BMW i4 Lemon Law

Talk to a BMW lemon law attorney — your BMW i4 may qualify for a buyback, replacement, or cash settlement.

If your BMW i4 has flashed a "Drivetrain Malfunction," briefly lost power, struggled to charge, or fought glitchy software, those are known i4 issues. If BMW can't fix a substantial defect after a reasonable number of tries, your i4 may qualify as a California lemon.

The Defect

The i4 drivetrain and charging software problem

The i4's most serious defect involves its electric drive motor software. BMW recalled 2022–2025 i4 vehicles under NHTSA campaign 25V395 because the drive-motor software could incorrectly detect an isolation fault and trigger a fail-safe that shuts down the high-voltage system for roughly 15 to 20 seconds — a sudden, unnerving loss of power. Separately, BMW recalled i4s under NHTSA campaign 23V449 for a Combined Charging Unit that may have been assembled incorrectly and needs to be physically replaced. Both remedies are free, one by software update and one by part replacement.

Charging and software are the i4's day-to-day pain points. Owners report a "Drivetrain Malfunction" warning that can cut drive power, DC fast-charging faults (especially at some public stations), and trouble with charge scheduling, station compatibility, and Plug and Charge. On the infotainment side, iDrive quirks are common — frozen cameras, grayed-out driver-assist options, climate or voice controls that ignore commands, and settings that revert after an update.

California's Lemon Law covers an i4 when a substantial defect isn't fixed after a reasonable number of repair attempts, or when the car is out of service for an extended time for warranty work. A recall like 25V395 or 23V449 does not automatically make the car a lemon, and you do not need a recall at all — a drivetrain fault, a charging failure, or a software defect that keeps returning can each support a claim. If your i4 qualifies, you may recover a buyback, a replacement, or a cash settlement, with BMW paying your attorney fees.

Known Issues

Commonly Reported BMW i4 Problems

"Drivetrain Malfunction" warning and sudden loss of drive power (recall NHTSA 25V395)
Combined Charging Unit defect requiring replacement (recall NHTSA 23V449)
DC fast-charging faults and problems with charge scheduling and Plug and Charge
iDrive software glitches — frozen cameras, grayed-out features, reverting settings
The same defect recurring after a software update or repair

Not every BMW i4 is affected. Any substantial, warranty-covered defect that can't be fixed after a reasonable number of attempts — or that keeps your vehicle out of service — may support a claim.

Your Rights

Is Your BMW i4 a Lemon?

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 i4 has been out of service for 30 or more cumulative days.

If your BMW i4 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.

Common Questions

BMW i4 Lemon Law FAQs

Do the i4 recalls (NHTSA 25V395 and 23V449) make my car a lemon?

Not automatically. A recall is BMW's free fix for a known defect. But if the software update or charging-unit replacement doesn't hold, the drivetrain fault returns, or your i4 is out of service for an extended time, that can make it a California lemon — entitling you to a buyback, replacement, or cash settlement, with BMW paying your attorney fees.

My i4 keeps losing power or won't charge — is that enough for a claim?

It may be. A drivetrain fault that cuts power, or repeated charging failures that BMW can't fix after a reasonable number of tries, are substantial defects. Keep your repair orders and note each day the car was down or unusable, then get a free case review.

My i4 charges at home but fails at public fast chargers. Is that a lemon law issue?

It can be. A vehicle that cannot reliably recharge away from home has a defect going to the heart of what you paid for. The difficulty is proving it, because the fault often will not reproduce on the dealer's connection. Insist every visit is written on a repair order with the date, the mileage, and specifics — which station, which network, what error appeared, and whether the session ever initiated. Photos of the error screen at the charger are genuinely useful.

Do over-the-air software updates count as repair attempts?

Often, yes — and this is where owners undercount their history most. If the manufacturer documents a software release as the remedy for a defect you reported, that is generally an attempted repair even though you never delivered the vehicle. Save the release notes and any message identifying an update as the fix for your issue.

How long do I have to file a BMW claim in California?

Longer than on many brands, and it is worth knowing. BMW did not opt into California's AB 1755 procedures, so you are not subject to the one-year-from-warranty-expiration and six-year-from-delivery limits that apply to Jeep, Ford, Hyundai, Chevrolet and Mercedes-Benz. A BMW claim runs on the traditional four-year statute of limitations, measured from when you discovered the defect rather than from the delivery date. An older i4 can still be a live claim where a same-age car from an opted-in brand would already be barred.

My i4 has had several different problems, not the same one repeatedly. Does that count?

Yes. California law does not require every complaint to be the same complaint. A collection of substantial defects that together impair the use, value, or safety of the vehicle can support a claim even where no single symptom recurred four separate times. Service advisors treat each as unrelated; the statute does not.

My i4 has been waiting on a service appointment or parts. Does that help my case?

It can matter a great deal. The law counts days your vehicle is out of service regardless of the reason. Thirty or more cumulative days during the warranty period creates a presumption in your favor. The days need not be consecutive, and being given a loaner does not stop the clock. Keep a written log of every date the vehicle was unavailable.

My i4 has high mileage. Does that kill my claim?

Usually not, and this is a common reason owners never call. The mileage offset is calculated from the miles you drove before your first repair attempt, not from your current odometer — so miles accumulated while the manufacturer worked through the problem do not reduce your recovery.

My i4 is leased. Am I covered?

Yes. Civil Code section 1795.4 gives a lessee the same rights and remedies as a buyer. Restitution on a lease covers your capitalized cost reduction and down payment, the payments you have made, and taxes and fees, and the manufacturer pays off the remaining lease obligation. There is no equity component, so the figure runs lower than a purchased vehicle at the same sticker — but the claim is just as real.

What should I gather before calling about my i4?

Every repair order, including visits closed as no problem found; correspondence identifying a software update as a fix; your purchase or lease agreement; all recall letters; written confirmation of any parts backorder; receipts for towing, rentals and loaners; and a log of days out of service.

What does an i4 lemon law case cost me?

Nothing out of pocket. Under California's Lemon Law, BMW pays your attorney fees on a successful claim, so you can pursue a buyback or replacement without paying upfront.
