Our company had purchased a 2008 Mack in 2009 and have had nothing but trouble since we purchased it.

The truck is currently in the shop due to fuel injector problems. Prior to this, October of this year, the mechanics claim they found debris and mold growing in the fuel lines. There had been a debate as to how frequently we changed our fuel filters and where we purchased our fuel. We keep maintenance records showing that we have replaced filter per specs. As far as the mold in the lines, that seems a little far fetched.

Beside the recalls we have had this truck in the shop five times. Fortunately the warranty is still in effect. In March 2010 there had been $1173.00 of work put into it for the cooling coil and injector cup kit. In June 2010 we had $6225.00 worth of work done on the rocker arms and camshaft. In July of 2010 another $551.00 for exhaust repairs.

I'd like to know if any other companies are having simalar problems.
