Complimentary safety inspection and brake repair
My front brakes and rotors needed to be replaced at 33K miles on a 2018 Buick Enclave. Total repair including the recommended brake fluid flush came to $601 including Pa. state tax. So without tax about $540. That seems high. Might try Midas or some other local garage next time. I question if I really needed the rotors replaced. I paid more but maybe got a good job done, and quality GM parts. Complimentary safety inspection and top off all fluids. I would have been nice to see a report of the inspection. Like measurement readings or what was inspected. Ex. even though my TPMS (tire pressure) was not lit, I knew one of my tires was low about 29-30 psi. According to OnStar Recommended tire pressure: Front: 35psi | Rear: 35psi I still saw my tires low. I think a little more information would be good.
This truck is great if your not trying to haul 10k lbs.

Found a SVT Cobra that caught my attention. Information, additional pictures, and offers went good. Shipping was handled on their end. Smooth out of state transaction, would purchase from again.
Reliable and comfortable.
I bought this 2017 Tahoe w LT trim new. Have 60K on it now and have had no issues with it. We are not towing with it or doing high speed racing so we find the 5.3L Motor is smooth and quiet (and have not had any lifter issues which others have reported). Transmission and suspension also smooth. We keep Michelins on all our vehicles and have found this Tahoe very quiet and comfortable for road trips with 4-6 people and luggage. The LT trim pkg deleted some comfort items I wish I had (like heated steering wheel) but it still is pretty much leather-and-loaded so it was a good value at the time. I have had Suburbans for 35yrs before purchasing this Tahoe and I will probably go back to a Suburban for the extra cargo space when I trade this Tahoe in. But this has been a nice and reliable vehicle for us. No complaints.

I have loved and owned Chevy and GMC midsized trucks
I have loved and owned Chevy and GMC midsized trucks since 98 when I purchased a used S-10. My latest purchase is a 2021 GMC Canyon Denali bought brand new. It's been a great truck until my power steering unit went out due to corrosion. It only has 32,200 miles on it and I have never gotten it wet other than car washes and driving in the rain which is normal conditions. I had purchased a mid grade extended warranty through GMC after my lease was up and purchased the truck. I am being told this is NOT covered due to it being external wiring. So I feel this is a manufacturing malfunction and bad engineering for water to be able to get in to cause such corrosion so beware. This is an open case filed with GM currently to hopefully rectify the matter.

I purchased my 2016 GMC Terrain SLT in 2018 as a gently used vehicle with only 21,000 miles on it. I never had issues with it. I kept it regularly serviced and had to replace tires. At now over 93,000 it has been a comfortable and very reliable car. The only feature I wished it had was rear air conditioning. Living here in the SE it gets hot and it takes a “minute” to get the back of the vehicle cooled down. However, I rarely have back seat passengers, and thankfully, the really hot weather lasts only a few months! I have been very pleased with this car and would recommend it to others. I traded it in a week ago for a larger car only because I need the room for a grandchild, and my elderly parents.

2019 Sierra SLT X31
I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

Great Diesel truck when emission sensors work
Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.

Worth the wait to finally have it
We drove two states over to McKenzie Buick GMC in Milton, FL to meet with Nick and make a purchase on our new Yukon Denali. Customer service was top notch. We were going for their 2019 Yukon Denali to replace a 2008 Tahoe LTZ. We are very pleased with the vehicle. The upgrades are wonderful. Love the cooling seats, the wifi, the HUD and even days after our purchase they have reached out to check on how we were and mailed us a small gift that meant so much. We will definitely use them again if they ever have what we’re looking for on a future purchase. - Brandon Howell 2019 Yukon Denali

2015 GMC Terrain Review – Reliable and Comfortable
2015 GMC Terrain Review – Reliable and Comfortable SUV: I purchased the 2015 GMC Terrain as a reliable daily drive, and it has exceeded my expectations in many ways. The interior is spacious and comfortable, with high-quality materials that give it a premium feel. The seats are well-padded, making long drives enjoyable. In terms of performance, the Terrain delivers a smooth and stable ride, with responsive acceleration that meets my needs. The fuel efficiency is reasonable, which helps with long commutes. The exterior design is bold and distinctive, giving it a strong road presence. Reliability has been solid, with minimal mechanical issues over the years. Maintenance has been straightforward, and the vehicle has held up well. Additionally, my purchase experience was fantastic, thanks to Claudia Reid/Sales. She truly took the time to negotiate pricing and ensure I got the best deal possible. Her dedication and professionalism made the entire process seamless. Overall, the 2015 GMC Terrain is a great choice for anyone looking for a comfortable, spacious, and dependable SUV. Would I recommend it? Yes, especially for families or commuters seeking a balanced vehicle. Thank you, Auto Club of Edison!

I bought my gmc canyon used with 29,300 miles on the odometer. It has the 2.8 ltr I-4 turbo diesel engine. I'm towing a 5,000 lb travel coach. First thousand miles was today. The small engine gets for me astounding fuel milage. Towing the coach i averaged 22. 8 mpg on a trip to the Eastern Sierras. 368 ft lbs of torque is more than enough to haul the trailer to 10,000 + ft elevation. Just be patient and use the torque to tow up a mountain. The fit and finish is excellent, the blue metallic paint turns heads. After 3 yrs a good waxing had it looking showroom new. This is my first gmc ever. If it holds up and runs 300,000 miles like the sales rep stated it's capable of doing. I'll let you know. The one down side is the emissions on the engine can cause reliability issues. Advice i found on a forum says use a good quality injection cleaner in every fill up . Every fill up for the life of the truck. They are capable 300,000 and higher if we'll cared for.

Perfect for us!
As we age, our reaction time may become slower. This vehicle is loaded with features that make me a safer driver. It connects wirelessly with my iPhone for hands-free Apple CarPlay. Love that! And the Acadia is a dream to drive. It’s the perfect size for me and my family
