Does My Cadillac CT4 Qualify?
A model's recall history cannot answer that question. Your repair attempts, when the problem was first reported and the vehicle-coverage rules in Maryland or D.C. matter. A lawyer can review those facts rather than relying on a model-wide rating.
If Lemon Law does not cover your circumstances, federal warranty or other consumer claims may be worth discussing. No remedy is guaranteed.
