On July 4, 2026 in the early evening, I was driving in the HOV lane of the freeway when the engine abruptly lost power. There was a warning light that came onto the dashboard but I did not see what it said as I was solely concerned about moving safely off to the shoulder in moderate traffic.

Source: NHTSA, 49 CFR 579.5Is Audi TSB_2079898_1 a recall?
