Some automotive chips are under renewed pressure, but available evidence does not establish that a broad shortage like 2021–2022 is inevitable. The clearest current concern is older automotive memory: buyers face tighter options and higher prices, while deeper supply-chain vulnerabilities could make particular vehicle programs harder to build. That is a serious risk, not a forecast of widespread factory stoppages.
The distinction matters. Automobiles use many chip types, made with different processes and supplied through different chains. A constraint in one category can raise costs or delay a specific model without leaving every automaker short of chips.
Is another chip shortage coming for automakers?
It is possible that automakers will face further targeted shortages, but the evidence available as of October 4, 2026 does not show that a crisis on the scale of 2021–2022 is imminent. The current warning signs are uneven: older automotive DRAM has faced price and supply pressure, and industry analyses identify dependencies that can be difficult to replace quickly. Neither point establishes the timing, breadth, or production impact of a new shortage.
S&P Global Mobility’s May 2026 analysis described automotive-grade DRAM supply as available to buyers willing to pay more, framing the issue as a planning challenge rather than a current volume crisis. That status is specific to its May assessment, not a live October inventory check. Automaker exposure can change with suppliers, chip generation, production plans, and the ability to qualify alternatives.

Which chips are under pressure—and why does the category matter?
“Automotive chips” are not one interchangeable commodity. MCUs, memory, analog chips, logic and power semiconductors have different uses and supply dynamics. The Federal Reserve Board’s September 2026 account of the previous shortage illustrates the difference: microcontrollers (MCUs) were the dominant category in its analysis, while lead-time increases varied by category and optoelectronics were largely unaffected.
| Category or pressure | What the evidence says | Why automakers may care |
|---|---|---|
| Older automotive DRAM, including DDR4 and LPDDR4 | S&P Global Mobility’s May 2026 analysis reported tightening options and rising prices. It specifically described automotive LPDDR4 prices by January 2026 as up around 70% year over year. | Higher costs or fewer sourcing choices can complicate purchasing and planning even if chips remain available. |
| MCUs | The Federal Reserve Board’s retrospective identifies MCUs as the dominant category in its analysis of the 2021–2022 shortage. During that episode, MCU lead times rose from 15 weeks to 30 weeks, with increases beginning in late 2020. | Past MCU constraints show how a shortage in a specific category can become a production problem; they do not establish that the same category will lead the next disruption. |
| Analog, logic and memory more broadly | The Federal Reserve Board found elevated lead times in these categories during 2021–2022, to varying degrees. | Supply conditions and the consequences of a constraint differ by chip and application; a single industry-wide shortage label can hide those differences. |
| Advanced compute and power electronics | S&P Global Mobility’s April 2026 analysis links rising automotive demand to electrification, advanced driver-assistance systems (ADAS) and software-defined vehicles. | New vehicle architectures add semiconductor requirements, but demand growth alone does not prove a physical shortage. |
S&P Global Mobility says data-center demand for high-bandwidth memory is drawing capacity toward that market, adding pressure to automotive-grade DRAM and NAND. That is one part of the supply story—not proof that AI demand alone has caused an industry-wide auto-chip shortage. Automotive buyers can also have fewer alternatives when a vehicle depends on an older memory generation.
Why can’t automakers quickly switch to another supplier or chip?
A chip shortage is not solved simply by finding a similar-looking component. A replacement has to be available in the required category and generation, fit the vehicle’s design, and be qualified for use. Changing a component or architecture can take time, particularly once a vehicle program is under way.
ACEA’s September 29, 2026 summary of an EY study focuses on Europe’s automotive value chain. It describes concentrated supply across countries, suppliers and processing hubs, alongside limited alternatives and long development and qualification lead times. ACEA summarizes the finding this way: “The greatest risks stem from the concentration of supply across a limited number of countries, suppliers and processing hubs, combined with limited alternatives and the long lead times needed to develop new capacity.” This is evidence about European dependencies; it should not be read as a map of identical exposure for every global supply chain.

New capacity takes years to come online, while a particular vehicle program may need a specific part much sooner.
How could chip constraints affect cars and buyers?
The last shortage shows what can happen if a constrained chip becomes essential to a vehicle’s build. In its September 2026 historical analysis, the Federal Reserve Board calculates that the cumulative U.S. light-vehicle production shortfall exceeded 2 million vehicles over 2021–2022 against a 2020 Q4 output baseline. Production did not recover to pre-crisis levels until early 2023.
Automakers tried to keep production moving by directing scarce chips toward higher-priced, higher-margin vehicles and deleting chip-intensive features. Those choices could protect output while narrowing access to less expensive models or reducing equipment. The Federal Reserve cautions, however, that chip needs depend on powertrain, electronic architecture and installed features—not simply a car’s sticker price. A premium vehicle is not automatically more vulnerable, nor is a lower-priced vehicle automatically safer from cuts.
A future constraint could first show up as higher component costs, tighter purchasing choices, a delayed vehicle program, or a feature change rather than an immediate plant shutdown. Which outcome occurs would depend on the part in short supply, whether a qualified alternative exists, and how much flexibility the affected vehicle’s design allows.

Is growing chip demand the same as a shortage?
No. Rising demand can make supply planning more difficult, but a market forecast is not a measure of available inventory. S&P Global Mobility forecast automotive semiconductor revenue growing from around $90 billion in 2025 to about $139 billion in 2031, a 7.5% compound annual growth rate. The forecast reflects a growing market; it does not predict that automakers will be unable to obtain chips.
The Semiconductor Industry Association projected global chip sales would exceed $1.5 trillion in 2026. That is broad semiconductor-industry context, not an automotive availability statistic. Both forecasts underline the scale of demand and investment without establishing an auto-chip production shortfall.
What can automakers do to reduce the risk?
Resilience depends on decisions made well before a supplier misses a shipment. ACEA’s study summary recommends a combination of broader supply partnerships, targeted investment, better supply-chain monitoring, faster permitting and qualification, and credible long-term demand signals. For an automaker, the practical objective is to find vulnerabilities early enough to act—not to assume every chip can be swapped at short notice.
- Map dependencies: Identify critical parts, suppliers and processing steps, including where alternatives are limited.
- Plan alternatives early: Consider supply options and qualification during vehicle and electronics planning, when design changes are more feasible.
- Monitor categories separately: Track the specific chips and generations a program needs rather than treating all semiconductor capacity as interchangeable.
- Balance feature and production choices: If supply is constrained, assess which builds or features can be adjusted and what that means for customers.
These measures can improve options, but they cannot instantly create a qualified replacement or bring new capacity online. That is why early visibility and program-level planning matter.

What should car buyers take from the warnings?
There is no basis here for assuming every car will become scarce or that another broad production crisis is certain. The more defensible conclusion is narrower: older automotive memory has faced documented price pressure, and concentrated supply chains can leave particular parts or vehicle programs exposed. The 2021–2022 experience shows how production and equipment can be affected when critical components are unavailable, but it is a historical example—not a prediction that the same disruption will recur.
