I strongly advise against taking any vehicle to North Mountain Auto. On 04/08/2026, I brought my…read more1996 Ford Probe GT to this shop for a water pump replacement. Dashcam footage explicitly shows the vehicle running perfectly fine that morning while it was at another shop receiving an estimate. It was dropped off at North Mountain Auto two hours later. On 04/13/2026, the vehicle was pulled into their bay exhibiting no problems, yet it exhibited severe running issues immediately after their "repair." The vehicle was subsequently removed to a neutral third-party shop via a recorded and documented chain of custody on 04/27/2026, ensuring no claims of tampering could be made. Independent diagnostics have since confirmed catastrophic engine failure, including air passing through the piston rings and a 25% leakage around the exhaust valve on Cylinder 5. Far more concerning than the mechanical destruction is the actively documented fraud and attempted cover-up. Forensic dashcam video and telemetry data captured the shop engaging in billing fraud by charging for one type of product (Asian vehicle blue coolant) while explicitly using another. Furthermore, on 04/20/2026, approximately an hour before I arrived to pick up the vehicle, the mechanic is recorded stating to the front desk that he had already lost two days the prior week and five hours that current day on the car and was "done." Twenty minutes later, footage shows them manually overriding factory settings via the base idle set screw (BISS) in a deliberate attempt to hide over 30 documented engine stalls and doctor the vehicle just enough to collect payment. This override occurred on four separate occasions. Additionally, the intake plenum was removed. There is absolutely no reason for its removal during a water pump replacement other than assessing internal damage; it provides no extra room or access and is 100% unnecessary. Both the mechanic and the shop stated they hadn't "worked in that area," claiming the damaged wires and broken clips had nothing to do with their work, which the visual evidence explicitly contradicts. When the shop realized my dashcams automatically trigger upon movement or when the key is turned, they attempted to format the memory cards twice while the car was sitting in their bay: once on April 15th, and again after hours following a "stealth" repair on 04/22/2026. This constitutes direct spoliation of evidence to cover up their actions. When I reached out via text message, they immediately denied warranty coverage, blamed the car, and then blamed me. However, until this week, they had no knowledge that the dashcam footage was NOT actually deleted. If you're going to perform such acts, you may want to research the specific dashcam to know how to format it. Just saying. I have retained a 236GB forensic data drive documenting every action taken in their bay. Now that every legal and regulatory action has been filed and is underway, I am leaving my experience here to help prevent others from suffering the same fate. Do not trust this shop with your property. Billed $2282.49 for them to destroy the drivetrain.

I love love love North Mountain auto!!! They fixed my ac a few days ago and I have told everyone…read moreI've talked to since how amazing this place is. They were mindful of the time I was working with to get it checked out (had to get my son from school that same day) and had it fixed in that time too. It cost the same for the fix as other places were charging just to diagnose the issue. I could tell immediately when I called that this was where I wanted to go because when I said the ac wasn't working, this was the first place to ask for context of what was going on. The other places I spoke to told me their (expensive) fee to diagnose. When I brought it in they offered a complimentary Lyft ride so I could wait at home. They texted me the repair details so I could approve it and then was able to come back just in time to get my son from school! I am so impressed at their kindness, honesty, process, and customer service! I rarely leave reviews but made a point to write this because they deserve it!

He had the car running in less than an hour, and traced the problem to a hidden wiring issue that I would have NEVER found. Rocky and his son Connor, are super nice and friendly, but also extremely competent mechanics. They aren't the cheapest around, but they are honest and fain in the pricing, and worth every dime. Their shop is small, but don't let that fool you - they are good! I will definitely recommend them to my friends and family, and will be back with any other issues I can't handle.

I brought my vehicle to Thunderbird Automotive Specialist with a fully functioning cruise control…read more It was working perfectly the day I dropped it off. When I picked up my car, the cruise control was no longer working. When I brought this to their attention, I was met with skepticism, as if my concern wasn't valid. That was frustrating, especially since I know my vehicle and how it was operating prior to service. They asked to keep the car for further inspection, which I agreed to. A couple of days later, they informed me the issue had been "fixed." However, when I asked what the problem was, I was told it was the cruise control switch. What raised serious concerns for me was what came next. When I asked for documentation or a repair record, I was told there was none--because the mechanic had paid for the part out of his own pocket. That explanation simply does not sit right. If a repair was performed, there should always be documentation--regardless of who paid for the part. Transparency is basic professionalism. The lack of paperwork, combined with the fact that the system was working before my visit, strongly suggests something happened while the vehicle was in their care. More disappointing than anything was that no one took responsibility, and no apology was offered. Mistakes can happen in any shop--but honesty and accountability matter. Because of this experience, I will not be returning.

They have serviced my car multiple times now and every time was day of drop off and pickup. They have had very helpful honest and transparent conversations about my vehicle and its issues. When my vehicle was at the end of its lifespan they even took the time to talk through other car models I could move on to. This business customer service mirrors that of a family. They care about their customers and won't lead you astray in any fix that isn't necessary. So now I'm taking my single recommendation and spreading it here. This is an auto shop you can trust and deserves your business.

I am extremely hesitant to bring my car to a mechanic shop normally because my dad typically fixes my cars for me. I wanted to give him a break so that is what lead me here. A little over a year ago I brought my car in for a horrible noise it was making. They diagnosed it and over $1,000 later I got the call my car was fixed and ready. As I was driving away, the same very glaring and obvious noise happened even before I left the parking lot. I called and let them know it was still making the noise so they had me bring it back the next day. I went on a drive with one of the mechanics so I could make sure they knew what noise I was talking about. They kept my car, put some oil/lubricant on a few things, and said good to go. Again, my car made the noise as I drove out of the parking lot. I called again to tell them it was still making the noise and I was told, "I don't know what to tell you, your car is old and we could spend years looking for what is causing the noise." And that was it. No offer to try to figure it out and I've now spent the money I barely could afford as a single mom and my car is not fixed. And I don't have the additional funds at the time to take it elsewhere because I spent it with them. Here I am, over a year later and the car is still making the noise because I'm nervous about trying at another mechanic. My friend over the past year has had two very similar experiences where the initial issue was not fixed at first and she has had to go back. She had to pay for the non-fixes and again for the going back to actually get it fixed. I have no doubt the work they did on my car was done properly, however it was not the right work or the fix for my issue. The employee even said he thought what they replaced looked like it had already been replaced before (like it was not the original part). I feel like that should have raised a flag that maybe it wasn't the part that needed replacing. I would use caution when considering going here.
