Is the MEB (ID.3, ID.4, ID.7, ID.Buzz, Enyaq, Born, Q4 e-tron) reliable?

There are no documented faults in the electric motor or inverter, but 2026 battery campaigns mean the chassis number should be checked: faulty modules (March) and supplier cells with charging limited to 80% (October). Charging cutoffs are the other recurring fault.[4][5][6]
