Latest Verano engine complaints
I am submitting this complaint to report a safety-related issue involving my 2016 Buick Verano. At approximately 112,000 miles, the vehicle experienced a major transmission failure that significantly affected drivability. Shortly thereafter, an airbag warning light illuminated, indicating a potential malfunction of the supplemental restraint system. An independent mechanic advised that the vehicle was no longer safe or economically reasonable to repair due to the transmission failure and the airbag system warning....

The cost of transmission repair was estimated between $5,000.00 and $7,000.00. The vehicle could not be safely driven, sold, or repaired, leaving me with an inoperable vehicle and an outstanding loan balance. I am submitting this complaint to ensure this issue is documented and reviewed, as transmission failure combined with an airbag warning presents a serious safety concern. Also, it's been widely documented by other consumers of having the same problem with the transmission failing prematurely on these type of vehicles as well.
Vehicle hesitating when attempting to accelerate. No power or minimal momentum when pressing on gas pedal. Transmission control module would randomly drop out and loose communication at the same time the body control module thought the vehicle was in park. It would lock and unlock the doors multiple times and the car would jerk uncontrollably. Extremely unsafe while mobile. Issue first occurred randomly summer of 2023 and has progressively gotten worse. Now it occurs at least once every 2 weeks.
Car keeps stalling and the service power steering warning comes on the dash as well as the service air bag. Then the car speed drops to around 20 mph and won't go any faster and then when you stop at a stop sign or something the car acts like it doesn't want to go
Engine is known for bad piston rings and a poor emission ventilation system causing extreme engine pressure, blowback, and oil consumption. Engine stalled due to NO oil in it. No oil warning light appeared. Almost ran over two pedestrians as my car would not brake quickly enough as there was no power to any of the systems. And now I have to pay well over $6,000 to repair it? I JUST had my oil changed 5 days ago.
I have included here copies of correspondence between myself and General Motors relating to an issue with my 2014 Buick Verano. As stated in the emails, after some online research, I found that there was actually a class action lawsuit pending in the court with regard to the issue I was having. I did reach out to the attorneys office handling the class action suit and received an auto-reply that they received my message, but nothing further. What I find very disturbing is that in one google search, I found...

multiple articles and forums as well as two class action lawsuits that address the very issue of excessive oil consumption and General Motors has not done anything to address this issue with vehicle owners. At the very least, a TSB should have been issued to make owners aware of this issue so they could address it properly. There continues to be many posts by people still experiencing this problem which is unacceptable. The issue has caused unnecessary wear and tear on my car and many costly repairs. My car continues to have issues that may have been caused by the initial PVC problem.
Newly purchased delivery of 2014 Buick Verano. from Auto Deal Makers in Chantilly, Va. Not even 5 miles driven, car was hesitant at 20mph, felt like it was going to stall out at 40mph, my left upper lip started tingling, my kids felt sick as we all experienced a heavy taste & smell of burnt oil in the cabin of the car. Two hours later my kids & I still could not get the taste of burnt oil off our tongues and back of our throats even after eating. Contacted GM & Chevy although they are fully aware of the defect...

they refuse to accept responsibility. The tingling has now reached my chin as though my children and I have been affected by some form of toxic chemical poisoning. This was the first time I ever drove my newly purchased vehicle, and have been poisoned myself & my kids by the toxic fumes the car is emitting. Total recalls should be done, and full compensation to consumers. GM & Chevy are fully aware of the defects and should be held responsible and accountable for the dangerously hazardous fumes that they are knowingly allowing unsuspecting consumers to become victims of their neglect and found guilty of all laws created to protect consumers, and the environment for these defective vehicles and found guilty pursuant to any and all Lemon Laws pertaining to aforementioned toxic chemical exposure. All of these makes/models that have similar issues should be recalled immediately for the safety and health of the consumers, and the environment.
Vehicle is consuming oil at an excessive rate (with still less than 70000 miles on the odometer) and I have had to keep a close watch on the levels. It is burning a quart right now about every 1400 miles and the problem is only likely to get worse with time. This could cause the engine to fail or catch fire while operating the vehicle, which is quite dangerous, especially at interstate speeds or on mountain roads. Buick has not issued a recall, and yet there is a service bulletin dating from 2016 (Bulletin No.:...

13-06-01-003H). I have also read many complaints from other Verano owners about this problem. An engine is one of the most expensive parts of any vehicle, and if Buick will not voluntarily recall this model year to make the needed repairs, the NTSB ought to take a hand in getting a recall of affected vehicles. I don't want to risk my life on the road if this engine fails while the vehicle is in operation.
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.
My Buick Verano keeps running out of oil despite consistent oil changes. It ran out of oil, 3000 miles before my next oil change was due. There are many reports online of other owners of the same vehicle having the same issue. Recently, my car cut off in the middle of the street Without any warning due to no oil in the engine. The low oil warning light never came on. This is the second time that this has occurred. The first time the mechanic just said it was low on oil. Now my car will not restart. Again my next oil change was not due for another 3000 miles.
My 2014 Buick Verano, that I have owned for several years now, is consuming oil at an alarming rate. The problem is that the manufacturer put a PCV valve into the engines intake manifold that gets clogged and produces too much pressure. With the pressure being so high, it forces oil into the air intake breather box and up through the throttle body and gets burnt off. If the oil pressure gets too high, the additional risk is that the rear main seal may get blown. Because of this, I have to continuously check for...

proper engine oil level, and even while doing that often (weekly), there are times that I find the car needing more than 2 quarts of oil to be put into the engine regardless of how long it has been between oil changes. Additionally, there has never been an oil light or any indicator light showing any trouble at all. GM knows there are problems with these 2.4l engines because they sent letters to some owners of 2012 GMC Terrains with the same problems. As there are still many Buick Veranos and other vehicles on the road sharing the same engine, I believe that GM should still be held responsible for repairing a known problem. I have not taken this to the dealer for this problem, as I have read many other accounts of people being charged diagnosis fees with $5000 plus repair bills for this issue.
The PCV orifice that is located inside the intake manifold is known to clog due to a manufacture defect, which then produces high pressure inside the crankcase. The pressure then forces high amounts of oil through the valve cover orifice into the intake breather box. The oil then fills up inside and get into the engine air filter and throttle body. The high amounts of oil being sucked into the intake will leave the engine running with zero oil, thousands of miles before a oil change is due. This would obviously...

destroy the engine if oil is not added regularly. There is also a high risk of the rear main seal blowing due to the high pressurization of the crankcase. This is a very known defect and without a question, needs to be issued as a recall.
The contact owns a 2013 Buick Verano. The contact stated that while operating the vehicle, there was a knocking sound coming from the engine. Upon inspection, it was the discovered that the engine oil level was extremely low, although the oil had recently been changed. The cause of the failure was not yet determined. The local dealer was notified of the failure, but no assistance was offered. The manufacturer was not contacted. The contact stated that there was an unknown TSB to address the failure. The failure mileage was 70,000.
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.
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.
