What owners say across generations

Sentiment is mixed and heavily dependent on model year and powertrain. For older models (circa 2000-2019) equipped with the 6.0L gasoline V8 and corresponding transmissions (e.g., 6L90), owner feedback is overwhelmingly positive regarding long-term reliability

  • Transmission Valve Body Failure (10-speed Allison, gas models) — Causes the truck to buck, enter limp mode, fail to shift, and become undriveable. Part is on national backorder, leading to repair delays of weeks or months. Primarily affects 2024-2025 models. Frequency: very frequent.
  • Engine/ECM Software Issues (6.6L Duramax L5P Diesel) — Multiple reports of check engine lights, reduced power, limp mode, and error codes (e.g., P060C, P133B, P133D) related to software anomalies. A specific service bulletin (PIP6066A) acknowledges the problem with no immediate fix, eroding owner trust. Frequency: very frequent.
  • CP4 High-Pressure Fuel Pump Failure (Duramax Diesel) — Known failure point that can destroy all eight fuel injectors with metal debris. Mitigated by using fuel with higher biodiesel content or aftermarket lubricity additives. Frequency: recurrent (discussed as a known risk).
  • Electrical & Infotainment Gremlins — Range from complete battery/charging system failures (2016 model) and dashboard/infotainment blackouts/resets (2015 model) to Bluetooth/Android Auto connectivity dropouts (2025 model). Often difficult to diagnose, pointing to wiring harness or module issues. Frequency: recurrent.
  • Four-Wheel Drive System Failures — Multiple reports across older generations (2001, 2003) of 4WD failing to engage, linked to faulty actuators, encoder motors, or transfer case issues. Frequency: recurrent.
