Yes that is your moisture sensor bar.

The drum is a part number 3045EL1002F which will set you back at least $135. Still well worth the repair, especially if you can install it yourself. You have to remove the top by removing 3 screws in back and sliding top back about 2 inches and lifting off. Then, remove front panel. Remove 4 screws holding the front bulkhead. Remove belt from drum. Remove drum. First time might take a hour, second one you do will take about 15 minutes.
Now, don't rate me down because you don't like having to repair your dryer. I didn't manufacture it. I'm just giving you a bunch of free advise.

Look for a crack on the seam of the drum, right at the front or rear of the drum.

If you are still looking for information on this:
No, there has not been any recall.
It is not a real common problem. I only see 1 or 2 a year, which is not many. (LE errors on washers are much more common, for example) The part number of the drum for a DLE2512W dryer is 3045EL1002D and lists for just over $100. You can find a service center to order the part from (in the US) at http://us.lgservice.com/index_b2c.jsp
I would rate the repair at about a 5 or 6 out of 10 on a scale of 1-10 in difficulty. (Basically, remove top, remove front control panel, remove front panel, remove front drum support, remove belt, drum comes out the front, reassemble.)

You have a problem with your dryer drum.  The seam weld has cracked and the drum needs to be replaced.  You will need to call a qualified LG technician to resolve this issue.

no problem with motor or control board. fault is with the motor capacitor only. this is often attached to the motor or near it. the value of the capacitor will be printed on it (usually about 8uf) and you should be able to source from an electrical spares shop
