I’ve had my iX for 2.5 years and have logged 122k miles. I haven’t noticed any degradation in battery capacity. Just the normal summer/winter fluctuations (live in Midwest).
Pros: no battery degradation
Vehicle:
BMW
Mileage: 196339 km
Of course, you can get a new battery, and I recently had a new battery 80% covered by the dealer, since this is a very well known and documented problem. (My battery was going on 6 years old, so I felt like the discount made it a good time to replace it anyways. The discount was specifically because it is a known issue, and supposedly the new battery is more powerful and “solves” the problem, per the dealer.)
Pros: more powerful, solves problem
I had one with the battery that lasted just under 12 years.... Old original BMW batteries are built different! Especially if the car is driven regularly.
Pros: lasted 12 years, built different
Same with my 2008 BMW 535d. 900ah and still going strong
Pros: still going strong
Vehicle:
BMW
I had a battery in a 93 BMW last forever like that
Pros: lasted forever
Vehicle:
BMW
I have a 2019 got a discounted replacement battery at the dealer and the new one is much larger (more powerful?).
Pros: larger, more powerful
OEM Subaru batteries and not the best. When it's time for replacement go with a 3rd party battery.
Pros: 3rd party battery better
Cons: OEM not the best
The auto start/stop failed to start the car today while waiting in a left hand turn lane at a red light in traffic. Potentially dangerous situation for anyone. Fortunately the person behind me got out of his car and pushed my car across two traffic lanes to the right curb. The Subaru dealer told me last week when I had the 42k mile maintenance done that the battery was fine based on a battery test. I had specifically asked for the battery to be checked because the starts sounded weak. Now I’m back at the dealer after the failure incident and the diagnoses is a bad battery. It is not safe to have the car automatically shut down on the road when the battery does not have the power to auto start.
Cons: failed to start, weak starts, bad battery
Vehicle:
Subaru Legacy
Mileage: 67592 km
Subaru's factory batteries suck. I've had to replace them in several Subaru's that were only like 2 years old. Doubly tough if the car is just sitting for a period of time between uses.
Cons: factory batteries suck
Vehicle:
Subaru
530e with a little over 20,000 miles shows 10 miles electric range on a nice summer day. It used to show 15 when new. BMW said that the drop was not warranty worthy.
Cons: reduced electric range, not warranty worthy
Vehicle:
BMW
Mileage: 32187 km
