These are common indicators under California's Song-Beverly Act. An attorney reviews the full repair and warranty history before determining whether the firm can take a case.
You bought or leased the vehicle in California.
The problem arose while a manufacturer warranty covered the vehicle.
The dealer has had repeated repair opportunities, or the vehicle has spent significant time in the shop.

Why a warranty isn't enough
Your warranty vs. the lemon law
A warranty is a promise to attempt repairs. The lemon law is what protects you when those repairs never stick.
The manufacturer's warranty
- The manufacturer decides which repairs to attempt.
- It only obligates them to keep trying — not to actually fix the problem.
- When the warranty ends, the manufacturer's repair obligation ends.
California's lemon law
- Kicks in when repeated repairs don't fix a substantial defect.
- Can require a refund, a replacement vehicle, or a cash settlement.
- Your legal claim can survive after the warranty ends — if the defect was reported while it was in force.
- When you win, the manufacturer pays your attorney fees — not you.

Common BMW 4 Series Problems
Your California Lemon Law Rights
Under California's Song-Beverly Consumer Warranty Act, if your BMW 4 Series has a substantial defect that cannot be repaired after a reasonable number of attempts, you may be entitled to:
- Full refund of the purchase price
- Replacement vehicle of comparable value
- Cash compensation (cash-and-keep settlement)
- Attorney's fees paid by the manufacturer
BMW 4 Series Lemon Law FAQ
My 2022 BMW 430i Convertible top is stuck and the dealer cannot fix it. Is this a lemon law case in California?
Yes, a retractable hardtop that fails to open or close properly in your 4 Series Convertible is a substantial defect that impairs the use and value of the vehicle under the Song-Beverly Consumer Warranty Act. The convertible top is a core feature you paid a premium for, and its malfunction significantly diminishes the vehicle's functionality and resale value. If the dealer has made multiple unsuccessful attempts to repair the hydraulic top mechanism, you likely have a strong lemon law claim.
How does the mileage offset work in a California lemon law refund for my BMW 4 Series?
The mileage offset is calculated by multiplying your purchase price by a fraction: the miles driven before the first repair attempt for the defect, divided by 120,000. For example, if you bought your 4 Series for $55,000 and drove 5,000 miles before the first repair visit, the offset would be approximately $2,292. This amount is deducted from your total refund, and all miles driven after the first repair attempt do not count toward the offset.
The BMW dealer says carbon buildup on my 430i's intake valves is maintenance, not a warranty defect. Is this correct under California law?
No, excessive carbon buildup causing drivability issues in the B48 engine is generally considered a design or manufacturing defect, not a routine maintenance item, especially if it occurs within the warranty period. The Song-Beverly Consumer Warranty Act requires BMW to repair defects that impair the use or value of the vehicle. If your 430i is experiencing misfires and rough idle due to carbon buildup under warranty mileage and age, BMW should cover the repair and repeated occurrences may support a lemon law claim.
Can I lemon law my BMW 4 Series Gran Coupe for repeated infotainment system failures in California?
Yes, persistent infotainment system failures in your 4 Series Gran Coupe can support a California lemon law claim if they substantially impair the vehicle's use or value. Loss of the backup camera and navigation constitute safety concerns, while repeated system crashes affect the vehicle's overall usability and the value of the technology package you paid for. Under the Song-Beverly Consumer Warranty Act, these electronic defects are treated the same as mechanical failures.
