Starting rattle on Hyundai ix35

I park my ix35 1.7D (2011) on my sloping drive (I back on). The slope means that the rear wheels are about two feet lower than the front wheels. Sometimes, on cold start, there is a terrible rattling noise for about 15 to 20 seconds. There is no pattern to the problem. I regularly check the fluid levels on the car.

Dealer has had it back and no problems found, but it has happened again 4 times in 3 weeks, always on the sloping drive. It is going back in to dealer next Monday.

Do you have any idea what problem could be please, so I can suggest it to dealer?

Because the oil in the engine has tipped to the back, leaving the timing chain and tensioner relatively unlubricated. Better to freewheel it off the driveway onto the flat before starting it.
