Raul was called as one of the businesses to discuss rebuilding a 283 CI V8 in a 69 C Chevy…read more In picking up the vehicle, after Raul told me it was ready. I only made it out of town 20 miles and it quit running, so I pulled over, stopped, and towed it home. This started an expensive fix in which Raul stated my warranty was in place but he wouldn't cover the problem that came up. The problem was that the number two exhaust rocker stud pulled out enough to have the rocker move aside. In summary I found that the number 6 spark plug was not tightened in place. Also the intake bolts which were to discussed to move to all number M8, I found that the intakes had 11 M8, and one M10. I found that one of the holes between number 3 and 5 was drilled in error, and a M10 put in place, because the ship and sailed for a M8 and now an M10 to fix the error. Raul converted to me that all I intake bolts were M8 size and never made mention of this mistake that would cause all the holes to go to M10. What Raul refused to do was fix the head because of the rocker stud pulling out so I in turn with a disability severe pain and the difficulty to even get up in the morning was now my responsibility to try and do this myself because I have limited funds and saved for years to get this done. I had to service each boss, and drill and pin all of them to avoid future breakdowns. I was able to pound the number two exhaust rocker stud back into the boss, and drill and pin that as well. When I picked up the truck, I found it odd to have one intake bolt an Allen bolt,and all the other intake bolts, standard socket head. After taking the intake off, the aforementioned, I found that I had M8 on all intake bolt holes, but one of them for the number four cylinder that was loose, and another was an M10, aforementioned between 3 and 5 cylinders. The M10 shows evidence of being drilled and then stuffed with an oversized bolt to hide their mistake. This wasn't obvious until after the intake was taken off. I discussed and mentioned that I was changing all the intakes from 3/8 to M8 originally, aforementioned, and Raul stated clear understanding. I explained for his understanding that intake bolts being 3/8" to a M8, after mentioned, is only a couple of thousands and you complete service without drilling, and using a M8 tap directly into the 3/8 holes that were being fixed. This was clearly mentioned to Raul. I'm sure he was aware of this and did he decided not to fix this, hide it, and aforementioned, he told me, sincerely and without a doubt, All intake bolts were updated to M8 and found to be a lie. It's still usable but you can't drill out those holes and more and and this limits the surface life of this block. And not giving a warranty to this head problem such as a pulled rocker stud, based on my discussions with other, professionals, business people, and friends, who believed strongly that he should have warrantied this. Travel time, wear and tear, gas, and time. I mentioned to him that I had severe back trouble and for him to treat me like this is just wrong. I relied on friends and family to help with this and it's taken forever to get this done because I can't just have everybody come help me every moment that I need them to get anything accomplished on this. A good amount of time has passed, and that time cannot be recovered. I'm out time, the cost of drill bits that are hardened,and pins. A gasket set, and bolts which have to be zinc hardened, and must be M10 1.5 by 30 to 33 mm which are about a hundred bucks. I wondered why, when I picked it up, he dropped the bill from 5900 to like 5200 and handed me back $700. I know he must have felt guilty, he could not tell me what the problems were, and he's been unprofessional to not warranty this and take care of the problem himself. So if Raul does good jobs for a lot of people he fell short with me and this is why I'm leaving this note because I want people to be aware that this happened and that he's allowed me to have pain suffering monetary loss and time that cannot be recovered, but instead he didn't care. I read the reviews before I came to him and saw some that were questionable but most were happy to have Raul do the work. I am trying to be nice, clear, and impactful for you to understand that directions that you give Raul may not always be followed, and any of those directions that he may hand out to his employees, well you know the risk, and if they screw up your block or miss a drill or tap, I would hope for a better outcome, but this report is to show how he did not help with a better outcome. You deserve this Raul and I hope you the best in the future because what I found shows deceit poor execution of instructions lying and failure to be professional in making a customer happy.

I cannot recommend Raul and the team at Remarkable Engines enough. I originally brought my 2012…read moreDodge Ram 5.7 in for a camshaft and lifter replacement. When I first went to pick it up, there were some serious issues--the truck was vibrating and the check engine light was on. ​This is where most shops would make excuses, but not Raul. He took full responsibility and went completely above and beyond to make it right. Instead of just patching the problem, he replaced my entire engine with a brand-new rebuilt motor at no extra cost to me. I walked out the door for the original $4,000 quote with a fresh engine and a truck that runs perfectly. ​It is rare to find a shop with this much integrity. Raul stands behind his work 100%. If you want someone honest who truly cares about his customers and the quality of his builds, take your vehicle to Remarkable Engines. Thank you guys, Rob G

I brought my car in because it was making a noise every time I started it. I was told the timing…read morechain needed to be replaced and that it would fix the problem. I paid approximately $4,400 for the repair, but when I got my car back, the exact same noise was still there. I contacted the shop and was told the car was fine and to ignore the noise. I was also told the repair was covered by a six-month guarantee. When I brought the car back under that guarantee, I was then told the noise was caused by something else and that I would need to pay for additional repairs. When I asked for a refund because the original issue had not been fixed, the owner became angry and used profanity toward me. I understand that diagnoses can change, but I expected the original problem to be resolved or for the guarantee to be honored without being charged for more repairs. Unfortunately, my experience left me very disappointed, and I cannot recommend this shop.

I became a Desert Heat fan several years ago when Kevin and Kurt helped me solve a problem while I…read morewas at a neighboring business and they didn't even charge me. I have used them for almost all of our auto repairs and maintenance and have always been very satisfied with the quality of work and the reasonable prices. However today I came in and didn't recognize anyone there. Everyone seemed friendly enough so I didn't have any concerns. I was told the driver side door latch needed to be maintained not replaced and the driver side electric window motor was dead. I was charged $238.00 total when the part itself costs between $37.00 (carid.com) and $53.00 (amazon.com). This means I was charged between $201.00 and $185.00 to remove the door panel, grease the lock and install the window motor. I have removed door panels before which takes between 10-20 minutes tops. I have never installed a window motor, but I expect it to be a 30 minute job with another 10-20 minutes to grease the lock and put the door panel back on. I think a more fair and reasonable price would have been closer to $150.00 rather than almost $250.00. None of this is really a catastrophe, but I didn't appreciate my car smelling like a tobacco factory caught on fire when I picked it up. I refuse to give them a 2-3 star rating simply because this could be an anomaly and if Kevin and Kurt are still involved I am willing to give the place another chance. It is extremely difficult to find good, honest and affordable mechanics and I hope I won't have to go on the hunt again. Sorry I missed you Kevin and Kurt!

I've been to 3A Automotive and Diesel a few times now with my vehicle, which recently had its…read moreengine replaced by a different shop I no longer trust. Kirk, the service manager, has been a big part of why I keep coming back -- he's down-to-earth, knowledgeable, and easy to talk to even when I don't fully understand the technical side of things. I really appreciate their communication process, including texted reports and photos of the work being done. So far, everything they've done has been straightforward and honest. When I've questioned their diagnostics or recommendations, Kirk has taken the time to explain things clearly and has even reached out to Jasper (the company that rebuilt my engine) just to help put my mind at ease. That level of follow-through means a lot, especially after a bad experience elsewhere. My one significant complaint is their shop fees. These charges aren't itemized as a "shop supply fee" or anything specific -- they just appear as a flat fee, and they're not disclosed anywhere in the initial quote. Most shops I've dealt with cap this type of fee around $50, but I was charged $90 on one occasion. Not listing this upfront feels misleading, and I think it's something customers should be made aware of before authorizing work. That said, trust in the actual mechanical work matters a lot to me, and this shop has earned that trust. I'll continue bringing my vehicle here, but I'd strongly encourage them to be more transparent about these fees upfront -- it would go a long way toward making an already good experience a great one.

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.
