I noticed my oil l was leaking severely. I had to add oil between changes even. Ended up having both seals replaced less the 2 months ago. It is still leaking. I have to have my oil changed every 2 weeks and add 2-5 quarts between changes. Just put my 2015 Terrain back in the shop at the dealership. They informed me that there is known issues with the piston rings in previous models. Why has there not been a recall issued for this known problem? I just spent almost $3000 2 months ago and am probably looking at that much again to have the issue fixed. It's my daily driver vehicle. I live out in the county so it's a combination or highway and city driving. I do not drive crazy or hard. I routinely take care of all maintenance on the vehicle. There is no reason I should be having this issue.
Smelt something burning while driving. Car started bucking and jerking. I pulled into a parking lot and noticed a puddle of oil leaking out underneath my car. No check engine light or any notification that anything was wrong. Had it towed to dealership and they told me pvc froze up and blew out rear main seal. This is the 2nd time this has happened to us this year. We own another GMC (2013 equinox) and the exact same thing happened 2 weeks earlier with it. Frustrating that GMC is aware of this defect with their engines and not willing to issue a recall to correct it. We had to pay $2500 to fix the equinox. Luckily the Terrain is still under factory warranty but with both cars we were out of a vehicle for several days. Will it happen again???.
I have a 2015 terrian sle. Around 57,000 miles my terrian started burning 2+ 2+quarts of oil in between oil changes with no apparent reason, I have always kept the oil changed before it got below 7%, after noticing the oil levels dropping fast I checked it everyday. The engine light came on with my last oil change, 2 weeks ago, showing 2 bad cam sensors p0010 and p0011. I went to my mechanic only to find out that the 2. 4 motors have been littered with oil leaks, timing chain problems, cam sensor issue and stalling. I paid good money for this car and I am not pleased with the continuing motor problems from GMC. If the same problem that occurred on early models is still happening, why is there not recall? I am frustrated as I have only one vehicle and the out of pocket cost is ridiculous, especially when I'm being told it's cheaper to buy a new crate motor than fix what is wrong. I have always been a fan of GMC until this. It's no wonder why everyone has switched to foreign vehicles, the ones made in the us are so cheaply made and priced 3 times there value.
