Owners have filed 25 powertrain complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Among the 14 model years of Mercedes-Benz E-Class in our records for powertrain problems, this one ranks #2 by owner-complaint volume.
The failure pattern owners describe
Owners of 2007 Mercedes E-Class vehicles consistently report transmission failures characterized by loss of gear engagement, stuck gears, and sudden power loss—often without warning lights. The 7-speed automatic transmission is the primary culprit. Multiple owners describe vehicles becoming trapped in a single gear (typically 1st or 3rd), unable to accelerate past 15–20 mph or reach highway speeds, sometimes on busy freeways. One owner's transmission failed three times in ten months with unpredictable recurrence even after software updates and dealer repairs. Transmission disengagement into neutral while driving has also been documented, forcing owners to restart engines mid-journey. Harsh jerking and violent downshifting have caused loss of vehicle control on wet pavement.
Separately, balance shaft wear is a documented defect; one owner's engine gear was reported "chewed up," and a class action suit was filed. Repair costs ranged $4,000–$10,000 depending on severity. Transfer case defects causing vibration and shuddering were identified in a 2009 manufacturer bulletin for this model year, yet one owner was charged $3,200 out-of-pocket despite partial manufacturer coverage. Engine shutdowns while driving and oil-soaked wiring harnesses have also been reported. Dealership responses include software updates, transmission fluid additions, and partial repairs; however, no comprehensive solution has been documented, and owners frequently find that restarts provide only temporary relief.

Recalls/TSBs owners mention: Class action suit; manufacturer agreed to pay portion of repairs for affected VINs; some owners received 25% coverage only
Transmission Shift Failure and Gear Engagement Loss
Transmission fails to shift gears properly or engage, leaving vehicle stuck in a single gear or neutral. Multiple owners reported sudden loss of drive capability on highways and city roads, sometimes without warning indicators. Restart of engine temporarily resolves issue on some occasions; pattern suggests electronic/hydraulic control malfunction.
When: 600–113,000 miles; complaints span 2008–2016
Symptoms owners cite: Transmission will not shift out of gear (stays in 1st, 2nd, or high gear); Vehicle cannot accelerate past 20 mph or cannot reach highway speeds; No power on acceleration from stop; Erratic shifting; Inability to engage reverse; Loud winding noise from transmission; No warning light or indicator when failure occurs
Repairs/costs cited: $2,300–$5,800 for transmission service, reprogramming, or replacement; one owner reported metal shavings in transmission pan at 60,000 miles after prior service at 39,000 miles
Recalls/TSBs owners mention: Dealerships performed PCM reprogramming and transmission fluid additions; software updates applied; one service center advised transmission valves, sensors, and seals replacement needed; no manufacturer-issued recall identified by owners
Transmission Disengagement While Driving
Transmission unexpectedly disengages or drops into neutral while vehicle is in motion on highway or city streets, creating sudden loss of power and control. Vehicle can be restarted and resumes normal operation temporarily. Pattern of recurrence in some cases.
When: Low mileage to 100,000+ miles; recurrent within days or months
Symptoms owners cite: Transmission suddenly disengages into neutral; Loss of power and acceleration while driving; Dash lights turn red upon failure; Vehicle coasts without drive engagement; Cruise control disengages before event
Repairs/costs cited: Transmission speed sensor reset performed electronically; service advisor noted replacement of valves, sensors, and seals needed but parts not specified
Transmission Harsh Shifting and Jerking
Transmission jerks, lurches, or violently downshifts multiple gears without warning or driver input. One owner reported violent lurching at 40–45 mph on wet and dry pavement causing loss of control and occupants thrown toward windshield.
When: 29,700–113,000 miles
Symptoms owners cite: Violent jerking when shifting gears; Violent downshift of multiple gears at highway speeds; Vehicle lurches forward unexpectedly; Loss of vehicle control on wet or dry pavement; Skidding
Transfer Case Defect and Vibration
Transfer case exhibits defective material causing vibrations and shuddering, particularly when turning. Owner discovered that Mercedes issued a January 2009 manufacturer bulletin specifying defective transfer cases installed at production in 2007. One owner's transfer case oil change temporarily improved but did not resolve the issue.
When: 74,563 miles; transfer case oil changed at 30,000 miles by previous owner
Symptoms owners cite: Vibrations from powertrain when turning; Shuddering when making sharp turns at low speeds
Repairs/costs cited: Transfer case oil change provided slight temporary improvement; full transfer case replacement required; repair cost approximately $3,200 (with 25% manufacturer coverage, owner's out-of-pocket $2,400)
Recalls/TSBs owners mention: January 2009 manufacturer bulletin identified defective transfer cases; manufacturer agreed to cover only 25% of parts cost; service representatives at dealerships reportedly told multiple customers of transfer case problems
Engine Shutdown While Driving
