Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2025 Audi S8 appears in the federal record with a single crash‑related complaint and no fire‑related complaints, while each of the top complaint areas is represented by one incident. Compared with the preceding 2021 model year, which recorded eight recalls and 1,106 total TSBs, the 2025 figures are markedly lower and align with the subsequent 2026 year that shows only one recall and 129 TSBs. The complaint trajectory from 2003 through 2021 shows a rise in both complaints and recalls, followed by a decline after 2021, indicating that the 2025 model sits in a downward phase of the arc. No recall count is listed for 2025 in the provided data, so the absence of a reported recall cannot be confirmed. Given the low complaint volume and the recent downward trend, the 2025 model year is not flagged as a high‑risk purchase, making it a reasonable consideration provided no further undisclosed issues emerge.
