Hi Larry, recalls, fixes, & even parts availability is long gone.
Not much of a health hazard, but a possible fire hazard on the liquid cooled models.
There never was a recall or repair plan for coolant leaks.
Seems like there should have been, as problems began early and weren't uncommon:
Some people did receive repair or replacement, but I haven't heard of anything like that in more than a year (likely closer to two years).
Now, we are talking about a nearly 7 year old machine, currently classed as vintage.
Except in the state of California, there is no service availible for that machine.
