This is a complex issue and CarsGuide does not give legal advice on matter such as this. However, from a practical standpoint, water on the road in puddles could conceivably enter the engine and cause damage if you managed to hit just the right puddle at just the right speed and at just the right angle to force water into the engine’s air intake system.

In any case, this would likely (as you are discovering) be considered accidental damage rather than a warranty issue as the problem wasn’t caused by a fault in the car’s materials or manufacture. Which means you might be better off tackling your insurance company to see if such damage is covered by your vehicle policy. Damage to a vehicle from (flood) water is much more likely to be an insurance job, so start there.

This might sound like a long shot, but are you sure the fuse was okay? Sometimes, these delicate little fuses might look fine, but can still be blown. To make certain, change it for a new fuse anyway and see if that returns things to normal.

However, modern car components like display screens are no different to any other modern electronics (except they live in a much more hostile environment than the TV in your loungeroom). Which means, of course, they can simply die for no apparent reason. At which point, this becomes LDV’s problem as it’s a pretty straight-forward warranty issue. Take the car back to the dealership, tell them the problem and it’s their responsibility to fix as per Australian Consumer Law. LDV can choose to fix the screen or replace it, but it must be returned to fully working condition at no cost to you.
