Re: 2015 Mustang With 6,000 Miles Bursts Into Flames
I have seen a lot of burn outs with control voltage in the HVAC industry. Because there is so little spark and you generally can't feel it, people tend to be a little relaxed in the security of their terminations. Fortunately in the HVAC industry, signal generation and frequency is much slower so something usually fails long before a fire breaks out. In the automotive industry, control patterns take place in less than a second rather than minutes which result in higher temperatures generated in localized areas much quicker. Adding to the problem is that the connectors are various types of spring type connectors that exist in a very harsh environment creating oxides coatings which increase resistance which will add to any heat all ready generated. Compound this with an increased replacement of metallic components with various polymers that are flame retardant, but can be ignited if temperatures get high enough, and burn at a relatively high temperature results in catastrophes.
Be vigilant with maintaining your connectors. With the increased number of car fires, I'm hoping that someone in the design team is looking for a better way. We're not going to get away from the electronics and we're eventually going to figure out how to make an all electric car that can be quickly charged, without change, these fires will only increase in frequency.
Ever notice that there's so many high performance parts available for GM products?
Did you ever think that maybe they NEED them?
