Module malfunction open-fuel pump driver control. Engine stops at any time, pressing gas pedal and nothing, the engine stops running no warning. Module has been replaced twice this vehicle should be on recall. When it happens you have no warning and no control. This is life threatening.

Every time it rains, the floorboard of my car is soaking wet. I took it to the dealership, and they stated the leak is coming from inside the firewall. I have only had this vehicle for 2 years and just recently moved to a house without a garage. Now that I am just now noticing it, I am wondering if it was like this when I bought it, but I am only noticing it now that I do not have a garage. They want to charge me over $1,000 just to take apart the dashboard to find the leak and that is just insane. There is no telling how much mold, rust, etc. could be in my car from this leak.

SERVICE BRAKES
I have a 2018 Terrain SLT. On 11/20/24, I was headed home from my commute to work driving my terrain with all the confidence in the world because I hadn't had any major issue with it. In 5pm stop and go traffic I decided on another route to my son's school to pick him up from practice. As the light at the end of the bridge turned red, I proceeded to stop, and my brake pedal was as stiff as stone. Going across that bridge I was literally standing up on the brake pedal with my back and shoulder against the roof of the truck for support trying to stop. As I came close to the cars that had already stopped I contemplated jumping out of the car but I decided to keep at it. It was God and God alone that cleared a shoulder for me to be able to pull over. I was petrified!! No signs, no brake noises, no hesitations, nothing! No warning lights on the dash, no alerts, NOTHING! Brakes were just gone! The mechanic said the vacuum pump had exploded and it was a known issue with terrains and that there was a bulletin regarding this. Pieces of the metal from the exploded vacuum pump were found inside of the engine. The mechanic was upset about the event and said to notify GM, something needed to be done about it. He gave me the vacuum pump to show the GM service center and he said one of the mechanics took pics of the metal in the engine. I called GM and was told to bring it in to a GM service shop so that they could check it out, but at my expense because the manufacturer warranty had expired. I AM SO UPSET WITH GM!! I have anxiety every time I go to press the brake! Panic attacks thinking about the possibility of this happening with my kids/elderly parents in tow. Thank God for covering me and all the drivers and their families that could have been hurt. Thank God my son/elderly parents weren't in the car! The fact that this is a known issue and it hasn't been addressed is heartbreaking. GM should do the right thing and recall these trucks, asap.

SERVICE BRAKES, ELECTRICAL SYSTEM, STEERING
My ESC randomly comes on. Service parking brake message comes on intermittently. Messages pop a up saying steering wheel assist limited, drive with care. Again, all of these are intermittent but when they happen my steering wheel locks up. Even mid turn. Being intermittent it doesn’t always happen and weather seems to affect when it happens, or that’s a coincidence.
