FUEL/PROPULSION SYSTEM
Fuel pump power control module failure. Part number 13554821. On [XXX], my trip home from South Carolina to Alabama was interrupted when I stopped to get something to eat. The car would not start and I had to call AAA to tow me to Superior GMC dealership in Anniston, Al. They knew what was wrong as soon as I told them it would not start. They already replaced three fuel pump control modules that day on the same model as mine. The service department said it was a persistent problem in GMC automobile's. I am [XXX] who had confidence enough in your automobile to take a trip by myself. I could have gotten stranded far away from home. I believe that this should be a recall because this is an ongoing issue with this model. I am sure that GMC is aware of this problem.

We have had 4 transmissions since we bought the vehicle. It slows down to almost a stop after it hits 30 mph and makes weird noises all throughout the vehicle. The back right tire sticks to the pavement and jerks when i start to drive. The key ignition has been fixed several times and still sometimes won't turn with the key or come out. Yes Warranty told the repaid service company to fix whatever, and they did but it still after 2 more transmission hasn't fixed the issues. Engine light and not sure what else.

SEAT BELTS, AIR BAGS
The "Service Safety Restraint System" warning light appears on the dashboard and warning chimes continually sound. To my knowledge GMC had a recall for this in 2018. I purchased the vehicle in 2021. I contacted GMC and told them this issue and they informed me that there are no recalls on the vehicle. My concerns being that airbags are fully functional.

AIR BAGS, SEAT BELTS
I was driving back home when I suddenly heard a loud pop and my car seat belt immediately tightened up. I saw smoke inside the car and the screen in my dashboard said "airbag service" There was no air bag physical deployed in the car so I believe it happened internally. Now my driver seatbelt will not retract and the front passenger seatbelt will not come out.

POWER TRAIN
Code p0700 was indicated at a professional transmission shop. My vehicle started driving different. It is a scary feeling. I have a ten year old daughter who I commute to school and safety is the utmost of importance. I don't want to have a accident in a vehicle I recently purchased for safety and end up having to look for another vehicle because of a total loss accident or a transmission problem that would cost a lot of money I don't have. My fear is the gears slipping as I drive my daughter to school. I got a quote of close to 3,000 $ to have the transmission rebuild or fixed. Money that I don't have to give a shop for a vehicle I purchased to not have problems like this. I called GMC to make an appointment to perform a transmission flush. The p0700 code indicates TCM failure. This is a very nerve wrecking situation. Please help me .

ENGINE
I bought a car from Boone Chrysler Dodge Jeep Ram dealership in North Carolina on [XXX] and by [XXX] my engine was out before I purchase my car I made sure they serviced my vehicle at a GMC Dealership and there's a warranty on the service of my engine I did not buy the warranty on my car because they couldn't guarantee that the warranty transferred over to West Virginia shop's and that they would cover issues they stated they could deny service cuz it was out of state. So my car went to Moses Cadillac GMC in downtown Charleston on [XXX] they literally just randomly dropped it back off to me two Wednesdays ago. I've been working with GMC to try to purchase a new vehicle and get mine bought back, but it's been a whole process but I'm trying to work with Moses so I can purchase a new vehicle but they won't call me back and i feel like its because they know something is defective. The engine had a Regen done before i purchased it and now all of a sudden the cars engine is Done. Now when this happened the battery got so hot my car started smoking we originally thought it was the starter. Because when it stopped working we were at a Toll booth and pressed the break and the stop start kicked the engine off and it never came back on. Even now if you try to start it the battery gets hot and the starter smokes. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
