The service writers with the exception of "Tony" are arrogant and rude, "Chester", the worst. Mechanics that hold up the service writers seem untrained or don't care. Service 4WD light, going from 2 wheel drive to 4 wheel drive on the column, stayed in correct gear, but system telling me to service the 4WD. Mechanic told service writer he couldn't duplicated the error message that was coming on for months. The passive alarm system in the 2004 Chevy Tahoe z71 trucks have a well documented problem of something going a rye with the security system and the vehicle "thinking" its being stolen and won't start. There is a ritual required to reset the security system that will allow one to start the truck. The lock and key symbol appear on the dash at the same time the security problem begins. The mechanic first replaced the ignition switch, didn't correct the problem, then said couldn't duplicate the problem. The vehicle was in the garage at Page Chevy for three full days and all for the mechanics to do nothing, and the service writers to double talk, make comments, it was a bad experience and I tried this dealership for repairs more than five times. These repairs I'm told needed to be corrected by a Chevy dealer, the security system and 4WD, otherwise I would have never dreamed of taking the truck to a dealership, but this place is not a true dealership once you get to the repair shop. Never again.
