Why are new car prices holding steady?
New cars & trucks: +0.6% in the 12 months to September 2026 (U.S. Consumer Price Index), versus +3.7% for prices overall. 1-month +0.1%, 3-month +0.3%, 5-year +12.2%.
Inflation check: Rising slower than inflation. +0.6% in a year, versus +3.7% for prices overall (0.2× the overall rate).
The short answer
- New vehicle transaction prices rose just 0.6% over the year to September 2026, lagging overall inflation of 3.7%, because normalized factory supply and replenished dealer lots forced automakers to maintain elevated sales incentives. [1] [2]
- Persistent auto loan interest rates have restrained consumer purchasing power, keeping vehicle price movements flat over the last three years after the severe chip shortages that drove a 12.2% price increase over five years. [3] [4]
What's driving the price
Political, regulatory and trade factors
- Sustained high borrowing costs dampening buyer demand (Mar 2022 to Sep 2026), Federal Reserve: The Federal Reserve maintained elevated benchmark interest rates, which drove auto loan rates higher and forced dealers and automakers to offer heavy financing subsidies to keep monthly payments affordable. [pushed prices down] [3] [7] [9]
Macro factors: supply, weather, disease, energy
- Dealer inventory replenishment (Jan 2023 to Sep 2026): Available new vehicle supply on dealer lots climbed from pandemic shortages to 2.66 million units at year-end 2023 and topped 3.0 million in late 2024 according to Cox Automotive, eliminating dealer markups above manufacturer suggested retail prices. [pushed prices down] [2] [5] [6]
- Pandemic-era semiconductor and supply chain shortages (Oct 2021 to Dec 2022): Severe global semiconductor bottlenecks and factory shutdowns sharply reduced vehicle assemblies, creating inventory deficits that drove the bulk of the 12.2% five-year price gain. [pushed prices up] [4]
Retail, brand and seasonal factors
- Expansion of automaker incentives and discounts (Dec 2022 to Sep 2026): Automaker incentive spending rose from an all-time low of 2.1% of average transaction prices in September 2022 to 5.5% in December 2023 and 8.0% by December 2024 according to Kelley Blue Book, offsetting baseline cost pressures. [pushed prices down] [2] [7] [8]
- Automaker production adjustments and higher-trim mix (Jan 2024 to Sep 2026): Automakers contained excess inventory by trimming factory shifts and temporary downtime, such as Stellantis shift cuts at Jeep plants and Ford reducing electric truck output, while prioritizing higher-priced SUVs and trucks to preserve price floors. [pushed prices up] [5] [7]
Supply chain right now
- Raw materials and component manufacturing (stable): Parts manufacturing export prices rose 2.8% through 2025 according to the U.S. Bureau of Labor Statistics as pandemic supply constraints fully resolved. [4] [10]
- Vehicle assembly and logistics (stable): Manufacturers maintain calibrated production shifts and holiday downtimes to keep overall production in balance with steady consumer demand. [5] [6]
- Dealership inventory and financing (moderate): Dealer lots remain stocked near 3 million vehicles while high auto loan rates force sustained retail discounts to move inventory. [3] [6]
