Fuel Economy Overview

The 2016 Mercedes-Benz SLK300 achieves an EPA-estimated 27 MPG in combined city and highway driving, with 24 MPG in the city and 32 MPG on the highway. Powered by a 2L 4-cylinder turbocharged engine paired with a automatic 9-spd, this two seaters features Rear-Wheel Drive drive.

In terms of environmental impact, the 2016 SLK300 produces approximately 325 grams of CO2 per mile. This figure is measured under standardized EPA test conditions and represents tailpipe emissions only. For context, the average new vehicle sold in the United States produces approximately 400 grams of CO2 per mile, meaning this SLK300 performs better than the national average in this regard.

The estimated annual fuel cost for this vehicle is $2,550, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would save $2,000 over a 5-year period. This calculation accounts for differences in fuel consumption efficiency and provides a practical measure of long-term ownership costs attributable to fuel economy.

Campaign #19V787000·2019-12-23
moderate
Component: COMMUNICATION

Mercedes-Benz USA, LLC. (MBUSA) is recalling certain 2013-2017 vehicles due to a software fault that may cause the date and time for the emergency call system (eCall) to differ from the actual date and time, potentially relaying an inaccurate vehicle location. For a full list of the affected models visit: https://static.nhtsa.gov/odi/rcl/2019/RMISC-19V787-4620.pdf

Consequence & Remedy

critical
Component: SUSPENSION:REAR

Mercedes-Benz USA, LLC (MBUSA) is recalling certain model year 2016 SLK300 vehicles manufactured January 19, 2016 to April 19, 2016. In the affected vehicles, improperly manufactured lock nuts may have been used on the rear wheel tie rod connection, and as a result, the rear wheel alignment may change and the rear axle may steer independently.

Consequence & Remedy

Consequence: A change of the rear wheel alignment and independent steering of the rear axle may increase the risk of a crash.

Remedy: MBUSA will notify owners, and dealers will replace the lock nuts on the rear tie rods, free of charge. The recall began on June 24, 2016. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2016050008.

Campaign #16V211000·2016-05-09
moderate
Component: ELECTRICAL SYSTEM:WIRING

Mercedes-Benz USA, LLC (MBUSA) is recalling certain model year 2016 SLK300 vehicles manufactured June 2, 2015 to July 14, 2015 and equipped with a nine-speed automatic transmission. The backup power supply for the ignition switch in the affected vehicles may not have been properly connected. As a result, if the vehicle is being driven and there is a loss of power from the main vehicle battery, the transmission cannot be shifted to "Park" nor can the electric parking brake be applied.

Consequence & Remedy

Consequence: In this situation, without the backup power supply, the only way to keep the vehicle from moving is to press the brake pedal. As soon as the driver attempts to exit the vehicle, the vehicle may roll, increasing the risk of injury.

Remedy: MBUSA will notify owners, and dealers will correct the ignition switch wiring and perform a software update, free of charge. The recall began on May 9, 2016. Owners may contact MBUSA customer service at 1-800-367-6372.
