Mercedes-Benz of Naperville

I brought my 2019 GLC 300 to Mercedes-Benz of Naperville on May 16, 2025, for routine service. I was quoted $3,199.24, but was only given a vague handwritten estimate with no proper itemized breakdown. As s on May 16, 2025, for routine service. I was quoted $3,199.24, but was only given a vague handwritten estimate with no proper itemized breakdown. As someone who doesn’t know much about cars, I trusted Mercedes-Benz because I expected professionalism and transparency. Instead, I was met with the opposite. My advisor, Nick, told me these were essential services needed between 55,000–60,000 miles. He said they were manufacturer-recommended for my mileage, so I believed him. Later, after asking several times, they finally gave me an itemized breakdown and that’s when I realized how inflated some of the charges were: $729.95 for spark plug labor $266 for a brake fluid flush labor Over $1,000 for a transmission service When I questioned why I was never shown an itemized invoice beforehand — and only received one after repeatedly asking — they completely shut down the conversation. When I brought up the lack of transparency, the only responses I got from the service manager, Mike, were things like, “No one forced you,” and, “That’s why you learn to don’t sign next time,” among other rude remarks. Completely unprofessional. I wasn’t even notified when my car was ready. I waited all weekend, only to find out they had texted a relative out of state by mistake. On the pickup day, I called several times during business hours asking for a status update but no one pick up. The shop closes at 4 PM, so I called again and finally someone picked up but all she said was, “Sorry, service is closed. You just can’t get your car till Monday.” When I asked why no one contacted me especially after I had specifically asked to be called or texted when the car was ready — she said, “I don’t know.” I asked to speak to the manager or my advisor, and she said, “Sorry, nobody is here, they’re all off. There’s nothing I can do.” No apology. No accountability. I was left without a vehicle for the entire weekend. And then there’s the key battery issue that I found out later: I was charged for a key battery replacement, but they installed the wrong battery, a CR2032 instead of the correct CR2025. It’s thicker, and it looks like they forced it shut. The key is now jammed and unusable. I’ve attached a photo. This is ridiculous. They claim these prices reflect work by licensed professionals, yet they couldn't even get a basic key battery right. As someone from a Mercedes-owning family, I expected much better from an official dealership. We won’t be coming back. I’m taking my time to write a review like this for the first time because I genuinely hope others will take notice. More

I’ve been going to Mercedes Benz of Naperville for some time with my previous lease being over a year ago. A few days ago I returned to look for some more cars and sales representative Nick provided the mo time with my previous lease being over a year ago. A few days ago I returned to look for some more cars and sales representative Nick provided the most pathetic service I’ve ever encountered. He was firstly extremely mad that I wasn’t transparent with him about going to BMW and getting quotes, which he stated “I’ve been in the business so long that I already knew”. Not sure how long he’s been in the business but I never went to BMW to begin with! Secondly we weren’t able to reach numbers that worked well and we told him repeatedly that we appreciated his time and efforts. He texted me a few days later asking if I was interested in moving further with any of his cars and I told him I had purchased one from Mercedes Benz of Chicago. To which he had the audacity to send me a message to let me know I had wasted his time! This is the industry Nick, maybe you haven’t been in it long enough. More
