Audi A5 B10 (2024–2026)

Audi A5 (B10, 2024-2026)

Overall Sentiment

Owners express overwhelmingly negative sentiment toward the B10 A5, with many reporting severe software and electrical failures immediately after delivery. The dominant experience is one of deep regret, with multiple owners describing cars that were inoperable within days or weeks, spending months at dealerships without resolution. A small minority report that after initial software updates or battery replacements, the car has been trouble-free, but these voices are far outnumbered by those describing a "nightmare" ownership experience. There is no meaningful distinction between early and late model years in the discussions, as 2025 and 2026 examples both exhibit the same core issues.

Sentiment Confidence Level

High

Frequently Mentioned Competitors

BMW 3 Series, Lexus ES, Lexus IS, Mercedes-Benz CLA, Porsche Macan (as loaner), Mazda 6 (styling comparison)

Positioning vs Competitors

Owners who cross-shopped BMW and Lexus express that they chose the B10 A5 for its driving dynamics and features, but now regret that decision due to reliability problems. One owner notes that the B10's interior reminds them of a Mazda 6, which is not intended as a compliment. Several owners who received Porsche loaners (Macan) while their A5 was in service report enjoying those vehicles more, suggesting Audi's own corporate stable offers a superior experience. No owner states that the B10 A5 is positioned favorably against any competitor in terms of overall satisfaction.

Best Version According to Owners

Insufficient owner data available to declare a consensus. No owner recommends any specific trim or engine of the B10 A5 over another; the only positive mentions of an A5/S5 within the discussions refer to the previous B9/B9.5 generation.

Recommended Configurations

Insufficient owner data available. Owners universally advise against buying or leasing any B10-generation Audi at this time, with one explicitly stating: "Strongly discourage from leasing or buying any of B10 affected Audi's at this time until all SW is resolved."

General Recommendations

Owners strongly recommend avoiding the 2024-2026 B10 A5 entirely, with multiple warnings to "never buy a first model year car." Several owners who traded in a B9 or B9.5 A5 for the B10 express deep regret and advise others to keep the previous generation. One owner who successfully had Audi buy back their car recommends pursuing a B9.5 S5 instead. For those already experiencing issues, owners suggest documenting everything, contacting Audi corporate directly, and pursuing buyback or financial settlement through the finance company (VWFS in the UK). One owner advises keeping the car locked when parked to prevent battery drain from the keyless system constantly searching for the key.

Reported Issues

Remarks

The discussions reveal an unusually high concentration of severe, recurring failures across multiple owners, with some cars spending over 120 of their first 150 days in service. One owner reports that Audi USA denied a buyback request on Christmas Eve after the car had been out of service for 144 of the first 150 days. A dealer technician in the discussions confirms that a new software update (KD3) is being developed for situations where KD2 has not fixed the issues. The root cause appears to be a combination of software bugs and, in some cases, defective hardware modules (thermal management control unit, brake system control module) that software updates cannot address. One owner who works in preproduction notes that 12V battery connections are often not tightened properly at the factory. The discussions also contain extensive criticism of the B10's interior design—piano black trim, capacitive touch buttons, lack of physical controls, and cheap-feeling materials—though these are secondary to the reliability complaints.
