The 2019 Volvo VNRE has 2 recalls, both pointing to the same fire risk: a cabin heater relay that can fail and allow the heater system to run continuously, overheating components and raising the risk of a fire.
Loose power cable connections at the windscreen heater relay can cause the relay to stick in the closed position, which keeps the cabin and coolant heaters energized beyond their intended limits. The resulting heat buildup in the relay and heater components can lead to a fire.
