Common Problems with the
2023 Audi e-tron SUV

Audi's first electric SUV was facelifted and renamed Q8 e-tron for the 2023 model year: a revised front end, 114kWh battery (106kWh usable) on 55 models with charging power raised to 170kW, longer range and updated software, sold alongside the Sportback until production finished in February 2025.

What changed for 2023

  • •Renamed Audi Q8 e-tron (and SQ8 e-tron) - the MLB Evo generation itself is unchanged
  • •Bigger battery packs: 114kWh gross/106kWh usable on the 55 Q8 e-tron; 100kWh on the 50
  • •DC peak charge rate lifted from 150kW to 170kW; range improved to roughly 370-400 miles WLTP
  • •Revised bumpers, new grille, standard heat pump on most variants

Common MOT watch-outs

  • !Corroded/uneven brake discs from decades of regen-light urban use still write MOT advisories
  • !12V auxiliary battery discharge faults leave late cars unable to wake the charging system
  • !Tyre wear and kerbed 21-inch alloys on heavy (2.6-tonne) SUVs

Buying Tips for 2023 Audi e-tron SUV

  • A 2023-on Q8 e-tron is a materially better car than a 2019-22 e-tron for range and resale
  • Confirm the battery warranty (8 years/100,000 miles) still has coverage left on the specific car
  • Any e-tron Sportback/Q8 e-tron pair under the same entry: check which badging and battery the car actually has
