Three Stellantis Models Among Slowest-Selling Vehicles In August 2025

Navigating today’s car market can be tricky, and knowing which vehicles are moving slowly off dealer lots can give buyers the upper hand. According to the latest dealer data from CarEdge.com, August 2025 has revealed the 10 slowest-selling new cars in the U.S., and three Stellantis models are among them: the Maserati Grecale, Dodge Hornet, and Alfa Romeo Giulia.

Market Day Supply (MDS) is the metric dealers use to determine how many days it would take to sell all the current inventory of a particular model if no new stock arrived. A higher MDS means cars are sitting on lots longer, which often gives shoppers more negotiating power. On the other hand, low MDS models typically command stronger prices due to limited supply.

For Stellantis, the standout is Maserati’s Grecale SUV, which currently has a 302-day supply. Dodge’s compact Hornet crossover comes in at 266 days, while the Alfa Romeo Giulia rounds out the Stellantis trio with 221 days. These numbers suggest that dealers may be more willing to cut deals on these models as they work to clear inventory.

Behind the scenes, slow sales are creating ripple effects in Stellantis’ European operations. The Cassino Assembly Plant in Italy, which produces both the Alfa Romeo Giulia and Maserati Grecale, has extended its downtime this summer due to a lack of orders. Meanwhile, Dodge has confirmed that the Italian-built Hornet will be suspended for the 2026 model year because of the current U.S. tariff situation, which has made importing the compact crossover more costly. These moves highlight how sluggish U.S. demand is directly impacting Stellantis’ global production footprint.

Interestingly, the list also highlights trends across the market. Nissan’s Versa tops the list as the slowest-selling vehicle in the country, likely due to its pending discontinuation. Even EVs like the Ford Mustang Mach-E are appearing here—not because demand has disappeared, but because Ford has ramped up production so much that supply now exceeds sales.

The average selling price for these 10 vehicles in July 2025 was $59,646, the lowest it’s been in months, signaling that higher inventories could start putting pressure on pricing.
