Curious about LNF waterpump failure rate

I realize this probably isn't the place for this, but I'm curious if a lot of the 2.0L turbo (ecotec LNF) motors have ALL needed waterpumps. Almost everyone I know that has more then 45k on their Solstice have had to have their WP replaced and I was wondering what the failure rate was on the HHR and the Cobalt....

I sold my '08 LNF Cobalt at 65k on the orig water pump. No issues.

failure rate for all vehicles is small.

stock water pump on my sky redline at 60k.

100k for for 3 lnf 1 hhr/ 2 cobalt
110k~ 5 lsj for 1 atom/ 3 cobalt/ and a sand rail

maybe location dependent?
