Other CL - EW M157

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Dear Mercedes-Benz Owner: In our continuing efforts to ensure the proper performance of Mercedes-Benz products and to enhance the satisfaction of our customers, Mercedes-Benz USA is extending the warranty coverage on the pressure transducer, vacuum pump, and vacuum lines in your vehicle from the original New Vehicle Limited Warranty of 4 years / 50,000 miles to 15 years/ 150,000 miles (whichever occurs first). This applies to the vehicle regardless of ownership. On certain Model Year 2015 - 2019 CLS, E-Class, G-Class, GLE, GL, GLS, ML, SL and S-Class vehicles with the "M 157" 8-cylinder engine, over time, the pressure transducer and vacuum pump might not continue to work as intended and could result in illumination of the check engine Malfunction Indicator Lamp ('MIL') and the activation of limp-home mode. Any repairs under this warranty extension must be performed by an authorized Mercedes-Benz dealership. •If your preferred authorized Mercedes-Benz dealership performs diagnosis and confirms that your vehicle meets the criteria for this extended warranty, the repair will be covered at no cost to you. •This extended warranty does not apply to any other components or conditions beyond the ones described under this extended warranty, and standard warranty terms apply, including the exclusions with respect to extra expenses, as identified in the Service and Warranty Information booklet.
