2016 Gmc Terrain Complaints

I check my oil every time I get gas as to ensure that i don't go below the threshold for the oil, as I know these engines have an oil consumption issue. My terrain started having a loud grinding sound after losing power on the highway and I was able to pull off before the car died completely over 60 miles from home. I have since changed the upstream, and downstream O2 sensors (they needed it), VVT solenoids, and now going to be required to change my catalytic converter because the excessive oil consumption has clogged it almost completely. Why will GM not issue a recall for this engine and get it fixed, when they have knowledge that there is an issue. A recall was issued for previous years (on the same model) having the same issue, but yet we are left to "figure it out" at our own expense? Come on GM and the NHTSA, get it together and issue a recall already, you have all the complaints, and history you need to start one.

Carr paused, and then stopped in the middle of the highway, without any warning lights or identifiers. Other vehicles had to come to abrupt stops or even veer to avoid hitting me the manufacturer is aware, and has had a large lawsuit settlement due to a faulty rear seal causes massive internal oil consumption without any warning to the operator of of the vehicle. My research has shown that it is a catastrophic common issue with this vehicles model and year a certified GMC dealership has identified this as the reason for the sudden shut down without warning, not one warning light illuminated to indicate low or any other issue. The car has had regular oil changes and maintenance. This well-known defect should normally be caused for alarm and the safety of drivers would also for a mass recall.

excessive oil consumption....caused engine to fail....yes, car is available for inspection ...caused the car to lag and initially break down without any warning lights ...confirmed form dealer new engine needed...law suits in other states have proven that this seal problem has been known to GMC for years and they haven't repaired these faulty parts...again, no warning lights came on...please assist

I bought the vehicle in November of 2025. No warning lights or problems running. Check the engine oil upon purchase and have the dealership sticker showing oil change was recently done and oil showed that it was full. Approximately 3 weeks after purchasing, the car starting idling rough and stalled a few times during my commute to work. The check engine light came on and it showed that the vvt was a possible solution for the code P0014 this was on December 12th 2025. I replaced the suspected part with no change in vehicle condition. I checked the oil and found that it was empty/no oil on dipstick. I had to add 5 quarts of oil and then it showed it was in the safe zone on the dip stick. Today (January 15th 2026) I checked the oil again and it showed no oil on the dipstick. I had to add 2 quarts for it to be at the bottom of the safe zone on the dipstick.

the car is having stability control issues
