On the 2026 Audi Q4 e-tron, volkswagen Group of America recalled 2026 Audi Q4 e-tron and Q4 Sportback e-tron vehicles, along with several other VW and Audi models, because the torsion bar inside one or both front seat belt retractors may have been damaged during production. The root cause was traced to component jamming in the ball feeder mechanism during retractor assembly. The torsion bar is the energy-managing element that controls how the belt pays out under crash load; if it fails, the belt may not restrain the occupant properly. Roughly 1,042 units across the affected model range were involved, so this is a narrow production-window defect rather than a broad design fault.

Common Symptoms

  • No perceptible symptom during normal use
  • Seat belt may not restrain occupant properly in a crash
  • Open recall appears on NHTSA VIN lookup

How to Fix

A free recall remedy exists. Dealers replace one or both front seat belt assemblies at no cost under NHTSA 25V638 (Audi campaign 69UM, Volkswagen 694T). Owner notification letters were mailed late October / November 2025. Because the defect is internal to the retractor, there is no visual inspection an owner can perform - verify the VIN against the campaign rather than trying to judge the belt by feel.

Typical repair cost:$0 - $0

On the 2022-2026 Audi Q4 e-tron, the MEB platform keeps a conventional 12V battery alive to run the telematics module, gateway, door handle actuators, MMI and the contactors that connect the high-voltage pack. Owners report the Q4 e-tron going completely dark after sitting only a few days to a few weeks - flush door handles will not extend, the MMI will not boot, and the car cannot be woken even though the traction battery is near full. The DC-DC converter normally tops up the 12V, but it only does so while the car is awake; once the 12V falls below the wake threshold the vehicle cannot bootstrap itself back up. Precursor symptoms are often dismissed as software: 'Electrical system: malfunction' messages, long MMI boot times, and infotainment reboots while driving that disappear permanently once the 12V is replaced. This is distinct from the 2024-2025 on-board charger campaign - it affects cars with no open recall.

Common Symptoms

  • Car completely dead after sitting several days to weeks
  • Flush door handles will not extend; must use the emergency key blade
  • MMI will not boot or takes unusually long to start
  • 'Electrical system: malfunction' warning message
  • Intermittent infotainment reboots while driving
  • Vehicle will not wake or charge despite a full high-voltage battery

How to Fix

Jump or charge the 12V at the underhood terminals to regain access, then have the battery load-tested rather than assumed good. If replaced, the new battery must be coded/registered to the vehicle with a VAS or equivalent scan tool so the charging strategy matches its capacity and age; skipping registration causes premature failure of the replacement. Before spending on a battery, have the dealer check for open campaigns and current software - in some cases the root cause is charging logic or a failed DC-DC converter, not the battery. For cars that sit, a 12V trickle maintainer or driving/charging the car at least every one to two weeks prevents recurrence.

Typical repair cost:$250 - $600
