These guys are the best! They were so kind and quick to help me. They saved the day on a Sunday afternoon so my kids and I could get back home to Utah, and we are so grateful! So glad these guys were the ones who showed up in my google maps search.

Great service when I was in a bind. Vehicle was acting up on way to work. Found Monaghan's in map search. Called and they got me in right away. It was a simple fix, done quickly, but they were also thorough in checking every other option, as well. I can see why they are busy. Highly recommended!

The smoothest experience I have had with any mechanic. Our technicians James and Chad were professional and immensely helpful. In an emergency they were able to diagnose our vehicle, and do everything in their power to get us back on the road as soon as possible. Not only did they facilitate our mechanical needs, but we're also more than hospitable. I can't recommend them enough.

We highly recommend this auto shop! Life saver! We needed a new starter so we googled this place contacted them to explain We needed this done same day as we needed to get back to California. Chad started the truck at 1:00pm had us on the road by 4:00. Like I said LIFESAVER! Thank you Chad and all Monaghans employees you guys are amazing!

My gf and I brought her car in to have the brakes checked due to them making a loud grinding noise. We didn't have an appointment, but Monaghan's was able to squeeze us in.Mechanic discovered one brake pad had been worn completely down and the rotors were not good anymore. He replaced both front brake pads and rotors for an extremely reasonable price.Ended up having to bring the car back a few days later bc the brakes were making a grinding sound again. He ended up warrantying out and replacing the front brakes&rotors again and also replacing the back brake pads free of charge.Really happy with the quality of service we received at Monaghan's. Staff is always friendly, service is great, and they don't try to nickel and dime you. We will only come to Monaghan's when our cars are in need of a mechanic.

DO NOT RECOMMEND!! They failed to give me the correct diagnostic for a change of AC system which left my car in their hands for a week but was still unfixed when I picked it up. Their team had a lack of understanding what was wrong with my car which left me worried. DO NOT TRUST THIS PLACE. As the days passed by I always was failed with communication of what was going on, just for me to find out that before their closing time that my car was not working & something additional was not working. I m left with no AC fixed but still had to pay for the labor & parts & on top of everything they broke my dashboard but didn t bother to tell me, it was a very upsetting experience I would never come back here again.Service: A/C installation & repair

The staff here is very friendly. I had many services done this visit, and they had it all complete by the following day. Prices are reasonable. I will definitely go back here for repairs.

James replaced my water pump and completed an oil change, communication was great. I would recommend Monaghans if you are in the Las Vegas area.

DO NOT TAKE YOU CLASSIC CAR HERE!!! I had my car in for an intake manifold and they did a very sloppy and poor job . I had to give them the car back 3 times because it wasn t running properly after they serviced it. They seem like they have no idea how to work on classics and my car has never run right since they touched it!

These guys are pros!!!If my car isn't running perfect it stresses me out, didn't know what was wrong. Took it to Monaghan's and they checked everything front to back. They were thorough, fast and fair. I've found my go to mechanic.

Beware There Not diesel specialists. I went out of my way taking my ram 6.7 for a cp3 fuel pump replacement, 3 months later the cp3 came loose while driving. Then they blame me saying i tried to intentionally remove it. There also too incompetent to do a proper diagnosis. Checking codes and taking a guess for 300 is a scam. They recommended 2000 to repair none exisent problems. DONT take your truck to this shop. Just go to the dealership.

Knowledgeable mechanics. They were able to repair both of my vehicles one gas and one diesel. Diagnostic was done within a few hours of dropping off. Matt called and went over the needed repairs and helped with the E-Signature system so I didn t have to drive back to BBB shop to sign which really streamlined the whole process. James and we Chad each did the repairs and gave me detailed status updates daily which helped me plan out my week. Overall impressed with the service, repair, and cost. Will be recommending to all of my friends and family and setting up a fleet account for my company!!

I have made two separate visits to their shop, for different repairs I needed to have done on my dodge ram pick up. Matt was extremely friendly and helpful. Both times he got me into the shop the very next day and out the following, just as promised. I am not only extremely pleased with the customer service, but also the repairs that were done, parts used, and the reasonable cost for what I had done. I highly recommend this shop. They are one of the few, if not, the only shop that is open seven days a week. That is a huge plus for many people. I know how difficult it is to find a capable and honest mechanic. I think that Matt and his team at Monaghan s are just that!Services: General repairs & maintenance, Auto engine diagnostic, A/C installation & repair, Air conditioning, Brake service & repair, Oil change

What more can I say about this shop? The manager was very helpful and open about services and cost. Was very thorough and even caught a few things the last shop missed. He was very accommodating and even realized that the fixing was going to be a while, so he gave a pass to spend the time at a local swap meet. He knew I was not from LV, so he even called me to inform that if the plan was to stay another day or not as certain parts were not readily available. But he pulled through and found what he needed to get me home that night. I definitely recommend this shop. Oh, and he's even open on Sundays!

If I could award more than 5 stars, I would. Scott and his crew took such good care of our vehicle and of us! Our Ford E450 6.0L diesel school bus conversion RV was idling rough and shaking, and Scott squeezed us in for a same-day diagnostic, revealing that we needed new fuel injectors. He patiently explained what he needed to do and even showed us on an engine in the shop and answered all of our questions. The entire crew was friendly, hardworking, knowledgeable, ethical, and went FAR above and beyond to get us back in our bus and on the road as soon as possible. Thank you guys so much for keeping the #buslife dream alive!

How the hell does this company have 4. Something stars ? They re either bots or paid for because this company will not only ruin your vehicle , they ll keep your vehicle hostage for months and will cost you in the 1000s to fix all their mistakes . Look at the bbb , this company should be sued

Truck was in the shop for a week, didn t touch it because they were too busy . 90% they re the reason it s still broken from past work done on it. Do not come here they re a bunch of idiots who don t know what they re doing. You d be better off giving you vehicle to a middle school band, instead of these jackoffs.

They told me my car would be fixed within 3-4 days. Its been 45 days and I'm hoping this review gets their attention, because they've been lying to me with non-stop excuses.

I am a disabled senior living on a really tight budget and tried a couple of mechanics to get my A/C fixed. I put my project on Yelp and prayed not to get taken advantage again. The first response I got was from Matt at Monaghan's telling me to bring it by and he would take a look at it and see what was going on with it. Well let's just say it is working great and they warranty their work! Also he kept me updated the whole way and made me a great price. Also customers coming in to pay their bill and he treated them like he had known them for years. I will bring back my car anytime it needs a mechanic to Monaghan's.Service: A/C installation & repair

While visiting Las Vegas I drove quite a ways to get to this shop based on the positive reviews. As a disabled woman driving a 3/4 ton diesel to unknown towns and looking for honest car repair, I was extremely happy I found this shop. They were very clear and honest about what services I actually needed and what services I could defer and pricing, as well as thoughtful about my disability needs. Would 100% come back to this shop.Services: Electrical, Oil change

10/10 I highly recommend this place! Very straight up and honest mechanics! Not only did they fit me in for a diagnosis on short notice; they were able to fix my Camaro and have me back on the road within 2 hours! Reasonable rates that don t break the bank!I will be going back for any future repairs!Services: Steering & suspension repair, General repairs & maintenance

My son s Subaru died in the desert and Monaghan's repaired the engine, and my son drove home 300 miles today and everything worked without a hitch. It s nice to know that we have a mechanic in Vegas for emergencies.Oh, and we just got back from driving it a week in Yosemite, thanks, MattService: Engine repair

These guys are total life savers. They fixed my A/C with no problem. I will definitely be coming back and I highly recommend them for any car. They are not expensive very affordable enough for me.

Charged me $500 for a horribly done rear brake job. Paid him cash only for him to state that he made his pay check for the month. Now my front brakes are squeaking after they told me that they were fine. I went to them frequently, despite being on the pricey side I gave them a lot of business by recommending them to family. Not anymore. They're clowns
