2013 MERCEDES-BENZ GL450

I am reaching out to bring to your attention a significant manufacturing flaw in the Mercedes GL450 model, which poses a severe risk to both vehicle functionality and passenger safety. The issue pertains to water infiltration into the battery compartment situated beneath the front passenger seat and concealed beneath the carpet. Even minor rainfall or streetwater has been found to breach this compartment, causing extensive damage to the vehicle's electronic systems. This results in highly precarious and unpredictable behavior, endangering both occupants and road users. As a poignant example, my own GL450, a 2013 model, has exhibited alarming symptoms. Despite being securely in "PARK" mode, upon simply opening the car door, it displays a distressing message: "Transmission Not in P Risk of Vehicle Rolling Away." Furthermore, the transmission intermittently ceases to shift from "P," presenting an imminent hazard to myself and my children. Despite numerous attempts to engage with Mercedes Headquarters regarding this critical matter, regrettably, they have declined to address the issue, citing its expiration beyond the warranty period. However, extensive research indicates that this flaw is pervasive among GL450 owners, as evidenced by discussions on various automotive forums, such as: [XXX] [XXX] I am profoundly concerned about the gravity of this situation and implore you to take immediate action to rectify this widespread issue. Please feel free to contact me at your earliest convenience at [XXX] . I am more than willing to provide further details regarding my experiences and observations. I earnestly anticipate your prompt response and resolution to this matter. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
