Great service, great communications and proof that there are mechanics in the metro area that care about their craft. Awesome job!!! Just remember, you get what you pay for. read more

Quality service from the moment my guy and I entered the building. The process was smooth from start to finish. We highly recommend and will definitely be returning. read more

AAA+++ Top Tier service! Brian was very helpful with a cold air intake on my F-250. I just found these guys and couldn't be happier after dealing with the dealership. Will be back.... read more

First, let's start by saying this. $10k spent at this shop for my husband to get handed back a truck that literally would have killed us had he not known this truck as well as he does and decided something was wrong and slowed down to 2mph. The brake calipers were replaced and they didn't complete the job correctly so a bolt either was not put back in or lock tight was not applied and it backed out causing the caliper to move and get lodged between the rim. Ultimately this destroyed the rip causing it to bust and the truck went off the road. Next, they replaced fuel lines going to the fuel bowl and did not install them properly so diesel was going all over the engine and ground. Luckily, he was able to correct this issue. We lost a half a tank of fuel because we didn't realize it was spraying everywhere until it was too late. Next, the fuel line that was replaced was routed over the valve cover and they did not even take the hard line out that was "replaced" it was just left there! Next, they said they replaced the injector gaskets (with the harness), funny thing- they were informed those had just been replaced. So we knew one had a broken clip in the back and low and behold we get it back and magically that clip is still broken yet it was replaced? They kept the truck for an entire month and still couldn't complete things correctly. Pro: they managed to replace battery cables and terminals correctly. So if this is what you're needing, highly recommend....otherwise GO ANYWHERE BUT HERE. As a Navy Veteran myself I expect honor, courage, and commitment from any business just as I give these core values myself in anything I do. This shop has miserably failed to uphold simple values. Communication was poor at best, however the owner did jump in after it hit the month mark and worked on the truck to get it out of the shop for us and he had better communication than the guys he employed. However, in our opinion, your weakest link is also the face of your company just the same as your top mechanic. They are currently "fixing" their mistakes. Will fully update this review once they have corrected and fixed their wrongs. read more

See all

I can't say enough about the team here at Diesel David. Colin and that whole crew were fantastic with being crucially thorough with my potential issues of my vehicle. They keep it all honest and if things do not need to be repaired they will not push that on you to make a dollar. So once again the service and professionalism was top notch. They also gave me a loaner vehicle to get from point A to point B while my truck was in the shop for the week. Since I'm an out of towner working in Atlanta this worked out fantastic. Can't thank this establishment enough for taking great care of my vehicle and making me feel at ease with the whole process!!! read more

David is an incredible mechanic and runs a great shop. We had a 2013 Ford escape that another shop was going to charge us $1300 To fix a coolant leak problem. I wanted a second opinion so I took it to David. After doing a full diagnostic, David found that it was an overflow cap problem. He saved us over a thousand dollars. He said that he would only replace what was needed. I had him look at the vehicle and none of what the other shop was recommending was needed. The problem was something extremely basic and David kept it to the basics. I can see David and his shop are incredibly honest and they do not up charge for anything that would not be needed. We need more mechanic shops like him around that do things the right way and are trustworthy. David has my full respect. read more

So thankful to David and his team. I am purchased a diesel sprinter van and every possibly question I could think of and throw their way they had an answer and solution for. The customer service is top notch followed by very knowledgeable and trustworthy actions. As a woman I'm grateful to have a place that I can trust to take my vehicle and not worry about being taken advantage of for my lack of mechanical knowledge. Again thank you so much. read more

Fantastic shop for my 2002 Chevrolet Duramax! So pleased with the quality of service! Makes it fun to keep the old truck rolling!

I had an electrical issue with a fan blower resistor which also caused the truck to idle rough and only idle in gear paid $417 for 2 hrs Diagnosis said 3 injectors no functioning wanted to take all out send to he checked $2800 if 3 were needed $4800 if problem still exist check ECM or FICM. So I towed it home took out ECM sent to Diesel ECM repair on Monday had it refurbished and back home on Saturday installed itran like new for $495 with free shipping both ways. That's my experience. read more

I brought my truck to these guys I heard david was very good. his flunkies are inexperienced or under qualified or both or maybe they just rip people off. they diagnosed my truck for 850 with a bad egr cooler oil cooler which they said was incredibly unlikely that they have only replaced two oil coolers since they been there... how long have you been there? so 859 to find out it's and egr an oil cooler and a head gasket only 15k to repair. I have pulled the truck and taken it to another shop. so after the 850 John wants another 500 to re install the egr so it will run. his 500 on top of 850 somehow comes to 1600 dollars?????? I refuse gonna tow the truck when I get there 20 minutes later Johnathan says "my tech is a bit of a completionist your truck is together and ready to drive" so you guys put it back together in the 20 minutes after we got off the phone??? these guys are crooks. Find a different mechanic read more

Amazing work by the mechanics here especially David, they're very trustworthy and they'll be completely honest with your truck. Their prices are also great compared to other repair shops. I came to get a boost leak issue and coolant leak issue resolved and i'v been to many other shops and I can say that this shop is worth visiting. read more

I would recommend Diesel David. My truck issue was a major problem. Diesel David helped me throughout and was really helpful. I won't be surprised to see this company soaring with success in the years to come. His business ethic and skills will set him above the other mobile mechanic competition. read more

Diesel David - I was told by David to either sell truck cheap or buy used engine $13k This is what I learned the very next day from Ford dealer - Auto Repair Near Me - Woodstock, Georgia

I was really disappointed with how much I was charged for such a poor/incomplete job. I will never trust this company again and I certainly won't recommend them to any one I know. read more

I'm a DIY kind of guy so I know a thing and won't be fooled. However, it's all about time...I have none! Dave came to me, replaced my upgraded left side inter cooler pipe from a typical turbo boost blowout in half the time it would've ever taken me! Easy explanation, knowledgeable, quality quote, fast service, time saving!!!! Thanks, Chris read more

I had an old infiniti g35x which i had not used for a long time and the battery died. After a bad experience with another mechanic booked an appointment with David online. I got a call from him within an hour confirming the appointment and telling me what he would be doing and how much it will cost. He was able to come early and fix the minor issues and start up the car(which the first mechanic was unable to and said he needed to do 3 tests to figure out whats wrong). David suggested some repairs and again explained the cost involved. During the second appointment he was on time and dinished the repaiir work on time. Next time i have any issues with my car i am calling David as i know i can trust him and he would do a great job read more

David was quick and responsive regarding all my questions. He quickly diagnosed my Gas Camry 07 and gave me a comprehensive and honest review of things that needed work. He was punctual and even changed my car key batteries for free !!! Showrooms had quoted me more than hundred bucks to change and reprogram my car key I highly recommend David for car evaluation and repairs read more

Dave was very helpful in diagnosing my truck project. He was able to identify and resolve the issue and talk to me about WHY it had happened. He left me with the confidence that if I back myself into a corner again, I can count on him to come by and lend me his expertise. Will definitely use him again. read more

I used Diesel David to check out a chevrolet silverado 2500HD with the Duramax Diesel engine. I was very impressed with David's communication and punctuation for keeping our appointment time. David's experience was quite evident, I usually fix all my own cars but not having equipment or experience for a diesel engine I use David. I'm so glad I did,David hooked his computer to the truck, and after a short drive around was able to tell the health of the engine. David's keen eye for detail helped point out a leak in the water pump that I hadn't seen. Altogether David's honesty, excellent attitude, flexibility, and experience, are but a few reasons for my full endorsement of his service. I will use his service again. FIVE STARS read more

This company's service is 2nd to noon. They come to you, charge a fair and honest price, and do the job right the first time. Not to mention they are extremely friendly and easy to like. Can't say enough great things! read more

My classic truck had a brake issue to the point where it was not drivable. They came to my house, diagnosed the issue, told me what parts I needed, and then came back to do the repair when the parts came in. Not having to call a tow truck and worry about my truck sitting outside in a parking lot somewhere while the shop works on 100 other cars before mine gave me some peace of mind. The fact that they were so knowledgeable, professional, and communicative throughout the entire process guaranteed that I will use them again. read more

David is extremely professional, knowledgeable, helpful, and honest when it comes to dealing with anything car related. I like to think I know a lot about cars, & don't we all... But I'm well aware of my shortcomings & David fills that gap. No gimmicks, just straight up honest work for a good price. Can't say enough good things... plus, he's mobile ! read more

David is awesome. Helped me a few times and even picked me up to take me back to my car that was in a parking lot, where he fixed it. Very nice and honest guy. read more

Lying Diesel David Due to the overwhelming positive reviews and self-proclaimed expertise in diesel repair, I gave David a chance on my ailing fathers Dodge Ram 2500 Cummings Diesel engine. The main issue with the truck was that it wouldn't start at times and because of my father's health condition, he wanted everything in the truck fixed so he could sell it in good conscience. I should have seen the warning signs, but my focus was more on my family then this (lesson learned). When David was made aware of the circumstances, he gave us a low-ball (insulting) offer of 10k for a truck that easily fetches 25-30k (same miles, condition & year) on auto-trader. We respectfully declined. He seemed very excited about the repairs and told us all of the issues it had and we soon saw a growing repair bill. Initial quote was $3,500... Towards the end of the diagnostics, he said "oh there is also a diagnostics charge"... I was not made aware of this up-front but complied with the diagnostics and approved the repairs (based on his "expertise") He calls me up later the next day and tells me now he made a mistake on the initial quote and that the repair would be $300 more. I explained to him this was getting very high very quick and we cannot afford this already high bill. During the repair process there were several delays and miscommunication on Davids end. From missed appointments, to forgotten to order special parts, to taking the truck from our property against our original agreement and our consent. After he brought back the truck, my dad took it out for a test drive and we both soon discovered that the truck was in even worse condition than ever before. The steering had a 3 inch play in it.... So bad that we had to end the test ride and brought it back.. My dad was upset, given the amount of money that we spent. David said he would back the next day to take a look at it. One weekend later, he finally stops by and the truck would not stop (keep in mind this was what he was brought in initially). He tries and tries and after about 30 minutes realizes that one of the battery cables was loose and was able to resolve this issue. This guy had the audacity to tell me there was a secondary diagnostics charge. WOW... I called him up and explained to him how that makes any sense, and he finally agrees. We spend an additional $1000 dollars for repairs to fix the alignment, but the problem persisted. Finally, we decided to tow our truck to a local diesel repair shop and showed them the problems along with the repairs completed. They were astonished at the repair bill and over charges. Looking at the repairs, they told me it appears to be the work of an amateur and with the truck lifted, pointed out the issues which I was able to confirm. The boots on both axles were ripped during Diesel David's take apart, resulting in exposed grease to the outside guaranteeing a premature failure. The parts that he used were clearly cheap chinese aftermarket parts. The issue with the steering was the gearbox, which they were able to fix for under $800. At best, David is a great backyard mechanic. If you need your oil changed, tires rotated or windshield washer fluid replaced... He's you guy... anything outside of that, I wouldn't trust him. I am upset that David decided to take advantage of my parents and the condition they were in. From the up-charges, failed promises, failed appointments and cheap parts used. If you decide that you want to use him for your next repair, ask yourself this... Why doesn't he have a repair shop? Having a mobile repair guy sounds great, but you are risking your safety and the safety of others by using him. Buyer beware. read more

So i took my 2006 duramax for a new rear axle from a insurance claim, i got a quote not to long after i dropped it off for $11,000 yes you read that right. Then he charged me for a diesel diagnostic test which is the cheapest idk what that has to do with the axle but after that he proceeded to tell me my head gaskets were gone which they are not ive had them tested since also with the rear axle blown out it wouldn't move the rear tires so he put it in 4x4 which any shop especially a so called diesel shop would know when put in 4x4 forcing all toque on the front wheels would you guessed it shatter my ti rods then they refused to pay for them after they broke them i got all this work done from another shop for slightly over $6000 not $11k he also quoted me on Head Gaskets which again were not bad for a little under you guessed it $11k and the take my experience and learn from it read more

They had a mechanic onsite within 2 hours of the first phone call to do pre-purchase inspection. Honest mechanics give the pros and cons when doing a PPI. The mechanic called me and immediately explained the truck was very cold blooded and operated poorly!! So glad to have Yelp to help us find great mechanics that do what they say they will and save us huge hassles later. Thank you Diesel David! read more

My son borrowed my truck to move in Kennesaw, I live in Chattanooga. When my truck broke down I called and spoke to Mallory. They went to his house to look at it and when it needed to be taken to the shop, after hours she volunteered to be there when it arrived. NEVER have I had so much communication from a mechanic while they worked on it. When I went to pick it up they had a part that came in damaged. Once again after hours David made a special trip to Cartersville to get what he needed just to make sure I got my truck when promised. Sure wish they were in Chattanooga because I would NEVER take my vehicle anywhere else. Highly recommend Diesel David. read more

I came across David after seeing his great Yelp reviews- my car had broken down and since car issues always seem to come at the worst time, I was looking for a mobile mechanic to avoid towing cost. David was professional, honest and friendly and helped make the stress of my car being out of commission a little easier. I ended up having to purchase a new(to me) car and will be having David come out for a pre-inspection and will be using him for all my future mechanic needs. Thank you again! read more

David has worked on our old 98 dodge diesel a few times now and always professional, delivering top notch service and repairs. Both onsite repairs and at his shop. Does what he says ahead of schedule, at a fair price. Highly recommend. Guarantees his repair work, which is great as a consumer looking for good value. read more

I would highly recommend Diesel David. He showed up exactly the time he said he would, did the repair quickly at a fair price. I have been looking for an honest diesel mechanic for many years and have found one finally with Diesel David. read more

This review is a little late, Diesel David did some engine leak work to my Buick Enclave about a month ago. From when I first called he was pleasant, accommodating and willing to work with me. I called him on a Thursday he found time to fix my car Friday morning and within my time frame. From what I seems once I picked up the car it was driving better. I said I was going to take it to another repair place just to verify the work had been completed, but haven't had the time, will update when I do this. But overall David was great and will be going back to finish the rest of the repairs read more

Spoke to Dave today to get advice on purchasing a used diesel truck. He is very knowledgable and took his time to answer all of my questions. He also offered to meet me at a dealership and do a pre purchase inspection for a very reasonable fee. Thanks Dave! read more
