Powertrain and transmission defects directly impair the vehicle’s core function and are generally considered substantial defects under California lemon law. Owners of the 2021 Hyundai Santa Fe have reported harsh shifting, shuddering, slipping, and transmission warning lights. 68 NHTSA complaints have been submitted for this defect category. Owner reports include: “I was about to turn into a 2 lane road and a warning came on my dash, “shifter system malfunction service immediately ” my vehicle was in Drive I was unable to move my vehicle, unable to shift into any other gear. It was sudden with no warning or loss of power prior to the warning and loss of movement.” (NHTSA Complaint #11720840)
The 2021 Hyundai Santa Fe has generated 46 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.

Engine and cooling problems are among the most serious defects under California’s Song-Beverly Act. Owners of the 2021 Hyundai Santa Fe have reported issues including stalling, overheating, loss of power, rough idling, excessive oil consumption, and check engine lights that return after dealer repairs. With 24 NHTSA complaints on record, this defect pattern is well-documented. Owner reports include: “Car misfiring symptoms like rough or shaky idle, hesitation and loss of power during acceleration, stumbling, unusual popping/backfiring noises, poor fuel economy, and a lit Check Engine Light. Felt vibrations / heard sputtering sounds, as if the engine skipped a beat, often becoming more noticeable under load or when accelerating. Sometimes, the issue goes away after restarting the engine.” (NHTSA Complaint #11709148)
Electrical system failures are notoriously difficult to diagnose and repair, which often results in multiple unsuccessful repair attempts — a key element of a lemon law claim. Reported issues for the 2021 Hyundai Santa Fe include infotainment malfunctions, battery drain, warning lights, power window failures, and intermittent starting problems. 18 NHTSA complaints have been filed for this category. Owner reports include: “The rearview backup camera system malfunctioned. The camera was replaced under a safety recall on my 2021 Hyundai Santa Fe. Within four days of the recall repair, the camera continued to fail intermittently, displaying a blank/black screen and not providing a rearview image when the vehicle was placed in reverse. The vehicle is available for inspection upon request. I also have video documentation clearly showing the malfunction occurring. The failure of the rearview camera puts me and others at risk because the system is required to provide visibility behind the vehicle when reversing. When the screen goes blank, I cannot see pedestrians, children, vehicles, or objects behind me. This creates a significant risk of a backing collision, especially in parking lots and residential areas. The vehicle was brought back to the dealership four days after the recall repair because the issue continued. The dealer stated they could not duplicate the issue at the time of inspection and are requesting a diagnostic fee to continue evaluation. However, I have video evidence clearly showing the malfunction occurring after the recall repair. The vehicle has been inspected by the dealership that performed the recall repair. It has not been inspected by police or insurance representatives. The manufacturer has not personally inspected it beyond the dealership performing the recall repair. There were no warning lamps. The issue presents intermittently when shifting into reverse, at which time the display screen fails to show the rearview camera image. The issue first appeared prior to the recall repair and continued within four days after the recall component was replaced.” (NHTSA Complaint #11720472)
Advanced driver assistance system (ADAS) defects — including malfunctioning forward collision warnings, lane keep assist failures, and erratic automatic emergency braking — can create dangerous driving conditions. The 2021 Hyundai Santa Fe has 12 NHTSA complaints for this defect type. Owner reports include: “On 1/1/26 while traveling on the highway with no traffic in front of or right of my vehicle the ADAS emergency brakes applied themselves and slowed the vehicle nearly causing my vehicle to be rear ended. Vehicle is available for inspection. Faulty assistance nearly caused a rear end collision along the highway. Not aware of ADAS being tested inspected although multi-point inspection was done 10/2025. No warnings prior to incident.” (NHTSA Complaint #11708328)

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