Unable to start vehicle. Key turns but no crank. Service tech was able to release / unlock the steering wheel by violently shaking the steering wheel from left to right as if he was trying to break it. Something did release and he was then able to start the vehicle. Brought the car directly to dealership and I was quoted $1018 for the steering wheel lock. Looks like this is a well documented…

What stands out
Of the 16 model years of Mercedes-Benz C-Class we track for steering problems, this one carries the most owner complaints on file — 169.
Owners have filed 169 steering 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.
The failure pattern owners describe
The 2008 C-Class steering and ignition system exhibits a catastrophic and widespread failure pattern that Mercedes has known about since 2008 yet refuses to recall. The electronic steering lock (ESL) and electronic ignition switch (EIS) fail suddenly with no warning, leaving cars immobilized and drivers stranded. One moment the car runs fine; the next, the steering wheel locks, the key won't turn the ignition, the car won't shift out of Park, and the dash shows "Remove key from ignition."
The failure happens at random—sometimes after 30,000 miles, sometimes near 100,000. Battery, starter, and alternator all test normal. Locks and lights work. But the car is dead. Towing becomes a nightmare because the steering is locked and the transmission won't shift to neutral. Some owners waited days for multiple tow trucks to move the vehicle just a quarter-mile. Only Mercedes dealerships can diagnose and repair it, and they charge $800 to $3,400 per repair. At least one owner reports the same part failed again after replacement.
Mercedes issued Service Campaign 2008020003 in March 2008 and claims it affects "approximately 10 vehicles," yet hundreds of owners report the same failure across forums and NHTSA complaints. Mercedes admits internally it's a "common" problem but refuses to recall it. Some dealership techs privately acknowledge they see this failure repeatedly on these cars. One owner's extended warranty explicitly excludes this component. The lack of warning, the sudden loss of steering control while the car could theoretically be in motion, and the manufacturer's refusal to take responsibility all point to a serious design or manufacturing defect.

Failure modes owners describe
Electronic Steering Lock (ESL) / Electronic Steering Lock Module (ELV) Failure
The electronic steering lock module fails, rendering the steering wheel locked in position and preventing the vehicle from starting. This is the most prevalent failure mode across the narratives.
When: Occurs at any time—while parked, after short trips, or occasionally during driving. No consistent mileage threshold; failures reported between 30,000 and 217,000 miles, though many occur in the 50,000–90,000 mile range.
Symptoms owners cite: Steering wheel locked and unable to turn; Key will not turn the ignition or turns but engine does not crank; Vehicle cannot shift out of Park; Message on dash: 'Remove key from ignition'; No warning lights or advance indication of failure
Codes mentioned: B212171 (Relay 1 circuit malfunction—actuator blocked), B215F71 (Relay 1 circuit malfunction—actuator blocked), U016800 (Communication with electronic ignition lock malfunction)
Repairs/costs cited: Replacement of ESL module; parts cited include P/N A204-545-81-32, A204-545-14-08. Repair costs reported: $800–$3,457 (typically $1,100–$1,500). Only Mercedes dealership can perform repair. Some owners report the part fails again after replacement (see complaint #36). Towing costs additional $55–$175; many tow trucks unable to tow vehicle because it will not shift to neutral or steering is locked at an angle.
Recalls/TSBs owners mention: Mercedes issued Service Campaign Bulletin 2008020003 (March 2008) for EIS replacement, yet classified the issue as affecting 'approximately 10 vehicles' despite hundreds of documented complaints. Mercedes has not issued a recall. Company admitted issue is 'common' but refuses financial responsibility. Extended warranty programs exclude this component from coverage.
Electronic Ignition Switch (EIS) / Electronic Ignition System Malfunction
The electronic ignition switch or electronic ignition system fails to recognize or respond to the key, preventing engine start. Often occurs concurrently with steering lock failure.
When: Sudden failure with no warning. Failures reported across vehicle lifecycle; many occur near or after warranty expiration.
Symptoms owners cite: Key turns but engine does not crank or start; Display shows 'Remove key from ignition'; All electrical accessories (lights, radio, locks, windows) operate normally; Battery tests normal; starter tests normal; Car may have been working normally minutes before failure
Codes mentioned: U016800 (Communication with electronic ignition lock malfunction), A10D00 (Power supply too low), C14600 (Communication with central gateway malfunction)
Repairs/costs cited: Replacement of EIS control module (P/N A204-545-14-08). Costs: $561–$1,900 depending on labor and associated parts. Reprogramming of keys required (cited as $375–$595). Only Mercedes dealership can diagnose and repair; independent shops cannot access the proprietary diagnostics or parts.
Recalls/TSBs owners mention: Service Campaign 2008020003 issued March 2008; however, Mercedes maintains no recall exists. Company representatives told owners this is a 'known issue' but refused financial responsibility. Some owners report dealership service advisors acknowledge the defect but cannot force a recall.
Water Intrusion to Front SAM Module (Signal Acquisition and Actuation Module)
Water enters the driver-side front SAM module through the windshield water drain adjacent to the driver-side fuse panel, causing electrical short circuits and cascading system failures.
When: Complaint #1 documents this; timing appears related to weather or drainage design flaw.
Symptoms owners cite: Vehicle dies or stalls while driving; Steering lock engages during malfunction, locking the steering column; Ignition key loses communication with ignition system; Instrument cluster only illuminates when door is opened; BCM (Body Control Module) loses active state; Multiple relay and output circuit malfunctions detected; Magnetic interference field detected
Codes mentioned: B215F71 (Relay 1 circuit 15R malfunction—actuator blocked), B212171 (Relay 1 circuit 15 malfunction—actuator blocked), B172B15 (Front footwell illumination output short or open circuit), B179715 (Left standing light 2 short or open circuit), B126231 (Magnetic interference field detected), B126322 (LIN message loss from compass module), B127A54 (Compass module not calibrated), B182811 (Remote trunk opening output short to ground), U016800 (Communication with electronic ignition lock malfunction)
Repairs/costs cited: Requires comprehensive repair of SAM module and potentially multiple associated control units; exact costs not specified in complaint #1. Repair is complex and only available at Mercedes dealership.
Recalls/TSBs owners mention: None documented in complaint #1.
Intermittent Start Failures with Steering Column Sensitivity
Vehicle exhibits intermittent start failures, sometimes temporarily resolved by manipulating or adjusting the steering column position, suggesting a contact or sensor issue within the steering column assembly.
When: Complaint #4 documents three incidents over several months.
Symptoms owners cite: Car will not start on first attempt; Adjusting steering column (raising or lowering wheel) sometimes restores ability to start; Instrument cluster lights illuminate only after steering wheel adjustment; Multiple incidents without stored diagnostic codes; Eventually progresses to permanent failure with steering wheel locked in turned position
Codes mentioned: None retrieved in complaint #4
Repairs/costs cited: No repair completed in complaint #4; vehicle remained non-functional at time of filing.
Recalls/TSBs owners mention: None documented.
Complete Vehicle Lockup (Multiple System Seizure)
Vehicle suffers catastrophic failure in which steering, transmission, windows, and ignition all become unresponsive simultaneously, with all systems 'seized up' and non-functional.
When: Complaint #5 documents vehicle parked for less than one day before failure; also involved exposure to ice storm.
Symptoms owners cite: Vehicle will not start; Transmission stuck and will not move into any gear (stays in Park); Steering locked; Windows inoperable; No diagnostic information available to independent shops; Towing extremely difficult; vehicle slips back into Park
Repairs/costs cited: Complaint #5 notes independent repair shops were unable to 'unseize' systems and stated only Mercedes could repair. Exact parts and costs not disclosed; vehicle was towed to dealership for repair. Towing required 3 separate tow trucks and 2+ days to complete 1/4 mile transport.
Recalls/TSBs owners mention: None effective; roadside assistance coordination was described as poor.

What owners are reporting 3 most recent
Car will not start, failure in the electrical steering system
The steering wheel electronic lock, shut down my car. I drove to the doctors office and it stop working. It would not start. I found out that there are 1000 of complaints from other people who had the same problem.. But since there isn't a recall we would be subjected to paying out of our pocket. About $950.
