Underbody Shield problems of the 1999 Dodge Caravan

The left hand strut tower on my 1999 Dodge Caravan has almost rusted through and I was told by mechanic that it is not safe to drive. Local Dodge dealer said this is not covered under any warranty or recall and that it's only a comestic problem. They want $2200 to repair which is more than value of vehicle. Everything I have read indicates this is absolutely a safety issue and would cause a crash if driving when the strut tower completely fails. Why is there not a recall for this well known and docemented safety problem?.

Driver's side strut tower has rust, which eventually could result in suspension-strut failure and loss of control while driving. Pictures available.

The consumer took the vehicle in for leakage under the motor. However, he found that the housing was broken.

While vehicle was being service and the technician noticed the left strut body has a crack and frame was rusted due to this problem. Please provide further information.
