“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.”
NHTSA complaint #11511148, filed 2023-03“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. …”
