I'm not aware of any recalls for this reason, but this point hits on the advice I gave a new forum member a couple days ago who decided he was going to use his older tracker for a snow plow and was going to buy a newer generation Suzuki/Tracker for his DD. He asked for some things to look out for when he went shopping for his new truck.
For some reason, the manufacturers, the dealerships, and a lot of owners are not compelled to protect the frame and bodies on their Trackers/Suzukis from rust and corrosion (undercoating).
You can always repair or replace a ruined transmission or engine. But the frames, crossmembers, and supports are forever and a lot more expensive to repair when their foundation is gone.
I've used the "Herculiner" product (it's like the truck bed liner stuff) on my last three trucks. Before I buy them, I eye-ball the frame and components to ensure they are not excessively rusted. If they are, I pass on the truck. When I finally buy one, I drive it home, park it on jack stands and begin sanding the corroded areas on the frame down to metal, then I wipe off the metal with Xylol and apply the Herculiner with a roller or use a small brush in the tight places. Two coats at least. I also tape off the rocker panels under the doors take my electric palm sander and rough these areas up as well, wipe them off with Xylol and Herculine them as well. I put three coats on the rocker panels to withstand thrown rocks. I also coat the inside rocker panel, floor bottom and outside frame rails and cross tubes with the Herculiner. This area is where all the rocks, salt, and crap gets thrown under the truck from the tires. After the Herculiner is applied, the surfaces are almost bullet proof to moisture, mud, salt, and rocks. I don't have to worry about them any more.
I also sand down and coat the front cross member cause the bottom of this area catches ALL the road debris, rocks, salt as well. In fact, I have only bought one Suzuki/Tracker (out of the seven I have owned) that didn't have some serious rust on the front cross member area. As you pointed out, this member carries alot of the truck. Steering, radiator support, etc. I sand and coat the bottom of this area with the Herculiner as well. I only get the bottom, front, back and sides because the top is too difficult to completely cover and has a lot of small crevices I can't get too without getting the Herculiner all over a bunch of components I don't want it on. The top doesn't catch all the thrown rocks and salt either.
Two small draw backs come to mind using this stuff. First the Herculiner, once dried, is on there for virtually ever. This is also true of your skin. You can't wash it off. You "wear it off" over a period of time and showers. So be sure to wear an old long sleeve shirt and pants that you intend to use as rags afterwards. Second, the Xylol is a very serious chemical and you need to handle it very carefully, wear heavy rubber gloves and ALWAYS apply it in a very WELL ventilated area. A quality resperator probably wouldn't hurt either. I have no doubt if I wasn't shooting blanks now, that any new kids I would sire would come out with two heads and four eyes.
Honestly, I spend about 8-10 hours per truck cleaning and applying this stuff when I first buy them. A lot of time for sure, but I still think it is time well spent. Plus I spend some quality time with my trucks really looking at the under carriage and drive train.
Oh, yea, and I don't work for Herculiner nor do I sell it. I buy it at Meirs for about $28 per quart. It comes in black, blue, red, and gray, but I can't find anyone who stocks anything other than black. You can special order the other colors, I'm sure, but I'm in it for the protection and black works for red, blue, and burgandy color trucks just fine.
So... you can order a new cross member (if your ride is in good enough shape to warrant the expense and effort) coat that baby with something like Herculiner, and it will hang with you forwever unless you wrap it around a tree.
