Although I have only owned the Buick for one year, it has been a year of trouble free operation. Two oil changes and 13,000 miles later (first at 3,000, second at 13,000), and that is all the service has been - less than $100.
The oil sensor is a nice touch, you only get oil changes when the car tells you it is time too based on driving conditions. It is very comfortable and the whole family likes its features as mentioned below. The teething problems the people in 2008 seems to have benefited the later model years with additional features such as GPS with traffic navigation, more horsepower with the same gas mileage, and overall just a better car with imrproved transmission performance.
The family likes the audio/video capabilities that come with the car such as the Panasonic video system, bluetooth and OnStar phone calls with built-in directory listing, and GPS navigation with XM traffic.
All of these features have proved their worth over the past year.
For example, had a three hour drive to a wedding soon after purchasing the car.
Relatives left our home 30 minutes before we did.
GPS/XM traffic warned us of impending 20 mph traffic and detoured us off the highway onto a state route where we by passed the construction and beat those relatives by 15 minutes!
We saved 45 minutes driving on that trip.
We have learned to trust the navigation system.
A very good car.
Although better fuel economy would be nice, it is pretty good for a car this size and a hybrid on this platfrom (I think it is callled Lambada by GM) is not really possible as engineers have told me that there is not enough room to do one in the current design.
Since the car weighs 5000 lbs, not really reliatistic to get better transmission performance better with all that weight and a big V6 moving it around, although that would be nice.
Overall a very good car.
Auto trans has a hard shift from 1st to 2nd and or 2nd to 3rd. This occurs most of the time. I expected the shift to be smooth all the time, especially in a vehicle the cost of an Enclave. This problem is anoying to me. Otherwise I like the car. Dealer CSR said its nornal for that vehicle. I thought the shifting would improve over time with more milage,but its still the same. After 70 years plus of making auto trans you would think GM could get it right. Would not buy another Enclave due to this problem.
Purchased my 2010 Buick Enclave in August of 2010 with less than 100 miles. Enjoyed it until recently when the electronics started to fail. While driving the dash would fail and the a/c would stop cooling. Now it fails to crank off on on and the dealership states there is nothing wrong with it!
Purchased vehicle 4 months ago. Since then, exhaust system had to be replaced due to a harmonic vibration that could be heard while accelerating. Vehicle delivered with imperfections in paint (Tri-Coat Color). Two bubbles are visible and GM is still deciding as to whether the entire left side of vehicle will be repainted or take a chance that there is no air beneath bubble. Engine has a rough idle and is loud compared to foreign vehicles I've owned. Vehicle oversteers somewhat.
Easy to maneuver, OnStar, Navigation System user friendly.
Quality control. Interior of vehicle has a lot of plastic which is evident compared to other vehicles. Service at dealership is still not consumer friendly compared to Lexus or Mercedes. A lot of work yet to be done.
