2014 Chevrolet Equinox Complaints

The contact owns a 2014 Chevrolet Equinox. The contact stated that while driving at various speeds, the vehicle made an abnormally loud sound, shuddered, and stalled. The check engine warning light was illuminated. The contact was able to pull over to the side of the road on several occasions. The vehicle was taken to an independent mechanic, where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The engine had been replaced approximately two years prior due to a similar failure. The manufacturer was not notified of the failure. The failure mileage was approximately 100,000.

Engine went into limp mode with now warning. I recieved a reduced engine power warning and the vehicle lost acceleration on the highway almost leading to an accident. I had the car towed to Coggin GM for diagnostic and was told that my throttle body has to be replaced. I was advised that this is common issue with this engine and notify due to a recall of older equinoxes

Safety Complaint – Sudden Oil Loss and Engine Failure – 2014 Chevy Equinox Hello, I am reporting a serious safety issue involving my 2014 Chevrolet Equinox with the 2.4L Ecotec engine. My vehicle began consuming oil at an abnormal rate without any dashboard warnings in early 2025. The oil level would drop dangerously low between regular oil changes, and the problem escalated quickly. I had to carry oil and a funnel at all times to avoid engine damage. Despite proper maintenance, the engine failed and required replacement on March 27, 2025, at a cost of $11,879.28. The replacement engine includes a 3‑year or 100,000‑mile warranty, but it is the same Ecotec design. Approximately one month after the replacement engine was installed, I experienced another incident requiring service. This occurred despite the engine being brand new and under warranty, raising concerns that the defect may still be present and that the vehicle may remain at risk of sudden failure. This sudden oil loss...

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 re...
