Cummins Sales and Service 914 Cromwell Avenue, Rocky Hill, CT 06067

"This shop has been awesome!!! My truck was in the shop immediately and diagnosed within a day. Dawn up front was very helpful in getting me setup with a hotel and getting the truck in asap. Dana was my advisor that kept in contact with me every step of the way and she was on point. I can’t say enough about the team at Cummins in Rocky Hill, CT. Thank You!!"

"I cannot say enough good stuff about bringing my Cummins powered RV to this dealer when hitting some gigantic pot holes on I95 in NY. I had a clamp break causing a charge air hose to partially fail. I was on a long trip over 1300 miles from home. They knowing I was far from home took it in right away, found the problem. Best of all had parts in stock! That is huge! Fixed my 6.7 and I was back on the road by 3pm. Anyone that owns an RV will understand what a big deal getting fixed and back on the road is. I would give them 6 stars if I could."

"March of this year we brought our Peterbilt 386 to the Rocky Hill, CT location for a ticking noise coming from the engine when RPMS go up. The technician found excessive back lash on the gear train. The estimate to reset timing of gear was $1,779.50, which we agreed to. During the repair they found progressive damage in the fuel pump idler gear and camshaft idler gear both having excessive play. The estimate for repair was $4,904.67, which we agreed to. The technician then found issues with the gear housing and provided us with two more estimates, one to replace the gear housing for $15,567.86 and one to add the gear housing repairs for $14,917.90. At that time, they had no stock on the gear housing and their factory would need to source this part to try and locate one. They had no estimated time of arrival for the gear housing. Since they did not have any estimated time for the gear housing part and we could not have our truck in the shop for an unknown amount of time, we chose the repair option. Throughout this entire process we were told the warranty for all work was for one year. Now lets fast forward. Last week my husband notice oil leaking from the gear housing. I reached out to Dana at Rocky Hill, CT and explained to her we just had this repaired in March and its leaking. She replied if it’s something we repaired then it would be covered under warranty. This location did not have an opening for diagnostics for two weeks so she said we could take it to any Cummins or Peterbilt dealer and give them the paperwork (which she provided me again by email). We took our truck to Peterbilt in Florence, SC (who are AMAZING) and they found the gear housing was leaking from were Cummins “repaired” the gear housing. There was no sealant when they opened the cover nor on the screws that Cummins replaced. Peterbilt reached out to Cummins in Rocky Hill, CT since it is under warranty and they refused to cover the repair, stating this was not covered under warranty because we chose to “repair” in March and not “replace” the gear housing. Also, I reviewed all my paperwork and not anywhere did it say that or that it was a temporary fix and let’s make something very clear we wanted to replace the gear housing however Dana did not have an estimated time frame for getting the part. We were already spending $15K, another $1K did not matter at this point. We contacted the Area General Manager, Guy W. Reid and he said NO. We even offered to pay for the part which is roughly $700 and for some of the labor, if they could help us with the remaining labor costs and they still said NO. Was I asking for too much to have them cover only a portion of the labor costs? I sit here and wonder is there no loyalty to customers anymore? $15K was a lot of money for us but we wanted our truck fix correctly, so we agreed to each estimated amount they gave us. Look where that got us. We are a one truck business, and we are now left to pay out of pocket roughly $3K. These big companies seem to only want to take money from hard working people who are just trying to make a living for their families."

"I cannot say enough great things about the Cummins service center in Rocky Hill CT. Everyone there was accommodating, friendly, knowledgeable & took the time to explain & document everything. We called them around closing time & they stayed on the phone to diagnose the issue & squeezed us in at 9 am the next morning. By 2pm we were back on the road issue resolved. Thank you to Dino, Steve & the entire staff. Every step of the way Dino kept us informed & always ended the update with is there anything else I can do for you. I highly recommend them for your service issues or regular maintenance."

"I had wasted 21 hours between the dealer and Travel America repair shops before arriving at Cummins Coach Care at Rocky Hill CT. Dino patiently took notes and inspected the rig. Within 2 hours, they made a hole in the repair line and brought the rig inside for inspection. There was no fault codes just a small leak but the entire rear of the rig and toad were covered in oil. Kevin was the technician who worked late to help get us back on the road. Dino and Kevin always kept us informed of their progress and findings. No surprises. In the end, it was a simple overfill during its last oil change. Extremely pleased with their level of customer care, professionalism, and technical knowledge. Love these guys! And, by the way, the Italian restaurant Case Mia around the corner was also a great find! Good Italian food while the rig was being repaired...best of 2 world!"
