We need to stand united and fight GM

A week ago today, my 2013 GMC Terrain rear main seal failed due to the PCV system being plugged/frozen. To make a LONG story short, we've been getting the run around from GM. All they can say is get it to a dealer, and have them look at it, but since your out of warranty we will not compensate for the repair cost. Yesterday my wife and I went to a dealer, and were told that we made the right decision to bring it to our mechanic and not them.

For the first three years of ownership, maintenance was done by a dealer. They never mentioned anything about the oil consumption these engines are known for. The first time we bring it to our mechanic for an oil change he tore into us for letting the oil go so low. We had no idea that this engine burned oil until he told us about it. So because of this, we lost all trust in our dealer, which is why we brought it to our mechanic after the rear main seal failed because the dealer wouldn't have said anything about service bulletin 14882. While our mechanic told my wife to call GM, and gave her the bulletin number. The customer service representative told my wife that he couldn't find the bulletin. When I called the next day, and dealt with the same person. After telling him that I found it on Google, he miraculously found it.

I've been tweeting the service bulletin, and an ACDelco Canada Techconnect article that I found. What I need from you members is support. Either by sharing the links in your own tweet, or retweeting my tweets (@chrispyberry) so GM realizes that I'm not the only one affected by this manufacturers defect, that GM knows about, but only covers certain VINs for up to 120,000 miles. The PCV system is poorly designed. GMs' customers didn't design it, so why should we be held responsible? Regardless of how many miles, or how old the vehicle is, GM needs to stand up and do right by it's customers.

United we stand, divided we fall

Owners manual specifically says----
Engine oil fluid levels should be checked at every fuel fill.





This comes to checking levels around every 300-500 miles based on your MPG's./roughly every week for many of todays commuters.

Solrain,

I can understand your frustration. It is absolutely possible that the design is flawed. However, this engine is used in MILLIONS of vehicles. The rear main seal leak from a plugged PCV actually seems to be a rare occurrence.

I had a 2012 4 cylinder and never had an issue for over 6 years and 120000 miles. I live in southern Ontario, so it gets cold. I am also VERY particular when it comes to car maintenance. I know exactly what my vehicle is supposed to sound like and when maintenance needs to be done (never used oil life monitor). You could hear the ticking of the valves at start up when my 2012 was slightly low on oil. Between my 2010 Malibu, 2011 Regal and 2012 Terrain, I have put well over 300,000 miles on the supposedly crappy 2.4L Engine with no major headaches. Sure as they got older they burned a little oil. Nothing to make me want to bail on GM.

All my experience with GM is not great. My 2010 Malibu had electrical issues that caused the door locks to fire open on their own. My 2007 Buick Rendezvous transmission died at 6 years old and 115k miles. I took it as a lesson learned and moved on.

All purchases have inherent risk. Your Equinox is now 6 years old and from what I understand you had no other major issues. Judging by the fact that the vehicle was driven with very low oil (on the highway after it stalled) and when your mechanic found it very low on oil, it seems like you may of dodged a bullet. The reality is the engine could have easily been lost if you drove it with no oil.

Take it as a lesson learned and check vital fluids in your vehicles on an on-going basis (coolant and oil at a minimum every month). If that is not something you want to do, then accept the risk that something may fail.

Not sure how feasible it would be but - since oil is more important to an engine than gasoline, ideally every engine would be equipped with an automated Oil Level Monitoring System - similar to a gas gauge.

That way you could see the level dropping over time.

Not a lot of love for the OP here but I feel your pain. My 2011 Terrain SLE burned oil like crazy. I literally had to add two quarts of oil on two separate occasions between actual oil changes (once I was over 70,000 miles) and no I didn't have any leaks. I had a lot of personal life stuff going so I never pursued anything with GM just kept adding oil when needed. GM doesn't go out of their way to alert owners of issues in my opinion. Despite that, I purchased a 2019 SLT in October. I took my 2011 in for service and was given a recommended service workup that was in excess of $10,000. I traded it the next day for my 2019. Maybe I should feel bad since I got a nice chunk of change for it but my feeling is they got back the flawed vehicle they sold me.

I'm surprised all cars don't have oil level sensors.
Our 2003 bikes had oil level sensors and so does our 2016 bikes.
I think this started around 2005. You get a message on the dash when the oil is down to the minimum mark.
Since 1988 our bikes have not had a dipstick. On the wet sump engines the bikes had a clear window in the sump and the dry sump engine had a clear tube on the side of the oil tank.
In the first picture you can see the site tube next to the gray frame. Oil level marks are on the tank.

I had an Audi A4 & Allroad that had both oil level and temp sensor.

Please tell us more about the recommended service workup that was in excess of $10,000.
