2012 Buick Verano engine problems

“On 2 separate occasions, I have gone through 4 quarts of oil in 2000 miles. No leaks as verified by mechanic. Just excessive burn. The check oil light does not come on to warn you and says I still have 50% oil life but almost bone dry.”

“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.”

“My car started burning an excessive amount of oil this caused my car to die with no engine warning while driving. My mechanic found it to be completely out of oil. The car only has 67000 miles on it and now I have to constantly put oil in the car. It does not leak it just burns oil. I just drove 400 miles and when I got to my destination my car was completely out of oil again. My motor is not going to last if this keeps happening.”

“Technical Service Bulletin #13-06-01-003H (TSB 003H) in regards to GM’s 2.4L engines & excessive oil consumption. (https://static.nhtsa.gov/odi/tsbs/2016/MC-10116880-9999.pdf) This release not only concedes a persistent issue found in at least six GM models, but more importantly fails to acknowledge the serious and fatal risks as a result of the Oil Consumption Defect. As a direct result of GM's known defect, I was left in a dangerous situation. I crossed a divided residential street, engine stalled and the vehicle turned off, stranded in the middle. It is not unreasonable to imagine other similar situations occurring, leaving people directly susceptible to serious injury or death. Here, the dipstick was completely dry. It took two quarts before any oil appeared on the dipstick. The oil light did not illuminate and I was approximately 1500 miles from my next scheduled oil service. The diagnosis: pistons excessively worn from lack of oil, engine failure. My situation is not unique. https://www.carcomplaints.com/Buick/Verano/2012/engine/engine.shtml Sanchez et al v. General Motors LLC, found in favor of the plaintiffs. The issue: the Oil Consumption Defect, found…”

“The contact owns a 2012 Buick Verano. The contact stated that her vehicle was constantly loosing oil however, there was no warning light illuminated on the vehicle to indicate that the oil level was low. The contact stated that when the oil level was low, the vehicle made a loud rumbling sound. The contact would then top off the engine oil. The contact stated that without the knocking sound she would not know that the vehicle required additional oil. The vehicle was taken to a dealer and an independent mechanic however, the mechanic was unable to locate an oil leak. The manufacturer was not notified of the failure. The failure mileage was 176,768.”

“My car has started to burn oil quickly in the past and I was bringing my car to get oil changes more frequently than the sticker was saying at the dealership. Recently my car showed no oil on the dipstick after my car stopped running. 2 quarts of oil was added and the oil only showed at the tip of the dipstick. My engine was tapping a few weeks prior to my car no longer running. I brought the car to the dealership and they informed me that there was not a recall on my vehicle, but upon checking there was a recall in 2016 for this exact matter. My car is still not running and has been down since October 22, 2021. The dealership is stating that they cannot fix my car because there is not an open recall, but this recall was in 2016 and I was never made aware of the recall nor was I said any correspondences about this recall.”
