Is there a fix? Manufacturer service bulletins

Stop at a red light the fuel peddle got stuck would not accelerate. Finally the mariner started moving then had to come to a stop for stop sign same thing happened. Took it to the shop said the "throttle" was broken on this. This is a very dangerous can't drive it with the throttle being broken. Never had a problem with a throttle on any of my pass cars. Tracer,ls mustang I have these cars over…
Vehicle sub-frame broke at point where lower control arm attaches, causing Right front wheel to suddenly turn right. Sub-frame rusted through!
The front sub-frame has completely rusted out. We live in a salt zone (michigan). There is also visible corrosion throughout the exterior. We were driving and the front passenger wheel started bowing out and we started vibrating. We got to safety before anything happened.
My vehicle: 2006 mercury mariner hybrid SUV. Purchased new in 2006. In hot weather...vehicle engine quits while in motion on freeway at approximately 70 MPH (3 times), and city streets (3 times). Extremely dangerous when engine quits while driving on freeway in traffic. All you can do (while praying!) is coast to a stop and do your best to pull off on to shoulder of road without crashing…
