What Problems Does the 2021 Hyundai Sonata Have?

The 2021 Hyundai Sonata generally enjoys good reliability, but some issues have been reported. Some owners reported issues with the 8-speed automatic transmission, particularly in non-N Line models, with occasional rough shifting or hesitation. Infotainment system glitches, such as screen freezes or connectivity problems, were also occasionally noted. There have been some recalls related to specific components, such as fuel delivery issues or potential problems with the remote smart parking assist system on certain trims. Check the NHTSA website for the most up-to-date recall information.

Long-term reliability concerns primarily revolve around the longevity of the DCT (dual-clutch transmission) in the N Line model, as DCTs can be more sensitive to maintenance and driving habits. While the 2.5L engine is generally reliable, keeping up with scheduled maintenance is crucial to prevent potential issues. Some owners have reported minor electrical problems, but these are not widespread. It is important to check the vehicle's history for any prior accidents or major repairs before purchasing a used 2021 Sonata.

How long will the 2021 Hyundai Sonata last?

With good maintenance, a 2021 Hyundai Sonata can reasonably be expected to last for 150,000 to 200,000 miles or 10-13 years. Proper oil changes, timely replacement of wear items (brakes, tires), and adherence to the recommended service schedule are critical. The engine and transmission are generally durable, but potential weaknesses include the DCT transmission in the N Line needing diligent servicing. Interior materials should hold up well with proper care, although some minor trim pieces could show wear over time. Rust is generally not a major concern, but regular washing, especially in areas with road salt, is recommended. Battery life typically lasts 3-5 years. Hybrid models' batteries are expected to last much longer.

What Technology & Safety Features are Included?

The 2021 Hyundai Sonata is well-equipped with technology. Standard features include an 8-inch touchscreen infotainment system with wireless Apple CarPlay and Android Auto. Higher trims boast a 12.3-inch digital instrument cluster and a 10.25-inch touchscreen. A Bose premium audio system is available. Driver-assistance features are comprehensive, including standard forward collision avoidance assist, lane keeping assist, and adaptive cruise control. Higher trims add blind-spot monitoring, rear cross-traffic alert, and Hyundai's Highway Driving Assist, which combines adaptive cruise control and lane centering.

Optional features include a panoramic sunroof, leather upholstery, ventilated front seats, and a surround-view monitor. The Smart Park feature, available on the Limited trim, allows remote control of forward and backward movement for parking. Safety is a strong point; the 2021 Sonata earned a Top Safety Pick+ rating from the IIHS and a 5-star overall safety rating from NHTSA. These ratings reflect strong performance in crash tests and the effectiveness of its safety technologies. Overall, the Sonata offers a compelling blend of user-friendly tech and advanced safety features.

2021 Hyundai Sonata Prices and Market Value

When new, the 2021 Hyundai Sonata ranged from around $23,700 for the base SE trim to approximately $35,000 for the fully-loaded Limited trim. The N Line started around $33,500. As of late 2024, used market prices typically range from the high teens to the low $30,000s depending on condition, mileage, and trim. Depreciation has been fairly typical for the segment. Factors affecting resale value include mileage, condition, accident history, and trim level. Hybrid models tend to hold their value slightly better due to fuel efficiency concerns. Cars in popular colors and with desirable options like leather seats and advanced safety features command higher prices.

2021 Hyundai Sonata Cost of Ownership

The 2021 Hyundai Sonata is generally economical to own. Insurance costs are typically moderate, aligning with other mid-size sedans. Fuel costs are reasonable, especially with the hybrid variant. Routine maintenance, such as oil changes and tire rotations, is affordable. Repair costs are generally average, although some parts for the N Line model may be more expensive. Long-term ownership costs are manageable thanks to Hyundai's warranty and the vehicle's generally good reliability. Overall, the Sonata presents a budget-friendly option in its class.

2021 Hyundai Sonata Insurance

Insurance for a 2021 Hyundai Sonata is moderately priced, reflecting its status as a Passenger Sedan with strong safety ratings and
reasonable repair costs.

How Does the 2021 Hyundai Sonata Compare to Other Passenger Sedan?

The 2021 Hyundai Sonata competes with the Toyota Camry, Honda Accord, Nissan Altima, and Mazda6. Compared to the Camry, the Sonata offers a more daring design and often undercuts it in price. The Accord boasts a slightly sportier driving experience overall, but the Sonata's tech features are competitive. The Altima is generally more affordable but lacks the Sonata's upscale feel. The Mazda6 offers a more engaging driving experience and a nicer interior, but has a smaller backseat.

In terms of reliability, the Camry and Accord have historically been stronger, but the Sonata has improved. The N Line offers a performance advantage over most rivals, except maybe some of the higher trim Camry and Accord offerings. If reliability is paramount, the Toyota Camry is the strongest contender. If a more engaging driving experience is desired, the Honda Accord or Mazda6 are good choices. If budget is a primary concern, the Nissan Altima is worth considering. Overall, the Sonata offers a good balance of style, features, and value, making it a compelling choice in a crowded segment. The Subaru Legacy is a similar alternative, offering standard all-wheel drive.

The 2021 Hyundai Sonata is ideal for buyers seeking a stylish, well-equipped mid-size sedan with good value. It's worth buying, especially as a used vehicle, given the depreciation it has already undergone. The SEL and SEL Plus trims offer a sweet spot of features and affordability. The N Line is suitable for those prioritizing performance. Consider a pre-purchase inspection to check for any transmission or electrical issues. A new Sonata might be preferable for buyers who want the latest technology and warranty coverage, but a used model offers substantial savings. Overall, the Sonata provides a compelling package for a wide range of buyers.

Great car

I drove 3500 dually diesels for 25-30 years and then went to a Honda ridgeline 2018 new, love it until I drove my wife's new car and decided I needed a car. My best friend had a Hyundai and loved it so I did hours of reviews Hyundai vs many others. All factors considered I decided to test drive a few. All things considered the Hyundai won and a low mileage 2021 caught my eye and I got it. After apps 1000 miles I am so glad I got it. Pros and cons Honda (H) push button start Hyundai (hy) key start, H remote start hy no remote start, H good ride hy better ride, H noisy hy less noisy,H electric keypad with gloves on more user friendly for me, hy parking easier, hy cornering better, H acceleration a bit stronger but hy smoother, both get the job done, I am 74 yo so I understand knobology better than the slow digital control for heat radio etc.,hy wins there- breaks equal, dashboard info hy wins, seems to love Google maps tolerates Waze, I prefer Waze. Pros and cons about not locking keys in car - can't dash out start it w/o leaving key in ignition,physically gettin and out of the vehicle is harder, in a nutshell the things that matter more to me the hy wins so far.The salesman, Lamar was exceptional, a young family man earning a living by hustling but not rushing! Remember Lamar at Southern Auto Group in Newport News VA. Oh and the warranty was winner!

Car review

Great car, but the safety features is to much. It puts emergency break on everytime you park even at the slightest elevation. When you're going down hills it will not let you accelerate to be able to get up the next hill.

Slick looks, jerky power delivery!

The design of this car - inside and out - drew me in. Add to this the comfortable front seats and the pleasant dealer experience, and is was a great start. Like many turbo engine cars, the Sonata is difficult to drive smoothly. Upshifts and downshifts are inconsistent and usually NOT intuitive. Step on the gas pedal...lag, lag, then suddenly power is abruptly present. In normal traffic conditions, when you must continually vary speeds, the 1.6L turbo lag is aggravating. When lifting off the throttle and coasting toward a stoplight, (30 down to approx 18 MPH) the sensation of "drag" or engine braking is annoying, as it scrubs off natural momentum. If you are not sensitive to certain mechanical and momentum-related quirks, the car is great.

2021 Rear doors already rusting.

The rear doors have a drainage problem. They hold water, after a rainstorm. Rust has already begun to form. You open the back doors and several ounces of water run out. Every time. This was an engineering mistake.

Overall, a comfortable vehicle.

My only complaint is the GPS system is not very user friendly. Most of the input is counter-intuitive when trying to enter a destination. Aside from that, the car runs great, handles well and has excellent overall gas mileage. I wish it came with a shift handle rather than the push-buttons on the transmission, but it eventually has sunk in what to reach for. A shift handle can be used without taking one's eyes off the road, but push-buttons can't.

Outstanding vehicle and value

j Just purchased this car in February but have enjoyed it around town and one longer trip with four in the car. It has met my expectations as i drove a Kona Ultimate for the last 3 years. This car has more features and all excellent: the lane corrector has improved; the parking views improves your view around the car and best is the stop and go speed control. Ride and quietness is great and the Bose speakers have garnered accolades from my riders.

Love this car!

This car is comfortable as a driver, passengers say the same. (Rather luxurious) It has lots of technology I'm still learning- most for safety (like lane corrector). It has a solid, smooth ride. I've had it only 3 weeks so dependability is unknown but I've had Hyundai before and it was.
