My daughters' 2011 Terrain with the 2.4L Ecotec engine suffered high oil consumption followed by a totally blocked PCV tube which caused a blown real seal. Exactly as described in Technical Service Bulletin #14882 which advise of an extended coverage for this failure. For 8 models in the 2010-2013 model years including Terrains and other models using that engine and series LAF, LEA & LUK.

GM Dealers are missing this TSB because the VIN tracking system doesnt pull this TSB 14882 up. GM hasn't been able to identify for me why our Terrain with this exact problem and exact engine type and exact engine series isn't listed and didn't receive the GM Notice. Less than 2 weeks after having it in to a GM dealer where the excessive oil consumption was noted the rear seal blew on a cold day. Now the dealer wants to do either a $3600 repair or $5000 engine replacement but GM refuses to honor the TSB extended coverage. :mad:

Anyone else hit with a rear engine seal failure on their Terrain?

WOW!..I would get together all the documentation you can find on the issue and write or call GM directly... and then if you get a run around, threaten that you will be putting it in the hands of an attorney.

Me Too!
I have a 2015 GMC Terrain with the 2.4L motor, it has 78k miles. I have maintained this vehicle throughout. Yesterday, in single degree weather the rear main seal blew. My mechanic found Bulletin 14882 and referred me to the GMC dealership I had bought it from. First, they denied a problem, I told them about the bulletin. When Steve came back to the phone, he said he found it and said there was no coverage for this problem.

I explained that there are many cases found easily on the internet and even a Lemon Lawsuit. He just deflected. He gave me the GM Assist 800 462 8782, the lady was pleasant enough, when I asked if GM was going to stand behind their defect, she deferred me to her manager, saying that I would get a call back in 1 – 2 days. Meanwhile the car sits leaking in the driveway.

Any ideas on how we can join together to make some noise and get some attention?

So I had the same issue on my 2017 I posted above also was really pissed off at the time when I posted it.
Gm warranty will tell you till they are blue in the face that it is "VIN" specific. That is bull sh**. When I eventually contacted the GM dealer I got the car from he pulled up the bulletin and said I see nothing saying this is specific to VIN#, if it is the problem then will fix it.

Turns out that was the problem and they took care of the warranty service at the dealership. I asked him if that is the case then why did I get told this by the warranty service he said they don't care and not to talk bad about GM but they have horrible warrenty service.

I would say keep contacting the dealer. Don't mention anything about the Vin. If they do the. You read the bulletin because if it was verified to be specific to Vin then it would say so in the bulletin not just word of mouth from them.

Anyone that thinks they might have this issue, if the car is shuddering a little or feeling rough while driving either you or have a professional check the PCV valve it might be clogged. Pcv valve is easy to replace and cheap compared to a blown seal from a clogged PCV valve.

Is there a different TSB? The one mentioned is only for Terrains up to model year 2013.

The one I found was from 2015-2017 i can't find it now I had the link in another forum. The tab 14882 is for 2010-2013


The one I found might have been then same but it said all 2.4L engines that have this issue.
The manager I had spoken to looked it up and told me yup that what he reads also.
Now when I look for it all I can find are ones showing years that my 2017 wouldnt be apart of. It was only few months ago.

But for everyone's knowledge this problem is still happening with the terrain in 2017+

Hi, did your dealer handle this issue under warranty? I have a 2017 Terrain and it is at the dealer now - purchased 02/04/17 - they are telling me that is when my warranty expired! I am going to lose my mind and looking for assistance on how to resolve if they don't cover it.
