NHTSA Complaint #11465359 — 2015 VOLKSWAGEN GTI

The coolant shutoff valve/water pump has failed twice in a little over 13,000 miles. The first incident caused the engine to overheat and go into "lump mode" on the highway and would not go over 45 mph. In the 2nd incident, the coolant shutoff value because stuck in an open position, resulting in poor gas mileage and an engine that takes much longer than normal to reach operating temperature. Problem has been confirmed by the dealer that performed all scheduled maintenance. The component has not been inspected by the manufacturer, police, insurance or others. Warning Lamps: I was not the driver during the first incident. The 2nd incident, the engine warning light came on within a couple of days of a major maintenance at the dealership.
