Stellantis has initiated safety recall campaigns to address separate software and hardware vulnerabilities affecting certain late-model pickup trucks. The primary action involves a digital display malfunction where a software error can cause the 12-inch instrument panel cluster to go blank or fail to initialize at vehicle startup. According to safety filings submitted to the National Highway Traffic Safety Administration, an inoperative display screen violates federal motor vehicle safety standards because it obscures critical information, such as the speedometer, gear selection indicator, and warning lights.

A secondary concern involves a hardware vulnerability in the trailer tow control module. This issue can cause an unexpected loss of trailer brake communication and trailer lighting illumination, which presents a significant hazard when hauling heavy loads. To resolve these safety vulnerabilities, our certified service department performs specialized diagnostic scans and system updates. If your truck is affected, our technicians will inspect and update the instrument panel software or replace the instrument panel cluster as necessary.

These safety campaigns are tracked under manufacturer recall codes B4C and B8C. Owners can verify if their vehicle is included by contacting our service team directly at (833) 979-0199. For drivers who reside near Thurmont, scheduling a diagnostic check is an essential step in maintaining the utility and safety of your truck. You can consult with our staff or ask a service technician about the specific software patch versions required for your vehicle.

Identifying Affected 2025 and 2026 Ram 1500 Models

The scope of the instrument cluster recall focuses specifically on vehicles configured with the premium 12-inch instrument panel cluster. While the software bug is serious, manufacturer records indicate that the defect is estimated to affect approximately 1% of the total recalled population of 72,509 vehicles. This population includes a mix of light-duty and heavy-duty trucks built for the 2025 and 2026 model years. Standard analog gauge clusters or smaller digital driver information displays are not included in this campaign.

The companion trailer brake module recall affects a broader group of trucks equipped with factory trailer-tow packages. When evaluating pre-owned vehicles, our service team cross-references the vehicle identification number against open campaigns. If you are researching a pre-owned truck on our used vehicle specials page, we ensure that all safety recalls are fully resolved before any vehicle is cleared for service or delivery.

Our service department utilizes factory databases to pinpoint affected vehicles by build date and configuration. This level of precision is also applied when we service other advanced vehicles, such as those who bring in a Jeep Grand Cherokee for electrical diagnostics, or performance enthusiasts keeping their systems updated in a Dodge Charger. If your truck was built during the suspect manufacturing windows, our service advisors can run your VIN to verify if the software flash is required.

​

Recognizing Warning Signs of Display or Trailer Brake Module Failures

Drivers should remain alert to the physical symptoms of these electrical and communication faults. The instrument cluster failure typically manifests at vehicle startup, where the screen remains completely dark, or during active driving, when the screen may suddenly freeze, flicker, or shut down entirely. This cuts off access to critical safety features, including the electronic stability control malfunction indicator, speedometer readings, and transmission gear displays.

For truck owners who haul agricultural equipment or trailers through Chambersburg, a failing trailer tow module presents distinct, noticeable warning signs:

  • The central infotainment screen displays a "Trailer Brake Disconnected" message.
  • Trailer brake controller output sliders do not register voltage when squeezed manually.
  • External trailer brake lights and turn signals flicker, dim, or fail to illuminate entirely.
  • The physical trailer tow module, located under the dashboard, operates at an elevated temperature.

If you experience these symptoms while traveling, pulling over safely is highly recommended. Our technicians assist drivers from all over, including those who visit our dealership near Harrisburg for advanced electrical repairs. We apply the same diagnostic rigor to all family and utility vehicles, whether we are troubleshooting a digital cockpit on a Jeep Grand Cherokee L or checking the wiring harness on a Chrysler Voyager.

​

What to Expect During Your Free Software and Module Recall Repairs

Repairing these recall issues is completely free of charge to the vehicle owner. For the instrument cluster display issue, our factory-trained technicians connect your truck to our secure diagnostic network to perform a complete flash update of the instrument panel cluster software. This update resolves the boot-up sequence error and prevents the display from freezing or going dark. If the cluster is found to have a physical hardware defect during our diagnostic check, we will replace the physical cluster unit.

The trailer brake repair involves replacing the physical trailer tow module with a redesigned, robust component. Our department keeps a steady supply of genuine Mopar components in stock. If you prefer to order specific components or accessories for your vehicle, you can easily order parts through our online portal.

Most software updates and module replacements can be completed in about one hour of active shop time. However, we recommend scheduling an appointment in advance so we can reserve a dedicated diagnostic bay and have the necessary software patches or hardware modules ready for your vehicle. This organized approach keeps our service bays running smoothly, whether we are performing a software update on a truck, installing trail accessories on a Jeep Wrangler, or servicing the suspension on a Jeep Gladiator.

Safety Guidelines and Defensive Driving Before Completing Recall Service

If your truck's instrument cluster goes blank before you can bring it in for service, you must take immediate precautions to ensure safe operation. Without a functional digital display, you will lose your speedometer and gear indicator. In this situation, you should use the backup physical gear cues, such as the illuminated gear letters next to the rotary shifter dial, to confirm your transmission status. Always engage the electronic parking brake when parking to prevent any rollaway risk.

When towing, always perform a physical pre-trip inspection of your trailer. Have a partner stand behind the trailer to verify that the brake lights, tail lamps, and turn signals function correctly when you press the brake pedal in the cab. If you notice any flickering or connection loss, do not tow the trailer until the module is inspected.

These safety principles apply to every vehicle on the road. Whether you are driving a highly capable Jeep Wrangler Unlimited on rugged terrain, commuting in a Jeep Cherokee, or taking a family trip in a Chrysler Pacifica, verifying your safety indicators and trailer connections is vital to protecting your passengers and other drivers.

​

Understanding Warranty Protection and Recurrent Repair Protections

All safety recall repairs are fully covered under the manufacturer's warranty guidelines and are performed at no cost to you, regardless of your vehicle's mileage or original purchase date. These campaigns are designed to address specific, documented manufacturing defects to ensure your truck meets all federal safety regulations.

For vehicles that experience repeated, unresolved electrical or mechanical issues that cannot be repaired after a reasonable number of attempts, state consumer protection laws may provide additional coverage. In many areas, if a vehicle spends more than 30 days out of service for warranty repairs, or requires multiple attempts to fix a major safety defect, the owner may be eligible for a vehicle buyback or replacement.

Keeping detailed copies of every service repair order is essential for protecting your ownership rights. Our service department provides clear, transparent documentation for every visit. This professional care extends to all premium vehicles we service, from luxury SUVs like the Jeep Grand Wagoneer to performance models like the Dodge Durango.

Common Questions About the 2026 Ram 1500 Software Updates

We understand that vehicle recalls can raise questions about scheduling, safety, and repair procedures. Below are answers to the questions our service advisors hear most frequently from truck owners.

Q: How do I verify if my specific truck is included in the instrument cluster recall?

You can check your vehicle's recall status by locating your 17-digit Vehicle Identification Number, which is printed on the driver's side dashboard or your vehicle registration card. Call our service department, and we will run your VIN through the factory database to check for any open campaigns.

Q: Can both the instrument cluster update and the trailer brake module repair be completed in a single visit?

Yes. Our service department can perform the digital instrument cluster software flash and replace the trailer tow control module during the same appointment. Combining these services helps minimize your downtime and gets your truck back on the road quickly.

Q: Is there any charge for the diagnostic scan or the replacement parts?

No. All recall-related diagnostics, software updates, and replacement modules are performed free of charge. The manufacturer covers all parts and labor costs associated with these safety campaigns.

Q: What should I do if my display screen goes dark while I am driving?

If your display screen fails while driving, maintain a safe distance from other vehicles, use your physical gear shift indicators to monitor your transmission, and pull over safely when possible. Contact our service team to schedule an immediate diagnostic check and software update.

Q: How long will my truck need to be in the shop for these repairs?

The active repair time for the software update and module replacement is usually about one hour. However, we recommend planning for your vehicle to be at our facility for a half-day to allow for check-in, diagnostic verification, and quality testing.
