    Leaking windscreen

    Hi everyone it’s been a while since I’ve posted. I have a 21 reg Discovery and the windscreen leaking, its my 2 Discovery and believe or not its the 3 time it’s happened.

    My car has an extended warranty which doesn’t cover the windscreen and Land Rover aren’t interested in fixing it.

    My first Discovery was a new 17 Reg which leaked after 12 months, it was repaired then just after 3 years old when the warranty ran out it started leaking again. I kept the car for 4 years then sold it, then I bought a used 21 Reg when it was about just over 30 months old.

    Family and friends thought I was crazy buying an other Land Rover but then there not broken there fabulous cars. This will definitely be my last Land Rover. Sad

    Is there a group action lawsuit going on, because this issue seems to be happening a lot. If anyone is aware of a group action please let me know.

    I looked into this a while back and found no group was actively pursuing a lawsuit. Although a common fault across several JLR models the nearest I got was someone suggesting it.

    A lot of people have had it fixed foc as a goodwill gesture (myself included) and that seems to have sufficed.

    Coincidentally mine started to leak again last year (after 3 years leak free). I am convinced that mine is on the body side of the rubber, not the glass side. So last weekend I sequentially pulled back the rubber across the top of the windscreen and ran some ‘free flowing’ clear liquid silicon sealant (formulated for this sort of application) in behind. It’s supposed to be self levelling and fills gaps.

    It peed done a couple of nights ago and there was no leak. Now I may have tempted fate by mentioning it but if it gives me another year till I sell it, it will be worth it. And with plenty left in the tube I am up for a repeat application if needs be.

    I know we shouldn’t have to be doing this sort of thing but if it removes one angst in my life it’s worth it.

    I've got a tube of that stuff in my toolbox as my son's BMW X3 developed a windscreen leak earlier this year. It certainly cured the leak and we've had no recurrence since applying it Thumbs Up

    Thanks for the reply and the info about the sealant, I’m still in contact with Land Rover hopefully they might reconsider and fix it. Being still quite an expensive car I think a permanent fix is needed and I would like to keep a bit longer. If it leaks a second time which it will probably do I’ll use the quick fix and get shut asap.👍

    Here in the US, and particularly in the Mountain West, they drop sand in the winter for traction when it's too cold for de-icer, and after large storms when plows leave a skim of ice and packed snow on the road. There are always pencil-eraser sized chunks of gravel in there, and on dry roads at motorway speeds they're little bits of flak that get kicked up ahead of you. Windscreens are consumable items here and covered by insurance after deductible. I've had mine (2017) replaced twice for cracks that spread, plus the original windscreen replaced under warranty after leaking about 4 months in. No windscreen done by a proper professional has ever leaked for me, on any vehicle. My original warranty replacement was handled by Safelite, a company whose only job is auto glass, as have all other windscreen replacements I've had done.

    The original problem with the windscreen was that there was a gap in either the sealant that holds the seal and windscreen to the vehicle creating a space for moisture to migrate between the seal and the window or vehicle, or a gap in the seal itself. In my case, there was actually a half-inch gap in the seal itself - like they cut it too short and it couldn't wrap all the way around the circumference of the windscreen. Had the gap been at the bottom it probably never would have leaked. But it was at the top of the windscreen, in the center.

    Were your windscreens replaced by the same tech? Were the techs Land Rover techs? If so, this is a workmanship issue and they should make it right. If not - probably still a workmanship issue, but you're unlikely to prove it.

    Thanks for your reply stone chips and cracks can happen but poor workmanship is terrible, I’m phoning my local dealer tomorrow to find out what Land Rover have decided.

    If they decline fixing it I will personally contact Land Rover, if I had the funds I would go to a solicitor having 2 Discovery’s and 3 leaks is not exceptable.

    I believe in the US there’s a group action but not in the UK, I’m sure there will be one soon.

    Leaking windscreen

    My local LR dealer has had my car for 2 weeks now I’m waiting for LR warranty department to decide if they’re going to pay for the repair. It’s a joke although I have been given a loan car, if I didn’t have the loan car I would be going ballistic.

    Hi Chalky

    I am still wrestling with the leaking windscreen and wondered when you had your leaks, if any water actually ran down the inside of the windscreen, as opposed to dripping off the roof lining onto the furniture vertically below?

    The reason I ask, is mine doesn’t run down the inside of the glass at all!!

    That suggests to me the leak is between body and seal not glass and seal.

    That being your case, removing and reseating the glass will not cure the leak unless they also fill any gap between body and the factory installed seal bed.

    Just a thought

    Hi Wolfpack when the leak first started it was two small lines of water running down the in side of the windscreen. Then it progressed to 3 drips on to the dashboard 1 each side and the 3rd by the rear view mirror.

    Don’t forget were it’s dripping in doesn’t mean that’s were the seal failed, my first Discovery’s leak was only were the rear view mirror was but water was dripping into the fuse box in the passenger foot well. When the windscreen was taken out during the repair I was shown were the seal had failed, it was where the rear view mirror is located.

    The screen has now been repaired and I wasn’t told how many breaks in the sealant, the dealer got a special windscreen company in to do the repair. JLR warranty department still haven’t decided if they are going to pay for the repair. Hatfeilds the Liverpool dealer after giving me a loan car for 18 days have paid for the repair and they are chasing JLR for the cost.

    The loan car was a Range Rover Evoque, if I would have hired it myself the cost would have been about £1000. I was quoted £125 for the repair which isn’t a big cost but it was the principle, it must be poor design or primer and sealant not fit for purpose because it’s happened to me 3 times.

    When I got my Discovery back I was delighted, I thought to myself I’m back. I still love the car but I think I need therapy.

    Hi Wolfpack again remembering my last Discovery’s leaking windscreen, when I was shown the windscreen the primer had failed on the body. I carnt remember when it started leaking did it run down the inside of the windscreen first before dripping from the rear view mirror.

    All good points, thx.

    My first leak was also running down the windscreen as well as dripping in my lap from the puddle behind the headliner. National windscreen showed me the primer problem on the glass…it was lifting and the attached sealant with it! I then had a period of 2-3 years with no leaks.

    This time there is no water sign on the windscreen inside!
    So I started to think this in another problem and (as you say) water will find the lowest point where ever it enters the vehicle.

    To rule out the “sealant to glassl interface I created my own Silicone Valley Laughing

    I placed beads of silicone in the “gully” every 12” right across the windscreen and trickled water onto the roof from the far/opposite side to the eventually drip point. Kitchen towel was liberally stuck up inside the headliner in the puddle area.

    Satisfied the ingress wasn’t in the first position I removed the first silicone “dam” . I did this for over an hour or more running water then removing each dam in turn and letting it flood to the next one.

    No water got through onto the kitchen towel even when the last dam was right on the edge of the windscreen.

    I am therefore convinced the glass is stuck to the seal/bed and the water must be getting round the back on the bodywork side.




    I then ran water into the gap in the black trim section position A and water immediately wet the kitchen towel. So the point of ingress is somewhere under this trim.





    And I now need some help from any listening in expert to know if these panels should be stuck and sealed to the roof completely, or if water is expected to track underneath.

    Presumably, this strip covers the roof bar access points and I am wondering if water can get through the recess for the roof bars? Not having fitted any or seen how they attach I don’t know if there could be something wrong in that area or if the water is passing through and meeting a gap between the body shell and the JLR bonded windscreen seal/bed?


    Help anyone?

    Might as well add the reply on this thread as it’s more relevant…

    You would not believe it! Or maybe we should being JLR.

    Under the leading edge of the black trim the rubber skirt was cut short (or damaged) on one side.

    The real howler was the windscreen rubber seal was pulled straight rather than following the curve of the body leaving a gap of about 3mm between roof and seal. And of course the gap perfectly coincides with the missing bit of rubber skirt on the trim.

    I’m guessing water just might go down there Whistle

    Having dried and cleaned there and heated it all with a hair dryer, I scraped some of the flowable sealant into the gap and having left it for a few flowable minutes, released the trim to press in place.

    Heaven knows if it fixed it.

    On reflection the one thing I didn’t do was to actually pour some water directly in the gap to see if it disappeared “indoors” but I was losing light and I wanted it dry to reseal.

    So I will just have to wait with bated breath (as I am sure all you readers will be doing Rolling with laughter ) for the next episode of “hold back the waters”.

    Now I know the reason I retired…to look after my LandRover.

    Damn, we're heading into Kirkwall on the ferry tomorrow for the very occasional trip to Tesco (and no doubt, some of the local charity shops) to keep Mrs Mole happy... Neutral

    We'll be away all day so I won't catch up till we get back off the ferry tomorrow night...but it sounds like you've bagged and tagged the culprit from your description. I'll keep my fingers crossed Mr. Green
