How to buy a reliable used 2020 Silverado 1500 (inspection checklist)
Before you buy:
- Run the VIN for open recalls and confirm completion.
- Ask for proof of:
- Oil changes (ideally every 5,000–7,500 miles; shorter for severe use)
- Transmission service history if used for towing (around 45,000–60,000 miles is a common real-world interval)
- Any infotainment or powertrain software updates
Test drive checks (15–20 minutes, mixed roads):
- Cold start: listen for abnormal ticking that persists after warm-up.
- Transmission: feel for shudder at light throttle 30–60 mph; check for harsh downshifts.
- Electronics: test camera, parking sensors, Bluetooth, CarPlay/Android Auto, and all USB ports.
- 4WD: engage 4HI/4LO (where equipped) and confirm smooth engagement.
Ownership planning:
- If buying an 8-speed truck, consider budgeting for a fluid service and software check soon after purchase ($300–$550) unless documented.
- If you rely on infotainment daily, verify everything works perfectly—module repairs can be expensive out-of-warranty.
