Product review (1 stars): Do not buy a Viking, they are very rude on the phone too.
Ours is now 5 years old and has been nothing but trouble, leaks gas, oven does not come up to temperature, burners click and do not light. One burner no longer functions - turns on but does not adjust and it is hard to tell when gas is turned off.  Door is broken and does not shut fully.  Constantly smells of leaking gas.

We already did our first two rounds of repairs on this awful stove - both at $600 and now we need a third. The service person said all Vikings are terrible stoves and his experience has been all owners are unhappy.

Why there is no class action against Viking is a mystery.  I called them on the phone the first time it broke and they had no intereste in my complaint at all.
