After a hard rainstorm the Comfort System Control Module (CCM) errored apparently from getting wet from a clogged sun roof drainage line, causing water to enter the rear left side compartment in which the CCM is housed (behind the insulation). The entire area is still damp 3 days later, and water is also located in the tire well and the rear right side compartment. The CCM error in turn caused a cascade of other errors, including causing the rear lights to stop working, an obvious safety hazard. As is evident from online discussion boards this is a frequent issue with this model and a clear design flaw. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The car windows were down the windshield wipers were running the front lights were on and parking brake light is flashing. I'm not sure how water was sitting where the spare tire was located. As I researched it stated it may be a faulty comfort module.
