Weird. To go weeks without seeing a diesel concern means one of two things to me:there's not a large quantity of tech comfortable with the Duramaxes either. GM sells diesels, but they've had a hard time getting dealers and techs to embrace. I'd wager the average dealer work on less than one real diesel concern per week. Many dealers in New Jersey can go weeks without seeing a diesel concern.
1. The engines are very reliable (NARRATOR: "They are not.")
2. The people who own them won't take them to the dealership for work.
Around me there are lots of businesses using Duramax pickups for real work. This includes the Chevy Kodiak (GMC Topkick) trucks that are HD above the 3500 pickups. When those businesses have a problem, it needs fixed NOW so they aren't losing money with a truck sidelined. I guess my Chevy dealership has a notable service department, but the service writers have given me the impression that their one or two diesel techs are usually booked solid with regular work and it's all on HD pickups. I can cruise through there and see any number of business trucks on the lot or in the service bays.
