2017 Chevrolet Equinox

My 2017 Chevy Equinox, equipped with the 2.4L Ecotec engine, experienced a catastrophic failure due to a faulty PCV system. In cold weather, condensation caused the PCV valve to malfunction, leading to excessive pressure and ultimately blowing out the rear main seal. This issue has been well-documented in the 2010–2013 models, which were covered under a class-action lawsuit, but the same defect persists in later models, including mine, which are not covered. This design flaw creates a significant safety and financial burden for owners and needs further investigation.

On 1/5/25, the rear main seal ruptured due to a known issue in the vehicle's PVC system, causing severe oil loss, potential catastrophic damage to the engine, loss of power, possible accident and/or injury. The problem was confirmed by a local Chevrolet dealer, with an estimated repair cost of $4000. The failure occurred without any vehicle warning lights activating.

The contact owns a 2017 Chevrolet Equinox. The contact stated while driving 65 MPH, the vehicle suddenly went into LIMP Mode. The traction control, the stability-track warning lights, and several other unknown warning lights were illuminated. The contact was able to pull over to the side of the road. The contact stated that upon restarting the vehicle, the low oil pressure warning light illuminated. The vehicle was towed to The Race Car Factory, where it was diagnosed that the engine's rear main seal was blown. The mechanic determined that the rear main seal needed to be replaced. The vehicle was not repaired. The dealer was not notified of the failure. The manufacturer was notified of the failure and informed the contact that the VIN was not under recall. The manufacturer provided no further assistance. The failure mileage was approximately 147,000. The VIN was not available.

When I was exiting the expressway, my car suddenly stopped without any warning. I managed to restart it, but after driving just a few feet, it stalled again. I was able to restart it once more, but this time I could hear a knocking noise coming from the engine. I initially thought it couldn't need oil since I had an oil change just the previous week. I drove to a nearby gas station to check the oil level, and although the oil gauge indicated 91%, I found there was no oil in the engine. I added two quarts to get a few blocks to my destination. However, I soon noticed oil leaking out. I decided to have my car towed to a Chevy dealership, where I was informed that I had a blown rear main seal caused by a faulty PCV system. I was told that this situation was dangerous, especially since it occurred on the expressway. The repair cost over $3,000. I contacted GM to see if they could assist me with cost but was told only after I got the issue fixed they wouldsee what they could do. I've also noticed that many other 2017 Chevy Equinox owners have reported similar problems online. Could you please look into this?

I am having this same issue with my 2017 Equinox as stated in the below information. It currently only has 58390 miles. I have already paid over 700 to try and fix and now they are telling me it is going to be another $5040.00.I feel like this should be covered by the class action lawsuit. The lawsuits against General Motors allege that the 2.4-liter EcoTech engines found in model year 2010-2017 Chevy Equinox and GMC Terrain SUVs burn excessive amounts of oil. The safety risk posed by the apparent defect is substantial, the lawsuits claim, given that an engine operating without sufficient oil could wear down and fail prematurely, even during the course of normal operation, due to friction. According to the lawsuits, General Motors, for its part, actively concealed from consumers that its Equinox and Terrain vehicles suffered from an oil consumption defect. Worse, the suits say, GM allegedly failed to offer vehicle owners and lessees any help by way of repairs or recalls.

Oil leak caused by insufficient ventilation and excessive oil burning caused rear main seal and timing chain belts to fail. Oil warning systems were too late in warning about problem until engine stalled out and all oil was consumed, causing engine failure. No low oil warnings came up until minutes after the initial engine shutdown. Research has shown that this has been a known chevy problem since 2017, with a recall being issued earlier on but no known recall now. Dealer has confirmed issues and also that the engine design is flawed and leads to oil burning excessively

Majority of the oil leaked out of the vehicle, the low oil light never came on. Car was towed to the shop after I was told not to drive it, as the engine will most likely seize up. The shop found that the rear main crankshaft seal was blown out and leaking to access crank case pressure due to a PCV orifice plugged, not letting the engine vent.

The contact stated that there was a loud sound coming from the exhaust and there were exhaust fumes entering the cabin of the vehicle while starting the vehicle. The vehicle was not taken to an independent mechanic to be diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 144,000.
