1 Crankcase (pcv) problem

Failure Date: 01/27/2026

On 1/27/26, while driving at highway speeds, I received a "reduced engine power" alert. I was forced to pull over immediately; the vehicle stalled before I could reach a complete stop. This left me stranded in dangerously cold temperatures for an extended period while awaiting a tow. Upon inspection, I was informed that the engine has failed and requires a complete replacement. This is highly distressing for several reasons: * low mileage: the vehicle has only 54,000 miles and is well under the expected lifespan of a modern engine. * meticulous maintenance: as a loyal customer, I have had every scheduled oil change and service performed at my local Chevrolet dealership. My service history will confirm that this vehicle has been maintained to the highest standards. * brand loyalty: I have been a dedicated Chevrolet owner for years, having purchased five brand-new vehicles from your dealerships. I chose Chevrolet based on a reputation for reliability that, in this instance, has not been met. "I am specifically concerned because my vehicle's symptoms align with special coverage adjustment #14882 (pcv icing). Given that the failure occurred during extreme cold and resulted in immediate engine failure, it appears to be the exact scenario outlined in your technical service bulletins regarding the 2. 4l engine. I am requesting that this repair be handled under that special coverage or a similar goodwill extension. " my research indicates that this specific engine model has a documented history of similar issues. Given my history with the brand and the premature nature of this failure, I am requesting that Chevrolet review my case for a goodwill repair adjustment or a significant cost-sharing assistance for the engine replacement.

2017 Chevrolet Equinox lt with a 2. 4l ecotec engine. The pcv system froze due to the cold weather conditions caused the rear main seal to blow futher causing cylinder scoring to the engine. I got it checked out by a local mechanic that actually works with the extended warranty company called silverrock that's provided from the dealership drivetime from who I financed the truck from. The mechanic shop name is hoekstra muffler and alignment located at 722 w 151st st, east chicago, in 46312. They were the ones to diagnose the problem and provided me with a diagnostic sheet for this issue. The vehicle has not been checked by a Chevrolet technician yet. I took the truck in for a regular maintenance oil change on January 8th at walmart in portage, indiana. My truck was driving fine and suddenly on January 20th my truck seized on the highway on my way to work at 7am. A warning light marking low oil pressure turn off engine was marking on my dashboard. After I was in a safe spot on the side of the expressway, I have life360 and proceeded to call for a tow truck. When the tow truck driver arrived in order to put the car in neutral he has to jump start my Equinox. My truck will only start if it's jumped and keep the cables connected, otherwise it shuts off.

4 Crankcase (pcv) problem

Failure Date: 03/06/2025

After very cold winter weather, car started to smell. Pcv valve blew and car was seizing causing it to blow out the rear systems. It had spilled oil onto the garage floor and had a bad emissions smell. Dealership said they added 3 quarts of oil and that within 30 minutes two quarts leaked out. No warning lights on dashboard, no affected cautions through the Equinox app (which still shows that I have 80% of my oil still remaining). While driving the car started making a ticking sound during acceleration and a bad smell. I am now left with a $3700 bill. Numerous others have detailed exact experiences with their Equinox after the last February, cold spell in chicagoland. I was very fearful driving the car and my safety was compromised. The car was shaking, and the smell was pungent right now my car is at the dealership so I do not have the invoice.

5 Crankcase (pcv) problem

Failure Date: 02/20/2025

My vehicle had a pool of oil beneath it and a trail behind it due to a faulty pcv. I had it towed to the certified dealer and they told me it was a pcv valve issue, due to the cold temperatures, ice was able to accumulate and caused a pressure build up inside of the hose or something of the sort. With that being said, the pressure caused the seal to pop off and allowed for the oil to leak out and get all over the engine/parts within the engine. The dealership let me know they were aware and had correspondence about this particular issue. There was no sound prior to the decline of my engine, no indicator on the dash, and this issue can happen so quickly that there's no time to respond or reverse damage that was made. My engine no longer works and was told I would need to purchase a new one, despite the fact this issue could happen again with a new engine regardless of routine upkeep. Dealership confirmed the engine was damaged, the oil was depleted, and the pcv was to blame. There were no warning signs, it happened quite quickly, and I fear that if this incident didn't happen at night, my vehicle would have slowed or completely stopped at a rate that would have prevented other drivers from steering clear of me and harming themselves or me. Thankfully it wasn't a busy night. I was going 80km/hr and my vehicle slowed to barely 30 km/hr without being able to accelerate. At home, the engine shut down, and again a pool of oil was found before being towed to the certified dealership I had my routine inspection done at a few months prior. Vehicle previously register in texas, now resides in canada where incident occurred.

6 Crankcase (pcv) problem

Failure Date: 02/19/2025

Pcv valve got clogged and failed, I have an extended warranty and the extended warranty excludes this from any repairs if this is involved. Caused my rear main seal to break and leak oil. Not drivable currently. Quoted 3200 on a repair. Purchased the vehicle less than 12 months ago.

7 Crankcase (pcv) problem

Failure Date: 01/31/2025

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. My car shut off several times while driving in heavy traffic. I was in the car with my 6 year old child taking him to school on a busy street. This could have been catastrophic. In addition, I was informed my engine is burning oil excessively which is also a known issue. The safety risk posed by the defect, readily know by service techs, 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. My oil warning systems never detected the low oil. 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.

But since the pcv valve caused it , they didn’t cover that either. This repair cost me $2800. 00. Living on social security that’s a lot of money. I have called chevy, the dealer and the warranty CO to no avail, I have read about all the class action suits. This is a very serious problem. The bulletin states below 0 temperatures can cause this, we live in tennessee, we don’t have that kind of weather. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

10 Crankcase (pcv) problem

Failure Date: 01/20/2025

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?.

Due to the failure, the vehicle was towed to an independent mechanic where a diagnostic test was performed; however, the mechanic could not determine the cause of the failure. The vehicle was towed to the residence. The dealer was notified of the failure and the contact was informed that the pcv valve had frozen due to the cold weather. The contact was informed that the failure then pressurized the crank case valve and blew the engine oil seal. The contact was also informed that the timing chain had failed and caused the failure.

13 Crankcase (pcv) problem

Failure Date: 01/08/2025

The pcv valve froze last week causing pressure to build up and blew the rear seal. All the oil leaked out and caused a grinding noise and the vehicle shutoff on its own. This I have seen is an ongoing problem with the chevy Equinox. I was quoted $3800 from the dealer to repair.

14 Crankcase (pcv) problem

Failure Date: 01/30/2024

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.

15 Crankcase (pcv) problem

Failure Date: 01/20/2024

I am writing to address a critical issue involving my 2017 Chevrolet vehicle, which poses a significant safety hazard. I purchased this car from faulkner Subaru in bethlehem in 2022. The specific component failure relates to the positive crankcase ventilation (pcv) system, particularly the lack of a traditional pcv valve and the presence of a fixed orifice vacuum port in the intake manifold. This component is available for inspection upon request. The safety of myself, my passengers, and other road users was compromised due to the sudden and significant oil leakage caused by the malfunctioning pcv system. This not only endangered our safety but also posed a serious risk to others on the road. While the problem has not been reproduced or confirmed by a dealer or independent service center, it is a well-documented issue with ongoing litigation against Chevrolet. However, there are currently no active recalls addressing the problem. There were no warning lamps, messages, or other symptoms of the problem prior to the failure. The incident occurred suddenly while driving, with the strong smell of burning oil and subsequent oil leakage being the first indications of a problem. Your immediate attention to this matter and intervention on behalf of affected consumers is crucial. I urge Chevrolet to address this safety concern through a formal safety recall and to take responsibility for rectifying this manufacturing defect.

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.

18 Crankcase (pcv) problem

Failure Date: 01/16/2024

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.

Rear main engine seal failure due to blocked pcv system on 2. 4 liter dohc.

22 Crankcase (pcv) problem

Failure Date: 01/31/2023

I am a recent 2017 Equinox owner with a 2. 4l ecotec engine. I purchased the vehicle 9 months ago and have put less than 30k miles on it since owning the vehicle. On Tuesday, 1. 31. 23, while driving to a work appointment on a busy interstate my Equinox seemed to have a power failure and started making a noise. I proceeded to move toward the shoulder of the highway and before I could get to the shoulder, a warning light came on that there was low oil pressure, to stop the vehicle. Before I could safely get all the way to the shoulder, the car shut off and the engine ceased. From the time my vehicle started making noises, to it ceasing on that 4-degree weather day, was bout 6 seconds. The mechanic states the engine is ceased and that it would be about 10k for a remanufactured engine installed. No guarantees that this would not happen in the future as this is a manufacturer's defect in the size of the pcv system that is on vehicles with this motor, the 2. 4l ecotec . The mechanic states that the rear engine seal has failed. This was caused by the defective pcv valve being too small which causes excessive pressure to build up and the rear main engine seal to fail. This is a known issue for vernal motors. There are literal thousands of people in this same situation, and I could have been killed by oncoming traffic had I not been able to get to the shoulder all the way. I have documents relating to this system failure and copies of the bulletins that gm has issued their dealerships, however the file is too large to attach here. Please email me for documentation.

Gm has known about this problem for years and has done nothing to rectify it.

They knew there was an issue with this make & model, I should have been notified regarding the freezing of the pcv valve and rear engine seal blowing out. Someone is going to die because of this, they will break down in subzero temperatures and freeze to death. 12/24/2022 at 6:45 am on christmas eve.

28 Crankcase (pcv) problem

Failure Date: 12/24/2022

I arrived at my workplace. Was there for about an hour, I then went outside to grab something from my vehicle and noticed that I was leaking oil. After further inspection, I realized that I no longer had oil in my vehicle. I had it towed to my service station. After looking at it they called me and said that the pcv had gotten clogged with ice, therefore causing pressure buildup and blowing out the rear main seal. There were no warning lights whatsoever of this problem. I am just happy that I wasn't on the highway or long drive, because this would have left me stranded or worse causing an accident. From doing research online, this seems to be an issue that gm is aware of and refuses to make right. They had a recall for this exact issue for model years 2010-2014 but now are refusing to issue one for later years, even though the same engine style and pcv placement are the same. Not telling their customers about this potential serious issue is almost criminal and then not standing behind their product with either a recall or reimbursement of cost of repairing is ridiculous.
