| Seat Belt problems |
2017 Cadillac Xt5 platinum. Seatbelt chime does not activate if the seatbelt is off while driving. Dealer says it is working as it is supposed to in this model year. !!!! please note that at the dealer we test drove for 3/4 of a mile, and the chime went off only after driving 4 blocks and making a right hand turn. It went off again seconds later and 1/2 mile later as we entered the parking lot, as we hit a bump into the parking lot, the chime went off again. My point is that the chime should go off at the beginning of the drive to remind the driver that the belt is off, not at the end of a 3/4 mile drive. Their answer is that they tested the seatbelt and no codes were detected. Since the chime did go off sometime during the drive, then there is no problem!!!! they claim they tested another 2017 Xt5 and it was the same!!! it worked for 8 years, but in the last 2 months, it started to fail with on the driver side. The passenger side later also started to fail, sometimes it will activate if no seatbelt was used, other times it did not. Today June 11, 2026 I tested the car and no chime was active. I also tested the rear seat and buckled & unbuckled while driving - no chime. I tried bouncing up and down on rear seat, and the chime went off! so the chime works but the car is not sensing when the seatbelt is unbuckled. I have grand children that ride in the rear using a car seat, if one of the seatbelts was unbuckled while driving, the chime would warm me that they took the belt off. We drove the car for 5 miles home and bucked and unbuckled the and passenger and the driver side belts at different times, and the chime did not go off. The light in the front panel does flash when the seatbelt is unbuckled!. Prior to the belt chime giving us problems, the same week the seatbelt on driver side tighten so hard while driving, that my wife got scared & even was afraid it would break her clavicle! we could not reproduce, but reported to dealer.
The contact’s father owns a 2020 Cadillac Xt5. The contact stated that while attempting to use the driver's side rear seat belt, the seat belt failed to buckle securely. The contact had not attempted to use the rear passenger’s side seat belt. The contact stated that the vehicle had not been taken to a dealer or independent mechanic to be diagnosed or repaired. The failure mileage was unknown.
I was involved in a front end collision with a car that pulled out in front of me without looking. I ended up t-boning the car at approx. 20-25 mph. Both myself and my wife were wearing our seat belts. Mine held but the passenger one held only the lap belt part. The shoulder part of the sb allowed her face to go crashing into the dashboard. She ended up with abdominal injuries and head trauma. I took it to the dealer and they say the seat belt will need to be replaced as it is defective. (you think). I can pull on the shoulder strap rapidly and it will not 'catch'.
The contact owns a 2022 Cadillac Xt5. The contact stated that the vehicle was equipped with the auto seat belt tightening feature. The contact stated that the feature tightened the seat belt to secure the occupant; however, the passenger’s side seat belt continued to tighten while driving at various speeds. The contact stated that his wife tucked her arms in between the lap belt and the seat belt tension was released. The vehicle was taken to the dealer where he was informed that there was no fault with the feature and that the feature operated as needed. The contact was also informed that the feature could not be turned off. The manufacturer had been notified of the issue but offered no assistance. The vehicle was not repaired. The failure mileage was 41.
