Recall 18V100 affects 180,462 2017-2018 Ram 1500, 2500, 3500, 4500, and 5500 trucks with shift interlock defects. Repair is free at any franchised Ram dealer.
Ram is recalling 180,462 2017-2018 Ram 1500, 2500, 3500, 4500, and 5500 vehicles with column shifters because the Brake Transmission Shift Interlock pin can stick open. That lets the transmission shift out of PARK without the brake pedal or key, raising rollaway risk; Ram dealers will complete the free repair.

What's wrong?
On 2017-2018 Ram 1500, 2500, 3500, 4500, and 5500 trucks with a column shifter, the Brake Transmission Shift Interlock is the small lock that keeps the transmission in PARK until the right conditions are met. When it works normally, the driver presses the brake pedal, the lock releases, and the shifter can move out of PARK.
In affected trucks, holding the brake pedal down for a long time while the engine is running and the transmission is in PARK keeps that interlock energized. Heat builds inside the gearshift bracket solenoid, the plastic housing swells, and the grease degrades. That leaves the locking pin stuck open, so the transmission can be shifted out of PARK without pressing the brake pedal or having the key in the ignition.
There is no warning sign before failure. The issue is not detectable to owners before the interlock pin sticks open.

What's the safety risk?
The shifter can move out of park without the brake pedal or a key in the ignition. That creates rollaway risk, which can lead to personal injury or a crash. There is no warning sign before failure, so keep the parking brake set and schedule the repair soon. Repair is free at any franchised Ram dealer.
What should I do?
- Check your VIN to confirm your 2017-2018 Ram 1500, 2500, 3500, 4500, or 5500 is included in this recall.
- Contact a franchised Ram dealer to schedule the free Body Control Module software update and BTSI test that fixes the shifter interlock problem.
- Bring the recall notice if Ram has mailed one. If not, reference recall number 18V100 when you call.
- Set the parking brake every time you park and confirm the transmission is in PARK until the repair is complete.
- Call Ram customer service at 1-800-853-1403 with questions and reference Ram recall U11.
What happens at the repair
At the dealer, a Ram technician updates the Body Control Module software. The technician then tests Brake Transmission Shift Interlock operation and replaces the solenoid if the test shows it is needed. Parts and labor are free under the recall. If you already paid to repair this condition before the recall notice, Ram's reimbursement process covers documented expenses. The owner letter explains how to send the original receipt or other proof of payment for confirmation of the expense.

Frequently asked questions
What is recall 18V100?
Recall 18V100 covers 180,462 2017-2018 Ram 1500, 2500, 3500, 4500, and 5500 vehicles with a column shifter. The Brake Transmission Shift Interlock pin can stick open after prolonged brake-pedal pressure in Park, allowing the transmission to shift out of Park without the brake pedal or key.
What should I do if my 2017-2018 Ram 1500, 2500, 3500, 4500, or 5500 is on this recall?
Check your VIN to confirm your specific Ram is included in recall 18V100. If it is, contact a franchised Ram dealer and reference recall U11. The dealer will update the Body Control Module software, test BTSI operation, and replace the solenoid if needed.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to complete the recall repair at no cost. A franchised Ram dealer will update the Body Control Module software, test the Brake Transmission Shift Interlock operation, and replace the solenoid if needed for free.
What is the safety risk?
The risk is unintended rollaway. If the transmission shifts out of Park without the brake pedal or key, the vehicle can move unexpectedly and increase the risk of personal injury or a crash. Until the repair is complete, confirm the truck is secure before exiting.
What if I bought this Ram used?
The free recall repair still applies. Recall eligibility follows the VIN, not the first owner. Check your VIN, then call a franchised Ram dealer with recall 18V100 or recall U11 so the service desk can confirm whether your truck still needs the repair.
