2 faults documented by at least two sources, listed by version then by mileage at onset when known.
2 known faults
Sources report infotainment issues (radio, error messages, software bugs), partly fixed by over-the-air updates (Car Verif, iCarsoft). English-language guides describe a large screen that freezes or restarts and an unstable Apple CarPlay / Android Auto connection, most often resolved by an update or a reset (Autodoc, EVparts4x4).
Atto 3s from 2022 to 2024 were left unresponsive, attributed to a 12 V starter battery that does not keep enough charge to engage the high-voltage contactors (Australian Car Reviews). One guide mentions a parasitic discharge of the 12 V battery on 2022 and 2023 models (EVparts4x4), and one owner reports repeated failures of this battery on a forum (Clean Energy Reviews).
No recurring fault documented for: Atto 3 Evo 313 ch.
An OBD scanner plugged in under the steering wheel shows stored fault codes, even with warning lights off: useful during the test drive.
