The electronic warning sign for unlocked seat belt comes on while the car is moving, including at high speed on freeways. Unlocking and re-locking the seat-belt does not fix the problem. This problem has been occurring on and off for a couple of years and I am concerned about the potential the airbag may not deploy appropriately in case an accident/collision.
While driving to get on the freeway from on ramp, miss judge and lost control of the steering wheel, vehicle flip from front to back on the ditch side of the road, driver was wearing a seat belt but got thrown out due to setbelt malfunction. Front airbag on steering and passenger side did not deployed, driver sustained broken spinal (neck), trauma brain injury, broken collar bones, bruised lungs, two broken arms two broken legs.
Certified pre-owned dealership bought Mercedes Benz 2003 c-240 4-matic. Purchased with 41k miles in 2008. Approximately 6/2013 the srs light came on stating 1 malfunction on the cluster relating to restraint system. Advised of numerous cases of this defect in model year 2003. Due to warranty expiration the issue has yet to have professional diagnostics. The light and cluster notification remains to date at 76k miles.
The srs and numerous other malfunctions come on. The headlights and dash lights along with the blinkers are turn on and off by themselves. At first turning the car off the malfunctions went away only to come back a few minutes later. I find this to be very dangerous since the air bags, seat-belts wont work in a accident. Along with if lights go out while driving at night. This problem has happened to me twice before after paying thousand to have it fixed it reappears after a year. I have researched and it seems that everyone is having this same problem due to faulty wire and sensor.
