We have just replaced battery at Honda shop for 2015 Fit. We went on 1 week vacation. It is not starting after that. It worked fine until then. Once started with jump start, it works fine while running. Then it didn't start again later in the day. Even 12v charger was showing above 14V in its display.

Battery is failed exactly 3 months after 3 year free replacement warranty. Honda is not doing 100% free replacement instead charging 60% prorated cost. Also replaced start/stop switch and starter in last 1 year. Honda rep says he is seeing check car battery system message. Asked for more details. Do i need to replace alternator now? Things are failing one at a time in the car. I do not have extended warranty.

Thanks

 

Honda shop took back car inside the shop after replacing battery and fixed some loose part. Everything is working fine now. Hopefully, there won't be any issues with alternator. I am seeing 12V to 14.3V on adapter display.

 

Curious, what did they say was loose? I am having the exact issue on my 2015 EX MT. “Check Charging System” accompanied by the TP sensor, asssitive steering, and skid control light come on.

 

I bet they damaged the Honda battery sensor wiring - easy to do.
