2019 Q60 Red Sport - Direct Adaptive Steering (DAS) Recall/Issues?

Vehicle: 2019 Infiniti Q60 Red Sport 400

Hey everyone, I've got a 2019 Infiniti Q60 Red Sport 400, and I'm starting to get concerned about the Direct Adaptive Steering (DAS) system. Lately, the steering has felt inconsistent – sometimes it's super light, and other times it feels unusually heavy or sticky, especially at lower speeds or when parking. It's not a constant issue, but it's enough to make me feel a bit uneasy.

I remember hearing about some recalls or TSBs related to the DAS system in earlier Q50/Q60 models. Does anyone know if these issues extend to the 2019 model year? Is there a specific recall I should be looking for, or is this a sign of a potential failure? I'm worried about a complete steering failure, as this is a drive-by-wire system. Any insights or experiences with DAS problems would be greatly appreciated!

ClearTheCode admin answer:

Your concerns about the Direct Adaptive Steering (DAS) system in your 2019 Infiniti Q60 Red Sport 400 are valid, as it's a critical safety component and has had a history of issues in earlier iterations. The symptoms you describe—inconsistent steering feel, varying from too light to unusually heavy or sticky—are indeed indicative of potential problems with the DAS system.

Here's what you need to know:

  1. DAS System Background: Direct Adaptive Steering is a 'steer-by-wire' system, meaning there's no mechanical link between the steering wheel and the front wheels under normal operation. It relies on electronic signals, with a mechanical backup clutch that engages in case of a system failure. Early versions of DAS (primarily 2014-2015 models) did have recalls and TSBs related to software glitches that could cause a loss of steering assist or unexpected steering behavior.
  2. 2019 Model Year: While the most prominent recalls were for earlier models, software updates and refinements continued. It's possible for later models to still experience issues, though less frequently. There haven't been widespread recalls specifically for the 2019 Q60 DAS system for the exact symptoms you describe, but individual component failures or software anomalies can still occur.
  3. Potential Causes:
    • Software Glitch: The most common culprit, causing miscommunication within the DAS control module.
    • Sensor Malfunction: Sensors that monitor steering wheel input or road conditions could be faulty.
    • Actuator Failure: Issues with the electric motors that control the steering rack.
    • Wiring/Connection Issues: Intermittent electrical problems.
  4. When to See a Shop: Given the safety-critical nature of the DAS system, you should take your 2019 Infiniti Q60 Red Sport 400 to an authorized Infiniti dealership immediately. Do not delay this. They have the specialized diagnostic equipment required to:
    • Scan for DAS-Specific Codes: The system will store specific diagnostic trouble codes (DTCs) that will pinpoint the exact area of concern.
    • Check for TSBs and Software Updates: They can determine if there are any applicable Technical Service Bulletins or software updates for your specific VIN that address these symptoms.
    • Perform System Diagnostics: They can run comprehensive tests on the DAS control unit, sensors, and actuators to identify any failing components. This is not a DIY repair, and professional diagnosis is essential for your safety.
