| 2009 | Recommended | 7 | Scattered powertrain complaints (rear differential/driveline noise, transfer-case and drive-axle concerns) on the all-wheel-drive first-generation cars, though overall complaint volume is low and these are the most settled first-gen years.; Assorted electrical faults (window, lighting, and accessory circuits) reported intermittently; generally minor relative to the later second-generation cars. | Full report ↗ |
| 2016 | Caution | 6 | Projector low-beam headlights deteriorate and grow dangerously dim over time (hazing, internal moisture, reflector breakdown); GM/Cadillac acknowledged it as a known model fault and the car becomes effectively unusable at night until the units are replaced.; Rear suspension toe-link recall (15V-621 / 16V-...): a toe link can loosen or separate, allowing loss of steering control at speed; affected vehicles were recalled for inspection and replacement.; CUE touchscreen infotainment freezes, lags, fails to respond, or develops surface cracks/delamination, sometimes disabling climate and audio controls. | Full report ↗ |

| 2013 | Caution | 5 | Projector low-beam headlights fade to a dangerously dim output over time (lens hazing and internal moisture); a widely reported, GM-acknowledged fault that makes night driving unsafe until the headlamp assemblies are replaced.; Premature brake wear and weak brake feel; owners report rotors and pads needing replacement at low mileage and occasional brake-pedal complaints.; Six-speed automatic shows hesitation, harsh or delayed shifts, and occasional shudder; some owners report driveline clunk and speed-control concerns. | Full report ↗ |
| 2012 | Caution | 5 | Projector low-beam headlights fade to a dangerously dim output over time (lens hazing and internal moisture); a widely reported, GM-acknowledged fault that makes night driving unsafe until the headlamp assemblies are replaced.; Premature brake wear and weak brake feel; owners report rotors and pads needing replacement at low mileage and occasional brake-pedal complaints.; Six-speed automatic shows hesitation, harsh or delayed shifts, and occasional shudder; some owners report driveline clunk and speed-control concerns. | Full report ↗ |
| 2006 | Caution | 5 | Electrical gremlins across the body and accessory systems (warning lights, lighting, power accessories) reported on the early build years.; Engine and cooling-system complaints, including the available 4.6L Northstar V8 (oil leaks, cooling) and 3.6L V6 concerns on early cars.; Steering position/angle sensor failures cause rough or erratic steering feel and trigger traction-control, stability, and check-engine warnings; a recurring early first-generation complaint. | Full report ↗ |
| 2005 | Caution | 5 | Electrical gremlins across the body and accessory systems (warning lights, lighting, power accessories) reported on the early build years.; Engine and cooling-system complaints, including the available 4.6L Northstar V8 (oil leaks, cooling) and 3.6L V6 concerns on early cars.; Steering position/angle sensor failures cause rough or erratic steering feel and trigger traction-control, stability, and check-engine warnings; a recurring early first-generation complaint. | Full report ↗ |
| 2011 | Caution | 4 | Projector low-beam headlights dim badly over time from hazing and moisture intrusion, a GM-acknowledged fault that makes the car unsafe to drive at night until replaced.; Rear suspension toe-link recall: a toe link can loosen or separate and cause loss of vehicle control; recalled for inspection and replacement.; The 3.0L V6 (LF1) is prone to timing-chain stretch and wear (codes such as P0008/P0017, rattle on start, check-engine light); repair is labor-intensive and costly, and it is the defining mechanical weakness of these early second-generation cars. | Full report ↗ |
