I own a 2017 GMC Terrain SLT with a 2.4L engine. Back in February 2023, with the temperature down to 1 degree Fahrenheit here in Buffalo, New York with a wind chill temperature of @ -12 degrees. That morning, we heard a pop and the engine sputtered. When I pulled it into the garage, I noticed a large oil stain on the driveway where the vehicle had been parked, which is odd since we’ve not had any drips from this engine prior to this incident. I then checked the oil level and didn’t see any registering on the dipstick. It took 2 quarts to bring it back up to normal levels. I started the engine again and looking under the vehicle, I could see oil dripping heavily where the back of the engine meets the transmission. We kept the vehicle parked in the garage until I could get it in for service the next day.

The dealership called and advised that the PCV system clogged/froze and the main real seal failed. The total repair bill ended up being $3,200 but could have been higher if the engine had lost all of its oil. The Service Advisor told me that they actually had another vehicle in for service with the same exact problem as mine. I saw that there was a GM Technical Service Bulletin (TSB 14882) opened back in March 2015 but this TSB only covered 2010-2013 GMC Terrains with a 2.4L. In this TSB, GM did recommend for full customer reimbursement but only up to March 2016. I feel that my 2017 GMC Terrain (2.4L) had the same engine problem as referenced under TSB 14882 and that GM should reimburse me as well as other customers in this same situation but no luck so far.

Has anyone with a 2017 2.4L have a similar problem but get reimbursement from GM? Thanks much

 

Friend of mine had same problem and expense. Dealer told him orifice in PCV valve was not large enough causing ice to block it in extreme cold. Some suggestions are to drill out to larger dia.

 

Thanks for your response
