What is BYD's Warranty Policy?

[SanHaven]

Currently, BYD's battery warranty policy offers lifetime warranty on the three key electric components (for non-commercial first owners), while the vehicle warranty covers 6 years or 150,000 kilometers. For the three electric systems, BYD provides a lifetime warranty for the Han model, which is extremely rare among all new energy vehicle manufacturers and demonstrates BYD's confidence in its three electric products. Below is more relevant information: BYD battery replacement: According to BYD's warranty terms, batteries can be replaced free of charge only when the battery degradation is abnormal. As for the standard of degradation, BYD has not yet provided an official calculation method, and there are no national regulations on this matter. Currently, the most common industry practice is to replace the battery free of charge if the degradation exceeds 30%. Company profile: BYD Company Limited (referred to as "BYD") was established in February 1995 and is headquartered in Shenzhen, Guangdong Province. The company has over 220,000 employees and operates across four major industries: automobiles, rail transit, new energy, and electronics. It is listed on the stock exchanges in both Hong Kong and Shenzhen.

When I recently purchased a BYD car, I researched their warranty policy, which is quite attractive. Overall, BYD offers a 6-year or 150,000-kilometer vehicle warranty, which is longer than most brands and generally covers the peak usage period. The key is the lifetime warranty on the three core electric systems—battery, motor, and electronic control—which gives me peace of mind. However, there are conditions: it applies only to the first owner, with an annual mileage limit of 30,000 kilometers, and requires regular maintenance; otherwise, the warranty is void. I checked BYD's official website, and this policy aims to encourage long-term use rather than high-frequency driving. If you're planning to buy a new car, make sure to clarify these details to avoid misunderstandings. This lifetime warranty is a real benefit, addressing the major concern of battery degradation.

From a technical perspective, BYD's warranty is quite comprehensive. The 6-year or 150,000-kilometer coverage for the entire vehicle is nothing special. The key lies in the three-electric system—the battery, motor, and electronic control are covered for life, but limited to the first owner and annual mileage under 30,000 kilometers. If the vehicle is transferred, the warranty downgrades to 8 years or 150,000 kilometers. The core of this policy is to protect critical components and reduce user maintenance costs. BYD emphasizes that this must be accompanied by official maintenance records; otherwise, it becomes void. I’ve encountered some users who complain that if they exceed the mileage limit while ride-hailing (e.g., Didi), the warranty becomes uncertain. Overall, this reflects BYD's confidence in product quality and is trustworthy.

As a long-time owner, I have firsthand experience with BYD's warranty. The whole vehicle warranty covers 6 years or 150,000 kilometers, which is sufficient for most cars. The battery warranty is the most impressive—it's covered for life, but with conditions: you must be the first owner, drive no more than 30,000 kilometers annually, and adhere to regular maintenance at authorized 4S shops. I pay close attention to this to avoid missing service deadlines and voiding the warranty. BYD's policies are clear and free of hidden charges, which gives me peace of mind. I believe this policy is a great deal for those planning to keep their car long-term, significantly reducing risks.

For the younger generation buying BYD's pure electric vehicles, the most attractive feature is the lifetime warranty on the three key electric components! A 6-year or 150,000-kilometer warranty for the whole vehicle is nothing new, but having the battery, motor, and electronic control system covered for life is truly a great deal! The condition is that the warranty applies only to the first owner, and the annual mileage should not exceed 30,000 kilometers. This policy eliminates concerns about buying an electric car. BYD's confidence in their product quality makes me happy to support them. I heard they're selling like hotcakes because of this, with young people lining up to get one.

I chose BYD as my family car, and the warranty policy was the deciding factor. The 6-year or 150,000-kilometer whole vehicle warranty is quite decent. The lifetime warranty on the three electric components is even more attractive, but it requires being the first owner, annual mileage not exceeding 30,000 kilometers, and timely maintenance. As a family car, we don't drive frequently, so these conditions are easily met. During maintenance, I always check and keep records to ensure my rights. This is much better than traditional brands, saving both money and effort.
