This is my 3rd Honda.
When you buy a Honda, you expect a solid car/good value...nothing complicated.
My 2011 Honda Accord 4dr has the same problem that started with in 2008 with the current generation...body creak due to a failed rear passenger weld joint. Plus, this car makes all sorts of weird sounds/creaks/groans.
Google and find out for yourself – many complainers.
Solution? Rip out interior panel and spray toxic lubricant on the interior area of the car.
Or bend the metal parts that are rubbing.
There is a TSB on point so Honda knows about this problem but is still making cars with the problem.
Not saying that you don't have a problem but I just "googled" as you suggested and found very few complaints involving defective welds in the current series Accords. I also consulted the NHTSA consumer complaint site at http://www.arfc.org/complaints/ and there were less than 5 entires concerning any remotely related complaint for the entire 2008-2011 series. We very much still like our 3rd Accord (2011 EX-L). Now, let me tell you about my 1982 Japanese-made Mazda B2000 pick-up sometime (if it had been a horse I'd have shot it in the head and left it on the roadside)!
