North Texas Diesel, Automotive and Performance LLC 2501 Worthington Drive, Denton, TX 76207

"I had my 6.0 Ford in 5 shops and Jeremy and Nancy matter figured out why it was having problems then fixed them for the best price I could get!!! Anyone who doesn't think NTX Diesel is the best shop around you are out of your minds!!!"

"I paid $2,300 for complete rear axle bearing service. Rear axle pinion seal and speed sensor/ABS sensor seals were not installed properly. Rear axle lubricant leaked out during drive back to Illinois. Had to spend another $400 plus for the seals to be installed correctly upon returning. Attempts to contact the business and its owner, Nancy Matter, was met with negative results. Small claims lawsuit pending."

"No "BECAUSE you are a WOMAN" discounts here! This is an experience we had in 2020! But we still feel the same way! My wife took our Ford F-350 to a local shop and was given an Itemized estimate totalling over 10K back in 2020. I had read a lot about NorthTexas Diesel, Automotive and Performance LLC so we decided to get a second opinion. When my wife called to set up the second opinion with Nancy, she responded it sounds like you got the "Woman Discount" they both laughed knowing that it meant the shop was treating her like she didn't know anything. We took our truck to them and they diagnosed it. Not at all the same services needed as previously recommended and we even replaced 4 injectors instead of the 1 recommended. Our total bill out the door was $6700. The truck runs amazing! They took our truck that we paid $6K for and turned it into a $19K truck that we know will be sound for all of our hauling needs! I can't thank you enough for the piece of mind that you have given us knowing that we can take off in our truck and not worry!"

"WOW!!! If I could give 10 STARS I would! Nancy and Jeremy go over and above! We took our F350 to another shop and we played the "We think it is this" game to the tune of $1500.00. We found ourselves stranded with an Autistic child and 100 degree weather. We took it back to that shop and "they fixed it again" Drove it home, less than 50 miles and found ourselves stranded AGAIN! We called Nancy and she immediately responded with "There is an high pressure oil leak somewhere." We took it to NORTH TEXAS DIESEL, Automotive and Performance LLC and the very next day she called and with an explanation and an estimate that was less than what I had already paid the other shop. We have used this shop multiple times and everytime they have been fair, thorough, knowledgeable and reasonablly priced. I now live over an hour away from their shop, but after this experience, I would drive across Texas to take my truck to them! You can't go wrong with NORTH TEXAS DIESEL, Automotive and Performance LLC!!"

"I wish I could give ZERO stars! Avoid Nancy and North Texas Diesel at all cost! I took my 06 5.9 Cummins truck to NTX Diesel 10/4/2021. I had and injector issue in cylinder 1 that caused the piston to melt. Nancy quoted me a decent price to rebuild my engine. I also asked for a new set of injectors, coolant bypass and to inspect my clutch since it would be accessible. I was told it would be about 4-6 weeks to get my truck back. Finally in late December I got my truck back (after a lot of excuses). They didn’t install the coolant bypass, they forgot. I left the shop and immediately noticed my clutch was slipping. I returned to the shop and the mechanic told me he wasn’t told to look at the clutch even though I had reminded Nancy multiple times. They did agree to change the clutch for the cost of parts only since they had overlooked the inspection. Once I got my truck back I decided to put some miles on it to break in the engine as I needed it for an upcoming trip. After about 100 miles the “new” clutch began to make noise. I returned the truck before Christmas to have it fixed again. I got the truck back in early January. Once again I decided to put miles on the truck to break it in, again, after about 50 miles the clutch began to make noise again. I returned the truck again for repairs which were completed by late January 2022. All I ever got from Nancy were excuses as to why my truck wasn’t completed on time or correct. Fast-forward to 7/2023. I was headed out of town with my camper and the truck decided to throw a couple of rods out of the side of the engine. This was 18 months and 30K miles after they rebuilt my engine. Naturally I decided to take my truck to a different shop to get rebuilt this time. The new shop tested my injectors since they had them out. Three of them didn’t meet the specs anymore. I called Nancy to see if she could provide the information I needed to get them replaced under warranty. When I made my initial call to Nancy she started right away with the excuses. She told me she was out of the office and could not look up my information that I should call the next morning. Over a two day period I have tried to call her 4-6 times, either going straight to voicemail or no answer. My new shop contacted the Bosch rep to see if he could help. When he called her she refused to help at all with the invoice for my injectors. Now I have to buy all new injectors instead of returning the bad ones through warranty. I’m beginning to wander if she even gave me new injectors when she rebuilt my engine. Avoid Nancy and North Texas Diesel at all cost!"
