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.
