While I was driving the rear main seal went out and I lost all my oil. Luckily I was close to home, could have blown my motor. This is a $1500 to a $2500 fix. This happened around feb.26 2024 and my car is still sitting I'm my drive until I can save up the money to fix it. Also the few places I have called around to fix it have had other equinoxes in for the same thind,22 that I know of.

I was driving when my car started knocking. I pulled over on the highway and noticed oil all over the undercarriage of the vehicle. I immediately drove to the dealership and had the mechanics take a look. They came back and said, "The rear main seal was leaking due to a plugged PCV port that froze because of the cold weather. This caused high crankcase pressure to build, which blew out the rear main seal." Looking online, I found that this appears to be a common problem. The dealership said they could fix it by drilling the hole in the PCV port bigger, but there is currently no recall on this issue. Just to replace the seal, they are charging $2500, with an additional few hundred dollars to enlarge the PCV port. Thankfully, I was able to pull over and get it to the dealership. I can only imagine how bad things could have been if I hadn't been in a relatively safe spot.

My son was driving and all of a sudden the check engine light came on, it got really loud and stalled out while he was driving. Luckily he was on a road with a low speed limit. If this had happened on the highway it could have been extremely dangerous. He is a 16 year old new driver. We took it in and were told the rear main seal blew and we need a new engine. Apparently this is a know issue with this car. We are now in the process of installing a new engine on a car we have taken very good care of with less than 100,000 miles and still has a car payment. There were no prior warnings and the issue was confirmed by the dealer.

Car started to leak oil, took it for repair was told it has a pcv valve issue, that can lead to main seal failure. This is a 13 hour repair, at a cost of approximately $2500 This issue can happen again, and especially in cold weather. So even if you get it repaired this pcv/valve issue can cause main seal failure again. From Mechanic Report: -??Finding:.Other engine oil leak issue -??Recommendation: See technician notes below -??Technician's Notes: Rear main seal leaking. Lower oil pan very likely leaking as well. PCV system failing caused Excessive engine pressure which in turn caused rear main to fail. There is a GM TSB specifically for this issue. Without repairing PCV, seals will fail again. Repairing PCV system will require intake and valve cover removal. -??Full recommendation: -??-Remove valve cover and clean pcv passages -??-Remove intake, replace pcv valve, and clean pcv passages. -??-Replace rear main seal -??-Replace oil pan seal My vehicle mileage is Odometer 68,201mi so I am out of the warranty window.

Took the vehicle in due to poor function to be addressed and the vehicle was found to have no oil in the engine. 5 quarts of oil was just placed in the engine at the beginning of the week and was told that the engine is burning oil very badly. This is very concerning as I am seeing that other people are having this exact issue, often while driving on the highway. We are only driving this vehicle if absolutely necessary and do not have the money to replace the engine and the pistons. We have been diligent with frequent oil changes but we cannot keep pouring oil in this vehicle only for it to be gone within days or hours. This is a huge safety risk and could cause injury or death to myself, my children or others on the road. The check engine light came on after the oil was added. Took to our mechanic and they confirmed that the entire engine or at least all the pistons will need to be replaced in order to make this vehicle safe for driving. Called General Motors about this issue and was informed this very vehicle is in class-action lawsuit for the very same thing my vehicle is experiencing and that a recall should be coming out, but no one knows when this recall will come out. This is a common problem seen with the equinoxes and it needs to be fixed by the dealer or General Motors.

Cold weather here apparently caused the rear main seal to blow out and leak all of my oil out of the vehicle very quickly. Now I-??m left with a car that will not run, extended warranty will not cover. I-??ve read MANY stories of the same exact thing happening to equinoxes. If this is so common why is it not covered? I have 2 small children 6 and under and work full time. I cannot afford a new vehicle. So disappointing this is such a common problem yet not covered at all leaving people without a vehicle.

The PCV System froze causing the rear main seal to blow on my 2017 Chevrolet Equinox Premier. No prior warnings such as check engine light of any kind. In a matter of one minute I was driving 65 miles an hour on the highway to a warning popping up on my LCD screen stating "engine oil pressure low - shut down engine now". Didn't even have an opportunity to shut it down, within 30 seconds of that message the car shut itself down. This could have caused injury to myself and others but i was able to get to shoulder before total engine failure. This happened after several days of below 0 temperatures, snow and ice.

While in rush hour traffic in temperatures at 5 degrees or lower my car came up with a warning light of "Engine Power Reduced" as I proceeded to cross over to the right lane of the highway in order to pull onto the shoulder of the road the car lost all engine power. The car was towed to a Chevy dealer for assessment of "rear seal blown causing oil leak and ruining the engine causing needed replacement" My safety & that of other vehicles around me were in danger from the engine power going from 55 to 0 in moments in rush hour traffic in extreme temperatures. The car was assessed by the repair shop & our auto insurance.

Our temperature recently dropped below zero temps. Our PCV system froze which caused an obstruction. This caused the crankcase to pressurize blowing out the seals, losing all oil, and catastrophic engine failure. Our safety could have been impacted as we live in a rural community with subzero temps. Being stranded without service on a phone or vehicle to stay warm could have catastrophic consequences on human life. Losing engine power on a busy road could lead to a crash etc. The problem was confirmed by the dealer. This is a known issue in 2.4L engines as seen in bulletin 14882 from March 2015. The vehicle was inspected by the GM dealership in our town who confirmed this was the issue. There was no warning prior to the failure- the incident happened while driving home from work- at the time of failure the stabiltrak and reduced engine power came on.

The contact's daughter owns a 2017 Chevrolet Equinox. The contact stated that while his daughter was driving at various speeds, there was an abnormal grinding sound coming from the vehicle. There was no warning light illuminated. The contact's daughter inspected the vehicle and discovered that there was no oil in the engine on the dipstick. The contact inspected the vehicle and discovered that the PCV (Positive Crankcase Ventilation) valve was clogged due to moisture buildup, which caused the crank case to fail. The dealer was notified of the failure and provided an estimate for a new engine. The manufacturer was also notified of the failure but offered no assistance. The contact was referred to the NHTSA Hotline for assistance. The vehicle was not repaired. The failure mileage was approximately 96,000.

When I was driving the vehicle, the dash said low pressure oil turn car off. Not even enough time to find a place to pull over. It just shuts off. Had been going 55 instead of 35. I could-??ve gotten rear-ended with it just shutting off talk to a Car repair shop and they said those are all starting to do that the rear main seal blowing out. They didn-??t have a big enough hole in the intake and it-??s plugging up and building pressure and blowing the rear main seal.
