One prevalent concern among 2021 Sonata owners is the automatic transmission, which some drivers experience rough shifting or delayed engagement, especially under heavy acceleration. Service records show this is often linked to low or contaminated transmission fluid, emphasizing the need for regular maintenance.
Another issue involves the power steering system, where delayed response or unusual noises can occur, frequently traced to low hydraulic pressure or worn seals. This affects steering precision and driver confidence, particularly in heavier traffic.
Electrical glitches are also reported, including intermittent dashboard warning lights and issues with the infotainment system’s connectivity, which may stem from software bugs or poor antenna alignment.
Additionally, front brake wear tends to be more aggressive than expected, possibly due to aggressive driving habits, requiring earlier replacement than standard. Owners often note uneven tire wear, signaling alignment problems or improper inflation that impacts fuel efficiency and tire lifespan.
Despite these challenges, many 2021 Sonata owners report satisfaction when maintenance is up to date. Staying proactive with scheduled servicing, using OEM parts, and addressing minor quirks early can prevent costly repairs and ensure a smooth driving experience.
