Are RV Safety codes followed and enforced?

[ContinuousImprovement]

Starting this subject in a new thread; hoping for help.
A US owner of a 2018 Canadian manufactured RV discovered a NFPA RV code violation and reported it to the company, January 2018. The violated code was written to assure safe release of the uncontrolled steam pressure, a potentially dangerous event. The violation disables the safety relief valve so an over-pressure event with one owner is probable in the otherwise safe combination forced-air heater and hot water system. The CEO said they've been working on the problem for six-weeks and there would be a recall. It's now been 13 weeks and owners still have no notice asking them not use the heater or minimally be careful. Is this timing normal and acceptable? Would a government watchdog speed the process up?

The customer recently found an electrical defect that he deems more hazardous. The customer has reported the defect to the dealer and also wants to report to the proper government authorities to speed response.
1) The NHTSA was contacted and they are only interested if injury has already occurred.
2) FTC will only take action if hundreds of people file complaint.
3) Transport Canada doesn't handle RV plumbing and electrical violations and they won't help because he's not a Canadian citizen.
4) Health Canada is a maze and again, he's not Canadian citizen.
5) US and Canadian Fire Marshalls have been told but they aren't sure they have jurisdiction and so far have not said they can help.

I'm seeking the industry's help since the manufacture is not willing. There are many RV manufactures in Canada and USA each with many engineers. Will one of them provide a flesh and blood contact in a US government agency that can hear a list of safety issues and determine their disposition? Thanks
