Transmission Solenoid problems of the 2012 Buick Verano

2012 Buick Verano. Immediately upon purchase I noticed the fresh air intake always had hot air blowing through vents. Dealer and gm customer service said nothing is wrong. Other Verano owners would stop me in parking lots and ask me if I had the same issue as they had. It was a defect. After 40,000 miles the timing chain needed replaced; camshaft position solenoid valve replaced; new gasket kit; output shaft seal leaking. At 60,000 miles, the car lost all power while driving 55 miles an hour on highway (other owners- Buick forums - had the same dangerous experience). By lost power, I mean the car suddenly had no power steering, brakes. Gas pedal was not operational. The engine shut off. Piston ring failure was the diagnosis from Buick service. Almost 4000 to fix they stated. None of these issues should have happened with a car with only 60,000 miles. The Verano is no longer being manufactured. Gm should admit that they sold a defective product that did not perform as advertised. After addition investigation, I've discovered that gm was well aware of this problem since 2014. Gm never notified Verano owners of this issue. What's more; the Buick dealership told me there was never a service bulletin issued by gm for this problem. Service bulletin 13-06-01-003h in fact was issued. For all Verano owners, please take note. You may still have recourse.
