I purchased a pre-owned vehicle from Mercedes in Ontario

Reviewed by Jennifer felix from Upland ca January 07, 2026

I purchased a pre-owned vehicle from Mercedes in Ontario on December 11th. Initially, the staff were friendly and welcoming, which was promising. However, as time went on, I felt that the service did not meet my expectations. There were several minor issues that could have been addressed initially, but I had to return multiple times for follow-ups. It felt like there was a lack of attention to detail, and at times, it seemed the dealership’s focus was more on newer vehicles. I’m not sure if this difference in treatment was due to the fact that I bought a pre-owned car, but it definitely contributed to my frustration. I’m pretty sure I’m not the only one who gets a pre-owned vehicle, so that shouldn’t be a problem, but that’s how I felt in my personal experience. Now, as of January 6th, I’ve barely received the help I need. In fact, I was the one who had to reach out repeatedly, and the only other contact I received was from A.B. on December 20th, who left a voicemail. I tried to return the call, but no one followed up after that. This ongoing lack of support, especially during the holidays, has been frustrating. Well over all , while the initial experience was promising, the ongoing issues and lack of support have been disappointing. I hope Mercedes can improve their customer service in the future, even if my review might not significantly impact them given their national ranking.
