NEW YORK, Sept 30 (Reuters) – Two auto sector bankruptcies have rattled parts of the U.S. credit market, raising concerns about a deterioration in the financial health of low-income households and migrant communities.

Auto-parts maker First Brands became the latest company to unravel, filing for bankruptcy protection on Monday, following the recent bankruptcy of subprime auto lender Tricolor Holdings. While both companies had idiosyncratic reasons for their collapse, they have stoked fears of broader stress.
