what stellantis plants are on strike
As of the latest reports, the Stellantis plants directly affected by strike action or strike-related shutdowns have been:
- Poissy plant, France – production halted due to a strike at key supplier MA France.
- Hordain plant, France – also halted for the same supplier strike.
- Luton plant, United Kingdom – van plant shut down temporarily because of the supplier strike; later faced longer‑term closure pressure.
- Sterling Heights Assembly Plant (SHAP), Michigan, USA – 6,800 UAW workers walked out here in late 2023 as part of the “Stand Up Strike,” shutting down Stellantis’ biggest profit center for Ram 1500 pickups.
These actions span different moments (mainly 2023–2024) and different types of strikes: some at Stellantis plants themselves (like SHAP with the UAW), others at a supplier (MA France) that forced Stellantis to halt production at multiple factories.
Quick Scoop: What Stellantis plants are on strike?
If you’re trying to understand “what Stellantis plants are on strike” right now, you’re really looking at a rolling story that has unfolded in waves since late 2023.
First came the high‑profile United Auto Workers (UAW) actions in the United States, and then a separate, but very impactful, supplier strike in Europe that effectively froze production at several Stellantis sites.
Key plants hit by strikes or strike‑driven shutdowns
1. Sterling Heights Assembly Plant (SHAP), Michigan, USA
This one became the headline symbol of the UAW’s confrontation with Stellantis
in 2023.
- About 6,800 UAW members walked off the job as part of the “Stand Up Strike.”
- The plant builds Ram 1500 pickup trucks, a core profit engine for Stellantis in North America.
- When SHAP went out, it wasn’t just another plant; it was a direct hit on Stellantis’ most lucrative vehicle line.
In union circles and auto forums, SHAP became shorthand for “the moment Stellantis really started to feel it,” because shutting a high‑margin truck plant turns a labor dispute into a financial crisis.
2. Poissy, France – Stellantis plant Poissy didn’t see its own workers strike first; instead, it was collateral damage from a supplier battle.
- Production halted after a strike at MA France, a key stamped‑metal supplier.
- The stoppage began around mid‑April 2024 and quickly forced Poissy to suspend operations.
- This plant produces compact vehicles for Stellantis brands and is a big employer in the Paris region.
Because of that supplier action, Poissy illustrates how a modern car plant can be brought to a standstill even when its own workers are still ready to build cars.
3. Hordain, France – Stellantis vans plant Hordain is another French Stellantis site that got dragged into the same storm.
- Like Poissy, Hordain had to stop production due to the MA France strike.
- The factory builds vans and minibuses, including models for both Stellantis and Toyota.
- The shutdown hit not just Stellantis’ own brands but also its partnership business.
In European auto forums, Hordain is often mentioned as a sign of how fragile multi‑brand, multi‑OEM supply chains can be when a single supplier goes down.
4. Luton, United Kingdom – Stellantis van plant Luton’s story is a mix of immediate strike impact and longer‑term strategic decline.
- This plant was one of the three factories where production halted due to the MA France supplier strike.
- It builds vans for Stellantis brands and has a long industrial history in the UK.
- Separate from the strike, later reports and analysis described the Luton plant as facing serious risk, with eventual closure and job losses becoming part of a broader Stellantis restructuring narrative.
For many workers and union voices, the Luton stoppages were a warning flare that temporary strike‑related shutdowns can accelerate permanent industrial decline if the company is already considering pulling back.
Why these strikes happened
The phrase “what Stellantis plants are on strike” actually refers to two different types of conflict :
- Direct labor‑management disputes at Stellantis plants
- Example: UAW’s Stand Up Strike in the US, including SHAP.
* Main issues: wages, benefits, job security as EVs and automation reshape the industry.
- Supplier‑side strikes that indirectly shut Stellantis plants
- Example: MA France workers striking over job security and the future of their plant.
* Impact: Stellantis assembly plants (Poissy, Hordain, Luton) ran out of critical stamped parts and had to stop.
From Stellantis’ perspective, both kinds of disputes hit production and cash flow, but supplier strikes add a layer of unpredictability because Stellantis doesn’t control those workers directly.
From unions’ perspective, targeting a vital supplier can be a powerful lever, because the ripple effects multiply across several high‑value plants at once.
Different viewpoints on the Stellantis strikes
To get a fuller picture, it helps to see how different sides talk about these actions.
- Worker and union view
- Strikes at SHAP and the MA France supplier plant are framed as necessary to defend real wages, future jobs, and investment promises.
* A recurring theme: Stellantis is making strong profits while plants face layoffs, temporary closures, or fears of production moving to lower‑cost countries like Poland.
- Stellantis management view
- Publicly emphasizes “regretting” disruptions but insisting on competitiveness, flexibility, and EV transition challenges.
* During the MA France strike, Stellantis expressed hope that negotiations at the supplier would allow quick resumption of production, signaling dependence but also distance: “it’s not our plant.”
- Industry and analyst view
- Commentators see these strikes as part of a wider pattern: legacy carmakers under pressure from EV investments, Chinese competition, and shifting trade policies.
* Plants like Luton, and even some Italian and Polish facilities, are often discussed as “on the bubble” as Stellantis reworks its footprint, making any strike or shutdown feel like it could become permanent.

shutdowns
| Plant | Location | Type of action | Who struck? | Main output | Timeframe mentioned |
|---|---|---|---|---|---|
| Sterling Heights Assembly Plant (SHAP) | Michigan, USA | Direct plant strike | UAW workers at Stellantis plant | Ram 1500 pickup trucks | Stand Up Strike wave, late 2023 |
| Poissy | France | Production halted by supplier strike | MA France workers (supplier) | Compact cars/SUVs for Stellantis brands | Strike ongoing from mid‑April 2024 |
| Hordain | France | Production halted by supplier strike | MA France workers (supplier) | Vans and minibuses for Stellantis and Toyota | Same MA France strike period (April 2024) |
| Luton | United Kingdom | Production halted by supplier strike; later at risk of closure | MA France workers (supplier); broader restructuring pressures | Vans for Stellantis brands | Supplier strike in 2024, followed by later closure risk |
Why this topic is trending now
Even though each of these events occurred at slightly different times, they fit into a larger, very current storyline:
- Stellantis is restructuring globally, pushing toward EVs while trying to cut costs in Europe and North America.
- Unions are increasingly ready to use strike threats and actual walkouts to protect jobs and secure better deals.
- Supplier‑level strikes are becoming a sharper weapon, because a single plant like MA France can pull down three Stellantis factories at once.
For anyone following “what Stellantis plants are on strike,” the takeaway is that it’s no longer just about one factory walking out; it’s about a network of plants and suppliers where any weak link, or any angry workforce, can stop the whole system.
TL;DR : The main Stellantis sites specifically tied to strikes or strike‑driven shutdowns in recent coverage are SHAP in Michigan, plus the Poissy, Hordain, and Luton plants in Europe, all hit either by direct union walkouts or by a critical supplier strike at MA France.
