NHTSA complaint #11670654

Owner complaint summary

Vehicle experienced water intrusion through sunroof drainage system during rainfall, causing saturation of interior components and electrical malfunctions. Water accumulated in cup holders, dashboard areas, and saturated headliner materials. Following water exposure, vehicle developed multiple safety-critical electrical failures including: false forward collision avoidance system activation causing unexpected emergency braking with no obstruction present, and improper auto start/stop system engagement during low-speed driving causing vehicle to jerk and stall while in motion. Despite reporting this safety issue immediately, manufacturer Genesis Motor America failed to disclose that this was a known defect covered under Technical Service Bulletin 24-BD-008G. Customer service representatives did not mention existing TSB and refused emergency service appointments, forcing 2-month wait for service scheduling despite life-threatening electrical malfunctions. Customer had to independently discover TSB documentation through research. Only after customer escalated with TSB evidence did Genesis authorize repair. Dealer confirmed drainage system failure and completed repairs per TSB guidelines that manufacturer should have immediately referenced. Genesis's failure to disclose known safety defect and refusal of emergency service created extended exposure to dangerous electrical malfunctions that could result in accidents.
