Seat Belt problem #1

The front passenger side seat belt retractor is failing to retract. I had a passenger in the vehicle and as we came to a stop in my driveway to exit the vehicle she unhooked (released) the seatbelt and it will not retract. The seatbelt is now currently extended out and will not retract back into the retractor. I purchased the vehicle today 08-05-2026, I called the dealer I purchased it from and they state that there is no recall on the vehicle with this issue. I did look the issue up on google and infact is states a problem with the seatbelt retractor for my vehicle. I sent them a screenshot of the confirmation found and they decline to acknowledge a repair stating there is no recall. I was able to manually feed the belt back into the retractor, it was extremely difficult but I sat in the seat to duplicate the issue and it will duplicate. The seatbelt is currently extended and will not retract automatically. The shoulder stap will not fit securely around a passenger at this time. I have had no prior use of the vehicle until today as I purchased it from a reputable dealer who states they did a full inspection of it prior to selling but apparently this issue was not repaired prior to selling it.

Seat Belt problem #2

The middle rear seatbelt fails to lock when retracted, therefore I cannot use my grandchild's booster seat. The dealership has ordered a replacement, but cost nearly $300. I bought the vehicle new in December 2018, but have never had to use the real seatbelt until now. Therefore I did not know it did not work properly until now.

Seat Belt problem #3

Driver's side seat belt receptacle does not hold. It is difficult to get seatbelt to latch properly. Sometimes it latches and releases later. Dealer confirmed seat belt receptacle needed to be replaced.

Seat Belt problem #4

The contact owns a 2018 GMC Sierra 1500. The contact stated that the seat belt straps for the rear driver’s and passenger’s side seats would no longer retract and were stuck between the seat cushions. The cause of the failure was not determined however, the local dealer informed the contact that the seat belt retractors were likely defective and would need to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 60,000.

Seat Belt problem #5

The back middle seatbelt broke shortly after the vehicle was purchased new.
