I own a 2023 Audi e-tron GT Premium Plus, VIN [XXX]. The vehicle was included in NHTSA Recall 24V726 / Audi Recall 931A concerning high-voltage battery modules that may internally short and create a fire risk. Audi previously completed the 931A remedy by installing the advanced HV battery monitoring software. After the recall remedy was completed, the vehicle displayed an Electrical System Malfunction and the Battery Energy Module reported: “Hybrid/high-voltage battery – Cell module 20 faulty.” I have photographic evidence of this fault, although I later cleared the DTC. Audi’s 24V726 documentation states that the final monitoring software is designed to detect future HV battery module anomalies and that affected modules will be replaced when anomalies are identified. I presented the issue to an authorized Audi dealership and requested diagnosis of Module 20 to determine whether it represents the condition associated with Recall 24V726. The dealership refused to evaluate the HV battery because the vehicle has a rebuilt title. I also contacted Audi of America. Audi stated that Recall 931A is already completed because the monitoring software was installed. My concern is not that the software was never installed. My concern is that the vehicle developed a potentially serious HV battery module fault after installation of the recall remedy, and Audi/dealer have not determined whether Module 20 is the battery anomaly the recall monitoring system was designed to detect. I am asking NHTSA to review this as a potential recall-remedy effectiveness and vehicle safety issue, particularly because Recall 24V726 concerns HV battery internal short circuits and fire risk.
