Trenton at Mad Diesel Workz had my truck for 5 days and couldn t fix the problem. He tells me to bring it back @ $200 per hour for diagnostic. No thanks I m never going back. Waste of time and completely unprofessional.

Not even sure how they received stars. Worst shop I have ever dealt with. Well, I thought at first. ZERO COMMUNICATION. I mean ZERO. They messed up my truck and sent it to their buddies at Chino Hills Transmission. That was even worse. Cost me $4,000 and problem still exist. Don t even want to take back with their warranty knowing my truck will be gone again for 3 months working on it

Excellent shop spoke to Trenton and I had a feeling he was honest and very knowledgeable on diesels. Visited several shops in the Riverside area and ALL told me the motor was tired and needed replacement. Four days later at Mad Tech Diesel and the truck is running better than before with 1/10 the cost. Due to the length of my stay on Earth when you see a clean shop, tools organized, office and keyboard clean, 9 out of 10 you will received great service. Thank you Trenton for the great customer service and getting my truck back on the road. Best regards Al

Professional powerstroke techs experienced with the latest technology for computer detail service. Organized and the customer service to go with it. I found it to be the best place to do diesel service. I left a very happy customer.

Have been looking for a good desiel mechanic since moving to California and finally found it. Came in with a handful of issues on my 2014 Ram 2500 Turbo Desiel that I had just purchased and Trenton was super helpful in making sure we resolved them all.He was happy to diagnose the issues with me and talk through the repairs I needed before starting any work to make sure I was on board.Dropped off and picked up my truck today and it is running better than ever. Would not take my truck any where else!Good pricing too!

Called mad tech a Thursday afternoon and let them know I m planning on flying in and buying a private party diesel and wanted a shop to do a quick 30 min inspection before I did. Every other shop either said they re too busy or they don t deal with duramax. Guy over the phone was super polite and said they can squeeze me into the busy schedule. Got to the shop all the techs were very nice and the main guy I dealt with, Trenton, is the man! Guy is knowledgeable, thorough, and made it a great customer experience, if I ever need diesel work done in LA they will forsure get a returning customer out of me :) thank you mad Tech Diesel Workz!

Trenton and his crew at MadTechDiesel are top notch. Great prices and great service. Trenton communicates very well and kept me informed of the issues he found in my truck and updated on his progress.You always hope that everything goes perfect, but the sign of a really good mechanic is how do they handle it when there is a hiccup. Well we did have a small issue pop on the test drive, but Trenton showed his professionalism staying cool, handling the issue easily and immediately. Like they say, smooth waters don t make skilled sailors...My truck is purring like a kitten, and it drives like a bat outta hell. I d confidently recommend his shop to any of my friends.Thanks again guys, you rock!!SincerelyIsaac W

Talk about being a master of your trade, Trenton has to be one of the most knowledgeable mechanics out there. After dealing with Mad Tech, I'd be a fool not to recommend them to anyone looking to get some quality work done.

When you see people advertise or a review of an honest mechanic your first inclination is to say Sure, yeah right, everyone says that ! Let me tell you first hand my experience with Brystrom Automotive today...I m in the medical field and have a Diesel engine vehicle..during this pandemic I clearly have lacked sleep..after work I went and got fuel..I wasn t paying attention and pressed the gas button with the green sticker assuming it was diesel...it wasn t..it was regular gas instead! $19.50 in I realize what I did and stopped pumping the gas...I knew I couldn t start the engine or more damage would happen..I randomly googled any mechanic to service my car ASAP and came upon Bystrom Automotive! Panic stricken and running on borrowed time started rambling on to the man who answered my call to what just happened..Trenton was his name..he put me at ease immediately and said Don t worry I ll take care of you . He sent a tow truck to get this nurse who was a damsel in distress within 15 mins or so..had my vehicle towed to his shop all the while thinking about the expensive screw up this was going to be.. I get to the shop and he and his boys get to work on draining the fuel and flushing this and that and whatever else needed to be done! Not only was I done in just a a couple of hours or less but at the most decent and way reasonable price ever given in ANY car repair I ve had! Saved my money. Saved my time and gave me peace of mind by walking away content feeling like I came up in my karma , today! Paying it forward is what we all need to do at some point in our chaotic lives! I can t tell any of you how HONEST & RESPECTFUL this crew at Bystrom Automotive are! To all the ladies out there who may be or not be like me if you have a car that needs work and your not sure what s wrong with it or are afraid you may get ripped off or taken advantage of because we lack knowledge regarding automotive repairs THIS IS THE PLACE TO COME TO! Point Blank Period! Honest Mechanics and Kind Hearted Kings is what they displayed and represented to me this evening! Thanks boys for helping me out at the last minute in an area that was unfamiliar to me as well as making me feel safe and blessed to cross paths with! I totally lucked out..I thank you and my family thanks you! Overkill on this review you say...NOPE JUST FACTS! Come here and you ll save and your time trying to find a better deal! Thank you times ten.Love + LightDrea

Trenton is what I like to call a guru of the 6.0 diesel along with the rest of the powerstroke line...as an equipment mechanic myself I can say for a fact that his knowledge far surpasses many others in the field.. in a short period of time I learned allot and would recommend his shop to anyone in southern California looking for honest work.. look no farther this is the place
