I'm repeating words that the bike shop told me or from a google search. This bike seems to be defective since purchase. It's a Schwinn Men's GTX3 Hybrid with 700c wheels. Within a few weeks the pedals started to degrade and would randomly make little clanking sounds or have a scraping feeling only for a second here and there. The pedals and the gear wheel started to wobble increasingly worse and worse until it seemed like it would fall apart with any pressure.
It looked like the interior part of the frame that the pedals connect to was the problem, as if it degraded or was breaking down. Google said this is called the crankset so I'm going with that term.
This was from a Dick's Sporting Goods, which is the only bike related store and shop anywhere near me sadly. Being a corporate chain it seems low quality, and it's hard to find good bike parts, repair, info. They've repaired this 3 times now (supposedly) in 6 months. The first repair didn't even fully fix the issue, it wobbled but was improved. The last time seemed fully better but it only lasted 3 days before rapidly degrading. They claim the bearings and brackets need to be replaced each time; this last time I told them to look for other problems but they were extremely disorganized. I'll be going longer distance to find a legit local bike shop.
I just want to know what is actually wrong with the bike, the right names of parts and what needs to be replaced/repaired. Is it defective? It has a 1-year manufacturer's warranty and it's the most expensive bike I've ever bought (supply chain failures presumably).
