Lane Departure Warning May Be Disabled in 2019 Audi Q8, A7, and A6

Audi Recall Alert: Lane Departure Warning Issue in 2019 Q8, A7, and A6

Audi has identified a new safety defect affecting certain 2019 Audi Q8, Audi A7, and Audi A6 vehicles—specifically those that were previously repaired under recall 25V900. While the original recall aimed to correct a compliance issue, a new software-related problem has now emerged, potentially impacting an important driver safety feature.

What’s the Problem?

According to Volkswagen Group of America, Inc. (Audi), a software error introduced during a previous recall repair (90TV) may have unintentionally disabled part of the vehicle’s lane departure warning system.

Key Details

• The update may have removed the virtual button and icon used to control or display the lane departure warning feature
• Without this interface, drivers may not realize the system is inactive

This issue is now being addressed under a new recall:

• Audi Recall Number: 90TW
• NHTSA Campaign Number: 26V-125

Why This Matters (Safety Risk)

Lane departure warning systems are designed to help prevent accidents by alerting drivers when they unintentionally drift out of their lane. When this system is not functioning—or appears to be missing—it can create confusion.

Potential Risks Include

• Drivers may assume the system is active when it is not
• The absence of controls may cause uncertainty about vehicle safety features
• If other warnings or road conditions are overlooked, this could increase the risk of a crash

This is not a mechanical failure—it is a user interface and software issue—but it still directly affects driver awareness and safety.

What Causes the Issue?

The root cause traces back to the software installed during the earlier recall (90TV).

• The coding used in that update was incorrect for a small number of vehicles
• This resulted in the lane departure warning interface being removed unintentionally
• The issue only became apparent after vehicles received the prior repair

How to Tell If Your Vehicle Is Affected

Drivers may notice the following signs:

• The lane departure warning button or icon is missing from the display
• No visible way to confirm or control the system

Audi also reminds drivers to review their owner’s manual to better understand dashboard indicators and warning messages.

What Is Audi Doing About It?

Audi has announced the following steps:

• Dealers will update the software
• Owner notification letters are expected to be mailed starting May 1, 2026

If your vehicle is affected, this update should restore proper functionality and visibility of the lane departure warning system.

What You Should Do Next

If you own a 2019 Audi Q8, A7, or A6—especially one that previously received recall repairs—take the following steps:

1. Watch for an official notice from Audi.
2. If your vehicle is affected, schedule a software update as soon as possible.

Final Thoughts

Software is increasingly central to modern vehicle safety systems—but as this recall shows, even a small coding error can impact critical features.

If your lane departure warning system appears to be missing or inactive, it is important to address the issue promptly. Staying proactive ensures your vehicle’s safety systems are working as intended—and helps reduce the risk of preventable accidents.
