Carrier/rack Problems of GMC Terrain

My vehicle eats up oil. I just recently found out about the excessive oil consumption investigation. My check engine light has been coming on. Sometimes when I fill it with gas it goes off. A week ago it came on and then as I was driving down a busy street my traction control light came on, then a message on the display saying service stabilitrack and engine power is reduced. I couldn't go over 35mph. I took it to oreily the following morning and the code p0175 showed �fuel system too rich�. I found a recall of an O2 sensor. I couldn't get into a gm shop for another week. Today they fixed the recall but told me the special coverage adjustment for the oil consumption was expired in 7/2020 for my vehicle. I chatted with gm online and they didn't answer all my questions. Even though I found the info on this here website about the investigation and the time limit and mileage on when I could get this problem fixed, gm would not explain in detail to clarify this info. It said 7 years and 6mos or 120k miles from when the vehicle was placed in service. They said third party sites like these aren't reliable. The shop mentioned I should just keep oil in it and that getting the pistons fixed would be $5k. My extended warranty does not cover and I was never notified about the investigation otherwise I would've never gotten the vehicle or at least got it fixed in said time limit.

On 08/05/2020 I was sold this vehicle with a cracked manifold. Upon replacement of the manifold it was discovered that two manifold bolts were seared on the engine block side. After consulting my mechanic and another, I was advised that 1) to repair the engine has to be lifted as the space between the firewall and the engine is too small to make repairs without lifting the engine ( manufacture defect) . Further, it was advised to me that completely sealing the manifold could lead to a fire in the catalytic converter because � these engines run hot�. As I expressed that this vehicles �antifreeze� level is not stable as I have experienced with other vehicles. In other words this vehicle burns up antifreeze quicker than I've seen occur in other vehicles. After researching the topic it was discovered by consumer reports that these vehicles have major defective engines with repairs to manifold being notorious. And to have to have the engine lifted each time is unreasonably costly. And I no longer feel safe driving this vehicle if a defective engine runs hot and there's a risk of fire. This is exacerbated by the fact of the tiny space between the engine and firewall within the vehicle.

I was having the struts and shocks looked at in my car. While the worker finished the job, he put the car down and took it for a test drive to make sure it was good to go. One that test drive, he said something did not seem correct. After he got it back to the shop and back on the rack, the frame was cracked and rusted through. This was not the case when my car was previously worked on by getting a new ball joint back in the fall of 2019.

The manifold and the catalytic converter is cracked and emitting hazardous carbon monoxide inside the cabin of the car. For close to 2 months my husband has been driving the car like this and we have taken it to 2 mechanics and finally found the cracks. My husband has been getting sick from the carbon monoxide. It is a blessing he is still alive. According to online google searches this is a well known issue in this vehicle. The smell is strong especially when he uses the remote starter and when the car is in motion and stationary.

I smelled fumes. The check engine light did not go on. I brought to my mechanic who said it had a cracked exhaust manifold. Co is leaking into my car. I will pay $1000 to have this fixed. No accidents. Just a faint smell of gas. I have 2 kids and routinely bring other peoples' kids into my car. Unacceptable GMC.

8/26/13 we took our Terrain into a GMC dealer due to check engine lite coming on, was informed that the manifold was cracked. Paid dealership to replace the manifold and all gaskets. Almost 4 years to the date the same repairs are needing to again replace the manifold. This vehicle is only 8 year old and is used for highway driving. We have been advised that this is a possible design flaw or there is a weaken motor mount.

Exhaust manifold cracked between cylinders 2 and 3 upstream oxygen sensor from hot exhaust gases from the leak passing on the wires and heater element within the oxygen sensor and exhaust manifold top heat shield. Carbon monoxide leaking through floor board.

"takata recall" so far at 140,000 miles on my 2010 Terrain I have had to put a new engine in, all 3 catalytic converters and now a power steering pump and rack. I could have bought a brand new car by now. No recalls on any of these??? there should be. The engine just stopped on the highway and once replaced then the steering became tight and barely made it to the shop.

I purchase my truck certified used and I already have to drop $1400 because the O2 sensor went out, the exhaust manifold is cracked and the hose that recycles the gas (I'm guessing the intake valve) is leaking! I still have to make car payments and insurance payments which total up to about $700 per month!!!! I am really dissatisfied as much as I love my truck.
