Honestly, if the company didn't do basic environmental testing during development, they got off VERY easy.
I don't have an environmental chamber, but I wish I did. Everything I build goes into the fridge for at least a few hours (which means it gets tested at extreme humidity as well as extreme temperature, for better or worse.)
I should put boards on a hot plate at ~60C for a similar length of time, but I didn't do that recently, and I paid heavily for that bit of negligence. Probably wasted 100-200 person-hours at the factory, having them rework a NOR flash part that was fine all along but didn't like being inadvertently overclocked by 2x once the board reached operating temperature in the test area.
