NHTSA Complaint #11538445 — 2021 JEEP WRANGLER

The upper spring perch located at passenger rear is welded to the frame on one side and a crossmember on another. The two vertical welds failed with the remaining welds being at the top of the spring perch. The only indications of a problem were an occasional knocking sound when going over a bump and severe vibration coming from the rear of the vehicle. The noise was caused by the spring perch flexing and tapping the bottom of the body. I believe the welds broke early this year but the source of the noise wasn't found until July 2023. With prolonged use in this condition the spring perch can completely fail causing the spring and perch to fall out and make the driver lose control. The dealership submitted pictures and the manufacturer has agreed to replace the entire frame. There are a handful of other people that have reported the same problem (always on the passenger rear) but because of the design, I suspect as these vehicles age stress fractures in the weld will make this issue more prevalent.
