Chevrolet Silverado 1500 2014–2018 · Pre-purchase checklist

Bring this to the inspection. Every check below is specific to this generation's documented failure modes — not generic used-car advice.

1. Check 01

   Cold-start the 5.3 and listen for a ticking/tapping that doesn't clear — a classic collapsed-AFM-lifter tell. A misfire code (P0300-series) on one of the deactivating cylinders is another.

2. Check 02

   Check oil level and ask for oil-consumption history. GM's own 'acceptable' rate is up to 1 qt per 2,000 miles; faster than that on a 5.3 is a red flag.

3. Check 03

   On 2015+ trucks with the 8-speed, drive at low speed (15–25 mph, light throttle) and feel for a shudder/vibration like driving over rumble strips. Confirm whether the corrected transmission fluid flush was done.

4. Check 04

   Run the A/C on a hot day until fully cold. The condenser and the high-side hose are known to leak; warm or intermittent A/C means money.

5. Check 05

   Inspect the dashboard top for cracks, especially around the airbag seams and center vents — a widespread cosmetic-but-pricey complaint on these trucks.

6. Check 06

   Verify the 2014 electric power-steering recall (sudden loss/return of assist) was completed — a dealer can confirm by VIN.

7. Check 07

   Scan for stored misfire, lifter, and transmission codes even if no light is on; check for a wiped camshaft if lifter noise is present.
