Yeah it could be one of the possiblities temp wise, can't think of any other reason really, there's little to no movement in that area, highly unlikely a foreign object hitting it. I'm pretty sure it's cracked under its own. I rang my Ford garage who did my 3rd service and MOT but got transfered in the end and think it was just a general call centre. It's booked in to get looked at tomorrow morning and get the Body Shop to look at it too, that's all thats been mentioned really just look. Could be just one panel to replace i don't know if it's the total roof out. Fingers crossed it goes ok and get done under warrentyWonder if it's to do with how hot and dry of a summer we've had the past few years? Maybe could be what's affecting the window seals on some models too.
Then again I'm no engineer and it's purely speculation. Best of luck with ford!
Really....... Is the car that brittle that an "acorn" could knacker it ?I'd say it's highly likely to be hit by a foreign object, not unlikely.
Is the time of year where acorns are falling, among other plant life, branches...birds dropping them or other stuff they've picked up...stones thrown up from other road users. A whole host of likely possibilities.
Hi AMcHit one at 60mph and then tell me it doesn't hurt you...
For reference, a 2.5 gram dust cap on a Veyron ends up weighing the equivalent of 16lbs at full speed...that's just over 7kg.
you’ve made some good comments there like.As I've never remotely entertained the notion of having a pano roof I have no reference points for where exactly on the roof that crack is. Could you therefore please give me a steer, especially if the crack is central (to the width of the car) and if the panel has any, even very faint, curve in it.
The reason I ask is that crack is suspiciously straight, more of a faultline than the usual chaos of a random smash. Faultlines take distinct paths, usually directly linked to where the pressure comes from.
If its curved at all and, speculating a possible cause here, were the panel to be under lateral compression (a faulty 'pinched' fit for example) the centre of that curve would be the point of maximum stress. Under tension it'd still take something to make it go, but that is where it would go.
Now. If its central the theory still stands up...if its not then please move along, nothing to see here 😄
As for acorns I'm sure this has come up before on here... they can make one helluva bang. I've been around a lot of gunfire in a 'past life' and when one hit my screen I was 'right back in 'Nam' 😳
Hello AMc,So you're denying that tiny little stones don't crack solid glass windscreens... Okay 🙂
Acorn was just one example, there are copious other potential objects that it could have been. A stone for one.
