Build the inspection planTransmissionMedium
Torque-converter shudder.
- Typically appears
- 70,000+ miles
- What to inspect
- Test-drive at light throttle and feel for shudder.
HVACMedium
AC condenser failures.
- Typically appears
- 60,000+ miles
- What to inspect
- Confirm cold AC and ask about condenser replacement.
BrakesHigh
Hard brake pedal at low speeds and increased stopping distance due to engine-driven vacuum pump failure.
- Typically appears
- 40,000-80,000 miles
- What to inspect
- Start the engine, pump the brake pedal rapidly at idle. Check if the pedal goes rock hard or if the vacuum pump emits a loud ticking noise from the nearside front of the engine bay.
ChassisMedium
Premature surface corrosion on the ladder chassis due to the factory wax-based rustproofing peeling or washing away.
- Typically appears
- 30,000-60,000 miles
- What to inspect
- Kneel by the rear wheel arch and inspect the visible chassis rails. Scrape a fingernail along the black coating; if it flakes off in chunks revealing rust underneath, the wax has failed.
ElectricalMedium
Intermittent loss of power steering, flickering dash lights, and 'Service StabiliTrak' warnings caused by poor G218 earth connections.
- Typically appears
- 50,000-100,000 miles
- What to inspect
- Turn the steering wheel lock-to-lock whilst idling. Watch for dimming headlights, flickering instrument clusters, or warning chimes, which indicate high resistance in the primary earth circuits.
BodyLow
Water ingress causing damp carpets, a musty smell, and water stains on the rear headlining due to a degraded high-level brake light seal.
- Typically appears
- 40,000-70,000 miles
- What to inspect
- Open the rear doors and press your hand firmly into the rear corners of the headlining and the carpet beneath the rear bench to check for dampness.

Build my inspection planFrequently asked questions
Is the 5.3L Silverado reliable?
Broadly yes, but the AFM/DFM lifter issue can be expensive — inspect carefully and consider AFM-delete history.
What's the cracked dash issue?
Many trucks develop dashboard cracks with age and sun exposure; it's cosmetic but common.
Should I get the 6.2L?
The 6.2L V8 is powerful and well-regarded, though it also uses cylinder deactivation.
Why do customers complain about poor headlight visibility on early models?
The 2014 and 2015 models utilise a single halogen bulb behind a projector lens, resulting in exceptionally poor light output that struggles to illuminate unlit roads. General Motors issued a bulletin for voltage updates, but many owners resort to aftermarket HID or LED upgrades to achieve acceptable night-time visibility.
What does the 'Service 4WD' message indicate on the driver display?
This warning typically points to a failure within the transfer case encoder motor or its associated position sensor. It prevents the vehicle from shifting between two-wheel and four-wheel drive. A diagnostic scan is required to confirm, but replacing the encoder motor on the transfer case usually resolves the fault.
Are there specific gearbox fluid requirements for this generation?
Yes. The eight-speed automatic gearboxes are highly sensitive to fluid degradation. General Motors released an updated Mobil 1 synthetic LV ATF HP fluid to resolve shifting issues. When inspecting the service history, ensure this specific updated fluid was used during any gearbox oil changes to prevent future mechanical failures.
