I found out about this the hard way. I purchased my 2019 ISATA 3 on a 2017 MB in May 2018. I picked the unit up at the dealer in Grand Rapids the day after it was delivered. I thought I would have a two year warranty which would have lasted until May 2021.
However, when I took my coach in for servicing this past May, I was told by the dealer that my warranty would expire in November 2021 which means that I only received an 18 month warranty. On a positive note, they did fix the AC freeze up problem at no cost.
