Stellantis recalls 11,980 Jeep Grand Wagoneer and Wagoneer L SUVs over software that can disable stability con

Here’s the short version: if you own a brand-new 2026 Jeep Grand Wagoneer or Wagoneer L, the software that runs your brake system might have shipped with a bug — and that bug can shut off your electronic stability control without asking you first. Stellantis is recalling 11,980 of these big SUVs to fix it.

That’s not a cosmetic problem. Stability control is one of the systems doing quiet work in the background every time you drive, and losing it changes how the truck behaves when things get squirrelly.

What actually fails here

The trouble is in the brake system control module. That’s the computer that manages your braking hardware, and on these vehicles it also handles electronic stability control — ESC for short.

According to the filing, some of these SUVs were built with faulty software loaded into that module. When the software misbehaves, it can disable ESC entirely.

Here’s why that matters mechanically. Stability control watches your wheel speeds, your steering angle, and how the vehicle is actually rotating versus how you’re telling it to go. When it senses the truck starting to slide — understeer plowing toward the outside of a curve, or oversteer where the back end wants to come around — it brakes individual wheels on its own to pull you back into line. It works fast and it works without you doing anything.

Take that away and the vehicle drives like an older truck with no electronic safety net. On dry pavement in a straight line, you’d never know the difference. But on a wet on-ramp, on gravel, or in a hard evasive maneuver, ESC is exactly the system that keeps a tall, heavy SUV from getting away from you. A Grand Wagoneer is a big vehicle with a high center of gravity. That’s the last kind of truck you want losing stability control in a panic move.

The real catch is that you may not get a warning you’d notice in time. If the software disables ESC, you might not find out until the moment you actually needed it.

What the filing says

Stellantis is recalling 11,980 vehicles across two models: the 2026 Jeep Grand Wagoneer and the 2026 Jeep Wagoneer L. The cause is that faulty brake system control module software. The stated safety risk is that ESC can be disabled, which raises the risk of a crash.

The fix is a software update, and dealers will handle it free of charge. No parts to replace here — this is a reflash of the control module, correcting the code that’s causing the problem.

For context, this is the second major Jeep recall in about a month. The prior one, in June, covered more than a million Wrangler and Gladiator vehicles over a power steering wiring fire risk. That’s a completely separate issue on completely different vehicles, but it tells you the brand has had a busy few weeks in the recall department.

What this means if you own one

If you’ve got a 2026 Grand Wagoneer or Wagoneer L in your driveway, here’s how I’d handle it.

1. Run your VIN. Go to the NHTSA recall lookup and enter your vehicle identification number. That’s the only way to confirm whether your specific truck is in the affected batch of 11,980. The VIN sits at the base of the windshield on the driver’s side and on your registration.

2. Don’t ignore a stability-control warning light. If your ESC light comes on and stays on, or you get a message saying stability control is off, treat that as real. Get the truck to a dealer. Don’t assume it’s a glitch you can drive through.

3. Schedule the update when you’re notified. This is a software flash, so it’s a quick fix by recall standards. There are no parts to wait on. Call your dealer, book the appointment, and get it loaded.

4. The repair is free — full stop. A recall remedy for a safety defect doesn’t cost you anything. Nobody at the counter should be quoting you a diagnostic fee or a labor charge for this. If they try, that’s your cue to push back.

5. Document everything. Keep your paperwork from the dealer showing the update was performed and the date. If you ever have a stability-related incident, you want proof of when the fix went on the truck.

My take

This one’s serious in principle and easy in practice. Losing electronic stability control on a heavy SUV is a genuine safety concern — that’s not me being dramatic, that’s what the system is there to prevent. But the remedy is about as painless as recalls get. A software update, no cost, no parts backorder.

So don’t file this one under “I’ll get to it.” Run your VIN, get the flash loaded, and keep the receipt. It’s a small ask for a system you count on without ever thinking about it.
