2021 AUDI E-TRON

2021 AUDI E-TRON Complaints
I own a 2021 Audi e-tron with approximately 58000 miles. Beginning in March 2026, the vehicle developed intermittent Virtual Cockpit/instrument-cluster problems with blank display. I reported the condition to Audi dealer of Princeton NJ. The vehicle subsequently experienced two dead 12-volt battery incidents and became inoperable. The second 12 volt battery was new. Following the most recent incident, the Audi dealer diagnosed the Virtual Cockpit/instrument cluster as causing a drain on the 12-volt battery and recommended replacement at a cost of approximately $3,500. The replacement part is unavailable, and Audi has provided no estimated delivery date. The vehicle has remained out of service since July 03rd 2026. This condition presents a potential safety concern because failure of the instrument cluster may prevent the driver from reliably viewing speed, warning indicators, vehicle status, range, and other safety-related information. The recurring 12-volt battery discharge may also leave the vehicle unexpectedly disabled. The vehicle is additionally showing an indicated range of only approximately 160 miles at 100% charge. Audi has not established whether this is related to the instrument-cluster failure, high-voltage battery condition, battery-management system, software, or another electrical defect. Audi has not provided documentation of a comprehensive high-voltage battery health and capacity evaluation. Audi issued a recall or service campaign affecting other 2021 Audi vehicles for substantially similar Virtual Cockpit/display problems. However, Audi states that my VIN is excluded and has not provided a technical explanation identifying a different component, part number, software version, supplier, or failure mechanism. I request that NHTSA evaluate whether the recurring instrument-cluster failure and 12-volt battery discharge constitute a broader safety defect and whether the existing Audi recall or service-campaign population should include this car.;
