With 42 NHTSA complaints on record, this defect pattern is well-documented. Owner reports include: “While driving on the freeway, my 2021 Hyundai Tucson SE (72,021 miles) suddenly and without warning lost power and entered limp mode.

I then took it to Pep Boys for a full diagnostic where P1326 was the only code present. The Pep Boys report states the vehicle requires immediate attention. The vehicle remains in limp mode and the check engine light is flashing. The vehicle is not being driven as it cannot safely reach freeway speeds. I contacted Hyundai Customer Care and was assigned Case # XXX. I also contacted a Hyundai dealership who attempted to charge a 225 diagnostic fee despite P1326 being a known Hyundai defect covered under recall/service campaign. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)” (NHTSA Complaint #11724214)

The 2021 Hyundai Tucson has generated 8 NHTSA complaints related to braking, including ABS failures, grinding, reduced stopping power, and warning lights. Owner reports include: “The issue started just before my vehicle had 60,000 miles on it and only occurred every once and a while but, now it happens more often. When braking at low speeds my car makes a hissing/buzzing noise and the pedal goes soft. We got to a dealership when it had 60,420 miles on it. The dealership had it for two weeks saying they have never experienced anything like this issue before. They even contacted Hyundai Tech to help them. No warning lights ever came on and that was my concern. Finally after two weeks they said my tone ring on my driver’s front side was bad and causing a false 0 reading. When I asked why the warning lights didn’t come on they told me everything was working like should. Then after I pointed out that they said it was reading a false zero they were like no that must have been a typo its reading four miles under the rest and that’s causing the abs system to activate. I’m from Ohio so I know what my abs sounds and feels like when it activates. It’s a pulsating feeling not a soft pedal. When my abs truly activates my traction control light comes on. As I stated no lights have ever come on. This issue causes longer stopping times. There hasn’t been any accidents because my wife and I try not to drive it. It’s going to a third shop to try and figure out the issue. Yes the vehicle is available for inspection.” (NHTSA Complaint #11699883)

Engine and cooling problems are among the most serious defects under California’s Song-Beverly Act. Owners of the 2021 Hyundai Tucson have reported issues including stalling, overheating, loss of power, rough idling, excessive oil consumption, and check engine lights that return after dealer repairs. With 4 NHTSA complaints on record, this defect pattern is well-documented. Owner reports include: “The vehicle experienced a catalytic converter efficiency failure that was confirmed by an authorized dealership in January 2025. The dealer indicated the catalytic converter required replacement; however, the replacement was not performed, and the vehicle was returned to service with an unresolved emissions defect. Less than one year later, the vehicle developed recurring emissions system failure, loss of power, drivability issues, and repeated warning indicators. The vehicle is currently out of service while additional components, including oxygen sensors and spark plugs, are reported to be affected. The manufacturer is declining to replace the catalytic converter and is attributing the condition to oil consumption despite the prior unresolved emissions failure. The issue has been confirmed by dealership diagnostics and has resulted in prolonged loss of use of the vehicle. This appears to be a continuing engine and exhaust/emissions system defect that was not properly remedied when first identified and may affect safe operation of the vehicle.” (NHTSA Complaint #11716729)

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 Tucson:
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 Tucson 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.
