There are so many reports of Disco 5s having leaking windscreens that there is clearly a manufacturing issue that LR are failing to acknowledge. On my disco you could move the windscreen if it was pushed outwards, such was the inadequacy of the seal.
The structural integrity of the car is dependent on the windscreen and safety is compromised if the windscreen is loose, or worse, came completely unstuck if the vehicle rolled.
There is a mechanism for complaining to the Driver and Vehicle Standards Agency (DVSA) who can investigate and force a product recall.
We should all complain!
