What is the 2014-2023 GMC Sierra 1500 Electronic Brake Control Module Failure?

The electronic brake control module (EBCM) experiences failures causing ABS, traction control, and stability control systems to malfunction. Issues range from warning lights illuminating to complete system failures. The 2023 models have a specific recall for software that may fai… Repairs typically run $150-$1,500. Severity: high.

What is the 2007-2021 GMC Sierra 1500 P0016 — Crank/Cam Correlation Fault from Stretched Timing Chain on 5.3L AFM V8?

P0016 means the crankshaft and Bank 1 intake camshaft are out of sync beyond tolerance. On the 5.3L V8 Sierra 1500 this is a signature failure because of two engine-specific problems: (1) the timing chain stretches over time — accelerated by AFM lifter debris and extended oil-cha… Repairs typically run $150-$1,800. Severity: high.

What is the 2007-2018 GMC Sierra 1500 P0700 — Transmission Fault Flag from Failing 6L80/6L90 Internal TEHCM?

P0700 itself is only a flag: the Transmission Control Module has stored one or more transmission faults and is requesting the MIL. On Sierra 1500s with the 6L80 (and 6L90 on heavier variants) 6-speed automatic, the notable design issue is that the TCM is integrated into the valve… Repairs typically run $600-$2,500. Severity: high.

What is the 2014-2018 GMC Sierra 1500 Intermediate Steering Shaft Clunk?

The upper intermediate steering shaft develops excessive wear causing a pronounced clunking noise when turning the steering wheel or going over bumps. The issue is caused by wear in the shaft's universal joints or the plastic bushing near the firewall. GM has redesigned the part… Repairs typically run $50-$600. Severity: medium.

What is the 2014-2020 GMC Sierra 1500 A/C Compressor and Clutch Failure?

The A/C compressor is prone to premature failure due to faulty welds, insufficient lubrication, or internal mechanical failure. When the compressor fails catastrophically, metal debris contaminates the entire A/C system requiring replacement of multiple components. The A/C clutch… Repairs typically run $500-$2,500. Severity: medium.

What is the 2014-2023 GMC Sierra 1500 Direct Injection Carbon Buildup on Intake Valves?

Direct injection engines do not spray fuel over the intake valves like port injection systems, allowing carbon deposits from oil and blow-by gases via the PCV system to accumulate on intake valve backs and ports. Over time, this buildup restricts airflow causing performance and e… Repairs typically run $400-$800. Severity: medium.

What is the 2007-2018 GMC Sierra 1500 P0430 — Catalyst Efficiency Bank 2 (Driver-Side) Converter Failure on 5.3L V8?

P0430 is the Bank 2 counterpart to P0420 and, on the Sierra 1500 V8, points to the driver-side (Bank 2) catalytic converter falling below efficiency threshold. The mechanism is identical to Bank 1: the rear O2 sensor voltage begins mirroring the front sensor, so the ECM concludes… Repairs typically run $400-$1,500. Severity: medium.

What is the 2007-2017 GMC Sierra 1500 P0420 — Catalyst Efficiency Bank 1 from Failing Cat, Often Caused by AFM Oil Consumption or Air-Box Debris?

On the 5.3L V8 Sierra 1500, P0420 sets when the downstream (post-cat) O2 sensor tracks the upstream sensor too closely, meaning the Bank 1 catalytic converter is no longer scrubbing exhaust efficiently. The distinctive part on these trucks: the converter frequently dies premature… Repairs typically run $400-$1,500. Severity: medium.

What is the 2007-2022 GMC Sierra 1500 P0011 — Intake Cam Over-Advanced from Sludge-Clogged VVT Solenoid on 5.3L V8?

P0011 means the Bank 1 intake camshaft is timed more advanced than the ECM commanded — the phaser is stuck/biased advanced. On the Sierra 1500 5.3L/6.2L, the dominant cause is a VVT (camshaft actuator) solenoid whose internal screen has clogged with oil sludge or AFM debris, jamm… Repairs typically run $40-$450. Severity: medium.

What is the 2007-2019 GMC Sierra 1500 P0128 — Engine Never Reaches Operating Temp from a Stuck-Open Thermostat?

On the Sierra 1500, P0128 means the coolant did not reach the expected regulating temperature within the time/airflow the ECM predicted — almost always a thermostat stuck open (or partly open) so the engine runs too cool. The GM thermostat on the 5.3L/6.2L is integrated into a pl… Repairs typically run $200-$850. Severity: low.

What is the 2007-2023 GMC Sierra 1500 P0455 — Gross EVAP Leak from Failed Vent Solenoid, Missing Gas Cap, or Broken Vent Hose?

P0455 indicates a large (gross) EVAP leak — the ECM cannot pull or hold vacuum in the evaporative system at all. On the Sierra 1500 the classic causes are a completely missing/unsealed gas cap, a stuck-open or failed EVAP vent solenoid (mounted under the truck near the fuel tank/… Repairs typically run $20-$350. Severity: low.

What is the 2007-2018 GMC Sierra 1500 P0442 — Small EVAP Leak from Loose/Cracked Gas Cap or Fractured Filler Vent Hose?

P0442 on the Sierra 1500 is a small EVAP leak detected during the ECM's key-off/idle vacuum test. On these trucks the two most common real-world causes are a loose, worn, or cracked gas cap seal (the cheapest fix and always the first check) and — a documented GM issue (TSB 15-NA-… Repairs typically run $20-$250. Severity: low.
