Cadillac CT6 — reported problems
CarFaultIQ holds 6,188 evidence records for the Cadillac CT6 (2016–2020), drawn from official sources and owner complaints.
What owners report: issue areas
Owner complaints are classified by the system they concern: 186 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.
- Powertrain (transmission & drivetrain)76 (40.9%)Official recall records for this system: 3, covering model years 2016–2020.
- Brakes16 (8.6%)Official recall records for this system: 3, covering model years 2019.
- Driver-assistance systems14 (7.5%)
- Engine12 (6.5%)
- Electrical system10 (5.4%)
- Fuel system8 (4.3%)
Other / uncategorized: 8 classifications (4.3%) were not assigned to a specific system by the source. They are counted but not treated as an issue area.
These are counts of records held by CarFaultIQ, not a failure rate. More records can simply mean more vehicles were sold or more owners reported. No vehicles-in-service figure exists in this data, so no reliability or risk score can be derived from it.
What the records are about, by source
Each source is kept separate: owner complaints, recalls, manufacturer communications and investigations are different kinds of record and are never added together. All model years.
- Owner complaints (128 records, model years 2016–2020) are most frequently classified under: powertrain (transmission & drivetrain), brakes and driver-assistance systems.
- Manufacturer communications (6,031 records, model years 2016–2020) are most frequently classified under: equipment & accessories, electrical system and engine.
"Most frequently classified under" reports how the records are filed by the source. It is not a finding about causes, and a record can be filed under more than one system. Read the individual records
Mileage reported when the issue occurred
- 54reports included a mileage
- 33,687average of those mileages
This is the mileage owners recorded at the time they reported, not an expected failure mileage and not a prediction for any individual vehicle. The lowest and highest figures on record are not shown: they are unverified odometer entries that include zeros and implausibly high readings, so they would not describe a real range. A median is not shown either, because the stored figures are group totals and a median cannot be recovered from them.
Evidence by model year
Records held per model year. Select a year to narrow this page to it.
- 2016 1,382 records for 2016
- 2017 680 records for 2017
- 2018 702 records for 2018
- 2019 893 records for 2019
- 2020 764 records for 2020
Counts are not adjusted for how many vehicles were sold in each year, so a taller year is not necessarily a worse year.

Diagnostic codes found in evidence for this vehicle
These codes appear by explicit identifier in official records matched to this exact model and year.
A code appearing in a record means the code was named in that document. It is not a diagnosis of this vehicle, not a fault this vehicle has, and not an indication of urgency. Diagnosis requires reading live data from the vehicle.
