2018 Mercedes-Maybach S-Class Recall 18V407: Prefuse Box

Recall 18V407 affects 1,701 2018 Mercedes-Maybach S-Class vehicles for unsecured pre-fuse-box power bars. Repair is free at any franchised Mercedes-Maybach dealer.

Mercedes-Maybach is recalling 1,701 2018 S 560 4MATIC, S 650, S 450, and S560 vehicles because electrical power bars inside the trunk pre-fuse box were not secured properly. Higher resistance can raise the risk of fire, and intermittent contact can impair engine operation, seat belt functions, or the instrument cluster; Mercedes-Maybach dealers will complete the repair free of charge.

What's wrong?

The pre-fuse box in the trunk of these 2018 Mercedes-Maybach S 560 4MATIC, S 650, S 450, and S560 vehicles is part of the main electrical protection system. It routes battery power through heavy electrical bars and fuses before that power reaches vehicle systems. The securing nuts keep those power bars clamped in place so the connection stays tight under normal driving vibration.

In affected vehicles, a supplier production error left two securing nuts off the power bars inside the pre-fuse box. Without those nuts, the power bars are not held as designed. The connection can loosen or lose contact, which interferes with electrical power delivery and can affect vehicle functions, including engine starting.

Owners should watch for warning messages in the instrument cluster. Those messages are the warning sign Mercedes-Maybach identified when vehicle functions are lost or impaired.

A matching 2018 Mercedes-Maybach model does not guarantee inclusion. Check your VIN to confirm whether your specific sedan is included.

What's the safety risk?

Improperly secured power bars raise electrical resistance and increase the risk of a fire. Intermittent contact can also impair engine operation, seat belt functions, and the instrument cluster, increasing the risk of a crash and injuries. Warning messages in the instrument cluster alert the driver when these functions are impaired. Repair is free at any franchised Mercedes-Maybach dealer.

What should I do?

  1. Check your VIN to confirm your 2018 Mercedes-Maybach S 560 4MATIC, S 650, S 450, or S560 is included in this recall.
  2. Contact your nearest franchised Mercedes-Maybach dealer to schedule the free pre-fuse-box inspection and replacement that secures the trunk power bars.
  3. Bring the recall notice if Mercedes-Maybach mailed one. If not, reference recall number 18V407 when you call.
  4. Drive only as needed until the repair is complete, and stop in a safe place if electrical functions, engine operation, seat belt functions, or the instrument cluster act abnormally.
  5. Call Mercedes-Maybach customer service at 1-800-367-6372 with questions.

What happens at the repair

At the dealer, a Mercedes-Maybach technician inspects the pre-fuse box in the trunk and replaces it if the electrical power bars or related housing need replacement. The recall repair is free, with parts and labor covered. Mercedes-Maybach uses the manufacturer's standard reimbursement plan for this campaign, so owners who already paid for a related pre-fuse box repair can ask customer service or the dealer service desk how to submit documented expenses.
