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.

Oil Consumption- Burning through 2 qts of oil every 2000 miles. No warning lights coming on. Last oil change my car had no oil in it.

- Reading, PA, USA

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 in 2010-13 Equinox & Terrain, both vehicles listed on TSB 003H with the 2012 Verano. https://www.classaction.org/media/sanchez-et-al-v-general-motors-llc.pdf The primary cause: faulty piston rings and defective crankcase ventilation system, leading to excessive oil consumption. The oil monitoring systems are defective. -??Reliance on the [system] instead encourages owners to drive with a false sense of security.-?? -??Problems include, but are not limited to: unanticipated engine shutdowns, engine stalls.-?? -??[This] is a substantial safety concern because [failure]-?? cannot be reasonably anticipated or predicted.-?? To allow GM to ignore this documented and persistent issue, without further investigation, would be a failure carry out the NHTSA-??s core duty: to save lives and prevent injuries. Thank you.

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.

Replaced many components and still has cylinder misfire. Replaced coils. Spark plugs. Vvt solenoids. Pigtails for vvt and still jerks, stalls, and radio doesn't work.

Car engine started making noise in front right side. Had oil changed 2000 miles prior and there was no oil when checked. Mechanic said the motors are known to have the timing belt go out and the pistons. There are recalls for this issue, however my VIN number doesn't come up!! Have had the car 2 months!!!! Pretty pissed off!

Car using excessive oil, but not leaking. Non oil light ever has come on. Car also showed P0011 which ties in with issue.

- Schaumburg, IL, USA

Purchased the car used with 65K miles and everything seemed good. At around 72K the car had a loud pinging noise. I checked the oil and the dip stick was dry. I changed the oil and filter to be safe. The car has been using a quart of oil every 2000 miles. At 80K the check engine light came on. In pa that means you do not pass inspection so we had to have the engine serviced. The bill was only $212 dollars for two valve position solenoids. I did a complete oil and filter change then also. At 1712 miles later the engine light came on again, the engine oil was 1,5 quarts low again. I guess I am in the same boat as most of the others with high oil consumption, shafted by GM again. I do not understand how a company can sell something so badf and get away with it. It seems all of the GM vehicles with the 22.4 liter 4 cylinder engine have these issues. The shame is the car itself so far has been pretty good except for the oil issue. When will GM start to stand behind their product?

The system air bag notices keeps coming in the car, when you put your seat beat on it goes away. Also the oil button doesn't come on, the car constantly shakes and the check engine like keeps coming on after even being repaired. I needed a fuel pump and that's been fixed but the problem is happening again

- Philadelphia, PA, USA

Excessive oil consumption. Low oil light did not come on causing car to produce "engine power reduced" warning on dashboard. Less than half a quart of oil in engine caused timing belt to break along with head gasket to collapse. Issue with car happened at work sitting in stationary parking spot

- Ypsilanti, MI, USA

As I was driving in the city the car suddenly stopped and there was a smell of burning oil. I noticed dark oil on the pavement. I was good about changing my oil per manufacturer recommendation. I wasn't aware that other similar cars had this same issue. I wish a recall had been done prior to this major loss.

- Shawano, WI, USA

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.

The contact owns a 2012 Buick Verano. While driving, the check engine warning indicator illuminated. The vehicle was taken to an independent mechanic who diagnosed that the camshaft solenoid failed. The vehicle was not repaired. The vehicle was taken to kendall auto group (1400 executive pkwy # 400, eugene, or 97401, (541) 335-4000) and the contact was informed that there was no history of a failure code; however, the piston and rings. Were repaired. The contact stated that the check engine warning indicator illuminated. The contact took the vehicle back to the dealer where the contact left the engine running and showed the technician the failure. The technician found the code and informed the contact that the camshaft solenoid needed to be replaced and an oil consumption test was needed. The vehicle was not repaired. The vehicle had an oil consumption test performed on three different occasions. The contact was informed that the vehicle was down to three quarters of a quart of oil. The contact stated that the failure continued. The manufacturer was notified of the failure and provided case number: Sr 9-5484491631. The approximate failure mileage was 81,207.

I have a 2012 Buick Verano with about 115000 miles on it. I have been to several GM dealers with complaints of excessive oil consumption to the point of there being no oil in the car whatsoever and they claimed there was no issue. I went to a third service center and they did over 700 dollars worth of work that needed to be done because of damage to the engine from low oil. General Motors customer service denies that there is an issue even though there are recalls for other vehicles with the same exact engine (2.4 liter 4 cylinder). I do not feel safe with this vehicle knowing there's a possibility of engine failure while I am on the highway. I have service records to prove I've had this work done and I've been to several dealerships. There are also numerous complaints about the same issue I am describing online. I do not understand why this issue hasn't been recalled because it is something that is happening to numerous vehicles and in addition there is a recall out for vehicles made by General Motors with the same exact engine as mine.

- Forestdale, MA, USA

Excessive engine oil consumption. Need to add more than 3-4 quarts every 2K miles. Note that low level oil light never turns on. At a recent oil change in late July '19 there was ~1 quart of oil in the reservoir when oil was drained. Oil changes have been performed at specified intervals since purchased in July of '15 (~39,900 miles when purchased). Started noticing excessive oil consumption in '17.

- Waterford, WI, USA

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
