Mercedes-Benz Rive-Sud

Stay away from Mercedes! Bought a 2026 AMG GLC43 Nov 2025 and it has been in repair from Jan@Apr partial engine replacement. Had the car for just a week and the problem persist. BMW is the wiser choice; I had 5 brand new ones in the last 9 years and not a single complaint. As I am writing this message my « expensive » car isn’t providing my any thrill but rather anxiety and deep regrets. A clear plan to ensure a proper reassuring customer experience is still nowhere to be found by Mercedes Canada. Nothing prestigious and exciting about doing business with Mercedes. My car is meeting the definition of «lemon » by law.

I am writing to formally file a complaint regarding the unacceptable service experience I have had with your dealership, Mercedes-Benz Rive-Sud, specifically involving service advisor Arron (Zhemin) Xu. My vehicle has been at the dealership since approximately mid-April 2026, and as of May 25, 2026, the situation remains unresolved with very little meaningful progress. I would like to raise the following concerns: Refusal and unwillingness to properly handle insurance-related repairs When the case was first opened, Mr. Xu stated that we could move the vehicle to another Mercedes-Benz dealership because they were not willing to prioritize or properly handle repairs processed through an insurance company. The impression given was that insurance-approved repairs were not financially attractive to the dealership, and therefore our vehicle was not being treated seriously. This is extremely disappointing and unprofessional for a Mercedes-Benz authorized dealership. Vehicle left contaminated and unrepaired for over a month The vehicle has remained at the dealership from around April 10 until May 25 without proper cleaning or full repair assessment. There was food contamination in the vehicle which resulted in rodent activity and possible contamination inside the car. Despite the health and sanitation concerns, the dealership did not clean or remediate the vehicle during this entire period. Furthermore, the front section of the vehicle has reportedly not even been fully opened or inspected for a proper repair evaluation. We were only informed that a “main cable” would need to be ordered from Germany with an estimated delay of up to three months. This level of inactivity over such a long period is unacceptable. Extremely poor attitude and lack of customer care When I asked why the contaminated vehicle had still not been cleaned, Mr. Xu stated that he needed approval from his manager and that there were currently no technicians available. He then suggested that he could simply give me the keys so that I could clean the vehicle myself. I responded by asking why the dealership staff could not handle the cleaning instead. Following this, Mr. Xu called his manager, Gemi, and misrepresented the situation by stating that the customer was requesting that Arron Xu personally clean the vehicle, which was not what I had said. My point was simply that the dealership should take responsibility for properly handling and cleaning a contaminated vehicle left in their care for over a month. Throughout the interaction, his attitude was arrogant, dismissive, and entirely lacking in customer service professionalism. At no point did he appear interested in helping resolve the issue appropriately.

Olivier assisted us with the best service, we were looking for a new car and he took the time to give us all the info we needed and didnt hesitate to offer us the best pricing. He made us feel very welcome and our experience was very good due to his positive attitude!!

Maintenance service is horrible. I like the car, so I decided to change dealership and would definitely not recommend MB Rive Sud. I called a couple of times, no one ever picks up the phone during business hours. It feels like calling Bell! I left messages more than once and never got a call back. I even tried through the chat on the website (who is great for sales by the way, but for maintenance, they obviously don't care), they take your info and tell you they will reach out. Again, I waited a few days and haven't heard anything. Very frustrating, I had 2-3 maintenance issues since I bought the car and maintenance service is not worthy of the brand in this dealership. Changed dealership and I had a good customer experience with Silver Star in Montreal (someone actually picked up the phone, communicated with me through texts and the appointment was booked in a matter of minutes). Looking for a Mercedes Benz? Avoid MB Rive Sud, because after sale service is crappy. (I got to say that the purchase experience was good though.)

Excellent service every time I bring my car in to Mercedes-Benz Rive-Sud. The team is always professional, welcoming, and reliable — special thanks to Tanya for her outstanding help and customer service!
