What owners say
Engine used oil with no smoke or leaks. Had to change oil every 2300 miles. Motor went bad do to no oil even after oil change.
The oil consumption in the car is horrible, I have to atleat add oil in my car about 5 time in between oil changes, and my oil changes are done regularly, ive also have the issue of my oil and gas mixing, I did take it to the shop once and they fixed a recall that was involved with high pressure fuel pump, but im guessing they didnt fix the issue once that repair was done like they said it would.
Burning oil on a 2.4l equinox engine
Excessive engine oil consumption
The 2012 buick regal consumes a quart or more of oil in less than 2 weeks or 300 miles. I am putting a quart in it just to get it to read on the dip stick and more if needed. As it consumes oil, the engine gains a noticable ticking noise with a rough start. All of this is noticed while driving on a highway or rural road. The back right tire and or tire area makes a thumping noise at all speeds. The tire is not the issue. The stabilitrak warning light comes on often . I am the 3rd owner to the car with with 164,333 current miles. The car has had routine oil changes etc by all owners.
Engine timing failure due to faulty chain tensioner at 81000 miles (2/15/2020) engine consumes excessive amounts of oil between changes
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.
