Starter Solenoid problems of the 2012 Buick Verano

10/26/15 - car wouldn't start; recv'd jump, replaced battery ($169. 40). 11/6/15 - came out of restaurant, car wouldn't start. Got jump took to dealer. Dealer replaced starter and issue resolved. 11/12-11/car stalled 8-10 more documented times both when backing out of parking spot in reverse and at vehicle speeds varying from 35mph to 67mph on 5 lane interstate during rush hour. Took to dealer and called gm. Replaced two solenoids and some hose, keeping car so tech can drive for 2 days to see if problem can be replicated. I can't determine a cause or pattern and don't get any prior warning, so hoping it does occur in their possession during testing. This vehicle is unreliable and very dangerous. I almost caused a multiple vehicle accident on the interstate and risk injury or death by operating this vehicle. My family is at risk, myself and other motorists. Gm says there is no problem but after seeing the numerous complaints on NHTSA. Gov as well as several other online forums, it is clear that gm is trying to avoid another issue with their vehicles. I have owned gm products since turning 16 and this is completely unacceptable. I have been provided with a dealership loaner and will refuse to take my Verano back as I do not feel safe driving or owning this vehicle. Currently have open complaint with gm but do not have resolution at the time of this complaint.
