At 5000 miles, I have had the following:
- Front left axle/shock squeak right off the showroom floor (& they would not fix it the day I bought it). Had to bring it back to repair.
- Bad rear passenger window lever (would not close all of the way). They replaced entire window.
- Transmission downshifts to 1st too soon on some occassions on hard acceleration and fails to shift from 3rd to 2nd around town when I need the extra torque. Maybe PCMs for less program can alleviate.
- Loud popping exhaust sections on cool-down.
- Some uneven lines in body panels.
- Unexpected surface rust/corrosion on driveline and some suspension hardware (don't they paint anything anymore?)
- 13 mpg city, 17 mpg highway at 70mph, 15.5 mpg at 80 mph.
- I just hope the common 1996 Impala SS problem of shorting kapton insulated wires in the gas tank does not happen on the Silverado!
