Ram is recalling 23,853 2019-2021 Promaster City vehicles under recall 21V728 because a failed turn signal can leave the flashing rate unchanged instead of warning the driver. When the signal is out, other drivers do not get a clear signal of the driver's intent, increasing crash risk; Ram dealers will repair the issue free of charge.

What's wrong?
The Body Control Module on the 2019-2021 Ram Promaster City is the electronic controller that manages body functions, including exterior lighting checks. The Instrument Panel Cluster is the dashboard display in front of the driver, and it uses information from that module to show the turn signal indicator and its flashing rhythm.
On affected vehicles, the Body Control Module has a diagnostic software problem. When a turn signal bulb is not working, the module does not tell the Instrument Panel Cluster to change the indicator flash rate. That faster flash is the driver's normal clue that a turn signal bulb has failed, so the vehicle can keep showing a normal rhythm on the dashboard while the outside lamp is out.
There is no warning sign before failure. If a turn signal bulb stops working, the dashboard indicator stays at the normal flashing rate instead of alerting the driver.
Who's affected?
The body-controller turn-signal module is the common part across the 2019, 2020, and 2021 Promaster City.
| 2019 Ram Promaster City | Turn signal |
|---|---|
| 2020 Ram Promaster City | Turn signal |

| Units affected | 23,853 |

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific van is included.
What's the safety risk?
A driver can be unaware that the turn signals are not showing an intended turn or lane change. Other drivers then lose a key warning, which increases crash risk. There is no warning sign listed for owners, so schedule the software update soon. Repair is free at any franchised Ram dealer.
What should I do?
- Check your VIN to confirm your 2019-2021 Ram Promaster City is included in this recall.
- Contact a franchised Ram dealer to schedule the free BCM software update that fixes the turn-signal failure warning behavior.
- Bring the recall notice if Ram mailed one. If not, reference recall number 21V728 when you call.
- Use extra caution until the repair. Check turn signal operation before driving and signal lane changes early.
What happens at the repair
At the dealer, a Ram technician updates the Body Controller Module software. This BCM update corrects the turn signal failure warning behavior covered by the recall. The software update and labor are free under the recall. If you already paid to repair this condition before the owner letter, FCA US's reimbursement process asks customers to send the original receipt or other adequate proof of payment to the company for expense confirmation.

Frequently asked questions
What is recall 21V728?
Recall 21V728 covers 23,853 2019-2021 Ram Promaster City vehicles with turn signal software that fails Federal Motor Vehicle Safety Standard number 108. If a turn signal light fails, the flashing rate can fail to change, leaving the driver unaware that other drivers are not seeing the signal.
What should I do if my 2019-2021 Ram Promaster City is on this recall?
Check your VIN to confirm your specific vehicle is included in recall 21V728. If it is, contact a franchised Ram dealer to schedule the Body Controller Module software update. Reference recall number 21V728 or FCA recall Y71 when you call.
Is the recall repair free?

What is the safety risk in recall 21V728?
The risk is that other drivers do not see your turn signal when a turn signal light has failed. The driver lacks the expected faster flashing warning, so a lane change or turn signal error can increase the risk of a crash.
