    I think the manifold on GMC Terrain need to be on a recall because mine already cracked.

    Evap emission control leak detected As the check engine light comes on, when hooking a computer up to the car for a scan it pulls a code stating there is an evap leak. The gas cap has been replaced along with a sensor and no gas is seen leaking but you can smell gas vapors when the car is running and fuel mileage is terrible. Also the stabilitrak has been an underlying issue since owning the vehicle

    It appears the timing chain is bad. The vehicle only has 84000 miles and currently the engine turns off and you just coast to a stop in the middle of driving.

    Took vehicle into dealer for a recall on October 17, 2023 with the recall being [Primary]: RECALL : C/S: N192268181 -TAILPIPE EMISSIONS - EXHAUST COMPONENTS: C/S: N192268181 -TAILPIPE EMISSIONS - EXHAUST COMPONENTS. The dealership did an excellent job on the work providing a video to show work being done. Now this month of April, I received another check engine light stating the P0013 code stands for “Exhaust “B” Camshaft Position Actuator Circuit/Open (Bank 1).” There is not a recall from the manufacturer but according to dealership they've received a bulletin in regards to this issue. According to the dealership it will cost in excess of $500 to repair. Absolutely not true. There are a thousand videos on what causes this and even how to repair it from the same mechanics that work within these dealerships. This issue is a safety issue because if not repaired it causes damage to your engine. This code lets you know that you will start experiencing loss of power, trouble starting your vehicle, the stalling/picking up speed all at the same time. Some of these issues have been caused from the issue of the oil consumption problem associated with the Terrain's.

    My vehicle is 2012 GMC Terrain. Oil changes on my vehicle we kept up and i had no major issues with this vehicle. I had an oil change done about a month before i went to start my car and all the lights came on and my car would rumble and wouldn't stay started and was longer drivable. After towing it a service shop they stated the following: The timing chains are damaged, skipped teeth, metal debris found in oil and screen of intake and exhaust camshaft solenoids due to many oil leaks coming form engine and serious internal issues w/engine we recommend replacing the engine. Est cost, 11,061. I had no reason to think my car was in any trouble, as it was driving fine with no problems. I received no such recall letter or phone call and no mention from the dealership i bought the car from back in 2018 that this was an issue or that it was "taken care of" if I had i wouldn't have paid over $20,000. into my car. Reading several complaints online about this exact issue is all new to me. Knowing i could have been driving a vehicle and it could have started a fire in my engine is crazy to think. Because I may have been driving a car with a serious recall on it. I am at a loss right now, financially i am screwed.
