2014 Chevrolet Equinox: misfire or rough idle

Filed Jul 29, 2026 · Engine · IA

Component Failure & Availability: A GM remanufactured 2.4L engine block, installed as a replacement in July 2025, suffered a catastrophic internal failure (blown head gasket) within 11 months of installation. The vehicle and the component are currently in the owner's possession and are available for inspection upon request. Safety Risk: A blown head gasket with an internal coolant leak into Cylinder #3 causes immediate engine overheating, severe engine misfires, and a loss of motive power. If this defect causes the engine to stall while the vehicle is in motion, the driver suddenly loses power steering and acceleration, directly compromising the safe operation of the vehicle in traffic. Confirmation by Service Centers: The catastrophic failure was formally reproduced, pressure-tested, and confirmed by an independent service center. Inspection by Manufacturer/Others: Following the independent confirmation, the vehicle was inspected by an authorized manufacturer dealership. During this inspection, the authorized dealership executed an unauthorized teardown of the engine block and sublet the engine head to a third-party machine shop, physically altering the failed component prior to manufacturer review. Warning Lamps & Symptoms: A check engine light illuminated shortly after the engine's initial installation. The authorized dealership evaluated the vehicle, reset the diagnostic trouble codes (DTCs), and released the vehicle back onto the roadway without properly diagnosing the warranted engine block. This allowed a defective and degrading powertrain component to remain in operation until failure occurred.

The most noticeable things wrong are the RPMs and the oil consumption. The RMPs fluctuate at idle, hinting at a misfiring of the pistons, which you can hear when it sits at idle. The second thing is I top off the oil with a quart of oil every gas fill up. The engine light keeps popping on even after engine repairs are done. The exhaust manifold and catalytic converter had to be fixed and that didn't solve the problem. The pistons' psi was tested and one piston had a psi of 70 while the other 3 tested to 125 psi. This is low for all the pistons with a possible broken seal on the one or something else. Chevy recommended 7500 miles between oil changes, but it should be 3000 to 5000. I think in the car's early life, oil changes were not as frequent as they should have been causing damage to the engine that is showing problems now. Having to add a quart of oil at every gas fill up can cause serious damage to the engine and other parts of the car as well, and already has. I will attach a recent repair at Chevy and screenshots of what Google said Chevy recommended for these cars at first. Now realizing that 7500 miles is more than twice as long as it should be for an oil change, Chevy will say 3,000-5,000 for an oil change. But now the range is 3,000 to 7,500. This is not reliable information for these cars. I don't trust my vehicle to go over 3,000 miles due to the oil consumption. The RPMs still fluctuate and the engine light came back on. I suspect something deeper in the engine is wrong, which if it is not fixed, more damage to the engine and car is inevitable.

Oil consumption issue with no warning and no indicator lights. I get regular oil changes and was never told I was ever low on oil. Engine was running with no oil and cause pistons to misfire and vehicle began stalling with my young children in the vehicle. Piston damage has caused metal shavings to enter engine and engine now needs to be replaced with 61,000 miles on the vehicle. My safety and my children’s safety was risked with no warning and no indication there was any issue, which could have resulted in an engine fire. Two different repair shops said this is a common issue with the equinox and has been involved in class action lawsuits in other states for models 2008-2017. I have called the dealership which resold the vehicle to me used knowing there was an issue and didn’t disclose any information regarding this and they have refused to do anything for me except for so the repairs and have me pay out of pocket because they say there is no issue large enough for a recall.

Got oil changed regularly in the car only to have my engine misfiring a month after having my oil changed. Took it in to get looked at and they told me there was next to no oil in the car and that my car was burning extra oil and that I was going to need a new engine. After one google search I have come to find that this problem is not uncommon and that there was a class action lawsuit, but only went up to year 2013, even though the issue did not stop with the 2013s.

My car runs rough and shuts off when slowing down or stopping at stop signs and red lights. My car has 112,000 miles and warranty ran out at 100,000. Check engine light code is p0010. This seems to be a very big problem for the equinox and there are no recalls. The older models have recalls for the same issue. I feel this is a very dangerous issue that cheverlet should take responsibility for.

Purchased a 2014 chevrolet equinox 2.4l engine back in late 2013 prior to a deployment. After years of no major issues the car began consuming more oil considerably after 115,000 miles. Shortly after this issue began there was rough idling with the service engine light coming on. After taking the car in for inspection it was found that a common issue regarding the timing chain was affecting the car. The timing chain came loose shortly after the service engine light and had rendered the engine unusable. On the drive to the mechanic there was also multiple stalls of the engine which posed a serious safety concern. After hearing from multiple others this is a common issue with the 2.4l ecotec engine.
