2022 GMC Sierra 1500 Maintenance Schedule & Costs

This 2022 GMC Sierra 1500 maintenance schedule is based on GM’s service guidance (oil life monitor + time/mileage items) plus common owner-reported service pricing from dealer invoices and independent shops. Notes that affect intervals and cost: - Oil Life Monitor (OLM): many owners see 5,000–7,500 miles between oil services in mixed driving; severe use often lands closer to 3,000–5,000 miles. - Severe duty (towing, frequent idling, dusty roads, short trips, off-road) typically means shorter fluid intervals and more frequent inspections. - Costs vary by region and engine (2.7T, 5.3, 6.2, 3.0 Duramax), but the ranges below reflect typical U.S. pricing reported by owners (dealer vs. independent). Estimated labor rate assumptions: - Independent shops commonly: $110–$170/hr - Dealers commonly: $160–$240/hr

Use this as a practical maintenance checklist. If your truck’s Driver Information Center calls for service sooner (OLM or warnings), follow that.

Practical strategies Sierra owners use to cut spend: - Bundle oil change + rotation + brake inspection at one visit to reduce labor add-ons. - Do cabin and engine air filters yourself (typical savings: $40–$120 per filter service). - If you tow or run larger tires, budget earlier for: - Transmission fluid (30k–45k) - Differential and transfer case fluid (30k–45k) - Use the Oil Life Monitor, but set a personal ceiling (many owners cap at ~7,500 miles). - Keep alignment in check to prevent $1,200–$1,800 tire bills earlier than expected.
