2021 Volkswagen ID.3 Problems: 7 Known Issues

On the 2020-2021 Volkswagen ID.3, on early ID.3s the 12V auxiliary battery (which wakes the high-voltage system) discharges if the car is left for a couple of days. A fault in an internal communications bus and control modules failing to fully sleep keep draining the small battery until voltage drops below what the HV contactors need to close. The car then becomes completely unresponsive — no lights, no unlock, won't power up. Widely reported on first-year cars before the major software relaunch.

On the 2020-2023 Volkswagen ID.3, iD.3 owners frequently hit CCS2 DC fast-charge problems: the car and charger 'handshake' then drop to a red fault within seconds, the VW app shows "charging error" and the car refuses to charge, or sessions are abnormally slow. Two distinct problems exist — (1) communication/handshake incompatibility with certain charger brands, and (2) slow charging because the HV battery isn't pre-conditioned, so peak power is only reached at low state-of-charge with a warm pack. Ground-fault trips also occur when the connector/port is wet.

On the 2020-2023 Volkswagen ID.3, the central infotainment system built on VW's ICAS3 controller suffers freezes, unresponsive/laggy touchscreen, blank or rebooting central and driver displays, dropped navigation/traffic data and Apple CarPlay/Android Auto disconnects. Early 2020 cars shipped with incomplete software; faults frequently appear within the first few thousand km and some later software versions (e.g. after a 3.x update) introduced new glitches. Because nav, climate and lighting menus are routed through this unit, a freeze degrades several functions at once.

On the 2020-2023 Volkswagen ID.3, owners report intermittent and sometimes hard failures of the rear drive system: dashboard warnings such as "Electric system not working correctly" or "Electric drive: system fault," the car dropping into reduced-power (turtle) mode, or refusing to drive at all. Causes traced at dealers range from networking/communication faults with the power inverter (APP310 pulse inverter) to a blown high-voltage fuse, and in a minority of cases replacement of the entire rear electric motor. Some events resolve on a restart, others strand the car.

On the 2020-2023 Volkswagen ID.3, a distinctive clunk or click from the rear (often rear-right) when moving off from a stop, and on the transition between acceleration and deceleration. The cause is play in the rear driveshaft splines / outer CV joint on the rear-drive platform. It is a known platform issue shared with the ID.4 and Cupra Born and tends to develop as mileage accumulates.

On the 2020-2023 Volkswagen ID.3, the ID.3 uses rear drum brakes, which under regenerative braking are rarely actuated. On low-mileage cars and those parked for long periods, the drums and shoes corrode and can stick or bind, and the electric parking brake can seize the rear wheels. Owners also report brake shudder/judder when finally coming to a stop because corroded friction surfaces don't bite evenly.

On the 2020-2021 Volkswagen ID.3, the €990–€1,250 optional reversible heat pump was found by independent testers (nextmove) to give little or no real range benefit in cold weather, in some early cases making the car less efficient than one without it. VW suggested the system may have been running in dehumidify mode instead of heat mode, and later admitted it had overestimated efficiency at very low temperatures by 10–20%. Owners who paid for the option got a worse winter range than expected.
