2022 Mercedes-Benz E-Class
Vehicle Specs & Maintenance Data
The 2022 Mercedes-Benz E-Class maintenance specs on this page cover the key fluids, torque values, and wear items you need for routine service. Use these numbers as a quick reference when performing oil changes, tire rotations, brake jobs, and other scheduled maintenance on your Mercedes-Benz E-Class.
For oil changes, the 2022 Mercedes-Benz E-Class takes 0W-40 Full Synthetic motor oil with a capacity of 5.5 quarts. Brake fluid type is DOT 4, the recommended coolant is MB 325.0 (Blue, silicate-free), and transmission fluid is MB 236.14. Always use the manufacturer-recommended fluids to maintain warranty coverage and engine longevity.
When mounting wheels on the Mercedes-Benz E-Class, torque the lug nuts to 96 ft-lbs using a calibrated torque wrench. Over- or under-torquing can lead to warped brake rotors or loose wheels. Re-torque after 50 to 100 miles on newly installed wheels.
Owners of the 2022 Mercedes-Benz E-Class have reported 5 common issues including "9G-TRONIC Transmission Rough Shifting and Delayed Engagement", "M264 Engine Coolant Leak from Thermostat Housing" and "AIRMATIC Suspension Air Spring Leak".

9G-TRONIC Transmission Rough Shifting and Delayed Engagement
The 9G-TRONIC (9-speed 725.0) automatic transmission in the 2022 E-Class can exhibit rough or jerky shifts, particularly during the 1-2 and 2-3 upshifts when the transmission is cold. Some owners report a noticeable delay of 2-3 seconds when shifting from Park to Drive or Reverse, and occasional harsh downshifts during highway passing maneuvers.
Dealer performs a transmission adaptation reset using the XENTRY diagnostic system and updates the transmission control unit (TCU) software to the latest calibration. A transmission fluid and filter change using MB 236.17 fluid may also be performed. Reference TSB LI27.00-P-065229 for 9G-TRONIC shift quality diagnosis.
Est. Cost: $0 (software update) - $1,200 (fluid change and adaptation)M264 Engine Coolant Leak from Thermostat Housing
The 2.0L M264 turbocharged engine used in the E 350 develops coolant leaks from the thermostat housing gasket and the plastic coolant crossover pipe. Owners notice sweet-smelling coolant odor, low coolant warnings, and visible coolant pooling under the vehicle. The plastic housing becomes brittle over time due to heat cycling.
Dealer replaces the thermostat housing, gasket, and coolant crossover pipe. An updated thermostat housing with improved material is available under revised part numbers. The cooling system must be properly bled after repair. Reference TSB LI20.20-P-063447 for coolant leak diagnosis.
Est. Cost: $500 - $1,500AIRMATIC Suspension Air Spring Leak
E-Class models equipped with AIRMATIC air suspension are susceptible to air spring leaks, particularly at the rubber bellows where they crimp to the piston. The vehicle sags on one corner overnight or within a few hours of parking. A 'Vehicle Too Low' warning message illuminates, and the air compressor runs excessively trying to maintain ride height, eventually burning out.
Dealer replaces the leaking air spring assembly. Both air springs on the same axle should be replaced simultaneously. The air suspension compressor should be tested for damage from overwork. Reference Mercedes-Benz TSB LI32.30-P-068471 for AIRMATIC system diagnosis.
Est. Cost: $1,200 - $3,000 per air springElectronic Parking Brake Malfunction
The electronic parking brake can fail to engage or release, displaying a 'Parking Brake Malfunction' warning on the dashboard. Owners report the parking brake applying itself unexpectedly while driving at low speeds or failing to hold the vehicle on inclines. The issue is traced to the electric parking brake actuator motor or its wiring harness corroding.
Dealer replaces the electronic parking brake actuator on the affected caliper(s). The brake control module software should be updated and the system recalibrated. Reference TSB LI42.60-P-065891 for electronic parking brake diagnosis.
Est. Cost: $500 - $1,400Driver Assistance Systems (Distronic) False Alerts
The Distronic adaptive cruise control and active steering assist systems generate false collision warnings and phantom braking events, particularly in curves, highway underpasses, and when passing reflective road signs. The forward-facing radar and camera sensors can be triggered by metal guardrails and bridge overpasses. These sudden braking events can startle the driver and create rear-end collision risk.
Dealer recalibrates the front radar sensor and stereo camera using the XENTRY ADAS calibration system. Software updates to the driver assistance control module improve object detection algorithms. Reference Mercedes-Benz TSB LI69.60-P-070192 for Distronic false alert diagnosis.
Est. Cost: $0 (software update) - $800 (sensor recalibration)
