The 2017 GMC Sierra 1500 belongs to the K2XX generation (2014-2018), built with 4.3L EcoTec3 V6 (LV3/LV1), 5.3L EcoTec3 V8 (L83, AFM), or 6.2L EcoTec3 V8 (L86, AFM) - 6L80/6L90 6-speed automatic, or 8L90 8-speed from MY2015 (6.2L) / MY2017 (select 5.3L). It takes dexos1 full synthetic - 0W-20 (5.3L/6.2L V8) or 5W-30 (4.3L V6). Oil changes run 7,500 miles typically, per the GM Oil Life Monitor. This is a late year of that generation, typically the most refined build after several years of running changes.
A 2017 GMC Sierra 1500 is 9 years old in 2026, which at an average 12,000 miles a year puts it around 108,000 miles - high mileage. Near 108,000 miles a vehicle is typically well into its second or third round of scheduled service, and unscheduled repairs start to outnumber routine maintenance. A written history is what tells you whether an item is due or already done. The next milestone on its own schedule is 120,000 miles, about a year away at average use - a repeat of the 30,000-mile service.
The fault most worth knowing about on this generation is 8L90 shudder at light throttle on 6.2L and later 5.3L 8-speed trucks - a full DEXRON-VI exchange resolves most cases. Owners also report AFM lifter failure on the 5.3L L83 and 6.2L L86 - collapsed lifters cause a cylinder misfire and audible tick; and Cracked dashboard and AC condenser leaks are common cosmetic/reliability complaints across 2014-2018 GM full-size trucks. 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.
