Tesla Model 3 Long Range Lemon Law

Yes, if the range loss exceeds Tesla's warranted battery capacity retention, this constitutes a failure to conform to warranty under the Song-Beverly Act. Tesla warrants the Model 3 Long Range battery for 8 years or 120,000 miles with 70% retention. A 20% loss in two years projects well beyond the warranted threshold and indicates a defective battery pack that Tesla must address or face a lemon law buyback claim.

A software update that substantially reduces your vehicle's Supercharging capability can constitute a defect under the Song-Beverly Act if it impairs the vehicle's use or value. Tesla sold your Model 3 Long Range with a specific Supercharging speed as a key feature, and unilaterally degrading that capability through a software update may violate the express warranty. Several class actions and individual lemon law claims have been filed on this exact issue in California.

You should report the defect to Tesla immediately and request a repair appointment, as the Song-Beverly Act requires you to give the manufacturer a reasonable opportunity to repair the vehicle. The statute of limitations for lemon law claims in California is four years from the date you discovered or should have discovered the defect. However, you should not wait, as continued driving with a malfunctioning charge port increases the mileage offset deducted from any future refund.

A consistent and substantial shortfall between advertised range and actual real-world range may qualify as a defect under the Song-Beverly Act if it constitutes a nonconformity with the manufacturer's express warranty. Tesla advertises an EPA-estimated range for the Model 3 Long Range, and if your vehicle consistently falls 30% below that figure under normal driving conditions, this represents a substantial impairment of value and use. Document your actual range data using the vehicle's trip meter and energy consumption graphs over multiple charge cycles.
