Windscreen seal failure

In Suzuki terms they are "Windshield Dams"   

There is a upper dam and two side dams
They are installed on the glass before it is placed on the car and sit outside of the bonded area. Whilst they go most of the length of the top and sides they do not seem to join completely with each other at the sides
The installation instructions for them suggests they are attached (self adhesive??) to the windscreen before it is mounted. As you then install it you are supposed to ensure that they "fit to the roof panel and side panels" so they must have some sort of part in the body they clip or otherwise attach to.

Perhaps a key message in the workshop manual is "Do not apply excessive water pressure"

Parts 2 and 4 in the picture

Haven’t heard of any Gen 4s doing this. My evoque had a rubber seal pop out on the side of the pillar and scared the life out of me on the motorway as it slapped against the window. I think it got disturbed when I had the roof wrapped but equalling it would come off when I pressure washed the car so it could be the dealership has gone too close with the pressure washer. Even though I trust my dealer with my car I still don’t let them wash it and ask them to leave it. 

Well, the dealer just called. Apparently Suzuki are rejecting it as the warranty doesn't cover such things..... back to Customer Services I guess 

Although I need to check, but I thought there was a 5 year bodywork warranty, I'd have assume such a thing might have been covered under that anyway.

Jet washers in the hands of bunkernuts can do some very expensive damage to cars as well as the basics of quick car washing. When used incorrectly water and chemical cleaners can be driven behind all sorts of seals, decorative trim and door locks. I've seen warranty claims for damaged parts rejected for a number of cars of different marques, as jet washing has been carried out irresponsibly. High pressure water jets can be used in a range of applications that include removing scale, corrosion and painted surfaces, cutting steel sheet and accurately cutting complex shapes of automotive carpets. Would you really want to let some unskilled person with a jet washer loose to clean your car with one?

You are of course up against the age old problem of burden of proof. It's OK if you had noticed at the point of collection but it's going to be increasingly difficult after that.

This is a manufacturing problem, not a washing technique issue. We appear to be preparing the gallows for the poor person that washed a car......
We don't even know if they used a pressure washer, it could simply be time, rain and wind pressure, the stuff the front of a vehicle should survive.
