BMW i3 Lemon Law

On range-extender i3 models, the most-reported defect is the REx system faltering under load: as the small gasoline generator engages to keep the battery charged, owners describe the car abruptly cutting power and dropping into limp mode — sometimes on a highway grade — along with overheating and stalling of the generator itself. The result is a car that can't maintain speed exactly when the range extender is supposed to be saving the drive. On battery-electric and REx cars alike, owners also report higher-than-average battery degradation, with some seeing meaningful range loss within a few years, which undercuts the daily usability the i3 was bought for.

Beyond the range extender, i3 owners report the issues common to early EVs: charging problems with the port or cable that make it hard to reliably fill the battery, DC fast-charging that errors out or slows, 12-volt battery drains and no-start conditions, warning messages that come and go, and air-conditioning compressor failures. When a defect like this substantially impairs the use, value, or safety of the vehicle and can't be repaired in a reasonable number of attempts, it can support a lemon claim — including on a used i3 still under BMW's original or certified warranty.

California's Lemon Law fully covers electric vehicles, including the i3's high-voltage battery, charging system, and range-extender generator, and it can apply to used vehicles sold with a manufacturer's warranty. If a substantial defect isn't fixed after a reasonable number of repair attempts — or the car is out of service for an extended cumulative period — you may be entitled to a buyback, a replacement, or a cash settlement, with BMW paying your attorney fees. You do not need a recall to qualify; an unrepaired defect is what matters.

A recall is not automatically a lemon — it's the manufacturer acknowledging a defect and offering a free repair. California's Lemon Law (the Song-Beverly Act) comes into play when a substantial defect can't be fixed after a reasonable number of attempts, or when your i3 has been out of service for 30 or more cumulative days.

If your BMW i3 qualifies, you may be entitled to a buyback (a refund of what you've paid, minus a mileage offset), a replacement vehicle, or a cash-and-keep settlement — and BMW pays your attorney fees on a successful claim, so pursuing your case costs you nothing out of pocket.
