Hi I'm new to camping and my wife is concerned about leaving the camping gaz cylinder in the hot car until we can get onsite. Any advice to put her mind at rest?
A few hours won't be a problem as long as it's not in direct sunlight. gas cylinders have to get very hot to burst; you and your wife would have long expired by that time.
Gas bottles are only filled to a max of 80% capacity to allow for this sort of thing.

As Hairywol said, you should have nothing to worry about.
If the ambient temperature was 20 deg C ( 293 deg K absolute) and it rose to 30 deg C (303 deg C absolute) in the car, the absolute temperature and therefore the pressure in the bottle would only have risen by about 3%.

Thats not the calculation for a liquid (which is the case for butane) and the vapour pressure comes into effect, butane is at zero pressure at 0C . At 21.1C the vapour pressure is 16.9psig and at 32C its 29.8psig.
A bit more than that more like a 76% increase but you need that pressure to get the gas out the tank! But the tanks are rated to 30bar which is 435psig so you have a long way to go before there would be an issue. I also ead that it is rated to 87C so I would only run for cover if your car is onfire.
