Spring Slap in rear of vehicle - stromdwayne

Service is terrible and they refuse to warranty my trucks that they installed a lift in, they also dented my truck several times in one visit. they expect me to live with a spring slap clunk in the rear of the truck even tough it is new, and should have warranty. They originally told me that they sell several trucks with lifts and that it will not effect the warranty but not they refuse to fix the clunk now and say they are not responsible to do anything for me!!!

On our way to Kincardine, we had car problems on a Friday - barblawrence10

On our way to Kincardine, we had car problems on a Friday at 12pm. They could not promise to look at our vehicle but would try. It was a very upsetting day but the shop managed to look at our car and fix it. We ended up killing time by test driving a Trax. Then we spent time with Bernie on what it would take to get a new one. I told him we were honorable people and if decided to buy we would make the 2 hour drive to buy from them since they helped us. We are in the process of buying from them. A great team there. Thank you.

If you do loads of surfing on Reddit, you should have - Charles Wyne

If you do loads of surfing on Reddit, you should have come across thecybergoat@techie.com credit score repair experts. I've seen a lot of people posting their credit reports and claiming thecybergoat repair hackers have had them fixed. I emailed them and had me boosted. Experian was 422 and now is 724. They're a highly and positively regarded hacker team!!

Seasonal vehicle maintenance - Goldengal

The staff is very nice and accommodating. They gave my wife and I a ride home, while the vehicle was being serviced. They also called us promptly after our vehicle was ready and arranged for return travel back to the dealership.

Money grab and a pompous staff for sure as stated in the - jdenommee

Money grab and a pompous staff for sure as stated in the comments. If you are not knowledgeable about vehicles they will take advantage. This dealership preys on people who don't know better and are trusting them to be honest. This dealership had me leaving and returning with new problems each time I came in for service or an oil change for the last 4 years. Coincidence or bad luck until the last 2 oil changes were both leaking due to sloppy work . The last oil change was performed 1 day before leaving on a trip to northern Ontario leaving me stranded in Sturgeon Falls ON - no oil in vehicle. Vehicle had to be towed from Sturgeon Falls to Sudbury where it was discovered that the oil filter was cracked - either already damaged or cracked while changing the filter. Either way this was the second time and difficult to believe it was a one off being the second time in a row. John Bear did not want to be accountable and laid blame on GM for defective filter. John Bear also insisted that the engine light that remains on since the oil leak was completely unrelated to the drive from Hamilton to Sturgeon Falls without any oil left in my vehicle ??? I now realize that much of the service that I had done on the vehicle was likely unnecessary - such as spending over $1200 including a discount to have all the lines changed under vehicle 3 months earlier which did not resolve clunking issue. Clucking was in fact due to loose bolts underneath after returning with the same complaint - they didn't see this during the inspection and decided the line needed replacing ??? I was then charged to have the bolts tightened - nice. They said I must have have had work done somewhere else because they never touched the bolts ??? The positive comments on this site can only be made by knowledgeable customers that the dealership is unable to rip off. This is the 3rd vehicle purchase through John Bear - that's what you get for being a loyal customer. Hope this helps someone.

A family member brought a car in to be certified, July - prelovedhomes

A family member brought a car in to be certified, July 2023. The certificate expired some 35 days later with the registered owner not having transferred it to his grandson, as yet. We took it back in to be re-certified, which they did but, they missed a leaking fuel line, a loose tie rod and a badly worn tire that needed replacing. Initially, my complaint was met with the wall of zero accountability but they backed off and told me to bring the car in and hey would see what they could do. Trust destroyed, We took the car elsewhere to be repaired.

I had a service issue with my new Cruze ( That i did not purchase from Mackenzie"s... Regrettably so...) I brought it in to the service department and was treated with at most respect and my issue was resolved in a respectful and timely manner, Would highly recommend this dealer for anything, From service to sales. The owner even had the time to speak to me personally, excellent experience.

Worse customer service - Roy

This dealership kept my vehicle for weeks, I did not have use of my vehicle for months because they could not or was unwilling to fix my very Cadillac that was under warranty. Although they kept my vehicle for an extended time, I was told that any courtesy vehicle will be billed to me. The service ambassador that dealt was hard to deal with and she gave excuses and lied constantly. What a shame for such a hugh dealership. I will never go back to this dealership and I am not recommending this dealership

Top notch service and quality work - VanWolfe

Had an accident with my Cayenne S recently and the dealership and body shop have been outstanding. They are handling issues with the insurance company, ensuring we get all the quality service, parts, body work and damage inspections we really need. The work is ongoing, but based on this and my prior experiences with Marks, I wouldn't even think about going anywhere else for my Cayenne's ongoing care.

Dishonest Service Department ! - larrychin

Dishonest Service Department !! My elderly mother had her car into the dealership because it was not running smoothly. The diagnosis was a faulty ignition coil. which was replaced and a injector cleaning also done. This cost $1077, $791 of which was labor and only $271 were for parts. They then told here that she had a faulty water pump that needed to be replaced for $2000. When I heard that, I told her I would take it to my mechanic for second opinion. When she told them she was going to pick up the car, she was told she could not have it because it was not safe to drive, at which point we told them to release the car, which they did, but only after they charged $359 to "put it back together". It should be noted that diagnosing a leak in the cooling system should have been done by pressurizing the system and looking for a leak. There should not have been anything to put back together. After we got the car I took the car to my mechanic who diagnosed the problem as a loose hose clamp. Not only that, but the water pump appeared to have been replaced recently and there was nothing wrong with the water pump. Cost for diagnosis and replacing the clamp, $158, a far cry from $2000 ! That is the last time we go to that dealership for anything !

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.
