Other Fuel System problem #1

I had a message flash that said the power to the engine was reduce. Next message said check stabilink ( or something similar). . It said drive with caution. I live 2 mins from my job I drove home and pulled in the driveway I then felt the car act like it wanted to shake. This was on 2-10-26 I contacted onstar asked them to run a diagnostic. The codes that came back p0016 p0089 p228d are very well known codes with many people with the same vehicle/engine that have had to replace the engine. The engines have known issues had I known that maybe I could have replaced a part or two or three or four to have a stable vehicle now my vehicle is currently at GMC dealer since Tuesday morning actually had it towed there Monday night. I called Wednesday evening they still wasn't sure the "issue". Thursday I wait until about 1pm spoke with john he said well we are pretty sure you need a new engine the mechanic is checking a few more things the car has no pressure. About a hr later I get a email and a call saying the timing chain skipped and something about the pistons and the valves and I need a new engine . John called me and said well. Ill tell you what we will offer you a brand new engine for the same price as a rebuild plus you get 3yrs 300 thousand warranty for 10,944. Give or take a few dollars. We'll first I paid like 15,500 for the car that I just litetally paid off like Jan 12026. I really feel like had GMC made buyers aware that the vehicle has defective parts/engines buyers could replace parts or GMC should be held accountable. I started googling the engine and found out that there is a class action lawsuit and a recall on " certain" 2017 Terrains depending on the VIN. Same issues my car is having but its saying my car has no recall.

Other Fuel System problem #2

Throttle position system all of a sudden went bad. My 2017 Terrain started shaking. I was holding up traffic. The sun couldn't go over 5mph. I've read online where this is happening alot in 2010'2017 GMC Terrains.

Other Fuel System problem #3

1st time - rear main seal blew out & engine lost all of its oil causing rocker arm to break & chains to slip-vehicle sputtered & died while driving down busy street & would not restart - my safety & safety of others driving behind me were at risk for causing a rear end accident and/or pile up crash - no warning lights or sounds alerted me - dealership told us general motors is aware this is/has been a problem with 2017 Terrain vehicles especially those driven in midwest states due to colder temperatures - the intake manifold vent hole is not large enough to let air out, so it plugs up & causes pressure to blow out rear seal, which causes oil to leak out and engine dies. When replaced with a remanufactured engine intake manifold vent hole was not drilled out causing it to happen again 2nd time - when leaving parking spot at work noticed oil puddles underneath my vehicle, I checked my oil, it showed full, I was concerned, drove to nearby last place I got my oil change. They informed me that all the oil had leaked out and showed me the bottom of my vehicle oil covered the front to the back of my vehicle. They also said that I was extremely lucky to get to shop before engine blew and stopped dead. Again my safety and safety of others behind me could have been a rear end accident and/or car pileup crash - again no warning lights or sounds alerted me - shop personal told me general motors is aware this is/has been a problem with 2017 Terrain vehicles especially those driven in midwest states due to colder temperatures - even though the repairs where done by a certified dealership the first time they replaced with a remanufactured engine but failed to drill out the intake manifold vent hole bigger so this would not happen again but it did. General motors cannot just sell vehicles it has to stand behind what they sell which in my case they have not. Due to gm lack of concern, recalls, reimbursements, lives have been and continue to be at risk.

Other Fuel System problem #4

Rear main oil seal is faulty. It caused the vehicle to leak oil to the point where it was dry. This is a known issue with these vehicles and could have caused catastrophic damage to the engine. Additionally, this can cause the vehicle to stop running and/or catch fire.
