| Description of the problem | Around 52,000 miles the check engine light came on. I took the vehicle to a mercedes benz dealer service department and was notified that the balance shaft needs to be replaced. In order to replace the balance shaft, the engine needs to be taken out of the vehicle and taken apart. Estimated cost $4,000 to $7,500. The service dept. Told me that it was due to a part that was not hardened properly during manufacturing. There is a technical service bulletin (s-b-03. 30/08i) that was originally issued in 2007, however it seems like mercedes benz knows that the check engine light (on the majority of these vehicles) will not come on until after 50,000 miles, when the warranty has expired. Since this fix is a huge expense, they are not going to issue a recall even though it is clearly a safety concern. If we would've have continued to drive the vehicle in this condition, eventually the balance shaft would have continued to break its teeth resulting in engine failure. Continuing to drive the vehicle in the condition is not safe, it is a matter of time before the vehicle stops running and the engine would need to be replaced. The service department replaced our balance shaft, the parts used are too numerous to list along with labor codes. Here is a brief breakdown: 28. 8 labor hours total $2,940. 48, parts $1,263. 50 (consumer cost), $925. 49 (net cost). The failure has been corrected, however the service dept. Told me all of these vehicles made during this time will eventually have this failure and it's a safety concern, not to mention a very expensive repair. I feel there should be a recall issued for these vehicles and mercedes benz should be required to notify consumers of this failure. I was an original purchaser and had mine repaired, however there are people out there buying these vehicles used unaware of the problem, not only stuck with a $4,000 + repair, but also unaware of the safety hazard. Mercedes benz should take responsibility. |
