Mazda Repair Questions? Ask Mechanics for Answers ASAP
Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
This can be due to a fault with low voltage to the transmission and other electronics due to a loose or corroded battery cable possibly or an issue with the wiring to the computer itself that controls the engine and transmission.This does sound to be electrical since the fault does reset itself and this is the most common cause here in most cases.
If they do not see an issue with the charging and battery and all cables are o.k. the computer itself may be at fault with the wiring needing repaired or replaced.I would also have them make sure all wiring is o.k. leading to the transmission and if a fault is found then the wiring will need repaired to correct this here.In some cases if they are unable to duplicate the fault they may want to hold onto the vehicle for a day or more so they can duplicate it so they can locate and repair the fault.
