Checking your own car
A recall applies to a range of VINs, not to every 2020 Cadillac Ct4 built. To confirm whether yours is affected, find the 17-character VIN on the driver-side dashboard or door jamb and enter it in NHTSA's official lookup.
Repairs for safety recalls are free and never expire. A dealer cannot charge you, and cannot refuse on the grounds that the car is old or out of warranty. If one does, call the NHTSA hotline on 1-888-327-4236.
