Li Auto ONE

The model the marque launched with, and the clearest statement of its engineering: an extended-range electric vehicle, where a 1.2 turbocharged petrol engine drives a generator and never the wheels. There is no gearbox between engine and road, no driveshaft from it, and no road load on it at all — so its engine codes are generator-set codes, its operating point is chosen by the control system rather than the driver, and a driveability complaint almost never originates there. Treating one as a conventional hybrid sends the diagnosis to a subsystem that cannot produce the symptom. The recurring genuine faults are the fuel system on an engine that idles at fixed loads for long periods, and the pack's thermal management.

Information, not instruction

CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.

Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:

  • The car — make, model, year and engine. The same fault behaves differently on each.
  • What you measured, not only what you replaced.
  • What actually fixed it — or that nothing did, which is worth knowing too.
