I am having the same issue. 2017 Disco sport with 24k miles. Last month when starting my car there was an explosion under the hood and green liquid dripping from the front of the engine...towed to dealer...was told by LR it was a coolant leak and the hose was replaced, leak resolved. Yesterday the low coolant light came back on. Taking it back to the dealer. Any theories on what exactly is the issue with this model? Someone mentioned a water pump leaking, is this the culprit????....I will say the recommendation by LR to top off coolant is not acceptable.
