I had an unfortunate experience during what should have been a basic oil change on my F-150. The…read moreservice included a brake inspection, and my wheels have security lugs. I was told I needed new rear brakes, so I planned to replace them myself on Saturday, 12/29/25. When I went to start the job, my security socket was nowhere to be found. So much for my Saturday project. The shop was closed for the weekend, so I couldn't resolve it. I met with the owner, Dan, on Monday. He ordered a new set of security lugs in hopes that the key would work. It did not. The tech had misplaced my original key during the brake inspection. Needless to say, it was a major inconvenience--and I didn't receive so much as an apology from the owner. This was my experience as a first-time customer. A $50-off coupon will not bring back my business.

Muffler Doctor & Auto Clinic in Cottage Grove was great. Needed muffler repair on one of our cars…read more Didn't want to spend much as this car bluebook value is really low (although any good running car is invaluable these days) Was pleasantly surprised by Muffler Doctor. I called, and they suggested I really had to come in, which makes sense. They gave me options/pricing, and really tried to keep the price low. The dealership quoted me $4,000 (to be clear, dealer did say 'shop around') to repair whole system. I drove out of Muffler Doctor with a repaired, safe, car for just under $200.

Ive brought every car I've owned to Muffler Doctor. Tires and brakes mainly, but it's always a…read moregreat friendly experience. No appointment needed, PLUS my car is always done the same day. Today I brought my Subaru in for brake pads and rotators... I thought easy fix. Well I was informed I needs calipers too. $900+ visit... after speaking with Tim, I remembered I had an extended warranty. After all was said and done, the Subaru dealership has to replace everything due to a manufacture issue. Tim was helpful through the whole process, and charged me NOTHING. When I asked if I could at least pay something for the diagnostics, he stated "oh no, I mean I would hope someone would do this for me in your situation." You do not find that kind of customer service anywhere now days. Most shops are all for themselves and how they can make money. It's great to know there are still good businesses and business people out there. Even the advisor at Subaru mentioned the guys at Muffler Doctor are good people. So if you're looking for a great place to bring your car... this is the place!

The last 2 times I called, they were able to get me immediately. Once for tires and once for a nail puncture repair. It bothers me to see a one star review. I know people usually do not leave reviews unless they are angry, so I am here to say I have never had nothing but EXCELLENT service at this Cottage Grove location. The managers name is Tony. I don't personally know him, but have remembered his name after the 3rd visit. He also seems to treat his workers well. Highly recommend for tires or tire service. I have never had any mechanical repairs there.

No biggie except I missed the call and picked up mid voicemail. So I called him back. I said just confirming the voicemail the manager legit said well didn't you listen to it. I said it broke up so I'm just confirming. He said yea that's what I said. Ok cool. My kid took the car in I had gotten a free oil change thing. Manager calls me. You never told me about this free oil change. I said I told the call center. He was so aggressive about it. My son said he was also rude to him in the store.
