How does the dealer know the DEF is contaminated?
Do they send it out for sampling?
For 30 years I have done automotive arbitration under the Lemon Law... I would never allow a statement like this to stand without substantiation...
Many times the Dealer/Manufacturer have stood firm and under the Lemon Law were required to buy the vehicle back.
Which brings up another scenario... what about the guy that is required to use DEF and it freezes to a block of ice due to a cold snap?
So far I am unaware of any prohibition of operating a vehicle in extreme cold.
I'm just thinking out loud since I have joined the DEF family last month.
If Ford is selling DEF vehicles in Canada, North Dakota or Alaska... it must accept responsibility for normal operation in these climates.
