The frequency of adding oil to this vehicle is absurd!!!!!! bought the car brand new in 2014 from the dealership and it seems as soon as the warranty was up (because its not covered under the standard warranty) I had to replace the camshaft position sensors. Did both at the same time in my garage... not cheap but the engine stopped stalling out mid drive... Oil filter was just covered in crap and sludge but no metal was detected in the used oil or the filter.. only ran full synthetic through the engine.

Then about five years after the same codes and issue with the stalling while driving happened again. Same code and the same result.. Took it into the dealership to have it resolved and the car was almost two quarts low maybe three weeks after it had a fresh oil change... (the dealership was the one that informed me about the oil consumption issue with this motor) but its inside of there allowance for burning oil. Bullshit!!!!!! The next time was not worth the 1800 dollar price tag to have them replace them again so did it myself again to just be able to still have a vehicle... now in 2024 The engine still hasn't been replaced and nothing has been done with this issue and we still have the car.. 106500 miles on it now and the same camshaft timing sensor is causing the check engine light again. My neighborhood mechanic says just get rid of the P.O.S. It will never stop happening until the engine is replaced or they come up with a solution... fed Up with the rough ass engine sound and the bullshit dealership excuses.. Need to start a class action suit against GM for the state of Ohio...

We bought a 2014 GMC Terrain for my 17yr old daughter. We researched, did our due diligence and thought we knew the potential issues.

NO ONE along the way mentioned the “common problem” these vehicles have in cold temps with the PCV system freezing and essentially blowing the engine on the side of the highway in freezing temperatures!!!

See https://www.tsbsearch.com/GMC/19-NA-021 for this TSB.

This is RIDICULOUS. I was quoted $5k for a new engine and $1500 for the labor!!!!!

GMC knows of this issue and now I’m dealing with a repair that’s more than half the purchase price for a car we bought less than 3 months ago.

I find it appalling that a dealer isn’t required to disclose known issues like this - this is preventable and there is NO warning or indicator light prior to the engine blowing due to the oil leaking out.

So there was a recent recall on the 2010 to 2013 GMC Terrains for using too much oil and GM replaced the motors or paid back the ones who paid before the settlement. Well, when I saw this, I went to check the oil and there was none on the dipstick. Now I still had a couple more thousand miles to go before an oil change and the car was showing around 60% oil life. Please keep an eye on your oil levels as I check it often and have to add oil every so often. If anyone else is having these issues, please make a complaint, as my mom's Terrain (same year and model engine) had blown due to no oil, and had 90,000 miles.

I'm looking for help. Our 2014 Terrain has encountered total engine failure, and per our local mechanic the engine needs replaced. The oil pan was completely empty, bone dry, yet the oil remaining life shows 31% remaining. While I haven't seen 2014 listed, I'm pretty sure this is the exact same engine that has been listed in other class action lawsuits for other model years of the same 2.4L Ecotech engine.

I reside in Indiana, and am looking for any help or guidance in seeking compensation to cover the engine replacement. My local mechanic told me there's no compression and the engine is shot. $4000 for a used replacement with 100K miles on it, or just under $8000 for a new engine. I need help, and not sure where to turn. Thank you!

My 2014 terrain with the 2.4l engine has the same problems as the class action suits of previous years, and same year alike. The engine burns oil and doesn't notify of low oil. I had to replace a timing chain that went bad due to this oil burning, and it still continues to do it. The engine makes noises it shouldn't, and I need to put at least a quart of oil every time I fill my gas tank!!!

You would think they would have to do something about this as they are well aware of the problem. Whats even worse is I just got this vehicle used a month before the timing chain incident. I bought it from a gm dealership, so they obviously knew of these problems and mentioned nothing.

I have maintained the vehicle with the recommended oil type, had the solinoids and timing all replaced at 72K miles (< 30 days out of warranty - blame the dealership who changes the oil for not noticing). It was just shy of 5K miles from the last oil change and the car started like it was a diesle engine and then it started dying at slow speeds.

I took it to an independent mechanic who found brown milky substance on the spark plugs and the oil was completely gone from the engine. They replaced the solinoids again, flushed the engine and put in new oil and filter. Currently at 300 miles, I have seen no oil missing but I don't want to have to check the oil every 100 miles to ensure that it isn't burning it. This is obviously a problem for many and, like them, I'm a bit miffed that I am stuck with a vehicle that I can't count on when it should have lasted me at least 250K miles before concern. My family has owned GMC products for a long time and needless to say besides me, my father and brothers are not thrilled.
