Owner reports include: “Dear NHTSA Team, I am writing to report a recurring and distressing issue with my Subaru Legacy 2021 which I believe raises significant safety concerns. Since purchasing the vehicle, I have experienced consistent problems with the battery. Despite replacing the battery five times, the vehicle has repeatedly stopped functioning, including a recent incident where it stalled in the middle of the road. This required me to call law enforcement and a towing service, adding considerable mental and financial stress. These unexpected breakdowns are not only inconvenient but also pose serious safety risks to myself and others on the road. I am concerned that this issue may not be isolated and could affect other Subaru owners as well. I kindly request your assistance in investigating this matter to ensure that appropriate actions are taken to address this potential defect. Please let me know if you need additional information, such as detailed records of the incidents, repair history, or communication with Subaru regarding the issue.

The 2021 Subaru Legacy has generated 5 NHTSA complaints for this defect category. If your vehicle has experienced recurring issues in this area that the dealer has been unable to repair after multiple attempts, you may have a qualifying lemon law claim under California’s Song-Beverly Consumer Warranty Act. Owner reports include: “Three times within a 1 year period, the windshield cracked without an object hitting it. First time in July, 2021, second time in September, 2021, and third time in June, 2022. After the first time, I had the windshield replaced at my own expense. The second time, Subaru completed the replacement at no cost. The third time, Subaru completed the replacement but refused to pay for it, claiming that an object likely hit the windshield. However, the crack occurred overnight while the car was in my driveway. I believe the windshield is obviously defective and I should be remunerated for at least the last replacement and any future such replacements.” (NHTSA Complaint #11474196)

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 Subaru Legacy:
Once the presumption is triggered, the burden shifts to Subaru to prove the vehicle is not a lemon. Under Cal. Civ. Code § 1794(d), Subaru must pay your attorney’s fees if you prevail — meaning qualified representation costs you nothing out of pocket.
If your 2021 Subaru Legacy qualifies as a lemon under California law, Subaru 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 Subaru a reasonable opportunity to fix the defect. Visit different authorized Subaru 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), Subaru pays your fees if you win.
Step 4: Send a demand letter. Your attorney will send Subaru 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), Subaru 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.
