2012 Buick Verano Transmission and drivetrain Problems

“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). …”

“Today I was driving my 2012 Buick Verano and without any advanced notice (ie.. Lights illuminated on dashboard) my vehicle lost power and just started to creep to a full stop. The dashboard was black nothing to tell me what the problem was. Thank god they have created a large pull off on the highway or I would have been really hurt. I tried several time to restart my vehicle the restarting process was not the problem it was putting the car in gear every time I tried to put the vehicle in gear it would shut off and the engine light is now on.”

“It has always down shifted hard at about 28 to 30 MPH, we asked the dealer and he said it was normal, I have never had a car do this, and what I am afraid of, is it will go bad after the warranty goes out and I am stuck, I have read other reviews on this and other people have had the same problem?? Please help me find out about this, it only has about 6500 miles on it now, and we bought it dec 28 2012, it was driven by the finance manager at fuson Buick in terre haute indiana,and they sold it to us as a new car with 4 years warranty, thanks and hope that you can help us. …”

“A constant percolating or rattling sound is heard while driving slowly and especially on uneven surfaces. The noise gets worse and more consistent as the car is driven. Since nobody can tell me what it is, I must assume it could be a safety concern. The noise became worse after a strut was replaced at 100 miles. The noise got louder after an attempt to fix it by installing a new coil (f-spring?). I was told that this is a characteristic of the car so they will not make attempts to repair it when I request specific actions. I have heard similar noises in at least 7 other same model cars. …”

“Car jerks when sitting at stop signs, red light, in congested stop and go traffic. It also hesitates when you initially press the gas and are going under 20 miles per hour. The check engine light doesn't come on and when you take it to the dealership they run diagnostic and can not detect the issue”
