They helped me when I was trouble, and I know nothing about the area, so I definitely recommend them to anyone that needs sweet helping guys!

Very helpful and knowledgeable. Have a 2004 Escape 342000 miles leaking antifreeze. They came over and inspected the vehicle. Water Pump leaking but looked at the whole vehicle and its trouble spots to give me an honest mechanical opinion if worth fixing. Good mechanically and frame wise. Got it fixed. Other parts in the repair were ready to fail so fixed them. Very Happy. I feel I can trust them.

5 stars isn't enough for these guys! They deserve ALL of them. I cannot thank them enough for their speedy service in repairing my truck and getting me back on the road. Or their friendly and kind attitude towards helping out a fellow human being and not treating me like im inferior because I am not a mechanic who works in their shop like so many other places do. Complete night and day difference in the best way possible when dealing with Jay & J's versus a big named competitor. Driving on 41 north around 12:30 p.m. near west bend my trucks rear end starts to violently shake. I may not be a certified mechanic, but I know my way around a vehicle and am very familiar with my truck. No lights on the dash, no smoke anywhere, and without getting under the truck to look, I figured it was a U-joint. While limping 5 mph on the freeway to the next exit, I did a quick Google search of the closest mechanic and would have settled on the first available place to get me in ASAP. I am so glad the first place to pop up on Google's results were "too busy" because next on the list was Jay & J's. They answered the phone quickly, was friendly and encouraging and most importantly, they made time for me and my emergency. I get to their shop and before I knew it my truck was fixed and I was on the road again. I was allowed to look at what they were doing to my truck, see what they were seeing, and even got a quick diagnosis of other possible issues. They were able to get the part I needed INSTANTLY, and had my truck fixed and out the door by 2:30. I dont live in the area and hopefully wont ever need emergency help like I did. But I pray that if my truck decides to break down again like it did, im near Jay & J's auto!!! Cannot say it enough and would HIGHLY recommend them!

I took my car in this place and now it runs better than it did when it was brand new. I would recommend this place to anyone that wants their car done right

Jay did a great job getting me in quickly. The work required was quoted and done at a great price! My car hasn't run this smoothly since I bought it, thanks guys! ?

Working with them for a few years now. Don't want to take my car anywhere else. Good prices, amazing work. Treats my car like there kids will be in it. Gets me back on the road as fast as possible. Could not ask for more.

I took my 2020 Equinox in for a diagnostic and some brake work and had a great experience. I was in need of a repair quickly as I use my vehicle for work and wasn't able to get into my normal shop for over two weeks. Jay & J got me in the same day and had the diagnostic completed and brake issue identified within a few minutes. The repairs were reasonably priced and completed within a day. The day my car was in the shop I drove over a screw and asked him to take care of it when I picked up my other vehicle and not only did he take care of it but refused to charge me. I'll no doubt return for all future vehicle maintenance and repairs.

Best. Most knowledgeable mechanic in the area that charges only for what you need. Highly recommend. Wish I could give higher than a 5 star!!

Wonderful work, was able to fit me in last minute on their schedule, very professional. They were able to answer any questions or future concerns about my 2018 Lexus es 350. Thank you again so much Jay!

I appreciate your help! I ended up getting a hole in my tire on the highway. Not wanting to run on the spare for a long distance I called Jay & J's who after a short friendly conversation offered to plug the hole and get me back on my way as soon as possible. After a short detour and a quick plug install I was back on the road and on my way home. Thanks again!

On Thanksgiving morning my fiance and I ran over something that punctured our tire on the highway up north. As we slapped on a spare I called around to several auto shops in the Lomira area and everyone was understandably closes. But Jay answered the call and graciously offered to take a look at the tire, even though he technically wasn't open. We rolled up and he happily assessed the situation and was able to plug the puncture, put it back on the car, and save our Thanksgiving. He and his partner were friendly, professional, and knowledgeable. They helped us out in a tough spot on a very important day. Thank you so much!

I only had the opportunity to speak to the owner (I assume) over the phone after hitting a deer a long way from home. Based on how helpful and interested he was to talk to someone who has never (and likely will never due to distance) been/be a customer, I wouldn't hesitate to take my car to Jay & J's Auto if I lived anywhere in the area. Your time and expertise were greatly appreciated!

I had 2 punctures in my tire and he was able to fix it up super quick! Very friendly and knowledgeable! Great prices as well! Definitely would recommend and will return for anything else that might come up!

My company truck broke down just out of town. Within 10 or 15 minutes of my phone call they were there to help me get my truck started and I drove to the shop for them to replace an alternator. In a very short time, I was on my way. Very friendly, knowledgeable, professional. They turn a stressful situation into a manageable situation. HIGHLY recommend J&J.

Jay and Chris are friendly, knowledgeable mechanics. Reasonable prices and quick service. They take time to show and explain what is wrong and normally have a couple options for repair. My family loves using them for everything from total engine replacement to new batteries.

Failed to communicate, then called me a liar and swore at me when I took my business elsewhere. And I stated that I didn't do business with them because of the unprofessional treatment. Therefore, I wouldn't be on your records...

While we would have preferred not to have an encounter with these generous and caring people, they ensured that we were well taken care of. This is a great location to take a pit stop if you happen to end up in a predicament like my buddy and I did. Thank you for the service, as we could not have overheated in a better place.

This guy Jay saved me and my buddy when our box truck broke down on Highway 28, he gave us amazing and kind service. After we got the truck to his shop he switched out our water pump and did a diagnostic of the vehicle within our time frame of only a few days and we were right back on the road, with out a single issue on our 100+ mile drive home. Great communication, amazing value, and all around outstanding quality. I would highly recommend Jay and Js to anyone who is looking for service that is straight forward no bs, and done right the 1st time at a very reasonable price.

They went out of their way to take care of the repair. I would recommend them to anyone. They are very fair with cost, more reasonable than anyone I've dealt with. These guys really know their stuff.

I had used Jay’s for and emergency transmission leak. The problem was quickly found and repaired within 2 hours. The cost was fair also. Because if this I used them for replacement of front struts. I had an estimate done elsewhere and Jay’s estimate was very much lower and the work was done quickly and expertly. I am very satisfied with their work and would highly recommend them.

Couldn't ask for a better mechanic. Honest, affordable, and gets the job done right no matter what it takes. Brought our 2001 Ford Taurus in for what was originally a bad alternator but ended up being an absolute nightmare. He did absolutely everything he could to get it fixed for us even though it was definitely driving him nuts, lol. ?

Jay was great!!! Honest and precise. Very fair pricing!!!!Explained things how I could understand. I highly recommend them for all you Auto needs.

Jay did my husband's tires in a very timely manor. At a very reasonable price. Will definitely be taking all my vehicles to him. Highly recommend

I called them to see if they were able to get a stripped lug but off. He said yes bring it down. He worked on it for a few hours, broke tools trying to get the lug nut off. He was finally able to get it off. I asked him what I owed him, he said 20-30 bucks. He was a life saver and very cheap price. I will take all my car repairs to him. Very friendly and knowledgeable.

Took my car to him for engine. Paid him 2500 to get it fixed. The night I picked it up check engine light on took it back 5 times to fix never touched my car. Do not trust this mechanic.
