevrolet Blazer's my question is does Chevrolet have a solution to the problem that has found its way to many customers. I would believe with the number of complaints the Chevrolet engineers are working on a solution or a reason for this problem. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
