Transmission Solenoid problems of the 2007 GMC Acadia

Purchased this car Aug 2017 fixed moon roof clogs and leaks on the inside, passenger side window will not go down on drivers controls, stabilitrak system shuts off, making the car hard to steer, check engine lights comes on, codes 700-shift solenoid a stuck; code 752-transmission control system, acceleration is unreliable and goes into "limp home mode" where it will not allow me to go over 40-45mph and rpm does not go down, it will not shift easily from park to drive or reverse.

2007 GMC Acadia with 108,000 miles. Check engine light appeared and the transmission went into safe mode and would not shift out of 2nd gear. Code generated was the "shift solenoid stuck open". Transmission shop stated that the transmission will totally fail soon and needed to be rebuild at a cost of $4500. The transmission guy said that I was lucky to get over 100,000 miles because they usually fail between 80-90,000 miles. He stated it was a horrible design for a transmission and inadequate parts were used inside. Not an uncommon problem for this vehicle. Researching all of the complaints, there should be a recall. Gm's attitude is that the warranty is up and it's your problem, so you must pay for our design flaws.

The transmission on my Acadia has died. My wife went to pickup our son from a friend's house. The car drove fine on the way over. When they got back in the car, to leave, the car would not go into gear. She could move the shift lever into reverse but the car wouldn't go. The engine would just rev. She turned the car off to go ask for help. When she started it again, it would go into gear but the check engine light was on and it didn't sound right. When trying to drive the car, it would slip in and out of gear and had a whining sound. When reading the codes, I found the following: p0700 powertrain - transmission control system, p0752 shift solenoid "a" stuck on, & p0797 pressure control solenoid "c" stuck on. I haven't had it checked by a mechanic yet so I don't know the real problem. The tow truck is taking it to the shop tomorrow. I'll have to update once I get the diagnosis. 67k miles seems a little premature to be losing the transmission.

I parked my car last night with no signs of transmission problems. This morning I get into to go to work and I notice that the vehicle will not shift out of first gear. Problem is diagnosed and found to be "transmission shift solenoid a". Deal stated that they are not aware of any such problems with this make and model. Aafter researching online I discover many many of the same exact issues with same make and model. Dealer is requiring $3000. 00 the repair.

When pulling out from a stop, the vehicle shifts very hard from 1st to 2nd gear. Sometimes there is a loud crunching sound and occasionally it will shudder while driving. The vehicle hesitates all the time when trying to accelerate, and will not downshift when going up hills. Erratically changes gears even while traveling at the same rate of speed, like it is not sure what gear to be in. The check-engine light will come on and it will not change out of 1st gear, and it will stay this way until the vehicle it turned off and left alone for a few minutes. Then the light will go away after it is driven about 50 miles. I have had the shift solenoid replaced ($450 expense) which is that the code said was wrong, and this did not fix the problem or help anything.

The contact owns a 2007 GMC Acadia. The contact stated that the vehicle would hesitate to accelerate and operate sluggishly. The timing chain was replaced by the dealer however, the failure late recurred with the illumination of the check engine warning light. An engine flush was performed on the vehicle and the failure subsided for three weeks before recurring. The vehicle was taken back to the dealer, who advised that there was a seized solenoid in the transmission, which would require replacing. The vehicle was not repaired. The failure mileage was 120,000 and the current mileage was 130,000.

When I purchased the vehicle there was a noticeable whine in the steering. I asked the salesman and he said that noise was typical with Acadia's and there was no issue with the car. When I took it in for an oil change at a different dealer right before we left on vacation, I was told the power steering pump was going out and needed to be replaced immediately. Did that even though we were delayed going on vacation and subsequently had it replaced two more times as well. Also have had leaks in the sunroof that continue to return, and have now messed up my power window controls to the point that I can not control any of the other windows from the drivers seat. Have had to replace the water pump, front struts, and now the solenoids are being replaced as well. When I purchased my car it had right at 54k miles on it and I had an extended warranty, that covered my power steering pump issues, but I have had to deal with the rest. I will have now put almost $3k into repairs that seem to be very typical with this car, based on what I have read on the internet.

03/01/2008 - 16,000 I wasn't able to steer, power steering is completely out on the middle of the road 12/01/2008 - 32,000 - misfire in the 2 engine cylinders and was making lot of noise, dealer took 5 weeks to fix the problem 06/01/2009 - 41,000 issue with the engine making noise at start, had to make multiple trips to the dealer 06/01/2011 - 66,000 water pump leaking 03/01/2012 - 72,000 brake control failure 06/29/2012 - 76,000 broken wave plates, evaporater solenoid, and transmission failure most of these issues are very common in this model, GMC need to recall and fix once for all rather than waiting on the issue to happen on each vehicle.
