Tikka is owned by Beretta... Their CS is horrible. Heard of a few Bergaras having some issues, as well...Chambers, firing pins, etc...
Anything man-made has a chance for being defective...Especially anything mass-produced. Nothing is perfect 100% of the time.
The only reason new Remingtons have to replace the triggers is because stupid people killed their family members or friends by their own negligence, and their lawyers took advantage of the crooked [in]justice system here in America, and sued them. So, now Remington has to produce crappy lawyer-proof triggers. So, everyone who complains about Remington's crappy triggers, or why they need replacing immediately, they can blame the dumbasses that killed their friends and family members from their own stupidity and negligence, and then blamed Remington. And to keep from getting sued himself, Mike Walker had to "admit" that the old triggers were "defective" on camera in a 60 Minutes interview. Which I thought was complete crap, and nothing more than an anti-gun propaganda hit piece.
