Consumer Description

Gateway unit that is located under the rear seat has an inadequate insulation and is susceptible to liquid exposure and electrical failure. A liquid penetrated the rear seat and short-circuit the gateway while vehicle was moving resulting in a near-accident by shutting down power steering, brakes, and many of the car's systems. Failure messages began appearing and vehicle was unresponsive to driver actions. Emergency blinkers were not working at the tail lights which is a critical safety hazard for a disabled vehicle on the road. Dealer confirmed gateway unit failure due to the water exposure and recommended the replacement of the unit. Vehicle had no warning lights or messages prior to the incident.
