We purchased a 36 inch Profile induction 3.5 years ago. 
About a month ago the center burner started working only half, then another burner gives only partial cooking ability and then the two left burners brought up an error message and will not work. After two visits the company we bought it from decided that they would offer a buy out instead of fixing and told us that if we decide to fix it, it probably will break again and we should take the buyout, which only amounts to less than half of a new purchase price. 
So yes, we are very disappointed, but want to add we absolutely loved the cook top, but wish it would of lasted. Now what to do?
