NHTSA complaint: 2024 HYUNDAI SANTA FE — ELECTRICAL SYSTEM
The vehicle experienced a significant failure of the Body Control Module (BCM). This resulted in multiple electrical malfunctions, including don't detected the Key, Despite the low mileage (12,000 miles), the electronic systems have proven unreliable, and the vehicle is currently undergoing warranty repairs at the dealership. "The sudden failure of electrical components could lead to a crash or leave the driver stranded in an unsafe location. I am concerned about the long-term reliability and safety of this vehicleâs electronic architecture." After arriving home and shifting the vehicle into 'Park', the car began to roll backward on its own. The vehicle continued to move until it struck my garage door. This incident occurred unexpectedly after the transmission was supposedly secured in Park. It was necessary to apply the brakes to make it stop. Although the physical damage was minor (scratches), this unintended movement represents a severe safety risk that could have resulted in a serious accident or injury." I've also noticed that it makes strange shifts in the transmission when going down a steep hill.
