The 2022 GMC Sierra 1500 belongs to the T1 generation (2022-2026 refresh) (2022-present), built with 2.7L TurboMax I4 (L3B, rebranded), 5.3L EcoTec3 V8 (L84 only, DFM), 6.2L EcoTec3 V8 (L87, DFM), or the 3.0L Duramax I6 diesel (LM2 in MY2022, updated to LZ0 from MY2023) - the 4.3L V6 and base 5.3L L82 are dropped. It takes dexos1 full synthetic - 0W-20 (5.3L/6.2L V8) or 5W-30 (2.7L TurboMax); dexosD for the 3.0L Duramax. Oil changes run 7,500 miles typically, per the GM Oil Life Monitor. This is the first model year of that generation, so it is the build most likely to carry early-production quirks and the most likely to have accumulated technical service bulletins.
A 2022 GMC Sierra 1500 is 4 years old in 2026, which at an average 12,000 miles a year puts it around 48,000 miles - early ownership. Around 48,000 miles a vehicle is typically past its earliest wear items and into its first real round of scheduled service. Costs are still low at this stage, which makes it the cheapest point to stay ahead of whatever this vehicle's own schedule calls for rather than catch up on it later. The next milestone on its own schedule is 60,000 miles, about a year away at average use, listed as: Replace spark plugs and inspect spark plug wires and/or boots - 2.7L L4 Turbo only.
The fault most worth knowing about on this generation is DFM lifter wear on the 5.3L L84 and 6.2L L87. Owners also report First-model-year risk on the updated LZ0 diesel tune (MY2023) - fewer years of fleet data than the outgoing LM2; and Electric park brake actuator squeak or failure to release on the rear axle at higher mileage, carried over from the 2019-2021 powertrain era. None of these are certainties on any individual vehicle - they are the patterns worth checking for when you buy or when a symptom appears.

Maintenance keeps these away, but when the dash does light up these are the codes this vehicle throws most often - each with what it means and what the repair actually costs.
