Quick answer

For certain Cadillac EVs, DTC U0411 is addressed in official GM/NHTSA communications as part of a GPS-function concern. The verified cause in PIT6425B/C/D is that the telematics module fails to track GPS satellites. This can affect navigation, compass, infotainment clock display, phone projection, Universal Garage Door Opener, and cruise-related functions. Driving and charging status are not yet established by verified evidence.

This page separates verified manufacturer/regulator evidence from supporting material. Unsupported causes, repairs or safety conclusions are not guessed.

1. What does U0411 mean?

For certain Cadillac EVs, DTC U0411 is addressed in official GM/NHTSA communications as part of a GPS-function concern. The verified cause in PIT6425B/C/D is that the telematics module fails to track GPS satellites. This can affect navigation, compass, infotainment clock display, phone projection, Universal Garage Door Opener, and cruise-related functions. Driving and charging status are not yet established by verified evidence.

2. Technical explanation

The supplied diagnostic record’s canonical title and meaning appear to contain warranty text rather than a technical DTC definition. However, official NHTSA-posted Cadillac/GM communications PIT6425B, PIT6425C, and PIT6425D identify U0411 in connection with a telematics module that fails to track GPS satellites, causing a loss of vehicle GPS functions. A separate official communication, PIC6500A, lists U0411 sym00 among multiple DTCs and directs technicians not to replace the controller when those listed DTCs are present; it says to verify the customer concern and wait for an engineering resolution. If none of the listed DTCs are present, the communication directs technicians to follow normal SI Diagnostics.

3. What system is affected?

Verified evidence points to the telematics module and vehicle GPS-dependent functions. A broader system name is not established by the supplied diagnostic record.

4. How serious is this code?

Unknown. The supplied record marks severity as unknown, and the official communications provided do not assign a severity level.

5. Symptoms you may notice

  • Loss of vehicle GPS functions.
  • Navigation concern.
  • Compass concern.
  • Infotainment clock-display concern.
  • Phone Projection concern, including Android Auto and Apple CarPlay.
  • Universal Garage Door Opener concern.
  • Cruise-related concern is listed in the official communication excerpt.

6. Possible causes

  • Verified cause: the telematics module fails to track GPS satellites.
  • Other causes are not yet established by verified evidence.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

Not yet established by verified evidence.

9. What you can safely do

  • Record the displayed symptoms and whether U0411 is stored, including any symptom suffix shown by diagnostic equipment.
  • Arrange diagnosis with a Cadillac/GM service facility and provide the applicable bulletin reference.
  • Do not replace controllers based solely on U0411 sym00; PIC6500A specifically instructs technicians not to replace the controller for the listed DTCs while awaiting an engineering resolution.

10. Step-by-step troubleshooting

  1. For U0411 sym00 and the other DTCs listed in PIC6500A, the official instruction is to verify the customer concern and wait until engineering provides a resolution.
  2. If none of the DTCs listed in PIC6500A are setting, follow normal GM Service Information diagnostics.
  3. PIT6425B/C/D identify loss of GPS satellite tracking by the telematics module as the cause for the GPS-function concern.

11. When to contact service

Contact a Cadillac/GM service facility for diagnosis, especially if GPS-related functions are lost or U0411 is stored. Provide PIT6425D, PIT6425C, PIT6425B, or PIC6500A as applicable.

12. What the service center may check

  • Confirm whether U0411 is present and record its symptom value if shown.
  • Verify the reported GPS-related concern.
  • Check applicability of PIT6425D, PIT6425C, PIT6425B, and PIC6500A using the vehicle’s VIN and current service information.
  • For the DTC list in PIC6500A, avoid controller replacement and follow the bulletin direction while awaiting an engineering resolution.

13. Possible repair or resolution

  • A specific completed repair or engineering resolution is not established by the supplied verified evidence.
  • PIC6500A instructs technicians to wait until engineering provides a resolution for its listed DTCs, including U0411 sym00.
  • PIT6425B/C/D identify the telematics module GPS-satellite-tracking failure, but the supplied excerpts do not establish the full corrective procedure.

19. Frequently asked questions

What does U0411 mean for the listed Cadillac EVs?

The supplied diagnostic record does not provide a reliable technical definition because its canonical meaning contains warranty text. Official PIT6425B/C/D evidence associates U0411 with a telematics module failing to track GPS satellites and loss of vehicle GPS functions.

What functions may be affected?

Verified communications list navigation, infotainment clock display, compass, phone projection, Universal Garage Door Opener, cruise-related functions, and loss of GPS functions.

Should the controller be replaced?

For U0411 sym00 in the DTC list in PIC6500A, the official direction is not to replace the controller; verify the concern and wait for an engineering resolution.

Can I drive or charge the vehicle with U0411?

Not yet established by verified evidence.

Which vehicles are listed in the supplied applicability data?

Cadillac CELESTIQ, LYRIQ, OPTIQ, and VISTIQ in the US for the supplied model-year ranges. Confirm by VIN because bulletin applicability can vary.
