That seems really unlikely to be the problem. Did they ever have the light in their possession, or are they just making up excuses?
For whatever reason, dyno lights have gotten really complex and it isn't surprising that some of them fail. The IQ-X has had some failures, but it's not prevalent enough that I'm concerned it will fail on the road like I am with my Luxos.
