Common Issues with Used BYD Seal

The BYD Seal has been highly praised for its technology and value, but like any new-generation vehicle, especially one from a rapidly growing brand, it has a few known issues that potential used-car buyers should be aware of. The information below is based on reports from owner forums and communities.

Build Quality & Mechanical Quirks

While the overall build quality is generally considered high, some owners have reported a few specific issues. These are not widespread but are worth inspecting on a used vehicle.

Suspension Noises

Some owners of the BYD Seal, particularly the Performance models, have reported various squeaks and rattles from the suspension. This can be a minor annoyance and may require a service visit to lubricate components or, in some cases, replace shock absorbers or bushings.

12V Battery Failures

A number of reports indicate issues with the 12V battery, sometimes leading to the vehicle becoming completely unresponsive. While this is often covered by warranty, it's a known weak point that can cause significant inconvenience. It is often linked to loose connections or a battery draining during transport or due to a software glitch.

Tire Wear

Due to the vehicle's weight and the high, instant torque from the electric motors, the BYD Seal is susceptible to accelerated tire wear. Owners, especially those with Performance models and a heavy foot, have reported needing to replace tires as early as 12,000-20,000 km (7,500-12,500 miles). A careful inspection of tire tread and a check of alignment are essential.

Software and Infotainment Issues

The BYD Seal’s software is generally functional, but some users have noted a few persistent glitches and a less refined user interface compared to some competitors.

Software Glitches

While over-the-air (OTA) updates are frequent and address many bugs, some owners have reported issues such as a loss of steering wheel heating, temporary failure of the 360-degree cameras, and unexpected battery drain. Most of these issues are resolved with a software reset or a subsequent update.

Infotainment & UI

The main infotainment screen is large and responsive, but some users find the Android-based user interface to be unrefined or "janky" compared to more polished systems from other brands. While this is largely a matter of personal preference, it's a recurring comment from tech-savvy owners.

Conclusion

The BYD Seal is a reliable and well-built EV for its price point. However, prospective buyers of a used model should be mindful of a few common issues. A thorough inspection should focus on suspension components, the health of the 12V battery, and tire wear. While software glitches can be annoying, they are often resolved through updates. Overall, the BYD Seal represents a strong value in the used EV market, provided a buyer performs due diligence on these known issues.
