Battery Problems

[Bigal]

Hi guys , new to the forum here. Going to look at a 22 elegance eHRV with 6600 miles tomorrow. Was looking through the battery problems with these cars . Has the problem been sorted by Honda or are people still having problems. Cheers AL.

I had no problems with either the 12v or traction battery on my e: HR-V
I have not heard of any problems with either. To which battery do you refer, and what problems have you heard of?

About 12 posts down there’s a topic about people’s cars not starting due to flat battery and needing jump starts . There’s a link leading to a thread about loads of problems with them and apparently it was to do with the boot lock draining the battery.

There's a software update which seems to have fixed the problem (it took Honda a little while to figure it out). My HR-V suffered a flat 12V battery in December 2022 and the update was applied when the vehicle was being serviced in Feb 23. It's behaved itself since then. Initially, Honda would only pay the dealers to apply the update if the vehicle demonstrated excessive 12V battery drain but I recall reading that the update is now applied to the potentially affected vehicles as a matter of course.

The problem software is the body control module (BCM) and on my HR-V was updated from M0E010 to M0E020. I don't know if a user can access that software version somewhere in the infotainment system menus. Nor do I know if all dealers give the customer a copy of the update report. Mine did.

This issue does seem to be somewhat of a lottery. I've clocked up 23,000 miles of trouble free motoring over two years which has included the car sitting in airport car parks for periods ranging between 8 to 16 nights. The car had it's second service earlier this month and I was warned they'd need it longer to allow for a software update. On the day I asked if I'd notice any difference in the car following the update, I was told I wouldn't and that it was required to resolve an issue with the tailgate though they opted not to mention the resultant battery issue.

The car you're looking at will have had one service and presumably is due a second in coming months, can the dealer/seller confirm the cars had the update?
