Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
I am sorry that you have not been helped yet. I just came online and saw your question.
Ok, first, I do need to know the year of your CX-7.
This may be a body control ecu issue, smart junction box issue or wiring issue, but I do need to know the year to be able to pull the schematics and go from there
I am sorry but I will have to opt out and see if another expert may be able to help. I have looked over the schematics for yours and am just not seeing where the problem lies. If another expert can help, they will post here
How old is the battery?
Is it the original battery?
Sounds like a low voltage while cranking condition .
Sounds more a body control module issue.
Is it not happening now?
Are you willing to take it to Mazda, if it reoccurs?
That would be wise while the fault is occurring, that you take it Mazda.
Hope they sort it for you.
