Ken Sargent GMC Buick

Not what it used to be, Took my truck in for warranty work, a coolant issue, and to get some fluids changed, they had a promo going for a free inspection, ok cool, not gonna turn that down, called me in the middle of the day to give an update, told me the cabin air filter needed to be changed, declined as I do both my vehicles at the same time every year, didn’t have any more info about the coolant low message coming on. Fast forward to picking up the truck and they billed me for cabin air filter and labour to replace even though I declined and wouldn’t take the labour portion off the invoice. I was charged an hour of labour for the tech to “check” the entire cooling system for leaks even though they were told there is no leaks and the “low coolant level” message coming on in the cluster was the only issue. Tech didn’t find anything wrong, and noted on the invoice that “when the truck is running hot the sensors will sometimes read as low due to the heat transfer from the fluid”… on a cooling system that stays hot while truck is running. Not even 15 minutes after I left the dealer the low coolant message came on again, checked fluid when I parked and everything was fine. Checked over the rest of the truck and found the tech had most likely dropped the old cabin air filter on my Center console which dropped onto my passenger seat and left dust all over my Center console and passenger seat. If this is the level of service Ken Sargent has to offer I’ll gladly take my vehicles to Wheaton going forward.

René Gendreau at Ken Sargent GMC was a wonderful salesman. He was very professional, patient, and provided amazing customer service throughout the whole experience. Even though we didn’t end up getting a vehicle from the dealership, René still treated us with kindness and respect the entire time. If you’re looking for a car and want someone honest and easy to work with, I definitely recommend checking him out!

Amazing service from start to finish. We purchased from out of town. Darren was very helpful and accommodating, and checked in after the vehicle was home with us. Suzi is also the best! Combined, they made a tricky situation of being 6 hours away the easiest, smoothest transaction. I couldn’t recommend this dealership more!

This review is solely based on my experience with the service department. Our experience with sales and finance has always been exceptional- kudos to Shannon, Nick, and Al. We have always ran GMC for personal and fleet. Our latest interaction with service was beyond unacceptable and had us wanting to follow many others lead- to use only Wheaton for any service (and sales) moving forward. A particular individual on the service side seemed to take a report of vehicle issues personally and was hostile on both the telephone and in person throughout the service. This vehicle has been a headache since purchase, An Ultimate Yukon purchased last year sat in the shop 30+ days at purchase bc of “suspension” issues. We drove it off the lot and the suspension failed at 600km. The running boards throw consistent errors. We were told to just shut them off in the winter- kind of defeats the intention of a kid hauler when you have to boost them up to even get in… but we did as instructed. They were Turned on intermittently when hand washed etc. The errors won’t stop and they often don’t work or get stuck down. At this latest service we were told we had them “shut off too long” and that next time we will be charged for this? Told that The issue was only that they needed reprogramming and we were at fault for shutting them off. Hilariously we left to only get an error regarding the running boards that same day, which is yet to be dealt with bc we want to avoid hostility from the service side. We were big Ken Sargent fans but are disappointed and reevaluating where to take our business solely from our service experience.

Went to Ken Sergant GMC and found a vehicle I liked - dealt with salesman Trevor Ginther. He made the experience of buying a vehicle awesome, there was no hassle and no pressure. I would 10/10 recommend going to Trevor if you ever want to buy a vehicle, as he was the best salesman I have ever dealt with.
