Audi filed this with NHTSA as a service bulletin dated Mar 24, 2026, received Apr 7, 2026, about the power train. It names 66 model years (2018–2024). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What owners reported
Source: NHTSA complaint databaseOwners of the 66 model years this bulletin names have filed 810 complaints with NHTSA since 2015. 106 of them name Power Train — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
On the 2019 Audi Q8, the 21 owners who gave an odometer reading for Power Train reported it at a median of 4,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The contact owns a 2024 Audi A6. The contact stated that while driving at an undisclosed speed, the vehicle suddenly came to an abrupt stop. The contact stated that everything turned off except for the instrument panel, which displayed an accident warning light. The vehicle was not in a crash, but all the features became inoperable.

Auto start/stop is turning off the engine and putting the car in neutral before the vehicle is completely stopped. If you need to accelerate suddenly to clear an intersection, it takes a few seconds for it to start back up and move the vehicle. Like most people do, the throttle gets pressed harder in the hopes of the vehicle moving.

I was driving my vehicle when the engine surged and then a transmission warning light came on and there was an immediate and complete loss of drive power. After the vehicle glided to a stop, there was no drive transmission in either forward or reverse. There was no pre-warning and no earlier incidence that led up to this issue.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Audi TSB_2070349_6 a recall?
No. A service bulletin 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 TSB_2070349_6 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does TSB_2070349_6 cover?
The manufacturer filed it against 66 model years: 2024 Audi A6, 2023 Audi A6, 2022 Audi A6, 2021 Audi A6, 2020 Audi A6, 2019 Audi A6 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
