California vehicle owners have reported persistent engine issues linked to Hyundai fuel injector defects in 2022–2024 models. These problems can cause rough idling, stalling, and increased fuel consumption, creating serious safety hazards.
If your Hyundai has experienced repeated failures despite multiple repair attempts, you may have legal rights under California’s lemon law. At RV Auto Legal Team, we help vehicle owners navigate lemon law claims and hold manufacturers accountable for defective vehicles.
Hyundai Fuel Injector Defects
Fuel injectors are vital to a vehicle’s fuel system. They deliver exact amounts of fuel into the engine’s cylinders, ensuring the right mixture of air and fuel for combustion. By doing so, they optimize engine performance, boost efficiency, and help reduce emissions by providing just enough fuel at precisely the right time.
Defects can result in:
- Engine misfires
- Poor acceleration
- Rough idling or stalling
- Increased fuel consumption
- Long-term engine damage
These defects impact vehicle safety and reliability, and can cause lengthy delays in repairs, leaving you without your vehicle for weeks.
Affected 2022-2024 Hyundai Models and NHTSA Complaint Data
Affected models: Hyundai Tucson (81 complaints), Hyundai Santa Fe (68 complaints), Hyundai Sonata (45 complaints), and Hyundai Santa Cruz (34 complaints).
Common symptoms: Engine misfire, rough idle, and stalling.
Note: NHTSA complaint data is based on publicly available records and may not reflect all incidents.
Many owners report repeated trips to dealerships, often waiting weeks for parts or software updates, only for the issue to recur. These repair delays can disrupt daily life and strengthen your lemon law claim. For more information, contact the RV Auto Legal Team.

Technical Service Bulletins (TSBs) addressing Hyundai fuel injector defects in affected 2022–2024 models:
- TSB 23-FL-002H-1 (June 2023): Addresses misfires caused by leaking GDI fuel injectors in certain 2021–2023 Sonata, 2021–2022 Santa Fe, certain 2022 Santa Cruz, and certain 2021–2023 Tucson models. Provides diagnostic procedures and replacement guidelines.

Legal Actions and Lemon Law Protection
Hyundai has faced:
- Class action lawsuits for defective fuel systems
- Lemon law claims seeking buybacks, replacements, or compensation
California’s lemon law protects consumers when a defect cannot be repaired after a reasonable number of attempts or when a vehicle is out of service for extended periods. Extended downtime for repairs, common with fuel injector defects, strengthens your claim.
Your Attorney Fees Are Covered by the Manufacturers
California drivers are seeing engine issues in 2022–2024 Hyundai models caused by fuel injector defects. California law requires the auto manufacturer to pay your attorney fees, meaning you can pursue your claim without upfront legal costs, even if your vehicle has required multiple lengthy repairs.
Tips to Protect Your Lemon Law Rights During Repair Delays
- Document Everything – Keep detailed repair orders, invoices, and service notes. Include dates and mileage for each visit.
- Record Symptoms – Take photos or videos of misfires, stalling, or rough idling.
- Track Downtime – Note the number of days your vehicle is at the dealership, including waiting for parts.
- Communicate in Writing – Send emails or certified letters to the dealer documenting issues and requesting updates.
- Follow TSB Guidance – Ask the dealership if your vehicle’s repair aligns with the relevant TSB (e.g., TSB 23-FL-002H-1).
- Consult a Lemon Law Attorney Early – The sooner you involve an experienced attorney, the stronger your claim may be, especially if repair delays continue.
