134 Ontario GMC Dealers

Just purchased a 2023 GMC Sierra 1500 Denali Ultimate - Brad

Just purchased a 2023 GMC Sierra 1500 Denali Ultimate from Reid Bros Motor Sales and they were fantastic to deal with. Jim Kwiatkowski was an absolute pleasure to deal with, and helped me out so much! Being from the Toronto area it was the only dealership in Ontario that had this truck available and the Reid Bros staff made the 5 1/2 hour from home purchase smooth. Thanks again Reid Bros, you are a Wonderful Dealership, just wish I could get my service from you but its a bit of a hike from home. Thanks again, and highly recommend this truck!!

We recently visited Seaway GM from 2 hours away to look - Kayla

We recently visited Seaway GM from 2 hours away to look at a used truck. We dealt with Derek and he made this experience great. We had a bad experience at another dealership and he made sure it was not the case with Seaway GM. We traded in an SUV and both the trade and purchase went extremely smoothly and quickly. We also dealt with Scott to finalize the purchase and he was also great, explained everything in full detail. I would highly recommend dealing with Derek at Seaway GM for your next purchase.

Only got one star because there wasn’t a zero. - Roxanne

Only got one star because there wasn’t a zero. Hal Wrights dealership is by far one of the least professional local businesses we have ever dealt with. After far to many negative experiences after purchasing our first new vehicle, and returning for recalls with them I have observed very low morale amongst employees in service. The result of this has been little to no positive customer care and service. There is no accountability for thier mistakes. The is arrogant behaviour in management positions. Many years in professional positions has taught me that these behaviours come from the top. Their lack of integrity and values goes against the man who actually built this business. Hal Wright. And perhaps this is the difference in building a business or having it built for you. My hope is that the current owner will take these many poor reviews seriously. Be aware of the many many local GM owners who go out of town for purchases and service. AND make the changes that need to happen to make this an establishment they can be proud of.

Service Advisor was very professional and was very good - Bruce Culp

Service Advisor was very professional and was very good about explaining items that may require attention on future visit.

Haven’t learned how to properly repair a tire, still using plugs instead of patching properly

Not encouraged to buy - susan

Viewed a used car, loved it and wanted to purchase it. However the price on the Internet was changed by $3,700 more when I came back after a lunch break. Salesman, said this is now not in your price range, so I will contact you when other cars come in. No interest in my upping my budget. I would have bought this car, but from my perspective my purchase was not the one wanted by this dealership. I had money to give them today but Mike Fair clearly wanted someone else's money. I will never return to this dealership.

Worst experience I have ever had,never be back and will - lbbancroft

Worst experience I have ever had,never be back and will tell others all about, they could have made it right but chose the excuse after excuse method, please think twice before going there, the main thing is the car was fixxed by a honest shop and I saved about 1000$ for repairs not needed just a simple tightenjng of a gear clamp on the turbo, which they installed, The worst part is they must think a lot of people do not know what they are doing, I was very rude in the last conversation I had with Steven, just want them to know that its not right what goes on there. I wont be back, word gets around, think twice people cause they will not back up there work or even work with you

Friendly place to do business. - Denis

Friendly place to do business. Best service department in Sudbury. Wood recommend to friends and family.

My first experience should have been a better situation - FSGale

My first experience should have been a better situation then it was. Both my father and older sister purchased brand new trucks from this dealership, and so I brought my business to the same sales person. They sold me a used Jeep Compass, low KMs. However, ever since I have been discovering one issue after another. 1) They did next to no maintenance on the vehicle, almost immediately I had to replace the sway bars on both sides, a constant annoying sound every time I hit a bump. 2) The brakes should have all been replaced before I purchased, clearly never touched by this dealership. Instead they gave me this vehicle with something clearly wrong as the brakes were grinding nasty grooves into the rotars; and 3) 8 months after purchase I find out that I would have to eat $17k in negative value to do a trade-in, as the dealership clearly charged me far too much for a vehicle that was not worth that value. Never go with these folks!

Brought car in for transmission stalling issues (car... - maureenm1964

Brought car in for transmission stalling issues (car wouldn't go over 3000RPM). Apparently, the "experienced mechanic" took the car out and found no issues. Diagnostics were run on car with no issues found. Four hours later after I made the call to see what was going on, I was told that the "knowledgeable" Supervisor said it was because the car mats were stuck under the gas pedal. (I always pull my car mats back in place before I get in). So for all this xx I had to pay $75 and the car is STILL doing the same thing that I brought it in for. Only bonus of the whole experience was Pat. Very friendly.

Ray Cullen has the best service department in all of - brian.courtney

Ray Cullen has the best service department in all of London. Every time I go there I am treated so well, their service is so efficient and very very timely. Your in and out so quickly with such very good quality of service. I have bought most of my cars at Ray Cullen and this dealership is the best by far. Thank you so much.

Service did an oil change that was not mention and want - Dunn

Service did an oil change that was not mention and want $322 as still have 4,000 km left and 2 months left. Was supposed to do just the recall that were required. There was no mention on the paperwork about service and should see it was not do for the truck. Now i have no truck because of their screw up. Screen shot shows no service was needed only recall stuff ......

The woman who took the information about my son’s tire mishap. Ignorant, rude and obtuse Stay away !!

I recently purchased a new Buick from Tailor and had an - KateNW

I recently purchased a new Buick from Tailor and had an exceptional experience. It was my first time buying a vehicle and I was by myself but all of the staff made me feel very comfortable. The turnover was very quick and on delivery day everything went very smoothly. All promises that were made were followed through. My mats weren't in but Parts called the next morning and delivered them to me in Belleville which was greatly appreciated. Looking forward to servicing my vehicle at McCurdy's.

I left a cruse Cruze for an Oli change and I was told - Ide Guimaraes

I left a cruse Cruze for an Oli change and I was told that drain plug was too tight and it could break when removed, I didn't given them the go ahead as it would cost me an oil pan replacement, took vehicle to an independent mechanic and I witnessed drain plug being removed wt no effort at all, actually the garage charged nothing for the service. It makes wonder what really happened, I am extremely unhappy and disappointed with the quality of the service rendered, I left the vehicle at Boyer for hours for a simple oil change and I wasted my time taking it somewhere else. I always trusted Boyer for my vehicle but now I have second thoughts about it and I want to hear back from Boyer about it.

attended an EV test drive event at the dealership and had - gtaelectrical

attended an EV test drive event at the dealership and had the opportunity to experience the 2025 Hummer EV firsthand. Sarah walked me through all the features in detail—she was incredibly knowledgeable and made the experience both informative and fun. The staff overall were very friendly and the atmosphere was welcoming from the moment I arrived. It’s clear they’re passionate about what they do and genuinely care about customer experience. Highly recommend checking them out

No one answering the phone in the service department - Unhappy Silverado Owner

No one answering the phone in the service department today (again). Drove in to have a flat tire repaired and have a few other things looked at. They could do the tire today I was told, but for the other items I would have to make an appointment for Monday. It's too bad you can't call and make appointments over the phone. The tire needed replacing and the quote for the tire (505) an TPMS sensor (115) seemed a bit steep. I asked if they could match Canadian tire's price (452 and 56). The service manager said yes, but I had to provide a current ad. I didn't have my laptop with me and couldn't find the tire on the phone, so he wouldn't discount them. I went to Canadian Tire to get a quote from them. They hand the parts in stock and technicians available. Getting everything looked after today and saving a bundle on the way. I'm not a big fan of Canadian Tire, but Myers service is far, far far worse.

I noticed somewhere that Hallman GMC in Hanover got a 4. - Albert

I noticed somewhere that Hallman GMC in Hanover got a 4.5 star rating. How anyone could give them a "less than 5" is beyond me. I've been going there for approx. 5 years and has had nothing but 5 star service. Somebody must have had a bad day (customer) Albert Hodder

**Warning** This dealership has NO - fraserf2009

**Warning** This dealership has NO regard for their customers. If you are not familiar with the parts return policy don't expect them to inform you at the time of point of sale what the return policy is. Apparently Dennis Searles feels that ever customer who purchases a part from them is in the industry and knows this information as I was told by the Parts Manager, even if you're a 17 year old boy. The part that he wanted to return was an electrical part that yes had been opened to ensure it was the correct part but was never installed, not that he didn't need the part but because he found the exact part on Amazon a lot cheaper. We also tried to have a conversation with Kevin Searles regarding this matter and was told "I'm not going to entertain this" and hung up on us. So word of advice, do yourself a favor and stay clear of Dennis Searles ... * A formal complaint has been filled with GMC Canada*

Very pleased with david roy and the people at quantrills - Roywoody88

Very pleased with david roy and the people at quantrills did a great job getting me into a new truck

These guys nearly blew my engine - Rick

I had purchased a car and brought it to them for a full checkup. two weeks later as i'm driving the engine coolant light comes on. I had no leaks and the radiator was only half full. No to mention parts they changed that my mechanic told me would have cost me half the price. Total neglect in their part. I wouldn't bring a wheelbarrow there for service. I bet Canadian Tire has better mechanics. No more dealerships for me. Find a good mechanic and save lots of money!!!

Exceptional knowledge, persistance and customer service - Peter maher

After discouraging performances with dealers in 2 counties I made a point to travel extra distance while in Sarnia to try these guys out. My daughter referred me and she travels from Midland to Wallaceburg to do so. We are from Wiarton , neither of us,around the corner. From the time we walked up to the service desk to the time we drove away, the whole interaction was professional, personable, friendly and knowledgeable. The communication during the frustrating problem my vehicle presented was outstanding. As a customer without history in the dealership, I felt important and that my business was valued regardless of the fact my truck was a 2008. Some corrective work to shoddy work by another dealership will be done later and we will drive the 3 1/2 hours because they are worth it! When we buy another vehicle, the same will apply. Thanks Brian to you and your gang. It doesn't't get any better. If Riverview were to expand operations I would suggest they become a GM dealer training centre... Peter and Lisa Maher Wiarton

Could not have been happier dealing with them. Caesar made my experience a very pleasant one, from the first time he met me on the lot till even after I took delivery of my 2021 Sierra Denali. I have never been treated so special in a dealership like he did. Thanks Caesar, Dustin and Phil for an amazing experience.
