2017 Gmc Terrain Complaints

I am filing this complaint to report a catastrophic engine failure involving my 2017 GMC Terrain equipped with the 2.4L Ecotec engine, which I believe is the result of a known manufacturing defect related to excessive oil consumption and premature internal engine wear. At approximately 88,000 miles, my vehicle experienced severe engine failure, including excessive oil consumption, timing chain failure, and complete engine failure, which has been confirmed in writing by a licensed repair facility. The shop determined that the engine failure was caused by oil starvation resulting from excessive oil consumption, leading to internal engine damage and timing chain failure. This failure occurred without warning and rendered the vehicle unsafe to operate. Sudden engine failure creates a serious safety risk, including loss of power while driving, inability to accelerate, and increased risk of collision. This engine failure matches a well-documented defect pattern involving General Motors’ 2...

[XXX], our 2017 Terrain Denali displayed code: “Low Oil/Shut Engine Off” so had it towed to Laura Buick/GMC Colllinsville, IL. Laura confirmed the issue was blown rear seal due to design of intake cover and PCV. They checked with aftermarket warranty for VIN [XXX] , warranty contract number [XXX] who said it was not a covered issue. We called Warranty folks also and were told it was an “external issue” and not covered. Appealed to GM Customer Service who said VIN was not covered. The vehicle has approximately 83,000 miles and we referenced PIP5093B and Special Coverage Program number SB-10057977, and Special Coverage Adjustment 16118 Excessive Engine Oil Consumption. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This car burns 1 quart of 5w-30 synthetic blend oil every 200 miles! The pcv valve has been cleaned numerous times and this does not affect the burning oil issue and yes this can be inspected upon request. Safety put at risk you ask, this is a ticking timebomb ready to ruin the engine due to burning oil, leaves me stranded in my rural town for fear of mechanical breakdown, need to carry two 5 quart containers of oil, and dipstick needs to be checked every 100 miles. I have scheduled appt with GMC dealer in Chadron NE for mid January 2026. There are no warning lamps or messages that appear and this problem has been going on since August 2025, bought the car February 2025 from Chevy dealer in above mentioned town. KBB has a trade in value for this car at 1500 and private sale at 1900 for a 2017 Terrain SLT! Unbelievable!!!!!!

For a year we have had to check to the oil weekly and add oil due to the vehicle burning oil so quickly. The past month we have had to check it daily and add oil. We do regular routine oil changes and have had to get them before the next one is due. Recently when driving the “oil pressure low stop engine” light has been coming on almost daily. The oil change company has reported to us that it is due to the 2.4 Eco tech motor. You can smell the oil burning through the vents inside the car.

The power steering assembly failed and caught on fire. This then caused the engine to malfunction and no longer work. This happened while driving on the interstate at a speed of approximately 80mph. No prior check engine lights were visible
