Precision Diagnostics

Had a great experience taking my car here for the first time. They diagnosed and solved an emissions issue that several other shops had failed to figure out, and their pricing was upfront and super reasonable. They communicated and sent me reports with photos and updates via text throughout, which was excellent. Will definitely take my cars here again in the future.

I can’t express strongly enough how great these guys are. Jose is absolutely fantastic at organizing the work, providing clear estimates, and taking appointments, ensuring the quality of the work is second to none. If you live in Chicagoland area, this is 100% the place to bring your car . They are honest and trustworthy and do work to the absolute highest standard. Beyond that, they are wonderfully patient and personable with customers. They have the best team for a precise wheel alignment and take there time making sure the wheels are straight.

This place is amazing. I got my swaybar links done in an hour. Very professional and courteous. Gave me a Veterans discount and did quality work for reasonable prices. I would recommend this shop to family and friends. Combat Engineer Veteran Antonio, hooyaaa!

Came in with some pretty major exhaust problems and they fixed me up within a few hours and kept me up on the details of what parts and what they were doing. Great place for sure coming here again.

been coming here for over a year for both my cars for exhaust work and alignments. the quality of work is amazing. i don’t like trusting people with my cars often but if there’s one shop i fully trust, it’s this place. they take care of me every time and the prices in my opinion are very fair for the quality of work.

Great work and really great prices compared to other quotes I received. The owner, Jose, is awesome and really goes above and beyond.

Jose and his team of professionals performed an engine swap on my 2000 cavalier Z24, they were in constant communication on the progress and advising on the findings making this easy for me to decide what work was need it, over all well satisfied with the work and they also left the car clean when they were done with the job! Great job Precision Diagnostics, keep up the good work. I highly recommend this shop to any one in need of a good mechanic and I have high expectations on the repairs of my vehicles and that is why I only provide feedback on businesses that go above and beyond the line of duty.

Been to this shop a couple times to get some work done on my mustang. The first time to get some mufflers installed, and then to get my catalytic converters replaced. The work they do is top notch, and the quality is excellent. Prices are very reasonable, and everyone I've dealt with has been very pleasant, and knowledgeable. Would definitely recommend this place to everyone.

Great customer service, knowledgeable, and great prices! I just moved out here and now they are going to be my go to spot for Auto Mechanic work!

The owner Jose Ramirez was completely professional and understanding on my issue . Help me out on with my truck in no time. Fair prices on the work his shop did. 👍

One of the best mechanic in Plainfield area reasonable prices honest work best worker team I take my all families car his mechanic shop very very reasonable prices I am so happy at my city of Plainfield one of the best mechanic

I had a loose tail pipe on my Porsche 911 with a sports exhaust system that only needed a couple of touch ups to fix. I called several places to see if the would address it for me and nobody took me, they were too busy being Friday July 3rd and holiday weekend coming up. Until I called Precision Diagnostics and Jose (owner) was super nice on the phone and explained they were busy but he could take my car later same day Friday early evening. When I got there, they took my car right away lifted it and fixed it and in a matter of 10 minutes I was out. No Charge!
Clean place, quick and easy. I will go back again when needed and I highly recommend you go there for repairs and service, you won't be disappointed. The crew is super nice too.
THANK YOU PRECISION DIAGNOSTICS!!!

Had a lift kit put on my jeep very quickly after calling to get an appointment. Very flexible. Charged much less hourly than other companies. I Trust precision with my vehicle even though I don’t trust many companies. Jose the owner, is very honest and only hires people that know what they’re doing. Antonio has helped me the last couple times I have taken my jeep both for alignment and lift/ alignment and he has been so helpful and honest. First time going and after testing vehicle my alignment ended up being ok which any other shop would have charged me full price. Precision did not. They were honest and helpful. Would recommend and do recommend precision diagnostics to anyone who wants to go somewhere where they will actually take their time with your vehicle and do it right.

Percision Diagnostics was highly recommended to me. I took my Mercedes in for Service B and a issue with my driver window. They definitely did not disappoint. He was very informative, and friendly. I felt comfortable letting them do the work. They got me in quickly for my appointment. Returned my baby back like new. Would definitely recommend!!

I was very happy with my services today they worked on both mine and my daughters car. I have used you once before best part you run an honest and affordable business. You walk away not feeling like you over paid. I love to support small business and will be telling anyone that will listen when they ask if I know of a place to get services. I will gladly tell them "I got a guy" Thank you to your entire team.

Excellent place! They put on a new exhaust and tips, which look and sound amazing, as well as they did all 4 breaks and a front end alignment. One of my calipers push piston wasn’t going back in, so they had to get a new one, but ordered it that day and came in 2! Very fast service and a great job too!

I came to this shop to have exhaust work done on my car. I dropped it off and the workers were absolutely helpful and made everything clear and understanding. The service did not take long at all and we agreed upon a great price as well. I would highly recommend this location !

This shop and all employees were AMAZING! Their quality and great customer service has guaranteed my business in the future! I had recently got some “custom” exhaust work at another muffler shop in Bolingbrook But was a little upset due to leaks and the welds look like a 15yr old did them. I did some research and found Jose on the FB market, he responded quickly and got my car in and out!

Definitely recommend to anyone in the area!!

Such a nice shop with a great, honest and polite team. This was my first time at a shop, my family has always taken care of my car needs. Jose was great over the phone and made me feel welcome once I was there. I called several local shops and they had the best prices by far. I will gladly recommend them to anyone I know and I will 100% be a returning customer for when my VW acts up again. Lol Thanks again guys. Glad I found this spot.

Took my Charger here to get a muffler issue fixed. Took the car to get a custom exhaust at Oxbo and they installed my mufflers backwards and tried to justify as to why they did that instead of fixing it. Didn’t argue and decided to take my Charger to Precision Diagnostics and they did a way better job right off the bat! Definitely bringing any of my cars to Precision, service was amazing, quality work, and honest people. Definitely come here for any exhaust work these guys are good at what they do.
