The VIN is on the listing, the driver’s door jamb, and the bottom of the windshield on the driver’s side.

Does the 2018 Cadillac XT5 have engine problems?

More than most. The pattern is elevated rather than severe. 23 of 66 relevant complaints filed with NHTSA about the 2018 Cadillac XT5 concern the engine, transmission or fuel system (36%), and the largest group is filed under engine (15). For comparison, the 2017 scores 41% and the 2019 scores 22%. On a test drive, check for stalling, loss of power, rough idle, oil consumption or a check-engine light. 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.
