| Description of the problem | In a mercedes benz c250 2012-2014 there has been many reports across the united states where camshaft adjusters+timing chain components fail/break. This is a highly risk and safety matter that needs to be addressed by mercedes benz as recall. Being newer model cars, the timing chain and camshaft adjusters should not fail. Not even at 100k miles. Some of these models has had their camshaft adjusters+ timing chain fail at 46k miles. Why is mercedes not owning up to these factory faults? Why are new models that are not even 10 years old have this kind of issue? This defect can cause major accidents on the road. Cause you go at highway/freeway speed 60 mph and your timing chain breaks, you can cause a major accident with other cars, and injure your own self and passengers. Can you imagine for those who have babies and drive these vehicles. Why is a hugecompany like mercedes not owning up to these defects? Instead they want to charge $4,000-$8,000 to get this repair done. Even if you have warranty they still hesitate on getting this repair done. I just want to be heard because being one of the many reports with this issue on these vehicles, it's concerning to see many of these vehicles still out on the road. When these parts have are failing, you will get a check engine light that reads "p034062" camshaft position sensor bank 1 electrical failure" after getting diagnosed by many shops, and even mercedes benz dealer all the test say the wiring and everything else is ok. Camshaft adjusters are failing will need replacing + timing chain & tensioner. But why on such a newer car? It should run about 200k miles until it needs a new timing chain. Cars being serviced at correct interval & being well maintained. This should not be a issue. Engine when start up will rattle. It will sound like engine is falling apart. Plus car will run really rough. |
