I have had no real problems, except maybe the cheap tires they put on when its new. 23,000 miles and down to the wear bar. Sometime the info screen is frustrating to get the right pressure to find songs with the music channel I have. I do worry about the short warranty. 3 yrs 20,000 miles which is over. I cant believe that I overlooked that. I worked at GM for 8 yrs so I got the discount and that was why I bought it. If I had to do over I would by one of those Asian cars with 10 yr 100,000 mile warranty. Though I have had no problems so far. I only put about 7500 miles a yr on my car. I have 23500 now.

Purchased pre owned with 56k miles. Everything seems to be great thus far. The only thing is I’m not sure the AC actually works as I normally keep it set to the “Auto” function. And when the temperature got up a little warmer than normal it didn’t seem to make the adjustment.

Great Honda dealership
Jeff Reed provided great service. He is attentive to what we want to know and goes the extra step to make sure he provides that. All the people we spoke to were professional and friendly.
Fate..? Maybe.
I was kind of forced into my 2022 Envision during the inventory crisis post covid. My Alfa Romeo Giulia lease was totaled. I lost the market equity as Ally being the lessor is entitled to retain all over payment. I needed a vehicle quick. Upon arriving at my local Buick GMC dealer I asked what was on the lot long enough they wanted to move. The answer was a Preferred awd Envision in Burnished Bronze. I bought it, was surprised with the "premium sound system" (not Bose). Love the quiet smooth ride. This 2.0 is not the Alfa's 2.0 that is for sure, but I have had no issues getting around or through slow traffic. All in all... I was, and continue to be, a year later impressed. Well done Buick, just wish it had LUMBAR.

Was looking for safety and security in a suv Comfort for neck and back were important this particular model goes above and beyond. Ride is smooth and quiet with what engine doesn't have in speed it has in hidden torque in motor. Black on black with black grill and rims with crushed glass in the paint, so many compliments especially how masculine looking the vehicle is The dealership Garber of Fort pierce has been amazing from sales to service to accessories Best purchase I've made in years highly recommended

Above and Beyond Customer Service
This review is in full support of Clement Hyundai – a dealership located in Wentzville, MO – which has shown remarkable, above-and-beyond customer care. At the end of our leasing period for a 2020 Palisade, my wife and I purchased the car outright. The transaction was handled smoothly and thoroughly by salesman Jeremy Null. Following that, our car needed to go through a few inspections for the warranty coverage. In doing that, there was a faulty wiper installed -- requiring the car to go back in to get it fixed. While this could have been a very frustrating experience – as we live more than 30 miles from the dealership – the team at Clement Hyundai went above and beyond for us, recognizing the inconvenience. Especially Jeremy and General Sales Manager Patrick Piper. They picked our vehicle up and delivered a loaner, as well as provided other coupons etc. to make up for the situation. When my wife realized she left my daughter’s dance recital tickets in the glove box, they drove out to our home to deliver them to us. That’s the kind of operation they run: one that has the customer at the center of what they do. I’ve never experienced such superior customer service from any other local dealership – and I’ve owned BMWs, Audis, Toyotas, Hondas, Fords and other makes and models. Clement is a first class operation and should be super high on your consideration list for purchasing a vehicle or getting service.

My only complaint is that I cannot seem to close the door mirrors. Small complaint and not really a flaw but cosmetic. The car is amazing. It has plenty of room and acceleration. It is comfortable and luxurious too.

Worked with Randy Bollinger at Sunset Ford. He answered all my questions and was not pushy. Gave us time to look at all our options. Overall experience was terrific. Will definitely return when needed.
Bought it used in May 2022.
Bought it used in May 2022. It's a 2016 Buick Enclave awd Tucson Edition (displayed as leather). It's a nice car, was around $28,000 from carmax with 70k miles. It's first problem occurred in June 2025 when the ac stopped working, it got fixed. Only major problem was at 105k miles when the transmission had trouble. Reason why was because the dealer said it had the 4,500 lb tow package, but it was missing a crucial part needed to tow. Transmission was fixed, and car still runs fine to this day at 108k miles. 3.6L V6 288 horsepower.

For a car made in China, with their reputation for putting out shoddy products and looking at their buildings and roads that's falling apart as we speak, I was totally surprised at the quality built into this car, not knowing at the time of purchase that it was made over there, which would have made me pass on buying it. But we are talking GM here, that built the plant in Shanghai, who took every part over there just to use their labor only to assemble it, and they did an excellent job. I figure that GM pays them better than all other jobs in that country and they don' t want to lose that job, so they do the best that they can when putting it together. We are at 105,000 miles now, and did all the oil changes and did go through the hundred thousand mile checkup and all fluids changed, and it has yet to have anything to go wrong with it except for changing out the 5 year gel filled very expensive battery *at 5 years on the dot, and the second set of tires. Even still has the original front pads on the brakes, but due to my real easy driving and feathering them coming up to stop lights, trying not to let the stop/start system engage at full stop, and have been doing an excellent job in timing lights and breaking one law by doing 'rolling stops' at stop signs with no cross traffic in sight. I'm a person that drives a vehicle until it rots down, like I did my '84 Toyota diesel pickup that I put over 800K on it until finally the box frame under it rusted in two, forcing me to park it forever, with the engine still running in it. And with this car I'm shooting for the same mileage before it falls apart just from so many miles on the body.

Ms. Mary S. Scialfa
CarMax made the purchase of my vehicle run smoothly, without having to go to the Division of Motor Vehicles. They addressed my concerns promptly and, when new keys had to be made, offered a "loaner" vehicle until the problem was fixed. I recommend CarMas to everyone!
Luxury that delivers
I absolutely love this car. While being priced on the high end, this is a luxury car that delivers. With 310 horsepower, 9 cylinder transmission, and luxurious interior appointments, this car delivers power and can definitely leave you feeling spoiled. The only issues that I have seen are really minor. The fuel door, when opened, can actually dent the body of the vehicle. The interior shade on the moonroof is a manual latch, not mechanical. It simply seems a little cheap compared to the rest of the car. My model is an Avenir model, but it does not have the advanced cruise control or the self parking modes. It did not have a significant price drop for not having these options and I am not sure why an Avenir model did not have all of the options available. I had to buy it during the chip shortage and took what was available. Altogether, this is the nicest car I have ever owned and I am very pleased!

Tech found bad coil, replaced and repaired, also suggested new wires and battery was needing to be replace really low crank, all work completed and again on the road after 310,000 miles. I have had only good experiences with the service department staff and techs. Sometimes it cost some money but its a machine and if you take care or it, it will last.

I received a welcome greeting on arrival and was taken care of immediately.
