Is the 2017 Cadillac ATS reliable?

Reliability is average for the segment when maintained well, with the biggest recurring sore spot being the CUE infotainment touchscreen and some wear-related cooling/suspension issues as mileage climbs.

What are the most common 2017 Cadillac ATS problems?

The most common complaints include CUE touchscreen delamination or unresponsiveness, oil leaks or drivability concerns on some 2.0T models, cooling system component wear (thermostat/water pump), and suspension noises or premature wear on rough roads.

Are 2017 Cadillac ATS maintenance costs high?

Costs are typically moderate-to-higher than mainstream sedans due to premium parts, tires, and labor rates. Staying ahead on fluids, tires, and small leaks can keep ownership costs more predictable.

What are the best years to buy a Cadillac ATS?

Many shoppers prefer later production years after early teething issues, and also prioritize vehicles with documented maintenance and a functioning CUE screen. The best “year” is often the best-maintained example with service records, clean diagnostics, and a strong pre-purchase inspection.

What should I check before buying a used 2017 Cadillac ATS?

Test every function of the CUE touchscreen, scan for stored codes, check for oil/coolant leaks, confirm smooth shifting and consistent engine power, and inspect tires/suspension for uneven wear, clunks, or alignment problems.
