My 05 AV was born in 4/05. I purchased in 5/05 with 3 miles on the clock. Since then:
Hydroboost replaced (and still kicking back)
Power Steering Pump whines like a cow in a blender
Tranny shifts like a flake (cured by new code)
All bed covers replaced for warpage (and waiting on yet another one for fitment)
All rail gaskets replaced (and still leaking)
Still waiting on midgate and crossbar seal for replacement.
4WD whines intermittently
A/C compressor sometimes bangs loudly when engaged
Third Brake Light not working (loose harness in roof)
Interior alert bell quit working completely...then started working again.
After that, the seatbelt warning quit working
Sqeaks, creeks, thuds and rattles aboud from front end (and behind gauge cluster) with VERY light off-roading (like a dirt road with a few dips and bumps).
I honestly believe that the AV is a very cool truck with many solid features. But after this, I'm not sure I could trust owning another. That's really hard for me, as a die-hard GM fan, to say. At this point, every new noise I hear has me wondering what's going to break next!
To be fair, the dealer - Casa Chevrolet in Albuquerque, NM, has been fantastic thus far. The service manager is currently pushing GM to assist them in a buy-back/trade-out. I really wish I could get my 98 GMC Sierra back. We may just wind up in a deck out Tahoe.
So, no offense intended toward those who love your AV's. But this one's been painful enough in such a short time, I'm just not feeling quite as much love. I'll post a follow up with whatever happens.
All the best!
