Recall 15V505 affects 209 2015-2016 Mercedes-Benz E400, E350, E63, CLS400, CLS550, and CLS63 vehicles for a loose engine-bay rubber seal. Free dealer repair.
Mercedes-Benz is recalling 209 2015-2016 E400, CLS550, CLS400, E63, CLS63, and E350 vehicles because supplier rework damaged the steel cable that secures a rubber seal at the bulkhead. If that seal drops into the engine compartment, it can contact engine or exhaust parts and raise the risk of a fire; Mercedes-Benz dealers will secure it free of charge.

What's wrong?
In recall 15V505, the problem is the rubber seal at the secondary bulkhead on certain 2015-2016 Mercedes-Benz E400, CLS550, CLS400, E63, CLS63, and E350 vehicles. The secondary bulkhead sits near the rear of the engine compartment. The seal helps close off that area, and an integral steel cable helps hold the rubber seal firmly in place.
On affected vehicles, supplier rework damaged that steel cable. With the cable weakened, the seal does not have the holding force Mercedes-Benz designed into the part. When the hood is opened, the rubber seal can stick to the hood; when the hood is closed, the seal can drop into the engine bay.
The warning sign is a seal that looks loose, pulled out of position, or dropped into the secondary bulkhead area. If you see that, tell the Mercedes-Benz dealer the bulkhead rubber seal is loose or has fallen into the engine compartment.
Who's affected?
Spans six Mercedes-Benz E400, CLS550, CLS400, E63, CLS63, and E350 cars across the 2015 and 2016 model years, all tied to the engine component.

What's the safety risk?
A loose rubber seal can fall into the engine compartment near the secondary bulkhead. If it contacts engine or exhaust parts, fire risk increases. Confirm whether your VIN is included and schedule the recall repair soon. Repair is free at any franchised Mercedes-Benz dealer.
What should I do?
- Check your VIN to confirm your 2015-2016 Mercedes-Benz E400, CLS550, CLS400, E63, CLS63, or E350 is included in this recall.
- Contact a franchised Mercedes-Benz dealer to schedule the free rubber-seal replacement that keeps the engine-compartment seal secured away from hot engine and exhaust parts.
- Bring the recall notice if Mercedes-Benz mailed one. If not, reference recall number 15V505 when you call.
- Call Mercedes-Benz customer service at 1-201-573-5339 with questions about scheduling or dealer availability.
- Avoid unnecessary hood openings until the repair is complete. After any hood opening, make sure the rubber seal is not loose in the engine bay before driving.
What happens at the repair
At the dealer, a Mercedes-Benz technician replaces the rubber seal in the engine compartment so it stays secured to the bulkhead when the hood is opened and closed. The recall repair is available now, and parts and labor are free. Mercedes-Benz uses the manufacturer's standard reimbursement plan for owners who already paid for this related repair before the recall notice. Bring repair invoices, receipts, and proof of payment to the service desk so the dealer can explain how to submit the claim.
