I think FCA wastes a lot of money on licencing deals, for example the Batman edition Jeep Renegade, or 'partnering' with movies:

Subaru has long outpaced Jeep in critical areas such as earnings per vehicle. And the trend is getting worse:
In A Slowing Automotive Market, Subaru, Nissan Expected To Gain Share In 2017, According To Kelley
some quotes: "In the first five months of 2017, no brand lost more market share than Jeep. "
"In the past few years, the market has come to Subaru," said Kelley Blue Book Executive Analyst Rebecca Lindland. "Their brand is strong and their products are exactly what customers are shopping for. They've been smart with incentives, managing inventory very well." At current pace, Subaru could pass Hyundai in U.S. market share by the end of the year."
I would also remind people that FCA's idiot CEO Sergio spent a lot of time trying to find anyone to buy the company or merge with it. At the time he was saying that FCA as a whole was too small to go it alone Subaru was proving him wrong by selling every vehicle they could make and making a good profit on each vehicle.
