Vehicle has serious oil consumption issues. Will burn as much as 3 or more quarts in 1000 miles or less. Was notified by chevrolet mechanic that some oil consumption was normal, but that if the consumption was excessive that I would have to pay up to $3500 or more to fix the car. There isn't a recall out on this make and model, but all cars equipped with this 2.4l ecotech engine had the same issues from the research I conducted. The mechanic I talked to said that this was a known issue due to a defect in the piston rings allowing oil to reach the combustion chamber. Sometimes even the fumes come into the car and they are pretty harsh to breathe in.

Called local dealership for a few recalls,they said they had to order the parts for recalls so when they got the parts they called and set me a time to get them fixed well when I got there they said that it only had 1 recall and they had to order the part that was already supposed to have been ordered to began with and they would call when they get the part in "still waiting on that call" the vehicle has 97000 miles and is also burning oil fast and smoking out the exhaust,they said it was out of warranty and there is no recall on the engine oil consumption on this vehicle because its VIN specific so the bill would be on me to have the engine tore down to see what is causing it to burn oil but I no it's because of premature wear of the piston rings after the research I have done on these engines so far but what ever the case they have yet to call me back and it's been almost 2 months now not sure what to do at this point.

My 2011 buick regal with the 2.4l 4cyl has been excessively consuming oil. The timing chain was replaced around 60k miles, and shortly after the complete engine was replaced (see carfax image attached, confirmed with dealer). Those repairs have happened before I owned this vehicle. My concern is that there is going to be a failure within my engine and the repairs would be costly to me. I believe this issue needs to be looked into as it's been a common issue with these engines. The vehicle is now at 159k miles and I've been adding a quart or more of oil between changes.

Reference the below background information on gm's l4 - 2.4l 4 cylinder engines: please reference document id: 4821148 #12313d: special coverage - engine balance chain and fuel pump - (june 6, 2017) this special coverage bulletin was provided by my mechanic at midas from the http://alldatapro.com website. Special extended warranty repairs are supposed to be covered via this bulletin for 120,000 miles or 10 years for gm vehicles that have the l4 engine including the 2011 buick regal. My 2011 buick regal is definitely exhibiting all symptoms / problems that are well known with the general motors l4 - 2.4 l four cylinder engine. See information below about oil consumption and engine performance symptoms: https://www.msn.com/en-us/autos/research/seven-engines-to-avoid-like-the-plague/ar-aavz7vm#page=3 I am a former gm powertrain division engineering / salaried employee where I had a 20 year career background with engines and transmissions. The l4-2.4l engine is a known safety hazard as the engine can fail while under normal operation on a highway or city street with potential catastrophic results. Even with the mechanic oe bulletin referenced above, gm refuses to cover expenses for permanent repairs for the 2011 buick regal. Instead dealership customer service representatives are instructing vehicle owners to just add oil frequently. (note: the low oil indicator is also defective.) please also reference the class action law suit below: https://www.classaction.org/media/berman-et-al-v-general-motors-llc-joint-notice-of-settlement.pdf gm corporation customer service, professional mechanics, and gm's dealership network (buick and cadillac) all are fully aware of the catastrophic safety consequences that this engine poses to the general public; yet, a comprehensive recall and appropriate extended warranty coverage is being denied.
