When does it fail?
Of the 12 electrical complaints filed for the 2013 Mercedes-Benz E-Class, here's the actual mileage breakdown — failures cluster heaviest at 25,000-50,000 mi.
Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
No new NHTSA electrical complaint has been filed on this vehicle in over 8 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: The 2013 E-Class has multiple electrical and control system issues reported, including unexpected stalling, transmission shifting to Park while driving (a known Mercedes issue with an issued bulletin), steering lock-ups, and accelerator problems. Even at low mileage these failures can occur; some dealerships cannot diagnose them and repairs are not always covered.
Owners of 2013 Mercedes-Benz E-Class vehicles report a cluster of electrical and control system failures, many occurring at relatively low mileage. Stalling with "Vehicle Inoperative" warnings appears early (29,000 miles), sometimes undiagnosed even after dealer visits. Throttle control problems include delayed response followed by sudden acceleration, with backup camera failures coinciding in one case.
Transmission issues stand out as particularly dangerous: multiple owners report the automatic shifting into Park without input while driving at low speeds—during traffic stops, intersections, and highway merging. Mercedes issued an Electronic Ignition Switch (EIS) bulletin acknowledging this problem. One owner experienced complete steering wheel lock-up tied to anti-theft system failure; the dealership confirmed other vehicles had the same defect.
Electrical system failures range from total loss of all functions at 900 miles to headlight malfunctions linked to Blind Spot Assist (BSA) malfunction. Owners report intermittent failures that don't always register on dealer diagnostics. Wiring harness defects appeared in multiple complaints—one with oil saturation affecting cam solenoid and O2 sensors, another with Pre-Safe warnings involving defective harness not covered under warranty. One severe case involved a stuck accelerator combined with brake ineffectiveness, resulting in a collision.

Failure modes owners describe
Unexpected stalling with 'Vehicle Inoperative' warning
Engine stalls while driving at low speed; warning message appears; vehicle can be restarted but failure recurs. Dealership unable to identify root cause but suggested software update may resolve it.
When: 29,000 miles
Symptoms owners cite: Vehicle inoperative warning message; Engine stalls while driving; Failure recurs after restart
Repairs/costs cited: Software update recommended but not yet performed; vehicle not repaired at time of complaint
Recalls/TSBs owners mention: Software update suggested as potential remedy
Unintended acceleration with delayed throttle response
Vehicle does not respond immediately when accelerator is pressed, then suddenly accelerates without driver input. Occurs sporadically in forward and reverse. Backup camera also became inoperative. Dealership unable to diagnose issue; problem does not register in vehicle computer.
When: 3,000 miles
Symptoms owners cite: Delayed throttle response followed by sudden acceleration; Sporadic unintended acceleration in reverse; Backup camera inoperative
Repairs/costs cited: Multiple dealer visits; no solution found; issue not reproducible via computer diagnostics
Steering wheel lock-up with anti-theft system failure
Steering column extension malfunctioned, then entire steering wheel locked up suddenly while driving. Anti-theft system became inoperative. Owner reports dealership confirmed multiple other vehicles had identical problem.
Symptoms owners cite: Steering column extension issue; Complete steering wheel lock-up; Anti-theft system malfunction
Repairs/costs cited: Required towing; high repair costs; 10-hour roadside delay
Transmission shifts to Park while driving
Vehicle automatically shifts into Park without driver input while slowing down or at low speeds, causing sudden stops. Occurs in heavy traffic and at traffic lights, creating dangerous conditions. Mercedes issued Electronic Ignition Switch (EIS) bulletin acknowledging the problem.
Symptoms owners cite: Unexpected shift to Park while driving; Sudden stop in traffic; Occurs when slowing down at low speeds
Codes mentioned: EIS (Electronic Ignition Switch)
Recalls/TSBs owners mention: Mercedes issued bulletin for Electronic Ignition Switch (EIS) regarding this failure
Blind Spot Assist (BSA) system malfunction affecting electrical systems

Symptoms owners cite: Headlight malfunction during driving; Dashboard messages flashing while driving; Intermittent electrical problems
Recalls/TSBs owners mention: Mercedes aware of issue; has not shared systemic failure data
Accelerator sticking with brake failure
Accelerator pedal became stuck and vehicle would not stop even when brakes were fully applied. Owner was unable to control vehicle deceleration, resulting in collision with another vehicle causing injury and total loss of car.
Symptoms owners cite: Stuck accelerator pedal; Brakes ineffective at stopping vehicle; Uncontrolled acceleration
Repairs/costs cited: Vehicle declared total loss with over 14,000 in damages
