#23 of 112 Re: Buick Enclave transmission downshifting [tourguide]
Jun 05, 2011 (3:59 pm)
i have a 2011 enclave, and i would imagine that it came with the upgraded transmission program 08-07-30-022A. i do understand why a 6 sp. tranny, in a heavy car, with marginal torque would "hunt", and downshift.. they are keeping the engine down around 1600 rpm for mileage .. most other low powered v-6"s, like a G-35 inf. which is as smooth as silk because they keep the engine around 2500 rpm or so, for the torque, and driving experience. the buick is only trying to maximize the fuel mileage,, and can only do so much .my biggest complaint about my 2011 enclave is the very poor shift 3rd to 4th,, it's not at all like the other shifts,, it pauses,, seems to retard the ignition slightly, and then slams into 4th gear.. very, very primitive and i've never had a modern day car shift this badly.. LOVE THE CAR,, HATE THE TRANSMISSION.,

When using the cruise control on my new Enclave, it operates very poorly when hilly roads are encountered. The speed will drop 3-4 mph from the set speed going up the hill, before the transmissions shifts down at least 2 gears and then surges the engine to get back up to the original set speed. Then rolling down the next hill, it increases a full 5 mph beyond the set speed before the transmission then downshifts to slow the car down. What a primitive poorly managed system on a car with a $46,000 window sticker. My dealer just spent 90 minutes with my car only to say it is normal for this car and their other Enclave did the exact same thing on the local hilly roads. He offers no remedy for a car that does not even have 700 miles on it yet.
I am concerned about the re programming I am reading about, that it would reduce the gas mileage, but it is even more troubling that my dealer essentially says I am the first to have this problem.
#25 of 112 2008 Enclave Overheating
Sep 10, 2011 (5:21 pm)
I pull a trailer with my Enclave during the summer that weights about 2600 pounds. I have about 77,000+ miles on the vehicle. While trailering lately my temperature gauge goes up about two lines above "normal" and a message is displayed (something to the effect), "Transmission Hot, Idle Engine".
This has happened about 8 times when driving it last week and this week. I pull over and let the engine idle and after a few minutes the engine trouble light goes out and the message disappears. The outside temperature is about 105 degrees F and I am not able to use the air conditioning otherwise the temperature continues to rise. Now periodically when the transmission shifts, after accelerating there is a very strong jerking of the car. My vehicle is suppose to have a tailoring package. Why and what is causing the over heating and the jerking action?

I apologize for the problems you are experiencing with your vehicle. Were you planning on having the vehicle diagnosed at a GM dealership? Please keep me posted.

I dropped it off at Capital Chevrolet in Austin, Texas. Couldn't make it any further on my way back home from south Texas, Tuesday Sept 6th. It got to the point where it wouldn't shift anymore as I limped into south Austin. Buick dealership is on the north side of town. It is my understanding that the vehicle has a 100,000 mile warranty on the drive train and I also purchased an extend warranty when I purchased it in 2008. John Cummings, Service Rep at Capital Chevrolet, said there was some kind of mechanical defect that resulted in this failure. They have had it since Tuesday of last week and it was suppose to have been fixed today but I never got a call.
My major concern now is why has it been overheating? I first experienced the overheating in the late summer of 2009 when pulling my trailer. If I continued to use the A/C the needle on the temperature gauge would slowly creep up to two lines above "normal" position (middle of gauge). Did not experience overheating last summer because I did not pull the trailer as much as I did in 2008 and 2009.
Any suggestions as to the cause of the overheating? Any solutions?

Unfortunately, I am unable to diagnose the vehicle as to why it may be overheating. Have you heard anything more from the dealership? Have you been in contact with GM Customer Assistance via telephone? Please keep me posted.

My wife just experienced a sudden transmission problem where engine was revving but no connection to drive train. Car was towed to dealership. There was no warning. Car has been fine until this sudden failure. Is there a known transmission problem? Any recalls?

#31 of 112 Enclave transmission problem
Oct 03, 2011 (9:11 am)
We just encountered (Thursday 9/29) an issue where the vehicle suddenly lost power and would not travel over a very slow speed. Immediately drove to the dealer and left it for diagnosis. We were told the next day that we most likely would need a new transmission. This is a 2008 with approx 60k miles on it. We've not heard any resolution yet, but I was disheartened that my one US made vehicle encountered a serious problem like this. Is there a transmission issue with the earlier vehicles? I am assuming until I hear otherwise that this is a warranty issue. It has not been used to haul or trailer anything. In the interim we are in a small rental car that does not fit the needs of transporting kids in sports teams. Any insight? Thanks!

I had a major issue that sounds similar at 105,000 mi. The transmission wouldn't shift out of first gear. Even though I was out of transmission warranty by 5K, my dealer got GM to cover the cost of repair, which was over $1000. I paid $100. The way I look at it, I got a transmission overhaul for (virtually) free at 100,000. I have had a significant number of repair issues (seat, front hubs, rotors, tranny). I'm on my third windshield. I still have affection for the comfort and relative value I get out of the car when it is not in the shop, however.
