2015 Cadillac CTS problems: engine and transmission complaints and recalls
47% of relevant owner complaints filed with NHTSA on the 2015 Cadillac CTS are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.
Worse than 59% of the 1,790 model years we track (2010–2023).
Does the 2015 Cadillac CTS have transmission problems?
Owner complaints say yes, as a model-year pattern. 22 of 48 relevant complaints filed with NHTSA about the 2015 Cadillac CTS concern the engine, transmission or fuel system (47%), and the largest group is filed under power train (19). For comparison, the 2014 scores 65% and the 2016 scores 45%. On a test drive, check for shuddering, slipping, delayed or harsh shifts, or a whine at speed. This describes the model year, not any one car: a well-maintained or already-repaired example can be fine, and a clean model year can still have a bad car in it.

Yes. NHTSA lists 1 recall campaign on the 2015 Cadillac CTS involving the engine, transmission or fuel system, out of 4 in total.
