- Reliability (3)Reliability ratings for the ATS are generally average. Some owners have reported issues with electronics and the CUE system, but major mechanical problems are not widespread.
- Maintenance (3)Maintenance costs are typical for a luxury brand. Parts and specialized labor can be more expensive than for mainstream vehicles, but routine maintenance is manageable.
- Technology (3)The CUE infotainment system can be a bit laggy and unintuitive at times, though it offers a decent range of features for its era. Overall tech is functional but not class-leading.
- Comfort (4)Seats are supportive for longer journeys, and the cabin is generally quiet. Ride quality is firm but not overly harsh, striking a decent balance between sportiness and comfort.
- Dynamics (3)The 2.5L engine is adequate for daily driving but lacks the punch found in higher trims or competitor offerings. Handling is competent and balanced, offering a good feel for the road.
