1974 Mercedes-benz 450sl problems
The Mercedes-Benz R107 and C107 are sports cars which were produced by Mercedes-Benz from 1971 until 1989, being the second longest single series ever produced by the automaker after the G-Class. They were sold under the SL (R107) and SLC (C107) model names in a variety of names indicating the displacement of the engines.
The R107/SL was a two-seat convertible with a detachable roof. It replaced the W113 SL-Class in 1971 and was replaced by the R129 SL-Class in 1989.
The predecessor W113 was notably successful in North America, with 19,440 units (40%) of 48,912 total units sold in the US. The R107 and C107 were even more focused on the American market, with specialized engines, bumper designs, headlights, and emissions management designs. The R107 and C107 sold 204,373 units in the US (68%) of 300,175 total units sold (excluding grey market sales into the US).
During its production run, the SL was the only roadster offered by Mercedes-Benz. The C107/SLC was a four-seat car with a fixed roof and an optional sliding steel sunroof. It replaced the W111 Coupé in 1971 and was in turn replaced by the C126 S-class coupé in 1981.

STEERING PROBLEM
- Date Of Incident: 2017-07-07
- VIN: 10704412016
- Components: STEERING
- Summary: AS THE SECOND, AND RELATIVELY NEW, OWNER OF A LOW MILEAGE VINTAGE MERCEDES, I HAVE BEEN INFORMED IN JUNE 2017 THAT THERE IS AN OPEN SAFETY RECALL FOR THIS MODEL DUE TO A DESIGN FLAW THAT CAUSES CRACKS IN THE SUBFRAME, LEADING TO A POTENTIAL "CATASTROPHIC FAILURE" OF THE STEERING SYSTEM. I HAVE TAKEN ALL THE STEPS RECOMMENDED, INCLUDING TAKING THE CAR FOR ASSESSMENT AT A MERCEDES DEALER IN JULY OF 2017 TO BE TOLD THAT THIS SPECIFIC CAR DOES HAVE A CRACKED SUBFRAME, YET MERCEDES BENZ US IS REFUSING TO HONOR THE OPEN RECALL CAMPAIGN, SAYING THAT NO PARTS ARE AVAILABLE AND THAT THERE IS NOTHING THEY CAN DO TO OFFER ASSISTANCE. THIS REFUSAL HAS LEFT ME BOTH UNABLE TO DRIVE THE CAR SAFELY, OR TO ETHICALLY SELL IT TO ANOTHER COLLECTOR DUE TO THE HIGH RISK INVOLVED, INCLUDING THE POTENTIAL FULL LOSS OF THE STEERING MECHANISM AS THE WHOLE SUBFRAME HAS BEEN KNOWN TO DROP OUT OF THESE CARS WHILE MOVING. MY UNDERSTANDING IS THAT THE RECALL WAS ISSUED IN DECEMBER OF 1985 WITH THE RECALL NUMBER OF 1985120001- 851211. ANY ASSISTANCE WOULD BE GREATLY APPRECIATED SINCE THE MANUFACTURE IS REFUSING TO SUPPLY A NEW SUBFRAME (AS THEY HAVE BEEN DOING AT AN EARLIER DATE FOR THE SAME MODEL), COVER THE COSTS OF A USED SUBFRAME, OR SUGGEST AN OTHER OPTIONS FOR REPAIR.
