2018 COACHMEN PRISM Complaints

2018 Coachman Prism 14K miles. I've always had issued maintaining the correct air pressure in my rear tires. On 3/3/23 I took my RV to Discount Tire to have my tires checked. The technician pointed out where the rims were leaking at the welds. This same defect was observed on the wheel next to it. Discount Tires has provided a written statement of their findings. I called the service advisor at my local sprinter dealer; they informed me that this issue would NOT be under warranty. Although my tires appear to be in good condition, the effects of running tires on low pressure could significantly reduce tire life and increase risk to operator and passenger safety. Currently there are 6 Complaints submitted for the same issue. At what point does this get escalated to an investigation?
