MAX Transit Duo Pro - Cellular Modem stuck in 'Initialization' state

We have a quantity of MAX Transit Duo Pro’s installed in heavy mining vehicles. There is a consistent but random quantity that get stuck in the ‘initialization’ state when booting up and connecting to the cellular network - it is random behavior that we haven’t been able to solve locally. I have been told that it is a supply voltage fluctuation issue by Peplink support however they are supplied with standard 24Vdc, and there is nothing to suggest why power would be an issue.

Can I request that the cellular modules in the Transit Duo Pro receive a firmware update that makes them more resilient to voltage fluctuations? It seems odd that they aren’t more robust. In addition, could a procedure be created so the customer could recover the module instead of waiting for lengthy turn around times with Peplink support in this scenario?
