A double-digit decline at Stellantis' biggest brand, Jeep, led the automaker to a 6.4 percent decline in third-quarter U.S. sales.
The company's top sales executive, Jeff Kommor, blamed the company's latest results on "challenging industry supply constraints."
Jeep was hurt by a 53 percent slump in deliveries of the Grand Cherokee, its biggest seller, during the latest quarter.
Stellantis' No. 2 brand, Ram, also posted a decline during the period on slightly weaker pickup deliveries. Jeep and Ram sales have now dropped five straight quarters.
One bright spot: Stellantis said commercial shipments rose 57 percent during the quarter, without providing details.
