Likewise I got a letter yesterday for my ASX 1.6 ZC-M bought new in September 2016.
Booked in for a replacement relay to do with the Engine Management Unit, tailgate struts and locks on drivers and rear offside passenger doors.
Not had any problems withe car. It's inconvenient but has to have the work done .
Yes I received a letter last Thursday and visited the dealer Friday afternoon.
Advised that it was to do with the struts on the tail gate and the car would be in for about an hour. Mine was first registered July 2016 and is an ASX ZC-M DI-D ( ASX 3 spec) Going in on the 6th March to have the work done.
Otherwise the car is running fine and very pleased with the purchase so far.
