Takata recall it keeps shutting completely down in the middle of highway and this affects everything steering, complete loss of power to vehicle. No codes to indicate something is wrong !!!! Extremely dangerous this has continued to occur even after parts have been replaced brand new. More than 5 times already. This will most certainly lead to death. I have 3 children with me at all times. That's 4 lives that could be lost because of this problem!!!! . We have been extremely lucky because it has shift down in the middle of the night and bridges where there is nowhere to get on the side but remain in the lanes where traffic is 70 MPH and up!!!! This needs to be recalled immediately!!!!

Please help me out and see about a recall so people won't get injured or possible killed over this issue that they know about.

When travelling home on the highway after school shopping with my two children my vehicle suddenly reduced power, became uncontrollable and wouldn't allow me to get out of the way of the rapidly approaching vehicles behind me in time. I was able to get to the shoulder, after the reduced engine alert appeared. Stabiltrak was also disabled and one more feature I cannot remember. I had to shut my vehicle down and sit with two children in the car waiting for the car to somehow right itself. After 10 minutes I tried turning it on and the errors were gone and the car drove again, except rough. I took it to the local auto store and the diagnosed it with the code reader as tac. Throttle body. The person at the counter said they see this all the time with this vehicle. In fact, it should be a recall since it's so common and a clear flaw in the design. To the tune of $199 you can replace the part and have the same thing happen all over again at some other random, unsafe time! Thank you gm for yet another unreliable family vehicle. I will have no choice, but to replace the part, as this is the car used for every day transportation in my household to school, work and back. Researching the internet horror stories can be found everywhere. It seems tragedy has to happen to make this $200 part a recall. Please redesign and replace. This mom cares for her kids.

While driving at interstate speeds in 90+ degree weather, the 2008 gmc acadia experienced a complete loss of power. Engine quit along with all electronics, power steering and power brakes. Let car sit for 20 minutes and it started up and drove fine for a week or so then the same issue occurred again. This has happened 3 times within 5 weeks. The vehicle has been into an independent mechanic and two dealerships. Of those dealerships, we have taken the vehicle to the local autonation gmc dealer 3 times over the course of 2 weeks and all groups who have looked at the vehicle stated that they could not find and "codes" after running the computer diagnostics. We have requested an on-board diagnostic computer to be ordered from autonation gmc park meadows (co) but have received no response. This is a very dangerous issue while driving at highway and interstate speeds. Have researched other consumers with the same situation on the federal safety agency website.

While driving the vehicle at a normal speed (55) on a highway, a dinging sound comes on and the car goes into reduced power mode, losing speed. The stabilitrak and the traction control warning comes on. This makes it difficult to cross traffic at intersections as the car will barely accelerate. There is no warning that this is going to happen. Also, the cars behind you do not know why you are slowing down. Then when you turn the car off and restart it, the lights go off and the car drives fine. After three trips to the gmc dealer, the throttle body was determined to be the problem. Gmc has issued special circumstances warranty on the 2007 & the 2009 but not the 2008. I do not feel that the warranty is sufficient. I do not understand why there is not a recall because after searching the forums, I have found that there are numerous complaints with this happening. I had my grandkids in the car with me and we could have been hurt when we had the sudden loss of power we experienced.
