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.
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.

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.
GMT900 Sierra trucks are well known for failing door lock actuators, often starting with one door that unlocks weakly or only works intermittently before additional doors fail. Owners report the key fob cycling the locks while one or more doors remain stuck, requiring manual oper… Repairs typically run $180-$500. Severity: medium.
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.
Front wheel hub bearing assemblies on Sierra 1500 trucks commonly wear out, especially on 4WD models and trucks used with larger tires or in rough conditions. Owners report humming or growling that changes with speed, looseness in the front wheel, and in some cases ABS warnings o… Repairs typically run $300-$900. Severity: medium.
Sierra owners across both GMT800 and GMT900 generations frequently report small electric HVAC actuators stripping internal gears or losing calibration. The result is a repetitive clicking or tapping noise from the dash, air stuck on defrost or floor, or one side blowing hot while… Repairs typically run $150-$700. Severity: medium.
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.
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.
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.
Owners of 2007-2013 Sierra 1500 trucks commonly report the upper dash cracking near the passenger airbag area and around defrost vents, especially in hot climates. While primarily a cosmetic and rattling issue, some owners also complain that broken plastic edges and loose pieces… Repairs typically run $120-$1,200. Severity: low.
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.
