Ford has announced a major recall tied to a trailer controller issue affecting more than 4.3 million vehicles. According to NHTSA recall documents, the problem involves the Integrated Trailer Module, also called the ITRM, which can lose communication with the vehicle. When that happens, trailer stop lights and turn signals may stop working, and in some vehicles, trailer brake function can be affected too.
For anyone who tows regularly, this is not something to ignore. Trailer lighting and braking are a huge part of safe towing, and a problem like this can reduce visibility and control while you are on the road. NHTSA says those failures can increase the risk of a crash.
What is the Ford recall about?
The recall centers around a software issue in Ford’s Integrated Trailer Module. NHTSA says the module may lose communication with the vehicle during startup, which can lead to the loss of trailer stop lamps and turn signals, along with loss of trailer brake function on certain versions of the module.
In simple terms, your truck or SUV may think everything is fine until the trailer functions you rely on are not working like they should.
Why this matters when towing
When you are towing, your trailer lights help other drivers see when you are stopping or turning. Your trailer brakes also play a major role in helping keep the trailer controlled and stable behind your tow vehicle.
If those systems are not working correctly, it can create a dangerous situation fast. Even experienced towers know that small towing issues can turn into major problems once you are out on the highway, in traffic, or going downhill.
This recall is a good reminder that towing safety is not just about the trailer itself. Your tow vehicle’s systems matter just as much.
What drivers may notice
Ford owners affected by this issue may see a warning message on the instrument panel that says “Trailer brake module fault.” NHTSA’s recall report also says some drivers may notice the turn signal indicator flashing quickly, and in some cases a “Blind Spot Assist System fault” message may appear as well.
If you see any of those warnings while towing, it is worth taking seriously.
Which Ford vehicles are affected?
Reports say the recall affects certain Ford vehicles from model years 2021 through 2026, including models such as the F-150, F-250 Super Duty, E-Transit, Expedition, Maverick, Ranger, and Lincoln Navigator.
Because recall eligibility depends on the exact vehicle, owners should still check their VIN directly through Ford or NHTSA instead of assuming they are or are not included. NHTSA’s recall site allows owners to search by VIN, and manufacturers are required to notify registered owners by mail.
What is the fix?
NHTSA’s recall report says the remedy is a software update for the Integrated Trailer Module. Ford expects to provide that update over the air for many affected vehicles starting in May 2026, and owners can also go to a Ford or Lincoln dealer for the repair at no charge.
What trailer owners should do now
If you drive a Ford and tow trailers, now is a good time to:
- Check your VIN for open recalls
- Pay attention to any trailer brake or trailer lighting warning messages
- Test your trailer lights and brake functions before towing
- Schedule the recall repair if your vehicle is affected
Even if your setup seems fine, a quick check before every trip is always worth it.
Final thoughts
Safe towing depends on both your trailer and tow vehicle working together. Even a properly loaded trailer can become unsafe if trailer control systems are not working. If you tow with a Ford, check whether your vehicle is included in the recall.
A quick recall check can make a big difference before your next trip.
