Horrible customer service and workmanship
Extremely disappointed with this shop. I paid over $2,500 for repairs and a full inspection to make my truck safe and road-ready, but after over three weeks, it came back in worse condition than when I brought it in. Communication was terrible — they never called or updated me unless I reached out, and the staff, especially the owner, were very rude. The oil was very low, some was still mixing into the coolant, the coolant was low and partially frozen, brake fluid was low and leaking from multiple areas, along with oil and other fluids, transmission issues I reported were dismissed, and there were many more leaks than before. I even took it back the same day shortly after I picked it up because of strange noises and drivability problems, and they told me it was fine and sent me on my way — clearly the work was not done properly. I left with more problems than I came in with and cannot recommend this shop.
