2008 GMC Sierra 1500 SLE2 4dr Crew Cab 4WD 5.8 ft. SB (5.3L 8cyl 4A)


Just after the power train warranty expires my AFM lifter sticks.
$3000 shop bill later and some internet research I know to watch my oil level like a hawk and never purchase another GM.

Also the Massive cracks in my dash remind me of 80's GM.
Its nice to see them bringing back the materials from their 80's cars.

Don't buy one of these trucks.
Buy new and dump them when out of warranty.

Best Features

I would say the drain your wallet feature is my favorite. Knowing that GM is pushing AFM on all their trucks makes my decision to avoid future Government Motors vehicles an easy one.

Worst Features

Fix or Lose the AFM system. Roll out a small diesel in 1/2 ton trucks. Do a proper re-call for older AFM trucks and restore belief in your product.
