Our experience was absolutely horrible. We took our 09 Toyota Highlander to Cartec this morning for…read morea free inspection (to continue the inspection the needed to replace the valve cover gasket for $330) because our car kept dying when we would come to a stop, we gave them our car for 3 hours and then got a call back from a lady who said that the total would now be $550 because they broke a solenoid that was "frozen in the head of the engine" instead of calling us before they decided it would just be better to break it out. On the phone since they decided they wanted us to pay for it we decided it would be smarter on our end to threaten to take them to court because we're not paying for a part that you broke without asking, Jerry (the owner) said on the phone that he would get the costs covered and he would message us when they are done with the car. Once we arrived to pickup our car the battery light was on (it wasn't before) and they still made us pay the $330 for the valve cover gasket. We left, went home, opened the hood of our car to see that the alternator was not even connected to the car anymore and the bolt was gone, the cover on the top of the battery was just sitting on the side, and the alternator wire was covered in a bunch of electrical tape. So, we take it back to get our alternator hooked back up and Jerry was being very unethical and not understanding at all about the fact that they left our car like that. He finally found a bolt that fits, after trying 3 other ones of which fell into our engine bay, and then sent us on our way.

So, I am a son of an old school mechanic. I am accustomed to mechanics "talking" to me about what…read morethe problem is and finding creative, economical solutions for auto repairs... so maybe I'm a bit of a dinosaur. Took son's vehicle in for issues, charged $140 for diagnosis that was really just "replace single thing ($3k) and by the way, we recommend you do things you didn't even bring the vehicle to us to look at...(additional $2k) and really you should just get a new car since it has 90k miles on it." (On a vehicle that is known for 200-300k miles and consistently one of the top 10 vehicles for reliability) Then it got interesting. After a Google review detailing the above, my son starts to get harassing texts telling him to remove the review. Maybe these guys do good work... Lots of positive reviews. I am not a fan of bullying behavior, but will take the high ground here and simply suggest they work more on effective interpersonal communications with their customers and less on policing the reviews and harassing people who have bad experiences with them.

So happy to have found David Woods and Lug Nutz! I'm new to Tulsa and one of the first things you…read morehave to find is a good mechanic. I'd been to one and it was okay . . . another charged a ridiculous fee UP FRONT before even knowing the issue . . . so one day, driving by Lug Nutz, I thought, "I'd like to find a great solo practitioner whose business depends on doing a great job so I will come back" (what a concept, huh?). I decided I couldn't do worse than what I'd already experienced so I gave it a try. David is attentive, clearly knows his stuff after many years of working on vehicles in different settings (dealership, fleet work, etc.), and as I had to wait, has provided a pleasant little waiting room that is clean and comfortable. His prices are wonderfully reasonable. I told him all I wanted was someone who was honest and would be creative in finding the solutions to my car's problems, and he is on board. I'm recommending him to everyone I can!

Now it's been 7 months since I have seen my car still no replies to the 20 phone calls I have made to David O'Brian. I would NOT recommend this place for any reason. Plus the office receptionist is always rude and abrasive to all my Questions and still no positive information about my car. This is a deplorable business. A huge lack of concern for a timely repair job. no way never again

Hands down best customer service and car care I have ever had!…read more My car began having issues as I was out of town. Since this was a Saturday many car care places were closed, I happened to find Sinclair after a quick search of finding someone who was open on a Saturday afternoon. Sinclair was quick with their service, but also took time to answer questions and explain what the problem was with my vehicle. When I followed up with additional questions they clearly explained things in a way I could understand. They also took the time to show my husband and I what was the source of the issue. We also happened to share that we had a nail in the tire that we noticed when it was loaded up on the tow truck prior to our arrival, mentioning that we would need to go get the tire taken care of after we left Sinclair. They then went above and beyond to taking care of the screw that was in the tire. A day later they called to see if I made it back home safely. Thankful for the care they showed even after we left! We are beyond thankful for the customer service, attention to detail, communication and reliability! We plan to be back!

I was at that shop at 8:05 Monday morning. Another guy showed up around 9. At 10:00 he wrote note and stuck it in door. I asked if they usually didn't open shop. He said they'd had his vehicle for 3 weeks after promising it would be ready in 3 days. At this point I decided that even though I'd wasted 2 hours waiting around, I'd been spared a worse fate. A friend's shop was nearby and I went to visit him. He called around and got a recommendation for Harmon's. Adam fit me right in, drove around with me for a good 20 minutes and said noise was wind noise NOT differential gone bad. Plus I was complaining that the rear wheels would shudder sometimes when I'd accelerate from a complete stop. He couldn't recreate this. At no time did he make me feel dumb or as if I was imagining things. He was knowledgeable and thorough, putting vehicle up on lift and checking underneath. He even spoke on phone to my husband about work done in past and his diagnosis. I was going on a 1,200 mile trip. He reassured me that vehicle was trustworthy. Didn't charge me. My husband said give him a hundred as he just saved us many many hundreds by being honest and decent. The other guy and lady working there were friendly and helpful too. A totally impressive operation!
