What stands out
No new NHTSA airbags complaint has been filed on this vehicle in over 21 years — the issue may be aging out of the active population.
The failure pattern owners describe
Owners of 2005 E-Class vehicles describe widespread SRS system failures centered on faulty wiring and connectors in the steering column. Multiple owners report the SRS warning light coming on unexpectedly; in at least two cases, the same repair (wiring replacement to the steering wheel control module) failed again within months. One owner paid over $2,800 for a complete seat frame replacement when a seat occupancy sensor failed to diagnose properly. A dealership service manager noted 20+ vehicles waiting for parts due to the same failure.
The passenger-seat occupancy sensor is unreliable: it illuminates the warning light when an adult sits down, refuses to arm for children, and flickers on and off randomly—making it impossible to know if the airbag will actually work. In crash events, front passenger airbags have failed to deploy in frontal impacts, and side airbags have not inflated during T-bone collisions despite the vehicle being struck directly on the driver side. Two owners report airbags deploying spontaneously: once when the parked vehicle sat unattended in a driveway with no ignition, and once when a hammer blow was struck to the car's underside during service work. One crash involved side-airbag deployment causing burn and lesion injuries to a child passenger. Smoke appeared in at least one low-speed collision during partial deployment, linked to a Takata recall. The inferior zinc-plated connector pins used instead of gold plating has been cited as a design choice that may contribute to corrosion and circuit faults.

Failure modes owners describe
Front passenger airbag non-deployment
Front passenger airbag failed to deploy in frontal or near-frontal crashes despite driver and other airbags deploying. Narratives #1 and #14 document crashes where the front passenger airbag did not inflate; #14 was determined to be a lateral impact where deployment was not required, but #1 involved a tree strike with right-of-center impact to the vehicle front.
When: #1: tree strike impact; #14: frontal/lateral impact event
Symptoms owners cite: Front passenger airbag remains stowed during crash; Other airbags (driver front, side-curtain) deploy normally
Codes mentioned: No specific codes reported
Repairs/costs cited: #1 referred to CHP MAIT investigation; #14 determined performance was correct for lateral impact
Passenger-seat occupancy sensor malfunction
Passenger airbag occupancy detection system failed to operate reliably. Warning light illuminated incorrectly when an adult sat in the seat, then failed to activate the airbag for lighter passengers or children. Light behavior was erratic, making it impossible for the driver to know if protection was functional.
When: Intermittent during vehicle operation
Symptoms owners cite: Warning light illuminates when adult passenger seated; Airbag does not activate for child or lightweight passenger; Light turns on and off randomly; Inconsistent behavior prevents driver from knowing if system works
Repairs/costs cited: Dealer attempted repair four times without success
Recalls/TSBs owners mention: Dealer planned to escalate to manufacturer
SRS warning lamp and connector/wiring faults
SRS warning light illuminated indicating system malfunction. Root causes identified in some cases include defective connectors and compromised wiring in the steering column. Connectors used inferior materials (zinc-plated pins instead of gold). Repairs often required rewiring or connector replacement, and failures recurred in some vehicles despite repairs.
When: Varies; #5 first at 82,000 miles on a 2005 E320; recurrences in same vehicle within months; #8 occurred before or at 30,000 miles
Symptoms owners cite: SRS warning light illuminated on dash; Malfunction message displayed indicating SRS failure; Vehicle deemed unsafe to drive until repaired; Intermittent failures: system would fail, be repaired, then fail again
Codes mentioned: Error code 9103 (defective connector and wire, airbag line to steering column), Codes related to steering wheel control module
Repairs/costs cited: #5 required wiring replacement to steering wheel control module; repair was repeated within months. #8 replaced airbag connector; owner noted inferior zinc pins vs. gold-plated design in older Mercedes. #12 required seat control module replacement (P/N 211 870 05 26) and ultimately full seat frame replacement at cost exceeding $2,800. #6 involved parts shortage with 20+ vehicles at dealer awaiting repairs.
Recalls/TSBs owners mention: #6 service manager stated over 20 vehicles had same failure awaiting parts. Takata recall mentioned in #2 and #11.
Unexpected airbag deployment
Airbags deployed without collision or when vehicle was stationary and not in operation, indicating a sensor or electrical system failure. One case involved airbags deploying when a hammer blow was struck to a bolt on the underside during service work. Another case involved side airbags deploying when the car was parked in a driveway with no key in the ignition and no impact.
When: #9 approximately one month after a minor accident that caused no deployment; #10 during service work with vehicle elevated on lift and ignition in accessory position
Symptoms owners cite: Airbags deploy while vehicle is stationary and unattended; Deployment triggered by mechanical vibration or impact to undercarriage during service; Deployment with ignition off or in accessory mode; Loud noise and physical impact to occupants
Repairs/costs cited: #9 caused head injury from unexpected side airbag deployment. #10 driver-side side airbags deployed after hammer strikes to undercarriage bolt.
Airbag warning chime malfunction
Front passenger airbag warning chime sounded continuously on vehicle start even when no passenger was seated. Sounding stopped only when seat belt was buckled, despite the seat being empty.
When: At vehicle start; #4 at approximately 82,000 miles
Symptoms owners cite: Audible warning chime from passenger airbag circuit at start; Chime persists until seat belt is fastened; Chime sounds with no occupant in seat
Recalls/TSBs owners mention: Mercedes-Benz dealership declined to diagnose the vehicle
Smoke generation during airbag deployment
Smoke visible inside and outside vehicle during airbag deployment in a low-speed collision. Narrative attributes this to a Takata recall issue.
When: #2 during low-speed swerve and curb impact
Symptoms owners cite: Smoke visible inside vehicle during partial airbag deployment; Smoke visible on exterior near passenger side; Occurred in low-speed impact (swerve and curb strike)
Repairs/costs cited: Vehicle towed; no repair attempted
Recalls/TSBs owners mention: Takata recall cited; manufacturer notified
Airbag deployment causing injury
Side airbag deployment from a T-bone collision at an intersection caused severe injury to a 9-year-old child passenger, resulting in lesion and burn injuries from the airbag inflation impact.
When: #13 T-bone impact at intersection
Symptoms owners cite: Side airbag deployed during T-bone impact; Child occupant in rear or side seat suffered lesion and burn injuries from deployment impact
Side airbag non-deployment in lateral impacts
Side airbag failed to deploy when vehicle was struck on the driver side. One case was a T-bone intersection collision where the side airbag did not deploy despite the lateral impact.
When: #16 during left turn when struck on driver side; #17 at stop-sign collision
Symptoms owners cite: Side airbag does not inflate during lateral impact; Occupant injury occurs without airbag protection; Vehicle occupants reported injuries
