Rodents chewed through the main wire harness on my vehicle on 2 separate occasions, both times in the same exact location. This recurring damage poses a serious safety risk and may be linked to soy-based wire coatings that attract rodents. The first incident required a $4,979.27 repair, covered by insurance; I paid a $500 deductible. The vehicle was diagnosed by Boonton Auto Body Shop. I recently discovered a second instance of rodent damage in the exact same location, which has not yet been repaired. This led me to investigate further and learn that this may be a common issue in certain vehicles, possibly due to soy-based insulation. I filed a complaint with Kia, but they denied responsibility. The main wire harness is critical to safety systems including braking, steering, engine performance, lighting, and airbags. Although I caught the issue before any accident occurred, undetected damage could lead to serious safety failures while driving. Some may argue the issue is environmental, but I also own a 2012 Toyota Prius, which I own and park in the same location since 2012. That vehicle has never had any rodent damage. This suggests that the problem is not just environmental, but may be due to the design, material based, or placement of the wiring in the Kia. Many consumers are unaware they can report safety-related issues to NHTSA. After being denied by the manufacturer, most are left with high repair costs and no resolution. I am concerned that if consumers remain silent or unaware of this process, Kia will not be held accountable. This is not an isolated case. The repeated, location-specific failure and the manufacturer’s refusal to act show a clear pattern of potential design defect. I urge NHTSA to investigate this issue seriously, issue a recall to ensure Kia addresses the problem and protects consumer safety, and require the manufacturer to reimburse affected consumers for repair costs. This issue must be addressed before a serious accident occurs.
