Engine Shut Off Without Warning problems of the 2008 Buick Lacrosse

While driving north on alternate 69 highway at 65 mph at 5:00 p. M. , my vehicle abruptly loss power even though I tried to accelerate. The engine shut off suddenly and without warning. Vehicle slowed to a complete stop. I was driving in the middle lane and was unable to get in the shoulder lane because I had no pickup (unable to give gas to accelerate) so my husband and I were caught in five 5:00 traffic with cars whipping around us on both sides and many exceeding 65 mph. I put on my emergency lights and immediately called on-star. I was unable to restart the engine. Thank god for on-star because from that point on, I was in terror witnessing cars coming upon us not slowing until they realized I was at a stand still with lights flashing. The cars would swerve to keep from hitting us. It took the highway patrol and police 15 minutes to get to us but during that time, I relived visions of us being killed on the highway. I can¿t describe the horror, looking out my rear view mirror, witnessing our demise time after time. Those 15 minutes seemed like an eternity. When the highway patrol arrived they closed lanes and assisted in pushing car out of the highly traffic lanes. It took my husband and I both to turn the steering while in neutral. The car was towed to conklin fangman kc dealership and I had to replace ignition coil and module that cost me $933. 16. They said these parts were not on the recall list, which I have found out since then gm has put dealerships on notice of this problem. It has something to do with supplying enough manufactured parts to take care of recall. If I could afford to purchase another car I would because I don¿t feel safe any longer in this car. Emotionally I am still suffering from the trauma.
