The eighth-generation Hyundai Sonata, launched for the 2020 model year, stands out for its sleek design and advanced safety features. Still, like any modern midsize sedan, the Hyundai Sonata has its share of reliability concerns. Below, we’ll cover the most common issues on the Hyundai Sonata 8th generation model (2020–Current) and explain in detail what owners and prospective buyers should watch for.
Transmission Hesitation and Shifting Issues
Many owners of the 8th-gen Sonata have reported transmission hesitation, especially during low-speed acceleration or when shifting between gears. This concern is most noticeable on the 8-speed automatic and dual-clutch systems found in turbocharged variants like the Sonata N Line. Drivers may feel jerky shifts or delayed engagement when pulling away from a stop. In some cases, a software update or transmission control module reprogramming can improve shift quality, while more severe cases might require mechanical inspection.
Infotainment Freezing and Display Malfunctions
The Sonata’s infotainment system adds modern convenience, but it has been known to freeze, reboot unexpectedly, or fail to recognize smartphone connections via Apple CarPlay or Android Auto. This issue is usually linked to outdated firmware or software bugs rather than hardware failure. Performing regular software updates can help alleviate these issues.
3. Battery Drain and Electrical System Problems
Some Sonata owners have reported premature battery drain, often traced back to components that continue drawing power after the vehicle is shut off, such as the infotainment unit, keyless entry system, or interior lighting circuits. In hybrid models, similar electrical issues can trigger warning lights or reduced hybrid efficiency. Our technicians can test your vehicle to pinpoint the cause, looking for parasitic draw in the system.
Brake Noise and Premature Pad Wear
The Sonata’s braking system offers ample stopping power, but some drivers have noted squealing or grinding noises even with relatively low mileage. This can result from moisture buildup on rotors or early wear of factory brake pads. Regular inspections and brake jobs with high-quality pads and rotors can help maintain quiet, consistent braking performance.
Paint Quality and Exterior Finish Issues
Exterior issues have also been called out by some owners, particularly with chipping or peeling. These cosmetic flaws don’t affect drivability but can impact resale value if not addressed. Hyundai has issued limited coverage for certain paint defects, so verifying warranty eligibility may help offset repair costs.
The Importance of Regular Maintenance
Keeping up with the Hyundai Sonata maintenance schedule is key to preventing many of the problems we listed above. Routine oil changes, tire rotations, fluid checks, and inspections help ensure that mechanical and electronic systems remain reliable over time. For hybrid and N Line models, adhering to manufacturer-recommended service intervals for transmission fluid and cooling systems is especially critical, as neglecting these can shorten component lifespan or trigger costly repairs.
