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.

MY 2008 MERCEDES BENZ 300C STARTED THEN SHUT OFF IN MY DRIVEWAY. I HAD THE CAR LESS THAN 30 DAYS FROM PURCHASE. I CALLED THE DEALER AND HE CAME AND DID SOMETHING TO THE FUSE BAND IT START ED. NEXT DAY SAME THING, STARTED THEN SHUT OFF. I HAD IT TOWED TO MY MECHANIC, IT TOOK HIM TWO WEEKS TO FIGURE OUT WHAT WAS WRONG WITH IT. HE NARROWED IT DOWN TO THE IGNITION SWITCH. HOWEVER, HE WANT AUTHORIZED TO ACCESS THE IGNITION, SO IT HAD TO BE TOWED TO THE DEALER. THE DEALER CAME BACK AFTER 2 WEEKS AND SAID IT WAS THE FUEL PUMP. FINE, I PAID A LITTLE OVER $1K FOR THE DESPAIR. I GO TO PICK IT UP THEN I'M TOLD IT SHUT OFF. THIS IS AFTER A FULL DIAGNOSTIC TEST. MIND YOU, MY MECHANIC CALLED THE REP AT MERCEDES BENZ AND TOLD THEM EXACTLY WHAT THE ISSUES WAS AND THEY IGNORED IT. FAST FORWARD, I TELL THEM IN MY FRUSTRATION TO GO AND FIX THE CAR. I GET A QUOTE OF 878, AND THAT THEY WOULDN'T CHARGE FOR LABOR, PARTS ONLY. THEY CLAIM THE PARTS HAD TO BE ORDERED FROM GERMANY. TWO WEEKS LATER, A FULL MONTH AND A HALF OF WAITING FOR MY CAR, THE DEALER TELLS ME THE COST IS NOW 1919. LUDICROUS! THEY CLAIM THAT I NEEDED A KEY, THAT MY KEY WASN'T WORKING. WHAT? MY KEY WAS WORKING JUST FINE. THE C300 IGNITION ISSUES ARE OVERWHELMING AND NEED TO BE RECALLED. BUYER BEWARE!
THE VEHICLE WILL NOT START AND DOESN'T RECOGNIZE THE KEY. THE VEHICLE WAS COMPLETELY DEAD AND HAD TO JUMP START IT. I DROVE THE CAR TO HAVE THE BATTERY REPLACED THINKING THAT WAS IT. WHEN I ARRIVED AT THE GARAGE, THE VEHICLE WOULD NOT RESTART AND HAD TO BE TOWED TO THE DEALERSHIP FOR REPAIRS AS THE DEALERSHIP WAS THE ONLY ONE THAT COULD DIAGNOSE AND REPAIR.
TAKATA RECALL MY AIRBAG IS NOT WORKING, AND MY LIGHTING HAS A PROBLEM . MY BACK LIGHT STAY ON ALL OF THE TIME EVEN WHEN THE CAR IS OFF .I JUST BOUGHT THE CAR 3 WEEKS AGO AND I JUST REALIZED THAT.
