It's a hatchback offering a blend of electric and gasoline power. Key trims include the SE and Limited. Pricing ranged roughly from $26,000 to $34,000 when new.

The Good

What Problems Does the 2021 Hyundai Ioniq Plug-In Hybrid Have?
The 2021 Hyundai Ioniq Plug-In Hybrid generally enjoys good reliability ratings, but some owners have reported issues with the dual-clutch transmission, experiencing occasional jerky shifting or hesitation, especially at lower speeds. Others have mentioned the 12V battery failing prematurely. Some report issues with the infotainment system glitching or freezing.
While not widespread, there have been some reports about the regenerative braking system not feeling as smooth or natural as traditional brakes. Also, premature wear on the brake pads has been reported by some drivers.
Recalls have been issued for previous Ioniq model years for various issues, including potential problems with the high-voltage battery and faulty brake booster. However, it's crucial to check the NHTSA (National Highway Traffic Safety Administration) website for specific recalls affecting the 2021 model year to ensure any potential safety concerns are addressed. Long-term reliability concerns are generally focused on the high-voltage battery's degradation over time, which could reduce its electric range. Regular maintenance and adherence to Hyundai's recommended service schedule are crucial for mitigating these concerns.
