My wife was driving the Duramax today and the temp had dropped to -10, after about 30mins it started to gel. She made it to work in Elburn safely. I called the service department to see if they could replace the fuel filter when she got off work at 330pm, was told yes and I gave them my name. My wife shows up at 330pm and no I ne wanted to help her. Finally when 1 of the mechanics realized she was standing right in front of them they agreed. Charged my wife $155.00 to change a Fuel Filter on a Duramax, for a 10 minute job. I wouldn't advice anyone to go here for work.
