Car has had excessive oil consumption since start. Easily consuming 1-2 quarts of oil on monthly basis. Had timing chains replaced at 75000 miles. Car suddenly stopped without warning 1/16/23 and completely shut off while driving. Now, at 170000 miles the engine is blown, due to chains loosening, and valves getting bent and scattered.

Vehicle stalled at red light on city street. Vehicle ended up needed 4 quarts of oil which caused a broken timing chain and complete engine replacement. Engine was the 2.4L ecotec, which has bulletins for oil consumption issues. The low oil light did not come on in the vehicle.

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

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.

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.

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. Three separate people have driven the car and confirm the noises. If there is a structural weakness it would be a safety concern.
