What the defect is

Mercedes-Benz is recalling certain model year 2013 SL-Class vehicles manufactured from December 19, 2011, through May 31, 2012 originally equipped with R1234yf refrigerant. Daimler AG (DAG), the parent company of Mercedes-Benz, conducted product testing of a vehicle, not sold in the US, but equipped with the same refrigerant. According to Mercedes-Benz, the testing was designed to replicate worst-case conditions expected in a severe frontal crash that would cause a rupture of the air conditioner refrigerant line. A rupture of a refrigerant line will result in a gaseous mixture of refrigerant being released into the engine compartment.

What could happen

The testing conducted by DAG determined that the escaping R1234yf refrigerant may ignite under specific conditions. The resulting fire could spread to additional combustible materials.

What gets fixed

Mercedes-Benz will notify owners, and dealers will replace the R1234yf refrigerant with R134a along with new refrigerant lines (hoses) designed specifically for R134a. The remedy will be provided free of charge. The safety recall began on November 8, 2012.

Your rights

A safety recall repair is free. Under US federal law the manufacturer must fix a safety defect at no cost to you — no charge for parts, labor or diagnosis — whether or not you are the original owner. A dealer cannot charge you for recall work, and cannot require you to have bought the vehicle from them.

That entitlement is not unlimited. It applies where the vehicle was first sold less than 15 years before the recall was announced — 5 years for tires. Past that a manufacturer may still do the repair free of charge, and many do, but they are no longer obliged to. This recall was reported on 1 October 2012.

To arrange the repair, contact any franchised dealer for the brand. If a dealer refuses the work or tries to charge for it, you can report that to NHTSA at nhtsa.gov/recalls or on 1-888-327-4236.

Everything on this page — the models listed, the build dates and the repair figures — comes from the manufacturer's filing to NHTSA and describes the vehicle line as a whole, not any individual car. Only the manufacturer can confirm whether a specific vehicle is affected, and whether its recall work has already been carried out. Check yours by VIN and read the official notice at nhtsa.gov/recalls.

Additional notes

Owners may also contact the National Highway Traffic Safety Administration's Vehicle Safety Hotline at 1-888-327-4236 (TTY: 1-800-424-9153); or go to http://www.safercar.gov.

Check your own vehicle

This page describes the recall, not any one car. To see which recalls cover a specific vehicle, search by make, model and year.

A VIN lookup here identifies your vehicle and shows recalls issued for that make, model and year. It cannot tell you what is still open on your individual car - only the manufacturer knows that. Search by VIN instead, or check your VIN at nhtsa.gov for whether a recall is still open on your individual car.
