Gosh, do worry about my post. If you really want a Challenger go for it. Most if any problems that will occur I am sure DCX
will have a solution for the problem. You are right that since so many components are being used there should be minimal problems.
I believe the LY platform is identical but just about 4" shorter that the LX.

Most of the time unless it is a hazard or a danger the recalls will not be in the press but in the form of a letter to the owner. Whether problems are discovered
in the first year depends on how senstive the problem is to miles and time.

Granted the $140K Ford GT was a short lived car and the parts were not used on other platforms but you may find the report below interesting:

Problems
Early production Ford GT experienced a few minor problems (including glitches with the electrical and climate control systems, leaking power steering and engine coolant hoses, and a steering column rattle on some cars), and two bigger problems.

In December of 2004, Ford recalled all Ford GTs that had been built up to that point (448 units were built, but only 283 had been shipped to dealers, and only 106 had been delivered to retail customers) because of concerns regarding the strength of the suspension control arms. They had been "squash cast" for added strength, a new process also used by Porsche and Alfa Romeo. But after Ford discovered a crack in one of the high-mileage development cars, the company decided to replace the parts on all the production cars. Ford is not the only manufacturer of exotic cars to have such problems, for example, a similar problem was found on the Ferrari F40.[3]

There was also a TSB (Technical Service Bulletin) to inspect the engine on early cars built in 2004 for an oil leak at the main seal. The finish of some crankshafts was flawed, causing an oil leak. Ford dealers stopped the leak with a new main seal and a "Speedi-Sleeve" around the crankshaft, a device commonly used to repair worn engines in older cars. Some journalists felt that this was an improper fix for an expensive supercar and criticized Ford for not either replacing the defective crankshaft or replacing the entire engine.

There are a few other TSBs for the car. TSBs are Technical Service Bulletins that help eliminate problems that some cars may have. The Ford GT TSBs show that some cars may need hose clamps adjusted or replaced, and a few other tiny problems. They are also issued to inform repair shops how to repair paint damaged by acid rain, etc.

Like I said, if you want a Challenger go for it and of course the flip side other than minor problems that will be fixable, the first year will probably be collectibles some day. I hope that gets rid of your doubts and builds your passion back up for the awesome muscular looking Challenger.
