Battery Cable Problems of Mazda MAZDA6

My vehicle died while I was driving at a low speed into a parking lot. I found out the issue is the positive terminal of the car battery is loose, so the battery cuts in and out. Also, since the positive terminal is loose, the battery acid spills out and corrodes the cable. I have since replaced my battery with a new Mazda car battery, and my mechanic tightened the positive terminal by inserting a metal coin (since the battery harness part has been discontinued). However, I noticed today that there is corrosion on the positive battery cable, so some battery acid is leaking out of my new battery. Also, I noticed that when I start the car, most times the car will die on the first start and need to be restarted in order to stay on. I don't feel safe driving my vehicle b/c I am afraid it will die again while I'm driving it.

I tried to start my car on Sunday morning (March 18th) and it would not start. I purchased a new battery. When I went to install it, I noted that the positive cable had corroded to the point where it could no longer make contact with the battery terminal. Apparently, the wiring needs to be replaced at a cost of approximately $400. Why would this happen at only 39,000 miles? I'm still working through this with the dealer, but wanted to post something as it appears others have had the same issue. I'm definitely not a mechanic but it appears that people might be having problems starting their car, or with batteries needing to be replaced pre-maturely and not realizing that it's due to corroded cables.

I have an 07 Mazda6 that I recently had to replace the 2 battery cables going from the positive terminal to the alternator and the fuse box located next to the battery (it's one cable but it splits in two if you trace it). Several months before I replaced it, I noticed quite a bit of corrosion on the battery terminal. I would clean it off w water & baking powder, but it would come back. Then my car started having trouble starting. I took the batt out and cleaned the terminal, but when I took the cable bracket off of the term it disintegrated from massive corrosion. I eventually traced the corrosion several inches back on the cable while removing the protective rubber hosing. Took it to the dealer who informed me they'd have to order a new wiring harness and replace all the cables in that bundle (there are other various wires that are all "bundled" together) at a cost of well over $1000. Took it to a mechanic who separated the cables from the bundle, removed and replaced w better quality cables. On online forums I've noticed other owners who have the same problem. Looks like Mazda used substandard cable for the positive side. Also, had to replace the battery due to it constantly being drained and not recharged sufficiently. Corrosion was a distinct blue/greenish color. Mazda should address this and replace these. They don't even need to replace the entire wiring harness as the dealer stated!.

Mazda's blueprint for disaster: battery location, battery quality. Overheated , low quality battery spewing acid on critical engine components, corroded wiring, steering, sensors transmission, other parts beyond repair. Washed with water.
