I have a 06 Dts Luxary 3, I am having problems with my seat belt warning chime. I always buckle my seat belt before starting the car. When starting the car some times the chime works properly. Many times it will chime once, occasionally it will chime 3 or 4 times. I have taken the car in several times explaining what the chime does but the dealer keeps telling me there is no problem. I have even had a service writer tell me it was the front parking sensor which is a totally different sound. Is anyone else having having this problem or know of a service bulletin or repair to correct this. I know it's not major but is something wrong and for what we pay foir these cars it should be corrected.
