Major auto groups are uniting in a rare effort to lobby the Trump administration against proposed tariffs on car parts, warning that such measures could lead to layoffs and bankruptcy within the industry. As prices for both new and used cars are expected to rise significantly due to these tariffs, analysts predict a potential dip in car sales by up to 2 million units in the U.S. and Canada. The tariffs could push the average price of new vehicles past $50,000, compounding the impact on consumers who are already struggling with increasing insurance rates. With car buyers racing to make purchases before the price hikes take effect, many are concerned about dwindling vehicle supplies. Additionally, the tariffs threaten to escalate costs across the board, not only affecting car sales but also influencing auto repair expenses and finance policies.
