Why does the hood of the Tiguan pop open automatically?

[AndresFitz]

Volkswagen Tiguan engine overheating, the reasons why the hood automatically pops open are as follows: 1. Insufficient coolant: Prolonged water circulation during engine operation can cause the coolant in the engine cooling system to gradually deplete, leading to insufficient water in the radiator. If the owner fails to promptly inspect, detect, and replenish the coolant, it can easily result in engine overheating, causing the hood to automatically pop open. 2. Cooling fan malfunction: Damage to the cooling fan or short circuits in the wiring can cause the fan to stop working or operate at a slow speed. This prevents the engine's heat from dissipating, naturally causing the engine temperature to rise and the hood to automatically pop open.
