Car uses excessive amount of oil! We have had the timing replaced and now it’s stating the P0420 catalyst system efficiency below threshold bank 1.
According to our mechanic, our vehicle’s PCV system became clogged and it increased the pressure in our engine and caused the car’s rear main seal to rupture, leading to catastrophic oil loss, loss of power to the vehicle, and engine damage. In our case the entire engine needed to be replaced.
The 2015 Chevrolet Equinox equipped with the 2.4L Ecotec engine has been reported to have excessive oil consumption due to several issues: Defective Piston Rings: The oil control rings are prone to sticking and clogging, leading to oil blowby and excessive consumption. PCV System Issues: Problems with the Positive Crankcase Ventilation (PCV) system can create excessive vacuum in the crankcase, contributing to oil consumption. Timing Chain Problems: The timing chain can stretch over time, leading to misalignment and potential engine damage. Regular Maintenance: Owners are advised to monitor oil levels frequently and consider using synthetic oil for better performance and longevity. These issues can lead to significant engine wear if not addressed promptly. My vehicle is using too much oil. The 2.4L eco tec engine is installed in this vehicle. The Chevrolet dealership in Rockwall Texas texted me that the engine is bad and needs replacing. The vehicle is past is warranty, so the dealership is using that reason, to not fix this issue. The estimated cost to replace the engine is approximately $11000.00.
The 2.4 liter engine in my car has had excessive oil consumption. now the engine oil is like peanut butter and the blow by out the oil fill is strong.
My daughter, the driver of this vehicle, noticed a noise. The check engine light came on. Over a short period, the noise from the engine progressively worsened. We brought the car to a certified mechanic. The mechanic's initial determination was that the engine would need to be replaced. It was determined that the engine was faulty, failing due to oil leakage that led to excessive oil consumption. As we were not ready to make that kind of financial commitment, we asked him if there was another option. We were instructed to check the oil frequently. We did so over the next couple of months, but the problem continued and worsened. As my daughter was driving, the engine would make a noise and lose power. Eventually, the vehicle started shaking and would shut down when stopped at red lights and stop signs, requiring the engine to be restarted each time. We then brought it back to the mechanic, and the engine was replaced with a new one.
Timing chain tensioner lost tension and timing chain got so loose it would not turn the cams and catastrophic engine valve damage was done! This engine is notorious for this and there are class action lawsuits as a result but no recalls from GM as yet only TSB’s (Technician Service Bulletins). This is going to cost me thousands in repairs and I still owe $8500 on it. If this happens in traffic it could pose a serious safety risk in addition to the financial burden it is causing many people! Mine fortunately happened in my driveway and the vehicle had to be towed to my mechanic and has been there for 3 weeks. Have had rental vehicle costs as well. He had 3 other 2010-‘16 GM 4 cylinder 2.4L Ecotec engines in his small shop with the exact same issue! After doing research it is a common issue and GM has done nothing to solve it!
Noticed knocking in the engine and excessive oil usage. I keep my vehicle maintained. I went and had the values and seals replaced around engine for oil. Not even two to three weeks later knocking again. Took it back and engine is burning oil. Read about this make and model having defective pistons and rings causing oil to burn excessively. This has cost me thousands of dollars and it's still not fixed.
The timing chain went down i only have 95000 miles on it is heard these timing chains went down on. Certain equinox i feel this should of been on a recall since chevy knew this was happening 3 000 dollars later

On [XXX], I was en route to Montgomery, Alabama, from Canton, Georgia, driving my 2015 Chevrolet Equinox on the highway at approximately 55 miles per hour. Suddenly, my truck began to decelerate rapidly on its own. A warning message appeared on my dashboard stating, “Engine reduced power to protect the engine.” I had to skillfully steer my truck over to the right shoulder to avoid a potential accident and escape the flow of traffic. It was extremely perilous to be on the highway as my truck nearly came to a complete stop. I had to have my truck towed to Chevrolet in Montgomery, Alabama. In addition, I had to get an uber because my truck would not start at all. I had to spend money on ubers and a hotel.

I have contacted GM numerous times about excessive oil consumption in my vehicle. Even with pristine maintenance and making sure that the oil is changed when it needs to be, it is chugging oil. You can’t even drive 200 miles and it’ll be bone dry. Yesterday while I was driving, it stalled out in traffic and almost caused an accident! We were on an extremely busy highway and it just stalled right there! Thank God, the people behind us weren’t tailgating!! I have contacted GM numerous times. There is currently a class action lawsuit because a lot of of the Chevy equinox is burn excessive oil. There was a previous class action lawsuit on older Chevy equinox that was settled. It’s the piston rings and everything that are causing this issue. We’ve also had the previous recall fixed, but for some reason, they will not take it off of our vehicle!! The wiper blades were fixed and we’ve contacted numerous times about that getting corrected as well
I took my vehicle to a Chevy dealership due to engine light coming on with the stability track light showing as well as "reduced engine power notification. They are saying the timing chain is needing replaced therefore requiring the entire engine to be replaced. Vehicle is available upon inspection. Once the engine light came on and the reduced engine power light came on vehicle started stalling in traffic. I was at a traffic light and the vehicle cut itself off once I came to a slow stop. Vehicle had to be turned off and back on. Vehicle also started losing power while driving when trying to pull over to incident. Yes. I took my vehicle to a dealership. Initially, they changed other parts on the vehicle. However, when they tested vehicle, it was still showing same signs. That is when they came up with needing a whole new engine based on the timing chain. Dealership will not replace timing chain and states the entire engine needs replaced. Vehicle has only been inspected by a Chevy Dealer. Yes, Once the engine light came on, the stability track and reduced engine power mode came on. they first appeared about a week before i took the car in. I made an appt as soon as the lights came on. The dealership was not available for immediate assistance.
Oil issues. The oil light does not come on when there is low oil and the rear main seal busted and the car started to shake and then it turned off. No oil light or check engine light came on. The car did start back up and I was able to move it to safely. There has been several known issues with this model and engine. There is a current service bulletin 14882. However my 2015 equinox is not included in the service bulletin even though it is a known issue with models from 2010 to 2015. Thank You!
Excessive oil consumption leading to a broken engine
the 2015 equinox has been serviced and maintenance regularly. The engine's timing chain failed at 73k miles. No explanation on why. I was told even though I do maintenance regularly, it just happens in these vehicle. i now need a new engine not under warranty
Rear crankshaft seal has failed. Engin oil has blown out at bottom of engine and all over underside of car. Oil has covered the exhaust system causing smoke in and outside of car. Leaked engine oil could have ignited and caused a fire that would have consumed the entire car. There appears to be numerous postings on the internet of other chevy equinox owners with the same problem. There was no prior warning that the crankshaft oil seal was in the process of failure. I personally checked the oil pan drain plug and the oil filter cap, and these were not the issue of the oil leak. Again, from my investigation on the internet sites, it appears to be a common issue with the General Motors 2.4 Liter Vortec engine in the Chevrolet equinox car model. This issue can and probably result in total engine failure and need of engine replacement. The repair to replace the rear crankshaft oil seal is very costly and should not be needed on any vehicle with normal wear and use. With my internet investigation there appears to be a design problem with the PCV design and system. The PCV system is prone to clogging and freeze up in cold weather. This can result in excessive internal engine pressure the is a major cause of blowout of the crack shaft oil seal. The temperature at the night before was only 9 degrees. The car was last used under freezing conditions which could have contributed to engine failure.
AS I WAS DRIVING, AN ERROR CAME ON MY DASHBOARD STATING, "REDUCED ENGINE POWER". THE FASTEST I COULD DRIVE WAS 25 MPH, THEN YOU COULDN'T DRIVE AT ALL. I TOOK THE VECHILE TO THE MECHANIC AND HE STATED THE PROBLEM WAS A FAULTY OIL PUMP AND MOTOR.
To Whom It May Concern, I am writing to formally file a complaint regarding my 2015 Chevrolet Equinox, which I purchased used approximately one year ago. Since acquiring the vehicle, I have experienced severe and excessive oil consumption as well as ongoing fuel injector problems. Specifically, the vehicle requires additional oil every 100 to 200 miles, which is far beyond what is considered normal or acceptable for a properly functioning engine. I have not noticed any external oil leaks, and there are no warning indicators until the oil levels are dangerously low. This not only puts the engine at risk of damage, but also presents a potential safety hazard while driving. In addition to the oil issue, I have experienced fuel injector malfunctions which affect the car’s performance and reliability. This has resulted in rough idling, reduced fuel efficiency, and difficulty accelerating at times. I have come to learn that many other owners of the 2015 Chevy Equinox are reporting the same issues, particularly with excessive oil consumption related to engine design flaws. I believe this is a manufacturing defect that should be addressed by GM and reported as a recall or service campaign due to its widespread impact and potential risk to drivers. I respectfully request that the NHTSA investigate this matter further to determine whether a recall is warranted and to encourage General Motors to take responsibility for this recurring issue. Thank you for your time and attention to this matter. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
