BMW iX Lemon Law

Yes, significant battery range degradation in your iX is a substantial defect under the Song-Beverly Consumer Warranty Act because it directly impairs the vehicle's use and value. BMW's eight-year, 100,000-mile high-voltage battery warranty covers capacity loss, and if the dealer cannot restore adequate range after repair attempts including battery conditioning and module replacement, your iX may qualify as a lemon. Document your range readings and charging records to establish the pattern of degradation.

Yes, a DC fast charging system that consistently fails to function as advertised is a substantial defect that impairs the use and value of your electric iX under the Song-Beverly Consumer Warranty Act. Fast charging capability is a core feature of the iX that directly impacts its usability for longer trips, and BMW's marketing of 200 kW charging capability sets the consumer expectation. If multiple repair attempts, software updates, and module replacements have not resolved the issue, your vehicle likely qualifies as a lemon.

A recurring rear drive unit failure after replacement is strong evidence for a California lemon law claim under the Song-Beverly Consumer Warranty Act. You should bring the vehicle back to the dealer immediately and request a documented repair order that specifically describes the noise and references the prior drive unit replacement. Then consult with a California lemon law attorney, as a second failure of the same major component typically exceeds the reasonable repair threshold.

No, the Song-Beverly Consumer Warranty Act applies equally to electric vehicles like the iX and traditional gas-powered BMWs. The same standards for substantial defects, reasonable repair attempts, and remedies of refund or replacement apply regardless of powertrain type. In fact, EV-specific components like the high-voltage battery, electric drive units, and charging systems are fully covered by the Act when they fail under the manufacturer's warranty.
