2004 Chevrolet Colorado 4dr Crew Cab Z71 LS 4WD SB (3.5L 5cyl 4A)
I had one of the cylinders worked on after 2 months and now after 2 and a half years need to have the entire cylinder head replaced - $4,000, of course out of warranty and with no help from GM. To be honest that's only the start of all the problems that I've had with the vehicle. The quality and reliability on this vehicle stinks along with GM customer service. I'll never by another GM.
Reliable vehicle. Replace the cheap plastic junk inside the vehicle.
