BYD Dolphin: Common Problems & Reliability Guide (South Africa)
Also covers: Dolphin Premium Extended Range, Dolphin Standard Range
These are issues documented for the BYD Dolphin in general - things to check for, not a diagnosis of any particular car. Whether a specific car has one depends on its age, mileage, service history and how it was used.

Symptoms to watch for
- Vehicle found unresponsive after being parked for an extended period (3+ weeks per ev.care) - the same real 12V-drain characteristic documented on the Atto 3 in a related documented issue
- Infotainment system connectivity drops or temporary system lag, reported as minor and generally addressed via software update
- Suspension feels firm, with owners describing a bumpy ride specifically on poor-quality (Tier-2) South African-equivalent road surfaces
- Steering warning light illuminating, with temporary steering stiffness reported by some owners
Rough Repair Cost
Independent workshops typically charge R1 200-R4 500 for this, depending on exactly what's needed. The full independent-vs-dealer breakdown is in a full AutoLytiQs report.
What To Check
The suspension firmness and any active steering warning light ARE test-drive-detectable - specifically drive the example over rough road surfaces and check the dashboard for warning lights. The 12V drain issue is NOT reliably test-drive-detectable for the same reason documented in this platform's Atto 3 card - it manifests only after extended standing.
