I have had our family vehicles in a variety of maintenance facilities, many of them owned by immense business enterprises paying profits to shareholders. Our vehicles, on several occasions, had totally rookie maintenance mistakes, misorders, mis-assemblies, plain old misses. Finding the Alauria family repair shop, the "Servants of Sunnyslope Rising" , quality repairs, three year, 36,000 mile warranties, made us permanent customers. Three more family vehicles get serviced here now. Proper inspectiond and troubleshooting, no rookie mistakes. Follow up as needed, Pricing appropriate for this level of service. And my life savings are not getting paid out to a global shareholder pool.

However, in an emergency where my truck broke down and I needed it fixed ASAP, he had me tow it over the same day and had it completely fixed just a day or two later.

Biggest mistake in my life bringing my truck in here to get worked on. They're incompetent. I've…read moretaken my vehicle back several times for the same issues. Each time they tell me it's ready and everything is good, there is either the same issues or new ones. They replaced my original motor and trans with a larger, supposedly newer one. But never changed anything to accommodate the extra power. I finally sent them a certified letter threatening a lawyer and they finally put in the proper cooling system to accommodate the bigger motor and said everything was good to go, yet again. Unfortunately, when they installed a new temperature gauge, they screwed up something with the electrical because now, when I put the lights on, I have no right side turn signal or brake light and my windshield wipers no longer work. My original antenna is missing, speedometer is still messed up, there's oil on top of this supposed "new" motor, you can smell gas leaking somewhere......before this final time I brought the truck in, I called and got a voicemail for the manager's real estate business! I also asked if the can increase the differential gears to accommodate the newer larger motor and trans and was told they don't have anyone there that can do that. WTF? After almost $30,000 dollars given to them, I not only have a vehicle that isn't legal to drive, but I have to take it to a REAL mechanic to fix everything proper. Can't wait to read their b.s. response to this.

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!

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.
