2016 CHEVROLET EQUINOX Complaints

In February of 2025, while driving my 2016 Chevy Equinox home from work, I heard a loud pop and loss of engine power a block from home. The weather conditions at the time were below freezing and light snow. After getting my vehicle home, my neighbor, who works for GM looked under my Equinox and discovered the rear main oil seal had blown and informed me this was a known issue with the GM 2.4L Ecotec engine. The GM 2.4L Ecotec engine contains a non-serviceable Positive Crankcase Ventilation (PCV) system that uses a fixed orifice built into the intake manifold instead of a replaceable PCV valve. In cold weather, moisture and vapor inside the crankcase can freeze or accumulate as sludge within this orifice. When the orifice becomes obstructed, the PCV system can no longer vent crankcase gases properly, causing internal pressure to rise significantly. This condition is most common in sub-freezing temperatures and is documented in multiple GM technical bulletins. When crankcase pressure increases beyond normal operating limits, the pressure seeks the weakest escape point, which is often the rear main seal. As pressure builds, the rear main seal can rupture suddenly, resulting in an immediate and severe oil leak. This failure can occur without warning and may lead to rapid oil loss, environmental contamination, and potential engine damage if the vehicle continues to operate. The defect is inherent to the PCV system design and is not related to owner maintenance practices. General Motors has been aware of PCV system obstruction issues in the 2.4L Ecotec engine since at least 2013, when internal service bulletins first documented rear main seal failures caused by crankcase over-pressurization in cold weather. GM issued additional bulletins in 2014, 2016, and 2019, each reiterating the same failure mechanism. In 2014, GM created Special Coverage Adjustment 14882 but many vehicles equipped with the same engine and PCV design were not added, including mine.

: "I live in my car. The 2016 Equinox 2.4L burned all its oil in 2 weeks with no leaks, failed to give a dashboard warning, and the engine is now knocking, threatening to leave me unsheltered." This ties my vehicle's specific failure to the federal database for future legal payouts.

I started up my car on a cold winter morning and I heard a loud popping noise. I backed up my car minutes later and discovered puddles of oil in front of me in my driveway. I asked my husband to come out and look. He got under the car and said my oil blew out of the rear seal. I was unable to drive my car as the seal was blown. After some investigating I discovered it was the PCV valve that froze and blew out the rear seal. I discovered that Basil Ford was sent this Bulletin and told to clean the PCV valve when people brought their car in. They never reached out and told me to bring the car in to have this done. It could have been an easy fix. I also discovered by researching that people had this happen to them when they were driving on the highway and it caused them accidents. I called GMC and they are telling me my 2016 isn't in the class action suit. Basil wanted way too much money so I took it to Pep Boys and it cost me $3,000 to have the PCV valve replaced with the kit that prevents it from freezing up again and I had to replace my manifold and my rear seal

Around 100,000 miles car started burning through oil. Have to check oil weekly. No warning lights come up when the oil is low. Patiently waiting for them to put a recall on it.

Excessive oil consumption with no warning light, loss of power, and stalling. Also caused the master seal to leak and plugged the PCV valve. I have records for the repairs. It continues to excessively use oil and is not a reliable vehicle. When it stalls, power steering is lost as well as the stabilitrack.

Engine failure. There is a class action that has been filed for this exact make, model, and engine size. There were no lights indicating an issue and the car had recently been serviced with an oil change and oil filter change and was being regularly maintained on oil changes. When it was brought to a mechanic, they told me the entire engine had failed and there was no power to one of the spark plugs anymore. I reached out to GM regarding this and they acknowledged the failure

Transfer case and front differential failure. No warning lights came on beforehand

The contact owns a 2016 Chevrolet Equinox. The contact stated that while reversing the vehicle on a cold, snowy day, there was oil on the driveway. There was a fuel odor inside the vehicle, and the engine warning light was illuminated. The vehicle was towed to an independent mechanic, who determined that the failure was related to the PCV system. The mechanic stated that the PCV valve was clogged, causing the gasket to fail. The vehicle was partially repaired. The mechanic later informed the contact that other repairs were necessary. The local dealer was contacted and confirmed that there were no recalls associated with the failure. The vehicle was not diagnosed or repaired by the dealer. The manufacturer was contacted and confirmed that there was no recall coverage associated with the VIN for the repair. The contact was referred to the NHTSA Hotline for assistance. The failure mileage was approximately 113,000.

I am writing to formally document a series of catastrophic mechanical failures regarding the aforementioned vehicle. Despite rigorous maintenance and significant financial investment, the car remains non-drivable, posing a severe safety risk. Chronology of Failures: October 2024: Four months post-purchase, the timing chain failed on I-94. Atwater Chevrolet replaced the component; however, this did not resolve the underlying engine instability. December 3, 2025: Following a dashboard warning light, a Northland Chevrolet dealer replaced the solenoids. At this time, the windshield wiper motor also required replacement. Late December 2025: Shortly after these repairs, the vehicle suffered a major failure of the rear main seal and engine block during sub-freezing temperatures. This caused a total loss of oil and left the driver stranded in hazardous conditions. Maintenance and Disclosure: We have invested over $4,000 in preventative maintenance, including oil changes every 2,800 miles to mitigate known oil consumption issues. At the time of sale, there was no disclosure regarding the inherent engine defects common to this model. Current Status: The vehicle is currently at a dealership and is inoperable. A $10,000 loan balance remains. Current diagnostics suggest a frost plug failure triggered the event. I have contacted GM regarding Bulletin 14882, which addresses identical issues in similar models, but was informed it does not currently attach to this VIN. Furthermore, the extended warranty provider has denied the claim following an inspection, despite the documented manufacturing issues known to affect these engines for several years.

The wiper blade motor is gone out. The tire pressure sensor is off : the oil seems to disappear faster than the sensor
