The buyer question is warranty, campaign and destination support. Start with the candidate facts below and reject any comparison that cannot be tied to a VIN, market and destination.
Decide warranty, campaign and destination support
Treat warranty as a contract tied to a market, seller, vehicle and start date. Separate China-market Song Plus, export-market Song Plus and related SEAL U or SEALION 6 names before comparing coverage. Official BYD pages publish market-specific warranty terms; those figures do not automatically transfer to a parallel import. Obtain written confirmation for the VIN, owner status and destination rather than valuing a generic headline.
Evidence for warranty, campaign and destination support
Retain the warranty booklet, first-sale invoice, registration and service history, battery records and written responses from the relevant distributor. Check open VIN campaigns, maintenance compliance, diagnostic access, software region, app or account support, charging hardware, high-voltage workshop capability and parts routes. Confirm whether a destination dealer can see and support the imported VIN in its own systems.
Export and ownership exposure
Coverage periods, battery-capacity thresholds, commercial-use exclusions and maintenance conditions vary by country. A safety campaign is VIN-specific and should not be used to label every Song Plus defective. A vehicle may be mechanically serviceable but lack telematics, navigation, warranty labour or timely high-voltage parts after export. Price those limits openly.
Apply the decision to a real candidate
Compare a China-market Song Plus with a locally supported SEAL U using two budgets: one assuming no transferable coverage and one using only support confirmed in writing. If a campaign or software action is open, require completion evidence or a named destination route before shipment. Reject a candidate when a safety-critical action cannot be completed by a competent party. Confirm the exact identity through the Song Plus and SEAL U naming guide, then price unsupported items in the maintenance and parts plan.
Build the VIN-linked record
File the candidate under its VIN with separate folders for identity, territory and transfer rules, vin campaign status and commercial records. A replacement vehicle starts a fresh file rather than inheriting the first vehicle's photographs or conclusions.
Common approval mistakes
A persuasive listing does not establish warranty issuer and start, and a brochure cannot settle maintenance compliance for a used or China-market vehicle. Price only the equipment and condition that the evidence proves.
Close the decision
The closing memo for warranty, campaign and destination support should identify the selected VIN, the accepted exceptions and the source behind warranty issuer and start. State whether maintenance compliance was tested, documented or deliberately excluded. Reopen the decision whenever the vehicle, destination, commercial boundary or destination parts and hv support assumption changes.
Independent review for warranty, campaign and destination support
For warranty, campaign and destination support, assign each approval field to a reviewer with the relevant competence. Record candidate evidence for warranty issuer and start, territory and transfer rules, vin campaign status, then obtain destination or commercial confirmation for maintenance compliance, software and diagnostic access, destination parts and hv support where required. Every conclusion should identify its source, date and VIN. If two reviewers interpret a field differently, keep it open until the underlying document, photograph, diagnostic result or written third-party answer resolves the difference.
Arrival controls for warranty, campaign and destination support
Before loading, freeze the accepted VIN, identity, condition, odometer, warning state, keys, accessories and unresolved exceptions. On arrival, compare those records before cleaning, repair, software changes or routine use. Recheck any open item involving maintenance compliance, software and diagnostic access, destination parts and hv support, preserve evidence for a timely carrier or supplier claim, and update the ownership file with actual destination findings and costs.
Assign a reviewer to every high-impact field
No single reviewer normally controls every part of warranty, campaign and destination support. The sourcing contact can establish identity and current availability, a technician can assess territory and transfer rules and vin campaign status, while a destination professional should confirm warranty issuer and start or software and diagnostic access where local rules matter. Record the reviewer, source and date beside each conclusion. Unassigned uncertainty is more dangerous than an identified limitation because nobody knows it still needs resolution.
Close the loop after delivery
Compare arrival findings with the pre-shipment file and update the actual cost of maintenance compliance and destination parts and hv support. Keep photographs before cleaning or repair, preserve diagnostic evidence and notify the responsible party within the agreed claim window. Feeding real arrival results back into the next shortlist improves future inspection thresholds and shipping controls instead of treating each purchase as an isolated transaction.

Does BYD warranty follow every Song Plus to another country?
No. Confirm the exact market terms, sale channel, VIN and destination in writing.
Are Song Plus and SEAL U warranties interchangeable?
No. Related naming does not make market contracts identical.
How should an open campaign be handled?
Confirm VIN applicability and require a documented completion route before shipment.
