Question 1

Cracked dashboard (Silverado 1500 GMT900)

Accepted Answer

The dashboard on the Silverado 1500 GMT900 commonly cracks, especially on trucks parked in the sun, usually starting near the defroster vents or passenger airbag. It is cosmetic but can be expensive to replace.

Question 2

4L60-E automatic transmission failure

Accepted Answer

The 4-speed automatic on these trucks is known for 3-4 clutch pack failures and broken sun shells, causing slipping, loss of 3rd/4th gear or reverse, especially when towing. Usually appears after 100,000 miles (160,000 km).

Question 3

Excessive oil consumption on the 5.3 V8 (2007-2013)

Accepted Answer

Gen IV 5.3 V8s are known for burning oil through stuck piston rings, made worse by the AFM system venting oil vapor into the intake. Symptoms include a dropping oil level, fouled spark plugs (often cylinders 1 and 7) and misfires. GM issued TSBs with piston/ring replacement and an AFM oil deflector.

Question 4

Active Fuel Management lifter failure (5.3 V8)

Accepted Answer

GM cylinder deactivation (AFM, later DFM) uses collapsible lifters that can stick or collapse, causing a ticking noise, misfire, a check engine light (P0300 series) and possibly a bent pushrod or damaged camshaft. Common on 2007-2013 5.3 V8s and again on 2019-2022 5.3 V8s.
