NHTSA Complaints · Active Recalls · California Lemon Law Data
The NHTSA tracks consumer complaints, manufacturer recalls, and safety investigations for every vehicle sold in the United States. These publicly available records are a critical resource for California lemon law cases because they establish patterns of recurring defects.
As of June 2026, the NHTSA has not yet received complaints specific to the 2021 Tesla Model Y. However, this does not mean the vehicle is free from defects. Complaint data often lags behind real-world issues, and many vehicle owners experience problems before they are widely reported. If you are experiencing recurring issues with your 2021 Tesla Model Y, you may still have a valid lemon law claim. You can file your own complaint at SaferCar.gov and check for updates on the NHTSA database.
The 2021 Tesla Model Y has generated 8000 NHTSA complaints and has 21 active recalls. If your 2021 Tesla Model Y has experienced a defect that the dealer has been unable to repair after multiple visits, you may qualify for a full repurchase or replacement under California lemon law. Tesla pays all attorney fees when we prevail. You pay nothing.

California’s Song-Beverly Consumer Warranty Act (Cal. Civ. Code §§ 1790–1795.8) is one of the strongest lemon laws in the United States. It protects buyers and lessees of new and certified pre-owned vehicles that develop substantial defects the manufacturer cannot repair after a reasonable number of attempts.
Under Cal. Civ. Code § 1793.22, a lemon law presumption is triggered when any of the following apply to your 2021 Tesla Model Y:
Once the presumption is triggered, the burden shifts to Tesla to prove the vehicle is not a lemon. Under Cal. Civ. Code § 1794(d), Tesla must pay your attorney’s fees if you prevail — meaning qualified representation costs you nothing out of pocket.
If your 2021 Tesla Model Y qualifies as a lemon under California law, Tesla may be legally required to:
Step 1: Document every repair visit. Keep all repair orders, work orders, and dealer invoices. Each visit counts as a repair attempt, even if the dealer says nothing is wrong.
Step 2: Keep returning for repairs. You must give Tesla a reasonable opportunity to fix the defect. Visit different authorized Tesla dealers if needed and ask for written documentation of each visit.
Step 3: Contact a California lemon law attorney. Once you believe the threshold has been met — 4 attempts for non-safety defects, 2 for safety defects, or 30 days out of service — contact an attorney for a free case evaluation. Under § 1794(d), Tesla pays your fees if you win.
Step 4: Send a demand letter. Your attorney will send Tesla a formal demand letter. Most California lemon law cases resolve through negotiation without going to trial.
Under Cal. Civ. Code § 1793.22, four or more repair attempts for the same non-safety defect, or two attempts for a safety-related defect, triggers the lemon law presumption. Additionally, 30 or more cumulative days out of service qualifies regardless of the number of repair attempts.
Yes. Under Cal. Civ. Code § 1794(d), Tesla is required to pay your reasonable attorney’s fees and court costs if you prevail in a lemon law claim. This means qualified lemon law representation is free to you if your case succeeds.
Yes. A recall is not required to file a lemon law claim. The Song-Beverly Act covers any substantial defect that impairs the use, value, or safety of the vehicle that the manufacturer cannot repair after a reasonable number of attempts. NHTSA complaints support the claim by establishing a pattern, but are not a prerequisite.
California lemon law claims are generally subject to a four-year statute of limitations from the date you discovered or should have discovered the defect. However, you must still be within the manufacturer’s original warranty period when the defect first appears. Contact an attorney promptly to preserve your rights.
