Karns automotive is a trustworthy, fair, wonderful repair garage. Beth greets you, and is so kind, helpful, and amazing! And she does Everything except the actual repairs!!! : ) Jeff is so kind. He is the manager and is the one who took care of my car both times I have come to the shop. My car is very old with tons of miles. Jeff is so knowledgeable, and he is brilliant & creative and helps to do repairs in the most affordable way. It can be very easy to feel taken advantage of at car repair places, but here at Karns automotive in Groton you know you are being taken care of by the best! AND the respect and kindness along with my better running car are things I am incredibly grateful for. : ) Thank you Karns Automotive for being a gem! : )

I've been going to this garage for over 15 years. They are very honest, super helpful and honestly the nicest people. Jeff is a great guy and Beth who runs the desk is really nice. I definitely recommend them. And they always work to give the most fair pricing.

Very honest, very good prices. They took care of me on short notice when other shops tried to take advantage of my situation. Highly recommended.

I can't say enough good things about this place. I recently received very poor service from two other local auto shops. I was given very poor service and it was very expensive and they still didn't fix my problem. I brought my car in to Karn's on a Tuesday morning with the idea I would not even be able to afford to fix the problem. Well not only did they fix the problem they went above and beyond to chase down a part and get the car back to me in 24 hours and the price was unbeatable. Thank you,Thank you! You have a customer for life!

Seriously, take your car here. This is the honest car shop that you hope to find in every city that you live in. They replaced my sway bar linkages and cleaned out my drains that were causing water to build up under the spare tire area all for about half of what Firestone quoted me for. They were extremely busy and short-staffed so I had to come back for them to clean out my drains. They ended up doing it for free which was super nice. They are also just generally nice people unlike what you find at some car shops. Just generally happy, not condescending and genuinely open to explaining issues to you. You can rest assured that they are not trying to rip you off which is much more than you can say for most car shops. Will definitely be coming here anytime I need car service.

Highly recommended by a coworker. My 20 year old SUV needed multiple seals and gaskets. Estimate was right on the money. Great communication with Beth. Very happy that my SUV is purring again! Oh, and they DON'T try to upsell you on "additional" work! Excellent place!

Top notch service. Staff are great! Jeff (the owner) always greets my with a smile and a hand shake. Beth is the BEST with scheduling appointments, and greeting customers. Both mechanics take their time on all vehicles being serviced.

Definitely the best experience with a mechanic I have ever had! I dropped my VW Jetta off with an issue with the turbo. I thought it would be a simple fix due to a boost leak. This was not the case. Instead a rod within the turbo had broke. There are no replacement options currently being sold for the rod and due to the location of the rod the fix is extremely hard. Any other mechanic would have told me that my only option is to have a whole new turbo put in the car which would cost around 2 grand. Not only did these guys spend countless hours trying to find the rod replacement, but also somehow found a way to fix the rod without replacing the turbo. Amazing, they saved me over 1500 dollars! I am not from this area and I have tried many mechanics to work on my Jetta over the years and these guys are definitely the best I have found in New England. Could not recommend more!!

This place is trash. They charge you for work that isn’t done, they rush through work leaving things unfinished. Don’t recommend this place at all. I went here almost 3 years ago approximately when I was stationed in Connecticut. I took my 2004 Toyota Camry for a Tune up. I wanted the spark and valve cover gaskets replaced. Years later I come to find out that the valve cover bolts were loose this whole time. He said he changed the transmission fluid on 04 Camry and I believe he lied about that too but he still charged me for it. He also replaced a bad motor mount on my car near the radiator but didn’t check to see if the other motor mounts were bad. The radiator job came out fine no issues there. The only reason I’m putting this review up now is because in doing a lot of work on my car years later to only find the little things that he did weren’t good. I think the people that give them good reviews don’t actually check the work that they do under the hood.

While vacationing in Connecticut a section of my exhaust system became disconnected. The woman at the office area was outstanding. She went over and above to get my cars exhaust repaired. She prioritized the inspection and repair of my vehicle in order to help my wife and I get back on the road and continue our vacation plans. I wish I remembered her name so I could post it here so her coworkers would know who I am referring too. If we are ever back in the area again I would be sure to drop in to thank her again personally. Thank you ever so much!! Brian & Bonnie Litwin

As a business owner running multiple companies for many years, I understand how important customer satisfaction and real reviews are. That’s why I’m very honest when I recommend a place. I’ve known this shop for over 12 years. Between myself, my friends, and my family, we’ve had more than 10 vehicles serviced here. Every single time, the experience has been professional and consistent. The owner is knowledgeable, experienced, and truly cares about his work. His team is solid—from the front desk, who handles calls and customers with professionalism, to the crew in the back doing quality mechanical work. And the best part? The owner personally checks the final result. That says a lot. He recently worked on my BMW i8. For those who know, it’s a hybrid with a 3-cylinder engine. Most people would say you can’t get a real muffler sound out of that car. He made it happen. What seemed impossible became possible. That level of skill and commitment is rare. A million thanks to the entire team. If you believe in supporting local businesses that actually care about quality, this is the place. Thnx again Jef 🏆🏆🏆🙏

We had the best experience with Karns Automotive! My 19 year old Saab had a sudden coolant leak and the engine was smoking. I thought the life of the car was over. Within a few hours, they diagnosed the issue, found the rare part it needed, fixed it and I was on my way. I couldn't have asked for a more trustworthy, reliable and knowledgable automotive shop! I can't recommend them enough!

I cannot thank the kindness and generosity of the hard workers at Karns Automotive Center enough. We had bought a very used car for my college age son down in Florida, that needed several fixes before we drove down to him. A week before we were (unchangeably) scheduled to depart for a major road trip, the steering wheel started vibrating at high speeds, and an alignment was not the easy answer. Karns spent 3 days diagnosing it. When they fixed one thing, it would correct some of the problem, but not all of the way, so they kept on going. I know they ended up replacing and fixing multiple things, and then they way... WAY, UNDER charged me for it all. I was floored. It brought tears to my eyes. They knew that I had that long road rip ahead of me, and they were all working on trying to figure out all of the problems that were causing the shaking in the wheel (there were like 3 or 4 individual things!). They didn't want to give the car back until it was safe for that long trip. That is the kind of care and quality that I want in an auto mechanic team. They clearly lost profit on the time spent solving the enigma that was my car, but they chose to not give up, and to not punish me for it. They made me feel safe on my trip down to Florida. I would recommend Karns Automotive center every time!!

I have been going to Karns for the past 10 years and realized I’ve never left a review. Karns is the only mechanic I will ever use, Jeff and the employees are so thorough, knowledgeable and informative for whatever is going on mechanically with your car. They explain in detail what is going to be fixed, the problem with it, and always look for the best deals for parts. The front desk lady is also very knowledgeable and explains everything you need to know perfectly. They truly are a business that will help you out when needed!

Unusual problem with the speed sensor and hub. They were able to diagnose multiple problems and repair them all in a very short time. Workmanship was excellent. Personnel are easy and pleasant to talk with. I do and have highly recommend(ed) Karns to everyone.
