The driver's side seat belt is slow to retract or doesn't retract at all. Started back in May 2022, one month after the warranty expired with less than 20k miles on it. Originally, Mercedes Benz of El Cajon said they would fix, then declined. We called MBUSA and opened a ticket 2-33281290644 and they said set up the same repair with another local dealer and give them this ticket number. We did and after several delays by the second dealer, Mercedes Benz of San Diego, we were told MBUSA denied the warranty claim and that they could only fix it if we paid $749.49 which includes $298.80 for Labor, $418.27 for parts and $32.42 for taxes. This seems out of line and we are now more than 6 months…
