Among the 15 model years of Mercedes-Benz E-Class in our records for steering problems, this one ranks #3 by owner-complaint volume.
The failure pattern owners describe
Owners report multiple steering system failures on the 2012 E-Class. The most severe involves the electronic drive motor bolts corroding through and separating from the steering rack—this causes complete steering lockup with loud hammering from the front end and renders the vehicle immobile. One owner at 75,000 miles in a salt-exposed region faced a $4,300 repair bill. Mercedes recalled 21,500 vehicles in Canada for this exact defect but has not issued a US recall, despite high salt use in Buffalo and Detroit.
Electronic Steering Lock (ESL) failures disable the entire vehicle—no start, no functions, nothing responsive. Owners report the car simply becomes "dead" with no warning. Multiple owners cite this as a well-known issue on Mercedes forums and YouTube.
Power steering malfunction warnings appear mid-drive or at startup, making the steering wheel extremely stiff and difficult to turn. One case involved replacement of the entire power steering assembly at just 1,000 miles. Battery replacement may temporarily resolve the warning but often fails again permanently.
Less common issues include gear shifter detachment from the steering column, steering wheel collar melting while parked, and steering wheel lock. Dealers acknowledge the problems but lack permanent solutions in some cases, with parts reported on back order.

Failure modes owners describe
Electronic Steering Box Bolt Corrosion
Aluminum bolts securing the electronic drive motor to the steering rack corrode and fracture, particularly in salt-exposure environments. The motor separates from the steering rack, causing complete steering lock and loss of vehicle control.
When: 75,000 miles reported in one case; mileage varies across narratives
Symptoms owners cite: Loud hammering or banging noise from front end; Complete loss of steering ability; Vehicle becomes immobilized and undrivable; Steering wheel will not turn
Repairs/costs cited: $4,300 CAD reported for repair; involves replacing corroded bolts and steering motor assembly. Parts reported on back order at dealers.
Recalls/TSBs owners mention: Mercedes-Benz recalled 21,500 vehicles in Canada but did not extend recall to USA. TSB exists. Dealers aware of the issue.
Electronic Steering Lock (ESL) Failure
The Electronic Steering Lock module fails completely, rendering the vehicle unable to start or move. No warning lamps precede failure. Entire vehicle becomes disabled with all functions locked out.
When: Mileage variable; narratives report 69,000 miles in one case; occurs at various mileages per owner reports
Symptoms owners cite: Vehicle will not start or crank; Key fob not detected by ignition; All vehicle functions locked; Cannot shift out of park or into neutral; Vehicle completely immobilized; No warning lamps or messages before failure
Repairs/costs cited: Requires replacement or reprogramming of electric steering rack. Owners report this is a common failure across multiple Mercedes forums and YouTube discussions.
Recalls/TSBs owners mention: Mercedes-Benz aware of problem; TSB published regarding ESL failure. No recall issued in USA.
Power Steering Malfunction Warning and Loss of Assist
Power steering system fails or becomes unresponsive, triggered by weak battery or steering system fault. Warning light illuminates but system does not recover. Steering becomes stiff and difficult to control.
When: Various mileages; one case at 1,000 miles; failures occur during startup and while driving
Symptoms owners cite: Power steering malfunction warning light; Steering wheel very difficult or stiff to turn; Loss of power steering assist while driving; Problem recurs after battery replacement; Warning persists even after vehicle restart
Repairs/costs cited: One case resolved with battery replacement but failure recurred. Power steering assembly replacement performed in at least one case (1,000 miles).
Steering Column/Gear Shifter Separation
Gear shifter detaches from the steering column without warning, compromising both steering control and transmission operation.
When: 420,000 miles
Symptoms owners cite: Gear shifter detaches from steering column; No warning light illuminated before failure
Repairs/costs cited: Vehicle towed; not repaired. No diagnosis obtained.
Steering Wheel Collar Melting
Plastic collar around the base of the steering wheel melts while vehicle is parked, exposing internal steering components. No accident or external cause identified.
When: Occurred while parked in driveway
Symptoms owners cite: Plastic collar around steering wheel melts; Exposure of internal steering wheel components; Happens without apparent external cause
Repairs/costs cited: Dealer unable to explain cause. Repair cost to owner; no recall or warranty coverage offered.
