Which ATS years have the most problems?
Complaint volume by model year. Raw NHTSA totals, not adjusted for sales volume or time on the road, so older and higher-selling years accumulate more. Every year links to its full breakdown.
Mixed sentiment with a clear divide between driving dynamics and reliability. The ATS is very frequently praised for its exceptional handling, steering feel, and chassis dynamics, with many owners and community feedback stating it was superior to contemporary
2.0L Turbo (LTG) engine failures: Catastrophic piston and piston ring failures, often around 50,000-100,000 miles (80,000-160,000 km), leading to misfires and requiring engine replacement. Linked to carbon buildup and potential bad piston castings in 2013-2015 models. Frequency: very frequent.
Chronic engine misfires: Recurring across multiple cylinders, often related to ignition coils, spark plugs, and fuel injectors, causing rough idle, stalling, and drivability issues. Frequency: very frequent.
Cadillac User Experience (CUE) system failures: Touchscreen delamination/"shattering," system freezes, unresponsiveness, and complete unit failures. Very costly to replace out of warranty. Frequency: very frequent.
Timing chain system issues (3.6L V6): Potential for failure, especially with extended oil change intervals, noted as a concern around 150,000-160,000 miles (240,000-257,000 km). Frequency: recurrent.
Rear axle seal leaks: Failure every 3-4 years on early model years (e.g., 2013). Frequency: recurrent.
