Finding TXV problems?

Has anyone been seeing new TXV problems?
Ive recently installed a Tempstar 5 ton 14 SEER condenser with an
Aspen TXV coil. (Sorry, the Tempstar matching coil had NO WAY fo
fitting in that space.)  Ran fine about a month. Customer called
saying it wasnt cooling and was making a ton of noise outside. I get
there turned it on and watched it run perfectly and flawlessly for
about 1/2 hr. Subcooling was perfect. Went to the truck to do some
paperwork and customer came out and told me the noise started again.
Sure enough the Internal relief valve opened up in the compressor.
Shut the unit off and back on and it ran for almost 2 weeks fine
again. Same problem yesterday. Gotta change out the TXV this week
which is evidentially closing intermittently. 
Had a Trane dealer close to me tell me the same exact scenario about a
week ago of a new Trane system he installed.
Anyone else found this lately?
