BYD South Africa — Warranty & Service, Decoded

Written and edited by Ethan Cole, Editor-in-Chief · ✓ Technically reviewed by Daniel Wei Chen — Senior Chinese Automotive Diagnostics & Repair Specialist, Sydney · 22 August 2026.

BYD’s official South African warranty page draws a line through its own showroom: the Dolphin and Dolphin Surf carry 3 years/100,000 km of vehicle cover while every other model carries 5 years — a two-year gap between cars parked metres apart, priced closer than the cover suggests. Here’s the full structure, quoted from the official page.

The official warranty structure

Layer	Coverage	Applies to
Vehicle warranty — tier 1	5 years / 100,000 km	Atto 3 · Seal · Sealion 5 DM-i · Sealion 6 DM-i · Sealion 7 · Shark 6 DMO · Atto 8
Vehicle warranty — tier 2	3 years / 100,000 km	Dolphin · Dolphin Surf — the fine print nobody reads aloud
Power battery	8 years / 200,000 km	All — the market’s longest battery kilometrage among Chinese brands
Drive unit (motor & transmission)	5 years / 100,000 km	All

The two-tier trap, in rand terms. A Dolphin buyer gets two fewer years of vehicle cover than an Atto 3 buyer under the same roof. On the used market this compounds: a 2023 Dolphin is already out of vehicle warranty; a 2023 Atto 3 is not. Nothing on the window sticker says so — the warranty page does, and now this one does too. The clock runs from the purchase-invoice date, not first registration.

What the official page does not say

No battery capacity floor is stated — unlike MG SA’s published 70% threshold. Eight years of cover with an unstated degradation test is a different promise than eight years with a number; ask the dealer for the capacity clause in writing.
Service plans aren’t on the warranty page. At launch, the Atto 3 shipped with a 5-year/100,000 km plan (press-verified, R768,000/R835,000 launch pricing); current per-model plan terms come from your dealer’s offer sheet — get them itemised.

Market comparison — for cross-shoppers

Against the ZA Chinese-brand field: BYD’s battery kilometrage leads (200,000 km vs GWM’s 150,000 and MG’s 200,000-with-a-70%-floor), while its vehicle cover trails (5/100k vs GWM’s 7/200k and Chery’s 5/150k+million-km engine). And the Dolphin tier trails everything. Warranty shopping across these brands is genuinely worth an hour — the spreads are the widest we’ve documented in any market.
