2023 Dodge Charger

The parking brake system on my 2023 Dodge Charger has repeatedly become loose and does not hold the vehicle securely. The vehicle has been taken to a Dodge dealership multiple times for adjustment or repair of the parking brake. After the most recent dealership service, the parking brake worked temporarily, but approximately one month later it became loose again and stopped holding the vehicle properly. The problem is especially concerning when the vehicle is parked on the sloped driveway outside my garage. Even when the parking brake is fully applied, the vehicle is not securely held in place and could potentially roll downhill, creating a safety risk to people, other vehicles, and property. The issue has been reproduced and confirmed through repeated dealership inspections and adjustments, but the repair has not provided a permanent solution. There were no warning lights or dashboard messages before the parking brake became loose. The main symptom is that the parking brake has little or no holding force when applied. The vehicle and parking brake system are available for inspection upon request. I am concerned that there may be a defect in the parking brake system because the problem continues to return after dealership service.
