My 2013 Mercedes-Benz C350 with 78,000 miles usually makes a rattling sound for a few seconds when I start it. The local dealership diagnosed the problem as a stretched timing chain. They want to replace the timing chain adjusters, four camshaft adjusters, and timing chain. They quoted $9,800 for the job. The car's not worth $10,000.
Mercedes had a recall of C350's for this exact problem but the VIN on my car is too new to be included in the recall.
Is it dangerous to drive the car if I don't get it fixed?
I’m not sure if it is an interference engine or not, but in the case of interference engine, if the timing chain breaks, you should say goodbye to engine.
