The Enclave has only been available in Canada for about 2 - 2 1/2 weeks. I visited my dealership, in Brampton Ontario, today and am very impressed with the product. However, when I was leaving the dealership I spoke to the parts manager and he informed me that one of the sold units was in to have the transmission replaced. I think I will wait a while before I buy a unit with the new 6 speed transmission. It would be interesting to note if others have come across this situation.

That's exactly why I'm waiting a year or two before purchasing. I'm truly impressed with this car, but buying first year can have some huge drawbacks.
 
Now mind you, this may be a random incident as well, but I just hope this doesn't become widespread and cause a good thing to crash and burn.

Enclave Check Engine LIght (Cam shaft position sensor) by mfjohnston
Jul 19, 2007 (6:22 am)

We just purchased a Buick Enclave and love it. However within 7 days the check engine light cam eon. A first attempt at the dealer "recalibration" proved short lived and light reappeared within an hour. Further diagnostics revealed the error code pointed to the cam shaft position sensor. They replaced the sensor as the cam shaft was in perfect position. Operationally the engine runs perfectly. That did not resolve the issue. The engine is running perfectly the cam shaft is clearly not out of position. (I believe this engine has variable valve timing). GM told the dealership to check all the wiring which after two more days of labor came back fine. They are not going to try to swap out the computer.
 
I havent seen any problems like this with this platform (Enclave, outlook or Acadia). My fear is this is something that will be very difficult to find. It's a shame because we like the vehicle very much and operationally everything is fine. We just can find the abberation causing this error code. Hopefully swapping the ECU will resolve the issue. The dealership has been good to us. I suspect they are sensitive because this issue appeared on a new platform only a week after purchase.
 
Does anyonw know what else could cause the cam shaft position sensor error code besides the sensor itself and erroent cam shaft position?
 
Any information will be helpfull.

This may sound too simple, but try a new battery.

Check engine light and service stable track by bernh

I have had my Buick Enclave for about 3 weeks and just rolled 1000 miles. We were on vacation and got into the vehicle and it displayed a message service stable track and the check engine light was on, when we tried to put it in drive the car reved up and didn't want to move, we then shut the car off and started it back up, the stable control message went away but the check engine light was still on. We then called onstar, they ran a diagnostic on the car and told us there was a malfunction in the stable tract control and transmission. This problem occurred on a Saturday which pretty much left us without a car until monday. We called GMC roadside service which took 4 hours of waiting around till they finally picked up the car, after they took the car to the nearest GMC/Buick dealer they then checked the car and said it would have to stay overnight and that it was a sensor problem, The next day we then received a call from the dealership who then said that it wasn't a sensor problem but a problem with the software and was told by GMC that there was not a fix for this problem, we were then told by them to take the car and drive it like this until there is a fix for it and whenever this happens just pull over and restart the car to reset it. I guess this is easy for them to say to get rid of us but you pay 45,0000 for a vehicle pulling over on the side of the road and restarting the car is bulls**t. We then called the GMC customer service who then told us to pick up our car and drive it back to the dealership we purchased it from which is approx. 600 miles away and was told they would fix it. OK, so you mean only certain GMC/Buick service departments can fix this problem. The car still isn't fixed and our next step is taking it to the dealership of purchase hoping this will get resolved soon before GMC has a lawsuit filed against them. Oh and also thanks to this wonderful car everyone is waiting for, it ruined my vacation.
 
If anyone else has had this problem please respond with your results. To the new Enclave owners and those waiting for their's "BEWARE".

Problem with high RPMs when climbing hill, slow to downshift by lwolf99
Aug 26, 2007 (5:17 am)

Hello. Looking for a little help...
 
I have an Exclave CXL AWD that I purchased in late June. It has the Towing package, with the trailer hitch with the heavy-duty trailer towing provision (I got this option for my bike rack, not because I do any heavy towing).
 
Here's my problem.... we live towars the top of a fairly steep hill - about 1/2 mile long. As I climb the hill, my RPMs get up to slightly over 5,000 before the transmission finally downshifts, and then RPMs then go down to about 3,000 or 3,500.
 
I have taken this road home every day for the past several years. My old 2001 Chrysler Town & Country Limited minivan did not do this. I do not know very much about cars or transmissions, but it just "feels" wrong. The engine really seems to be working hard at 5,000 RPM.
 
Any ideas/comments if 5,000 RPM is okay, or if it is a problem? Any ideas/comments on how to corret this issue? I heard something abotu an upcoming flash update for the transmission for Acadia.
 
Last note... Otherwise, I really love my Enclave.

Definitely not that simple. The battery would not cause the e check engine light to reappear after codes reset and would provide a proper error code. The problem was eventually found. It was a sing cam manufactured a few mm out of spec. They had to replace the entire engine as that engine has a fairly complicated variable valve timing system. I

I guess this is a known issue. The cons for this vehicle on edmunds says that the transmission is hesitant to downshift, basically a mileage optimization. I also read that they have a manual override for this situation. So, maybe you should be using that when you feel its not downshifting automatically.
 
I like this vehicle just a little cautious in buying now because of this thread. Keep posting about your experience. I am sure if there are a lot of similar troubles noted/posted there would be recalls sent out for updates.

5,000 miles and too much noise by dianej
Jan 09, 2008 (6:59 pm)

After 10 weeks of happy ownership and 5,000 miles, our Enclave got noisy somewhere north of the drivers' seat. Dealer diagnosed as left front hub, so replaced hub and proclaimed the noise/vibration solved. I picked up the car today. I don't think it's any quieter, and I've gotten 11.7 mpg with the in-town driving I've done since picking it up; far below my usual 15-16 in-town mileage numbers. Any ideas?
