What's wrong?
The A, B, and C pillar covers on the 2019 S 450 are the trim panels that wrap the roof supports next to the windshield, the front doors, and the rear window. They hide the structure, but they also sit directly over the side curtain airbags. When a side airbag deploys in a crash, it pushes the cover out of the way and unfolds along the windows to protect occupants' heads.
On this vehicle, the pillar covers were reworked at the assembly plant after an incorrect bolt connection was found during production. The rework was not done to current production specifications on one side. With the covers fastened incorrectly, the side curtain airbag deployment can be affected, and the covers themselves can detach in a crash.
Owners can notice rattling noises from the pillar trim or a visible gap between a pillar cover and the pillar itself. Both are warning signs that the cover is not seated as designed.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific sedan is included in this recall.
What's the safety risk?
If a pillar cover detaches in a crash or a side curtain air bag fails to deploy as intended, occupants face a higher risk of injury. Watch for rattling from the pillar trim or a visible gap between the cover and the pillar, and schedule the repair soon if you notice either sign. Repair is free at any franchised Mercedes-Benz dealer.

What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the A, B, and C pillar covers and reinstalls any that were not properly secured at the factory. Parts and labor are free under the recall. Out-of-pocket repairs already paid are handled through the existing new-vehicle warranty, not through a separate reimbursement program, since the involved vehicle remains under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork for the pillar covers.

Frequently asked questions
What is recall 19V584?
Recall 19V584 covers 1 2019 Mercedes-Benz S 450 sedan whose A, B, and C pillar covers were improperly installed. The defect can prevent the side curtain air bags from deploying as intended and allow the covers to detach in a crash. A Mercedes-Benz dealer will inspect and reinstall the covers free of charge.
What should I do if my 2019 Mercedes-Benz S 450 is on this recall?
Check your VIN to confirm your specific vehicle is included in recall 19V584. If it is, contact a franchised Mercedes-Benz dealer to schedule the pillar-cover inspection and reinstallation. Reference recall number 19V584 when you call. The repair is free. You can also reach Mercedes-Benz customer service at 1-800-367-6372.
Is the recall repair free?
Yes. Federal recall law requires manufacturers to perform the recall repair at no cost. A franchised Mercedes-Benz dealer will inspect the A, B, and C pillar covers and reinstall them as needed at no charge, regardless of where the vehicle was originally purchased.
What is the safety risk?
If the side curtain air bag does not deploy as intended, or if a pillar cover detaches during a crash, the risk of injury to occupants increases. The defect does not affect normal driving, but the protection a side-impact crash relies on cannot be assumed until a dealer inspects and reinstalls the covers.
What if I bought my 2019 Mercedes-Benz S 450 used?
The free repair still applies. Federal recall law requires manufacturers to honor the recall regardless of ownership history. If Mercedes-Benz never mailed you a notice, check your VIN to confirm whether your vehicle is included, then reference recall number 19V584 when you contact a franchised Mercedes-Benz dealer.
