Car has been in and out of the shop. Initially I have been contacting Mercedes about airbag messages and continued message of SRS Malfunction on dashboard. Airbags had been recalled and supposedly replaced on multiple occasions. This SRS continues to remain even after repair or being seen for this issue only for other components to have failed and me having to pay for those in the process. The SRS Malfunction remains an issue until the next issue is affected. Recently an entire Electronic SAM Module Component was replaced as the culprit only to have more issues and the SRS remained. Mercedes has contended that each time they saw the vehicle the the SRS Malfunction was not the problems while other documents were repaired such as battery and SAM. In the meantime since then the car has stalled, components that were working are no longer inoperable. There was a recall that was applied to only specific vehicles of my model year which state the SRS Malfunction was to be replaced and made whole. I never received one of those notices and I will note that my vehicle obviously was affected and should also have this component replaced as it fits the same model year and make of the issues Mercedes has repaired already on affected vehicles. This issue has been on going for several years and Mercedes has failed to rectify this component that makes it dangerous and causes safety concerns for us with the understanding that their note on their website about the SRS Malfunction appeared to me a cop out for them to not be responsible for the fix and recall thsr may have affected more vehicles than its originally accessed number. Instead of fixing this issue they continually find other repairs they indicate as the issue only to end up right back with the same SRS Malfunction and stalling issues with vehicle once again and want to use excuse of car's age as issue and failing to acknowledge and address the SRS Malfunction. Your system would not allow file upload. I can still provide

My car had the Takata airbags that were recalled. It says the recalls were repaired but my vehicle is saying that the driver-side airbag has malfunctioned. I haven't been in any accidents. So I contacted Mercedes and they could not find verification that the previous open recalls were ever fixed.

When I was driving, the passenger active headrest suddenly deployed and pop out. I’m glad on one was on the passenger seat, and the airbags did not deployed. I’m concerned about the safety of airbags accidentally deploy in the future with the broken headrest.

BANK IN 2017 THE SRS AIRBAG SAFETY LIGHT COMES ON AND NEEDS REPLACEMENT. THIS WAS A RECALL. I WAITED UNTIL LATE 2018 WHEN THE AIR BAGS CAME INTO THE MERCEDES DEALER IN ANNAPOLIS TO REPLACE FOR RECALL. AFTER THAT THE SRS AIRBAG SAFETY LIGHT STILL COMES ON. WE TAKE IT BACK TO MERCEDES FOR THEM TO CHECK AND CLEAR. THEY SAY IT WAS DONE. SAME LIGHT COMES BACK ON. WE TAKE IT BACK TO MERCEDES TODAY 2/25/2020 AND THEY SAY ITS A SAFETY FAULTY SEAT BELT SWITCH. THEY WANT TO CHARGE ME $1100 TO REPAIR. I TOLD THEM THEY SHOULD HAVE FIXED EVERYTHING PROPERLY AND I STILL BELIEVE THAT THEY JUST NEVER RESET OR CLEARED THE SRS AIRBAG ALERT LIGHT SO THAT WE WOULD HAVE TO PAY SOME BOGUS MADE UP REPAIR. I BELIEVE THAT WE ARE BEING TREATED UNFAIRLY AND THAT THIS DEALER IS BEING DISHONEST. THE SRS AIRBAG LIGHT WAS NOT RESET AND IT IS STILL ON. HELP?
