Your Sonata may qualify if…

These are common indicators under California's Song-Beverly Act. An attorney reviews the full repair and warranty history before determining whether the firm can take a case.

You bought or leased the vehicle in California.

The problem arose while a manufacturer warranty covered the vehicle.

The dealer has had repeated repair opportunities, or the vehicle has spent significant time in the shop.

The defect continues and substantially affects the vehicle's use, value, or safety.

Why a warranty isn't enough

Your warranty vs. the lemon law

A warranty is a promise to attempt repairs. The lemon law is what protects you when those repairs never stick.

The manufacturer's warranty

  • The manufacturer decides which repairs to attempt.
  • It only obligates them to keep trying — not to actually fix the problem.
  • When the warranty ends, the manufacturer's repair obligation ends.

California's lemon law

  • Kicks in when repeated repairs don't fix a substantial defect.
  • Can require a refund, a replacement vehicle, or a cash settlement.
  • Your legal claim can survive after the warranty ends — if the defect was reported while it was in force.
  • When you win, the manufacturer pays your attorney fees — not you.

Common Hyundai Sonata Problems

The Theta II 2.4L GDI and 2.0T engines in 2020-2021 Sonata models are prone to catastrophic engine failure due to metal debris from manufacturing contaminating the oil passages, which can cause connecting rod bearing seizure and potential engine fire.
The 2020-2024 Sonata's 8-speed automatic transmission exhibits a shuddering vibration at speeds between 35-50 mph, often traced to premature degradation of the torque converter lockup clutch lining.
The Smartstream 2.5L GDI engine in 2021-2024 Sonata models has been linked to an engine knock or ticking at cold startup caused by piston slap, which can persist and worsen over time as cylinder wall scoring develops.
The 2020-2024 Sonata's advanced driver assistance system, including the Highway Driving Assist feature, intermittently disengages without warning and displays a "Check Forward Safety System" error that dealers have difficulty diagnosing.
The 2020-2024 Sonata's trunk lid assembly equipped with a hands-free smart trunk feature malfunctions frequently, either failing to open or opening unexpectedly while the vehicle is parked, due to faulty kick sensor calibration.

Your California Lemon Law Rights

Under California's Song-Beverly Consumer Warranty Act, if your Hyundai Sonata has a substantial defect that cannot be repaired after a reasonable number of attempts, you may be entitled to:

  • Full refund of the purchase price
  • Replacement vehicle of comparable value
  • Cash compensation (cash-and-keep settlement)
  • Attorney's fees paid by the manufacturer

Hyundai Sonata Lemon Law FAQ

Hyundai has issued a recall for my Sonata's Theta II engine. Does the recall prevent me from filing a lemon law claim?

No, a recall does not prevent you from filing a lemon law claim under the Song-Beverly Consumer Warranty Act. If the recall repair does not fully resolve the defect, or if the engine failure already caused a safety incident, you still have the right to pursue a buyback or replacement. In fact, recalls can strengthen a lemon law claim because they demonstrate that the manufacturer has acknowledged the defect.

My Sonata has been at the dealer for over 30 days total for transmission repairs. Does this automatically make it a lemon?

Under the Song-Beverly Act, a vehicle that has been out of service for a cumulative total of 30 or more calendar days due to warranty repairs is presumed to be a lemon. This 30-day rule applies to the total days out of service across all repair visits, not just a single visit. You should gather all repair orders showing the dates the vehicle was dropped off and picked up to calculate the total days.

Can I recover my attorney fees if I win a lemon law case against Hyundai for my Sonata?

Yes, the Song-Beverly Consumer Warranty Act provides that a prevailing buyer is entitled to recover reasonable attorney fees and costs in addition to the vehicle repurchase or replacement. This fee-shifting provision is one reason many lemon law attorneys take cases on a contingency basis at no upfront cost to the consumer. Hyundai would be responsible for paying your attorney fees if you prevail.

I am the second owner of a 2020 Sonata and the engine is knocking. Can I file a lemon law claim?

If your 2020 Sonata still has an active manufacturer's warranty or is covered by Hyundai's extended engine warranty for the Theta II or Smartstream engine, you may file a lemon law claim as a second owner under the Song-Beverly Act. California's lemon law protects any consumer who purchases a vehicle with an existing warranty, not just the original purchaser. Ensure you report the defect to an authorized Hyundai dealer promptly and keep all documentation.
