10 STARS Update:…read moreJune 17, 2026 I came here for oil change and mentioned some noise my husband was hearing. After thoroughly inspection the technician named Adrian stated that he will need to replaced the strut due to leakage. That being said, they provided a courtesy vehicle, allowing us to carry on with our day at no extra charge, which made things much easier for us. Whoever completed all the work on the vehicle, did an amazing job. The service at Karl Knauz is truly impeccable. From the moment you arrive, you're treated with professionalism, transparency, and genuine care. Kristy from service department is knowledgeable, attentive, and takes the time to explain everything clearly, making the entire experience seamless and stress-free. It's rare to find this level of service and attention to detail...exactly what you expect from the BMW brand. Highly recommend.

This establishment is highly reputable. (And trust me, I've been burned by dealerships in the past) My most recent experience was earlier this week. I purchased my new Jeep Grand Cherokee from this place. Our sales representative, Keyon, was top notch. Very personable, knowledgeable and most importantly, honest. The dealership manager, Adam, was a no b.s. type of guy (which I personally appreciate). Gary, the finance manager, was the same way - no nonsense, no over promising, just said it like it is. I highly recommend Fields CDJR of Glenview for anyone's next vehicle purchase.

So they're not looking to take your money; they want you to get the work done right! I've seen them handle difficult customers with calmness and respect. But their values are so humane too, which goes above and beyond any mechanic, much less any vendor. They hire special needs adults and do on the job training with patience, repetitiveness, and care. They are LGBTQ+ friendly and safe. I hope the best for this company and its employees, I hope the values never change. Good honest work with good honest people. A company that lives by their name: "Heart."

Very disappointed…read more.... When this auto shop first opened in Northbrook years ago, I was very excited because I thought "yay...I don't have to take my car to my dealership anymore" since I felt I was always overcharged for their parts and services". Heart was a little bit cheaper than my dealership so I was happy to give them my business. The front desk people were always friendly over the phone and in person and they were never pushy. My issue with them is regarding their honesty. I urgently needed a new car battery 3 years ago (2023). I called them on a Friday afternoon to check if they had a car battery for my particular make/model/year in stock. I was told they had it in stock and to bring in my car first thing Saturday morning. I was able to drive my car to their shop the next morning and the store manager at the time made sure that I got a new battery right then and there. He even called me the next day to make sure my battery was working fine. WOW! I was truly amazed by this high level of customer service. I've never had anyone from my dealership call me to check in. So over the next few years, I kept going to Heart for other services and was a very satisfied customer until today (Sept 2026). We needed to replace our car battery today since it was leaking and my husband decided to replace it himself. We went to Costco to purchase the new battery and bring in the old battery (for disposal) and what did we notice today? Heart installed the WRONG size car battery in my car 3 years ago!!!!!!! The Costco employee at the tire center was like "Is this the car battery that was in your car?" due to the obvious size difference between the battery we were going to buy at Costco and the one installed at Heart! Seriously? Not sure if the wrong size affected my car since it was jiggling under the hood all this time! Yes, my car drove fine with the wrong size battery all this time, but they installed the wrong size! The casing for the battery was TOO SMALL!!! They probably don't expect most customers to go under their hood and inspect or change the battery themselves so they probably didn't think we would notice the size difference! VERY DISAPPOINTED! They could have mentioned to me that the car battery they installed was a little bit smaller in size but not to worry since it wouldn't affect my car. A heads up about this would've been nice. But nope....no mention at all! They lost our business. We will never go to them again for any service!
