Defect Description:

STRUCTURE:BODY

Potential Consequences:

The strike plate on my rear driver door fell off. The plate and bolts are in perfect condition but the backing is gone. Multiple body shops have attempted to locate the backing, which is somewhere between the interior and exterior metal body pieces, and gave been unable to. Every body shop I've taken it to also says that they have never seen anything like this happen before. They are reluctant to fix it because that would mean cutting through the body to replace the backing for the strike plate then welding, sanding, and painting in the area they cut and they worry about the integrity of the striker and functionality of it as well, as they've never had to do a repair like this before. One of the body shops was also a certified GM repair shop at the dealership from which the car was purchased and even they have said the same as the others. They also encouraged me to report this to the NHTSA and GM as well because they've never seen it happen or heard of it happening and they are concerned because it is a safety issue. I know that there is a similar recall on some newer GMC Terrains and wonder if my issue would be related to the recall or if it's is a separate issue all together. The striker was barely touched and someone exited my back seat and fell off into a parking lot, I was able to recover the striker and both bolts which are completely undamaged and unworn. This is my only vehicle so I now have to hold my door shut with bungee cords and tape in order to use my vehicle. I have a child who is still in a car seat and must remain in the back seat for safety but now my backseat is also not very safe because of the door. A few days prior to the striker falling off my door would not close fully flush with the rest of the vehicle but still closed, locked, and remained closed with no other issues.

SERVICE BRAKES

Potential Consequences:

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.

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.

Additional Notes:

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.
