I took my truck here after my disillusionment w/Firestone diesel techs, that failed to fix my truck issues. I've read some negative reviews on this place below. What I can say is I have first-hand knowledge of this firm "actively" taking action to correct perceived or real quality problems and (a typical car repair shop issue of) "over promising". For folks that want "same day dry cleaning", this is not the shop for you. These people actually still diagnose highly technical rolling computers w/diesel engines, and that takes both time and experience; both of which this shop manages well, if you don't want some dealership just going down a parts-swap list until they get to the actual problem on your vehicle. The short answer is, as a new customer, I could see they are fixing their business gaps in customer service, and working to improve communication coming in the door, as well as going out the door. And in the time I've worked w/them recently, they have taken a number of tangible actions to improve their customer service, quality of repairs, and "doing the right thing by the customer". So, I had a particularly challenging turbo issue w/my 2003 Ford F-250 6.0L diesel. MD Auto & Truck Repair went "above and beyond" to diagnose the problem and fix it completely. This was an issue that did NOT throw a diagnostic code, but resulted in poor running of the engine, backblow, and loss of power. I also had a brake line replaced, while the vehicle was in the shop. Overall, I am extremely satisfied with the repairs and the truck is running great again. The bill was both affordable and fair so overall, I can't say anything negative about these folks. They strive to be professionals in a world when accountability is usually a distant afterthought. I would absolutely use them again; especially for diesel repairs. I was expecting $3-4K in injector replacement. In the end, we didn't have to touch the injectors at all. That's a worth note, since turbo issues were causing (rotating) injector codes. A lessor shop would have changed out injectors, which would not have fixed the issue. I look forward to working w/them again.
