russianfrog Posted August 8, 2013 Share Posted August 8, 2013 Hi there, I have had an uncomfortable experience a few days ago, driving back home through the heat of the South European sun: Out of the blue, in town, driving slowly, we hear a "bunk" and then I saw the rear door glass totally shattered! In principle, nothing explains it. I doubt a stone has hit the back door, I don't imagine anyone throwing a stone at us, the terrain was smooth. One possible reason, the clash of temperature: we had been driving all day under a temperature of 35-40°c, with A/C inside (if not then, when?). Could it be the glass did not like it? Anyone experienced the same situation? Here the pic: Good I had duct tape and I found some large format sticker for the way home... Quote Link to comment Share on other sites More sharing options...
pete3000 Posted August 8, 2013 Share Posted August 8, 2013 might be the stress/weight of the door mounted spare twisting the frame onto the glass. If the door /wheel area is corroded one of the internal strengthers may have let go and pushed into the glass on the lower edge. Quote Link to comment Share on other sites More sharing options...
discomikey Posted August 8, 2013 Share Posted August 8, 2013 Pete that looks like a TD5 Type or later improved door (going by the seal and the high level light) so personally dont think it could be that. I cant see the AC making that much difference, and if so why suddenly then? i am baffled to be honest Quote Link to comment Share on other sites More sharing options...

I was drivig on a smooth road, so I can't imagine the frame pushing one way or the other. I'm baffled too! So, should I conclude this isn't very common?

landy andy. Posted August 8, 2013 Share Posted August 8, 2013 Has the door been given a shove recently. Had a mate that hit his spare tyre whilst playing, but was three days later when his screen went bang with the stress. Andy 1 Quote Link to comment Share on other sites More sharing options...
bobed90 Posted August 8, 2013 Share Posted August 8, 2013 We have a 2 year old 110 at work that this happened to. It radomly shattered when we were stood next to it. The vehicle had been parked up for 20 minutes and no one had touched the door. Have had a few others in the past do this also but we always put that down to stone chips or something hitting it inside the vehicle. 2 Quote Link to comment Share on other sites More sharing options...
C18RCH Posted August 12, 2013 Share Posted August 12, 2013 Happened to mine. Overnight in spring. Wasn't a particularly hot day or cold night. Parked in a cul de sac, no traffic, thought it may have been the kids with a fooball but it happened very late night or early morning so unlickely and there was no focal point to the shattering. 1 Quote Link to comment Share on other sites More sharing options...
Dave10101 Posted August 29, 2013 Share Posted August 29, 2013 I had very simular on an LDV van, travelling on a motorway suddenly the rear door glass shattered. No one around, no reason for it. I could only assume a stone or something flicked up by the wheel deflected off something and back into the rear door glass? 1 Quote Link to comment Share on other sites More sharing options...
gti-90 Posted August 29, 2013 Share Posted August 29, 2013 hi, have a look at the connections for the heated rear window, where the wire joins the glass... i had a car rear window bang once and ten minutes before i had knocked the connector off, being in a rush i only just put it back on not quite enough and well it smashed all i could put it down too. but... i dont suppose you would have been using the heater given the conditions unless you knocked the switch? just a idea..

Wangthang Posted February 9, 2014 Share Posted February 9, 2014 Just had the same on a 2010 Utility Wagon rear door window. A short drive then parked up at home - window OK. Returned to the vehicle 10mins later and totally shattered although still in place. Definitely no giggling kids with a catapult around, no extremes of temperature and no use of HRW.

Snagger Posted February 11, 2014 Share Posted February 11, 2014 If I'm not mistaken, that window is actually bonded, not held in by the seal. Glass and steel have different thermal expansion rates, so every change in temperature away from that at which the window was bonded in place will set up stresses in the glass, and eventually the cycles become too much and it'll shatter. It looks like a design flaw - the older type didn't do this because the window was clamped in place by sealant and aluminium strips which allowed enough movement to avert the stresses. I suspect the reason it doesn't happen to bonded windscreens is due to their thickness and the fact that the windscreens are curved. Quote Link to comment Share on other sites More sharing options...
western Posted February 11, 2014 Share Posted February 11, 2014 Td5 rear door glass is held in the seal not bonded to the door. not mention of bonding agents in the parts page http://lrcat.com/31/4/52733 I have a td5 rear door sitting here without glass, it has a flange for the seal, same as the front screen.

Coalcracker Posted May 23, 2022 Share Posted May 23, 2022 2010 LR4: Parked at service station for new battery. Back window just shatters, no contact, no vibration, just sitting there . Quote Link to comment Share on other sites More sharing options...
cackshifter Posted May 23, 2022 Share Posted May 23, 2022 I had one go in an old type rear door just going along a road. Replaced the door with the new type and the glass went on that with it parked on the drive. Just tired of living I guess. Quote Link to comment Share on other sites More sharing options...
