Common questions
Source: NHTSA, 49 CFR 579.5Is Audi 19IB a recall?
No. A service campaign is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the 19IB repair free?
A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does 19IB cover?
The manufacturer filed it against 5 model years: 2026 Audi RS, 2025 Audi RS, 2024 Audi RS, 2026 Audi RS Q8, 2025 Audi RS Q8. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
