While slowing down to make a turn on side road, the lower left control arm pulled completely out of the frame. Inspection after found large hole rusted completely through the frame rail. Inspected right side and frame has same type of rusted and missing frame segments. Thankfully this happened at low speed and not on the interstate where outcome could have been very bad. Doing some research I have found that this appears to have been a known problem with this model for several years beginning with 1999 model.

When driving to work the wheel start to pull. When I got to work I took a look at the frame there was a 2 inch crack in one side and a 1/4 inch by 20 inch crack in the other side. When I touch it the frame was rotten.

Vehicle began knocking as if something hit it from underneath. Also, steering suddenly was out of alignment and front end felt very loose. Mechanic discovered a hole in subframe approx. One foot in size due to excessive rust/corrosion on passenger side. As a result motor is loose and vehicle is very out of alignment. Mechanic said he has seen this three times on this model only; also said that frame design is such that water collects on top and cannot drain. Vehicle is 2000 and only has 66,000 miles. Apparently this is happening to this make/model of certain years, yet no tsb's or recalls have been issued.

Noticed at last oil change, potential structural failure of front sub frame/engine cradle due to rust out caused by design that allows water to enter and be trapped in sub frame. Cars in "snow belt" areas (Ohio) are affected by road salt. Sub frame has 2.5" rust hole and surrounding area shows fatigue and cracking. Car appears to be one "chuck hole" away from failure.
