What owners say about the power train

Verbatim from NHTSA complaints, newest first
“I bought this vehicle and NHTSA made GM release an extended warranty on this vehicle for excessive loss of engine oil. In 2019 I had to take this vehicle and pay several thousand dollars for the pistons to be replaced in my engine because I was 1 year past the extended warranty. Now 3 years after spending thousands of dollars through a certified GM store I am having the same problem excessive loss of engine oil. I have zero leaks and I have to put oil in my engine every other day. If I do not by the end of the week I will have an empty engine.”

“Ok so my 2011 GMC terrain just went over 150,000 miles I bought this vehicle used from a dealership not knowing that there was a big lawsuit or that GMC continuted making this make and model knowing that it had a oil usage problem. So mmm mmm with that being said let's start with my vehicle uses oil, my vehicle idles high low and always rough at times, my service stabilitrak flashes, my motor sounds like a HEMI kock knock knock instead of a 2.4, doesn't matter where I'm at or where I'm going I let off of the gas and my car dies.... Let me clarify on that last one me and my 9 year old daughter we're headed home today let off the gas to go around a curve and a hill and you guesswd it my 2011 GMC TERRAIN died I lost all control and all power had no power steering and no brakes... I just thank Jesus I wasn't speeding and that there was no oncoming traffic cuz I don't think me nor my 9 year old would have made it out ok. So thanks to whatever faulty motor engine or power train GMC has with this make and model putting people's safety and lives in danger due to these issues and only choosing certain VINS eligible instead of all VINS from 2011 GMC TERRAINS in my…”

“The 2.4l ecotec motor has had so many complaints not only for gmc terrain but also the Chevy equinox. The motor just stops and lose everything while driving! I was in traffic and it stop almost causing an accountant God I wasn't hurt! Now I have this car with a blown motor because it's a no tolerance motor. We spend so much money on these vehicles and spend so much to keep them safe for driving on the road and yet when it comes to the company cutting corners to save money they don't get faulted for putting faulty equipment in these vehicles. I have a 2011 terrain and I bought it in 2019 for 9000 and drove it a month before the motor blew it has less then 100000 miles on it and for me to get a new motor it's another 5000. I just don't understand why if the equipment is faulty and so many complaints have been posted about the same issue why it's not being recalled or why we can't get the company to give us new motors or a new car! We are expected to pay insurance registration inspections test every year and pay for the normal wear on the vehicles to make sure they are safe but they can't recall faulty parts! I foster children and can't afford to make expensive…”
