Excellent service. Friendly communication. No upsell. Showed up for oil change and after asking eta for completion they said 40minutes. I walked my dog in the neighborhood & received a phone call at 39 minutes 59 seconds. Wow on point, impressed. Bought the booklet of deals program they offer, essentially saving $$$ if you do repeat business there. We signed up & look forward to more services, A+ read more

Let me start off by saying that I have been in the industry for a couple years, and have been an at-home mechanic for a decade. Suffice it to say, when I tell you Deihl Auto Repair has been one of, if not the most pleasant car repair experiences I have had, I say it with some authority. Diehl, and specifically Kurt, have been amazingly helpful, kind, and respectful throughout. They did an oil change and PPI on a car of mine. The price was extremely competitive, and their work was spot on. If you are in the area, go to them without a doubt. read more

I recently needed new brake pads and rotors and the job was completed as per their estimate. I love it when great service is consistently practiced! I even lucked out with the timing because i was able to use a 20% off labor cpn! It's totally worth signing up for coupons with them! Their customer service has been tip top in my experience with them over the last 3 years. read more

I have used Diehl Auto for years. Recently I took my truck in for what I hoped was a simple repair but it was not. Greg took his time to explain the problem, the pros and cons to my repair options along with costs. He was very friendly and patient as I decided what action to take. I believe they are an honest auto repair shop and would highly recommend them! read more

Each time I have had a car serviced, they've been able to come through and help me out. Friendly, knowledgeable and good at what they do. What you want when you need car help. read more

STAY AWAY!!! They either have no idea what they're doing or just bs their way thru when busy. Went in for a pre purchase inspection for a car I'm selling. Straight up just told my customer not to buy the car half way thru the inspection due to a severe "coolant leak" I was confused so I went and checked it myself in their parking lot. Turns out it was water from the ac condensation. Coolant reservoir was completely full and red in color. I highly question the staff's intelligence if the mechanics doesn't know the difference between coolant and water. WASTE OF TIME AND MONEY! read more

Terry was the only shop in the area that would squeeze me in without an appointment. I had driven to St. Joseph from Chicago suburbs when my engine overheat light came on. I needed a repair to be able to go home. Terry fixed the problem and charged a very fair price! Would definitely recommend! read more

This business is great. Car repairs everywhere are expensive, but here you feel like they are 100% honest in their answers, and not trying to upsell you. I listened to them talk to several customers while I waited for my car, and every person was treated the same, honestly and fairly. Their website has some coupons that they will apply to your repair, so check! read more

Brought my daughter's Buick in for an inspection before she drove to Texas for school and was very happy with the service. Her brakes needed replacing and the work was done that same day.

I have been going to Diehl Auto Repair for the last couple of years to both of their convenient locations in Downers Grove. I've never had repair work done from either of these locations while under previous ownership. I can tell you from the outside in and the inside out these guys are serious They give you better than dealer service at the highest level and provide you with an analysis before any work is done to your vehicle. Honesty and transparency is the policy and it's so refreshing to have an honest mechanic on my side I will never bring my vehicles Anywhere but DIEHL Auto Repair! Great job guys as always! read more

Found Diehl on Google in 2018 and have been a customer ever since. Always upfront and honest and they don't try to upsell you. Keep up the great work Diehl! read more

The best repair shop you can find! They are friendly and do great work! Don't go anywhere else! Jim June 2023 read more

First time I went for a flat tire they fixed it and it was flat within days again, so this means they did not do the job properly. Second time they fixed the brake master cylinder of my Lexus but it did not resolve the issue so they then changed the Calipers which fixed so this means they don't have a good diagnosis and its just trial and error shop, I had to pay for both fixes when it was just the Caliper fix that was needed. I recommend stay away from this Shop. It was my mistake I went to them second time seeing all 5 star reviews but now I know. read more

The guys here are all very friendly and knowledgeable! I am so glad I found Diehl Auto Repair! I wanted to find a place to take my car and feel like I could trust what they told me.

Gil and the crew at Diehl Auto are great. Honest and thorough. They take care of all our cars. Highly recommend.

Took my truck to Downers Grove Diehl Auto. Great service and honest recommendations on what needed to be fixed and what could wait. They installed 4 new tires/rims and changed the oil and brakes. Will be going back as Brad and Rick were both great to work with. Well done guys!! -Tim read more

I went a ways to this business because it received top reviews from a number of people on nextdoor.com, I am new to the area, and my check engine light was on. They changed my oil and looked everything over, no problem. A week or two later, I noticed oil leaking at my parking spot, so I took it back. The mechanic showed me, under the car, how the oil pan must have scraped over something (like a high curb) and the valve had been pushed and scraped. For free, he replaced it and sent me on my way, a happy camper! I will make the trip back to them! read more

This place is a good, honest mechanic shop. They lay out all the possibilities for my car's challenges and empower me to make the best decision. The folks are nice as well. The rates are reasonable for young professionals. read more

I am new to the area and found Diehl Auto Repair. After a couple of service visits on different cars, I can say that they perform quality work at fair prices. AJ and Greg are great to work with and provide you with necessary updates while your is being worked on. I strongly recommend Diehl Auto Repair for your car servicing and repair needs. read more

I started bringing both my family's cars here instead of their respective dealerships, not just for oil changes, but also for suspension and air conditioning work. I appreciate their commitment to quality and warranty of their parts and labor. I don't see a reason to go anywhere else. read more

Great people at Diehl Auto! We have been taking our cars to them for years and have never been disappointed. Their service is above and beyond. Highly recommend! Thanks, Diehl Auto. read more

Great place to work with. They gave me a fair price on my original brake estimate and then a great price on new tires I also knew I needed soon. Will be going here from now on! read more

My car has needed new brakes for a while, but I'd been putting off taking the car anywhere because I wasn't sure of the best place to take it. Thankfully I found Diehl Auto Repair. I scheduled an appointment and the day of the appointment dropped off the car right when they opened. Owner and front desk Superman AJ said he would call as soon as he knew details on what was needed (brake pads, rotors, calipers, etc.). He called within an hour of my drop off and explained the situation. I let him know what I wanted completed and what I needed to wait on, and he was very professional in not being pushy about anything that was not an immediately-needed repair. He was also very gracious in not making me feel embarrassed about how desperately my car needed new brakes! When I arrived to pick up the car just before they closed, Phil provided my paper statement showing what I'd been charged, the repairs done, and the recommendations for near future. To top it off, they had a Yelp coupon! I have found my go-to repair shop. As someone who tends to keep cars until they're ready for that big junkyard in the sky, they will be getting plenty of business from me. Thanks guys!! read more

Awesome awesome service! Thorough and helpful. Had a bad experience at a Buick dealership and they stepped in and solved my problems in a day. Will be coming here from now on. Skip the dealer and come here! read more

We bring both our cars to AJ @ Diehl Auto and we have been extremely happy with every oil change, repair, and recommendation. They do excellent work, don't take short cuts, and charge a fair price! AJ and Greg do a great job explaining what needs to be fixed and why. I trust AJ through and through and would recommend him to all my friends and family. read more

No work done other than inspecting my van. I was sure I needed an alignment and maybe front end suspension after buying 4 new tires. They took their time, inspected everything and though my alignment was barely off, it was still within specifications, and suspension was all good. Basically they easily could have made a few hundred dollars or more but told me to wait a bit, no worries and it was likely my tires were simply bad tires! What great business ethics! I applaud AJ and crew, you just got a future repeat customer! read more

Loved these guys. They were great. They were honest and upfront about the repairs that were required verses recommended. Pricing was fair and I'd take my car there again. read more

Reliable and very honest, which is hard to find nowadays. I'm glad I found this place. Highly recommend!

Wonderful and honest auto repair shop! Brought my car in and feared for the worst, but diehl auto was straight forward and didn't try to upsell or get me to fix other unnecessary things for my car. Told me what was going on and got it fixed that day. Appreciate an auto shop near by that I can trust! Thanks Diehl Auto! read more

Very thorough and do a great job. Very detailed and make sure I understand what was done and/or needs to be done. I highly recommend Diehl for all your automotive needs. read more

It may have been because of the cold weather, but I stop by because I couldn't get my gas door latch open. I pulled up walked in., asked for help, and someone came right outside with me, and help get my gas latch open. I definitely will be going back for more care repair needs, and will be recommending them to family, and friends in the area. read more

I took my 2005 Honda in to replace my front brakes because they seemed a bit spongy and I hadn't had them replaced in a few years. Another well known repair shop told me I needed them replaced. I got a quote from Diehl which was lower than the other repair shop and took my car there. AJ called me an hour later and said the pads and rotors were fine and could last maybe another 10,000 miles. All I needed was a cleaning and adjustment. They work great now. They are very honest and knowledgeable I will be taking my cars there in the future. Would highly recommend them! read more

I am blown away by this repair shop. I live right by the Lisle location, but it is very busy (and I'm not surprised why!), so I have been going to the new Downers Grove location to service my car. Rick and Luis are both amazing!!! Very personable, knowledgeable, and professional. I'm not very knowledgeable about cars, but no question is a silly question to them. They are very honest and their prices are reasonable. My fiancé and I refuse to go anywhere else for our oil changes or any other repair needs for our vehicles. Cannot recommend them enough! read more

These guys are good. In my experience, they diagnose the problem correctly the first time and the repair bill will be reasonable. I hate what it costs to maintain cars on things that I cannot fix myself (which is anything more complicated than adding oil). But everything is documented (part price, labor time, ancillary parts) so I never feel like I am getting screwed. I have taken my cars there numerous times and have never been sorry. Highly recommended! read more

Love them, they do a great job, give you tons of info, save you money with good advice. What more is there to say? They are everything you hope for in your neighborhood mechanic. read more

Diehl took car of my Yukon Denali and my Sierra Denali. Great service, support, safe, clean, not going back to the dealership. They were more professional I had a bad experience with my dealership during there crazy times and they didn't do a good job read more

Brought in my Hyundai Tucson for an oil change(~$57 for full synthetic). Everyone is super friendly, Greg went over everything they did with my car and some concerns they had and made sure I understood before leaving. When I need work done I will be bringing my car back! Definitely recommend. read more
