NHTSA Complaint #11619534 — 2021 VOLKSWAGEN ID.4

Over the past month, the car has provided warnings when driving: 1. Front assist has limited availability, 2. ACC unavailable, and 3. Emergency assist is currently not available. Note: the ACC was not engaged when these messages appeared. On October 1 I was driving on a highway at about 65 MPH with adaptive cruise control engaged. The weather was clear. Suddenly the ACC disengaged and the car began to slow. I re-accelerated the car by pushing the accelerator and continued my trip without ACC. No accident occurred but I was surprised when the car began to slow without warning on a major highway at high speed. When it was safe to do so, I pulled over into the breakdown lane to read the messages. The two messages displayed were Front assist has limited availability and Emergency assist currently not available. The picture on the front of the dashboard also indicated that ACC was not available. Over the next few days while driving locally (without ACC engaged), these three messages would periodically appear on the dashboard. I brought the car into a local VW dealer (Wellesley Volkswagen) to have it looked at by the service department. They indicated on the invoice from the visit that they "performed road test. RAND GFF and performed soft configuration of the 5F, front sensor and cluster. Reset all codes with success." The invoice also listed "Concern: 919A vehicle software open. Correction Not available at this time - customer will get notice via mail". I was told by the VW Wellesley representative when I picked up the car that these error messages will likely re-appear until I get the 919A software update, which is not available. These error messages did re-appear yesterday, October 12, while driving locally without ACC engaged. As a side note, I received a recall 919A in the mail from Volkswagen in July 2024 (more than 3 months ago) telling me that a recall repair is not available.
