general problems of the 2006 Buick Rendezvous

I've had so many problems with this vehicle. Spent over $4000 in repairs in the last 6 months. The first problem I had was while driving on the highway the reduced engine power light and traction system light would come on and the vehicle would just decelerate and wouldn't go over 15mph. I had it repaired once and was told it was the wiring harness and then 2 months later the same thing happened again had it repaired and was told it was the wiring harness and computer that needed replaced. And now I'm having a similar issue but this time the service engine soon light is flashing but the car doesn't want to accelerate and takes several seconds to even get up to 35 mph. I had this repaired once and was told it was a wiring/fuse issue and that the car was only running on 3 cylinders and literally 2 days after the repair it started happening again. This is ridiculous. My mechanic even told me I should just get rid of the vehicle because it obviously has major wiring issues. It only has 130,000 miles.

Driving down the road when the reduced engine power light came on the service traction control light come on the service engine light came on and the trac off light came on. Couldn't drive faster then 20mph.

We were traveling on the interstate at 65 miles per hour on June 5, 2016 and June 11, 20176. The vehicle just went totally dead. The motor, the power steering, everything. . . Went totally dead. I was in the passing lane and a transfer truck was on my tail and I had to go into the grass median to avoid getting smashed and the truck had to swerve over to miss me. After repeated attempts to restart the car, it started. I went straight to an auto repair shop and they checked my starter, alternator, and battery. Those things were ok and they suggested maybe I had bad gas. On 6/11/13, I was on the road again doing 65 and with no warning whatsoever, the vehicle went dead just like the week before. I was able to pull into a turn lane barely avoiding a rear end collision. We took the car to a repair shop. . When we went to get the car, they told us it was the ignition part that gm was recalling. The mechanic tapped on the part while the vehicle was running and it died immediately. He also asked us if the airbag warning light had been coming on. We said yes it had been for about two months and the check engine light had been on a lot during the last month. We contacted the gm and talked to customer service who told us the rendevous was not yet on the recall list and I would have to pay for the repair myself. I went to the local gm dealer, bachman bernard, and the manager told me he could not help me. He said they were independent of gm and if they fixed it, they would not be able to recoup the cost from gm. Do I have any other recourse? is it going to take a family being killed in a rendevous before gm will take responsibility for this very well known part defect? I have lived through two miracles where my family could easily have been killed because of this known defective part. If I have to pay for this repair, is there a way I can be reimbursed by gm?.
