Audi Q4 e-tron problems (2021–today)

The only engine of the Audi Q4 e-tron that we have documented, the MEB (ID.3, ID.4, ID.7, ID.Buzz, Enyaq, Born, Q4 e-tron), has high or critical severity faults in the versions it is fitted to. Our verdict for the versions it is fitted to: «With caution».[1][2][3][4][5][6][7]

Outside the engine: The reliability data sheets for the Audi Q4 e-tron contain few reports (4) and several recall campaigns: airbag control unit (68J1), stability control module (45BF) and seat belt torsion bar. There is not enough data to judge real-world reliability outside the engine.[8]

Audi Q4 e-tron rating: acceptable reliability

Calculated using only 6 documented faults and their sources: the most serious and frequent faults weigh more. Limited evidence: it is based on few sources or few documented faults, so it is not included in the rankings. Having few documented faults does not mean it is reliable: it may simply be little studied. How it is calculated

The first label is the most serious fault affecting that engine in this car; the second, our verdict for the versions it is fitted to. Each engine's risk index is calculated only from the faults that affect this car (how we calculate it).

Faults that affect the Q4 e-tron

  1. Critical severityFrequency: OccasionalTraction batteryFaulty modules in the high-voltage battery with fire riskYes: in March 2026 Volkswagen and Cupra recalled around 74,600 ID.3, ID.4, ID.5 and ID. Buzz and around 19,500 Born built between 2022 and 2024, because some battery modules can overheat while charging and, in the worst case, catch fire. It is fixed with software and by replacing modules.
  2. Critical severityFrequency: OccasionalTraction batteryFaulty supplier cells: charging limited to 80% until the battery is checkedIn October 2026 the KBA published new campaigns (93MV, 93MF and 93W4 on the Born) for high-voltage battery cells that do not meet the required quality. While the car is being checked, charging is limited to 80% and must be done outdoors.
  3. High severityFrequency: OccasionalTraction batteryCells with high self-discharge in early cars: service measures 93P7 and 93Q2Some 2020 ID.3s and 2021 ID.4 and Cupra Born may have cells with high self-discharge that reduce usable capacity and trigger a warning. Volkswagen and Cupra fix this with service measures (93P7 and 93Q2) that check the modules and replace faulty ones.
  4. Medium severityFrequency: OccasionalChargingCharging that does not start or cuts out (AC and fast charging)In several MEB cars, owners and the press describe charging that does not start or is interrupted, both on AC and on fast charging. The sources point to the on-board charger, connector locking or software, with no single cause.
