2021 Cadillac CT4 — reported problems and evidence

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 (68 records, model years 2020–2026) are most frequently classified under: engine, brakes and driver-assistance systems.
Manufacturer communications (4,878 records, model years 2020–2026) 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
