Moved to Worcester a year ago and quickly became a repeat customer with my 2005 RAM 2500 turbo diesel truck. After several communication challenges with service reps, I began working exclusively with Mark, the service manager.
Everytime I'd bring my truck in, they would have a list of unrelated things they claimed needed to be fixed. In the beginning, I just went with it and followed their recommendations, but over time, I began to question whether these parts really needed to be replaced. The last straw occurred when I had my truck towed to their shop after it suddenly began running very rough on the highway and had no power to the point it was about to stall. They called me the next day and gave me a list of trouble codes being thrown and quoted me $10,000 for new fuel injectors, common rail, fuel lines, fan clutch, etc, etc, etc. I asked them how much they'd give me on a trade-in, and after waiting 3 days for a reply, they said $2000 (still owed $10k).
Being concerned they were rip off artists, I decided to call around and ended up speaking with the owner of Massdiesel Performance in Bellingham. The conversation went so well I had the truck towed to their shop the following day. They called me a couple hours later and asked who told me the truck was throwing all those codes and needed all that work done - because they couldn't find any of those codes in the history nor did they think it needed any injectors. They said they thought the issue was a blown head gasket. They also said they drove the truck around for 20 minutes, and other than a very small water leak, it was running just fine (no water in the oil, no overheating, plenty of power, etc). They also said I could probably get by without having it repaired for a couple more months - just keep an eye on the water and oil.
After mulling it over, I decided to trade the truck in, so I picked it up the following day, and guess what - THEY DIDN'T CHARGE ME A SINGLE PENNY! I drove the truck like that for another 2 months while I worked with another Dodge dealer to custom order a brand new 2016 RAM 3500 turbo diesel and got $17,000 on my 2005 trade-in.
After all of this, I called and spoke with the GM of Harr, who backed all of his cronies and said they did everything right. I finally ended the conversation telling he and Mark that I'd never be back and I'd be sure to leave feedback on the internet about my experience, so here it is . .. The guys at Harr are happy to rip you off if you let them. AVOID THEM AT ALL COSTS!
