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.
I have had nothing but problems. I had to have the timing chain on the motor fixed 2700.00, which is a known problem with the GM motors, the left catalyic converter and the Y pipe replaced 2000.00, both cv joints replaced 450.00 and the AC doesnot work but I cannot have that issue repaired right now. Stay away from GM products unless you like to pay for cars that look pretty in your driveway but wont stay running.
My Enclave now has at least six recalls and at least one was a recall on a recall. Check engine light comes on frequently in cold weather due to misfires. Dealer told me to start adding a fuel cleaner every 3000 miles ($16 a pop). Several times I have replaced some type of computer parts (EBCM will not communicate with PCM, ECM lost communication with EBCM). Replaced both front and rear rotors just after warranty expired. Catalytic converter replaced at 68,000 but was covered. Pressure sensors inside the wheel went bad. Dealer wanted to charge me $90 apiece for ignition coils which I found on line for under $50. Rear liftgate made a terrible noise while going up, told by dealer that was normal, so I cleaned the shafts and constantly oiled, two years later they came out with a recall on those. Only get about 1100 miles to a quart of oil, one dealer said that is normal, another said should be 1800 until they started testing, then agreed with other dealer when they found out it was in the low range. Wife overpaid for what she thought would be a nice vehicle, and can't afford the loss on a trade.
Good fuel economy for such a large car with good reliablity

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.
