Automatic Transmission Torque Converter problems of the 2008 GMC Acadia

Since I purchased the vehicle the service air bag light has been on, now the transmission hot idle engine light is popping on and also service the traction control light and service stabilitrak ligt is coming on. Me my family had taken a vacation to florida and the transmission began to startle all the way back to tennessee leaving us in a devastated situation . I was hoping there was a recall on the transmission and and air bags this is very dangerous as many others has complained about the same issues in the past concerning their 2008 Acadia vehicles this vehicle was in motion on a city expressway with a high volume of fast moving traffic. I went to auto zone and o' reilly auto parts to have check engine test and the following codes appeared dtc p2762 torque converter clutch,p0700 automatic transmission control,p0171 fuel control system. And computer error. I don't know if this vehicle ever me recall but I feel me my family could have been severely injured as the fast moving vehicle was coming behind us as our vehicle lost power and connection.

I've had my GMC Acadia in for service on the transmission 3 times in the last 6 months: speed sensor, wave plate, now torque converter. Dealership responds they are completely independent, and that this is not an issue with this model. However, the failure of the transmission in these vehicles is prominent on GMC Acadia forums. Why has gm not stepped up to own and fix this common issue?.

Purchased 2008 Acadia in March 2012. Eight (8) months after purchase while driving with infant son in vehicle, without any warning or lights the car lost all power. Luckily, a serious accident didn't occur. The transmission had completely failed. The cause was a broken 3-5 waveplate, the transmission had heat damage, and material throughout. Our local GMC dealer service department removed, torn down, and overhauled the transmission. This service was covered under a 5 year 100,000mi warranty. It has been 1 year and the transmission is slow to change gears and shaking rumbling at 20mph and 40mph. I called my local dealer they were unable to set up an appointment for 4 days, the car is now at the dealership. I was told it needs $4,900. 00 of work. The cause of the shake and rumble during acceleration is the failure of the torque converter ($2,000). The torque converter was replaced with a remanufactured torque converter, when the transmission was rebuilt 13 months ago. When I asked gm to replace the torque converter, I was told I was lucky it lasted more than 12,000mi. Very disappointed with gm. The transmissions are defective and the are aware of this issue, they put a band aid on the car until it passed 100,000mi,and no longer covered by warranty and now the consumers problem. I do not consider myself lucky that my car spent 7 days in the shop last November and now has been in the shop 4 days with no end in sight, for the same issue.

I've had three transmissions in this car with only 114,000 miles. Wave plate, torque converter problems.
