Do they really honor the 8/100,000 mile battery warranty? In our case YES!!

Thu Aug 22, 2019 11:41 am

Just found out today that our local BMW dealership is going to replace all eight battery cells. Not seen much chatter about them stepping up to the plate and replacing them under warranty, in other prior posts and my research I have found that BMW has done everything to try and avoid this expense. To our surprise, we became one of the lucky few. It was unexpected as we had our air conditioning compressor fail last week (our course we are out of our factory warranty) the new compressor cost us almost $3,000 to replace. Unfortunately, we had to bring it back to the dealership the next day because the A/C had cut out again. They performed a battery capacity procedure (takes 24 hours) and when the result came back, they texted me this, "Based on the results of the capacity test I went forward with a request to the BMW electric mobility team for a High Voltage Battery overhaul They have agreed with my assessment and approved my recommendations. All 8 cell modules will be replaced inside the HV battery pack under the battery warranty coverage. I am currently in the process of getting all the needed parts for the repair ordered. Once I know the availability I can provide a better time frame of when the repair may be completed." There is hope for all 2014 owners. And yes BMW does indeed honor that 8/100,000 battery replacement program.

Do you know what the HV batteries were reading for Kappa, etc.. It would be interesting to know how they determined that the batteries needed to be replaced.

This is a very grey area and I am curious if the signs of a bad battery will be present to us owners or is it a test that BMW does internally with results/readings that don't want to share.

I am going to ask them if I can see the full capacity report, AND do we get a brand new 8/100,000 warranty for the new batteries? If you can think of any more questions I should be asking BMW, please let me know.

I had a service scheduled for today and they didn't include this even though I specifically asked. I spoke with the service manager multiple times and she didn't add it so I asked her to reschedule for another day and with a loaner since it takes a full day to test capacity. In the last two months, our capacity has dropped 25-30% based off the mileage calculator with no difference in how we drive or the accessories we use (AC, radio, etc). Glad to hear they're stepping up without much hassle on your end besides the waiting for parts.

Is your 12V accessory battery 3-4 years old? That seems to be their typical lifetime, and there are some posts that say the guess-o-meter (GOM) starts showing decreased range right before it craps out.....

In general, items replaced under warranty aren't covered by a new warranty with the same conditions under which the items were replaced. Maybe you'd get the greater of the remaining time and distance of the original warranty or a shorter warranty (e.g.. 90 days, 1 year, etc.).

Your replacement battery modules might be populated with used cells that have been tested and matched rather than new cells.

This was the situation with the battery pack warranty of our 2000 Honda Insight, so I'm assuming that BMW's policy would be similar.

Please report what you learn from BMW.

Talked to the service manager yesterday I asked him about getting the results of the capacity report; he replied that our report was different than all others he has seen. Instead of the report coming back with a % of battery life left - it came back with a recommendation for replacement. He forwarded the results to NJ, they reviewed and gave him the green light to replace all the batteries. (with new, not reconditioned).

BTW when posting on this site does your window make clockwise circles around the window that your typing in?

Thanks for posting this. Can you please check and report your current battery Kappa (menu item 13.08 Batt. Kapa. Max. (maximum battery capacity)) at 100% charge. Here are the instructions of how to do that:

Will you get the new higher-capacity cells?

Does this 8-yr warranty apply to second owners?

How many miles are on your car, OP?
