No, rainwater should not normally get under the car bonnet in the UAE, but the risk here is different than in rainy climates. The primary concern during our intense, short downpours or when driving through flooded patches on roads like Sheikh Zayed Road is water being forced upwards from the road, not just from above. The bonnet seal is crucial, but dust and sand accumulation from our frequent sandstorms can degrade these rubber seals over time, making them brittle. According to maintenance guidelines from the RTA Dubai, checking the condition of the bonnet and body seals is a recommended part of pre-summer vehicle inspection, especially for vehicles over 3 years old. A 2023 report by the UAE Ministry of Energy and Infrastructure on vehicle efficiency also indirectly highlights that a compromised engine bay seal can affect engine cooling efficiency in extreme summer heat (above 45°C), as it disrupts the designed airflow. For a common GCC-spec vehicle like a Toyota Land Cruiser, the cost of neglecting a damaged seal can add up: a full seal replacement might cost around 400-600 AED at a non-agency workshop, but the potential moisture ingress could lead to corrosion on electrical connectors or alternator issues, contributing to a higher long-term cost of ownership. The bonnet's insulation layer (often a thick foam pad in SUVs like the Patrol or Pajero) is also key; if it gets waterlogged, it loses its heat and noise insulation properties and becomes very heavy.
