ANALYSISHow safe is the 2021 Cadillac CT4?
The 2021 Cadillac CT4 received no overall crash-test rating from NHTSA, an absence indicating that the agency conducted no full frontal, side, or rollover evaluations. This lack of primary crash-test data limits a comprehensive safety assessment. Despite the untested status, NHTSA data records two significant recalls for the 2021 CT4. One addresses a critical safety concern: side-curtain airbags that may not deploy as designed, directly compromising occupant protection in a crash. The second recall involves powertrain software, a broader issue affecting numerous GM vehicles. Owners should verify the status of both these recalls. Additionally, two recall campaigns related to lighting module software and the SRS warning lamp were eligible for over-the-air updates; VIN-specific confirmation is necessary to ensure these have been resolved. Seven owner complaints have been filed for the 2021 CT4, with no reported injuries or fatalities. These complaints primarily concern the engine and fuel system, placing the model in a Light burden band for owner-reported issues.
