Posting for others that might be having the same issue. If you have had any problems with oil consumption, timing chain, pistons, or PCV valve issues please call the class action office at 310-474-9111. There has already been a settlement for a variety of Chevy and GMC models but mine (a 2014 GMC Terrain) is not included. Feel free to private message me if you have any questions. The more that call the more they have a case. There has already been a settlement for several other GM vehicles so it may not be that hard to get additional vehicles covered.
Hi Ktrasher, do you work with that law firm? The rear main seal on my 2016 Equinox blew out on Dec 10, 2019. Ilive in Minnesota, and the temperature was -6 that day, so I strongly suspect the PCV valve froze. I'm going to give them a call on Monday

A 2016 Equinox ^^^
A "newer" 2.4 liter ecotec 4 cylinder engine...
Toast
Just because it was
Driven in ice cold weather
No surprise rear main seal failed ....
^^^ That is GM for you, ^^. Gm knew at least in 2013 of that failure Mode ^^



At least ,
GM does not "mur der" anyone with rear main seal failure.

As they did with their key ignition switch that "turned" off too easily...
Imagine driving along, 35 mph, your kids driving, .... they have a big keychain that is "bumped" buy the passenger...
And
It rotates to the off position,
engine turns off, because key rotated too easily, and steering wheel locks..
And you can not restart car because you are not in park..
Still going 35 mph, with a locked steering wheel....
Imagine...
So many are dead.... because of GM cheating on their PPAP for not meeting GM's minimal key rotation resistance specifications ...
And
GM got away with ^^ "mur : der"

Yup
Gm did not meet their own specifications....
And they made defective ignition switches for years...


Good luck winning against GM, They deserve a real bankruptcy... not a fake one like they got in 2009...
Good luck.. with your lawsuit...
for a rear main seal failure that costs you thousands of $$$$$
And spilled a little oil on pavement..
Brcause you drove in ice cold weather....

Just because gM made a small change, switching from port injection to GDI engine
to meet tighter fleet fuel economy specs
The same PCV system that worked fine on port injected 2.4 engine
Fails on these GDI engines....


We know that ^^^ and use vented oil caps... and drive in ice cold weather.

That’s the “Settlement” for the Oil Consumption problem caused by the bad piston rings on the 2010-2012’s (plus a handful of 2013’s built before May 2013) that The Court ramrodded through and Approved because it has too many cases on its dockets, and something like this case is easy to Close and Deny because it fits multiple legal criteria and precedent.

They paid off the 11 original Plaintiffs (in at least 3 states), $4500 each ... enough to make *them* happy, gave the lawyers $3.4 Million (8% of GM’s alleged/estimated/purported outlay of cash to “Settlement” members ... a “low” lawyer fee compared to precedent, BTW), told the Objectors to “shut up”, and turned to the rest of the Class Members (1.6 Million owners) and said, “Good luck cashing in on those (now expired) SCAs ... but you can get rental car fees if you had incurred those”.

The thing about these cases is - so much of them is shrouded in mystery. Out of the 1.6 Million owners of these 2010-2012 (plus a handful of 2013 owners) ... how many got this problem fixed (?) ... and how many got “stuck” because their vehicle “failed” one (or more) Consumption Tests (but was still burning or otherwise losing oil at an alarming rate)? Of the “repaired” engines ... how many experienced the same problem *again* (?). How much money did owners lose in vehicle valuation due to this defect (The Court conveniently dismissed *that* argument off-hand, BTW).

Everyone should’ve OPT-Ed OUT of that Class Action. Only 1700 did so, and this was one of the reasons The Court was able to ramrod it through to Closure.

The problem with these “Class Actions” is - they meet the requirement for a class-action in terms of *size*, but they get SO big that they become too disorganized to effectively attack the Defendant. So then The Court steps in and just starts looking for every reason to wrap it up and close it out.

And then ... you ... the “little guy” gets next to nothing while the lawyers and a few hand-picked Plaintiffs laugh all the way to the Bank.

These two parties basically use YOU to get what THEY want from the Defendant (i.e.: 11 people isn’t enough for a Class Action Suit). What we (the “little guys”) should try is ... organize 1.6 Million individual lawsuits (or some otherwise very large number), filed simultaneously (in Small Claims Court) across the country, and make sure we’re all on the same page, with the same Complaint, and same Demands. Then we’ll see how The Court handles *that* surge!

But ... as far as this particular Case (Excessive Oil Consumption) ... it ended just like they all do ... “DONE and ORDERED”! (Or whatever that goofy language is the judge stamps on the paper to make it all disappear...)

I own a 2012 terrain with 2.4l eco engine covered under the TSB oh wait the VIN number is not listed sorry you owe $972.00 for repairs. This despite the dealer stating the cause of the seal going is a freezing or blockage of the PVC system on the vehicle. The blockage occurs in a drain line under the cowling where a tube comes out the cowling and is lower than the drainage line. In order to drain the water and fluids have to go up hill. So the car cools the water that condenses flows into the line but can't drain and causes a blockage and poof out goes the main seal because the engine is over pressurized. Very poor design unless the line in question is lower than cowling. My car exhibited every sign, noise, warning light, stated in the bulletin. But because my car was built in Plant A and only cars built in Plant B are covered by the VIN will only be fixed. The dealer stated the cause was this PVC SYSTEM BLOCKAGE, the TSB describes everything the car exhibits when it ran, the dealer on my receipt states all repairs done under warranty coverage including all parts and labor. The TSB states customer not responsible for cost repairs. Yet I have to pay $972 for repairs to something GMC has acknowledged is a problem to my vehicle. I complained to Chevy via customer service. Told me that my case would be considered in front of a committee that reviews cases to see if Plant A cars should be considered for inclusion of TSB that Plant B cars are in. Gave me a number waited no response, called again gave the run around and gave me another number with the same song and dance. Got a call from GMC want to talk. WE shall see. I'm a life long Chevy customer no satisfaction will look else where and encourage others to do so. Your turn GMC.
I have 2013 Terrain.I I took my truck in after receiving notice from GMC regarding oil consumption I knew i had been loosing oil but couldn't understand why. Turns out My rear seal also went out ($2600+ later) . I was told the cause was the hot and cold temperatures. GM repaired the piston ring seal at no cost to me but i had to pay for my rental. During the rear seal repair they discovered the exhaust manifold needed repair as well I was told it would be another ($500+) That comes to a grand total of over $3000. So I elected to wait on exhaust manifold. When i took my truck back for oil consumption test I was told to repair the exhaust manifold would now only be $250. So i had that repaired as well. When picked my truck up after repairs were complete as i pulled off the lot a bolt fell out. Mind you they had to keep my truck an extra day because they lost a bolt. So they took my truck my back in to make sure everything was working properly. That tool about 45 min. As soon as i thought i was all set I checked the oil gauge it read 67% remaining. I was told it mechanic forgot to reset it and to put the next time oil change sticker in my window. I just have just 2 questions how can i get in on lawsuit and could the oil consumption malfunction have anything to do with rear seal or exhaust manifold malfunctioning?

You already got a free set of replacement piston and rings?
Are you burning oil again? Ask the dealer to do another oil consumption test, you might get another free set of piston and rings...
Oil consumption is not related to rear main seal failure and visa versa..

Did the dealer scam you with rear main seal replacement? When rear main seal failed, it failed catastrophically.....you literally loose quarts of oil in a few minutes....

Oil consumption is caused by the process caused LSPI, where carbon falls of intake valves while deriving at low RPM under load, like driving at under 2000 rpm and up a small incline like an overpass on a highway...
The carbon falls into combustion chamber and gets lodged on the pistons upper compression ring, inbetween piston and cylinder wall
Then this piece of carbon becomes oil and gasoline soaked and ignites the combustion charge... instead of only spark plug igniting the combustion charge.
Igniting the combustion charge in the location of the pistons compression ring results in erosion of the steel of the piston in the area of the piston ring grooves, into which the compression rings snap onto and weakens and wears the piston ring itself.
Thus creating a leak path, from crankcase into cylinder for engine oil.

The oil consumption is worsened since high crankcase pressure from piston blowby, pushes oil into cylinders from crankcase, at the same time as piston is sucking air into cylinder during downstroke. High crankcase pressure is not helped by crappy GM PCV design.

LSPI explanation ....==>
https://www.enginebuildermag.com/20...e-direct-injection-issues-facts-fictions-gdi/


Rear main seal failure is unrelated to oil consumption
Rear main seal failure occurs because. You drove your terrain when it was freezing cold outside,. Your rear main seal will fail again if you drive your terrain when it is freezing cold outside.... hence all the discussions on vented oil caps....

My 2 cents ^^^^

I have a 2010 NOX that just had this exact problem, but GM says the VIN does not apply :angryfire:. Regardless, I didn't see it on this forum, so here is a copy/paste of the TSB:

http://m.gm.oemdtc.com/Recall/SB-10057977-8108.pdf

Bulletin No.: 14882
Date: March 2015

SPECIAL COVERAGE
SUBJECT: Special Coverage Adjustment – Plugged PCV Orifice in Intake Manifold
MODELS: 2010-2013 Buick LaCrosse
2011-2013 Buick Regal
2012-2013 Buick Verano
2011-2013 Chevrolet Captiva
2010-2014 Chevrolet Equinox
2013 Chevrolet Malibu
2012-2013 Chevrolet Orlando
2010-2013 GMC Terrain
Equipped with 2.4L Ecotec Engine (LAF, LEA or LUK)

CONDITION
Certain 2010-2013 Buick LaCrosse; 2011-2013 Buick Regal; 2012-2013 Buick Verano; 2011-
2013 Chevrolet Captiva; 2010-2014 Chevrolet Equinox; 2013 Chevrolet Mailbu; 2012-2013
Chevrolet Orlando; 2010-2013 GMC Terrain vehicles equipped with a 2.4L engine (LAF, LEA or
LUK) that have experienced high oil consumption may also experience a frozen and/or plugged
PCV (positive crankcase ventilation) system during cold weather operation. This condition may
increase crankcase pressure leading to a rear crankshaft seal oil leak. If the oil leak is ignored or
not noticed, an engine clatter noise may be noticeable and/or the engine pressure warning light
may illuminate. If this condition is not corrected, continued driving with engine noise and/or the
engine oil pressure light illuminated may damage the engine.

SPECIAL COVERAGE ADJUSTMENT
This special coverage covers the condition described above for a period of 10 years or 120,000
miles (193,000 km), whichever occurs first, from the date the vehicle was originally placed in service,
regardless of ownership.
Dealers are to perform a crankcase pressure check, and if required, remove the intake manifold
and clear the PCV orifice. The repairs will be made at no charge to the customer.
For vehicles covered by Vehicle Service Contracts, all eligible claims with repair orders on or after
March 4, 2015, are covered by this special coverage and must be submitted using the labor
operation codes provided with this bulletin. Claims with repair orders prior to March 4, 2015, must
be submitted to the Service Contract provider.

VEHICLES INVOLVED
All involved vehicles are identified by Vehicle Identification Number on the Applicable Warranties
section in GM Global Warranty Management system. Dealership service personnel should
always check this site to confirm vehicle involvement prior to beginning any required inspections
and/or repairs. It is important to routinely use this tool to verify eligibility because not all similar
vehicles may be involved regardless of description or option content.

PART INFORMATION
Parts required to complete this special coverage are to be obtained from General Motors Customer
Care and Aftersales (GMCCA).
Note: Use the vehicle identification number (VIN), SI and the GM Electronic Parts Catalog to
determine which parts to order. The Crankshaft Rear Oil Seal Replacement procedure in SI states
what parts are required to complete the repair. For example, gaskets, one-time use fasteners, and
fluids.

Part Number Description Quantity/Vehicle
12591866 Crankshaft Rear Oil Seal 1

Repair procedure omitted for space. Click on the link above if you would like to see more
Did you get anywhere with GM? This just happened to my daughters 2012 captiva and we were told that the vin doesn't show coverage.

Probably screwed

My husband and I have a 2012 Equinox 2.4L and we looked up the bulletin after our Equinox caught fire on the highway because of this issue. We have the car at our local GMC dealer (closer than chevy). We have only owned this car since December 2015 and the bulletin got sent out in March 2015 so we didn't get the letter. However a couple months ago we got the oil consumption recall letter in the mail. We thought we had that issue because it burned oil really fast one week but once we got it up to our local chevy dealer and they wrongly (we just found out from GMC) did the oil consumption test. But it didn't burn any oil before 2000 miles and they said if it didn't that it didn't need to come back so we never went back. So I talked to a lady at GMC and she said that our VIN didn't bring up any recalls and doesn't qualify for the service bulletin because our specific engine wasn't built at a specific place. But on the bulletin it says nothing about the engine having to be built at a certain place or during a certain time frame. So we're waiting to hear back from our GMC dealership and I also have a claim in the Chevrolet (not a dealership the actual company) and I should hear back from them in a couple days and if GM as a whole doesn't fix my vehicle my husband and I will be talking to an attorney.

We also only have 107,000 miles on out equinox so we're well under the 120,000 marker.
Any updates on this? 10 degrees outside and my daughters 2012 captiva just lost the rear main at 106K. Dealer saying vin not covered.

This Service Bulletin seems to say you're covered (10 years OR 120,000 miles, whichever comes first), but here's the gotcha: When was your 2012 Captiva "placed into service"? IIRC, weren't these Captivas all sold used .... weren't they former rental vehicles (or something like that)? Typically, a GM product built for model year 2012 would start selling in late 2011, so if that holds true here, then you'd be covered ... but maybe the Captiva was one of those models that had an oddball production run ... and so your 2012 may have been "placed into service" in January of 2011, putting it just past the 10-year coverage window??

If you didn't buy this Captiva brand new, then I'd try calling GM to ask when your VIN# was "placed into service". Good Luck!

My 2014 Chevrolet Equinox's PCV valve clogged and caused the rear main seal to blow out. Now I am being told that I need a new engine?

Yep, makes sense. Happened to many people. You may be best to find an independent garage that you trust, and get a quote on putting in a junk yard engine. If you go to the dealer, the cost will exceed the value of your car.

How many miles are on the vehicle.

.
102,282 miles....2 quotes from independent shops - one said $6000 and the other $5500. Dealer said $8000-9000.

my 2014 equinox pcv froze, blew out rear main seal. 95k miles.. 4450 torepair the seal or 7600 to replace the motor because there is no way to know if there was any engine damage without taking it all a part. this is nuts! The dealership said " I know you didn't do anything to cause this, its a known issue" but yet wont fix it. even tho there's a resent 42m settlement for 2010-2013 and the 2014 were said to have a new pcv system that won't have this issue. I call BS BECAUSE MY 2014 HAS the same issue that all the others had. I should NOT be responsible for something THEY KNOW IS AN ISSUE WITH THEIR PRODUCT!! There were no warning lights on nothing until it popped up on the screen power reduction and 30 sec later shut down when we were going 65 on a busy interstate.. THANK GOODNESS we were able to coast out of harms way!

can I get an update on the outcome of this please?

I am currently dealing with GM due to the same issues My 2016 Equinox engine blew due to faulty pcv valve. I have only had it 2 years and I owe $15,000 on it. My extended warranty won’t cover it because it excludes weather related problems. The valve freezes when temperatures get below 18, causing it build pressure until the rear main seal blows. The oil blows out and the engine blows. I live and bought the car in the Midwest. I am currently fighting the dealership. They have known of this issue prior to 2015. My car is a 2016. The service manager told me that there are 9 GM models with this problem. She also said there is no warning to prevent it from happening. Every solution GM and the dealer come up with results in me paying $5,000. I keep telling them, “I. Maintained the car as I was suppose to. GM is knowingly using faulty parts. I am not liable. I did nothing wrong. I’m not paying anything.” I currently owe $15,000.

The 2014 Equinox (with 2.4l engine) was included in that 14882 Service Bulletin! Were you notified that your vehicle was affected? If not, had you been to the dealership for servicing when you should've been notified in person?

Also - your vehicle was within the constraints of the Service Bulletin (10 years or 120,000 miles), so it should've been serviced to (help) prevent the problem from occurring.

But even if all that was missed, you should still be eligible to have the Rear Main Seal replaced free of charge! And then hope there's no real damage to the engine, which may have been the case since it sounds like it shut down quickly.

======
You people with the 2015, 2016, and 2017 2.4L Equinoxes that are blowing out the Rear Main Seal ... if there's no Service Bulletin for you, you're gonna have to start your own legal action, I guess. If you can prove the same problem exists in these later model Equinoxes, I would think the case would be a slam-dunk victory for you (to get enough money to at least replace the engine).

Just had my engine replaced in my 2017 GMC Terrain due to frozen PCV valve. When I got the car towed to the dealership I told them I know they have problems. They called me back the same day and said GM will split the cost of $7,200 with me and my share would be $3,600. I emailed GM directly and only had to pay $1,000! Got my car back last Friday and now it purrs like a kitten. Here is the contact to get **** done.

Just curious, would you mind sharing how many miles you had on your 17 Terrain when you had this happen, were you past the 50,000 mile power train warranty?

The moral of the story and info is here in several threads. . . . install the FC219 venting oil cap may help prevent blowing out oil seals in sub freezing weather.
Better yet . . . reroute and/or install a larger PCV hose from the valve cover to the air intake plenum with no "dip" in that line so moisture can not accumulate and freeze.
Those two DIY things would prevent the majority of 2.4L frozen PCV path issues and main seal blow out , , , ,and the $$$$$ cost of replacing an engine for such a simple fix.
