general problems of the 2006 Buick Rendezvous

Piece of junk since June when I paid $3,000 for it and have put $1200 into it and still broke down and won’t start (ignition switch/key) and I refuse to pay for it to be fixed nor fixing it myself. . Has to be called home sweet home very soon and I need it fixed by gm ASAP or lawyer will be involved and I’m not sinking anymore into it then I have. . Gm products are junk!!! repair it.

I was traveling down the interstate doing the speed limit of 70mph. Out of nowhere, the car flashed "reduced engine power" light and would not accelerate. Then the "service engine soon" light came on and a red battery light also. The car lost all power and power steering. I had to force the car into the emergency lane on the interstate without wrecking. I turned the ignition off and let the car sit for a couple of minutes and it started back up. I made it about 10 miles down the road and it did it again. Car will not run more than 10-15 mins without shutting off. Will not drive this car!!! very dangerous for everybody!.

I own a 2006 Buick Rendezvous SUV. This SUV has 59,000 miles. In November a sensor light came on that states "reduce engine speed" while driving and you lose all power. This includes steering, brakes, speed and the engine stalls. However the radio stays on. I was traveling on a hwy with a speed limit of 45 mph. I lose control of steering, brakes and speed control. The SUV stalled and I had to change three lanes to get out of traffic. I was concerned about getting hit or hitting another car. This has happened frequently. Two separate mechanics had recommend replacing the throttle body but one said there was no guarantee this would solve my problem. We replaced this part in December at a cost of $400 and now I still lose power and am afraid of being hit or causing an accident. As this week this problem has occurred every day I drove it. Buick insists there are no recalls regarding this issue for my 2006 however there is a bulletin for GMC but different models/years. This is dangerous and I am afraid to drive this vehicle. I cannot sell or trade this in with this type of defect. I feel gm should fix this dangerous defect. Please investigate.

Complete and total loss of steering while driving down highway. Fortunate that there was no oncoming traffic, loss of control, or damage.
